Cross Install Gentoo

2018-07-09T16:25:24Z

Jgeiss: /* Prepare cross development system */

= Introduction =

These instructions are for installing a recent Gentoo Linux on the OpenPandora
handheld console. The system will be installed and booted from a SD-card. The
Gentoo Linux will be cross-compiled on another desktop computer also running
Gentoo Linux.

It is not necessary to follow all instructions exactly. Some of them can be
changed to your own needs.

'''The system currently supports only the text console and no X11 or sound.'''
'''Also a lot of features are missing.''' See "Open issues" at the end.

== Prerequisites ==

These instructions assume the following prerequisites:

* Good knowledge in Gentoo Linux.
* A desktop computer running Gentoo Linux. Other Linux is, of course, also possible but requires proper adaption of these instructions.
* An OpenPandora handheld console.
* A SD-card with least 8 GB size.
* A USB cable to connect the Pandora to the desktop computer.

== Improvement ==

Due to the constant changes of the Linux kernel, GNU software, etc. this
document will be outdated very quick. To avoid this, help is always appreciated
improving this document. If you can update, improve, add or complete this
document, don't hesitate to do so.

= Prepare/install cross compile system =

To perform the cross-compilation a cross compiler and QEmu must be installed
on the desktop computer. QEmu will help a lot for compiling packages which
will not properly cross compile.

== Install cross compiling system ==

For compiling software for an ARM controller a cross compiler must be installed.

We can use ARMv7 using either soft float (armv7a-softfp-linux-gnueabi) or hard
float (armv7a-hardfloat-linux-gnueabi).

<pre>export CROSSDEV_TARGET=armv7a-softfp-linux-gnueabi</pre>

or

<pre>export CROSSDEV_TARGET=armv7a-hardfloat-linux-gnueabi</pre>

The additional portage tree in "/usr/local/portage-crossdev" will hold all
information for emerging the cross build system (cross compiler and tools).

To prepare emerging a cross compiler, execute the following commands.

<pre>
su
umask 0022

emerge -av crossdev

mkdir -p /usr/local/portage-crossdev/{profiles,metadata}

echo 'local-crossdev' >/usr/local/portage-crossdev/profiles/repo_name
echo 'masters = gentoo' >/usr/local/portage-crossdev/metadata/layout.conf
echo 'thin-manifests = true' >>/usr/local/portage-crossdev/metadata/layout.conf
chown -R portage:portage /usr/local/portage-crossdev

echo '[local-crossdev]' >/etc/portage/repos.conf/crossdev.conf

echo 'location = /usr/local/portage-crossdev' \
>>/etc/portage/repos.conf/crossdev.conf

echo 'priority = 10' >>/etc/portage/repos.conf/crossdev.conf
echo 'masters = gentoo' >>/etc/portage/repos.conf/crossdev.conf
echo 'auto-sync = no' >>/etc/portage/repos.conf/crossdev.conf
</pre>

The portage tree for emerging the cross build system is set up. Now we have to
find out which versions of the cross build components are about to be installed.
The target system will get binutils, gcc, glibc and linux-headers of a certain
version. The same version should be installed in the cross build system.

<pre>
export BINUTILS_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-devel/binutils/binutils-*.ebuild | tail -1 | \
awk 'match($0, ".*/binutils-(.*).ebuild", v) { print(v[1]); }')

export GCC_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-devel/gcc/gcc-*.ebuild | tail -1 | \
awk 'match($0, ".*/gcc-(.*).ebuild", v) { print(v[1]); }')

export GLIBC_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-libs/glibc/glibc-*.ebuild | tail -1 | \
awk 'match($0, ".*/glibc-(.*).ebuild", v) { print(v[1]); }')

export LINUX_HEADERS_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-kernel/linux-headers/linux-headers-*.ebuild | tail -1 | \
awk 'match($0, ".*/linux-headers-(.*).ebuild", v) { print(v[1]); }')
</pre>

Now emerge the cross compiler.

<pre>
crossdev --binutils $BINUTILS_VER --gcc $GCC_VER --libc $GLIBC_VER \
--kernel $LINUX_HEADERS_VER --target $CROSSDEV_TARGET
</pre>

== Install QEmu ==

A lot of packages will not cross compile properly. QEmu will help for these
packages. Install it to emulate an ARM controller.

Edit /etc/portage/make.conf.

<pre>
nano /etc/portage/make.conf
</pre>

And add the following lines.

<pre>
QEMU_SOFTMMU_TARGETS=""
QEMU_USER_TARGETS="arm"
</pre>

Also enable the use flag static-user. This builds QEmu as static binary.
QEmu will be used later in a chroot environment of an ARM controller and will
be unable to access needed shared libraries. So it must contain all these
libraries by building it in a static way.

<pre>
euse -E static-user
</pre>

All the needed libraries for QEmu must also be available as library archive
(static libs). Emerging QEmu will request to emerge these libraries as
static variants, also. Create and add these libraries in the file
"/etc/portage/package.use/qemu". Look which libraries are needed.

<pre>
emerge -pv qemu
</pre>

And add them with the use flag static-libs. Here is an Example:

<pre>
>=net-misc/curl-7.53.0 static-libs
>=sys-apps/attr-2.4.47-r2 static-libs
>=media-libs/libsdl-1.2.15-r9 static-libs
>=sys-apps/dtc-1.4.1 static-libs
>=app-arch/bzip2-1.0.6-r7 static-libs
>=x11-libs/pixman-0.34.0 static-libs
>=dev-libs/libpcre-8.40-r1 static-libs
>=sys-libs/libseccomp-2.3.0 static-libs
>=net-fs/libnfs-1.9.7 static-libs
>=dev-libs/cyrus-sasl-2.1.26-r9 static-libs
>=dev-libs/gmp-6.1.0 static-libs
>=dev-libs/libaio-0.3.110 static-libs
>=sys-fs/xfsprogs-4.5.0 static-libs
>=sys-libs/zlib-1.2.11 static-libs
>=media-libs/libjpeg-turbo-1.5.0 static-libs
>=sys-libs/libcap-ng-0.7.8 static-libs
>=dev-libs/openssl-1.0.2k static-libs
>=dev-libs/glib-2.50.3-r1 static-libs
>=virtual/jpeg-0-r2:0 static-libs
>=media-libs/libpng-1.6.27 static-libs
>=sys-libs/ncurses-6.0-r1 static-libs
</pre>

Emerge QEmu.

<pre>
emerge qemu
udevadm trigger -c add /dev/kvm
</pre>

QEmu will execute ARM binaries on the desktop computer as if it would have an
ARM controller. To achieve this, register foreign binaries and start the
systemd service.

<pre>
ln -s /usr/share/qemu/binfmt.d/qemu.conf /etc/binfmt.d/qemu.conf
systemctl start systemd-binfmt
</pre>

Now our desktop computer is able to execute ARM binaries as well as his own
binaries.

== Install GIT ==

To get the kernel sources, GIT will be needed. Emerge it.

<pre>
emerge git
</pre>

Exit the root shell.

<pre>
exit
</pre>

Now the cross build system is ready to compile a Gentoo Linux for the Pandora.

= Install system =

== Prepare target file system ==

To build the system for the Pandora about 10 GB disk space is needed. Create a
directory "CrossDev" to store all data there.

<pre>
mkdir CrossDev
cd CrossDev
</pre>

In this directory two more directories will be created:

* One to store and build the Linux kernel.
* Another will store the whole system for the Pandora including QEmu which is not really a part of the system for Pandora, but it is needed as long as the building process runs.
* Some files and archives.

First get the Gentoo base system "stage3-armv7a-*.tar.bz2". Download it from
a suitable mirror of the Gentoo distribution. See
https://www.gentoo.org/downloads/mirrors for a list of mirrors.

Go to the directory "releases/arm/autobuilds". According to your target, enter

* "current-stage3-armv7a" for soft float (armv7a-softfp-linux-gnueabi),
* "current-stage3-armv7a_hardfp" for hard float (armv7a-hardfloat-linux-gnueabi).

There is a stage 3 file for ARMv7. Download this archive.

Example:

<pre>
wget http://mirror.eu.oneandone.net/linux/distributions/gentoo/gentoo/\
releases/arm/autobuilds/current-stage3-armv7a/stage3-armv7a-20161129.tar.bz2
</pre>

or

<pre>
wget http://mirror.eu.oneandone.net/linux/distributions/gentoo/gentoo/\
releases/arm/autobuilds/current-stage3-armv7a_hardfp/\
stage3-armv7a_hardfp-20161129.tar.bz2
</pre>

As long as we are cross compiling, we use "/usr/$CROSSDEV_TARGET" as working
directory. The cross compiler looks for libraries there and uses many references
to this directory. That's why "/usr/$CROSSDEV_TARGET" will be saved, so it can
be restored after the build.

<pre>
su
umask 0022
tar -cpjf ${CROSSDEV_TARGET}-saved.tar.bz2 -C /usr $CROSSDEV_TARGET
</pre>

Unpack the stage 3 archive into "/usr/$CROSSDEV_TARGET".

<pre>
tar --xattrs --numeric-owner -xpjf stage3-*.tar.bz2 -C /usr/$CROSSDEV_TARGET
</pre>

Sometimes there is a lot of garbage in the "tmp" directory. Remove it.

<pre>
rm -rf /usr/$CROSSDEV_TARGET/tmp/*
</pre>

Exit the root shell and go back to our working directory.

<pre>
exit
</pre>

== Compile/install kernel ==

The standard Gentoo kernel will not run on the Pandora (or, at least, takes too
much effort to make it run), so download a current kernel from
https://goldelico.com using GIT.

=== Download kernel ===

Download the kernel with GIT.

<pre>
git clone git://git.goldelico.com/gta04-kernel.git
cd gta04-kernel
</pre>

=== Compile kernel ===

Prepare an environment to cross compile the kernel. First call another shell
instance for saving the current environment. This instance is not really
necessary but it is more convenient because the saved environment is restored
after exiting the new shell.

<pre>
bash
umask 0022
export ARCH=arm CROSS_COMPILE=${CROSSDEV_TARGET}-
export PS1="($ARCH) $PS1"
</pre>

Now a default configuration for the kernel will be created.

<pre>
make omap2plus_defconfig
</pre>

A lot of configuration must be done to make the kernel work. To ease this use
[[Cross Install Gentoo kernel-config|kernel-config]] which will configure a running
kernel for the Pandora. It uses the name "pherkad" as computer name. Change
this to any name you like in the config file. Calling oldconfig might be
necessary if "kernel-config" is too old for the current gta04-kernel.

<pre>
cp ../kernel-config .config
make oldconfig
make menuconfig
</pre>

In "General setup/Local version" change "-pherkad" to any name you like. But
use "-" as prefix.

Build the kernel and the device tree "omap3-pandora-600mhz.dtb". Pandora users
with 1 GHz units can use "omap3-pandora-1ghz.dts". Use as much CPU cores as you
have for the compiling process.

<pre>
export CPUS="$(grep processor /proc/cpuinfo | wc -l)"
make -j$CPUS zImage
make -j$CPUS modules
make omap3-pandora-600mhz.dtb
</pre>

Convert the kernel into an image for the U-Boot loader. Use any name you
like for "Linux-pherkad".

<pre>
mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008000 -n \
'Linux-pherkad' -d arch/arm/boot/zImage arch/arm/boot/uImage
</pre>

Generate a "boot.scr" file which loads the kernel image and the correct device
tree.

Keep an eye to the bootargs. It uses the following commands:

* Start the systemd as init process: "init=/lib/systemd/systemd".
* Be quiet: "quiet". This can be removed while development.
* Show a splash screen: "splash". There is currently no splash screen, so this
* Use the root file system at: "root=/dev/mmcblk0p2". Take care to use the same partition as described below.
* Use Ext 4 root file system: "rootfstype=ext4".
* Wait for root file system: "rootwait".
* Mount initially read only: "ro". systemd will remount it later as RW.
* Use the following SWAP partition for hibernation/resume: "resume=/dev/mmcblk0p3". This is currently not used.

The file "boot.txt" will be converted to the boot script "boot.src".

<pre>
cat >boot.txt <<EOF
if itest.w *0x4830a204 == 0x102f
then
setenv devicetree omap3-pandora-1ghz
else
setenv devicetree omap3-pandora-600mhz
fi
setenv defaultdisplay lcd
setenv bootargs "init=/lib/systemd/systemd quiet splash \
root=/dev/mmcblk0p2 rootfstype=ext4 rootwait ro resume=/dev/mmcblk0p3"
ext2load mmc 0:1 0x825f0000 /boot/\${devicetree}.dtb
ext2load mmc 0:1 0x80300000 /boot/uImage-pherkad
bootm 0x80300000 - 0x825f0000
EOF

mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n 'Boot script' \
-d boot.txt boot.scr
</pre>

Exit the kernel build environment.

<pre>
exit
</pre>

=== Install kernel ===

The installation of the kernel into the target directory must be done as root.
Create the "boot" directory for the kernel, device tree and boot script and
copy them to the target directory.

<pre>
su
umask 0022
cp arch/arm/boot/uImage /usr/$CROSSDEV_TARGET/boot/uImage-pherkad
cp .config /usr/$CROSSDEV_TARGET/boot/config-pherkad
cp System.map /usr/$CROSSDEV_TARGET/boot/System.map-pherkad
cp arch/arm/boot/dts/omap3-pandora-600mhz.dtb /usr/$CROSSDEV_TARGET/boot/.
cp boot.scr /usr/$CROSSDEV_TARGET/boot/.
</pre>

Create a link for the boot directory. This is used if the boot directory is an
own partition and the boot loader wants to load the kernel from "boot/uImage-*".
In our case it is not really necessary.

<pre>
(cd /usr/$CROSSDEV_TARGET/boot; ln -s . boot)
</pre>

Install all kernel modules into "target/lib/modules". The symbolic link is for
the cross compiling process to find the kernel configuration.

<pre>
make ARCH=arm CROSS_COMPILE=${CROSSDEV_TARGET}- \
INSTALL_MOD_PATH=/usr/$CROSSDEV_TARGET modules_install

(DIR="$PWD"; cd /usr/$CROSSDEV_TARGET/usr/src; ln -s $DIR linux)
cd ..
</pre>

== Compile system ==

Now it's time to cross compile the whole Gentoo system. The base system is
already installed in the "target" directory. All the binaries there will
be compiled again with our own cross compiler. Also a lot of new packages
(more binaries) will be installed.

=== Prepare cross development system ===

Go to the target and copy all portage configurations from the desktop computer
to the target system, since we want to use the desktop computer system as
base of the Pandora system. This must be done as root.

<pre>
export FROM_DIR="$PWD"
cd /usr/$CROSSDEV_TARGET
</pre>

Edit the "make.conf" file.

<pre>
nano etc/portage/make.conf
</pre>

Change some of the lines there. You might copy some of the contents from
the desktop computer but be sure to have the same CHOST as the CROSSDEV_TARGET.
Especially add or change for the following:

<pre>
CFLAGS="-O2 -pipe -march=armv7-a -mfpu=vfpv3-d16 -mfloat-abi=softfp \
-mfpu=neon -fno-stack-protector -fomit-frame-pointer"
</pre>

or

<pre>
CFLAGS="-O2 -pipe -march=armv7-a -mfpu=vfpv3-d16 -mfloat-abi=hard \
-mfpu=neon -fno-stack-protector -fomit-frame-pointer"
</pre>

<pre>

--binpkg-respect-use=y"

GENTOO_MIRRORS="<enter your mirrors>"
PKGDIR="/usr/portage/packages/${CHOST}"
</pre>

It is recommended to activate the build of binary packages. The cross
compilation will fail to build some packages, so QEmu will build all packages
again. It is not necessary to build good cross compiled packages by QEmu again.
Using binary packages will avoid this and save a lot of time.

To avoid mixing up the binary packages of the desktop comuter and the Pandora
set PKGDIR accordingly. Example: "/usr/portage/packages/${CHOST}"

Also copy and edit some package specific files from your desktop computer.

<pre>
cp -r /etc/portage/package.* etc/portage/.
</pre>

Edit the files in "etc/portage/package.*" and configure the portage tree.

<pre>
sed -i "s/amd64/arm/g" etc/portage/package.keywords/*
rm -r etc/portage/package.keywords/cross*
rm -r etc/portage/package.mask/cross*
rm etc/portage/package.use/cross*
rm etc/portage/package.env/cross*

mkdir etc/portage/repos.conf
cp usr/share/portage/config/repos.conf etc/portage/repos.conf/gentoo.conf
rm -f etc/portage/make.profile

(cd etc/portage && \
ln -s /usr/portage/profiles/default/linux/arm/17.0/armv7a/desktop make.profile)
</pre>

Copy the world file from the desktop computer and remove all packages which
should not be installed on the Pandora system.

<pre>
cp /var/lib/portage/world var/lib/portage/world
nano var/lib/portage/world
</pre>

=== Prepare cross-compilation and QEmu environment ===

A lot of packages will fail but we will keep going the emerge process and
compile the failed packages again with QEmu.

But first update the compiler tools in the target system. They will be needed
later in the QEmu environment. If they fail here, try to do it in the QEmu
part.

Copy the static QEmu binary to the target system and set up portage for the
target system.

<pre>
cp /usr/bin/qemu-arm usr/bin/.
mkdir -p usr/portage
touch usr/portage/.keep
</pre>

Do some standard setup for the target system. Copy some personal configurations
to the root account.

<pre>
cp -L /etc/resolv.conf etc/.
cp -r etc/skel/. root/.

cp /root/.bashrc /root/.dir_colors /root/.screenrc /root/.toprc \
/root/.xsession root/.
</pre>

Some nice tools like htop are worth to install them on the Pandora.

<pre>
mkdir -m0700 root/.config
cp -r /root/.config/htop root/.config/.
</pre>

To access the root account with ssh, copy its configuration. This copies the
"id_*" files, also. Don't do this if you deliberately take care about security.

<pre>
cp -r /root/.ssh/. root/.ssh/.
</pre>

=== Start cross compilation ===

Set up a cross compilation environment (use a third shell instance).

<pre>
bash
export CBUILD=x86_64-pc-linux-gnu
export CHOST=$CROSSDEV_TARGET
export ROOT=$PWD
export PORTAGE_CONFIGROOT=$ROOT
export PS1="($CHOST) $PS1"
</pre>

Try to cross compile all packages.

<pre>
$CHOST-emerge -a binutils glibc linux-headers gcc
$CHOST-emerge -a linux-firmware
$CHOST-emerge -ae @world
</pre>

If one of them fails, save the resume list.

<pre>
$CHOST-emerge -p --resume | grep "^\[[eb].*\]" | grep -ve "^\[blocks" | \
cut -b 18- | cut -d " " -f1 | awk '{ print("=" $0); }' >tmp/packages.txt
</pre>

Now go to "Continue cross-compilation with QEmu".

=== Continue cross-compilation with QEmu ===

Enter the chroot environment and emerge the failed package again (the first one
in the packages.txt file).

The portage tree will be mounted into the target system.

In the chroot environment it might be necessary to switch the compiler. Check
if the same version of gcc is used than the cross compiler with
"gcc-config -l". Set the correct version before starting "emerge".

<pre>
mkdir -p $PWD/run/systemd/resolve
cp /run/systemd/resolve/resolv.conf $PWD/run/systemd/resolve/.
mount --rbind /proc $PWD/proc
mount --make-rslave $PWD/proc
mount --rbind /sys $PWD/sys
mount --make-rslave $PWD/sys
mount --rbind /dev $PWD/dev
mount --make-rslave $PWD/dev
mount --rbind /usr/portage $PWD/usr/portage
chroot $PWD /bin/bash
unset CBUILD CHOST ROOT PORTAGE_CONFIGROOT
env-update
source /etc/profile
cd
source ./.bashrc
export PS1="(chroot) $PS1"
emerge -aB1 $(head -1 /tmp/packages.txt)
exit
umount -l usr/portage
umount -l dev sys proc
</pre>

After fixing the failed package(s), continue with the cross compiler.

<pre>
cat tmp/packages.txt | xargs $CHOST-emerge -1
</pre>

If one of them fails again, save the resume list.

<pre>
$CHOST-emerge -p --resume | grep "^\[[eb].*\]" | grep -ve "^\[blocks" | \
cut -b 18- | cut -d " " -f1 | awk '{ print("=" $0); }' >tmp/packages.txt
</pre>

*Go back to "Continue cross-compilation with QEmu" until all packages are merged
successfully.*

Remove some leftover temporary files.

<pre>
rm -rf /var/tmp/portage/* /usr/$CROSSDEV_TARGET/var/tmp/portage/* \
/usr/$CROSSDEV_TARGET/tmp/packages.txt
</pre>

== Fix lib64-problem ==

Some cross compiled packages install their libraries into the "lib64" directory.
This is not used on the Pandora. So we have to copy all contents from "lib64"
to "lib" and set a link for "lib64".

<pre>
rsync -avc usr/lib64/. usr/lib/.
rm -rf usr/lib64
(cd usr && ln -s lib lib64)
</pre>

== Configure system ==

Set the key map for Pandora in the console and, as usual in Gentoo,
configure the target system.

Use to make the Pandora keyboard work on the console.
([[Cross Install Gentoo Keymap-pandora.map|keymap-pandora.map]])

And disable the suspend mode for handling the lid switch (this does
currently not work).

<pre>
cp "$FROM_DIR/keymap-pandora.map" etc/.
chmod 644 etc/keymap-pandora.map
echo >etc/vconsole.conf "KEYMAP=/etc/keymap-pandora.map"
echo >>etc/vconsole.conf "FONT=eurlatgr"
sed -i 's/#HandleLidSwitch=suspend/HandleLidSwitch=ignore/g' etc/systemd/logind.conf
</pre>

Set up the mount table. Every line in "etc/fstab" will be commented out and
new entries added. The file system labels are used to mount the partitions.

<pre>
sed -ie "s,^/,#/,g" etc/fstab

cat >>etc/fstab <<EOF
LABEL=phlnx_boot /boot ext2 noatime 1 2
LABEL=phlnx_root / ext4 errors=remount-ro,noatime 1 1
LABEL=phlnx_home /home ext4 noatime,nodev,nosuid 1 2
EOF
</pre>

Enter the chroot environment again.

<pre>
mount --rbind /proc $PWD/proc
mount --make-rslave $PWD/proc
mount --rbind /sys $PWD/sys
mount --make-rslave $PWD/sys
mount --rbind /dev $PWD/dev
mount --make-rslave $PWD/dev
mount --rbind /usr/portage $PWD/usr/portage
chroot $PWD /bin/bash
unset CBUILD CHOST ROOT PORTAGE_CONFIGROOT
env-update
source /etc/profile
cd
source ./.bashrc
export PS1="(chroot) $PS1"
</pre>

Set a password for root.

<pre>
passwd
</pre>

Update the configuration files and read/clear all news from portage.

<pre>
dispatch-conf
eselect news list
eselect news read
eselect news purge
</pre>

Enter the time zone and generate the locale info you want (example: enable all
lines with en_US and de_DE).

<pre>
echo "Europe/Berlin" >/etc/timezone
emerge --config sys-libs/timezone-data
nano -w /etc/locale.gen
locale-gen
</pre>

Use en_US.utf8 (entry #9) as locale.

<pre>
eselect locale list
eselect locale set 9
</pre>

Set up mount table, the machine ID and host name.

<pre>
ln -sf /proc/self/mounts /etc/mtab
systemd-machine-id-setup
echo >/etc/machine-info "PRETTY_HOSTNAME=Pherkad"
echo >/etc/hostname "pherkad"
ln -snf /run/systemd/resolve/resolv.conf /etc/resolv.conf
systemctl enable systemd-resolved.service
</pre>

Exit the chroot environment.

<pre>
exit
umount -l usr/portage
umount -l dev sys proc
</pre>

Remove the QEmu binary. It is not used anymore.

<pre>
rm usr/bin/qemu-arm
</pre>

Also remove some leftovers from the cross compiler and the link to our kernel
sources.

<pre>
rm -f etc/portage/profile/package.provided
rm -f sys-include
rm -f usr/src/linux
</pre>

Copy back the target system and restore the previous cross compiler state.

<pre>
cd "$FROM_DIR"
mkdir $CROSSDEV_TARGET
rsync -a /usr/$CROSSDEV_TARGET/. $CROSSDEV_TARGET/.
rm -rf /usr/$CROSSDEV_TARGET
tar -xpjf ${CROSSDEV_TARGET}-saved.tar.bz2 -C /usr
rm ${CROSSDEV_TARGET}-saved.tar.bz2
</pre>

Exit the root shell.

<pre>
exit
</pre>

= Update system =

To update the system, use a similar approach as in the cross compilation phase.
Define CROSSDEV_TARGET as in "Install cross compiling system".

== Start cross-compilation ==

Set up a cross compilation environment (become root and use a second shell
instance again).

<pre>
cd CrossDev
su
umask 0022
tar -cpjf ${CROSSDEV_TARGET}-saved.tar.bz2 -C /usr $CROSSDEV_TARGET
rm -rf /usr/$CROSSDEV_TARGET
mkdir /usr/$CROSSDEV_TARGET
rsync -a $CROSSDEV_TARGET/. /usr/$CROSSDEV_TARGET/.
exit

= Create SD-card partitions phlnx_boot/root/swap/home =

Finally the target system is done. Now it's time to copy it to the Pandora.

== Pandora ==

It's recommended to partition the SD-card for the target system on the Pandora.
Otherwise the boot loader might refuse to work.

Insert the SD-card in the left slot (mmcblk0) and unmount it if necessary.

Create the following partitions:

* A boot partition (ext2).
* A root partition which will contain the target system (at least 4 GB).
* A home partition which we can use later.
* A SWAP partition which we can use later.

<pre>
sudo -s

/sbin/fdisk /dev/mmcblk0
Create new DOS partition label: o
Create new partition: n p 1 Return +8M
Create new partition: n p 2 Return +4G
Create new partition: n p 3 Return +1G
Change partition type: t 3 82 (Linux swap)
Create new partition: n p Return Return
Write all changes: w

/sbin/mkfs.ext2 -FL phlnx_boot /dev/mmcblk0p1
/sbin/mkfs.ext4 -FL phlnx_root -O ^has_journal /dev/mmcblk0p2
/sbin/mkswap -L phlnx_swap /dev/mmcblk0p3
/sbin/mkfs.ext4 -FL phlnx_home -O ^has_journal /dev/mmcblk0p4
exit
</pre>

= Option #1: Copy target system to SD-card =

One of the possibilities to copy the target system to the SD-card on the Pandora
is to use a USB cable connecting the Pandora to the desktop computer.

It's also possible to copy it via the WiFi network (see below).

== Pandora ==

Connect the Pandora via USB to the desktop computer. Insert the SD-card in the
left slot (mmcblk0). Use menu "System/SD-Mass Storage" to access partition
"phlnx_root".

== Desktop computer ==

Mount the root partition and copy the target system. Use the correct "/dev/sd*".

<pre>
su
mkdir /tmp/mnt
mount /dev/sdc /tmp/mnt
mkdir -p /tmp/mnt/boot
touch /tmp/mnt/boot/.keep
mkdir -p /tmp/mnt/home
touch /tmp/mnt/home/.keep

rsync -av --delete --exclude lost+found --exclude /boot \
CrossDev/$CROSSDEV_TARGET/. /tmp/mnt/.

umount /tmp/mnt
</pre>

== Pandora ==

Use "System/SD-Mass Storage" again to access phlnx_boot.

== Desktop computer ==

Mount the boot partition and copy boot directory of the target system.

<pre>
mount /dev/sdc /tmp/mnt
rm -f /tmp/mnt/uImage-pherkad

rsync -av --delete --exclude lost+found \
CrossDev/$CROSSDEV_TARGET/boot/. /tmp/mnt/.

umount /tmp/mnt
rmdir /tmp/mnt
exit
</pre>

== Pandora ==

End SD-Mass Storage.

= Option #2: Copy target system to SD-card via WiFi network =

== Pandora ==

Copy all files from the desktop computer to the SD-card partitions. Use the
same CROSSDEV_TARGET and FROM_DIR environment settings as on the desktop
computer.

<pre>
sudo -s
export REMOTE=mizar.spdns.de
export FROM_DIR=/home/jgeiss/Data/Systems/Pandora/Pherkad/Linux/Gentoo/CrossDev
export CROSSDEV_TARGET=armv7a-hardfloat-linux-gnueabi

mkdir -p /media/phlnx_root/boot
touch /media/phlnx_root/boot/.keep

rsync -av --numeric-ids --delete --exclude lost+found --exclude /boot \
$REMOTE:$FROM_DIR/$CROSSDEV_TARGET/. /media/phlnx_root/.

rsync -av --delete --exclude lost+found \
$REMOTE:$FROM_DIR/$CROSSDEV_TARGET/boot/. /media/phlnx_boot/.

exit
</pre>

= Boot the new system =

Reboot the Pandora and hold the right shoulder button until the boot menu
appears.

'''Sometimes it is necessary to switch off the Pandora for 10-60 seconds.'''

Choose "boot from SD1:1".

It the boot works well, login as root and play around.

== Optional: USB-networking ==

To use networking to the desktop computer via USB cable, execute the
following commands on both systems.

=== Pandora ===

<pre>
modprobe g_ether
ifconfig usb0 192.168.129.3 netmask 255.255.255.0
route add default gw 192.168.129.2
systemctl start sshd
</pre>

=== Desktop computer ===

Configure the corresponding network interface.

<pre>
ifconfig enp0s20u1u1 192.168.129.2 netmask 255.255.255.0
</pre>

Now you should be able to connect to the Pandora.

<pre>
ssh root@192.168.129.3
</pre>

== Shutdown Pandora ==

To shutdown the Pandora system enter the following command.

<pre>
systemctl poweroff
</pre>

= Open issues =

The following things are currently not working and need to be implemented/fixed:

* WiFi interface is missing
* twl: not initialized
* omapfb omapfb: no displays, failed to setup omapfb
* omap2_set_init_voltage: unable to find boot up OPP vor ...
* __nand_correct_data: uncorrectable ECC error
* Buffer I/O error on dev mtdblock0, logical block 0, async page read
* Kernel panic at system shutdown

Cross Install Gentoo

2018-06-15T12:58:45Z

Jgeiss: Removed patch for kernel bcause its now in the gta04-kernel tree.

= Introduction =

These instructions are for installing a recent Gentoo Linux on the OpenPandora
handheld console. The system will be installed and booted from a SD-card. The
Gentoo Linux will be cross-compiled on another desktop computer also running
Gentoo Linux.

It is not necessary to follow all instructions exactly. Some of them can be
changed to your own needs.

'''The system currently supports only the text console and no X11 or sound.'''
'''Also a lot of features are missing.''' See "Open issues" at the end.

== Prerequisites ==

These instructions assume the following prerequisites:

* Good knowledge in Gentoo Linux.
* A desktop computer running Gentoo Linux. Other Linux is, of course, also possible but requires proper adaption of these instructions.
* An OpenPandora handheld console.
* A SD-card with least 8 GB size.
* A USB cable to connect the Pandora to the desktop computer.

== Improvement ==

Due to the constant changes of the Linux kernel, GNU software, etc. this
document will be outdated very quick. To avoid this, help is always appreciated
improving this document. If you can update, improve, add or complete this
document, don't hesitate to do so.

= Prepare/install cross compile system =

To perform the cross-compilation a cross compiler and QEmu must be installed
on the desktop computer. QEmu will help a lot for compiling packages which
will not properly cross compile.

== Install cross compiling system ==

For compiling software for an ARM controller a cross compiler must be installed.

We can use ARMv7 using either soft float (armv7a-softfp-linux-gnueabi) or hard
float (armv7a-hardfloat-linux-gnueabi).

<pre>export CROSSDEV_TARGET=armv7a-softfp-linux-gnueabi</pre>

or

<pre>export CROSSDEV_TARGET=armv7a-hardfloat-linux-gnueabi</pre>

The additional portage tree in "/usr/local/portage-crossdev" will hold all
information for emerging the cross build system (cross compiler and tools).

To prepare emerging a cross compiler, execute the following commands.

<pre>
su
umask 0022

emerge -av crossdev

mkdir -p /usr/local/portage-crossdev/{profiles,metadata}

echo 'local-crossdev' >/usr/local/portage-crossdev/profiles/repo_name
echo 'masters = gentoo' >/usr/local/portage-crossdev/metadata/layout.conf
echo 'thin-manifests = true' >>/usr/local/portage-crossdev/metadata/layout.conf
chown -R portage:portage /usr/local/portage-crossdev

echo '[local-crossdev]' >/etc/portage/repos.conf/crossdev.conf

echo 'location = /usr/local/portage-crossdev' \
>>/etc/portage/repos.conf/crossdev.conf

echo 'priority = 10' >>/etc/portage/repos.conf/crossdev.conf
echo 'masters = gentoo' >>/etc/portage/repos.conf/crossdev.conf
echo 'auto-sync = no' >>/etc/portage/repos.conf/crossdev.conf
</pre>

The portage tree for emerging the cross build system is set up. Now we have to
find out which versions of the cross build components are about to be installed.
The target system will get binutils, gcc, glibc and linux-headers of a certain
version. The same version should be installed in the cross build system.

<pre>
export BINUTILS_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-devel/binutils/binutils-*.ebuild | tail -1 | \
awk 'match($0, ".*/binutils-(.*).ebuild", v) { print(v[1]); }')

export GCC_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-devel/gcc/gcc-*.ebuild | tail -1 | \
awk 'match($0, ".*/gcc-(.*).ebuild", v) { print(v[1]); }')

export GLIBC_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-libs/glibc/glibc-*.ebuild | tail -1 | \
awk 'match($0, ".*/glibc-(.*).ebuild", v) { print(v[1]); }')

export LINUX_HEADERS_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-kernel/linux-headers/linux-headers-*.ebuild | tail -1 | \
awk 'match($0, ".*/linux-headers-(.*).ebuild", v) { print(v[1]); }')
</pre>

Now emerge the cross compiler.

<pre>
crossdev --binutils $BINUTILS_VER --gcc $GCC_VER --libc $GLIBC_VER \
--kernel $LINUX_HEADERS_VER --target $CROSSDEV_TARGET
</pre>

== Install QEmu ==

A lot of packages will not cross compile properly. QEmu will help for these
packages. Install it to emulate an ARM controller.

Edit /etc/portage/make.conf.

<pre>
nano /etc/portage/make.conf
</pre>

And add the following lines.

<pre>
QEMU_SOFTMMU_TARGETS=""
QEMU_USER_TARGETS="arm"
</pre>

Also enable the use flag static-user. This builds QEmu as static binary.
QEmu will be used later in a chroot environment of an ARM controller and will
be unable to access needed shared libraries. So it must contain all these
libraries by building it in a static way.

<pre>
euse -E static-user
</pre>

All the needed libraries for QEmu must also be available as library archive
(static libs). Emerging QEmu will request to emerge these libraries as
static variants, also. Create and add these libraries in the file
"/etc/portage/package.use/qemu". Look which libraries are needed.

<pre>
emerge -pv qemu
</pre>

And add them with the use flag static-libs. Here is an Example:

<pre>
>=net-misc/curl-7.53.0 static-libs
>=sys-apps/attr-2.4.47-r2 static-libs
>=media-libs/libsdl-1.2.15-r9 static-libs
>=sys-apps/dtc-1.4.1 static-libs
>=app-arch/bzip2-1.0.6-r7 static-libs
>=x11-libs/pixman-0.34.0 static-libs
>=dev-libs/libpcre-8.40-r1 static-libs
>=sys-libs/libseccomp-2.3.0 static-libs
>=net-fs/libnfs-1.9.7 static-libs
>=dev-libs/cyrus-sasl-2.1.26-r9 static-libs
>=dev-libs/gmp-6.1.0 static-libs
>=dev-libs/libaio-0.3.110 static-libs
>=sys-fs/xfsprogs-4.5.0 static-libs
>=sys-libs/zlib-1.2.11 static-libs
>=media-libs/libjpeg-turbo-1.5.0 static-libs
>=sys-libs/libcap-ng-0.7.8 static-libs
>=dev-libs/openssl-1.0.2k static-libs
>=dev-libs/glib-2.50.3-r1 static-libs
>=virtual/jpeg-0-r2:0 static-libs
>=media-libs/libpng-1.6.27 static-libs
>=sys-libs/ncurses-6.0-r1 static-libs
</pre>

Emerge QEmu.

<pre>
emerge qemu
udevadm trigger -c add /dev/kvm
</pre>

QEmu will execute ARM binaries on the desktop computer as if it would have an
ARM controller. To achieve this, register foreign binaries and start the
systemd service.

<pre>
ln -s /usr/share/qemu/binfmt.d/qemu.conf /etc/binfmt.d/qemu.conf
systemctl start systemd-binfmt
</pre>

Now our desktop computer is able to execute ARM binaries as well as his own
binaries.

== Install GIT ==

To get the kernel sources, GIT will be needed. Emerge it.

<pre>
emerge git
</pre>

Exit the root shell.

<pre>
exit
</pre>

Now the cross build system is ready to compile a Gentoo Linux for the Pandora.

= Install system =

== Prepare target file system ==

To build the system for the Pandora about 10 GB disk space is needed. Create a
directory "CrossDev" to store all data there.

<pre>
mkdir CrossDev
cd CrossDev
</pre>

In this directory two more directories will be created:

* One to store and build the Linux kernel.
* Another will store the whole system for the Pandora including QEmu which is not really a part of the system for Pandora, but it is needed as long as the building process runs.
* Some files and archives.

First get the Gentoo base system "stage3-armv7a-*.tar.bz2". Download it from
a suitable mirror of the Gentoo distribution. See
https://www.gentoo.org/downloads/mirrors for a list of mirrors.

Go to the directory "releases/arm/autobuilds". According to your target, enter

* "current-stage3-armv7a" for soft float (armv7a-softfp-linux-gnueabi),
* "current-stage3-armv7a_hardfp" for hard float (armv7a-hardfloat-linux-gnueabi).

There is a stage 3 file for ARMv7. Download this archive.

Example:

<pre>
wget http://mirror.eu.oneandone.net/linux/distributions/gentoo/gentoo/\
releases/arm/autobuilds/current-stage3-armv7a/stage3-armv7a-20161129.tar.bz2
</pre>

or

<pre>
wget http://mirror.eu.oneandone.net/linux/distributions/gentoo/gentoo/\
releases/arm/autobuilds/current-stage3-armv7a_hardfp/\
stage3-armv7a_hardfp-20161129.tar.bz2
</pre>

As long as we are cross compiling, we use "/usr/$CROSSDEV_TARGET" as working
directory. The cross compiler looks for libraries there and uses many references
to this directory. That's why "/usr/$CROSSDEV_TARGET" will be saved, so it can
be restored after the build.

<pre>
su
umask 0022
tar -cpjf ${CROSSDEV_TARGET}-saved.tar.bz2 -C /usr $CROSSDEV_TARGET
</pre>

Unpack the stage 3 archive into "/usr/$CROSSDEV_TARGET".

<pre>
tar --xattrs --numeric-owner -xpjf stage3-*.tar.bz2 -C /usr/$CROSSDEV_TARGET
</pre>

Sometimes there is a lot of garbage in the "tmp" directory. Remove it.

<pre>
rm -rf /usr/$CROSSDEV_TARGET/tmp/*
</pre>

Exit the root shell and go back to our working directory.

<pre>
exit
</pre>

== Compile/install kernel ==

The standard Gentoo kernel will not run on the Pandora (or, at least, takes too
much effort to make it run), so download a current kernel from
https://goldelico.com using GIT.

=== Download kernel ===

Download the kernel with GIT.

<pre>
git clone git://git.goldelico.com/gta04-kernel.git
cd gta04-kernel
</pre>

=== Compile kernel ===

Prepare an environment to cross compile the kernel. First call another shell
instance for saving the current environment. This instance is not really
necessary but it is more convenient because the saved environment is restored
after exiting the new shell.

<pre>
bash
umask 0022
export ARCH=arm CROSS_COMPILE=${CROSSDEV_TARGET}-
export PS1="($ARCH) $PS1"
</pre>

Now a default configuration for the kernel will be created.

<pre>
make omap2plus_defconfig
</pre>

A lot of configuration must be done to make the kernel work. To ease this use
[[Cross Install Gentoo kernel-config|kernel-config]] which will configure a running
kernel for the Pandora. It uses the name "pherkad" as computer name. Change
this to any name you like in the config file. Calling oldconfig might be
necessary if "kernel-config" is too old for the current gta04-kernel.

<pre>
cp ../kernel-config .config
make oldconfig
make menuconfig
</pre>

In "General setup/Local version" change "-pherkad" to any name you like. But
use "-" as prefix.

Build the kernel and the device tree "omap3-pandora-600mhz.dtb". Pandora users
with 1 GHz units can use "omap3-pandora-1ghz.dts". Use as much CPU cores as you
have for the compiling process.

<pre>
export CPUS="$(grep processor /proc/cpuinfo | wc -l)"
make -j$CPUS zImage
make -j$CPUS modules
make omap3-pandora-600mhz.dtb
</pre>

Convert the kernel into an image for the U-Boot loader. Use any name you
like for "Linux-pherkad".

<pre>
mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008000 -n \
'Linux-pherkad' -d arch/arm/boot/zImage arch/arm/boot/uImage
</pre>

Generate a "boot.scr" file which loads the kernel image and the correct device
tree.

Keep an eye to the bootargs. It uses the following commands:

* Start the systemd as init process: "init=/lib/systemd/systemd".
* Be quiet: "quiet". This can be removed while development.
* Show a splash screen: "splash". There is currently no splash screen, so this
* Use the root file system at: "root=/dev/mmcblk0p2". Take care to use the same partition as described below.
* Use Ext 4 root file system: "rootfstype=ext4".
* Wait for root file system: "rootwait".
* Mount initially read only: "ro". systemd will remount it later as RW.
* Use the following SWAP partition for hibernation/resume: "resume=/dev/mmcblk0p3". This is currently not used.

The file "boot.txt" will be converted to the boot script "boot.src".

<pre>
cat >boot.txt <<EOF
if itest.w *0x4830a204 == 0x102f
then
setenv devicetree omap3-pandora-1ghz

EOF

mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n 'Boot script' \
-d boot.txt boot.scr
</pre>

Exit the kernel build environment.

<pre>
exit
</pre>

=== Install kernel ===

The installation of the kernel into the target directory must be done as root.
Create the "boot" directory for the kernel, device tree and boot script and
copy them to the target directory.

<pre>
su
umask 0022
cp arch/arm/boot/uImage /usr/$CROSSDEV_TARGET/boot/uImage-pherkad
cp .config /usr/$CROSSDEV_TARGET/boot/config-pherkad
cp System.map /usr/$CROSSDEV_TARGET/boot/System.map-pherkad
cp arch/arm/boot/dts/omap3-pandora-600mhz.dtb /usr/$CROSSDEV_TARGET/boot/.
cp boot.scr /usr/$CROSSDEV_TARGET/boot/.
</pre>

Create a link for the boot directory. This is used if the boot directory is an
own partition and the boot loader wants to load the kernel from "boot/uImage-*".
In our case it is not really necessary.

<pre>
(cd /usr/$CROSSDEV_TARGET/boot; ln -s . boot)
</pre>

Install all kernel modules into "target/lib/modules". The symbolic link is for
the cross compiling process to find the kernel configuration.

<pre>
make ARCH=arm CROSS_COMPILE=${CROSSDEV_TARGET}- \
INSTALL_MOD_PATH=/usr/$CROSSDEV_TARGET modules_install

(DIR="$PWD"; cd /usr/$CROSSDEV_TARGET/usr/src; ln -s $DIR linux)
cd ..
</pre>

== Compile system ==

Now it's time to cross compile the whole Gentoo system. The base system is
already installed in the "target" directory. All the binaries there will
be compiled again with our own cross compiler. Also a lot of new packages
(more binaries) will be installed.

=== Prepare cross development system ===

Go to the target and copy all portage configurations from the desktop computer
to the target system, since we want to use the desktop computer system as
base of the Pandora system. This must be done as root.

<pre>
export FROM_DIR="$PWD"
cd /usr/$CROSSDEV_TARGET
</pre>

Edit the "make.conf" file.

<pre>
nano etc/portage/make.conf
</pre>

Change some of the lines there. You might copy some of the contents from
the desktop computer but be sure to have the same CHOST as the CROSSDEV_TARGET.
Especially add or change for the following:

<pre>
CFLAGS="-O2 -pipe -march=armv7-a -mfpu=vfpv3-d16 -mfloat-abi=softfp \
-mfpu=neon -fno-stack-protector"
</pre>

or

<pre>
CFLAGS="-O2 -pipe -march=armv7-a -mfpu=vfpv3-d16 -mfloat-abi=hard \
-mfpu=neon -fno-stack-protector"
</pre>

PKGDIR="/usr/portage/packages/${CHOST}"
</pre>

It is recommended to activate the build of binary packages. The cross
compilation will fail to build some packages, so QEmu will build all packages
again. It is not necessary to build good cross compiled packages by QEmu again.
Using binary packages will avoid this and save a lot of time.

To avoid mixing up the binary packages of the desktop comuter and the Pandora
set PKGDIR accordingly. Example: "/usr/portage/packages/${CHOST}"

Also copy and edit some package specific files from your desktop computer.

<pre>
cp -r /etc/portage/package.* etc/portage/.
</pre>

Edit the files in "etc/portage/package.*" and configure the portage tree.

<pre>
sed -i "s/amd64/arm/g" etc/portage/package.keywords/*
rm -r etc/portage/package.keywords/cross*
rm -r etc/portage/package.mask/cross*
rm etc/portage/package.use/cross*
rm etc/portage/package.env/cross*

mkdir etc/portage/repos.conf
cp usr/share/portage/config/repos.conf etc/portage/repos.conf/gentoo.conf
rm -f etc/portage/make.profile

(cd etc/portage && \
ln -s /usr/portage/profiles/default/linux/arm/13.0/armv7a/desktop make.profile)
</pre>

Copy the world file from the desktop computer and remove all packages which
should not be installed on the Pandora system.

<pre>
cp /var/lib/portage/world var/lib/portage/world
nano var/lib/portage/world
</pre>

=== Prepare cross-compilation and QEmu environment ===

A lot of packages will fail but we will keep going the emerge process and
compile the failed packages again with QEmu.

But first update the compiler tools in the target system. They will be needed
later in the QEmu environment. If they fail here, try to do it in the QEmu
part.

Copy the static QEmu binary to the target system and set up portage for the
target system.

<pre>
cp /usr/bin/qemu-arm usr/bin/.
mkdir -p usr/portage
touch usr/portage/.keep
</pre>

Do some standard setup for the target system. Copy some personal configurations
to the root account.

<pre>
cp -L /etc/resolv.conf etc/.
cp -r etc/skel/. root/.

cp /root/.bashrc /root/.dir_colors /root/.screenrc /root/.toprc \
/root/.xsession root/.
</pre>

Some nice tools like htop are worth to install them on the Pandora.

<pre>
mkdir -m0700 root/.config
cp -r /root/.config/htop root/.config/.
</pre>

To access the root account with ssh, copy its configuration. This copies the
"id_*" files, also. Don't do this if you deliberately take care about security.

<pre>
cp -r /root/.ssh/. root/.ssh/.
</pre>

=== Start cross compilation ===

Set up a cross compilation environment (use a third shell instance).

<pre>
bash
export CBUILD=x86_64-pc-linux-gnu
export CHOST=$CROSSDEV_TARGET
export ROOT=$PWD
export PORTAGE_CONFIGROOT=$ROOT
export PS1="($CHOST) $PS1"
</pre>

Try to cross compile all packages.

<pre>
$CHOST-emerge -a binutils glibc linux-headers gcc
$CHOST-emerge -a linux-firmware
$CHOST-emerge -ae @world
</pre>

If one of them fails, save the resume list.

<pre>
$CHOST-emerge -p --resume | grep "^\[[eb].*\]" | grep -ve "^\[blocks" | \
cut -b 18- | cut -d " " -f1 | awk '{ print("=" $0); }' >tmp/packages.txt
</pre>

Now go to "Continue cross-compilation with QEmu".

=== Continue cross-compilation with QEmu ===

Enter the chroot environment and emerge the failed package again (the first one
in the packages.txt file).

The portage tree will be mounted into the target system.

In the chroot environment it might be necessary to switch the compiler. Check
if the same version of gcc is used than the cross compiler with
"gcc-config -l". Set the correct version before starting "emerge".

<pre>
mkdir -p $PWD/run/systemd/resolve
cp /run/systemd/resolve/resolv.conf $PWD/run/systemd/resolve/.
mount --rbind /proc $PWD/proc
mount --make-rslave $PWD/proc
mount --rbind /sys $PWD/sys
mount --make-rslave $PWD/sys
mount --rbind /dev $PWD/dev
mount --make-rslave $PWD/dev
mount --rbind /usr/portage $PWD/usr/portage
chroot $PWD /bin/bash
unset CBUILD CHOST ROOT PORTAGE_CONFIGROOT
env-update
source /etc/profile
cd
source ./.bashrc
export PS1="(chroot) $PS1"
emerge -aB1 $(head -1 /tmp/packages.txt)
exit
umount -l usr/portage
umount -l dev sys proc
</pre>

After fixing the failed package(s), continue with the cross compiler.

<pre>
cat tmp/packages.txt | xargs $CHOST-emerge -1
</pre>

If one of them fails again, save the resume list.

<pre>
$CHOST-emerge -p --resume | grep "^\[[eb].*\]" | grep -ve "^\[blocks" | \
cut -b 18- | cut -d " " -f1 | awk '{ print("=" $0); }' >tmp/packages.txt
</pre>

*Go back to "Continue cross-compilation with QEmu" until all packages are merged
successfully.*

Remove some leftover temporary files.

<pre>
rm -rf /var/tmp/portage/* /usr/$CROSSDEV_TARGET/var/tmp/portage/* \
/usr/$CROSSDEV_TARGET/tmp/packages.txt
</pre>

== Fix lib64-problem ==

Some cross compiled packages install their libraries into the "lib64" directory.
This is not used on the Pandora. So we have to copy all contents from "lib64"
to "lib" and set a link for "lib64".

<pre>
rsync -avc usr/lib64/. usr/lib/.
rm -rf usr/lib64
(cd usr && ln -s lib lib64)
</pre>

== Configure system ==

Set the key map for Pandora in the console and, as usual in Gentoo,
configure the target system.

Use to make the Pandora keyboard work on the console.
([[Cross Install Gentoo Keymap-pandora.map|keymap-pandora.map]])

And disable the suspend mode for handling the lid switch (this does
currently not work).

<pre>
cp "$FROM_DIR/keymap-pandora.map" etc/.
chmod 644 etc/keymap-pandora.map
echo >etc/vconsole.conf "KEYMAP=/etc/keymap-pandora.map"
echo >>etc/vconsole.conf "FONT=eurlatgr"
sed -i 's/#HandleLidSwitch=suspend/HandleLidSwitch=ignore/g' etc/systemd/logind.conf
</pre>

Set up the mount table. Every line in "etc/fstab" will be commented out and
new entries added. The file system labels are used to mount the partitions.

<pre>
sed -ie "s,^/,#/,g" etc/fstab

cat >>etc/fstab <<EOF
LABEL=phlnx_boot /boot ext2 noatime 1 2
LABEL=phlnx_root / ext4 errors=remount-ro,noatime 1 1
LABEL=phlnx_home /home ext4 noatime,nodev,nosuid 1 2
EOF
</pre>

Enter the chroot environment again.

<pre>
mount --rbind /proc $PWD/proc
mount --make-rslave $PWD/proc
mount --rbind /sys $PWD/sys
mount --make-rslave $PWD/sys
mount --rbind /dev $PWD/dev

chroot $PWD /bin/bash
unset CBUILD CHOST ROOT PORTAGE_CONFIGROOT
env-update
source /etc/profile
cd
source ./.bashrc
export PS1="(chroot) $PS1"
</pre>

Set a password for root.

<pre>
passwd
</pre>

Update the configuration files and read/clear all news from portage.

<pre>
dispatch-conf
eselect news list
eselect news read
eselect news purge
</pre>

Enter the time zone and generate the locale info you want (example: enable all
lines with en_US and de_DE).

<pre>
echo "Europe/Berlin" >/etc/timezone
emerge --config sys-libs/timezone-data
nano -w /etc/locale.gen
locale-gen
</pre>

Use en_US.utf8 (entry #9) as locale.

<pre>
eselect locale list
eselect locale set 9
</pre>

Set up mount table, the machine ID and host name.

<pre>
ln -sf /proc/self/mounts /etc/mtab
systemd-machine-id-setup
echo >/etc/machine-info "PRETTY_HOSTNAME=Pherkad"
echo >/etc/hostname "pherkad"
ln -snf /run/systemd/resolve/resolv.conf /etc/resolv.conf
systemctl enable systemd-resolved.service
</pre>

Exit the chroot environment.

<pre>
exit
umount -l usr/portage
umount -l dev sys proc
</pre>

Remove the QEmu binary. It is not used anymore.

<pre>
rm usr/bin/qemu-arm
</pre>

Also remove some leftovers from the cross compiler and the link to our kernel
sources.

<pre>
rm -f etc/portage/profile/package.provided
rm -f sys-include
rm -f usr/src/linux
</pre>

Copy back the target system and restore the previous cross compiler state.

<pre>
cd "$FROM_DIR"
mkdir $CROSSDEV_TARGET
rsync -a /usr/$CROSSDEV_TARGET/. $CROSSDEV_TARGET/.
rm -rf /usr/$CROSSDEV_TARGET
tar -xpjf ${CROSSDEV_TARGET}-saved.tar.bz2 -C /usr
rm ${CROSSDEV_TARGET}-saved.tar.bz2
</pre>

Exit the root shell.

<pre>
exit
</pre>

= Update system =

To update the system, use a similar approach as in the cross compilation phase.
Define CROSSDEV_TARGET as in "Install cross compiling system".

== Start cross-compilation ==

Set up a cross compilation environment (become root and use a second shell
instance again).

<pre>
cd CrossDev
su
umask 0022

= Create SD-card partitions phlnx_boot/root/swap/home =

Finally the target system is done. Now it's time to copy it to the Pandora.

== Pandora ==

It's recommended to partition the SD-card for the target system on the Pandora.
Otherwise the boot loader might refuse to work.

Insert the SD-card in the left slot (mmcblk0) and unmount it if necessary.

Create the following partitions:

* A boot partition (ext2).
* A root partition which will contain the target system (at least 4 GB).
* A home partition which we can use later.
* A SWAP partition which we can use later.

<pre>
sudo -s

/sbin/fdisk /dev/mmcblk0
Create new DOS partition label: o
Create new partition: n p 1 Return +8M
Create new partition: n p 2 Return +4G
Create new partition: n p 3 Return +1G
Change partition type: t 3 82 (Linux swap)
Create new partition: n p Return Return
Write all changes: w

/sbin/mkfs.ext2 -FL phlnx_boot /dev/mmcblk0p1
/sbin/mkfs.ext4 -FL phlnx_root -O ^has_journal /dev/mmcblk0p2

/sbin/mkfs.ext4 -FL phlnx_home -O ^has_journal /dev/mmcblk0p4
exit
</pre>

= Option #1: Copy target system to SD-card =

One of the possibilities to copy the target system to the SD-card on the Pandora
is to use a USB cable connecting the Pandora to the desktop computer.

It's also possible to copy it via the WiFi network (see below).

== Pandora ==

Connect the Pandora via USB to the desktop computer. Insert the SD-card in the
left slot (mmcblk0). Use menu "System/SD-Mass Storage" to access partition
"phlnx_root".

== Desktop computer ==

Mount the root partition and copy the target system. Use the correct "/dev/sd*".

<pre>
su
mkdir /tmp/mnt
mount /dev/sdc /tmp/mnt
mkdir -p /tmp/mnt/boot
touch /tmp/mnt/boot/.keep
mkdir -p /tmp/mnt/home
touch /tmp/mnt/home/.keep

rsync -av --delete --exclude lost+found --exclude /boot \
CrossDev/$CROSSDEV_TARGET/. /tmp/mnt/.

umount /tmp/mnt
</pre>

== Pandora ==

Use "System/SD-Mass Storage" again to access phlnx_boot.

== Desktop computer ==

Mount the boot partition and copy boot directory of the target system.

<pre>
mount /dev/sdc /tmp/mnt
rm -f /tmp/mnt/uImage-pherkad

rsync -av --delete --exclude lost+found \
CrossDev/$CROSSDEV_TARGET/boot/. /tmp/mnt/.

umount /tmp/mnt
rmdir /tmp/mnt
exit
</pre>

== Pandora ==

End SD-Mass Storage.

= Option #2: Copy target system to SD-card via WiFi network =

== Pandora ==

Copy all files from the desktop computer to the SD-card partitions. Use the
same CROSSDEV_TARGET and FROM_DIR environment settings as on the desktop
computer.

<pre>
sudo -s
export REMOTE=mizar.spdns.de
export FROM_DIR=/home/jgeiss/Data/Systems/Pandora/Pherkad/Linux/Gentoo/CrossDev
export CROSSDEV_TARGET=armv7a-hardfloat-linux-gnueabi

mkdir -p /media/phlnx_root/boot
touch /media/phlnx_root/boot/.keep

rsync -av --numeric-ids --delete --exclude lost+found --exclude /boot \
$REMOTE:$FROM_DIR/$CROSSDEV_TARGET/. /media/phlnx_root/.

rsync -av --delete --exclude lost+found \
$REMOTE:$FROM_DIR/$CROSSDEV_TARGET/boot/. /media/phlnx_boot/.

exit
</pre>

= Boot the new system =

Reboot the Pandora and hold the right shoulder button until the boot menu
appears.

'''Sometimes it is necessary to switch off the Pandora for 10-60 seconds.'''

Choose "boot from SD1:1".

It the boot works well, login as root and play around.

== Optional: USB-networking ==

To use networking to the desktop computer via USB cable, execute the
following commands on both systems.

=== Pandora ===

<pre>
modprobe g_ether
ifconfig usb0 192.168.129.3 netmask 255.255.255.0
route add default gw 192.168.129.2
systemctl start sshd
</pre>

=== Desktop computer ===

Configure the corresponding network interface.

<pre>
ifconfig enp0s20u1u1 192.168.129.2 netmask 255.255.255.0
</pre>

Now you should be able to connect to the Pandora.

<pre>
ssh root@192.168.129.3
</pre>

== Shutdown Pandora ==

To shutdown the Pandora system enter the following command.

<pre>
systemctl poweroff
</pre>

= Open issues =

The following things are currently not working and need to be implemented/fixed:

* WiFi interface is missing
* twl: not initialized
* omapfb omapfb: no displays, failed to setup omapfb
* omap2_set_init_voltage: unable to find boot up OPP vor ...
* __nand_correct_data: uncorrectable ECC error
* Buffer I/O error on dev mtdblock0, logical block 0, async page read
* Kernel panic at system shutdown

Cross Install Gentoo

2018-06-10T13:20:56Z

Jgeiss: /* Open issues */

= Cross install Gentoo Linux on Pandora =

== Introduction ==

These instructions are for installing a recent Gentoo Linux on the OpenPandora
handheld console. The system will be installed and booted from a SD-card. The
Gentoo Linux will be cross-compiled on another desktop computer also running
Gentoo Linux.

It is not necessary to follow all instructions exactly. Some of them can be
changed to your own needs.

'''The system currently supports only the text console and no X11 or sound.'''
'''Also a lot of features are missing.''' See "Open issues" at the end.

=== Prerequisites ===

These instructions assume the following prerequisites:

* Good knowledge in Gentoo Linux.
* A desktop computer running Gentoo Linux. Other Linux is, of course, also possible but requires proper adaption of these instructions.
* An OpenPandora handheld console.
* A SD-card with least 8 GB size.
* A USB cable to connect the Pandora to the desktop computer.

=== Improvement ===

Due to the constant changes of the Linux kernel, GNU software, etc. this
document will be outdated very quick. To avoid this, help is always appreciated
improving this document. If you can update, improve, add or complete this
document, don't hesitate to do so.

== Prepare/install cross compile system ==

To perform the cross-compilation a cross compiler and QEmu must be installed
on the desktop computer. QEmu will help a lot for compiling packages which
will not properly cross compile.

=== Install cross compiling system ===

For compiling software for an ARM controller a cross compiler must be installed.

We can use ARMv7 using either soft float (armv7a-softfp-linux-gnueabi) or hard
float (armv7a-hardfloat-linux-gnueabi).

<pre>export CROSSDEV_TARGET=armv7a-softfp-linux-gnueabi</pre>

or

<pre>export CROSSDEV_TARGET=armv7a-hardfloat-linux-gnueabi</pre>

The additional portage tree in "/usr/local/portage-crossdev" will hold all
information for emerging the cross build system (cross compiler and tools).

To prepare emerging a cross compiler, execute the following commands.

<pre>
su
umask 0022

emerge -av crossdev

mkdir -p /usr/local/portage-crossdev/{profiles,metadata}

echo 'local-crossdev' >/usr/local/portage-crossdev/profiles/repo_name
echo 'masters = gentoo' >/usr/local/portage-crossdev/metadata/layout.conf
echo 'thin-manifests = true' >>/usr/local/portage-crossdev/metadata/layout.conf
chown -R portage:portage /usr/local/portage-crossdev

echo '[local-crossdev]' >/etc/portage/repos.conf/crossdev.conf

echo 'location = /usr/local/portage-crossdev' \
>>/etc/portage/repos.conf/crossdev.conf

echo 'priority = 10' >>/etc/portage/repos.conf/crossdev.conf
echo 'masters = gentoo' >>/etc/portage/repos.conf/crossdev.conf
echo 'auto-sync = no' >>/etc/portage/repos.conf/crossdev.conf
</pre>

The portage tree for emerging the cross build system is set up. Now we have to
find out which versions of the cross build components are about to be installed.
The target system will get binutils, gcc, glibc and linux-headers of a certain
version. The same version should be installed in the cross build system.

<pre>
export BINUTILS_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-devel/binutils/binutils-*.ebuild | tail -1 | \
awk 'match($0, ".*/binutils-(.*).ebuild", v) { print(v[1]); }')

export GCC_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-devel/gcc/gcc-*.ebuild | tail -1 | \
awk 'match($0, ".*/gcc-(.*).ebuild", v) { print(v[1]); }')

export GLIBC_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-libs/glibc/glibc-*.ebuild | tail -1 | \
awk 'match($0, ".*/glibc-(.*).ebuild", v) { print(v[1]); }')

export LINUX_HEADERS_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-kernel/linux-headers/linux-headers-*.ebuild | tail -1 | \
awk 'match($0, ".*/linux-headers-(.*).ebuild", v) { print(v[1]); }')
</pre>

Now emerge the cross compiler.

<pre>
crossdev --binutils $BINUTILS_VER --gcc $GCC_VER --libc $GLIBC_VER \
--kernel $LINUX_HEADERS_VER --target $CROSSDEV_TARGET
</pre>

=== Install QEmu ===

A lot of packages will not cross compile properly. QEmu will help for these
packages. Install it to emulate an ARM controller.

Edit /etc/portage/make.conf.

<pre>
nano /etc/portage/make.conf
</pre>

And add the following lines.

<pre>
QEMU_SOFTMMU_TARGETS=""
QEMU_USER_TARGETS="arm"
</pre>

Also enable the use flag static-user. This builds QEmu as static binary.
QEmu will be used later in a chroot environment of an ARM controller and will
be unable to access needed shared libraries. So it must contain all these
libraries by building it in a static way.

<pre>
euse -E static-user
</pre>

All the needed libraries for QEmu must also be available as library archive
(static libs). Emerging QEmu will request to emerge these libraries as
static variants, also. Create and add these libraries in the file
"/etc/portage/package.use/qemu". Look which libraries are needed.

<pre>
emerge -pv qemu
</pre>

And add them with the use flag static-libs. Here is an Example:

<pre>
>=net-misc/curl-7.53.0 static-libs
>=sys-apps/attr-2.4.47-r2 static-libs
>=media-libs/libsdl-1.2.15-r9 static-libs

Emerge QEmu.

<pre>
emerge qemu
udevadm trigger -c add /dev/kvm
</pre>

QEmu will execute ARM binaries on the desktop computer as if it would have an
ARM controller. To achieve this, register foreign binaries and start the
systemd service.

<pre>
ln -s /usr/share/qemu/binfmt.d/qemu.conf /etc/binfmt.d/qemu.conf
systemctl start systemd-binfmt
</pre>

Now our desktop computer is able to execute ARM binaries as well as his own
binaries.

=== Install GIT ===

To get the kernel sources, GIT will be needed. Emerge it.

<pre>
emerge git
</pre>

Exit the root shell.

<pre>
exit
</pre>

Now the cross build system is ready to compile a Gentoo Linux for the Pandora.

== Install system ==

=== Prepare target file system ===

To build the system for the Pandora about 10 GB disk space is needed. Create a
directory "CrossDev" to store all data there.

<pre>
mkdir CrossDev
cd CrossDev
</pre>

In this directory two more directories will be created:

* One to store and build the Linux kernel.
* Another will store the whole system for the Pandora including QEmu which is not really a part of the system for Pandora, but it is needed as long as the building process runs.
* Some files and archives.

First get the Gentoo base system "stage3-armv7a-*.tar.bz2". Download it from
a suitable mirror of the Gentoo distribution. See
https://www.gentoo.org/downloads/mirrors for a list of mirrors.

Go to the directory "releases/arm/autobuilds". According to your target, enter

* "current-stage3-armv7a" for soft float (armv7a-softfp-linux-gnueabi),
* "current-stage3-armv7a_hardfp" for hard float (armv7a-hardfloat-linux-gnueabi).

There is a stage 3 file for ARMv7. Download this archive.

Example:

<pre>
wget http://mirror.eu.oneandone.net/linux/distributions/gentoo/gentoo/\
releases/arm/autobuilds/current-stage3-armv7a/stage3-armv7a-20161129.tar.bz2
</pre>

or

<pre>
wget http://mirror.eu.oneandone.net/linux/distributions/gentoo/gentoo/\
releases/arm/autobuilds/current-stage3-armv7a_hardfp/\
stage3-armv7a_hardfp-20161129.tar.bz2
</pre>

As long as we are cross compiling, we use "/usr/$CROSSDEV_TARGET" as working
directory. The cross compiler looks for libraries there and uses many references
to this directory. That's why "/usr/$CROSSDEV_TARGET" will be saved, so it can
be restored after the build.

<pre>
su
umask 0022
tar -cpjf ${CROSSDEV_TARGET}-saved.tar.bz2 -C /usr $CROSSDEV_TARGET
</pre>

Unpack the stage 3 archive into "/usr/$CROSSDEV_TARGET".

<pre>
tar --xattrs --numeric-owner -xpjf stage3-*.tar.bz2 -C /usr/$CROSSDEV_TARGET
</pre>

Sometimes there is a lot of garbage in the "tmp" directory. Remove it.

<pre>
rm -rf /usr/$CROSSDEV_TARGET/tmp/*
</pre>

Exit the root shell and go back to our working directory.

<pre>
exit
</pre>

=== Compile/install kernel ===

The standard Gentoo kernel will not run on the Pandora (or, at least, takes too
much effort to make it run), so download a current kernel from
https://goldelico.com using GIT.

==== Download kernel ====

Download the kernel with GIT.

<pre>
git clone git://git.goldelico.com/gta04-kernel.git
cd gta04-kernel
</pre>

==== Compile kernel ====

Prepare an environment to cross compile the kernel. First call another shell
instance for saving the current environment. This instance is not really
necessary but it is more convenient because the saved environment is restored
after exiting the new shell.

<pre>
bash
umask 0022
export ARCH=arm CROSS_COMPILE=${CROSSDEV_TARGET}-
export PS1="($ARCH) $PS1"
</pre>

The kernel does not support the blue symbols on the keys used by "Fn". To enable
this, patch the kernel using the patch file [[Cross Install Gentoo kernel-patch-Fn-keys.txt|kernel-patch-Fn-keys.txt]].

<pre>
patch -p1 <../kernel-patch-Fn-keys.txt
</pre>

This patches the files "arch/arm/boot/dts/omap3-pandora-common.dtsi" which will
get more key codes for the blue symbols and
"drivers/input/keyboard/twl4030_keypad.c" which will handle the keys.

Now a default configuration for the kernel will be created.

<pre>
make omap2plus_defconfig
</pre>

A lot of configuration must be done to make the kernel work. To ease this use
[[Cross Install Gentoo kernel-config|kernel-config]] which will configure a running
kernel for the Pandora. It uses the name "pherkad" as computer name. Change
this to any name you like in the config file. Calling oldconfig might be
necessary if "kernel-config" is too old for the current gta04-kernel.

<pre>
cp ../kernel-config .config
make oldconfig
make menuconfig
</pre>

In "General setup/Local version" change "-pherkad" to any name you like. But
use "-" as prefix.

Build the kernel and the device tree "omap3-pandora-600mhz.dtb". Pandora users
with 1 GHz units can use "omap3-pandora-1ghz.dts". Use as much CPU cores as you
have for the compiling process.

<pre>
export CPUS="$(grep processor /proc/cpuinfo | wc -l)"
make -j$CPUS zImage
make -j$CPUS modules
make omap3-pandora-600mhz.dtb
</pre>

Convert the kernel into an image for the U-Boot loader. Use any name you
like for "Linux-pherkad".

<pre>
mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008000 -n \
'Linux-pherkad' -d arch/arm/boot/zImage arch/arm/boot/uImage
</pre>

Generate a "boot.scr" file which loads the kernel image and the correct device
tree.

Keep an eye to the bootargs. It uses the following commands:

* Start the systemd as init process: "init=/lib/systemd/systemd".
* Be quiet: "quiet". This can be removed while development.
* Show a splash screen: "splash". There is currently no splash screen, so this
* Use the root file system at: "root=/dev/mmcblk0p2". Take care to use the same partition as described below.
* Use Ext 4 root file system: "rootfstype=ext4".
* Wait for root file system: "rootwait".
* Mount initially read only: "ro". systemd will remount it later as RW.
* Use the following SWAP partition for hibernation/resume: "resume=/dev/mmcblk0p3". This is currently not used.

The file "boot.txt" will be converted to the boot script "boot.src".

<pre>
cat >boot.txt <<EOF
if itest.w *0x4830a204 == 0x102f
then
setenv devicetree omap3-pandora-1ghz
else
setenv devicetree omap3-pandora-600mhz
fi
setenv defaultdisplay lcd
setenv bootargs "init=/lib/systemd/systemd quiet splash \
root=/dev/mmcblk0p2 rootfstype=ext4 rootwait ro resume=/dev/mmcblk0p3"
ext2load mmc 0:1 0x825f0000 /boot/\${devicetree}.dtb
ext2load mmc 0:1 0x80300000 /boot/uImage-pherkad
bootm 0x80300000 - 0x825f0000
EOF

mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n 'Boot script' \
-d boot.txt boot.scr
</pre>

Exit the kernel build environment.

<pre>
exit
</pre>

==== Install kernel ====

The installation of the kernel into the target directory must be done as root.
Create the "boot" directory for the kernel, device tree and boot script and
copy them to the target directory.

<pre>
su
umask 0022
cp arch/arm/boot/uImage /usr/$CROSSDEV_TARGET/boot/uImage-pherkad
cp .config /usr/$CROSSDEV_TARGET/boot/config-pherkad
cp System.map /usr/$CROSSDEV_TARGET/boot/System.map-pherkad
cp arch/arm/boot/dts/omap3-pandora-600mhz.dtb /usr/$CROSSDEV_TARGET/boot/.
cp boot.scr /usr/$CROSSDEV_TARGET/boot/.
</pre>

Create a link for the boot directory. This is used if the boot directory is an
own partition and the boot loader wants to load the kernel from "boot/uImage-*".
In our case it is not really necessary.

<pre>
(cd /usr/$CROSSDEV_TARGET/boot; ln -s . boot)
</pre>

Install all kernel modules into "target/lib/modules". The symbolic link is for
the cross compiling process to find the kernel configuration.

<pre>
make ARCH=arm CROSS_COMPILE=${CROSSDEV_TARGET}- \
INSTALL_MOD_PATH=/usr/$CROSSDEV_TARGET modules_install

(DIR="$PWD"; cd /usr/$CROSSDEV_TARGET/usr/src; ln -s $DIR linux)
cd ..
</pre>

=== Compile system ===

Now it's time to cross compile the whole Gentoo system. The base system is
already installed in the "target" directory. All the binaries there will
be compiled again with our own cross compiler. Also a lot of new packages
(more binaries) will be installed.

==== Prepare cross development system ====

Go to the target and copy all portage configurations from the desktop computer
to the target system, since we want to use the desktop computer system as
base of the Pandora system. This must be done as root.

<pre>
export FROM_DIR="$PWD"
cd /usr/$CROSSDEV_TARGET
</pre>

Edit the "make.conf" file.

<pre>
nano etc/portage/make.conf
</pre>

Change some of the lines there. You might copy some of the contents from
the desktop computer but be sure to have the same CHOST as the CROSSDEV_TARGET.
Especially add or change for the following:

<pre>
CFLAGS="-O2 -pipe -march=armv7-a -mfpu=vfpv3-d16 -mfloat-abi=softfp \
-mfpu=neon -fno-stack-protector"
</pre>

or

<pre>
CFLAGS="-O2 -pipe -march=armv7-a -mfpu=vfpv3-d16 -mfloat-abi=hard \
-mfpu=neon -fno-stack-protector"
</pre>

<pre>

GENTOO_MIRRORS="<enter your mirrors>"
PKGDIR="/usr/portage/packages/${CHOST}"
</pre>

It is recommended to activate the build of binary packages. The cross
compilation will fail to build some packages, so QEmu will build all packages
again. It is not necessary to build good cross compiled packages by QEmu again.
Using binary packages will avoid this and save a lot of time.

To avoid mixing up the binary packages of the desktop comuter and the Pandora
set PKGDIR accordingly. Example: "/usr/portage/packages/${CHOST}"

Also copy and edit some package specific files from your desktop computer.

<pre>
cp -r /etc/portage/package.* etc/portage/.
</pre>

Edit the files in "etc/portage/package.*" and configure the portage tree.

<pre>
sed -i "s/amd64/arm/g" etc/portage/package.keywords/*
rm -r etc/portage/package.keywords/cross*
rm -r etc/portage/package.mask/cross*
rm etc/portage/package.use/cross*
rm etc/portage/package.env/cross*

mkdir etc/portage/repos.conf
cp usr/share/portage/config/repos.conf etc/portage/repos.conf/gentoo.conf
rm -f etc/portage/make.profile

(cd etc/portage && \
ln -s /usr/portage/profiles/default/linux/arm/13.0/armv7a/desktop make.profile)
</pre>

Copy the world file from the desktop computer and remove all packages which
should not be installed on the Pandora system.

<pre>
cp /var/lib/portage/world var/lib/portage/world
nano var/lib/portage/world
</pre>

==== Prepare cross-compilation and QEmu environment ====

A lot of packages will fail but we will keep going the emerge process and
compile the failed packages again with QEmu.

But first update the compiler tools in the target system. They will be needed
later in the QEmu environment. If they fail here, try to do it in the QEmu
part.

Copy the static QEmu binary to the target system and set up portage for the
target system.

<pre>
cp /usr/bin/qemu-arm usr/bin/.
mkdir -p usr/portage
touch usr/portage/.keep
</pre>

Do some standard setup for the target system. Copy some personal configurations
to the root account.

<pre>
cp -L /etc/resolv.conf etc/.
cp -r etc/skel/. root/.

cp /root/.bashrc /root/.dir_colors /root/.screenrc /root/.toprc \
/root/.xsession root/.
</pre>

Some nice tools like htop are worth to install them on the Pandora.

<pre>
mkdir -m0700 root/.config
cp -r /root/.config/htop root/.config/.
</pre>

To access the root account with ssh, copy its configuration. This copies the
"id_*" files, also. Don't do this if you deliberately take care about security.

<pre>
cp -r /root/.ssh/. root/.ssh/.
</pre>

==== Start cross compilation ====

Set up a cross compilation environment (use a third shell instance).

<pre>
bash
export CBUILD=x86_64-pc-linux-gnu
export CHOST=$CROSSDEV_TARGET
export ROOT=$PWD
export PORTAGE_CONFIGROOT=$ROOT
export PS1="($CHOST) $PS1"
</pre>

Try to cross compile all packages.

<pre>
$CHOST-emerge -a binutils glibc linux-headers gcc
$CHOST-emerge -a linux-firmware
$CHOST-emerge -ae @world
</pre>

If one of them fails, save the resume list.

<pre>
$CHOST-emerge -p --resume | grep "^\[[eb].*\]" | grep -ve "^\[blocks" | \
cut -b 18- | cut -d " " -f1 | awk '{ print("=" $0); }' >tmp/packages.txt
</pre>

Now go to "Continue cross-compilation with QEmu".

==== Continue cross-compilation with QEmu ====

Enter the chroot environment and emerge the failed package again (the first one
in the packages.txt file).

The portage tree will be mounted into the target system.

In the chroot environment it might be necessary to switch the compiler. Check
if the same version of gcc is used than the cross compiler with
"gcc-config -l". Set the correct version before starting "emerge".

<pre>
mkdir -p $PWD/run/systemd/resolve
cp /run/systemd/resolve/resolv.conf $PWD/run/systemd/resolve/.
mount --rbind /proc $PWD/proc
mount --make-rslave $PWD/proc
mount --rbind /sys $PWD/sys
mount --make-rslave $PWD/sys
mount --rbind /dev $PWD/dev
mount --make-rslave $PWD/dev
mount --rbind /usr/portage $PWD/usr/portage
chroot $PWD /bin/bash
unset CBUILD CHOST ROOT PORTAGE_CONFIGROOT
env-update
source /etc/profile
cd
source ./.bashrc
export PS1="(chroot) $PS1"
emerge -aB1 $(head -1 /tmp/packages.txt)
exit
umount -l usr/portage
umount -l dev sys proc
</pre>

After fixing the failed package(s), continue with the cross compiler.

<pre>
cat tmp/packages.txt | xargs $CHOST-emerge -1
</pre>

If one of them fails again, save the resume list.

<pre>
$CHOST-emerge -p --resume | grep "^\[[eb].*\]" | grep -ve "^\[blocks" | \
cut -b 18- | cut -d " " -f1 | awk '{ print("=" $0); }' >tmp/packages.txt
</pre>

*Go back to "Continue cross-compilation with QEmu" until all packages are merged
successfully.*

Remove some leftover temporary files.

<pre>
rm -rf /var/tmp/portage/* /usr/$CROSSDEV_TARGET/var/tmp/portage/* \
/usr/$CROSSDEV_TARGET/tmp/packages.txt
</pre>

=== Fix lib64-problem ===

Some cross compiled packages install their libraries into the "lib64" directory.
This is not used on the Pandora. So we have to copy all contents from "lib64"
to "lib" and set a link for "lib64".

<pre>
rsync -avc usr/lib64/. usr/lib/.
rm -rf usr/lib64
(cd usr && ln -s lib lib64)
</pre>

=== Configure system ===

Set the key map for Pandora in the console and, as usual in Gentoo,
configure the target system.

Use to make the Pandora keyboard work on the console.
([[Cross Install Gentoo Keymap-pandora.map|keymap-pandora.map]])

And disable the suspend mode for handling the lid switch (this does
currently not work).

<pre>
cp "$FROM_DIR/keymap-pandora.map" etc/.
chmod 644 etc/keymap-pandora.map
echo >etc/vconsole.conf "KEYMAP=/etc/keymap-pandora.map"
echo >>etc/vconsole.conf "FONT=eurlatgr"
sed -i 's/#HandleLidSwitch=suspend/HandleLidSwitch=ignore/g' etc/systemd/logind.conf
</pre>

Set up the mount table. Every line in "etc/fstab" will be commented out and
new entries added. The file system labels are used to mount the partitions.

<pre>
sed -ie "s,^/,#/,g" etc/fstab

cat >>etc/fstab <<EOF
LABEL=phlnx_boot /boot ext2 noatime 1 2
LABEL=phlnx_root / ext4 errors=remount-ro,noatime 1 1
LABEL=phlnx_home /home ext4 noatime,nodev,nosuid 1 2
EOF
</pre>

Enter the chroot environment again.

<pre>
mount --rbind /proc $PWD/proc
mount --make-rslave $PWD/proc
mount --rbind /sys $PWD/sys
mount --make-rslave $PWD/sys
mount --rbind /dev $PWD/dev

chroot $PWD /bin/bash
unset CBUILD CHOST ROOT PORTAGE_CONFIGROOT
env-update
source /etc/profile
cd
source ./.bashrc
export PS1="(chroot) $PS1"
</pre>

Set a password for root.

<pre>
passwd
</pre>

Update the configuration files and read/clear all news from portage.

<pre>
dispatch-conf
eselect news list
eselect news read
eselect news purge
</pre>

Enter the time zone and generate the locale info you want (example: enable all
lines with en_US and de_DE).

<pre>
echo "Europe/Berlin" >/etc/timezone
emerge --config sys-libs/timezone-data
nano -w /etc/locale.gen
locale-gen
</pre>

Use en_US.utf8 (entry #9) as locale.

<pre>
eselect locale list
eselect locale set 9
</pre>

Set up mount table, the machine ID and host name.

<pre>
ln -sf /proc/self/mounts /etc/mtab
systemd-machine-id-setup
echo >/etc/machine-info "PRETTY_HOSTNAME=Pherkad"
echo >/etc/hostname "pherkad"
ln -snf /run/systemd/resolve/resolv.conf /etc/resolv.conf
systemctl enable systemd-resolved.service
</pre>

Exit the chroot environment.

<pre>
exit
umount -l usr/portage
umount -l dev sys proc
</pre>

Remove the QEmu binary. It is not used anymore.

<pre>
rm usr/bin/qemu-arm
</pre>

Also remove some leftovers from the cross compiler and the link to our kernel
sources.

<pre>
rm -f etc/portage/profile/package.provided
rm -f sys-include
rm -f usr/src/linux
</pre>

Copy back the target system and restore the previous cross compiler state.

<pre>
cd "$FROM_DIR"
mkdir $CROSSDEV_TARGET

rm ${CROSSDEV_TARGET}-saved.tar.bz2
</pre>

Exit the root shell.

<pre>
exit
</pre>

= Update system =

To update the system, use a similar approach as in the cross compilation phase.
Define CROSSDEV_TARGET as in "Install cross compiling system".

== Start cross-compilation ==

Set up a cross compilation environment (become root and use a second shell
instance again).

<pre>

= Create SD-card partitions phlnx_boot/root/swap/home =

Finally the target system is done. Now it's time to copy it to the Pandora.

== Pandora ==

It's recommended to partition the SD-card for the target system on the Pandora.
Otherwise the boot loader might refuse to work.

Insert the SD-card in the left slot (mmcblk0) and unmount it if necessary.

Create the following partitions:

* A boot partition (ext2).
* A root partition which will contain the target system (at least 4 GB).
* A home partition which we can use later.
* A SWAP partition which we can use later.

<pre>
sudo -s

/sbin/fdisk /dev/mmcblk0
Create new DOS partition label: o
Create new partition: n p 1 Return +8M
Create new partition: n p 2 Return +4G
Create new partition: n p 3 Return +1G
Change partition type: t 3 82 (Linux swap)
Create new partition: n p Return Return
Write all changes: w

/sbin/mkfs.ext2 -FL phlnx_boot /dev/mmcblk0p1
/sbin/mkfs.ext4 -FL phlnx_root -O ^has_journal /dev/mmcblk0p2
/sbin/mkswap -L phlnx_swap /dev/mmcblk0p3
/sbin/mkfs.ext4 -FL phlnx_home -O ^has_journal /dev/mmcblk0p4
exit
</pre>

= Option #1: Copy target system to SD-card =

One of the possibilities to copy the target system to the SD-card on the Pandora
is to use a USB cable connecting the Pandora to the desktop computer.

It's also possible to copy it via the WiFi network (see below).

== Pandora ==

Connect the Pandora via USB to the desktop computer. Insert the SD-card in the
left slot (mmcblk0). Use menu "System/SD-Mass Storage" to access partition
"phlnx_root".

== Desktop computer ==

Mount the root partition and copy the target system. Use the correct "/dev/sd*".

<pre>
su
mkdir /tmp/mnt
mount /dev/sdc /tmp/mnt
mkdir -p /tmp/mnt/boot
touch /tmp/mnt/boot/.keep
mkdir -p /tmp/mnt/home
touch /tmp/mnt/home/.keep

rsync -av --delete --exclude lost+found --exclude /boot \
CrossDev/$CROSSDEV_TARGET/. /tmp/mnt/.

umount /tmp/mnt
</pre>

== Pandora ==

Use "System/SD-Mass Storage" again to access phlnx_boot.

== Desktop computer ==

Mount the boot partition and copy boot directory of the target system.

<pre>
mount /dev/sdc /tmp/mnt
rm -f /tmp/mnt/uImage-pherkad

rsync -av --delete --exclude lost+found \
CrossDev/$CROSSDEV_TARGET/boot/. /tmp/mnt/.

umount /tmp/mnt
rmdir /tmp/mnt
exit
</pre>

== Pandora ==

End SD-Mass Storage.

= Option #2: Copy target system to SD-card via WiFi network =

== Pandora ==

Copy all files from the desktop computer to the SD-card partitions. Use the
same CROSSDEV_TARGET and FROM_DIR environment settings as on the desktop
computer.

<pre>
sudo -s
export REMOTE=mizar.spdns.de
export FROM_DIR=/home/jgeiss/Data/Systems/Pandora/Pherkad/Linux/Gentoo/CrossDev
export CROSSDEV_TARGET=armv7a-hardfloat-linux-gnueabi

mkdir -p /media/phlnx_root/boot
touch /media/phlnx_root/boot/.keep

rsync -av --numeric-ids --delete --exclude lost+found --exclude /boot \
$REMOTE:$FROM_DIR/$CROSSDEV_TARGET/. /media/phlnx_root/.

rsync -av --delete --exclude lost+found \
$REMOTE:$FROM_DIR/$CROSSDEV_TARGET/boot/. /media/phlnx_boot/.

exit
</pre>

= Boot the new system =

Reboot the Pandora and hold the right shoulder button until the boot menu
appears.

'''Sometimes it is necessary to switch off the Pandora for 10-60 seconds.'''

Choose "boot from SD1:1".

It the boot works well, login as root and play around.

== Optional: USB-networking ==

To use networking to the desktop computer via USB cable, execute the
following commands on both systems.

=== Pandora ===

<pre>
modprobe g_ether
ifconfig usb0 192.168.129.3 netmask 255.255.255.0
route add default gw 192.168.129.2
systemctl start sshd
</pre>

=== Desktop computer ===

Configure the corresponding network interface.

<pre>
ifconfig enp0s20u1u1 192.168.129.2 netmask 255.255.255.0
</pre>

Now you should be able to connect to the Pandora.

<pre>
ssh root@192.168.129.3
</pre>

== Shutdown Pandora ==

To shutdown the Pandora system enter the following command.

<pre>
systemctl poweroff
</pre>

= Open issues =

The following things are currently not working and need to be implemented/fixed:

* WiFi interface is missing
* twl: not initialized
* omapfb omapfb: no displays, failed to setup omapfb
* omap2_set_init_voltage: unable to find boot up OPP vor ...
* __nand_correct_data: uncorrectable ECC error

Cross Install Gentoo

Jgeiss: /* Open issues */

= Cross install Gentoo Linux on Pandora =

== Introduction ==

These instructions are for installing a recent Gentoo Linux on the OpenPandora
handheld console. The system will be installed and booted from a SD-card. The
Gentoo Linux will be cross-compiled on another desktop computer also running
Gentoo Linux.

It is not necessary to follow all instructions exactly. Some of them can be
changed to your own needs.

'''The system currently supports only the text console and no X11 or sound.'''
'''Also a lot of features are missing.''' See "Open issues" at the end.

=== Prerequisites ===

These instructions assume the following prerequisites:

* Good knowledge in Gentoo Linux.
* A desktop computer running Gentoo Linux. Other Linux is, of course, also possible but requires proper adaption of these instructions.
* An OpenPandora handheld console.
* A SD-card with least 8 GB size.
* A USB cable to connect the Pandora to the desktop computer.

=== Improvement ===

Due to the constant changes of the Linux kernel, GNU software, etc. this
document will be outdated very quick. To avoid this, help is always appreciated
improving this document. If you can update, improve, add or complete this
document, don't hesitate to do so.

== Prepare/install cross compile system ==

To perform the cross-compilation a cross compiler and QEmu must be installed
on the desktop computer. QEmu will help a lot for compiling packages which
will not properly cross compile.

=== Install cross compiling system ===

For compiling software for an ARM controller a cross compiler must be installed.

We can use ARMv7 using either soft float (armv7a-softfp-linux-gnueabi) or hard
float (armv7a-hardfloat-linux-gnueabi).

<pre>export CROSSDEV_TARGET=armv7a-softfp-linux-gnueabi</pre>

or

<pre>export CROSSDEV_TARGET=armv7a-hardfloat-linux-gnueabi</pre>

The additional portage tree in "/usr/local/portage-crossdev" will hold all
information for emerging the cross build system (cross compiler and tools).

To prepare emerging a cross compiler, execute the following commands.

<pre>
su
umask 0022

emerge -av crossdev

mkdir -p /usr/local/portage-crossdev/{profiles,metadata}

echo 'local-crossdev' >/usr/local/portage-crossdev/profiles/repo_name
echo 'masters = gentoo' >/usr/local/portage-crossdev/metadata/layout.conf
echo 'thin-manifests = true' >>/usr/local/portage-crossdev/metadata/layout.conf
chown -R portage:portage /usr/local/portage-crossdev

echo '[local-crossdev]' >/etc/portage/repos.conf/crossdev.conf

echo 'location = /usr/local/portage-crossdev' \
>>/etc/portage/repos.conf/crossdev.conf

echo 'priority = 10' >>/etc/portage/repos.conf/crossdev.conf
echo 'masters = gentoo' >>/etc/portage/repos.conf/crossdev.conf
echo 'auto-sync = no' >>/etc/portage/repos.conf/crossdev.conf
</pre>

The portage tree for emerging the cross build system is set up. Now we have to
find out which versions of the cross build components are about to be installed.
The target system will get binutils, gcc, glibc and linux-headers of a certain
version. The same version should be installed in the cross build system.

<pre>
export BINUTILS_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-devel/binutils/binutils-*.ebuild | tail -1 | \
awk 'match($0, ".*/binutils-(.*).ebuild", v) { print(v[1]); }')

export GCC_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-devel/gcc/gcc-*.ebuild | tail -1 | \
awk 'match($0, ".*/gcc-(.*).ebuild", v) { print(v[1]); }')

export GLIBC_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-libs/glibc/glibc-*.ebuild | tail -1 | \
awk 'match($0, ".*/glibc-(.*).ebuild", v) { print(v[1]); }')

export LINUX_HEADERS_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-kernel/linux-headers/linux-headers-*.ebuild | tail -1 | \
awk 'match($0, ".*/linux-headers-(.*).ebuild", v) { print(v[1]); }')
</pre>

Now emerge the cross compiler.

<pre>
crossdev --binutils $BINUTILS_VER --gcc $GCC_VER --libc $GLIBC_VER \
--kernel $LINUX_HEADERS_VER --target $CROSSDEV_TARGET
</pre>

=== Install QEmu ===

A lot of packages will not cross compile properly. QEmu will help for these
packages. Install it to emulate an ARM controller.

Edit /etc/portage/make.conf.

<pre>
nano /etc/portage/make.conf
</pre>

And add the following lines.

<pre>
QEMU_SOFTMMU_TARGETS=""
QEMU_USER_TARGETS="arm"
</pre>

Also enable the use flag static-user. This builds QEmu as static binary.
QEmu will be used later in a chroot environment of an ARM controller and will
be unable to access needed shared libraries. So it must contain all these
libraries by building it in a static way.

<pre>
euse -E static-user
</pre>

All the needed libraries for QEmu must also be available as library archive
(static libs). Emerging QEmu will request to emerge these libraries as
static variants, also. Create and add these libraries in the file
"/etc/portage/package.use/qemu". Look which libraries are needed.

<pre>
emerge -pv qemu
</pre>

And add them with the use flag static-libs. Here is an Example:

<pre>
>=net-misc/curl-7.53.0 static-libs
>=sys-apps/attr-2.4.47-r2 static-libs
>=media-libs/libsdl-1.2.15-r9 static-libs
>=sys-apps/dtc-1.4.1 static-libs
>=app-arch/bzip2-1.0.6-r7 static-libs
>=x11-libs/pixman-0.34.0 static-libs
>=dev-libs/libpcre-8.40-r1 static-libs
>=sys-libs/libseccomp-2.3.0 static-libs
>=net-fs/libnfs-1.9.7 static-libs
>=dev-libs/cyrus-sasl-2.1.26-r9 static-libs
>=dev-libs/gmp-6.1.0 static-libs
>=dev-libs/libaio-0.3.110 static-libs
>=sys-fs/xfsprogs-4.5.0 static-libs
>=sys-libs/zlib-1.2.11 static-libs
>=media-libs/libjpeg-turbo-1.5.0 static-libs
>=sys-libs/libcap-ng-0.7.8 static-libs
>=dev-libs/openssl-1.0.2k static-libs
>=dev-libs/glib-2.50.3-r1 static-libs
>=virtual/jpeg-0-r2:0 static-libs
>=media-libs/libpng-1.6.27 static-libs
>=sys-libs/ncurses-6.0-r1 static-libs
</pre>

Emerge QEmu.

<pre>
emerge qemu
udevadm trigger -c add /dev/kvm
</pre>

QEmu will execute ARM binaries on the desktop computer as if it would have an
ARM controller. To achieve this, register foreign binaries and start the
systemd service.

<pre>
ln -s /usr/share/qemu/binfmt.d/qemu.conf /etc/binfmt.d/qemu.conf
systemctl start systemd-binfmt
</pre>

Now our desktop computer is able to execute ARM binaries as well as his own
binaries.

=== Install GIT ===

To get the kernel sources, GIT will be needed. Emerge it.

<pre>
emerge git
</pre>

Exit the root shell.

<pre>
exit
</pre>

Now the cross build system is ready to compile a Gentoo Linux for the Pandora.

== Install system ==

=== Prepare target file system ===

To build the system for the Pandora about 10 GB disk space is needed. Create a
directory "CrossDev" to store all data there.

<pre>
mkdir CrossDev
cd CrossDev
</pre>

In this directory two more directories will be created:

* One to store and build the Linux kernel.
* Another will store the whole system for the Pandora including QEmu which is not really a part of the system for Pandora, but it is needed as long as the building process runs.
* Some files and archives.

First get the Gentoo base system "stage3-armv7a-*.tar.bz2". Download it from
a suitable mirror of the Gentoo distribution. See
https://www.gentoo.org/downloads/mirrors for a list of mirrors.

Go to the directory "releases/arm/autobuilds". According to your target, enter

* "current-stage3-armv7a" for soft float (armv7a-softfp-linux-gnueabi),
* "current-stage3-armv7a_hardfp" for hard float (armv7a-hardfloat-linux-gnueabi).

There is a stage 3 file for ARMv7. Download this archive.

Example:

<pre>
wget http://mirror.eu.oneandone.net/linux/distributions/gentoo/gentoo/\
releases/arm/autobuilds/current-stage3-armv7a/stage3-armv7a-20161129.tar.bz2
</pre>

or

<pre>
wget http://mirror.eu.oneandone.net/linux/distributions/gentoo/gentoo/\
releases/arm/autobuilds/current-stage3-armv7a_hardfp/\
stage3-armv7a_hardfp-20161129.tar.bz2
</pre>

As long as we are cross compiling, we use "/usr/$CROSSDEV_TARGET" as working
directory. The cross compiler looks for libraries there and uses many references
to this directory. That's why "/usr/$CROSSDEV_TARGET" will be saved, so it can
be restored after the build.

<pre>
su
umask 0022
tar -cpjf ${CROSSDEV_TARGET}-saved.tar.bz2 -C /usr $CROSSDEV_TARGET
</pre>

Unpack the stage 3 archive into "/usr/$CROSSDEV_TARGET".

<pre>
tar --xattrs --numeric-owner -xpjf stage3-*.tar.bz2 -C /usr/$CROSSDEV_TARGET
</pre>

Sometimes there is a lot of garbage in the "tmp" directory. Remove it.

<pre>
rm -rf /usr/$CROSSDEV_TARGET/tmp/*
</pre>

Exit the root shell and go back to our working directory.

<pre>
exit
</pre>

=== Compile/install kernel ===

The standard Gentoo kernel will not run on the Pandora (or, at least, takes too
much effort to make it run), so download a current kernel from
https://goldelico.com using GIT.

==== Download kernel ====

Download the kernel with GIT.

<pre>
git clone git://git.goldelico.com/gta04-kernel.git
cd gta04-kernel
</pre>

==== Compile kernel ====

Prepare an environment to cross compile the kernel. First call another shell
instance for saving the current environment. This instance is not really
necessary but it is more convenient because the saved environment is restored
after exiting the new shell.

<pre>
bash
umask 0022
export ARCH=arm CROSS_COMPILE=${CROSSDEV_TARGET}-
export PS1="($ARCH) $PS1"
</pre>

The kernel does not support the blue symbols on the keys used by "Fn". To enable
this, patch the kernel using the patch file [[Cross Install Gentoo kernel-patch-Fn-keys.txt|kernel-patch-Fn-keys.txt]].

<pre>
patch -p1 <../kernel-patch-Fn-keys.txt
</pre>

This patches the files "arch/arm/boot/dts/omap3-pandora-common.dtsi" which will
get more key codes for the blue symbols and
"drivers/input/keyboard/twl4030_keypad.c" which will handle the keys.

Now a default configuration for the kernel will be created.

<pre>
make omap2plus_defconfig
</pre>

A lot of configuration must be done to make the kernel work. To ease this use
[[Cross Install Gentoo kernel-config|kernel-config]] which will configure a running
kernel for the Pandora. It uses the name "pherkad" as computer name. Change
this to any name you like in the config file. Calling oldconfig might be
necessary if "kernel-config" is too old for the current gta04-kernel.

<pre>
cp ../kernel-config .config
make oldconfig
make menuconfig
</pre>

In "General setup/Local version" change "-pherkad" to any name you like. But
use "-" as prefix.

Build the kernel and the device tree "omap3-pandora-600mhz.dtb". Pandora users
with 1 GHz units can use "omap3-pandora-1ghz.dts". Use as much CPU cores as you
have for the compiling process.

<pre>
export CPUS="$(grep processor /proc/cpuinfo | wc -l)"
make -j$CPUS zImage
make -j$CPUS modules
make omap3-pandora-600mhz.dtb
</pre>

Convert the kernel into an image for the U-Boot loader. Use any name you
like for "Linux-pherkad".

<pre>
mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008000 -n \
'Linux-pherkad' -d arch/arm/boot/zImage arch/arm/boot/uImage
</pre>

Generate a "boot.scr" file which loads the kernel image and the correct device
tree.

Keep an eye to the bootargs. It uses the following commands:

* Start the systemd as init process: "init=/lib/systemd/systemd".
* Be quiet: "quiet". This can be removed while development.
* Show a splash screen: "splash". There is currently no splash screen, so this
* Use the root file system at: "root=/dev/mmcblk0p2". Take care to use the same partition as described below.
* Use Ext 4 root file system: "rootfstype=ext4".
* Wait for root file system: "rootwait".
* Mount initially read only: "ro". systemd will remount it later as RW.
* Use the following SWAP partition for hibernation/resume: "resume=/dev/mmcblk0p3". This is currently not used.

The file "boot.txt" will be converted to the boot script "boot.src".

<pre>
cat >boot.txt <<EOF
if itest.w *0x4830a204 == 0x102f
then
setenv devicetree omap3-pandora-1ghz
else
setenv devicetree omap3-pandora-600mhz
fi
setenv defaultdisplay lcd
setenv bootargs "init=/lib/systemd/systemd quiet splash \
root=/dev/mmcblk0p2 rootfstype=ext4 rootwait ro resume=/dev/mmcblk0p3"
ext2load mmc 0:1 0x825f0000 /boot/\${devicetree}.dtb
ext2load mmc 0:1 0x80300000 /boot/uImage-pherkad
bootm 0x80300000 - 0x825f0000
EOF

mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n 'Boot script' \
-d boot.txt boot.scr
</pre>

Exit the kernel build environment.

<pre>
exit
</pre>

==== Install kernel ====

The installation of the kernel into the target directory must be done as root.
Create the "boot" directory for the kernel, device tree and boot script and
copy them to the target directory.

<pre>
su
umask 0022
cp arch/arm/boot/uImage /usr/$CROSSDEV_TARGET/boot/uImage-pherkad
cp .config /usr/$CROSSDEV_TARGET/boot/config-pherkad
cp System.map /usr/$CROSSDEV_TARGET/boot/System.map-pherkad
cp arch/arm/boot/dts/omap3-pandora-600mhz.dtb /usr/$CROSSDEV_TARGET/boot/.
cp boot.scr /usr/$CROSSDEV_TARGET/boot/.
</pre>

Create a link for the boot directory. This is used if the boot directory is an
own partition and the boot loader wants to load the kernel from "boot/uImage-*".
In our case it is not really necessary.

<pre>
(cd /usr/$CROSSDEV_TARGET/boot; ln -s . boot)
</pre>

Install all kernel modules into "target/lib/modules". The symbolic link is for
the cross compiling process to find the kernel configuration.

<pre>
make ARCH=arm CROSS_COMPILE=${CROSSDEV_TARGET}- \
INSTALL_MOD_PATH=/usr/$CROSSDEV_TARGET modules_install

(DIR="$PWD"; cd /usr/$CROSSDEV_TARGET/usr/src; ln -s $DIR linux)
cd ..
</pre>

=== Compile system ===

Now it's time to cross compile the whole Gentoo system. The base system is
already installed in the "target" directory. All the binaries there will
be compiled again with our own cross compiler. Also a lot of new packages
(more binaries) will be installed.

==== Prepare cross development system ====

Go to the target and copy all portage configurations from the desktop computer
to the target system, since we want to use the desktop computer system as
base of the Pandora system. This must be done as root.

<pre>
export FROM_DIR="$PWD"
cd /usr/$CROSSDEV_TARGET
</pre>

Edit the "make.conf" file.

<pre>
nano etc/portage/make.conf
</pre>

Change some of the lines there. You might copy some of the contents from
the desktop computer but be sure to have the same CHOST as the CROSSDEV_TARGET.
Especially add or change for the following:

<pre>
CFLAGS="-O2 -pipe -march=armv7-a -mfpu=vfpv3-d16 -mfloat-abi=softfp \
-mfpu=neon -fno-stack-protector"
</pre>

or

<pre>
CFLAGS="-O2 -pipe -march=armv7-a -mfpu=vfpv3-d16 -mfloat-abi=hard \
-mfpu=neon -fno-stack-protector"
</pre>

<pre>

--binpkg-respect-use=y"

GENTOO_MIRRORS="<enter your mirrors>"
PKGDIR="/usr/portage/packages/${CHOST}"
</pre>

It is recommended to activate the build of binary packages. The cross
compilation will fail to build some packages, so QEmu will build all packages
again. It is not necessary to build good cross compiled packages by QEmu again.
Using binary packages will avoid this and save a lot of time.

To avoid mixing up the binary packages of the desktop comuter and the Pandora
set PKGDIR accordingly. Example: "/usr/portage/packages/${CHOST}"

Also copy and edit some package specific files from your desktop computer.

<pre>
cp -r /etc/portage/package.* etc/portage/.
</pre>

Edit the files in "etc/portage/package.*" and configure the portage tree.

<pre>
sed -i "s/amd64/arm/g" etc/portage/package.keywords/*
rm -r etc/portage/package.keywords/cross*
rm -r etc/portage/package.mask/cross*
rm etc/portage/package.use/cross*
rm etc/portage/package.env/cross*

mkdir etc/portage/repos.conf
cp usr/share/portage/config/repos.conf etc/portage/repos.conf/gentoo.conf
rm -f etc/portage/make.profile

(cd etc/portage && \
ln -s /usr/portage/profiles/default/linux/arm/13.0/armv7a/desktop make.profile)
</pre>

Copy the world file from the desktop computer and remove all packages which
should not be installed on the Pandora system.

<pre>
cp /var/lib/portage/world var/lib/portage/world
nano var/lib/portage/world
</pre>

==== Prepare cross-compilation and QEmu environment ====

A lot of packages will fail but we will keep going the emerge process and
compile the failed packages again with QEmu.

But first update the compiler tools in the target system. They will be needed
later in the QEmu environment. If they fail here, try to do it in the QEmu
part.

Copy the static QEmu binary to the target system and set up portage for the
target system.

<pre>
cp /usr/bin/qemu-arm usr/bin/.
mkdir -p usr/portage
touch usr/portage/.keep
</pre>

Do some standard setup for the target system. Copy some personal configurations
to the root account.

<pre>
cp -L /etc/resolv.conf etc/.
cp -r etc/skel/. root/.

cp /root/.bashrc /root/.dir_colors /root/.screenrc /root/.toprc \
/root/.xsession root/.
</pre>

Some nice tools like htop are worth to install them on the Pandora.

<pre>
mkdir -m0700 root/.config
cp -r /root/.config/htop root/.config/.
</pre>

To access the root account with ssh, copy its configuration. This copies the
"id_*" files, also. Don't do this if you deliberately take care about security.

<pre>
cp -r /root/.ssh/. root/.ssh/.
</pre>

==== Start cross compilation ====

Set up a cross compilation environment (use a third shell instance).

<pre>
bash
export CBUILD=x86_64-pc-linux-gnu
export CHOST=$CROSSDEV_TARGET

Try to cross compile all packages.

<pre>
$CHOST-emerge -a binutils glibc linux-headers gcc
$CHOST-emerge -a linux-firmware
$CHOST-emerge -ae @world
</pre>

If one of them fails, save the resume list.

<pre>
$CHOST-emerge -p --resume | grep "^\[[eb].*\]" | grep -ve "^\[blocks" | \
cut -b 18- | cut -d " " -f1 | awk '{ print("=" $0); }' >tmp/packages.txt
</pre>

Now go to "Continue cross-compilation with QEmu".

==== Continue cross-compilation with QEmu ====

Enter the chroot environment and emerge the failed package again (the first one
in the packages.txt file).

The portage tree will be mounted into the target system.

In the chroot environment it might be necessary to switch the compiler. Check
if the same version of gcc is used than the cross compiler with
"gcc-config -l". Set the correct version before starting "emerge".

<pre>

After fixing the failed package(s), continue with the cross compiler.

<pre>
cat tmp/packages.txt | xargs $CHOST-emerge -1
</pre>

If one of them fails again, save the resume list.

<pre>
$CHOST-emerge -p --resume | grep "^\[[eb].*\]" | grep -ve "^\[blocks" | \
cut -b 18- | cut -d " " -f1 | awk '{ print("=" $0); }' >tmp/packages.txt
</pre>

*Go back to "Continue cross-compilation with QEmu" until all packages are merged
successfully.*

Remove some leftover temporary files.

<pre>
rm -rf /var/tmp/portage/* /usr/$CROSSDEV_TARGET/var/tmp/portage/* \
/usr/$CROSSDEV_TARGET/tmp/packages.txt
</pre>

=== Fix lib64-problem ===

Some cross compiled packages install their libraries into the "lib64" directory.
This is not used on the Pandora. So we have to copy all contents from "lib64"
to "lib" and set a link for "lib64".

<pre>
rsync -avc usr/lib64/. usr/lib/.
rm -rf usr/lib64
(cd usr && ln -s lib lib64)
</pre>

=== Configure system ===

Set the key map for Pandora in the console and, as usual in Gentoo,
configure the target system.

Use to make the Pandora keyboard work on the console.
([[Cross Install Gentoo Keymap-pandora.map|keymap-pandora.map]])

And disable the suspend mode for handling the lid switch (this does
currently not work).

<pre>
cp "$FROM_DIR/keymap-pandora.map" etc/.
chmod 644 etc/keymap-pandora.map
echo >etc/vconsole.conf "KEYMAP=/etc/keymap-pandora.map"
echo >>etc/vconsole.conf "FONT=eurlatgr"
sed -i 's/#HandleLidSwitch=suspend/HandleLidSwitch=ignore/g' etc/systemd/logind.conf
</pre>

Set up the mount table. Every line in "etc/fstab" will be commented out and
new entries added. The file system labels are used to mount the partitions.

<pre>
sed -ie "s,^/,#/,g" etc/fstab

cat >>etc/fstab <<EOF
LABEL=phlnx_boot /boot ext2 noatime 1 2
LABEL=phlnx_root / ext4 errors=remount-ro,noatime 1 1
LABEL=phlnx_home /home ext4 noatime,nodev,nosuid 1 2
EOF
</pre>

Enter the chroot environment again.

Update the configuration files and read/clear all news from portage.

<pre>
dispatch-conf
eselect news list
eselect news read

</pre>

Enter the time zone and generate the locale info you want (example: enable all
lines with en_US and de_DE).

<pre>
echo "Europe/Berlin" >/etc/timezone
emerge --config sys-libs/timezone-data
nano -w /etc/locale.gen
locale-gen
</pre>

Use en_US.utf8 (entry #9) as locale.

<pre>
eselect locale list
eselect locale set 9
</pre>

Set up mount table, the machine ID and host name.

<pre>
ln -sf /proc/self/mounts /etc/mtab
systemd-machine-id-setup
echo >/etc/machine-info "PRETTY_HOSTNAME=Pherkad"
echo >/etc/hostname "pherkad"
ln -snf /run/systemd/resolve/resolv.conf /etc/resolv.conf
systemctl enable systemd-resolved.service
</pre>

Exit the chroot environment.

<pre>
exit
umount -l usr/portage
umount -l dev sys proc
</pre>

Remove the QEmu binary. It is not used anymore.

<pre>
rm usr/bin/qemu-arm
</pre>

Also remove some leftovers from the cross compiler and the link to our kernel
sources.

<pre>
rm -f etc/portage/profile/package.provided

= Create SD-card partitions phlnx_boot/root/swap/home =

Finally the target system is done. Now it's time to copy it to the Pandora.

== Pandora ==

It's recommended to partition the SD-card for the target system on the Pandora.
Otherwise the boot loader might refuse to work.

Insert the SD-card in the left slot (mmcblk0) and unmount it if necessary.

Create the following partitions:

* A boot partition (ext2).
* A root partition which will contain the target system (at least 4 GB).
* A home partition which we can use later.
* A SWAP partition which we can use later.

<pre>
sudo -s

/sbin/fdisk /dev/mmcblk0
Create new DOS partition label: o
Create new partition: n p 1 Return +8M
Create new partition: n p 2 Return +4G
Create new partition: n p 3 Return +1G
Change partition type: t 3 82 (Linux swap)
Create new partition: n p Return Return
Write all changes: w

/sbin/mkfs.ext2 -FL phlnx_boot /dev/mmcblk0p1
/sbin/mkfs.ext4 -FL phlnx_root -O ^has_journal /dev/mmcblk0p2
/sbin/mkswap -L phlnx_swap /dev/mmcblk0p3
/sbin/mkfs.ext4 -FL phlnx_home -O ^has_journal /dev/mmcblk0p4
exit
</pre>

= Option #1: Copy target system to SD-card =

One of the possibilities to copy the target system to the SD-card on the Pandora
is to use a USB cable connecting the Pandora to the desktop computer.

It's also possible to copy it via the WiFi network (see below).

== Pandora ==

Connect the Pandora via USB to the desktop computer. Insert the SD-card in the
left slot (mmcblk0). Use menu "System/SD-Mass Storage" to access partition
"phlnx_root".

== Desktop computer ==

Mount the root partition and copy the target system. Use the correct "/dev/sd*".

<pre>
su
mkdir /tmp/mnt
mount /dev/sdc /tmp/mnt
mkdir -p /tmp/mnt/boot
touch /tmp/mnt/boot/.keep
mkdir -p /tmp/mnt/home
touch /tmp/mnt/home/.keep

rsync -av --delete --exclude lost+found --exclude /boot \
CrossDev/$CROSSDEV_TARGET/. /tmp/mnt/.

umount /tmp/mnt
</pre>

== Pandora ==

Use "System/SD-Mass Storage" again to access phlnx_boot.

== Desktop computer ==

Mount the boot partition and copy boot directory of the target system.

<pre>
mount /dev/sdc /tmp/mnt
rm -f /tmp/mnt/uImage-pherkad

rsync -av --delete --exclude lost+found \
CrossDev/$CROSSDEV_TARGET/boot/. /tmp/mnt/.

umount /tmp/mnt
rmdir /tmp/mnt
exit
</pre>

== Pandora ==

End SD-Mass Storage.

= Option #2: Copy target system to SD-card via WiFi network =

== Pandora ==

Copy all files from the desktop computer to the SD-card partitions. Use the
same CROSSDEV_TARGET and FROM_DIR environment settings as on the desktop
computer.

<pre>
sudo -s
export REMOTE=mizar.spdns.de
export FROM_DIR=/home/jgeiss/Data/Systems/Pandora/Pherkad/Linux/Gentoo/CrossDev
export CROSSDEV_TARGET=armv7a-hardfloat-linux-gnueabi

mkdir -p /media/phlnx_root/boot
touch /media/phlnx_root/boot/.keep

rsync -av --numeric-ids --delete --exclude lost+found --exclude /boot \
$REMOTE:$FROM_DIR/$CROSSDEV_TARGET/. /media/phlnx_root/.

rsync -av --delete --exclude lost+found \
$REMOTE:$FROM_DIR/$CROSSDEV_TARGET/boot/. /media/phlnx_boot/.

exit
</pre>

= Boot the new system =

Reboot the Pandora and hold the right shoulder button until the boot menu
appears.

'''Sometimes it is necessary to switch off the Pandora for 10-60 seconds.'''

Choose "boot from SD1:1".

It the boot works well, login as root and play around.

== Optional: USB-networking ==

To use networking to the desktop computer via USB cable, execute the
following commands on both systems.

=== Pandora ===

<pre>
modprobe g_ether
ifconfig usb0 192.168.129.3 netmask 255.255.255.0
route add default gw 192.168.129.2
systemctl start sshd
</pre>

=== Desktop computer ===

Configure the corresponding network interface.

<pre>
ifconfig enp0s20u1u1 192.168.129.2 netmask 255.255.255.0
</pre>

Now you should be able to connect to the Pandora.

<pre>
ssh root@192.168.129.3
</pre>

== Shutdown Pandora ==

To shutdown the Pandora system enter the following command.

<pre>
systemctl poweroff
</pre>

= Open issues =

The following things are currently not working and need to be implemented/fixed:

* WiFi interface is missing
* tw1: not initialized
* omapfb omapfb: no displays, failed to setup omapfb
* omap2_set_init_voltage: unable to find boot up OPP vor ...
* __nand_correct_data: uncorrectable ECC error
* Buffer I/O error on dev mtdblock0, logical block 0, async page read
* Cursor and other GPIO-related keys do not work correctly if CPU is idle. Workaround: echo 1 >/sys/devices/system/cpu/cpu0/cpuidle/state4/disable
* Kernel panic at system shutdown

Cross Install Gentoo

2018-06-10T13:17:31Z

Jgeiss: /* Configure system */

= Cross install Gentoo Linux on Pandora =

== Introduction ==

These instructions are for installing a recent Gentoo Linux on the OpenPandora
handheld console. The system will be installed and booted from a SD-card. The
Gentoo Linux will be cross-compiled on another desktop computer also running
Gentoo Linux.

It is not necessary to follow all instructions exactly. Some of them can be
changed to your own needs.

'''The system currently supports only the text console and no X11 or sound.'''
'''Also a lot of features are missing.''' See "Open issues" at the end.

=== Prerequisites ===

These instructions assume the following prerequisites:

* Good knowledge in Gentoo Linux.
* A desktop computer running Gentoo Linux. Other Linux is, of course, also possible but requires proper adaption of these instructions.
* An OpenPandora handheld console.
* A SD-card with least 8 GB size.
* A USB cable to connect the Pandora to the desktop computer.

=== Improvement ===

Due to the constant changes of the Linux kernel, GNU software, etc. this
document will be outdated very quick. To avoid this, help is always appreciated
improving this document. If you can update, improve, add or complete this
document, don't hesitate to do so.

== Prepare/install cross compile system ==

To perform the cross-compilation a cross compiler and QEmu must be installed
on the desktop computer. QEmu will help a lot for compiling packages which
will not properly cross compile.

=== Install cross compiling system ===

For compiling software for an ARM controller a cross compiler must be installed.

We can use ARMv7 using either soft float (armv7a-softfp-linux-gnueabi) or hard
float (armv7a-hardfloat-linux-gnueabi).

<pre>export CROSSDEV_TARGET=armv7a-softfp-linux-gnueabi</pre>

or

<pre>export CROSSDEV_TARGET=armv7a-hardfloat-linux-gnueabi</pre>

The additional portage tree in "/usr/local/portage-crossdev" will hold all
information for emerging the cross build system (cross compiler and tools).

To prepare emerging a cross compiler, execute the following commands.

<pre>
su
umask 0022

emerge -av crossdev

mkdir -p /usr/local/portage-crossdev/{profiles,metadata}

echo 'local-crossdev' >/usr/local/portage-crossdev/profiles/repo_name
echo 'masters = gentoo' >/usr/local/portage-crossdev/metadata/layout.conf
echo 'thin-manifests = true' >>/usr/local/portage-crossdev/metadata/layout.conf
chown -R portage:portage /usr/local/portage-crossdev

echo '[local-crossdev]' >/etc/portage/repos.conf/crossdev.conf

echo 'location = /usr/local/portage-crossdev' \
>>/etc/portage/repos.conf/crossdev.conf

echo 'priority = 10' >>/etc/portage/repos.conf/crossdev.conf
echo 'masters = gentoo' >>/etc/portage/repos.conf/crossdev.conf
echo 'auto-sync = no' >>/etc/portage/repos.conf/crossdev.conf
</pre>

The portage tree for emerging the cross build system is set up. Now we have to
find out which versions of the cross build components are about to be installed.
The target system will get binutils, gcc, glibc and linux-headers of a certain
version. The same version should be installed in the cross build system.

<pre>
export BINUTILS_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-devel/binutils/binutils-*.ebuild | tail -1 | \
awk 'match($0, ".*/binutils-(.*).ebuild", v) { print(v[1]); }')

export GCC_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-devel/gcc/gcc-*.ebuild | tail -1 | \
awk 'match($0, ".*/gcc-(.*).ebuild", v) { print(v[1]); }')

export GLIBC_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-libs/glibc/glibc-*.ebuild | tail -1 | \
awk 'match($0, ".*/glibc-(.*).ebuild", v) { print(v[1]); }')

export LINUX_HEADERS_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-kernel/linux-headers/linux-headers-*.ebuild | tail -1 | \
awk 'match($0, ".*/linux-headers-(.*).ebuild", v) { print(v[1]); }')
</pre>

Now emerge the cross compiler.

<pre>
crossdev --binutils $BINUTILS_VER --gcc $GCC_VER --libc $GLIBC_VER \
--kernel $LINUX_HEADERS_VER --target $CROSSDEV_TARGET
</pre>

=== Install QEmu ===

A lot of packages will not cross compile properly. QEmu will help for these
packages. Install it to emulate an ARM controller.

Edit /etc/portage/make.conf.

<pre>
nano /etc/portage/make.conf
</pre>

And add the following lines.

<pre>
QEMU_SOFTMMU_TARGETS=""
QEMU_USER_TARGETS="arm"
</pre>

Also enable the use flag static-user. This builds QEmu as static binary.
QEmu will be used later in a chroot environment of an ARM controller and will
be unable to access needed shared libraries. So it must contain all these
libraries by building it in a static way.

<pre>
euse -E static-user
</pre>

All the needed libraries for QEmu must also be available as library archive
(static libs). Emerging QEmu will request to emerge these libraries as
static variants, also. Create and add these libraries in the file
"/etc/portage/package.use/qemu". Look which libraries are needed.

<pre>
emerge -pv qemu
</pre>

And add them with the use flag static-libs. Here is an Example:

<pre>
>=net-misc/curl-7.53.0 static-libs
>=sys-apps/attr-2.4.47-r2 static-libs
>=media-libs/libsdl-1.2.15-r9 static-libs
>=sys-apps/dtc-1.4.1 static-libs
>=app-arch/bzip2-1.0.6-r7 static-libs
>=x11-libs/pixman-0.34.0 static-libs
>=dev-libs/libpcre-8.40-r1 static-libs
>=sys-libs/libseccomp-2.3.0 static-libs
>=net-fs/libnfs-1.9.7 static-libs
>=dev-libs/cyrus-sasl-2.1.26-r9 static-libs
>=dev-libs/gmp-6.1.0 static-libs
>=dev-libs/libaio-0.3.110 static-libs
>=sys-fs/xfsprogs-4.5.0 static-libs
>=sys-libs/zlib-1.2.11 static-libs
>=media-libs/libjpeg-turbo-1.5.0 static-libs
>=sys-libs/libcap-ng-0.7.8 static-libs
>=dev-libs/openssl-1.0.2k static-libs
>=dev-libs/glib-2.50.3-r1 static-libs
>=virtual/jpeg-0-r2:0 static-libs
>=media-libs/libpng-1.6.27 static-libs
>=sys-libs/ncurses-6.0-r1 static-libs
</pre>

Emerge QEmu.

<pre>
emerge qemu
udevadm trigger -c add /dev/kvm
</pre>

QEmu will execute ARM binaries on the desktop computer as if it would have an
ARM controller. To achieve this, register foreign binaries and start the
systemd service.

<pre>
ln -s /usr/share/qemu/binfmt.d/qemu.conf /etc/binfmt.d/qemu.conf
systemctl start systemd-binfmt
</pre>

Now our desktop computer is able to execute ARM binaries as well as his own
binaries.

=== Install GIT ===

To get the kernel sources, GIT will be needed. Emerge it.

<pre>
emerge git
</pre>

Exit the root shell.

<pre>
exit
</pre>

Now the cross build system is ready to compile a Gentoo Linux for the Pandora.

== Install system ==

=== Prepare target file system ===

To build the system for the Pandora about 10 GB disk space is needed. Create a
directory "CrossDev" to store all data there.

<pre>
mkdir CrossDev
cd CrossDev
</pre>

In this directory two more directories will be created:

* One to store and build the Linux kernel.
* Another will store the whole system for the Pandora including QEmu which is not really a part of the system for Pandora, but it is needed as long as the building process runs.
* Some files and archives.

First get the Gentoo base system "stage3-armv7a-*.tar.bz2". Download it from
a suitable mirror of the Gentoo distribution. See
https://www.gentoo.org/downloads/mirrors for a list of mirrors.

Go to the directory "releases/arm/autobuilds". According to your target, enter

* "current-stage3-armv7a" for soft float (armv7a-softfp-linux-gnueabi),
* "current-stage3-armv7a_hardfp" for hard float (armv7a-hardfloat-linux-gnueabi).

There is a stage 3 file for ARMv7. Download this archive.

Example:

<pre>
wget http://mirror.eu.oneandone.net/linux/distributions/gentoo/gentoo/\
releases/arm/autobuilds/current-stage3-armv7a/stage3-armv7a-20161129.tar.bz2
</pre>

or

<pre>
wget http://mirror.eu.oneandone.net/linux/distributions/gentoo/gentoo/\
releases/arm/autobuilds/current-stage3-armv7a_hardfp/\
stage3-armv7a_hardfp-20161129.tar.bz2
</pre>

As long as we are cross compiling, we use "/usr/$CROSSDEV_TARGET" as working
directory. The cross compiler looks for libraries there and uses many references
to this directory. That's why "/usr/$CROSSDEV_TARGET" will be saved, so it can
be restored after the build.

<pre>
su
umask 0022
tar -cpjf ${CROSSDEV_TARGET}-saved.tar.bz2 -C /usr $CROSSDEV_TARGET
</pre>

Unpack the stage 3 archive into "/usr/$CROSSDEV_TARGET".

<pre>
tar --xattrs --numeric-owner -xpjf stage3-*.tar.bz2 -C /usr/$CROSSDEV_TARGET
</pre>

Sometimes there is a lot of garbage in the "tmp" directory. Remove it.

<pre>
rm -rf /usr/$CROSSDEV_TARGET/tmp/*
</pre>

Exit the root shell and go back to our working directory.

<pre>
exit
</pre>

=== Compile/install kernel ===

The standard Gentoo kernel will not run on the Pandora (or, at least, takes too
much effort to make it run), so download a current kernel from
https://goldelico.com using GIT.

==== Download kernel ====

Download the kernel with GIT.

<pre>
git clone git://git.goldelico.com/gta04-kernel.git
cd gta04-kernel
</pre>

==== Compile kernel ====

Prepare an environment to cross compile the kernel. First call another shell
instance for saving the current environment. This instance is not really
necessary but it is more convenient because the saved environment is restored
after exiting the new shell.

<pre>
bash
umask 0022
export ARCH=arm CROSS_COMPILE=${CROSSDEV_TARGET}-
export PS1="($ARCH) $PS1"
</pre>

The kernel does not support the blue symbols on the keys used by "Fn". To enable
this, patch the kernel using the patch file [[Cross Install Gentoo kernel-patch-Fn-keys.txt|kernel-patch-Fn-keys.txt]].

<pre>
patch -p1 <../kernel-patch-Fn-keys.txt
</pre>

This patches the files "arch/arm/boot/dts/omap3-pandora-common.dtsi" which will
get more key codes for the blue symbols and
"drivers/input/keyboard/twl4030_keypad.c" which will handle the keys.

Now a default configuration for the kernel will be created.

<pre>
make omap2plus_defconfig
</pre>

A lot of configuration must be done to make the kernel work. To ease this use
[[Cross Install Gentoo kernel-config|kernel-config]] which will configure a running
kernel for the Pandora. It uses the name "pherkad" as computer name. Change
this to any name you like in the config file. Calling oldconfig might be
necessary if "kernel-config" is too old for the current gta04-kernel.

<pre>
cp ../kernel-config .config
make oldconfig
make menuconfig
</pre>

In "General setup/Local version" change "-pherkad" to any name you like. But
use "-" as prefix.

Build the kernel and the device tree "omap3-pandora-600mhz.dtb". Pandora users
with 1 GHz units can use "omap3-pandora-1ghz.dts". Use as much CPU cores as you
have for the compiling process.

<pre>
export CPUS="$(grep processor /proc/cpuinfo | wc -l)"
make -j$CPUS zImage
make -j$CPUS modules
make omap3-pandora-600mhz.dtb
</pre>

Convert the kernel into an image for the U-Boot loader. Use any name you
like for "Linux-pherkad".

<pre>
mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008000 -n \
'Linux-pherkad' -d arch/arm/boot/zImage arch/arm/boot/uImage
</pre>

Generate a "boot.scr" file which loads the kernel image and the correct device
tree.

Keep an eye to the bootargs. It uses the following commands:

* Start the systemd as init process: "init=/lib/systemd/systemd".
* Be quiet: "quiet". This can be removed while development.
* Show a splash screen: "splash". There is currently no splash screen, so this
* Use the root file system at: "root=/dev/mmcblk0p2". Take care to use the same partition as described below.
* Use Ext 4 root file system: "rootfstype=ext4".
* Wait for root file system: "rootwait".
* Mount initially read only: "ro". systemd will remount it later as RW.
* Use the following SWAP partition for hibernation/resume: "resume=/dev/mmcblk0p3". This is currently not used.

The file "boot.txt" will be converted to the boot script "boot.src".

<pre>
cat >boot.txt <<EOF
if itest.w *0x4830a204 == 0x102f
then
setenv devicetree omap3-pandora-1ghz
else
setenv devicetree omap3-pandora-600mhz
fi
setenv defaultdisplay lcd
setenv bootargs "init=/lib/systemd/systemd quiet splash \
root=/dev/mmcblk0p2 rootfstype=ext4 rootwait ro resume=/dev/mmcblk0p3"
ext2load mmc 0:1 0x825f0000 /boot/\${devicetree}.dtb
ext2load mmc 0:1 0x80300000 /boot/uImage-pherkad
bootm 0x80300000 - 0x825f0000
EOF

mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n 'Boot script' \
-d boot.txt boot.scr
</pre>

Exit the kernel build environment.

<pre>
exit
</pre>

==== Install kernel ====

The installation of the kernel into the target directory must be done as root.
Create the "boot" directory for the kernel, device tree and boot script and
copy them to the target directory.

<pre>
su
umask 0022
cp arch/arm/boot/uImage /usr/$CROSSDEV_TARGET/boot/uImage-pherkad
cp .config /usr/$CROSSDEV_TARGET/boot/config-pherkad
cp System.map /usr/$CROSSDEV_TARGET/boot/System.map-pherkad
cp arch/arm/boot/dts/omap3-pandora-600mhz.dtb /usr/$CROSSDEV_TARGET/boot/.
cp boot.scr /usr/$CROSSDEV_TARGET/boot/.
</pre>

Create a link for the boot directory. This is used if the boot directory is an
own partition and the boot loader wants to load the kernel from "boot/uImage-*".
In our case it is not really necessary.

<pre>
(cd /usr/$CROSSDEV_TARGET/boot; ln -s . boot)
</pre>

Install all kernel modules into "target/lib/modules". The symbolic link is for
the cross compiling process to find the kernel configuration.

<pre>
make ARCH=arm CROSS_COMPILE=${CROSSDEV_TARGET}- \
INSTALL_MOD_PATH=/usr/$CROSSDEV_TARGET modules_install

(DIR="$PWD"; cd /usr/$CROSSDEV_TARGET/usr/src; ln -s $DIR linux)
cd ..
</pre>

=== Compile system ===

Now it's time to cross compile the whole Gentoo system. The base system is
already installed in the "target" directory. All the binaries there will
be compiled again with our own cross compiler. Also a lot of new packages
(more binaries) will be installed.

==== Prepare cross development system ====

Go to the target and copy all portage configurations from the desktop computer
to the target system, since we want to use the desktop computer system as
base of the Pandora system. This must be done as root.

<pre>
export FROM_DIR="$PWD"
cd /usr/$CROSSDEV_TARGET
</pre>

Edit the "make.conf" file.

<pre>
nano etc/portage/make.conf
</pre>

Change some of the lines there. You might copy some of the contents from
the desktop computer but be sure to have the same CHOST as the CROSSDEV_TARGET.
Especially add or change for the following:

<pre>
CFLAGS="-O2 -pipe -march=armv7-a -mfpu=vfpv3-d16 -mfloat-abi=softfp \
-mfpu=neon -fno-stack-protector"
</pre>

or

<pre>
CFLAGS="-O2 -pipe -march=armv7-a -mfpu=vfpv3-d16 -mfloat-abi=hard \
-mfpu=neon -fno-stack-protector"
</pre>

<pre>

--binpkg-respect-use=y"

GENTOO_MIRRORS="<enter your mirrors>"
PKGDIR="/usr/portage/packages/${CHOST}"
</pre>

It is recommended to activate the build of binary packages. The cross
compilation will fail to build some packages, so QEmu will build all packages
again. It is not necessary to build good cross compiled packages by QEmu again.
Using binary packages will avoid this and save a lot of time.

To avoid mixing up the binary packages of the desktop comuter and the Pandora
set PKGDIR accordingly. Example: "/usr/portage/packages/${CHOST}"

Also copy and edit some package specific files from your desktop computer.

<pre>
cp -r /etc/portage/package.* etc/portage/.
</pre>

Edit the files in "etc/portage/package.*" and configure the portage tree.

<pre>
sed -i "s/amd64/arm/g" etc/portage/package.keywords/*
rm -r etc/portage/package.keywords/cross*
rm -r etc/portage/package.mask/cross*
rm etc/portage/package.use/cross*
rm etc/portage/package.env/cross*

mkdir etc/portage/repos.conf
cp usr/share/portage/config/repos.conf etc/portage/repos.conf/gentoo.conf
rm -f etc/portage/make.profile

(cd etc/portage && \
ln -s /usr/portage/profiles/default/linux/arm/13.0/armv7a/desktop make.profile)
</pre>

Copy the world file from the desktop computer and remove all packages which
should not be installed on the Pandora system.

<pre>
cp /var/lib/portage/world var/lib/portage/world
nano var/lib/portage/world
</pre>

==== Prepare cross-compilation and QEmu environment ====

A lot of packages will fail but we will keep going the emerge process and
compile the failed packages again with QEmu.

But first update the compiler tools in the target system. They will be needed
later in the QEmu environment. If they fail here, try to do it in the QEmu
part.

Copy the static QEmu binary to the target system and set up portage for the
target system.

<pre>
cp /usr/bin/qemu-arm usr/bin/.
mkdir -p usr/portage
touch usr/portage/.keep
</pre>

Do some standard setup for the target system. Copy some personal configurations
to the root account.

<pre>
cp -L /etc/resolv.conf etc/.
cp -r etc/skel/. root/.

cp /root/.bashrc /root/.dir_colors /root/.screenrc /root/.toprc \
/root/.xsession root/.
</pre>

Some nice tools like htop are worth to install them on the Pandora.

<pre>
mkdir -m0700 root/.config
cp -r /root/.config/htop root/.config/.
</pre>

To access the root account with ssh, copy its configuration. This copies the
"id_*" files, also. Don't do this if you deliberately take care about security.

<pre>
cp -r /root/.ssh/. root/.ssh/.
</pre>

==== Start cross compilation ====

Set up a cross compilation environment (use a third shell instance).

<pre>
bash
export CBUILD=x86_64-pc-linux-gnu
export CHOST=$CROSSDEV_TARGET
export ROOT=$PWD
export PORTAGE_CONFIGROOT=$ROOT
export PS1="($CHOST) $PS1"
</pre>

Try to cross compile all packages.

<pre>
$CHOST-emerge -a binutils glibc linux-headers gcc
$CHOST-emerge -a linux-firmware
$CHOST-emerge -ae @world
</pre>

If one of them fails, save the resume list.

<pre>
$CHOST-emerge -p --resume | grep "^\[[eb].*\]" | grep -ve "^\[blocks" | \
cut -b 18- | cut -d " " -f1 | awk '{ print("=" $0); }' >tmp/packages.txt
</pre>

Now go to "Continue cross-compilation with QEmu".

==== Continue cross-compilation with QEmu ====

Enter the chroot environment and emerge the failed package again (the first one
in the packages.txt file).

The portage tree will be mounted into the target system.

In the chroot environment it might be necessary to switch the compiler. Check
if the same version of gcc is used than the cross compiler with
"gcc-config -l". Set the correct version before starting "emerge".

<pre>
mkdir -p $PWD/run/systemd/resolve
cp /run/systemd/resolve/resolv.conf $PWD/run/systemd/resolve/.
mount --rbind /proc $PWD/proc
mount --make-rslave $PWD/proc
mount --rbind /sys $PWD/sys
mount --make-rslave $PWD/sys
mount --rbind /dev $PWD/dev
mount --make-rslave $PWD/dev
mount --rbind /usr/portage $PWD/usr/portage
chroot $PWD /bin/bash
unset CBUILD CHOST ROOT PORTAGE_CONFIGROOT
env-update
source /etc/profile
cd
source ./.bashrc
export PS1="(chroot) $PS1"
emerge -aB1 $(head -1 /tmp/packages.txt)
exit
umount -l usr/portage
umount -l dev sys proc
</pre>

After fixing the failed package(s), continue with the cross compiler.

<pre>
cat tmp/packages.txt | xargs $CHOST-emerge -1
</pre>

If one of them fails again, save the resume list.

<pre>
$CHOST-emerge -p --resume | grep "^\[[eb].*\]" | grep -ve "^\[blocks" | \
cut -b 18- | cut -d " " -f1 | awk '{ print("=" $0); }' >tmp/packages.txt
</pre>

*Go back to "Continue cross-compilation with QEmu" until all packages are merged
successfully.*

Remove some leftover temporary files.

<pre>
rm -rf /var/tmp/portage/* /usr/$CROSSDEV_TARGET/var/tmp/portage/* \
/usr/$CROSSDEV_TARGET/tmp/packages.txt
</pre>

=== Fix lib64-problem ===

Some cross compiled packages install their libraries into the "lib64" directory.
This is not used on the Pandora. So we have to copy all contents from "lib64"
to "lib" and set a link for "lib64".

<pre>
rsync -avc usr/lib64/. usr/lib/.
rm -rf usr/lib64
(cd usr && ln -s lib lib64)
</pre>

=== Configure system ===

Set the key map for Pandora in the console and, as usual in Gentoo,
configure the target system.

Use to make the Pandora keyboard work on the console.
([[Cross Install Gentoo Keymap-pandora.map|keymap-pandora.map]])

And disable the suspend mode for handling the lid switch (this does
currently not work).

<pre>
cp "$FROM_DIR/keymap-pandora.map" etc/.
chmod 644 etc/keymap-pandora.map
echo >etc/vconsole.conf "KEYMAP=/etc/keymap-pandora.map"
echo >>etc/vconsole.conf "FONT=eurlatgr"
sed -i 's/#HandleLidSwitch=suspend/HandleLidSwitch=ignore/g' etc/systemd/logind.conf
</pre>

Set up the mount table. Every line in "etc/fstab" will be commented out and
new entries added. The file system labels are used to mount the partitions.

<pre>
sed -ie "s,^/,#/,g" etc/fstab

cat >>etc/fstab <<EOF
LABEL=phlnx_boot /boot ext2 noatime 1 2
LABEL=phlnx_root / ext4 errors=remount-ro,noatime 1 1
LABEL=phlnx_home /home ext4 noatime,nodev,nosuid 1 2
EOF
</pre>

Enter the chroot environment again.

<pre>
mount --rbind /proc $PWD/proc
mount --make-rslave $PWD/proc
mount --rbind /sys $PWD/sys
mount --make-rslave $PWD/sys
mount --rbind /dev $PWD/dev
mount --make-rslave $PWD/dev
mount --rbind /usr/portage $PWD/usr/portage
chroot $PWD /bin/bash
unset CBUILD CHOST ROOT PORTAGE_CONFIGROOT
env-update
source /etc/profile
cd
source ./.bashrc
export PS1="(chroot) $PS1"
</pre>

Set a password for root.

<pre>
passwd
</pre>

Update the configuration files and read/clear all news from portage.

<pre>
dispatch-conf
eselect news list
eselect news read
eselect news purge
</pre>

Enter the time zone and generate the locale info you want (example: enable all
lines with en_US and de_DE).

<pre>
echo "Europe/Berlin" >/etc/timezone
emerge --config sys-libs/timezone-data
nano -w /etc/locale.gen
locale-gen
</pre>

Use en_US.utf8 (entry #9) as locale.

<pre>
eselect locale list
eselect locale set 9
</pre>

Set up mount table, the machine ID and host name.

<pre>
ln -sf /proc/self/mounts /etc/mtab
systemd-machine-id-setup
echo >/etc/machine-info "PRETTY_HOSTNAME=Pherkad"
echo >/etc/hostname "pherkad"
ln -snf /run/systemd/resolve/resolv.conf /etc/resolv.conf
systemctl enable systemd-resolved.service
</pre>

Exit the chroot environment.

<pre>
exit
umount -l usr/portage
umount -l dev sys proc
</pre>

Remove the QEmu binary. It is not used anymore.

<pre>
rm usr/bin/qemu-arm
</pre>

Also remove some leftovers from the cross compiler and the link to our kernel
sources.

<pre>
rm -f etc/portage/profile/package.provided
rm -f sys-include
rm -f usr/src/linux
</pre>

Copy back the target system and restore the previous cross compiler state.

<pre>
cd "$FROM_DIR"
mkdir $CROSSDEV_TARGET
rsync -a /usr/$CROSSDEV_TARGET/. $CROSSDEV_TARGET/.
rm -rf /usr/$CROSSDEV_TARGET
tar -xpjf ${CROSSDEV_TARGET}-saved.tar.bz2 -C /usr
rm ${CROSSDEV_TARGET}-saved.tar.bz2
</pre>

Exit the root shell.

<pre>
exit
</pre>

= Update system =

To update the system, use a similar approach as in the cross compilation phase.
Define CROSSDEV_TARGET as in "Install cross compiling system".

== Start cross-compilation ==

Set up a cross compilation environment (become root and use a second shell
instance again).

<pre>
cd CrossDev

= Create SD-card partitions phlnx_boot/root/swap/home =

Finally the target system is done. Now it's time to copy it to the Pandora.

== Pandora ==

It's recommended to partition the SD-card for the target system on the Pandora.
Otherwise the boot loader might refuse to work.

Insert the SD-card in the left slot (mmcblk0) and unmount it if necessary.

Create the following partitions:

* A boot partition (ext2).
* A root partition which will contain the target system (at least 4 GB).
* A home partition which we can use later.
* A SWAP partition which we can use later.

<pre>
sudo -s

/sbin/fdisk /dev/mmcblk0
Create new DOS partition label: o
Create new partition: n p 1 Return +8M
Create new partition: n p 2 Return +4G
Create new partition: n p 3 Return +1G
Change partition type: t 3 82 (Linux swap)
Create new partition: n p Return Return
Write all changes: w

/sbin/mkfs.ext2 -FL phlnx_boot /dev/mmcblk0p1
/sbin/mkfs.ext4 -FL phlnx_root -O ^has_journal /dev/mmcblk0p2
/sbin/mkswap -L phlnx_swap /dev/mmcblk0p3
/sbin/mkfs.ext4 -FL phlnx_home -O ^has_journal /dev/mmcblk0p4
exit
</pre>

= Option #1: Copy target system to SD-card =

One of the possibilities to copy the target system to the SD-card on the Pandora
is to use a USB cable connecting the Pandora to the desktop computer.

It's also possible to copy it via the WiFi network (see below).

== Pandora ==

Connect the Pandora via USB to the desktop computer. Insert the SD-card in the
left slot (mmcblk0). Use menu "System/SD-Mass Storage" to access partition
"phlnx_root".

== Desktop computer ==

Mount the root partition and copy the target system. Use the correct "/dev/sd*".

<pre>
su
mkdir /tmp/mnt
mount /dev/sdc /tmp/mnt
mkdir -p /tmp/mnt/boot
touch /tmp/mnt/boot/.keep
mkdir -p /tmp/mnt/home
touch /tmp/mnt/home/.keep

rsync -av --delete --exclude lost+found --exclude /boot \
CrossDev/$CROSSDEV_TARGET/. /tmp/mnt/.

umount /tmp/mnt
</pre>

== Pandora ==

Use "System/SD-Mass Storage" again to access phlnx_boot.

== Desktop computer ==

Mount the boot partition and copy boot directory of the target system.

<pre>
mount /dev/sdc /tmp/mnt
rm -f /tmp/mnt/uImage-pherkad

rsync -av --delete --exclude lost+found \
CrossDev/$CROSSDEV_TARGET/boot/. /tmp/mnt/.

umount /tmp/mnt
rmdir /tmp/mnt
exit
</pre>

== Pandora ==

End SD-Mass Storage.

= Option #2: Copy target system to SD-card via WiFi network =

== Pandora ==

Copy all files from the desktop computer to the SD-card partitions. Use the
same CROSSDEV_TARGET and FROM_DIR environment settings as on the desktop
computer.

<pre>
sudo -s
export REMOTE=mizar.spdns.de
export FROM_DIR=/home/jgeiss/Data/Systems/Pandora/Pherkad/Linux/Gentoo/CrossDev
export CROSSDEV_TARGET=armv7a-hardfloat-linux-gnueabi

mkdir -p /media/phlnx_root/boot
touch /media/phlnx_root/boot/.keep

rsync -av --numeric-ids --delete --exclude lost+found --exclude /boot \
$REMOTE:$FROM_DIR/$CROSSDEV_TARGET/. /media/phlnx_root/.

rsync -av --delete --exclude lost+found \
$REMOTE:$FROM_DIR/$CROSSDEV_TARGET/boot/. /media/phlnx_boot/.

exit
</pre>

= Boot the new system =

Reboot the Pandora and hold the right shoulder button until the boot menu
appears.

'''Sometimes it is necessary to switch off the Pandora for 10-60 seconds.'''

Choose "boot from SD1:1".

It the boot works well, login as root and play around.

== Optional: USB-networking ==

To use networking to the desktop computer via USB cable, execute the
following commands on both systems.

=== Pandora ===

<pre>
modprobe g_ether
ifconfig usb0 192.168.129.3 netmask 255.255.255.0
route add default gw 192.168.129.2
systemctl start sshd
</pre>

=== Desktop computer ===

Configure the corresponding network interface.

<pre>
ifconfig enp0s20u1u1 192.168.129.2 netmask 255.255.255.0
</pre>

Now you should be able to connect to the Pandora.

<pre>
ssh root@192.168.129.3
</pre>

== Shutdown Pandora ==

To shutdown the Pandora system enter the following command.

<pre>
systemctl poweroff
</pre>

= Open issues =

The following things are currently not working and need to be implemented/fixed:

* tw1: not initialized
* omapfb omapfb: no displays, failed to setup omapfb
* omap2_set_init_voltage: unable to find boot up OPP vor ...
* __nand_correct_data: uncorrectable ECC error
* Buffer I/O error on dev mtdblock0, logical block 0, async page read
* Cursor and other GPIO-related keys do not work correctly if CPU is idle. Workaround: echo 1 >/sys/devices/system/cpu/cpu0/cpuidle/state4/disable
* Kernel panic at system shutdown
* fstab: Auto-Mounting /boot or /home causes system suspend after about 30 Seconds.

Cross Install Gentoo

2018-06-08T19:50:27Z

Jgeiss: HandleLidSwitch=ignore added

= Cross install Gentoo Linux on Pandora =

== Introduction ==

These instructions are for installing a recent Gentoo Linux on the OpenPandora
handheld console. The system will be installed and booted from a SD-card. The
Gentoo Linux will be cross-compiled on another desktop computer also running
Gentoo Linux.

It is not necessary to follow all instructions exactly. Some of them can be
changed to your own needs.

'''The system currently supports only the text console and no X11 or sound.'''
'''Also a lot of features are missing.''' See "Open issues" at the end.

=== Prerequisites ===

These instructions assume the following prerequisites:

* Good knowledge in Gentoo Linux.
* A desktop computer running Gentoo Linux. Other Linux is, of course, also possible but requires proper adaption of these instructions.
* An OpenPandora handheld console.
* A SD-card with least 8 GB size.
* A USB cable to connect the Pandora to the desktop computer.

=== Improvement ===

Due to the constant changes of the Linux kernel, GNU software, etc. this
document will be outdated very quick. To avoid this, help is always appreciated
improving this document. If you can update, improve, add or complete this
document, don't hesitate to do so.

== Prepare/install cross compile system ==

To perform the cross-compilation a cross compiler and QEmu must be installed
on the desktop computer. QEmu will help a lot for compiling packages which
will not properly cross compile.

=== Install cross compiling system ===

For compiling software for an ARM controller a cross compiler must be installed.

We can use ARMv7 using either soft float (armv7a-softfp-linux-gnueabi) or hard
float (armv7a-hardfloat-linux-gnueabi).

<pre>export CROSSDEV_TARGET=armv7a-softfp-linux-gnueabi</pre>

or

<pre>export CROSSDEV_TARGET=armv7a-hardfloat-linux-gnueabi</pre>

The additional portage tree in "/usr/local/portage-crossdev" will hold all
information for emerging the cross build system (cross compiler and tools).

To prepare emerging a cross compiler, execute the following commands.

<pre>
su
umask 0022

emerge -av crossdev

mkdir -p /usr/local/portage-crossdev/{profiles,metadata}

echo 'local-crossdev' >/usr/local/portage-crossdev/profiles/repo_name
echo 'masters = gentoo' >/usr/local/portage-crossdev/metadata/layout.conf
echo 'thin-manifests = true' >>/usr/local/portage-crossdev/metadata/layout.conf
chown -R portage:portage /usr/local/portage-crossdev

echo '[local-crossdev]' >/etc/portage/repos.conf/crossdev.conf

echo 'location = /usr/local/portage-crossdev' \
>>/etc/portage/repos.conf/crossdev.conf

echo 'priority = 10' >>/etc/portage/repos.conf/crossdev.conf
echo 'masters = gentoo' >>/etc/portage/repos.conf/crossdev.conf
echo 'auto-sync = no' >>/etc/portage/repos.conf/crossdev.conf
</pre>

The portage tree for emerging the cross build system is set up. Now we have to
find out which versions of the cross build components are about to be installed.
The target system will get binutils, gcc, glibc and linux-headers of a certain
version. The same version should be installed in the cross build system.

<pre>
export BINUTILS_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-devel/binutils/binutils-*.ebuild | tail -1 | \
awk 'match($0, ".*/binutils-(.*).ebuild", v) { print(v[1]); }')

export GCC_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-devel/gcc/gcc-*.ebuild | tail -1 | \
awk 'match($0, ".*/gcc-(.*).ebuild", v) { print(v[1]); }')

export GLIBC_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-libs/glibc/glibc-*.ebuild | tail -1 | \
awk 'match($0, ".*/glibc-(.*).ebuild", v) { print(v[1]); }')

export LINUX_HEADERS_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-kernel/linux-headers/linux-headers-*.ebuild | tail -1 | \
awk 'match($0, ".*/linux-headers-(.*).ebuild", v) { print(v[1]); }')
</pre>

Now emerge the cross compiler.

<pre>
crossdev --binutils $BINUTILS_VER --gcc $GCC_VER --libc $GLIBC_VER \
--kernel $LINUX_HEADERS_VER --target $CROSSDEV_TARGET
</pre>

=== Install QEmu ===

A lot of packages will not cross compile properly. QEmu will help for these
packages. Install it to emulate an ARM controller.

Edit /etc/portage/make.conf.

<pre>
nano /etc/portage/make.conf
</pre>

And add the following lines.

<pre>
QEMU_SOFTMMU_TARGETS=""
QEMU_USER_TARGETS="arm"
</pre>

Also enable the use flag static-user. This builds QEmu as static binary.
QEmu will be used later in a chroot environment of an ARM controller and will
be unable to access needed shared libraries. So it must contain all these
libraries by building it in a static way.

<pre>
euse -E static-user
</pre>

All the needed libraries for QEmu must also be available as library archive
(static libs). Emerging QEmu will request to emerge these libraries as
static variants, also. Create and add these libraries in the file
"/etc/portage/package.use/qemu". Look which libraries are needed.

<pre>
emerge -pv qemu
</pre>

And add them with the use flag static-libs. Here is an Example:

<pre>
>=net-misc/curl-7.53.0 static-libs
>=sys-apps/attr-2.4.47-r2 static-libs
>=media-libs/libsdl-1.2.15-r9 static-libs
>=sys-apps/dtc-1.4.1 static-libs
>=app-arch/bzip2-1.0.6-r7 static-libs
>=x11-libs/pixman-0.34.0 static-libs
>=dev-libs/libpcre-8.40-r1 static-libs
>=sys-libs/libseccomp-2.3.0 static-libs
>=net-fs/libnfs-1.9.7 static-libs
>=dev-libs/cyrus-sasl-2.1.26-r9 static-libs
>=dev-libs/gmp-6.1.0 static-libs
>=dev-libs/libaio-0.3.110 static-libs
>=sys-fs/xfsprogs-4.5.0 static-libs
>=sys-libs/zlib-1.2.11 static-libs
>=media-libs/libjpeg-turbo-1.5.0 static-libs
>=sys-libs/libcap-ng-0.7.8 static-libs
>=dev-libs/openssl-1.0.2k static-libs
>=dev-libs/glib-2.50.3-r1 static-libs
>=virtual/jpeg-0-r2:0 static-libs
>=media-libs/libpng-1.6.27 static-libs
>=sys-libs/ncurses-6.0-r1 static-libs
</pre>

Emerge QEmu.

<pre>
emerge qemu
udevadm trigger -c add /dev/kvm
</pre>

QEmu will execute ARM binaries on the desktop computer as if it would have an
ARM controller. To achieve this, register foreign binaries and start the
systemd service.

<pre>
ln -s /usr/share/qemu/binfmt.d/qemu.conf /etc/binfmt.d/qemu.conf
systemctl start systemd-binfmt
</pre>

Now our desktop computer is able to execute ARM binaries as well as his own
binaries.

=== Install GIT ===

To get the kernel sources, GIT will be needed. Emerge it.

<pre>
emerge git
</pre>

Exit the root shell.

<pre>
exit
</pre>

Now the cross build system is ready to compile a Gentoo Linux for the Pandora.

== Install system ==

=== Prepare target file system ===

To build the system for the Pandora about 10 GB disk space is needed. Create a
directory "CrossDev" to store all data there.

<pre>
mkdir CrossDev
cd CrossDev
</pre>

In this directory two more directories will be created:

* One to store and build the Linux kernel.
* Another will store the whole system for the Pandora including QEmu which is not really a part of the system for Pandora, but it is needed as long as the building process runs.
* Some files and archives.

First get the Gentoo base system "stage3-armv7a-*.tar.bz2". Download it from
a suitable mirror of the Gentoo distribution. See
https://www.gentoo.org/downloads/mirrors for a list of mirrors.

Go to the directory "releases/arm/autobuilds". According to your target, enter

* "current-stage3-armv7a" for soft float (armv7a-softfp-linux-gnueabi),
* "current-stage3-armv7a_hardfp" for hard float (armv7a-hardfloat-linux-gnueabi).

There is a stage 3 file for ARMv7. Download this archive.

Example:

<pre>
wget http://mirror.eu.oneandone.net/linux/distributions/gentoo/gentoo/\
releases/arm/autobuilds/current-stage3-armv7a/stage3-armv7a-20161129.tar.bz2
</pre>

or

<pre>
wget http://mirror.eu.oneandone.net/linux/distributions/gentoo/gentoo/\
releases/arm/autobuilds/current-stage3-armv7a_hardfp/\
stage3-armv7a_hardfp-20161129.tar.bz2
</pre>

As long as we are cross compiling, we use "/usr/$CROSSDEV_TARGET" as working
directory. The cross compiler looks for libraries there and uses many references
to this directory. That's why "/usr/$CROSSDEV_TARGET" will be saved, so it can
be restored after the build.

<pre>
su
umask 0022
tar -cpjf ${CROSSDEV_TARGET}-saved.tar.bz2 -C /usr $CROSSDEV_TARGET
</pre>

Unpack the stage 3 archive into "/usr/$CROSSDEV_TARGET".

<pre>
tar --xattrs --numeric-owner -xpjf stage3-*.tar.bz2 -C /usr/$CROSSDEV_TARGET
</pre>

Sometimes there is a lot of garbage in the "tmp" directory. Remove it.

<pre>
rm -rf /usr/$CROSSDEV_TARGET/tmp/*
</pre>

Exit the root shell and go back to our working directory.

<pre>
exit
</pre>

=== Compile/install kernel ===

The standard Gentoo kernel will not run on the Pandora (or, at least, takes too
much effort to make it run), so download a current kernel from
https://goldelico.com using GIT.

==== Download kernel ====

Download the kernel with GIT.

<pre>
git clone git://git.goldelico.com/gta04-kernel.git
cd gta04-kernel
</pre>

==== Compile kernel ====

Prepare an environment to cross compile the kernel. First call another shell
instance for saving the current environment. This instance is not really
necessary but it is more convenient because the saved environment is restored
after exiting the new shell.

<pre>
bash
umask 0022
export ARCH=arm CROSS_COMPILE=${CROSSDEV_TARGET}-
export PS1="($ARCH) $PS1"
</pre>

The kernel does not support the blue symbols on the keys used by "Fn". To enable
this, patch the kernel using the patch file [[Cross Install Gentoo kernel-patch-Fn-keys.txt|kernel-patch-Fn-keys.txt]].

<pre>
patch -p1 <../kernel-patch-Fn-keys.txt
</pre>

This patches the files "arch/arm/boot/dts/omap3-pandora-common.dtsi" which will
get more key codes for the blue symbols and
"drivers/input/keyboard/twl4030_keypad.c" which will handle the keys.

Now a default configuration for the kernel will be created.

<pre>
make omap2plus_defconfig
</pre>

A lot of configuration must be done to make the kernel work. To ease this use
[[Cross Install Gentoo kernel-config|kernel-config]] which will configure a running
kernel for the Pandora. It uses the name "pherkad" as computer name. Change
this to any name you like in the config file. Calling oldconfig might be
necessary if "kernel-config" is too old for the current gta04-kernel.

<pre>
cp ../kernel-config .config
make oldconfig
make menuconfig
</pre>

In "General setup/Local version" change "-pherkad" to any name you like. But
use "-" as prefix.

Build the kernel and the device tree "omap3-pandora-600mhz.dtb". Pandora users
with 1 GHz units can use "omap3-pandora-1ghz.dts". Use as much CPU cores as you
have for the compiling process.

<pre>
export CPUS="$(grep processor /proc/cpuinfo | wc -l)"
make -j$CPUS zImage
make -j$CPUS modules
make omap3-pandora-600mhz.dtb
</pre>

Convert the kernel into an image for the U-Boot loader. Use any name you
like for "Linux-pherkad".

<pre>
mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008000 -n \
'Linux-pherkad' -d arch/arm/boot/zImage arch/arm/boot/uImage
</pre>

Generate a "boot.scr" file which loads the kernel image and the correct device
tree.

Keep an eye to the bootargs. It uses the following commands:

* Start the systemd as init process: "init=/lib/systemd/systemd".
* Be quiet: "quiet". This can be removed while development.
* Show a splash screen: "splash". There is currently no splash screen, so this
* Use the root file system at: "root=/dev/mmcblk0p2". Take care to use the same partition as described below.
* Use Ext 4 root file system: "rootfstype=ext4".
* Wait for root file system: "rootwait".
* Mount initially read only: "ro". systemd will remount it later as RW.
* Use the following SWAP partition for hibernation/resume: "resume=/dev/mmcblk0p3". This is currently not used.

The file "boot.txt" will be converted to the boot script "boot.src".

<pre>
cat >boot.txt <<EOF
if itest.w *0x4830a204 == 0x102f
then
setenv devicetree omap3-pandora-1ghz
else
setenv devicetree omap3-pandora-600mhz
fi
setenv defaultdisplay lcd
setenv bootargs "init=/lib/systemd/systemd quiet splash \
root=/dev/mmcblk0p2 rootfstype=ext4 rootwait ro resume=/dev/mmcblk0p3"
ext2load mmc 0:1 0x825f0000 /boot/\${devicetree}.dtb
ext2load mmc 0:1 0x80300000 /boot/uImage-pherkad
bootm 0x80300000 - 0x825f0000
EOF

mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n 'Boot script' \
-d boot.txt boot.scr
</pre>

Exit the kernel build environment.

<pre>
exit
</pre>

==== Install kernel ====

The installation of the kernel into the target directory must be done as root.
Create the "boot" directory for the kernel, device tree and boot script and
copy them to the target directory.

<pre>
su
umask 0022
cp arch/arm/boot/uImage /usr/$CROSSDEV_TARGET/boot/uImage-pherkad
cp .config /usr/$CROSSDEV_TARGET/boot/config-pherkad
cp System.map /usr/$CROSSDEV_TARGET/boot/System.map-pherkad
cp arch/arm/boot/dts/omap3-pandora-600mhz.dtb /usr/$CROSSDEV_TARGET/boot/.
cp boot.scr /usr/$CROSSDEV_TARGET/boot/.
</pre>

Create a link for the boot directory. This is used if the boot directory is an
own partition and the boot loader wants to load the kernel from "boot/uImage-*".
In our case it is not really necessary.

<pre>
(cd /usr/$CROSSDEV_TARGET/boot; ln -s . boot)
</pre>

Install all kernel modules into "target/lib/modules". The symbolic link is for
the cross compiling process to find the kernel configuration.

<pre>
make ARCH=arm CROSS_COMPILE=${CROSSDEV_TARGET}- \
INSTALL_MOD_PATH=/usr/$CROSSDEV_TARGET modules_install

(DIR="$PWD"; cd /usr/$CROSSDEV_TARGET/usr/src; ln -s $DIR linux)
cd ..
</pre>

=== Compile system ===

Now it's time to cross compile the whole Gentoo system. The base system is
already installed in the "target" directory. All the binaries there will
be compiled again with our own cross compiler. Also a lot of new packages
(more binaries) will be installed.

==== Prepare cross development system ====

Go to the target and copy all portage configurations from the desktop computer
to the target system, since we want to use the desktop computer system as
base of the Pandora system. This must be done as root.

<pre>
export FROM_DIR="$PWD"
cd /usr/$CROSSDEV_TARGET
</pre>

Edit the "make.conf" file.

<pre>
nano etc/portage/make.conf
</pre>

Change some of the lines there. You might copy some of the contents from
the desktop computer but be sure to have the same CHOST as the CROSSDEV_TARGET.
Especially add or change for the following:

<pre>
CFLAGS="-O2 -pipe -march=armv7-a -mfpu=vfpv3-d16 -mfloat-abi=softfp \
-mfpu=neon -fno-stack-protector"
</pre>

or

<pre>
CFLAGS="-O2 -pipe -march=armv7-a -mfpu=vfpv3-d16 -mfloat-abi=hard \
-mfpu=neon -fno-stack-protector"
</pre>

<pre>

--binpkg-respect-use=y"

GENTOO_MIRRORS="<enter your mirrors>"
PKGDIR="/usr/portage/packages/${CHOST}"
</pre>

It is recommended to activate the build of binary packages. The cross
compilation will fail to build some packages, so QEmu will build all packages
again. It is not necessary to build good cross compiled packages by QEmu again.
Using binary packages will avoid this and save a lot of time.

To avoid mixing up the binary packages of the desktop comuter and the Pandora
set PKGDIR accordingly. Example: "/usr/portage/packages/${CHOST}"

Also copy and edit some package specific files from your desktop computer.

<pre>
cp -r /etc/portage/package.* etc/portage/.
</pre>

Edit the files in "etc/portage/package.*" and configure the portage tree.

<pre>
sed -i "s/amd64/arm/g" etc/portage/package.keywords/*
rm -r etc/portage/package.keywords/cross*
rm -r etc/portage/package.mask/cross*
rm etc/portage/package.use/cross*
rm etc/portage/package.env/cross*

mkdir etc/portage/repos.conf
cp usr/share/portage/config/repos.conf etc/portage/repos.conf/gentoo.conf
rm -f etc/portage/make.profile

(cd etc/portage && \
ln -s /usr/portage/profiles/default/linux/arm/13.0/armv7a/desktop make.profile)
</pre>

Copy the world file from the desktop computer and remove all packages which
should not be installed on the Pandora system.

<pre>
cp /var/lib/portage/world var/lib/portage/world
nano var/lib/portage/world
</pre>

==== Prepare cross-compilation and QEmu environment ====

A lot of packages will fail but we will keep going the emerge process and
compile the failed packages again with QEmu.

But first update the compiler tools in the target system. They will be needed
later in the QEmu environment. If they fail here, try to do it in the QEmu
part.

Copy the static QEmu binary to the target system and set up portage for the
target system.

<pre>
cp /usr/bin/qemu-arm usr/bin/.
mkdir -p usr/portage
touch usr/portage/.keep
</pre>

Do some standard setup for the target system. Copy some personal configurations
to the root account.

<pre>
cp -L /etc/resolv.conf etc/.
cp -r etc/skel/. root/.

cp /root/.bashrc /root/.dir_colors /root/.screenrc /root/.toprc \
/root/.xsession root/.
</pre>

Some nice tools like htop are worth to install them on the Pandora.

<pre>
mkdir -m0700 root/.config
cp -r /root/.config/htop root/.config/.
</pre>

To access the root account with ssh, copy its configuration. This copies the
"id_*" files, also. Don't do this if you deliberately take care about security.

<pre>
cp -r /root/.ssh/. root/.ssh/.
</pre>

==== Start cross compilation ====

Set up a cross compilation environment (use a third shell instance).

<pre>
bash
export CBUILD=x86_64-pc-linux-gnu
export CHOST=$CROSSDEV_TARGET
export ROOT=$PWD
export PORTAGE_CONFIGROOT=$ROOT
export PS1="($CHOST) $PS1"
</pre>

Try to cross compile all packages.

<pre>
$CHOST-emerge -a binutils glibc linux-headers gcc
$CHOST-emerge -a linux-firmware
$CHOST-emerge -ae @world
</pre>

If one of them fails, save the resume list.

<pre>
$CHOST-emerge -p --resume | grep "^\[[eb].*\]" | grep -ve "^\[blocks" | \
cut -b 18- | cut -d " " -f1 | awk '{ print("=" $0); }' >tmp/packages.txt
</pre>

Now go to "Continue cross-compilation with QEmu".

==== Continue cross-compilation with QEmu ====

Enter the chroot environment and emerge the failed package again (the first one
in the packages.txt file).

The portage tree will be mounted into the target system.

In the chroot environment it might be necessary to switch the compiler. Check
if the same version of gcc is used than the cross compiler with
"gcc-config -l". Set the correct version before starting "emerge".

=== Fix lib64-problem ===

Some cross compiled packages install their libraries into the "lib64" directory.
This is not used on the Pandora. So we have to copy all contents from "lib64"
to "lib" and set a link for "lib64".

<pre>
rsync -avc usr/lib64/. usr/lib/.
rm -rf usr/lib64
(cd usr && ln -s lib lib64)
</pre>

=== Configure system ===

Set the key map for Pandora in the console and, as usual in Gentoo,
configure the target system.

Use to make the Pandora keyboard work on the console.
([[Cross Install Gentoo Keymap-pandora.map|keymap-pandora.map]])

And disable the suspend mode for handling the lid switch (this does
currently not work).

<pre>
cp "$FROM_DIR/keymap-pandora.map" etc/.
chmod 644 etc/keymap-pandora.map
echo >etc/vconsole.conf "KEYMAP=/etc/keymap-pandora.map"
echo >>etc/vconsole.conf "FONT=eurlatgr"
sed -i 's/#HandleLidSwitch=suspend/HandleLidSwitch=ignore/g' etc/systemd/logind.conf
</pre>

Set up the mount table. Every line in "etc/fstab" will be commented out and
new entries added. The file system labels are used to mount the partitions.

<pre>
sed -ie "s,^/,#/,g" etc/fstab

cat >>etc/fstab <<EOF

= Create SD-card partitions phlnx_boot/root/swap/home =

Finally the target system is done. Now it's time to copy it to the Pandora.

== Pandora ==

It's recommended to partition the SD-card for the target system on the Pandora.
Otherwise the boot loader might refuse to work.

Insert the SD-card in the left slot (mmcblk0) and unmount it if necessary.

Create the following partitions:

* A boot partition (ext2).
* A root partition which will contain the target system (at least 4 GB).
* A home partition which we can use later.
* A SWAP partition which we can use later.

<pre>
sudo -s

/sbin/fdisk /dev/mmcblk0
Create new DOS partition label: o
Create new partition: n p 1 Return +8M
Create new partition: n p 2 Return +4G
Create new partition: n p 3 Return +1G
Change partition type: t 3 82 (Linux swap)
Create new partition: n p Return Return
Write all changes: w

/sbin/mkfs.ext2 -FL phlnx_boot /dev/mmcblk0p1
/sbin/mkfs.ext4 -FL phlnx_root -O ^has_journal /dev/mmcblk0p2
/sbin/mkswap -L phlnx_swap /dev/mmcblk0p3
/sbin/mkfs.ext4 -FL phlnx_home -O ^has_journal /dev/mmcblk0p4
exit
</pre>

= Option #1: Copy target system to SD-card =

One of the possibilities to copy the target system to the SD-card on the Pandora
is to use a USB cable connecting the Pandora to the desktop computer.

It's also possible to copy it via the WiFi network (see below).

== Pandora ==

Connect the Pandora via USB to the desktop computer. Insert the SD-card in the
left slot (mmcblk0). Use menu "System/SD-Mass Storage" to access partition
"phlnx_root".

== Desktop computer ==

Mount the root partition and copy the target system. Use the correct "/dev/sd*".

<pre>
su
mkdir /tmp/mnt
mount /dev/sdc /tmp/mnt
mkdir -p /tmp/mnt/boot
touch /tmp/mnt/boot/.keep
mkdir -p /tmp/mnt/home
touch /tmp/mnt/home/.keep

rsync -av --delete --exclude lost+found --exclude /boot \
CrossDev/$CROSSDEV_TARGET/. /tmp/mnt/.

umount /tmp/mnt
</pre>

== Pandora ==

Use "System/SD-Mass Storage" again to access phlnx_boot.

== Desktop computer ==

Mount the boot partition and copy boot directory of the target system.

<pre>
mount /dev/sdc /tmp/mnt
rm -f /tmp/mnt/uImage-pherkad

rsync -av --delete --exclude lost+found \
CrossDev/$CROSSDEV_TARGET/boot/. /tmp/mnt/.

umount /tmp/mnt
rmdir /tmp/mnt
exit
</pre>

== Pandora ==

End SD-Mass Storage.

= Option #2: Copy target system to SD-card via WiFi network =

== Pandora ==

Copy all files from the desktop computer to the SD-card partitions. Use the
same CROSSDEV_TARGET and FROM_DIR environment settings as on the desktop
computer.

<pre>
sudo -s
export REMOTE=mizar.spdns.de
export FROM_DIR=/home/jgeiss/Data/Systems/Pandora/Pherkad/Linux/Gentoo/CrossDev
export CROSSDEV_TARGET=armv7a-hardfloat-linux-gnueabi

mkdir -p /media/phlnx_root/boot
touch /media/phlnx_root/boot/.keep

rsync -av --numeric-ids --delete --exclude lost+found --exclude /boot \
$REMOTE:$FROM_DIR/$CROSSDEV_TARGET/. /media/phlnx_root/.

rsync -av --delete --exclude lost+found \
$REMOTE:$FROM_DIR/$CROSSDEV_TARGET/boot/. /media/phlnx_boot/.

exit
</pre>

= Boot the new system =

Reboot the Pandora and hold the right shoulder button until the boot menu
appears.

'''Sometimes it is necessary to switch off the Pandora for 10-60 seconds.'''

Choose "boot from SD1:1".

It the boot works well, login as root and play around.

== Optional: USB-networking ==

To use networking to the desktop computer via USB cable, execute the
following commands on both systems.

=== Pandora ===

<pre>
modprobe g_ether
ifconfig usb0 192.168.129.3 netmask 255.255.255.0
route add default gw 192.168.129.2
systemctl start sshd
</pre>

=== Desktop computer ===

Configure the corresponding network interface.

<pre>
ifconfig enp0s20u1u1 192.168.129.2 netmask 255.255.255.0
</pre>

Now you should be able to connect to the Pandora.

<pre>
ssh root@192.168.129.3
</pre>

== Shutdown Pandora ==

To shutdown the Pandora system enter the following command.

<pre>
systemctl poweroff
</pre>

= Open issues =

The following things are currently not working and need to be implemented/fixed:

* tw1: not initialized
* omapfb omapfb: no displays, failed to setup omapfb
* omap2_set_init_voltage: unable to find boot up OPP vor ...
* __nand_correct_data: uncorrectable ECC error
* Buffer I/O error on dev mtdblock0, logical block 0, async page read
* Cursor and other GPIO-related keys do not work correctly if CPU is idle. Workaround: echo 1 >/sys/devices/system/cpu/cpu0/cpuidle/state4/disable
* Kernel panic at system shutdown
* fstab: Auto-Mounting /boot or /home causes system suspend after about 30 Seconds.

Cross Install Gentoo

2018-06-08T19:41:12Z

Jgeiss: "wl1251 board initialization failed" removed

= Cross install Gentoo Linux on Pandora =

== Introduction ==

These instructions are for installing a recent Gentoo Linux on the OpenPandora
handheld console. The system will be installed and booted from a SD-card. The
Gentoo Linux will be cross-compiled on another desktop computer also running
Gentoo Linux.

It is not necessary to follow all instructions exactly. Some of them can be
changed to your own needs.

'''The system currently supports only the text console and no X11 or sound.'''
'''Also a lot of features are missing.''' See "Open issues" at the end.

=== Prerequisites ===

These instructions assume the following prerequisites:

* Good knowledge in Gentoo Linux.
* A desktop computer running Gentoo Linux. Other Linux is, of course, also possible but requires proper adaption of these instructions.
* An OpenPandora handheld console.
* A SD-card with least 8 GB size.
* A USB cable to connect the Pandora to the desktop computer.

=== Improvement ===

Due to the constant changes of the Linux kernel, GNU software, etc. this
document will be outdated very quick. To avoid this, help is always appreciated
improving this document. If you can update, improve, add or complete this
document, don't hesitate to do so.

== Prepare/install cross compile system ==

To perform the cross-compilation a cross compiler and QEmu must be installed
on the desktop computer. QEmu will help a lot for compiling packages which
will not properly cross compile.

=== Install cross compiling system ===

For compiling software for an ARM controller a cross compiler must be installed.

We can use ARMv7 using either soft float (armv7a-softfp-linux-gnueabi) or hard
float (armv7a-hardfloat-linux-gnueabi).

<pre>export CROSSDEV_TARGET=armv7a-softfp-linux-gnueabi</pre>

or

<pre>export CROSSDEV_TARGET=armv7a-hardfloat-linux-gnueabi</pre>

The additional portage tree in "/usr/local/portage-crossdev" will hold all
information for emerging the cross build system (cross compiler and tools).

To prepare emerging a cross compiler, execute the following commands.

<pre>
su
umask 0022

emerge -av crossdev

mkdir -p /usr/local/portage-crossdev/{profiles,metadata}

echo 'local-crossdev' >/usr/local/portage-crossdev/profiles/repo_name
echo 'masters = gentoo' >/usr/local/portage-crossdev/metadata/layout.conf
echo 'thin-manifests = true' >>/usr/local/portage-crossdev/metadata/layout.conf
chown -R portage:portage /usr/local/portage-crossdev

echo '[local-crossdev]' >/etc/portage/repos.conf/crossdev.conf

echo 'location = /usr/local/portage-crossdev' \
>>/etc/portage/repos.conf/crossdev.conf

echo 'priority = 10' >>/etc/portage/repos.conf/crossdev.conf
echo 'masters = gentoo' >>/etc/portage/repos.conf/crossdev.conf
echo 'auto-sync = no' >>/etc/portage/repos.conf/crossdev.conf
</pre>

The portage tree for emerging the cross build system is set up. Now we have to
find out which versions of the cross build components are about to be installed.
The target system will get binutils, gcc, glibc and linux-headers of a certain
version. The same version should be installed in the cross build system.

<pre>
export BINUTILS_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-devel/binutils/binutils-*.ebuild | tail -1 | \
awk 'match($0, ".*/binutils-(.*).ebuild", v) { print(v[1]); }')

export GCC_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-devel/gcc/gcc-*.ebuild | tail -1 | \
awk 'match($0, ".*/gcc-(.*).ebuild", v) { print(v[1]); }')

export GLIBC_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-libs/glibc/glibc-*.ebuild | tail -1 | \
awk 'match($0, ".*/glibc-(.*).ebuild", v) { print(v[1]); }')

export LINUX_HEADERS_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-kernel/linux-headers/linux-headers-*.ebuild | tail -1 | \
awk 'match($0, ".*/linux-headers-(.*).ebuild", v) { print(v[1]); }')
</pre>

Now emerge the cross compiler.

<pre>
crossdev --binutils $BINUTILS_VER --gcc $GCC_VER --libc $GLIBC_VER \
--kernel $LINUX_HEADERS_VER --target $CROSSDEV_TARGET
</pre>

=== Install QEmu ===

A lot of packages will not cross compile properly. QEmu will help for these
packages. Install it to emulate an ARM controller.

Edit /etc/portage/make.conf.

<pre>
nano /etc/portage/make.conf
</pre>

And add the following lines.

<pre>
QEMU_SOFTMMU_TARGETS=""
QEMU_USER_TARGETS="arm"
</pre>

Also enable the use flag static-user. This builds QEmu as static binary.
QEmu will be used later in a chroot environment of an ARM controller and will
be unable to access needed shared libraries. So it must contain all these
libraries by building it in a static way.

<pre>
euse -E static-user
</pre>

All the needed libraries for QEmu must also be available as library archive
(static libs). Emerging QEmu will request to emerge these libraries as
static variants, also. Create and add these libraries in the file
"/etc/portage/package.use/qemu". Look which libraries are needed.

<pre>
emerge -pv qemu
</pre>

And add them with the use flag static-libs. Here is an Example:

<pre>
>=net-misc/curl-7.53.0 static-libs
>=sys-apps/attr-2.4.47-r2 static-libs
>=media-libs/libsdl-1.2.15-r9 static-libs
>=sys-apps/dtc-1.4.1 static-libs
>=app-arch/bzip2-1.0.6-r7 static-libs
>=x11-libs/pixman-0.34.0 static-libs
>=dev-libs/libpcre-8.40-r1 static-libs
>=sys-libs/libseccomp-2.3.0 static-libs
>=net-fs/libnfs-1.9.7 static-libs
>=dev-libs/cyrus-sasl-2.1.26-r9 static-libs
>=dev-libs/gmp-6.1.0 static-libs
>=dev-libs/libaio-0.3.110 static-libs
>=sys-fs/xfsprogs-4.5.0 static-libs
>=sys-libs/zlib-1.2.11 static-libs
>=media-libs/libjpeg-turbo-1.5.0 static-libs
>=sys-libs/libcap-ng-0.7.8 static-libs
>=dev-libs/openssl-1.0.2k static-libs
>=dev-libs/glib-2.50.3-r1 static-libs
>=virtual/jpeg-0-r2:0 static-libs
>=media-libs/libpng-1.6.27 static-libs
>=sys-libs/ncurses-6.0-r1 static-libs
</pre>

Emerge QEmu.

<pre>
emerge qemu
udevadm trigger -c add /dev/kvm
</pre>

QEmu will execute ARM binaries on the desktop computer as if it would have an
ARM controller. To achieve this, register foreign binaries and start the
systemd service.

<pre>
ln -s /usr/share/qemu/binfmt.d/qemu.conf /etc/binfmt.d/qemu.conf
systemctl start systemd-binfmt
</pre>

Now our desktop computer is able to execute ARM binaries as well as his own
binaries.

=== Install GIT ===

To get the kernel sources, GIT will be needed. Emerge it.

<pre>
emerge git
</pre>

Exit the root shell.

<pre>
exit
</pre>

Now the cross build system is ready to compile a Gentoo Linux for the Pandora.

== Install system ==

=== Prepare target file system ===

To build the system for the Pandora about 10 GB disk space is needed. Create a
directory "CrossDev" to store all data there.

<pre>
mkdir CrossDev
cd CrossDev
</pre>

In this directory two more directories will be created:

* One to store and build the Linux kernel.
* Another will store the whole system for the Pandora including QEmu which is not really a part of the system for Pandora, but it is needed as long as the building process runs.
* Some files and archives.

First get the Gentoo base system "stage3-armv7a-*.tar.bz2". Download it from
a suitable mirror of the Gentoo distribution. See
https://www.gentoo.org/downloads/mirrors for a list of mirrors.

Go to the directory "releases/arm/autobuilds". According to your target, enter

* "current-stage3-armv7a" for soft float (armv7a-softfp-linux-gnueabi),
* "current-stage3-armv7a_hardfp" for hard float (armv7a-hardfloat-linux-gnueabi).

There is a stage 3 file for ARMv7. Download this archive.

Example:

<pre>
wget http://mirror.eu.oneandone.net/linux/distributions/gentoo/gentoo/\
releases/arm/autobuilds/current-stage3-armv7a/stage3-armv7a-20161129.tar.bz2
</pre>

or

<pre>
wget http://mirror.eu.oneandone.net/linux/distributions/gentoo/gentoo/\
releases/arm/autobuilds/current-stage3-armv7a_hardfp/\
stage3-armv7a_hardfp-20161129.tar.bz2
</pre>

As long as we are cross compiling, we use "/usr/$CROSSDEV_TARGET" as working
directory. The cross compiler looks for libraries there and uses many references
to this directory. That's why "/usr/$CROSSDEV_TARGET" will be saved, so it can
be restored after the build.

<pre>
su
umask 0022
tar -cpjf ${CROSSDEV_TARGET}-saved.tar.bz2 -C /usr $CROSSDEV_TARGET
</pre>

Unpack the stage 3 archive into "/usr/$CROSSDEV_TARGET".

<pre>
tar --xattrs --numeric-owner -xpjf stage3-*.tar.bz2 -C /usr/$CROSSDEV_TARGET
</pre>

Sometimes there is a lot of garbage in the "tmp" directory. Remove it.

<pre>
rm -rf /usr/$CROSSDEV_TARGET/tmp/*
</pre>

Exit the root shell and go back to our working directory.

<pre>
exit
</pre>

=== Compile/install kernel ===

The standard Gentoo kernel will not run on the Pandora (or, at least, takes too
much effort to make it run), so download a current kernel from
https://goldelico.com using GIT.

==== Download kernel ====

Download the kernel with GIT.

<pre>
git clone git://git.goldelico.com/gta04-kernel.git
cd gta04-kernel
</pre>

==== Compile kernel ====

Prepare an environment to cross compile the kernel. First call another shell
instance for saving the current environment. This instance is not really
necessary but it is more convenient because the saved environment is restored
after exiting the new shell.

<pre>
bash
umask 0022
export ARCH=arm CROSS_COMPILE=${CROSSDEV_TARGET}-
export PS1="($ARCH) $PS1"
</pre>

The kernel does not support the blue symbols on the keys used by "Fn". To enable
this, patch the kernel using the patch file [[Cross Install Gentoo kernel-patch-Fn-keys.txt|kernel-patch-Fn-keys.txt]].

<pre>
patch -p1 <../kernel-patch-Fn-keys.txt
</pre>

This patches the files "arch/arm/boot/dts/omap3-pandora-common.dtsi" which will
get more key codes for the blue symbols and
"drivers/input/keyboard/twl4030_keypad.c" which will handle the keys.

Now a default configuration for the kernel will be created.

<pre>
make omap2plus_defconfig
</pre>

A lot of configuration must be done to make the kernel work. To ease this use
[[Cross Install Gentoo kernel-config|kernel-config]] which will configure a running
kernel for the Pandora. It uses the name "pherkad" as computer name. Change
this to any name you like in the config file. Calling oldconfig might be
necessary if "kernel-config" is too old for the current gta04-kernel.

<pre>
cp ../kernel-config .config
make oldconfig
make menuconfig
</pre>

In "General setup/Local version" change "-pherkad" to any name you like. But
use "-" as prefix.

Build the kernel and the device tree "omap3-pandora-600mhz.dtb". Pandora users
with 1 GHz units can use "omap3-pandora-1ghz.dts". Use as much CPU cores as you
have for the compiling process.

<pre>
export CPUS="$(grep processor /proc/cpuinfo | wc -l)"
make -j$CPUS zImage
make -j$CPUS modules
make omap3-pandora-600mhz.dtb
</pre>

Convert the kernel into an image for the U-Boot loader. Use any name you
like for "Linux-pherkad".

<pre>
mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008000 -n \
'Linux-pherkad' -d arch/arm/boot/zImage arch/arm/boot/uImage
</pre>

Generate a "boot.scr" file which loads the kernel image and the correct device
tree.

Keep an eye to the bootargs. It uses the following commands:

* Start the systemd as init process: "init=/lib/systemd/systemd".
* Be quiet: "quiet". This can be removed while development.
* Show a splash screen: "splash". There is currently no splash screen, so this
* Use the root file system at: "root=/dev/mmcblk0p2". Take care to use the same partition as described below.
* Use Ext 4 root file system: "rootfstype=ext4".
* Wait for root file system: "rootwait".
* Mount initially read only: "ro". systemd will remount it later as RW.
* Use the following SWAP partition for hibernation/resume: "resume=/dev/mmcblk0p3". This is currently not used.

The file "boot.txt" will be converted to the boot script "boot.src".

<pre>
cat >boot.txt <<EOF
if itest.w *0x4830a204 == 0x102f
then
setenv devicetree omap3-pandora-1ghz
else
setenv devicetree omap3-pandora-600mhz
fi
setenv defaultdisplay lcd
setenv bootargs "init=/lib/systemd/systemd quiet splash \
root=/dev/mmcblk0p2 rootfstype=ext4 rootwait ro resume=/dev/mmcblk0p3"
ext2load mmc 0:1 0x825f0000 /boot/\${devicetree}.dtb
ext2load mmc 0:1 0x80300000 /boot/uImage-pherkad
bootm 0x80300000 - 0x825f0000
EOF

mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n 'Boot script' \
-d boot.txt boot.scr
</pre>

Exit the kernel build environment.

<pre>
exit
</pre>

==== Install kernel ====

The installation of the kernel into the target directory must be done as root.
Create the "boot" directory for the kernel, device tree and boot script and
copy them to the target directory.

<pre>
su
umask 0022
cp arch/arm/boot/uImage /usr/$CROSSDEV_TARGET/boot/uImage-pherkad
cp .config /usr/$CROSSDEV_TARGET/boot/config-pherkad
cp System.map /usr/$CROSSDEV_TARGET/boot/System.map-pherkad
cp arch/arm/boot/dts/omap3-pandora-600mhz.dtb /usr/$CROSSDEV_TARGET/boot/.
cp boot.scr /usr/$CROSSDEV_TARGET/boot/.
</pre>

Create a link for the boot directory. This is used if the boot directory is an
own partition and the boot loader wants to load the kernel from "boot/uImage-*".
In our case it is not really necessary.

<pre>
(cd /usr/$CROSSDEV_TARGET/boot; ln -s . boot)
</pre>

Install all kernel modules into "target/lib/modules". The symbolic link is for
the cross compiling process to find the kernel configuration.

<pre>
make ARCH=arm CROSS_COMPILE=${CROSSDEV_TARGET}- \
INSTALL_MOD_PATH=/usr/$CROSSDEV_TARGET modules_install

(DIR="$PWD"; cd /usr/$CROSSDEV_TARGET/usr/src; ln -s $DIR linux)
cd ..
</pre>

=== Compile system ===

Now it's time to cross compile the whole Gentoo system. The base system is
already installed in the "target" directory. All the binaries there will
be compiled again with our own cross compiler. Also a lot of new packages
(more binaries) will be installed.

==== Prepare cross development system ====

Go to the target and copy all portage configurations from the desktop computer
to the target system, since we want to use the desktop computer system as
base of the Pandora system. This must be done as root.

<pre>
export FROM_DIR="$PWD"
cd /usr/$CROSSDEV_TARGET
</pre>

Edit the "make.conf" file.

<pre>
nano etc/portage/make.conf
</pre>

Change some of the lines there. You might copy some of the contents from
the desktop computer but be sure to have the same CHOST as the CROSSDEV_TARGET.
Especially add or change for the following:

<pre>
CFLAGS="-O2 -pipe -march=armv7-a -mfpu=vfpv3-d16 -mfloat-abi=softfp \
-mfpu=neon -fno-stack-protector"
</pre>

or

<pre>
CFLAGS="-O2 -pipe -march=armv7-a -mfpu=vfpv3-d16 -mfloat-abi=hard \
-mfpu=neon -fno-stack-protector"
</pre>

<pre>

--binpkg-respect-use=y"

GENTOO_MIRRORS="<enter your mirrors>"
PKGDIR="/usr/portage/packages/${CHOST}"
</pre>

It is recommended to activate the build of binary packages. The cross
compilation will fail to build some packages, so QEmu will build all packages
again. It is not necessary to build good cross compiled packages by QEmu again.
Using binary packages will avoid this and save a lot of time.

To avoid mixing up the binary packages of the desktop comuter and the Pandora
set PKGDIR accordingly. Example: "/usr/portage/packages/${CHOST}"

Also copy and edit some package specific files from your desktop computer.

<pre>
cp -r /etc/portage/package.* etc/portage/.
</pre>

Edit the files in "etc/portage/package.*" and configure the portage tree.

<pre>
sed -i "s/amd64/arm/g" etc/portage/package.keywords/*
rm -r etc/portage/package.keywords/cross*
rm -r etc/portage/package.mask/cross*
rm etc/portage/package.use/cross*
rm etc/portage/package.env/cross*

mkdir etc/portage/repos.conf
cp usr/share/portage/config/repos.conf etc/portage/repos.conf/gentoo.conf
rm -f etc/portage/make.profile

(cd etc/portage && \
ln -s /usr/portage/profiles/default/linux/arm/13.0/armv7a/desktop make.profile)
</pre>

Copy the world file from the desktop computer and remove all packages which
should not be installed on the Pandora system.

<pre>
cp /var/lib/portage/world var/lib/portage/world
nano var/lib/portage/world
</pre>

==== Prepare cross-compilation and QEmu environment ====

A lot of packages will fail but we will keep going the emerge process and
compile the failed packages again with QEmu.

But first update the compiler tools in the target system. They will be needed
later in the QEmu environment. If they fail here, try to do it in the QEmu
part.

Copy the static QEmu binary to the target system and set up portage for the
target system.

<pre>
cp /usr/bin/qemu-arm usr/bin/.
mkdir -p usr/portage
touch usr/portage/.keep
</pre>

Do some standard setup for the target system. Copy some personal configurations
to the root account.

<pre>
cp -L /etc/resolv.conf etc/.
cp -r etc/skel/. root/.

cp /root/.bashrc /root/.dir_colors /root/.screenrc /root/.toprc \
/root/.xsession root/.
</pre>

Some nice tools like htop are worth to install them on the Pandora.

<pre>
mkdir -m0700 root/.config
cp -r /root/.config/htop root/.config/.
</pre>

To access the root account with ssh, copy its configuration. This copies the
"id_*" files, also. Don't do this if you deliberately take care about security.

<pre>
cp -r /root/.ssh/. root/.ssh/.
</pre>

==== Start cross compilation ====

Set up a cross compilation environment (use a third shell instance).

<pre>
bash
export CBUILD=x86_64-pc-linux-gnu
export CHOST=$CROSSDEV_TARGET
export ROOT=$PWD
export PORTAGE_CONFIGROOT=$ROOT
export PS1="($CHOST) $PS1"
</pre>

Try to cross compile all packages.

<pre>
$CHOST-emerge -a binutils glibc linux-headers gcc
$CHOST-emerge -a linux-firmware
$CHOST-emerge -ae @world
</pre>

If one of them fails, save the resume list.

<pre>
$CHOST-emerge -p --resume | grep "^\[[eb].*\]" | grep -ve "^\[blocks" | \
cut -b 18- | cut -d " " -f1 | awk '{ print("=" $0); }' >tmp/packages.txt
</pre>

Now go to "Continue cross-compilation with QEmu".

==== Continue cross-compilation with QEmu ====

Enter the chroot environment and emerge the failed package again (the first one
in the packages.txt file).

The portage tree will be mounted into the target system.

In the chroot environment it might be necessary to switch the compiler. Check
if the same version of gcc is used than the cross compiler with
"gcc-config -l". Set the correct version before starting "emerge".

<pre>
mkdir -p $PWD/run/systemd/resolve
cp /run/systemd/resolve/resolv.conf $PWD/run/systemd/resolve/.
mount --rbind /proc $PWD/proc
mount --make-rslave $PWD/proc
mount --rbind /sys $PWD/sys
mount --make-rslave $PWD/sys
mount --rbind /dev $PWD/dev
mount --make-rslave $PWD/dev
mount --rbind /usr/portage $PWD/usr/portage
chroot $PWD /bin/bash
unset CBUILD CHOST ROOT PORTAGE_CONFIGROOT
env-update
source /etc/profile
cd
source ./.bashrc
export PS1="(chroot) $PS1"
emerge -aB1 $(head -1 /tmp/packages.txt)
exit
umount -l usr/portage
umount -l dev sys proc
</pre>

After fixing the failed package(s), continue with the cross compiler.

<pre>
cat tmp/packages.txt | xargs $CHOST-emerge -1
</pre>

If one of them fails again, save the resume list.

<pre>
$CHOST-emerge -p --resume | grep "^\[[eb].*\]" | grep -ve "^\[blocks" | \
cut -b 18- | cut -d " " -f1 | awk '{ print("=" $0); }' >tmp/packages.txt
</pre>

*Go back to "Continue cross-compilation with QEmu" until all packages are merged
successfully.*

Remove some leftover temporary files.

<pre>
rm -rf /var/tmp/portage/* /usr/$CROSSDEV_TARGET/var/tmp/portage/* \
/usr/$CROSSDEV_TARGET/tmp/packages.txt
</pre>

=== Fix lib64-problem ===

Some cross compiled packages install their libraries into the "lib64" directory.
This is not used on the Pandora. So we have to copy all contents from "lib64"
to "lib" and set a link for "lib64".

<pre>
rsync -avc usr/lib64/. usr/lib/.
rm -rf usr/lib64
(cd usr && ln -s lib lib64)
</pre>

=== Configure system ===

Set the key map for Pandora in the console and, as usual in Gentoo,
configure the target system.

Use to make the Pandora keyboard work on the console.
([[Cross Install Gentoo Keymap-pandora.map|keymap-pandora.map]])

<pre>
cp "$FROM_DIR/keymap-pandora.map" etc/.
chmod 644 etc/keymap-pandora.map
echo >etc/vconsole.conf "KEYMAP=/etc/keymap-pandora.map"
echo >>etc/vconsole.conf "FONT=eurlatgr"
</pre>

Set up the mount table. Every line in "etc/fstab" will be commented out and
new entries added. The file system labels are used to mount the partitions.

<pre>
sed -ie "s,^/,#/,g" etc/fstab

cat >>etc/fstab <<EOF
LABEL=phlnx_boot /boot ext2 noauto,noatime 1 2
LABEL=phlnx_root / ext4 errors=remount-ro,noatime 1 1
LABEL=phlnx_home /home ext4 noauto,noatime,nodev,nosuid 1 2
EOF
</pre>

Enter the chroot environment again.

<pre>
mount --rbind /proc $PWD/proc
mount --make-rslave $PWD/proc
mount --rbind /sys $PWD/sys
mount --make-rslave $PWD/sys
mount --rbind /dev $PWD/dev

chroot $PWD /bin/bash
unset CBUILD CHOST ROOT PORTAGE_CONFIGROOT
env-update
source /etc/profile
cd
source ./.bashrc
export PS1="(chroot) $PS1"
</pre>

Set a password for root.

<pre>
passwd
</pre>

Update the configuration files and read/clear all news from portage.

<pre>
dispatch-conf
eselect news list
eselect news read
eselect news purge
</pre>

Enter the time zone and generate the locale info you want (example: enable all
lines with en_US and de_DE).

<pre>
echo "Europe/Berlin" >/etc/timezone
emerge --config sys-libs/timezone-data
nano -w /etc/locale.gen
locale-gen
</pre>

Use en_US.utf8 (entry #9) as locale.

<pre>
eselect locale list
eselect locale set 9
</pre>

Set up mount table, the machine ID and host name.

<pre>
ln -sf /proc/self/mounts /etc/mtab
systemd-machine-id-setup
echo >/etc/machine-info "PRETTY_HOSTNAME=Pherkad"
echo >/etc/hostname "pherkad"
ln -snf /run/systemd/resolve/resolv.conf /etc/resolv.conf
systemctl enable systemd-resolved.service
</pre>

Exit the chroot environment.

<pre>
exit
umount -l usr/portage
umount -l dev sys proc
</pre>

Remove the QEmu binary. It is not used anymore.

<pre>
rm usr/bin/qemu-arm
</pre>

Also remove some leftovers from the cross compiler and the link to our kernel
sources.

<pre>
rm -f etc/portage/profile/package.provided
rm -f sys-include
rm -f usr/src/linux
</pre>

Copy back the target system and restore the previous cross compiler state.

<pre>
cd "$FROM_DIR"
mkdir $CROSSDEV_TARGET
rsync -a /usr/$CROSSDEV_TARGET/. $CROSSDEV_TARGET/.
rm -rf /usr/$CROSSDEV_TARGET
tar -xpjf ${CROSSDEV_TARGET}-saved.tar.bz2 -C /usr
rm ${CROSSDEV_TARGET}-saved.tar.bz2
</pre>

Exit the root shell.

<pre>
exit
</pre>

= Update system =

To update the system, use a similar approach as in the cross compilation phase.
Define CROSSDEV_TARGET as in "Install cross compiling system".

== Start cross-compilation ==

Set up a cross compilation environment (become root and use a second shell
instance again).

<pre>
cd CrossDev

It's recommended to partition the SD-card for the target system on the Pandora.
Otherwise the boot loader might refuse to work.

Insert the SD-card in the left slot (mmcblk0) and unmount it if necessary.

Create the following partitions:

* A boot partition (ext2).
* A root partition which will contain the target system (at least 4 GB).
* A home partition which we can use later.
* A SWAP partition which we can use later.

= Option #1: Copy target system to SD-card =

One of the possibilities to copy the target system to the SD-card on the Pandora
is to use a USB cable connecting the Pandora to the desktop computer.

It's also possible to copy it via the WiFi network (see below).

== Pandora ==

Connect the Pandora via USB to the desktop computer. Insert the SD-card in the
left slot (mmcblk0). Use menu "System/SD-Mass Storage" to access partition
"phlnx_root".

== Desktop computer ==

Mount the root partition and copy the target system. Use the correct "/dev/sd*".

<pre>
su
mkdir /tmp/mnt
mount /dev/sdc /tmp/mnt
mkdir -p /tmp/mnt/boot
touch /tmp/mnt/boot/.keep
mkdir -p /tmp/mnt/home
touch /tmp/mnt/home/.keep

rsync -av --delete --exclude lost+found --exclude /boot \
CrossDev/$CROSSDEV_TARGET/. /tmp/mnt/.

umount /tmp/mnt
</pre>

== Pandora ==

Use "System/SD-Mass Storage" again to access phlnx_boot.

== Desktop computer ==

Mount the boot partition and copy boot directory of the target system.

<pre>
mount /dev/sdc /tmp/mnt
rm -f /tmp/mnt/uImage-pherkad

rsync -av --delete --exclude lost+found \
CrossDev/$CROSSDEV_TARGET/boot/. /tmp/mnt/.

umount /tmp/mnt
rmdir /tmp/mnt
exit
</pre>

== Pandora ==

End SD-Mass Storage.

= Option #2: Copy target system to SD-card via WiFi network =

== Pandora ==

Copy all files from the desktop computer to the SD-card partitions. Use the
same CROSSDEV_TARGET and FROM_DIR environment settings as on the desktop
computer.

<pre>
sudo -s
export REMOTE=mizar.spdns.de
export FROM_DIR=/home/jgeiss/Data/Systems/Pandora/Pherkad/Linux/Gentoo/CrossDev
export CROSSDEV_TARGET=armv7a-hardfloat-linux-gnueabi

mkdir -p /media/phlnx_root/boot
touch /media/phlnx_root/boot/.keep

rsync -av --numeric-ids --delete --exclude lost+found --exclude /boot \
$REMOTE:$FROM_DIR/$CROSSDEV_TARGET/. /media/phlnx_root/.

rsync -av --delete --exclude lost+found \
$REMOTE:$FROM_DIR/$CROSSDEV_TARGET/boot/. /media/phlnx_boot/.

exit
</pre>

= Boot the new system =

Reboot the Pandora and hold the right shoulder button until the boot menu
appears.

'''Sometimes it is necessary to switch off the Pandora for 10-60 seconds.'''

Choose "boot from SD1:1".

It the boot works well, login as root and play around.

== Optional: USB-networking ==

To use networking to the desktop computer via USB cable, execute the
following commands on both systems.

=== Pandora ===

<pre>
modprobe g_ether
ifconfig usb0 192.168.129.3 netmask 255.255.255.0
route add default gw 192.168.129.2
systemctl start sshd
</pre>

=== Desktop computer ===

Configure the corresponding network interface.

<pre>
ifconfig enp0s20u1u1 192.168.129.2 netmask 255.255.255.0
</pre>

Now you should be able to connect to the Pandora.

<pre>
ssh root@192.168.129.3
</pre>

== Shutdown Pandora ==

To shutdown the Pandora system enter the following command.

<pre>
systemctl poweroff
</pre>

= Open issues =

The following things are currently not working and need to be implemented/fixed:

* tw1: not initialized
* omapfb omapfb: no displays, failed to setup omapfb
* omap2_set_init_voltage: unable to find boot up OPP vor ...
* __nand_correct_data: uncorrectable ECC error
* Buffer I/O error on dev mtdblock0, logical block 0, async page read
* Cursor and other GPIO-related keys do not work correctly if CPU is idle. Workaround: echo 1 >/sys/devices/system/cpu/cpu0/cpuidle/state4/disable
* Kernel panic at system shutdown
* fstab: Auto-Mounting /boot or /home causes system suspend after about 30 Seconds.

Cross Install Gentoo

2018-06-08T19:40:15Z

Jgeiss: Emering linux-firmware for WiFi added

= Cross install Gentoo Linux on Pandora =

== Introduction ==

These instructions are for installing a recent Gentoo Linux on the OpenPandora
handheld console. The system will be installed and booted from a SD-card. The
Gentoo Linux will be cross-compiled on another desktop computer also running
Gentoo Linux.

It is not necessary to follow all instructions exactly. Some of them can be
changed to your own needs.

'''The system currently supports only the text console and no X11 or sound.'''
'''Also a lot of features are missing.''' See "Open issues" at the end.

=== Prerequisites ===

These instructions assume the following prerequisites:

* Good knowledge in Gentoo Linux.
* A desktop computer running Gentoo Linux. Other Linux is, of course, also possible but requires proper adaption of these instructions.
* An OpenPandora handheld console.
* A SD-card with least 8 GB size.
* A USB cable to connect the Pandora to the desktop computer.

=== Improvement ===

Due to the constant changes of the Linux kernel, GNU software, etc. this
document will be outdated very quick. To avoid this, help is always appreciated
improving this document. If you can update, improve, add or complete this
document, don't hesitate to do so.

== Prepare/install cross compile system ==

To perform the cross-compilation a cross compiler and QEmu must be installed
on the desktop computer. QEmu will help a lot for compiling packages which
will not properly cross compile.

=== Install cross compiling system ===

For compiling software for an ARM controller a cross compiler must be installed.

We can use ARMv7 using either soft float (armv7a-softfp-linux-gnueabi) or hard
float (armv7a-hardfloat-linux-gnueabi).

<pre>export CROSSDEV_TARGET=armv7a-softfp-linux-gnueabi</pre>

or

<pre>export CROSSDEV_TARGET=armv7a-hardfloat-linux-gnueabi</pre>

The additional portage tree in "/usr/local/portage-crossdev" will hold all
information for emerging the cross build system (cross compiler and tools).

To prepare emerging a cross compiler, execute the following commands.

<pre>
su
umask 0022

emerge -av crossdev

mkdir -p /usr/local/portage-crossdev/{profiles,metadata}

echo 'local-crossdev' >/usr/local/portage-crossdev/profiles/repo_name
echo 'masters = gentoo' >/usr/local/portage-crossdev/metadata/layout.conf
echo 'thin-manifests = true' >>/usr/local/portage-crossdev/metadata/layout.conf
chown -R portage:portage /usr/local/portage-crossdev

echo '[local-crossdev]' >/etc/portage/repos.conf/crossdev.conf

echo 'location = /usr/local/portage-crossdev' \
>>/etc/portage/repos.conf/crossdev.conf

echo 'priority = 10' >>/etc/portage/repos.conf/crossdev.conf
echo 'masters = gentoo' >>/etc/portage/repos.conf/crossdev.conf
echo 'auto-sync = no' >>/etc/portage/repos.conf/crossdev.conf
</pre>

The portage tree for emerging the cross build system is set up. Now we have to
find out which versions of the cross build components are about to be installed.
The target system will get binutils, gcc, glibc and linux-headers of a certain
version. The same version should be installed in the cross build system.

<pre>
export BINUTILS_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-devel/binutils/binutils-*.ebuild | tail -1 | \
awk 'match($0, ".*/binutils-(.*).ebuild", v) { print(v[1]); }')

export GCC_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-devel/gcc/gcc-*.ebuild | tail -1 | \
awk 'match($0, ".*/gcc-(.*).ebuild", v) { print(v[1]); }')

export GLIBC_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-libs/glibc/glibc-*.ebuild | tail -1 | \
awk 'match($0, ".*/glibc-(.*).ebuild", v) { print(v[1]); }')

export LINUX_HEADERS_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-kernel/linux-headers/linux-headers-*.ebuild | tail -1 | \
awk 'match($0, ".*/linux-headers-(.*).ebuild", v) { print(v[1]); }')
</pre>

Now emerge the cross compiler.

<pre>
crossdev --binutils $BINUTILS_VER --gcc $GCC_VER --libc $GLIBC_VER \
--kernel $LINUX_HEADERS_VER --target $CROSSDEV_TARGET
</pre>

=== Install QEmu ===

A lot of packages will not cross compile properly. QEmu will help for these
packages. Install it to emulate an ARM controller.

Edit /etc/portage/make.conf.

<pre>
nano /etc/portage/make.conf
</pre>

And add the following lines.

<pre>
QEMU_SOFTMMU_TARGETS=""
QEMU_USER_TARGETS="arm"
</pre>

Also enable the use flag static-user. This builds QEmu as static binary.
QEmu will be used later in a chroot environment of an ARM controller and will
be unable to access needed shared libraries. So it must contain all these
libraries by building it in a static way.

<pre>
euse -E static-user
</pre>

All the needed libraries for QEmu must also be available as library archive
(static libs). Emerging QEmu will request to emerge these libraries as
static variants, also. Create and add these libraries in the file
"/etc/portage/package.use/qemu". Look which libraries are needed.

<pre>
emerge -pv qemu
</pre>

And add them with the use flag static-libs. Here is an Example:

<pre>
>=net-misc/curl-7.53.0 static-libs
>=sys-apps/attr-2.4.47-r2 static-libs
>=media-libs/libsdl-1.2.15-r9 static-libs
>=sys-apps/dtc-1.4.1 static-libs
>=app-arch/bzip2-1.0.6-r7 static-libs
>=x11-libs/pixman-0.34.0 static-libs
>=dev-libs/libpcre-8.40-r1 static-libs
>=sys-libs/libseccomp-2.3.0 static-libs
>=net-fs/libnfs-1.9.7 static-libs
>=dev-libs/cyrus-sasl-2.1.26-r9 static-libs
>=dev-libs/gmp-6.1.0 static-libs
>=dev-libs/libaio-0.3.110 static-libs
>=sys-fs/xfsprogs-4.5.0 static-libs
>=sys-libs/zlib-1.2.11 static-libs
>=media-libs/libjpeg-turbo-1.5.0 static-libs
>=sys-libs/libcap-ng-0.7.8 static-libs
>=dev-libs/openssl-1.0.2k static-libs
>=dev-libs/glib-2.50.3-r1 static-libs
>=virtual/jpeg-0-r2:0 static-libs
>=media-libs/libpng-1.6.27 static-libs
>=sys-libs/ncurses-6.0-r1 static-libs
</pre>

Emerge QEmu.

<pre>
emerge qemu
udevadm trigger -c add /dev/kvm
</pre>

QEmu will execute ARM binaries on the desktop computer as if it would have an
ARM controller. To achieve this, register foreign binaries and start the
systemd service.

<pre>
ln -s /usr/share/qemu/binfmt.d/qemu.conf /etc/binfmt.d/qemu.conf
systemctl start systemd-binfmt
</pre>

Now our desktop computer is able to execute ARM binaries as well as his own
binaries.

=== Install GIT ===

To get the kernel sources, GIT will be needed. Emerge it.

<pre>
emerge git
</pre>

Exit the root shell.

<pre>
exit
</pre>

Now the cross build system is ready to compile a Gentoo Linux for the Pandora.

== Install system ==

=== Prepare target file system ===

To build the system for the Pandora about 10 GB disk space is needed. Create a
directory "CrossDev" to store all data there.

<pre>
mkdir CrossDev
cd CrossDev
</pre>

In this directory two more directories will be created:

* One to store and build the Linux kernel.
* Another will store the whole system for the Pandora including QEmu which is not really a part of the system for Pandora, but it is needed as long as the building process runs.
* Some files and archives.

First get the Gentoo base system "stage3-armv7a-*.tar.bz2". Download it from
a suitable mirror of the Gentoo distribution. See
https://www.gentoo.org/downloads/mirrors for a list of mirrors.

Go to the directory "releases/arm/autobuilds". According to your target, enter

* "current-stage3-armv7a" for soft float (armv7a-softfp-linux-gnueabi),
* "current-stage3-armv7a_hardfp" for hard float (armv7a-hardfloat-linux-gnueabi).

There is a stage 3 file for ARMv7. Download this archive.

Example:

<pre>
wget http://mirror.eu.oneandone.net/linux/distributions/gentoo/gentoo/\
releases/arm/autobuilds/current-stage3-armv7a/stage3-armv7a-20161129.tar.bz2
</pre>

or

<pre>
wget http://mirror.eu.oneandone.net/linux/distributions/gentoo/gentoo/\
releases/arm/autobuilds/current-stage3-armv7a_hardfp/\
stage3-armv7a_hardfp-20161129.tar.bz2
</pre>

As long as we are cross compiling, we use "/usr/$CROSSDEV_TARGET" as working
directory. The cross compiler looks for libraries there and uses many references
to this directory. That's why "/usr/$CROSSDEV_TARGET" will be saved, so it can
be restored after the build.

<pre>
su
umask 0022
tar -cpjf ${CROSSDEV_TARGET}-saved.tar.bz2 -C /usr $CROSSDEV_TARGET
</pre>

Unpack the stage 3 archive into "/usr/$CROSSDEV_TARGET".

<pre>
tar --xattrs --numeric-owner -xpjf stage3-*.tar.bz2 -C /usr/$CROSSDEV_TARGET
</pre>

Sometimes there is a lot of garbage in the "tmp" directory. Remove it.

<pre>
rm -rf /usr/$CROSSDEV_TARGET/tmp/*
</pre>

Exit the root shell and go back to our working directory.

<pre>
exit
</pre>

=== Compile/install kernel ===

The standard Gentoo kernel will not run on the Pandora (or, at least, takes too
much effort to make it run), so download a current kernel from
https://goldelico.com using GIT.

==== Download kernel ====

Download the kernel with GIT.

<pre>
git clone git://git.goldelico.com/gta04-kernel.git
cd gta04-kernel
</pre>

==== Compile kernel ====

Prepare an environment to cross compile the kernel. First call another shell
instance for saving the current environment. This instance is not really
necessary but it is more convenient because the saved environment is restored
after exiting the new shell.

<pre>
bash
umask 0022
export ARCH=arm CROSS_COMPILE=${CROSSDEV_TARGET}-
export PS1="($ARCH) $PS1"
</pre>

The kernel does not support the blue symbols on the keys used by "Fn". To enable
this, patch the kernel using the patch file [[Cross Install Gentoo kernel-patch-Fn-keys.txt|kernel-patch-Fn-keys.txt]].

<pre>
patch -p1 <../kernel-patch-Fn-keys.txt
</pre>

This patches the files "arch/arm/boot/dts/omap3-pandora-common.dtsi" which will
get more key codes for the blue symbols and
"drivers/input/keyboard/twl4030_keypad.c" which will handle the keys.

Now a default configuration for the kernel will be created.

<pre>
make omap2plus_defconfig
</pre>

A lot of configuration must be done to make the kernel work. To ease this use
[[Cross Install Gentoo kernel-config|kernel-config]] which will configure a running
kernel for the Pandora. It uses the name "pherkad" as computer name. Change
this to any name you like in the config file. Calling oldconfig might be
necessary if "kernel-config" is too old for the current gta04-kernel.

<pre>
cp ../kernel-config .config
make oldconfig
make menuconfig
</pre>

In "General setup/Local version" change "-pherkad" to any name you like. But
use "-" as prefix.

Build the kernel and the device tree "omap3-pandora-600mhz.dtb". Pandora users
with 1 GHz units can use "omap3-pandora-1ghz.dts". Use as much CPU cores as you
have for the compiling process.

<pre>
export CPUS="$(grep processor /proc/cpuinfo | wc -l)"
make -j$CPUS zImage
make -j$CPUS modules
make omap3-pandora-600mhz.dtb
</pre>

Convert the kernel into an image for the U-Boot loader. Use any name you
like for "Linux-pherkad".

<pre>
mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008000 -n \
'Linux-pherkad' -d arch/arm/boot/zImage arch/arm/boot/uImage
</pre>

Generate a "boot.scr" file which loads the kernel image and the correct device
tree.

Keep an eye to the bootargs. It uses the following commands:

* Start the systemd as init process: "init=/lib/systemd/systemd".
* Be quiet: "quiet". This can be removed while development.
* Show a splash screen: "splash". There is currently no splash screen, so this
* Use the root file system at: "root=/dev/mmcblk0p2". Take care to use the same partition as described below.
* Use Ext 4 root file system: "rootfstype=ext4".
* Wait for root file system: "rootwait".
* Mount initially read only: "ro". systemd will remount it later as RW.
* Use the following SWAP partition for hibernation/resume: "resume=/dev/mmcblk0p3". This is currently not used.

The file "boot.txt" will be converted to the boot script "boot.src".

<pre>
cat >boot.txt <<EOF
if itest.w *0x4830a204 == 0x102f
then
setenv devicetree omap3-pandora-1ghz
else
setenv devicetree omap3-pandora-600mhz
fi
setenv defaultdisplay lcd
setenv bootargs "init=/lib/systemd/systemd quiet splash \
root=/dev/mmcblk0p2 rootfstype=ext4 rootwait ro resume=/dev/mmcblk0p3"
ext2load mmc 0:1 0x825f0000 /boot/\${devicetree}.dtb
ext2load mmc 0:1 0x80300000 /boot/uImage-pherkad
bootm 0x80300000 - 0x825f0000
EOF

mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n 'Boot script' \
-d boot.txt boot.scr
</pre>

Exit the kernel build environment.

<pre>
exit
</pre>

==== Install kernel ====

The installation of the kernel into the target directory must be done as root.
Create the "boot" directory for the kernel, device tree and boot script and
copy them to the target directory.

<pre>
su
umask 0022
cp arch/arm/boot/uImage /usr/$CROSSDEV_TARGET/boot/uImage-pherkad
cp .config /usr/$CROSSDEV_TARGET/boot/config-pherkad
cp System.map /usr/$CROSSDEV_TARGET/boot/System.map-pherkad
cp arch/arm/boot/dts/omap3-pandora-600mhz.dtb /usr/$CROSSDEV_TARGET/boot/.
cp boot.scr /usr/$CROSSDEV_TARGET/boot/.
</pre>

Create a link for the boot directory. This is used if the boot directory is an
own partition and the boot loader wants to load the kernel from "boot/uImage-*".
In our case it is not really necessary.

<pre>
(cd /usr/$CROSSDEV_TARGET/boot; ln -s . boot)
</pre>

Install all kernel modules into "target/lib/modules". The symbolic link is for
the cross compiling process to find the kernel configuration.

<pre>
make ARCH=arm CROSS_COMPILE=${CROSSDEV_TARGET}- \
INSTALL_MOD_PATH=/usr/$CROSSDEV_TARGET modules_install

(DIR="$PWD"; cd /usr/$CROSSDEV_TARGET/usr/src; ln -s $DIR linux)
cd ..
</pre>

=== Compile system ===

Now it's time to cross compile the whole Gentoo system. The base system is
already installed in the "target" directory. All the binaries there will
be compiled again with our own cross compiler. Also a lot of new packages
(more binaries) will be installed.

==== Prepare cross development system ====

Go to the target and copy all portage configurations from the desktop computer
to the target system, since we want to use the desktop computer system as
base of the Pandora system. This must be done as root.

<pre>
export FROM_DIR="$PWD"
cd /usr/$CROSSDEV_TARGET
</pre>

Edit the "make.conf" file.

<pre>
nano etc/portage/make.conf
</pre>

Change some of the lines there. You might copy some of the contents from
the desktop computer but be sure to have the same CHOST as the CROSSDEV_TARGET.
Especially add or change for the following:

<pre>
CFLAGS="-O2 -pipe -march=armv7-a -mfpu=vfpv3-d16 -mfloat-abi=softfp \
-mfpu=neon -fno-stack-protector"
</pre>

or

<pre>
CFLAGS="-O2 -pipe -march=armv7-a -mfpu=vfpv3-d16 -mfloat-abi=hard \
-mfpu=neon -fno-stack-protector"
</pre>

<pre>

--binpkg-respect-use=y"

GENTOO_MIRRORS="<enter your mirrors>"
PKGDIR="/usr/portage/packages/${CHOST}"
</pre>

It is recommended to activate the build of binary packages. The cross
compilation will fail to build some packages, so QEmu will build all packages
again. It is not necessary to build good cross compiled packages by QEmu again.
Using binary packages will avoid this and save a lot of time.

To avoid mixing up the binary packages of the desktop comuter and the Pandora
set PKGDIR accordingly. Example: "/usr/portage/packages/${CHOST}"

Also copy and edit some package specific files from your desktop computer.

<pre>
cp -r /etc/portage/package.* etc/portage/.
</pre>

Edit the files in "etc/portage/package.*" and configure the portage tree.

<pre>
sed -i "s/amd64/arm/g" etc/portage/package.keywords/*
rm -r etc/portage/package.keywords/cross*
rm -r etc/portage/package.mask/cross*
rm etc/portage/package.use/cross*
rm etc/portage/package.env/cross*

mkdir etc/portage/repos.conf
cp usr/share/portage/config/repos.conf etc/portage/repos.conf/gentoo.conf
rm -f etc/portage/make.profile

(cd etc/portage && \
ln -s /usr/portage/profiles/default/linux/arm/13.0/armv7a/desktop make.profile)
</pre>

Copy the world file from the desktop computer and remove all packages which
should not be installed on the Pandora system.

<pre>
cp /var/lib/portage/world var/lib/portage/world
nano var/lib/portage/world
</pre>

==== Prepare cross-compilation and QEmu environment ====

A lot of packages will fail but we will keep going the emerge process and
compile the failed packages again with QEmu.

But first update the compiler tools in the target system. They will be needed
later in the QEmu environment. If they fail here, try to do it in the QEmu
part.

Copy the static QEmu binary to the target system and set up portage for the
target system.

<pre>
cp /usr/bin/qemu-arm usr/bin/.
mkdir -p usr/portage
touch usr/portage/.keep
</pre>

Do some standard setup for the target system. Copy some personal configurations
to the root account.

<pre>
cp -L /etc/resolv.conf etc/.
cp -r etc/skel/. root/.

cp /root/.bashrc /root/.dir_colors /root/.screenrc /root/.toprc \
/root/.xsession root/.
</pre>

Some nice tools like htop are worth to install them on the Pandora.

<pre>
mkdir -m0700 root/.config
cp -r /root/.config/htop root/.config/.
</pre>

To access the root account with ssh, copy its configuration. This copies the
"id_*" files, also. Don't do this if you deliberately take care about security.

<pre>
cp -r /root/.ssh/. root/.ssh/.
</pre>

==== Start cross compilation ====

Set up a cross compilation environment (use a third shell instance).

<pre>
bash
export CBUILD=x86_64-pc-linux-gnu
export CHOST=$CROSSDEV_TARGET
export ROOT=$PWD
export PORTAGE_CONFIGROOT=$ROOT
export PS1="($CHOST) $PS1"
</pre>

Try to cross compile all packages.

<pre>
$CHOST-emerge -a binutils glibc linux-headers gcc
$CHOST-emerge -a linux-firmware
$CHOST-emerge -ae @world
</pre>

If one of them fails, save the resume list.

<pre>
$CHOST-emerge -p --resume | grep "^\[[eb].*\]" | grep -ve "^\[blocks" | \
cut -b 18- | cut -d " " -f1 | awk '{ print("=" $0); }' >tmp/packages.txt
</pre>

Now go to "Continue cross-compilation with QEmu".

==== Continue cross-compilation with QEmu ====

Enter the chroot environment and emerge the failed package again (the first one
in the packages.txt file).

The portage tree will be mounted into the target system.

In the chroot environment it might be necessary to switch the compiler. Check
if the same version of gcc is used than the cross compiler with
"gcc-config -l". Set the correct version before starting "emerge".

<pre>
mkdir -p $PWD/run/systemd/resolve
cp /run/systemd/resolve/resolv.conf $PWD/run/systemd/resolve/.
mount --rbind /proc $PWD/proc
mount --make-rslave $PWD/proc
mount --rbind /sys $PWD/sys
mount --make-rslave $PWD/sys
mount --rbind /dev $PWD/dev
mount --make-rslave $PWD/dev
mount --rbind /usr/portage $PWD/usr/portage
chroot $PWD /bin/bash
unset CBUILD CHOST ROOT PORTAGE_CONFIGROOT
env-update
source /etc/profile
cd
source ./.bashrc
export PS1="(chroot) $PS1"
emerge -aB1 $(head -1 /tmp/packages.txt)
exit
umount -l usr/portage
umount -l dev sys proc
</pre>

After fixing the failed package(s), continue with the cross compiler.

<pre>
cat tmp/packages.txt | xargs $CHOST-emerge -1
</pre>

=== Fix lib64-problem ===

Some cross compiled packages install their libraries into the "lib64" directory.
This is not used on the Pandora. So we have to copy all contents from "lib64"
to "lib" and set a link for "lib64".

<pre>
rsync -avc usr/lib64/. usr/lib/.
rm -rf usr/lib64
(cd usr && ln -s lib lib64)
</pre>

=== Configure system ===

Set the key map for Pandora in the console and, as usual in Gentoo,
configure the target system.

Use to make the Pandora keyboard work on the console.
([[Cross Install Gentoo Keymap-pandora.map|keymap-pandora.map]])

<pre>
cp "$FROM_DIR/keymap-pandora.map" etc/.
chmod 644 etc/keymap-pandora.map
echo >etc/vconsole.conf "KEYMAP=/etc/keymap-pandora.map"
echo >>etc/vconsole.conf "FONT=eurlatgr"
</pre>

Set up the mount table. Every line in "etc/fstab" will be commented out and
new entries added. The file system labels are used to mount the partitions.

<pre>

= Create SD-card partitions phlnx_boot/root/swap/home =

Finally the target system is done. Now it's time to copy it to the Pandora.

== Pandora ==

It's recommended to partition the SD-card for the target system on the Pandora.
Otherwise the boot loader might refuse to work.

Insert the SD-card in the left slot (mmcblk0) and unmount it if necessary.

Create the following partitions:

* A boot partition (ext2).
* A root partition which will contain the target system (at least 4 GB).
* A home partition which we can use later.
* A SWAP partition which we can use later.

<pre>
sudo -s

/sbin/fdisk /dev/mmcblk0
Create new DOS partition label: o
Create new partition: n p 1 Return +8M
Create new partition: n p 2 Return +4G
Create new partition: n p 3 Return +1G
Change partition type: t 3 82 (Linux swap)
Create new partition: n p Return Return
Write all changes: w

/sbin/mkfs.ext2 -FL phlnx_boot /dev/mmcblk0p1
/sbin/mkfs.ext4 -FL phlnx_root -O ^has_journal /dev/mmcblk0p2
/sbin/mkswap -L phlnx_swap /dev/mmcblk0p3
/sbin/mkfs.ext4 -FL phlnx_home -O ^has_journal /dev/mmcblk0p4
exit
</pre>

= Option #1: Copy target system to SD-card =

One of the possibilities to copy the target system to the SD-card on the Pandora
is to use a USB cable connecting the Pandora to the desktop computer.

It's also possible to copy it via the WiFi network (see below).

== Pandora ==

Connect the Pandora via USB to the desktop computer. Insert the SD-card in the
left slot (mmcblk0). Use menu "System/SD-Mass Storage" to access partition
"phlnx_root".

== Desktop computer ==

Mount the root partition and copy the target system. Use the correct "/dev/sd*".

<pre>
su
mkdir /tmp/mnt
mount /dev/sdc /tmp/mnt
mkdir -p /tmp/mnt/boot
touch /tmp/mnt/boot/.keep
mkdir -p /tmp/mnt/home
touch /tmp/mnt/home/.keep

rsync -av --delete --exclude lost+found --exclude /boot \
CrossDev/$CROSSDEV_TARGET/. /tmp/mnt/.

umount /tmp/mnt
</pre>

== Pandora ==

Use "System/SD-Mass Storage" again to access phlnx_boot.

== Desktop computer ==

Mount the boot partition and copy boot directory of the target system.

<pre>
mount /dev/sdc /tmp/mnt
rm -f /tmp/mnt/uImage-pherkad

rsync -av --delete --exclude lost+found \
CrossDev/$CROSSDEV_TARGET/boot/. /tmp/mnt/.

umount /tmp/mnt
rmdir /tmp/mnt
exit
</pre>

== Pandora ==

End SD-Mass Storage.

= Option #2: Copy target system to SD-card via WiFi network =

== Pandora ==

Copy all files from the desktop computer to the SD-card partitions. Use the
same CROSSDEV_TARGET and FROM_DIR environment settings as on the desktop
computer.

<pre>
sudo -s
export REMOTE=mizar.spdns.de
export FROM_DIR=/home/jgeiss/Data/Systems/Pandora/Pherkad/Linux/Gentoo/CrossDev
export CROSSDEV_TARGET=armv7a-hardfloat-linux-gnueabi

mkdir -p /media/phlnx_root/boot
touch /media/phlnx_root/boot/.keep

rsync -av --numeric-ids --delete --exclude lost+found --exclude /boot \
$REMOTE:$FROM_DIR/$CROSSDEV_TARGET/. /media/phlnx_root/.

rsync -av --delete --exclude lost+found \
$REMOTE:$FROM_DIR/$CROSSDEV_TARGET/boot/. /media/phlnx_boot/.

exit
</pre>

= Boot the new system =

Reboot the Pandora and hold the right shoulder button until the boot menu
appears.

'''Sometimes it is necessary to switch off the Pandora for 10-60 seconds.'''

Choose "boot from SD1:1".

It the boot works well, login as root and play around.

== Optional: USB-networking ==

To use networking to the desktop computer via USB cable, execute the
following commands on both systems.

=== Pandora ===

<pre>
modprobe g_ether
ifconfig usb0 192.168.129.3 netmask 255.255.255.0
route add default gw 192.168.129.2
systemctl start sshd
</pre>

=== Desktop computer ===

Configure the corresponding network interface.

<pre>
ifconfig enp0s20u1u1 192.168.129.2 netmask 255.255.255.0
</pre>

Now you should be able to connect to the Pandora.

<pre>
ssh root@192.168.129.3
</pre>

== Shutdown Pandora ==

To shutdown the Pandora system enter the following command.

<pre>
systemctl poweroff
</pre>

= Open issues =

The following things are currently not working and need to be implemented/fixed:

* wl1251 board initialization failed
* tw1: not initialized
* omapfb omapfb: no displays, failed to setup omapfb
* omap2_set_init_voltage: unable to find boot up OPP vor ...
* __nand_correct_data: uncorrectable ECC error
* Buffer I/O error on dev mtdblock0, logical block 0, async page read
* Cursor and other GPIO-related keys do not work correctly if CPU is idle. Workaround: echo 1 >/sys/devices/system/cpu/cpu0/cpuidle/state4/disable
* Kernel panic at system shutdown
* fstab: Auto-Mounting /boot or /home causes system suspend after about 30 Seconds.

Cross Install Gentoo

2018-06-06T10:19:17Z

Jgeiss: Table of contents corrected

= Cross install Gentoo Linux on Pandora =

== Introduction ==

These instructions are for installing a recent Gentoo Linux on the OpenPandora
handheld console. The system will be installed and booted from a SD-card. The
Gentoo Linux will be cross-compiled on another desktop computer also running
Gentoo Linux.

It is not necessary to follow all instructions exactly. Some of them can be
changed to your own needs.

'''The system currently supports only the text console and no X11 or sound.'''
'''Also a lot of features are missing.''' See "Open issues" at the end.

=== Prerequisites ===

These instructions assume the following prerequisites:

* Good knowledge in Gentoo Linux.
* A desktop computer running Gentoo Linux. Other Linux is, of course, also possible but requires proper adaption of these instructions.
* An OpenPandora handheld console.
* A SD-card with least 8 GB size.
* A USB cable to connect the Pandora to the desktop computer.

=== Improvement ===

Due to the constant changes of the Linux kernel, GNU software, etc. this
document will be outdated very quick. To avoid this, help is always appreciated
improving this document. If you can update, improve, add or complete this
document, don't hesitate to do so.

== Prepare/install cross compile system ==

To perform the cross-compilation a cross compiler and QEmu must be installed
on the desktop computer. QEmu will help a lot for compiling packages which
will not properly cross compile.

=== Install cross compiling system ===

For compiling software for an ARM controller a cross compiler must be installed.

We can use ARMv7 using either soft float (armv7a-softfp-linux-gnueabi) or hard
float (armv7a-hardfloat-linux-gnueabi).

<pre>export CROSSDEV_TARGET=armv7a-softfp-linux-gnueabi</pre>

or

<pre>export CROSSDEV_TARGET=armv7a-hardfloat-linux-gnueabi</pre>

The additional portage tree in "/usr/local/portage-crossdev" will hold all
information for emerging the cross build system (cross compiler and tools).

To prepare emerging a cross compiler, execute the following commands.

<pre>
su
umask 0022

emerge -av crossdev

mkdir -p /usr/local/portage-crossdev/{profiles,metadata}

echo 'local-crossdev' >/usr/local/portage-crossdev/profiles/repo_name
echo 'masters = gentoo' >/usr/local/portage-crossdev/metadata/layout.conf
echo 'thin-manifests = true' >>/usr/local/portage-crossdev/metadata/layout.conf
chown -R portage:portage /usr/local/portage-crossdev

echo '[local-crossdev]' >/etc/portage/repos.conf/crossdev.conf

echo 'location = /usr/local/portage-crossdev' \
>>/etc/portage/repos.conf/crossdev.conf

echo 'priority = 10' >>/etc/portage/repos.conf/crossdev.conf
echo 'masters = gentoo' >>/etc/portage/repos.conf/crossdev.conf
echo 'auto-sync = no' >>/etc/portage/repos.conf/crossdev.conf
</pre>

The portage tree for emerging the cross build system is set up. Now we have to
find out which versions of the cross build components are about to be installed.
The target system will get binutils, gcc, glibc and linux-headers of a certain
version. The same version should be installed in the cross build system.

<pre>
export BINUTILS_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-devel/binutils/binutils-*.ebuild | tail -1 | \
awk 'match($0, ".*/binutils-(.*).ebuild", v) { print(v[1]); }')

export GCC_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-devel/gcc/gcc-*.ebuild | tail -1 | \
awk 'match($0, ".*/gcc-(.*).ebuild", v) { print(v[1]); }')

export GLIBC_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-libs/glibc/glibc-*.ebuild | tail -1 | \
awk 'match($0, ".*/glibc-(.*).ebuild", v) { print(v[1]); }')

export LINUX_HEADERS_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-kernel/linux-headers/linux-headers-*.ebuild | tail -1 | \
awk 'match($0, ".*/linux-headers-(.*).ebuild", v) { print(v[1]); }')
</pre>

Now emerge the cross compiler.

<pre>
crossdev --binutils $BINUTILS_VER --gcc $GCC_VER --libc $GLIBC_VER \
--kernel $LINUX_HEADERS_VER --target $CROSSDEV_TARGET
</pre>

=== Install QEmu ===

A lot of packages will not cross compile properly. QEmu will help for these
packages. Install it to emulate an ARM controller.

Edit /etc/portage/make.conf.

<pre>
nano /etc/portage/make.conf
</pre>

And add the following lines.

<pre>
QEMU_SOFTMMU_TARGETS=""
QEMU_USER_TARGETS="arm"
</pre>

Also enable the use flag static-user. This builds QEmu as static binary.
QEmu will be used later in a chroot environment of an ARM controller and will
be unable to access needed shared libraries. So it must contain all these
libraries by building it in a static way.

<pre>
euse -E static-user
</pre>

All the needed libraries for QEmu must also be available as library archive
(static libs). Emerging QEmu will request to emerge these libraries as
static variants, also. Create and add these libraries in the file
"/etc/portage/package.use/qemu". Look which libraries are needed.

<pre>
emerge -pv qemu
</pre>

And add them with the use flag static-libs. Here is an Example:

<pre>
>=net-misc/curl-7.53.0 static-libs
>=sys-apps/attr-2.4.47-r2 static-libs
>=media-libs/libsdl-1.2.15-r9 static-libs
>=sys-apps/dtc-1.4.1 static-libs
>=app-arch/bzip2-1.0.6-r7 static-libs
>=x11-libs/pixman-0.34.0 static-libs
>=dev-libs/libpcre-8.40-r1 static-libs
>=sys-libs/libseccomp-2.3.0 static-libs
>=net-fs/libnfs-1.9.7 static-libs
>=dev-libs/cyrus-sasl-2.1.26-r9 static-libs
>=dev-libs/gmp-6.1.0 static-libs
>=dev-libs/libaio-0.3.110 static-libs
>=sys-fs/xfsprogs-4.5.0 static-libs
>=sys-libs/zlib-1.2.11 static-libs
>=media-libs/libjpeg-turbo-1.5.0 static-libs
>=sys-libs/libcap-ng-0.7.8 static-libs
>=dev-libs/openssl-1.0.2k static-libs
>=dev-libs/glib-2.50.3-r1 static-libs
>=virtual/jpeg-0-r2:0 static-libs
>=media-libs/libpng-1.6.27 static-libs
>=sys-libs/ncurses-6.0-r1 static-libs
</pre>

Emerge QEmu.

<pre>
emerge qemu
udevadm trigger -c add /dev/kvm
</pre>

QEmu will execute ARM binaries on the desktop computer as if it would have an
ARM controller. To achieve this, register foreign binaries and start the
systemd service.

<pre>
ln -s /usr/share/qemu/binfmt.d/qemu.conf /etc/binfmt.d/qemu.conf
systemctl start systemd-binfmt
</pre>

Now our desktop computer is able to execute ARM binaries as well as his own
binaries.

=== Install GIT ===

To get the kernel sources, GIT will be needed. Emerge it.

<pre>
emerge git
</pre>

Exit the root shell.

<pre>
exit
</pre>

Now the cross build system is ready to compile a Gentoo Linux for the Pandora.

== Install system ==

=== Prepare target file system ===

To build the system for the Pandora about 10 GB disk space is needed. Create a
directory "CrossDev" to store all data there.

<pre>
mkdir CrossDev
cd CrossDev
</pre>

In this directory two more directories will be created:

* One to store and build the Linux kernel.
* Another will store the whole system for the Pandora including QEmu which is not really a part of the system for Pandora, but it is needed as long as the building process runs.
* Some files and archives.

First get the Gentoo base system "stage3-armv7a-*.tar.bz2". Download it from
a suitable mirror of the Gentoo distribution. See
https://www.gentoo.org/downloads/mirrors for a list of mirrors.

Go to the directory "releases/arm/autobuilds". According to your target, enter

* "current-stage3-armv7a" for soft float (armv7a-softfp-linux-gnueabi),
* "current-stage3-armv7a_hardfp" for hard float (armv7a-hardfloat-linux-gnueabi).

There is a stage 3 file for ARMv7. Download this archive.

Example:

<pre>
wget http://mirror.eu.oneandone.net/linux/distributions/gentoo/gentoo/\
releases/arm/autobuilds/current-stage3-armv7a/stage3-armv7a-20161129.tar.bz2
</pre>

or

<pre>
wget http://mirror.eu.oneandone.net/linux/distributions/gentoo/gentoo/\
releases/arm/autobuilds/current-stage3-armv7a_hardfp/\
stage3-armv7a_hardfp-20161129.tar.bz2
</pre>

As long as we are cross compiling, we use "/usr/$CROSSDEV_TARGET" as working
directory. The cross compiler looks for libraries there and uses many references
to this directory. That's why "/usr/$CROSSDEV_TARGET" will be saved, so it can
be restored after the build.

<pre>
su
umask 0022
tar -cpjf ${CROSSDEV_TARGET}-saved.tar.bz2 -C /usr $CROSSDEV_TARGET
</pre>

Unpack the stage 3 archive into "/usr/$CROSSDEV_TARGET".

<pre>
tar --xattrs --numeric-owner -xpjf stage3-*.tar.bz2 -C /usr/$CROSSDEV_TARGET
</pre>

Sometimes there is a lot of garbage in the "tmp" directory. Remove it.

<pre>
rm -rf /usr/$CROSSDEV_TARGET/tmp/*
</pre>

Exit the root shell and go back to our working directory.

<pre>
exit
</pre>

=== Compile/install kernel ===

The standard Gentoo kernel will not run on the Pandora (or, at least, takes too
much effort to make it run), so download a current kernel from
https://goldelico.com using GIT.

==== Download kernel ====

Download the kernel with GIT.

<pre>
git clone git://git.goldelico.com/gta04-kernel.git
cd gta04-kernel
</pre>

==== Compile kernel ====

Prepare an environment to cross compile the kernel. First call another shell
instance for saving the current environment. This instance is not really
necessary but it is more convenient because the saved environment is restored
after exiting the new shell.

<pre>
bash
umask 0022
export ARCH=arm CROSS_COMPILE=${CROSSDEV_TARGET}-
export PS1="($ARCH) $PS1"
</pre>

The kernel does not support the blue symbols on the keys used by "Fn". To enable
this, patch the kernel using the patch file [[Cross Install Gentoo kernel-patch-Fn-keys.txt|kernel-patch-Fn-keys.txt]].

<pre>
patch -p1 <../kernel-patch-Fn-keys.txt
</pre>

This patches the files "arch/arm/boot/dts/omap3-pandora-common.dtsi" which will
get more key codes for the blue symbols and
"drivers/input/keyboard/twl4030_keypad.c" which will handle the keys.

Now a default configuration for the kernel will be created.

<pre>
make omap2plus_defconfig
</pre>

A lot of configuration must be done to make the kernel work. To ease this use
[[Cross Install Gentoo kernel-config|kernel-config]] which will configure a running
kernel for the Pandora. It uses the name "pherkad" as computer name. Change
this to any name you like in the config file. Calling oldconfig might be
necessary if "kernel-config" is too old for the current gta04-kernel.

<pre>
cp ../kernel-config .config
make oldconfig
make menuconfig
</pre>

In "General setup/Local version" change "-pherkad" to any name you like. But
use "-" as prefix.

Build the kernel and the device tree "omap3-pandora-600mhz.dtb". Pandora users
with 1 GHz units can use "omap3-pandora-1ghz.dts". Use as much CPU cores as you
have for the compiling process.

<pre>
export CPUS="$(grep processor /proc/cpuinfo | wc -l)"
make -j$CPUS zImage
make -j$CPUS modules
make omap3-pandora-600mhz.dtb
</pre>

Convert the kernel into an image for the U-Boot loader. Use any name you
like for "Linux-pherkad".

<pre>
mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008000 -n \
'Linux-pherkad' -d arch/arm/boot/zImage arch/arm/boot/uImage
</pre>

Generate a "boot.scr" file which loads the kernel image and the correct device
tree.

Keep an eye to the bootargs. It uses the following commands:

* Start the systemd as init process: "init=/lib/systemd/systemd".
* Be quiet: "quiet". This can be removed while development.
* Show a splash screen: "splash". There is currently no splash screen, so this
* Use the root file system at: "root=/dev/mmcblk0p2". Take care to use the same partition as described below.
* Use Ext 4 root file system: "rootfstype=ext4".
* Wait for root file system: "rootwait".
* Mount initially read only: "ro". systemd will remount it later as RW.
* Use the following SWAP partition for hibernation/resume: "resume=/dev/mmcblk0p3". This is currently not used.

The file "boot.txt" will be converted to the boot script "boot.src".

<pre>
cat >boot.txt <<EOF
if itest.w *0x4830a204 == 0x102f
then
setenv devicetree omap3-pandora-1ghz
else
setenv devicetree omap3-pandora-600mhz
fi
setenv defaultdisplay lcd
setenv bootargs "init=/lib/systemd/systemd quiet splash \
root=/dev/mmcblk0p2 rootfstype=ext4 rootwait ro resume=/dev/mmcblk0p3"
ext2load mmc 0:1 0x825f0000 /boot/\${devicetree}.dtb
ext2load mmc 0:1 0x80300000 /boot/uImage-pherkad
bootm 0x80300000 - 0x825f0000
EOF

mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n 'Boot script' \
-d boot.txt boot.scr
</pre>

Exit the kernel build environment.

<pre>
exit
</pre>

==== Install kernel ====

The installation of the kernel into the target directory must be done as root.
Create the "boot" directory for the kernel, device tree and boot script and
copy them to the target directory.

<pre>
su
umask 0022
cp arch/arm/boot/uImage /usr/$CROSSDEV_TARGET/boot/uImage-pherkad
cp .config /usr/$CROSSDEV_TARGET/boot/config-pherkad
cp System.map /usr/$CROSSDEV_TARGET/boot/System.map-pherkad
cp arch/arm/boot/dts/omap3-pandora-600mhz.dtb /usr/$CROSSDEV_TARGET/boot/.
cp boot.scr /usr/$CROSSDEV_TARGET/boot/.
</pre>

Create a link for the boot directory. This is used if the boot directory is an
own partition and the boot loader wants to load the kernel from "boot/uImage-*".
In our case it is not really necessary.

<pre>
(cd /usr/$CROSSDEV_TARGET/boot; ln -s . boot)
</pre>

Install all kernel modules into "target/lib/modules". The symbolic link is for
the cross compiling process to find the kernel configuration.

<pre>
make ARCH=arm CROSS_COMPILE=${CROSSDEV_TARGET}- \
INSTALL_MOD_PATH=/usr/$CROSSDEV_TARGET modules_install

(DIR="$PWD"; cd /usr/$CROSSDEV_TARGET/usr/src; ln -s $DIR linux)
cd ..
</pre>

=== Compile system ===

Now it's time to cross compile the whole Gentoo system. The base system is
already installed in the "target" directory. All the binaries there will
be compiled again with our own cross compiler. Also a lot of new packages
(more binaries) will be installed.

==== Prepare cross development system ====

Go to the target and copy all portage configurations from the desktop computer
to the target system, since we want to use the desktop computer system as
base of the Pandora system. This must be done as root.

<pre>
export FROM_DIR="$PWD"
cd /usr/$CROSSDEV_TARGET
</pre>

Edit the "make.conf" file.

<pre>
nano etc/portage/make.conf
</pre>

Change some of the lines there. You might copy some of the contents from
the desktop computer but be sure to have the same CHOST as the CROSSDEV_TARGET.
Especially add or change for the following:

<pre>
CFLAGS="-O2 -pipe -march=armv7-a -mfpu=vfpv3-d16 -mfloat-abi=softfp \
-mfpu=neon -fno-stack-protector"
</pre>

or

<pre>
CFLAGS="-O2 -pipe -march=armv7-a -mfpu=vfpv3-d16 -mfloat-abi=hard \
-mfpu=neon -fno-stack-protector"
</pre>

<pre>

--binpkg-respect-use=y"

GENTOO_MIRRORS="<enter your mirrors>"
PKGDIR="/usr/portage/packages/${CHOST}"
</pre>

It is recommended to activate the build of binary packages. The cross
compilation will fail to build some packages, so QEmu will build all packages
again. It is not necessary to build good cross compiled packages by QEmu again.
Using binary packages will avoid this and save a lot of time.

To avoid mixing up the binary packages of the desktop comuter and the Pandora
set PKGDIR accordingly. Example: "/usr/portage/packages/${CHOST}"

Also copy and edit some package specific files from your desktop computer.

<pre>
cp -r /etc/portage/package.* etc/portage/.
</pre>

Edit the files in "etc/portage/package.*" and configure the portage tree.

<pre>
sed -i "s/amd64/arm/g" etc/portage/package.keywords/*
rm -r etc/portage/package.keywords/cross*
rm -r etc/portage/package.mask/cross*
rm etc/portage/package.use/cross*
rm etc/portage/package.env/cross*

mkdir etc/portage/repos.conf
cp usr/share/portage/config/repos.conf etc/portage/repos.conf/gentoo.conf
rm -f etc/portage/make.profile

(cd etc/portage && \
ln -s /usr/portage/profiles/default/linux/arm/13.0/armv7a/desktop make.profile)
</pre>

Copy the world file from the desktop computer and remove all packages which
should not be installed on the Pandora system.

<pre>
cp /var/lib/portage/world var/lib/portage/world
nano var/lib/portage/world
</pre>

==== Prepare cross-compilation and QEmu environment ====

A lot of packages will fail but we will keep going the emerge process and
compile the failed packages again with QEmu.

But first update the compiler tools in the target system. They will be needed
later in the QEmu environment. If they fail here, try to do it in the QEmu
part.

Copy the static QEmu binary to the target system and set up portage for the
target system.

<pre>
cp /usr/bin/qemu-arm usr/bin/.
mkdir -p usr/portage
touch usr/portage/.keep
</pre>

Do some standard setup for the target system. Copy some personal configurations
to the root account.

<pre>
cp -L /etc/resolv.conf etc/.
cp -r etc/skel/. root/.

cp /root/.bashrc /root/.dir_colors /root/.screenrc /root/.toprc \
/root/.xsession root/.
</pre>

Some nice tools like htop are worth to install them on the Pandora.

<pre>
mkdir -m0700 root/.config
cp -r /root/.config/htop root/.config/.
</pre>

To access the root account with ssh, copy its configuration. This copies the
"id_*" files, also. Don't do this if you deliberately take care about security.

<pre>
cp -r /root/.ssh/. root/.ssh/.
</pre>

==== Start cross compilation ====

Set up a cross compilation environment (use a third shell instance).

<pre>
bash
export CBUILD=x86_64-pc-linux-gnu
export CHOST=$CROSSDEV_TARGET
export ROOT=$PWD
export PORTAGE_CONFIGROOT=$ROOT
export PS1="($CHOST) $PS1"
</pre>

Try to cross compile all packages.

<pre>
$CHOST-emerge -a binutils glibc linux-headers gcc
$CHOST-emerge -ae @world
</pre>

If one of them fails, save the resume list.

<pre>
$CHOST-emerge -p --resume | grep "^\[[eb].*\]" | grep -ve "^\[blocks" | \
cut -b 18- | cut -d " " -f1 | awk '{ print("=" $0); }' >tmp/packages.txt
</pre>

Now go to "Continue cross-compilation with QEmu".

==== Continue cross-compilation with QEmu ====

Enter the chroot environment and emerge the failed package again (the first one
in the packages.txt file).

The portage tree will be mounted into the target system.

In the chroot environment it might be necessary to switch the compiler. Check
if the same version of gcc is used than the cross compiler with
"gcc-config -l". Set the correct version before starting "emerge".

<pre>
mkdir -p $PWD/run/systemd/resolve
cp /run/systemd/resolve/resolv.conf $PWD/run/systemd/resolve/.
mount --rbind /proc $PWD/proc
mount --make-rslave $PWD/proc
mount --rbind /sys $PWD/sys
mount --make-rslave $PWD/sys
mount --rbind /dev $PWD/dev
mount --make-rslave $PWD/dev
mount --rbind /usr/portage $PWD/usr/portage
chroot $PWD /bin/bash
unset CBUILD CHOST ROOT PORTAGE_CONFIGROOT
env-update
source /etc/profile
cd
source ./.bashrc
export PS1="(chroot) $PS1"
emerge -aB1 $(head -1 /tmp/packages.txt)
exit
umount -l usr/portage
umount -l dev sys proc
</pre>

After fixing the failed package(s), continue with the cross compiler.

<pre>
cat tmp/packages.txt | xargs $CHOST-emerge -1
</pre>

If one of them fails again, save the resume list.

<pre>
$CHOST-emerge -p --resume | grep "^\[[eb].*\]" | grep -ve "^\[blocks" | \
cut -b 18- | cut -d " " -f1 | awk '{ print("=" $0); }' >tmp/packages.txt
</pre>

*Go back to "Continue cross-compilation with QEmu" until all packages are merged
successfully.*

Remove some leftover temporary files.

<pre>
rm -rf /var/tmp/portage/* /usr/$CROSSDEV_TARGET/var/tmp/portage/* \
/usr/$CROSSDEV_TARGET/tmp/packages.txt
</pre>

=== Fix lib64-problem ===

Some cross compiled packages install their libraries into the "lib64" directory.
This is not used on the Pandora. So we have to copy all contents from "lib64"
to "lib" and set a link for "lib64".

<pre>
rsync -avc usr/lib64/. usr/lib/.
rm -rf usr/lib64
(cd usr && ln -s lib lib64)
</pre>

=== Configure system ===

Set the key map for Pandora in the console and, as usual in Gentoo,
configure the target system.

Use to make the Pandora keyboard work on the console.
([[Cross Install Gentoo Keymap-pandora.map|keymap-pandora.map]])

<pre>
cp "$FROM_DIR/keymap-pandora.map" etc/.
chmod 644 etc/keymap-pandora.map
echo >etc/vconsole.conf "KEYMAP=/etc/keymap-pandora.map"
echo >>etc/vconsole.conf "FONT=eurlatgr"
</pre>

Set up the mount table. Every line in "etc/fstab" will be commented out and
new entries added. The file system labels are used to mount the partitions.

<pre>
sed -ie "s,^/,#/,g" etc/fstab

cat >>etc/fstab <<EOF
LABEL=phlnx_boot /boot ext2 noauto,noatime 1 2
LABEL=phlnx_root / ext4 errors=remount-ro,noatime 1 1
LABEL=phlnx_home /home ext4 noauto,noatime,nodev,nosuid 1 2
EOF
</pre>

Enter the chroot environment again.

<pre>
mount --rbind /proc $PWD/proc
mount --make-rslave $PWD/proc
mount --rbind /sys $PWD/sys
mount --make-rslave $PWD/sys
mount --rbind /dev $PWD/dev
mount --make-rslave $PWD/dev
mount --rbind /usr/portage $PWD/usr/portage
chroot $PWD /bin/bash
unset CBUILD CHOST ROOT PORTAGE_CONFIGROOT
env-update
source /etc/profile
cd
source ./.bashrc
export PS1="(chroot) $PS1"
</pre>

Set a password for root.

<pre>
passwd
</pre>

Update the configuration files and read/clear all news from portage.

<pre>
dispatch-conf
eselect news list
eselect news read
eselect news purge
</pre>

Enter the time zone and generate the locale info you want (example: enable all
lines with en_US and de_DE).

<pre>
echo "Europe/Berlin" >/etc/timezone
emerge --config sys-libs/timezone-data
nano -w /etc/locale.gen
locale-gen
</pre>

Use en_US.utf8 (entry #9) as locale.

<pre>
eselect locale list
eselect locale set 9
</pre>

Set up mount table, the machine ID and host name.

<pre>
ln -sf /proc/self/mounts /etc/mtab
systemd-machine-id-setup
echo >/etc/machine-info "PRETTY_HOSTNAME=Pherkad"
echo >/etc/hostname "pherkad"
ln -snf /run/systemd/resolve/resolv.conf /etc/resolv.conf
systemctl enable systemd-resolved.service
</pre>

Exit the chroot environment.

<pre>
exit
umount -l usr/portage
umount -l dev sys proc
</pre>

Remove the QEmu binary. It is not used anymore.

<pre>
rm usr/bin/qemu-arm
</pre>

Also remove some leftovers from the cross compiler and the link to our kernel
sources.

<pre>
rm -f etc/portage/profile/package.provided
rm -f sys-include
rm -f usr/src/linux
</pre>

Copy back the target system and restore the previous cross compiler state.

<pre>
cd "$FROM_DIR"
mkdir $CROSSDEV_TARGET
rsync -a /usr/$CROSSDEV_TARGET/. $CROSSDEV_TARGET/.
rm -rf /usr/$CROSSDEV_TARGET
tar -xpjf ${CROSSDEV_TARGET}-saved.tar.bz2 -C /usr
rm ${CROSSDEV_TARGET}-saved.tar.bz2
</pre>

Exit the root shell.

<pre>
exit
</pre>

= Update system =

To update the system, use a similar approach as in the cross compilation phase.
Define CROSSDEV_TARGET as in "Install cross compiling system".

== Start cross-compilation ==

Set up a cross compilation environment (become root and use a second shell
instance again).

<pre>
cd CrossDev

= Create SD-card partitions phlnx_boot/root/swap/home =

Finally the target system is done. Now it's time to copy it to the Pandora.

== Pandora ==

It's recommended to partition the SD-card for the target system on the Pandora.
Otherwise the boot loader might refuse to work.

Insert the SD-card in the left slot (mmcblk0) and unmount it if necessary.

Create the following partitions:

* A boot partition (ext2).
* A root partition which will contain the target system (at least 4 GB).
* A home partition which we can use later.
* A SWAP partition which we can use later.

<pre>
sudo -s

/sbin/fdisk /dev/mmcblk0
Create new DOS partition label: o
Create new partition: n p 1 Return +8M
Create new partition: n p 2 Return +4G
Create new partition: n p 3 Return +1G
Change partition type: t 3 82 (Linux swap)
Create new partition: n p Return Return
Write all changes: w

/sbin/mkfs.ext4 -FL phlnx_home -O ^has_journal /dev/mmcblk0p4
exit
</pre>

= Option #1: Copy target system to SD-card =

One of the possibilities to copy the target system to the SD-card on the Pandora
is to use a USB cable connecting the Pandora to the desktop computer.

It's also possible to copy it via the WiFi network (see below).

== Pandora ==

Connect the Pandora via USB to the desktop computer. Insert the SD-card in the
left slot (mmcblk0). Use menu "System/SD-Mass Storage" to access partition
"phlnx_root".

== Desktop computer ==

Mount the root partition and copy the target system. Use the correct "/dev/sd*".

<pre>

</pre>

= Boot the new system =

Reboot the Pandora and hold the right shoulder button until the boot menu
appears.

'''Sometimes it is necessary to switch off the Pandora for 10-60 seconds.'''

Choose "boot from SD1:1".

It the boot works well, login as root and play around.

== Optional: USB-networking ==

To use networking to the desktop computer via USB cable, execute the
following commands on both systems.

=== Pandora ===

<pre>
modprobe g_ether
ifconfig usb0 192.168.129.3 netmask 255.255.255.0
route add default gw 192.168.129.2
systemctl start sshd
</pre>

=== Desktop computer ===

Configure the corresponding network interface.

<pre>
ifconfig enp0s20u1u1 192.168.129.2 netmask 255.255.255.0
</pre>

Now you should be able to connect to the Pandora.

<pre>
ssh root@192.168.129.3
</pre>

== Shutdown Pandora ==

To shutdown the Pandora system enter the following command.

<pre>
systemctl poweroff
</pre>

= Open issues =

The following things are currently not working and need to be implemented/fixed:

* wl1251 board initialization failed
* tw1: not initialized
* omapfb omapfb: no displays, failed to setup omapfb
* omap2_set_init_voltage: unable to find boot up OPP vor ...

Cross Install Gentoo

2018-06-05T06:53:00Z

Jgeiss: Link fixed

= Cross install Gentoo Linux on Pandora =

== Introduction ==

These instructions are for installing a recent Gentoo Linux on the OpenPandora
handheld console. The system will be installed and booted from a SD-card. The
Gentoo Linux will be cross-compiled on another desktop computer also running
Gentoo Linux.

It is not necessary to follow all instructions exactly. Some of them can be
changed to your own needs.

'''The system currently supports only the text console and no X11 or sound.'''
'''Also a lot of features are missing.''' See "Open issues" at the end.

=== Prerequisites ===

These instructions assume the following prerequisites:

* Good knowledge in Gentoo Linux.
* A desktop computer running Gentoo Linux. Other Linux is, of course, also possible but requires proper adaption of these instructions.
* An OpenPandora handheld console.
* A SD-card with least 8 GB size.
* A USB cable to connect the Pandora to the desktop computer.

=== Improvement ===

Due to the constant changes of the Linux kernel, GNU software, etc. this
document will be outdated very quick. To avoid this, help is always appreciated
improving this document. If you can update, improve, add or complete this
document, don't hesitate to do so.

== Prepare/install cross compile system ==

To perform the cross-compilation a cross compiler and QEmu must be installed
on the desktop computer. QEmu will help a lot for compiling packages which
will not properly cross compile.

=== Install cross compiling system ===

For compiling software for an ARM controller a cross compiler must be installed.

We can use ARMv7 using either soft float (armv7a-softfp-linux-gnueabi) or hard
float (armv7a-hardfloat-linux-gnueabi).

<pre>export CROSSDEV_TARGET=armv7a-softfp-linux-gnueabi</pre>

or

<pre>export CROSSDEV_TARGET=armv7a-hardfloat-linux-gnueabi</pre>

The additional portage tree in "/usr/local/portage-crossdev" will hold all
information for emerging the cross build system (cross compiler and tools).

To prepare emerging a cross compiler, execute the following commands.

<pre>
su
umask 0022

emerge -av crossdev

mkdir -p /usr/local/portage-crossdev/{profiles,metadata}

echo 'local-crossdev' >/usr/local/portage-crossdev/profiles/repo_name
echo 'masters = gentoo' >/usr/local/portage-crossdev/metadata/layout.conf
echo 'thin-manifests = true' >>/usr/local/portage-crossdev/metadata/layout.conf
chown -R portage:portage /usr/local/portage-crossdev

echo '[local-crossdev]' >/etc/portage/repos.conf/crossdev.conf

echo 'location = /usr/local/portage-crossdev' \
>>/etc/portage/repos.conf/crossdev.conf

echo 'priority = 10' >>/etc/portage/repos.conf/crossdev.conf
echo 'masters = gentoo' >>/etc/portage/repos.conf/crossdev.conf
echo 'auto-sync = no' >>/etc/portage/repos.conf/crossdev.conf
</pre>

The portage tree for emerging the cross build system is set up. Now we have to
find out which versions of the cross build components are about to be installed.
The target system will get binutils, gcc, glibc and linux-headers of a certain
version. The same version should be installed in the cross build system.

<pre>
export BINUTILS_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-devel/binutils/binutils-*.ebuild | tail -1 | \
awk 'match($0, ".*/binutils-(.*).ebuild", v) { print(v[1]); }')

export GCC_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-devel/gcc/gcc-*.ebuild | tail -1 | \
awk 'match($0, ".*/gcc-(.*).ebuild", v) { print(v[1]); }')

export GLIBC_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-libs/glibc/glibc-*.ebuild | tail -1 | \
awk 'match($0, ".*/glibc-(.*).ebuild", v) { print(v[1]); }')

export LINUX_HEADERS_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-kernel/linux-headers/linux-headers-*.ebuild | tail -1 | \
awk 'match($0, ".*/linux-headers-(.*).ebuild", v) { print(v[1]); }')
</pre>

Now emerge the cross compiler.

<pre>
crossdev --binutils $BINUTILS_VER --gcc $GCC_VER --libc $GLIBC_VER \
--kernel $LINUX_HEADERS_VER --target $CROSSDEV_TARGET
</pre>

=== Install QEmu ===

A lot of packages will not cross compile properly. QEmu will help for these
packages. Install it to emulate an ARM controller.

Edit /etc/portage/make.conf.

<pre>
nano /etc/portage/make.conf
</pre>

And add the following lines.

<pre>
QEMU_SOFTMMU_TARGETS=""
QEMU_USER_TARGETS="arm"
</pre>

Also enable the use flag static-user. This builds QEmu as static binary.
QEmu will be used later in a chroot environment of an ARM controller and will
be unable to access needed shared libraries. So it must contain all these
libraries by building it in a static way.

<pre>
euse -E static-user
</pre>

All the needed libraries for QEmu must also be available as library archive
(static libs). Emerging QEmu will request to emerge these libraries as
static variants, also. Create and add these libraries in the file
"/etc/portage/package.use/qemu". Look which libraries are needed.

<pre>
emerge -pv qemu
</pre>

And add them with the use flag static-libs. Here is an Example:

<pre>
>=net-misc/curl-7.53.0 static-libs
>=sys-apps/attr-2.4.47-r2 static-libs
>=media-libs/libsdl-1.2.15-r9 static-libs
>=sys-apps/dtc-1.4.1 static-libs
>=app-arch/bzip2-1.0.6-r7 static-libs
>=x11-libs/pixman-0.34.0 static-libs
>=dev-libs/libpcre-8.40-r1 static-libs
>=sys-libs/libseccomp-2.3.0 static-libs
>=net-fs/libnfs-1.9.7 static-libs
>=dev-libs/cyrus-sasl-2.1.26-r9 static-libs
>=dev-libs/gmp-6.1.0 static-libs
>=dev-libs/libaio-0.3.110 static-libs
>=sys-fs/xfsprogs-4.5.0 static-libs
>=sys-libs/zlib-1.2.11 static-libs
>=media-libs/libjpeg-turbo-1.5.0 static-libs
>=sys-libs/libcap-ng-0.7.8 static-libs
>=dev-libs/openssl-1.0.2k static-libs
>=dev-libs/glib-2.50.3-r1 static-libs
>=virtual/jpeg-0-r2:0 static-libs
>=media-libs/libpng-1.6.27 static-libs
>=sys-libs/ncurses-6.0-r1 static-libs
</pre>

Emerge QEmu.

<pre>
emerge qemu
udevadm trigger -c add /dev/kvm
</pre>

QEmu will execute ARM binaries on the desktop computer as if it would have an
ARM controller. To achieve this, register foreign binaries and start the
systemd service.

<pre>
ln -s /usr/share/qemu/binfmt.d/qemu.conf /etc/binfmt.d/qemu.conf
systemctl start systemd-binfmt
</pre>

Now our desktop computer is able to execute ARM binaries as well as his own
binaries.

=== Install GIT ===

To get the kernel sources, GIT will be needed. Emerge it.

<pre>
emerge git
</pre>

Exit the root shell.

<pre>
exit
</pre>

Now the cross build system is ready to compile a Gentoo Linux for the Pandora.

== Prepare target file system ==

To build the system for the Pandora about 10 GB disk space is needed. Create a
directory "CrossDev" to store all data there.

<pre>
mkdir CrossDev
cd CrossDev
</pre>

In this directory two more directories will be created:

* One to store and build the Linux kernel.
* Another will store the whole system for the Pandora including QEmu which is not really a part of the system for Pandora, but it is needed as long as the building process runs.
* Some files and archives.

First get the Gentoo base system "stage3-armv7a-*.tar.bz2". Download it from
a suitable mirror of the Gentoo distribution. See
https://www.gentoo.org/downloads/mirrors for a list of mirrors.

Go to the directory "releases/arm/autobuilds". According to your target, enter

* "current-stage3-armv7a" for soft float (armv7a-softfp-linux-gnueabi),
* "current-stage3-armv7a_hardfp" for hard float (armv7a-hardfloat-linux-gnueabi).

There is a stage 3 file for ARMv7. Download this archive.

Example:

<pre>
wget http://mirror.eu.oneandone.net/linux/distributions/gentoo/gentoo/\
releases/arm/autobuilds/current-stage3-armv7a/stage3-armv7a-20161129.tar.bz2
</pre>

or

<pre>
wget http://mirror.eu.oneandone.net/linux/distributions/gentoo/gentoo/\
releases/arm/autobuilds/current-stage3-armv7a_hardfp/\
stage3-armv7a_hardfp-20161129.tar.bz2
</pre>

As long as we are cross compiling, we use "/usr/$CROSSDEV_TARGET" as working
directory. The cross compiler looks for libraries there and uses many references
to this directory. That's why "/usr/$CROSSDEV_TARGET" will be saved, so it can
be restored after the build.

<pre>
su
umask 0022
tar -cpjf ${CROSSDEV_TARGET}-saved.tar.bz2 -C /usr $CROSSDEV_TARGET
</pre>

Unpack the stage 3 archive into "/usr/$CROSSDEV_TARGET".

<pre>
tar --xattrs --numeric-owner -xpjf stage3-*.tar.bz2 -C /usr/$CROSSDEV_TARGET
</pre>

Sometimes there is a lot of garbage in the "tmp" directory. Remove it.

<pre>
rm -rf /usr/$CROSSDEV_TARGET/tmp/*
</pre>

Exit the root shell and go back to our working directory.

<pre>
exit
</pre>

== Compile/install kernel ==

The standard Gentoo kernel will not run on the Pandora (or, at least, takes too
much effort to make it run), so download a current kernel from
https://goldelico.com using GIT.

=== Download kernel ===

Download the kernel with GIT.

<pre>
git clone git://git.goldelico.com/gta04-kernel.git
cd gta04-kernel
</pre>

=== Compile kernel ===

Prepare an environment to cross compile the kernel. First call another shell
instance for saving the current environment. This instance is not really
necessary but it is more convenient because the saved environment is restored
after exiting the new shell.

<pre>
bash
umask 0022
export ARCH=arm CROSS_COMPILE=${CROSSDEV_TARGET}-
export PS1="($ARCH) $PS1"
</pre>

The kernel does not support the blue symbols on the keys used by "Fn". To enable
this, patch the kernel using the patch file [[Cross Install Gentoo kernel-patch-Fn-keys.txt|kernel-patch-Fn-keys.txt]].

<pre>
patch -p1 <../kernel-patch-Fn-keys.txt
</pre>

This patches the files "arch/arm/boot/dts/omap3-pandora-common.dtsi" which will
get more key codes for the blue symbols and
"drivers/input/keyboard/twl4030_keypad.c" which will handle the keys.

Now a default configuration for the kernel will be created.

<pre>
make omap2plus_defconfig
</pre>

A lot of configuration must be done to make the kernel work. To ease this use
[[Cross Install Gentoo kernel-config|kernel-config]] which will configure a running
kernel for the Pandora. It uses the name "pherkad" as computer name. Change
this to any name you like in the config file. Calling oldconfig might be
necessary if "kernel-config" is too old for the current gta04-kernel.

<pre>
cp ../kernel-config .config
make oldconfig
make menuconfig
</pre>

In "General setup/Local version" change "-pherkad" to any name you like. But
use "-" as prefix.

Build the kernel and the device tree "omap3-pandora-600mhz.dtb". Pandora users
with 1 GHz units can use "omap3-pandora-1ghz.dts". Use as much CPU cores as you
have for the compiling process.

<pre>
export CPUS="$(grep processor /proc/cpuinfo | wc -l)"
make -j$CPUS zImage
make -j$CPUS modules
make omap3-pandora-600mhz.dtb
</pre>

Convert the kernel into an image for the U-Boot loader. Use any name you
like for "Linux-pherkad".

<pre>
mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008000 -n \
'Linux-pherkad' -d arch/arm/boot/zImage arch/arm/boot/uImage
</pre>

Generate a "boot.scr" file which loads the kernel image and the correct device
tree.

Keep an eye to the bootargs. It uses the following commands:

* Start the systemd as init process: "init=/lib/systemd/systemd".
* Be quiet: "quiet". This can be removed while development.
* Show a splash screen: "splash". There is currently no splash screen, so this
* Use the root file system at: "root=/dev/mmcblk0p2". Take care to use the same partition as described below.
* Use Ext 4 root file system: "rootfstype=ext4".
* Wait for root file system: "rootwait".
* Mount initially read only: "ro". systemd will remount it later as RW.
* Use the following SWAP partition for hibernation/resume: "resume=/dev/mmcblk0p3". This is currently not used.

The file "boot.txt" will be converted to the boot script "boot.src".

<pre>
cat >boot.txt <<EOF
if itest.w *0x4830a204 == 0x102f
then
setenv devicetree omap3-pandora-1ghz
else
setenv devicetree omap3-pandora-600mhz
fi
setenv defaultdisplay lcd
setenv bootargs "init=/lib/systemd/systemd quiet splash \
root=/dev/mmcblk0p2 rootfstype=ext4 rootwait ro resume=/dev/mmcblk0p3"
ext2load mmc 0:1 0x825f0000 /boot/\${devicetree}.dtb
ext2load mmc 0:1 0x80300000 /boot/uImage-pherkad
bootm 0x80300000 - 0x825f0000
EOF

mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n 'Boot script' \
-d boot.txt boot.scr
</pre>

Exit the kernel build environment.

<pre>
exit
</pre>

=== Install kernel ===

The installation of the kernel into the target directory must be done as root.
Create the "boot" directory for the kernel, device tree and boot script and
copy them to the target directory.

<pre>
su
umask 0022
cp arch/arm/boot/uImage /usr/$CROSSDEV_TARGET/boot/uImage-pherkad
cp .config /usr/$CROSSDEV_TARGET/boot/config-pherkad
cp System.map /usr/$CROSSDEV_TARGET/boot/System.map-pherkad
cp arch/arm/boot/dts/omap3-pandora-600mhz.dtb /usr/$CROSSDEV_TARGET/boot/.
cp boot.scr /usr/$CROSSDEV_TARGET/boot/.
</pre>

Create a link for the boot directory. This is used if the boot directory is an
own partition and the boot loader wants to load the kernel from "boot/uImage-*".
In our case it is not really necessary.

<pre>
(cd /usr/$CROSSDEV_TARGET/boot; ln -s . boot)
</pre>

Install all kernel modules into "target/lib/modules". The symbolic link is for
the cross compiling process to find the kernel configuration.

<pre>
make ARCH=arm CROSS_COMPILE=${CROSSDEV_TARGET}- \
INSTALL_MOD_PATH=/usr/$CROSSDEV_TARGET modules_install

(DIR="$PWD"; cd /usr/$CROSSDEV_TARGET/usr/src; ln -s $DIR linux)
cd ..
</pre>

== Compile system ==

Now it's time to cross compile the whole Gentoo system. The base system is
already installed in the "target" directory. All the binaries there will
be compiled again with our own cross compiler. Also a lot of new packages
(more binaries) will be installed.

=== Prepare cross development system ===

Go to the target and copy all portage configurations from the desktop computer
to the target system, since we want to use the desktop computer system as
base of the Pandora system. This must be done as root.

<pre>
export FROM_DIR="$PWD"
cd /usr/$CROSSDEV_TARGET
</pre>

Edit the "make.conf" file.

<pre>
nano etc/portage/make.conf
</pre>

Change some of the lines there. You might copy some of the contents from
the desktop computer but be sure to have the same CHOST as the CROSSDEV_TARGET.
Especially add or change for the following:

<pre>
CFLAGS="-O2 -pipe -march=armv7-a -mfpu=vfpv3-d16 -mfloat-abi=softfp \
-mfpu=neon -fno-stack-protector"
</pre>

or

<pre>
CFLAGS="-O2 -pipe -march=armv7-a -mfpu=vfpv3-d16 -mfloat-abi=hard \
-mfpu=neon -fno-stack-protector"
</pre>

GENTOO_MIRRORS="<enter your mirrors>"
PKGDIR="/usr/portage/packages/${CHOST}"
</pre>

It is recommended to activate the build of binary packages. The cross
compilation will fail to build some packages, so QEmu will build all packages
again. It is not necessary to build good cross compiled packages by QEmu again.
Using binary packages will avoid this and save a lot of time.

To avoid mixing up the binary packages of the desktop comuter and the Pandora
set PKGDIR accordingly. Example: "/usr/portage/packages/${CHOST}"

Also copy and edit some package specific files from your desktop computer.

<pre>
cp -r /etc/portage/package.* etc/portage/.
</pre>

Edit the files in "etc/portage/package.*" and configure the portage tree.

<pre>
sed -i "s/amd64/arm/g" etc/portage/package.keywords/*
rm -r etc/portage/package.keywords/cross*
rm -r etc/portage/package.mask/cross*
rm etc/portage/package.use/cross*
rm etc/portage/package.env/cross*

mkdir etc/portage/repos.conf
cp usr/share/portage/config/repos.conf etc/portage/repos.conf/gentoo.conf
rm -f etc/portage/make.profile

(cd etc/portage && \
ln -s /usr/portage/profiles/default/linux/arm/13.0/armv7a/desktop make.profile)
</pre>

Copy the world file from the desktop computer and remove all packages which
should not be installed on the Pandora system.

<pre>
cp /var/lib/portage/world var/lib/portage/world
nano var/lib/portage/world
</pre>

=== Prepare cross-compilation and QEmu environment ===

A lot of packages will fail but we will keep going the emerge process and
compile the failed packages again with QEmu.

But first update the compiler tools in the target system. They will be needed
later in the QEmu environment. If they fail here, try to do it in the QEmu
part.

Copy the static QEmu binary to the target system and set up portage for the
target system.

<pre>
cp /usr/bin/qemu-arm usr/bin/.
mkdir -p usr/portage
touch usr/portage/.keep
</pre>

Do some standard setup for the target system. Copy some personal configurations
to the root account.

<pre>
cp -L /etc/resolv.conf etc/.
cp -r etc/skel/. root/.

cp /root/.bashrc /root/.dir_colors /root/.screenrc /root/.toprc \
/root/.xsession root/.
</pre>

Some nice tools like htop are worth to install them on the Pandora.

<pre>
mkdir -m0700 root/.config
cp -r /root/.config/htop root/.config/.
</pre>

To access the root account with ssh, copy its configuration. This copies the
"id_*" files, also. Don't do this if you deliberately take care about security.

<pre>
cp -r /root/.ssh/. root/.ssh/.
</pre>

=== Start cross compilation ===

Set up a cross compilation environment (use a third shell instance).

<pre>
bash
export CBUILD=x86_64-pc-linux-gnu
export CHOST=$CROSSDEV_TARGET
export ROOT=$PWD
export PORTAGE_CONFIGROOT=$ROOT
export PS1="($CHOST) $PS1"
</pre>

Try to cross compile all packages.

<pre>
$CHOST-emerge -a binutils glibc linux-headers gcc
$CHOST-emerge -ae @world
</pre>

If one of them fails, save the resume list.

<pre>
$CHOST-emerge -p --resume | grep "^\[[eb].*\]" | grep -ve "^\[blocks" | \
cut -b 18- | cut -d " " -f1 | awk '{ print("=" $0); }' >tmp/packages.txt
</pre>

Now go to "Continue cross-compilation with QEmu".

=== Continue cross-compilation with QEmu ===

Enter the chroot environment and emerge the failed package again (the first one
in the packages.txt file).

The portage tree will be mounted into the target system.

In the chroot environment it might be necessary to switch the compiler. Check
if the same version of gcc is used than the cross compiler with
"gcc-config -l". Set the correct version before starting "emerge".

<pre>
mkdir -p $PWD/run/systemd/resolve
cp /run/systemd/resolve/resolv.conf $PWD/run/systemd/resolve/.
mount --rbind /proc $PWD/proc
mount --make-rslave $PWD/proc
mount --rbind /sys $PWD/sys
mount --make-rslave $PWD/sys
mount --rbind /dev $PWD/dev
mount --make-rslave $PWD/dev
mount --rbind /usr/portage $PWD/usr/portage
chroot $PWD /bin/bash
unset CBUILD CHOST ROOT PORTAGE_CONFIGROOT
env-update
source /etc/profile
cd
source ./.bashrc
export PS1="(chroot) $PS1"
emerge -aB1 $(head -1 /tmp/packages.txt)
exit
umount -l usr/portage
umount -l dev sys proc
</pre>

After fixing the failed package(s), continue with the cross compiler.

<pre>
cat tmp/packages.txt | xargs $CHOST-emerge -1
</pre>

If one of them fails again, save the resume list.

<pre>
$CHOST-emerge -p --resume | grep "^\[[eb].*\]" | grep -ve "^\[blocks" | \
cut -b 18- | cut -d " " -f1 | awk '{ print("=" $0); }' >tmp/packages.txt
</pre>

*Go back to "Continue cross-compilation with QEmu" until all packages are merged
successfully.*

Remove some leftover temporary files.

<pre>
rm -rf /var/tmp/portage/* /usr/$CROSSDEV_TARGET/var/tmp/portage/* \
/usr/$CROSSDEV_TARGET/tmp/packages.txt
</pre>

== Fix lib64-problem ==

Some cross compiled packages install their libraries into the "lib64" directory.
This is not used on the Pandora. So we have to copy all contents from "lib64"
to "lib" and set a link for "lib64".

<pre>
rsync -avc usr/lib64/. usr/lib/.
rm -rf usr/lib64
(cd usr && ln -s lib lib64)
</pre>

== Configure system ==

Set the key map for Pandora in the console and, as usual in Gentoo,
configure the target system.

Use to make the Pandora keyboard work on the console.
([[Cross Install Gentoo Keymap-pandora.map|keymap-pandora.map]])

<pre>
cp "$FROM_DIR/keymap-pandora.map" etc/.
chmod 644 etc/keymap-pandora.map
echo >etc/vconsole.conf "KEYMAP=/etc/keymap-pandora.map"
echo >>etc/vconsole.conf "FONT=eurlatgr"
</pre>

Set up the mount table. Every line in "etc/fstab" will be commented out and
new entries added. The file system labels are used to mount the partitions.

<pre>
sed -ie "s,^/,#/,g" etc/fstab

cat >>etc/fstab <<EOF
LABEL=phlnx_boot /boot ext2 noauto,noatime 1 2
LABEL=phlnx_root / ext4 errors=remount-ro,noatime 1 1
LABEL=phlnx_home /home ext4 noauto,noatime,nodev,nosuid 1 2
EOF
</pre>

Enter the chroot environment again.

<pre>
mount --rbind /proc $PWD/proc
mount --make-rslave $PWD/proc
mount --rbind /sys $PWD/sys
mount --make-rslave $PWD/sys
mount --rbind /dev $PWD/dev

mount --rbind /usr/portage $PWD/usr/portage
chroot $PWD /bin/bash
unset CBUILD CHOST ROOT PORTAGE_CONFIGROOT
env-update
source /etc/profile
cd
source ./.bashrc
export PS1="(chroot) $PS1"
</pre>

Set a password for root.

<pre>
passwd
</pre>

Update the configuration files and read/clear all news from portage.

<pre>
dispatch-conf
eselect news list
eselect news read
eselect news purge
</pre>

Enter the time zone and generate the locale info you want (example: enable all
lines with en_US and de_DE).

<pre>
echo "Europe/Berlin" >/etc/timezone
emerge --config sys-libs/timezone-data
nano -w /etc/locale.gen
locale-gen
</pre>

Use en_US.utf8 (entry #9) as locale.

<pre>
eselect locale list
eselect locale set 9
</pre>

Set up mount table, the machine ID and host name.

<pre>
ln -sf /proc/self/mounts /etc/mtab
systemd-machine-id-setup
echo >/etc/machine-info "PRETTY_HOSTNAME=Pherkad"
echo >/etc/hostname "pherkad"
ln -snf /run/systemd/resolve/resolv.conf /etc/resolv.conf
systemctl enable systemd-resolved.service
</pre>

Exit the chroot environment.

<pre>
exit
umount -l usr/portage
umount -l dev sys proc
</pre>

Remove the QEmu binary. It is not used anymore.

<pre>
rm usr/bin/qemu-arm
</pre>

Also remove some leftovers from the cross compiler and the link to our kernel
sources.

<pre>
rm -f etc/portage/profile/package.provided
rm -f sys-include
rm -f usr/src/linux
</pre>

Copy back the target system and restore the previous cross compiler state.

<pre>
cd "$FROM_DIR"
mkdir $CROSSDEV_TARGET

rm -rf /usr/$CROSSDEV_TARGET
tar -xpjf ${CROSSDEV_TARGET}-saved.tar.bz2 -C /usr
rm ${CROSSDEV_TARGET}-saved.tar.bz2
</pre>

Exit the root shell.

<pre>
exit
</pre>

= Update system =

To update the system, use a similar approach as in the cross compilation phase.
Define CROSSDEV_TARGET as in "Install cross compiling system".

== Start cross-compilation ==

Set up a cross compilation environment (become root and use a second shell
instance again).

<pre>
cd CrossDev
su

= Create SD-card partitions phlnx_boot/root/swap/home =

Finally the target system is done. Now it's time to copy it to the Pandora.

== Pandora ==

It's recommended to partition the SD-card for the target system on the Pandora.
Otherwise the boot loader might refuse to work.

Insert the SD-card in the left slot (mmcblk0) and unmount it if necessary.

Create the following partitions:

* A boot partition (ext2).
* A root partition which will contain the target system (at least 4 GB).
* A home partition which we can use later.
* A SWAP partition which we can use later.

<pre>
sudo -s

/sbin/fdisk /dev/mmcblk0
Create new DOS partition label: o
Create new partition: n p 1 Return +8M
Create new partition: n p 2 Return +4G
Create new partition: n p 3 Return +1G
Change partition type: t 3 82 (Linux swap)
Create new partition: n p Return Return
Write all changes: w

/sbin/mkfs.ext2 -FL phlnx_boot /dev/mmcblk0p1
/sbin/mkfs.ext4 -FL phlnx_root -O ^has_journal /dev/mmcblk0p2
/sbin/mkswap -L phlnx_swap /dev/mmcblk0p3
/sbin/mkfs.ext4 -FL phlnx_home -O ^has_journal /dev/mmcblk0p4
exit
</pre>

= Option #1: Copy target system to SD-card =

One of the possibilities to copy the target system to the SD-card on the Pandora
is to use a USB cable connecting the Pandora to the desktop computer.

It's also possible to copy it via the WiFi network (see below).

== Pandora ==

Connect the Pandora via USB to the desktop computer. Insert the SD-card in the
left slot (mmcblk0). Use menu "System/SD-Mass Storage" to access partition
"phlnx_root".

== Desktop computer ==

Mount the root partition and copy the target system. Use the correct "/dev/sd*".

<pre>
su
mkdir /tmp/mnt
mount /dev/sdc /tmp/mnt
mkdir -p /tmp/mnt/boot
touch /tmp/mnt/boot/.keep
mkdir -p /tmp/mnt/home
touch /tmp/mnt/home/.keep

rsync -av --delete --exclude lost+found --exclude /boot \
CrossDev/$CROSSDEV_TARGET/. /tmp/mnt/.

umount /tmp/mnt
</pre>

== Pandora ==

Use "System/SD-Mass Storage" again to access phlnx_boot.

== Desktop computer ==

Mount the boot partition and copy boot directory of the target system.

<pre>
mount /dev/sdc /tmp/mnt
rm -f /tmp/mnt/uImage-pherkad

rsync -av --delete --exclude lost+found \
CrossDev/$CROSSDEV_TARGET/boot/. /tmp/mnt/.

umount /tmp/mnt
rmdir /tmp/mnt
exit
</pre>

== Pandora ==

End SD-Mass Storage.

= Option #2: Copy target system to SD-card via WiFi network =

== Pandora ==

Copy all files from the desktop computer to the SD-card partitions. Use the
same CROSSDEV_TARGET and FROM_DIR environment settings as on the desktop
computer.

<pre>
sudo -s
export REMOTE=mizar.spdns.de
export FROM_DIR=/home/jgeiss/Data/Systems/Pandora/Pherkad/Linux/Gentoo/CrossDev
export CROSSDEV_TARGET=armv7a-hardfloat-linux-gnueabi

mkdir -p /media/phlnx_root/boot
touch /media/phlnx_root/boot/.keep

rsync -av --numeric-ids --delete --exclude lost+found --exclude /boot \
$REMOTE:$FROM_DIR/$CROSSDEV_TARGET/. /media/phlnx_root/.

rsync -av --delete --exclude lost+found \
$REMOTE:$FROM_DIR/$CROSSDEV_TARGET/boot/. /media/phlnx_boot/.

exit
</pre>

= Boot the new system =

Reboot the Pandora and hold the right shoulder button until the boot menu
appears.

'''Sometimes it is necessary to switch off the Pandora for 10-60 seconds.'''

Choose "boot from SD1:1".

It the boot works well, login as root and play around.

== Optional: USB-networking ==

To use networking to the desktop computer via USB cable, execute the
following commands on both systems.

=== Pandora ===

<pre>
modprobe g_ether
ifconfig usb0 192.168.129.3 netmask 255.255.255.0
route add default gw 192.168.129.2
systemctl start sshd
</pre>

=== Desktop computer ===

Configure the corresponding network interface.

<pre>
ifconfig enp0s20u1u1 192.168.129.2 netmask 255.255.255.0
</pre>

Now you should be able to connect to the Pandora.

<pre>
ssh root@192.168.129.3
</pre>

== Shutdown Pandora ==

To shutdown the Pandora system enter the following command.

<pre>
systemctl poweroff
</pre>

= Open issues =

The following things are currently not working and need to be implemented/fixed:

* wl1251 board initialization failed
* tw1: not initialized
* omapfb omapfb: no displays, failed to setup omapfb
* omap2_set_init_voltage: unable to find boot up OPP vor ...
* __nand_correct_data: uncorrectable ECC error
* Buffer I/O error on dev mtdblock0, logical block 0, async page read
* Cursor and other GPIO-related keys do not work correctly if CPU is idle. Workaround: echo 1 >/sys/devices/system/cpu/cpu0/cpuidle/state4/disable
* Kernel panic at system shutdown
* fstab: Auto-Mounting /boot or /home causes system suspend after about 30 Seconds.

Cross Install Gentoo

2018-06-05T06:38:04Z

Jgeiss: Links to files fixed

= Cross install Gentoo Linux on Pandora =

== Introduction ==

These instructions are for installing a recent Gentoo Linux on the OpenPandora
handheld console. The system will be installed and booted from a SD-card. The
Gentoo Linux will be cross-compiled on another desktop computer also running
Gentoo Linux.

It is not necessary to follow all instructions exactly. Some of them can be
changed to your own needs.

'''The system currently supports only the text console and no X11 or sound.'''
'''Also a lot of features are missing.''' See "Open issues" at the end.

=== Prerequisites ===

These instructions assume the following prerequisites:

* Good knowledge in Gentoo Linux.
* A desktop computer running Gentoo Linux. Other Linux is, of course, also possible but requires proper adaption of these instructions.
* An OpenPandora handheld console.
* A SD-card with least 8 GB size.
* A USB cable to connect the Pandora to the desktop computer.

=== Improvement ===

Due to the constant changes of the Linux kernel, GNU software, etc. this
document will be outdated very quick. To avoid this, help is always appreciated
improving this document. If you can update, improve, add or complete this
document, don't hesitate to do so.

== Prepare/install cross compile system ==

To perform the cross-compilation a cross compiler and QEmu must be installed
on the desktop computer. QEmu will help a lot for compiling packages which
will not properly cross compile.

=== Install cross compiling system ===

For compiling software for an ARM controller a cross compiler must be installed.

We can use ARMv7 using either soft float (armv7a-softfp-linux-gnueabi) or hard
float (armv7a-hardfloat-linux-gnueabi).

<pre>export CROSSDEV_TARGET=armv7a-softfp-linux-gnueabi</pre>

or

<pre>export CROSSDEV_TARGET=armv7a-hardfloat-linux-gnueabi</pre>

The additional portage tree in "/usr/local/portage-crossdev" will hold all
information for emerging the cross build system (cross compiler and tools).

To prepare emerging a cross compiler, execute the following commands.

<pre>
su
umask 0022

emerge -av crossdev

mkdir -p /usr/local/portage-crossdev/{profiles,metadata}

echo 'local-crossdev' >/usr/local/portage-crossdev/profiles/repo_name
echo 'masters = gentoo' >/usr/local/portage-crossdev/metadata/layout.conf
echo 'thin-manifests = true' >>/usr/local/portage-crossdev/metadata/layout.conf
chown -R portage:portage /usr/local/portage-crossdev

echo '[local-crossdev]' >/etc/portage/repos.conf/crossdev.conf

echo 'location = /usr/local/portage-crossdev' \
>>/etc/portage/repos.conf/crossdev.conf

echo 'priority = 10' >>/etc/portage/repos.conf/crossdev.conf
echo 'masters = gentoo' >>/etc/portage/repos.conf/crossdev.conf
echo 'auto-sync = no' >>/etc/portage/repos.conf/crossdev.conf
</pre>

The portage tree for emerging the cross build system is set up. Now we have to
find out which versions of the cross build components are about to be installed.
The target system will get binutils, gcc, glibc and linux-headers of a certain
version. The same version should be installed in the cross build system.

<pre>
export BINUTILS_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-devel/binutils/binutils-*.ebuild | tail -1 | \
awk 'match($0, ".*/binutils-(.*).ebuild", v) { print(v[1]); }')

export GCC_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-devel/gcc/gcc-*.ebuild | tail -1 | \
awk 'match($0, ".*/gcc-(.*).ebuild", v) { print(v[1]); }')

export GLIBC_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-libs/glibc/glibc-*.ebuild | tail -1 | \
awk 'match($0, ".*/glibc-(.*).ebuild", v) { print(v[1]); }')

export LINUX_HEADERS_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-kernel/linux-headers/linux-headers-*.ebuild | tail -1 | \
awk 'match($0, ".*/linux-headers-(.*).ebuild", v) { print(v[1]); }')
</pre>

Now emerge the cross compiler.

<pre>
crossdev --binutils $BINUTILS_VER --gcc $GCC_VER --libc $GLIBC_VER \
--kernel $LINUX_HEADERS_VER --target $CROSSDEV_TARGET
</pre>

=== Install QEmu ===

A lot of packages will not cross compile properly. QEmu will help for these
packages. Install it to emulate an ARM controller.

Edit /etc/portage/make.conf.

<pre>
nano /etc/portage/make.conf
</pre>

And add the following lines.

<pre>
QEMU_SOFTMMU_TARGETS=""
QEMU_USER_TARGETS="arm"
</pre>

Also enable the use flag static-user. This builds QEmu as static binary.
QEmu will be used later in a chroot environment of an ARM controller and will
be unable to access needed shared libraries. So it must contain all these
libraries by building it in a static way.

<pre>
euse -E static-user
</pre>

All the needed libraries for QEmu must also be available as library archive
(static libs). Emerging QEmu will request to emerge these libraries as
static variants, also. Create and add these libraries in the file
"/etc/portage/package.use/qemu". Look which libraries are needed.

<pre>
emerge -pv qemu
</pre>

And add them with the use flag static-libs. Here is an Example:

<pre>
>=net-misc/curl-7.53.0 static-libs
>=sys-apps/attr-2.4.47-r2 static-libs
>=media-libs/libsdl-1.2.15-r9 static-libs
>=sys-apps/dtc-1.4.1 static-libs
>=app-arch/bzip2-1.0.6-r7 static-libs
>=x11-libs/pixman-0.34.0 static-libs
>=dev-libs/libpcre-8.40-r1 static-libs
>=sys-libs/libseccomp-2.3.0 static-libs
>=net-fs/libnfs-1.9.7 static-libs
>=dev-libs/cyrus-sasl-2.1.26-r9 static-libs
>=dev-libs/gmp-6.1.0 static-libs
>=dev-libs/libaio-0.3.110 static-libs
>=sys-fs/xfsprogs-4.5.0 static-libs
>=sys-libs/zlib-1.2.11 static-libs
>=media-libs/libjpeg-turbo-1.5.0 static-libs
>=sys-libs/libcap-ng-0.7.8 static-libs
>=dev-libs/openssl-1.0.2k static-libs
>=dev-libs/glib-2.50.3-r1 static-libs
>=virtual/jpeg-0-r2:0 static-libs
>=media-libs/libpng-1.6.27 static-libs
>=sys-libs/ncurses-6.0-r1 static-libs
</pre>

Emerge QEmu.

<pre>
emerge qemu
udevadm trigger -c add /dev/kvm
</pre>

QEmu will execute ARM binaries on the desktop computer as if it would have an
ARM controller. To achieve this, register foreign binaries and start the
systemd service.

<pre>
ln -s /usr/share/qemu/binfmt.d/qemu.conf /etc/binfmt.d/qemu.conf
systemctl start systemd-binfmt
</pre>

Now our desktop computer is able to execute ARM binaries as well as his own
binaries.

=== Install GIT ===

To get the kernel sources, GIT will be needed. Emerge it.

<pre>
emerge git
</pre>

Exit the root shell.

<pre>
exit
</pre>

Now the cross build system is ready to compile a Gentoo Linux for the Pandora.

== Prepare target file system ==

To build the system for the Pandora about 10 GB disk space is needed. Create a
directory "CrossDev" to store all data there.

<pre>
mkdir CrossDev
cd CrossDev
</pre>

In this directory two more directories will be created:

* One to store and build the Linux kernel.
* Another will store the whole system for the Pandora including QEmu which is not really a part of the system for Pandora, but it is needed as long as the building process runs.
* Some files and archives.

First get the Gentoo base system "stage3-armv7a-*.tar.bz2". Download it from
a suitable mirror of the Gentoo distribution. See
https://www.gentoo.org/downloads/mirrors for a list of mirrors.

Go to the directory "releases/arm/autobuilds". According to your target, enter

* "current-stage3-armv7a" for soft float (armv7a-softfp-linux-gnueabi),
* "current-stage3-armv7a_hardfp" for hard float (armv7a-hardfloat-linux-gnueabi).

There is a stage 3 file for ARMv7. Download this archive.

Example:

<pre>
wget http://mirror.eu.oneandone.net/linux/distributions/gentoo/gentoo/\
releases/arm/autobuilds/current-stage3-armv7a/stage3-armv7a-20161129.tar.bz2
</pre>

or

<pre>
wget http://mirror.eu.oneandone.net/linux/distributions/gentoo/gentoo/\
releases/arm/autobuilds/current-stage3-armv7a_hardfp/\
stage3-armv7a_hardfp-20161129.tar.bz2
</pre>

As long as we are cross compiling, we use "/usr/$CROSSDEV_TARGET" as working
directory. The cross compiler looks for libraries there and uses many references
to this directory. That's why "/usr/$CROSSDEV_TARGET" will be saved, so it can
be restored after the build.

<pre>
su
umask 0022
tar -cpjf ${CROSSDEV_TARGET}-saved.tar.bz2 -C /usr $CROSSDEV_TARGET
</pre>

Unpack the stage 3 archive into "/usr/$CROSSDEV_TARGET".

<pre>
tar --xattrs --numeric-owner -xpjf stage3-*.tar.bz2 -C /usr/$CROSSDEV_TARGET
</pre>

Sometimes there is a lot of garbage in the "tmp" directory. Remove it.

<pre>
rm -rf /usr/$CROSSDEV_TARGET/tmp/*
</pre>

Exit the root shell and go back to our working directory.

<pre>
exit
</pre>

== Compile/install kernel ==

The standard Gentoo kernel will not run on the Pandora (or, at least, takes too
much effort to make it run), so download a current kernel from
https://goldelico.com using GIT.

=== Download kernel ===

Download the kernel with GIT.

<pre>
git clone git://git.goldelico.com/gta04-kernel.git
cd gta04-kernel
</pre>

=== Compile kernel ===

Prepare an environment to cross compile the kernel. First call another shell
instance for saving the current environment. This instance is not really
necessary but it is more convenient because the saved environment is restored
after exiting the new shell.

<pre>
bash
umask 0022
export ARCH=arm CROSS_COMPILE=${CROSSDEV_TARGET}-
export PS1="($ARCH) $PS1"
</pre>

The kernel does not support the blue symbols on the keys used by "Fn". To enable
this, patch the kernel using the patch file [[Cross Install Gentoo kernel-patch-Fn-keys.txt|kernel-patch-Fn-keys.txt]].

<pre>
patch -p1 <../kernel-patch-Fn-keys.txt
</pre>

This patches the files "arch/arm/boot/dts/omap3-pandora-common.dtsi" which will
get more key codes for the blue symbols and
"drivers/input/keyboard/twl4030_keypad.c" which will handle the keys.

Now a default configuration for the kernel will be created.

<pre>
make omap2plus_defconfig
</pre>

A lot of configuration must be done to make the kernel work. To ease this use
[[Cross Install Gentoo kernel-config|kernel-config]] which will configure a running
kernel for the Pandora. It uses the name "pherkad" as computer name. Change
this to any name you like in the config file. Calling oldconfig might be
necessary if "kernel-config" is too old for the current gta04-kernel.

<pre>
cp ../kernel-config .config
make oldconfig
make menuconfig
</pre>

In "General setup/Local version" change "-pherkad" to any name you like. But
use "-" as prefix.

Build the kernel and the device tree "omap3-pandora-600mhz.dtb". Pandora users
with 1 GHz units can use "omap3-pandora-1ghz.dts". Use as much CPU cores as you
have for the compiling process.

<pre>
export CPUS="$(grep processor /proc/cpuinfo | wc -l)"
make -j$CPUS zImage
make -j$CPUS modules
make omap3-pandora-600mhz.dtb
</pre>

Convert the kernel into an image for the U-Boot loader. Use any name you
like for "Linux-pherkad".

<pre>
mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008000 -n \
'Linux-pherkad' -d arch/arm/boot/zImage arch/arm/boot/uImage
</pre>

Generate a "boot.scr" file which loads the kernel image and the correct device
tree.

Keep an eye to the bootargs. It uses the following commands:

* Start the systemd as init process: "init=/lib/systemd/systemd".
* Be quiet: "quiet". This can be removed while development.
* Show a splash screen: "splash". There is currently no splash screen, so this
* Use the root file system at: "root=/dev/mmcblk0p2". Take care to use the same partition as described below.
* Use Ext 4 root file system: "rootfstype=ext4".
* Wait for root file system: "rootwait".
* Mount initially read only: "ro". systemd will remount it later as RW.
* Use the following SWAP partition for hibernation/resume: "resume=/dev/mmcblk0p3". This is currently not used.

The file "boot.txt" will be converted to the boot script "boot.src".

<pre>
cat >boot.txt <<EOF
if itest.w *0x4830a204 == 0x102f
then
setenv devicetree omap3-pandora-1ghz
else
setenv devicetree omap3-pandora-600mhz
fi
setenv defaultdisplay lcd
setenv bootargs "init=/lib/systemd/systemd quiet splash \
root=/dev/mmcblk0p2 rootfstype=ext4 rootwait ro resume=/dev/mmcblk0p3"
ext2load mmc 0:1 0x825f0000 /boot/\${devicetree}.dtb
ext2load mmc 0:1 0x80300000 /boot/uImage-pherkad
bootm 0x80300000 - 0x825f0000
EOF

mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n 'Boot script' \
-d boot.txt boot.scr
</pre>

Exit the kernel build environment.

<pre>
exit
</pre>

=== Install kernel ===

The installation of the kernel into the target directory must be done as root.
Create the "boot" directory for the kernel, device tree and boot script and
copy them to the target directory.

<pre>
su
umask 0022
cp arch/arm/boot/uImage /usr/$CROSSDEV_TARGET/boot/uImage-pherkad
cp .config /usr/$CROSSDEV_TARGET/boot/config-pherkad
cp System.map /usr/$CROSSDEV_TARGET/boot/System.map-pherkad
cp arch/arm/boot/dts/omap3-pandora-600mhz.dtb /usr/$CROSSDEV_TARGET/boot/.
cp boot.scr /usr/$CROSSDEV_TARGET/boot/.
</pre>

Create a link for the boot directory. This is used if the boot directory is an
own partition and the boot loader wants to load the kernel from "boot/uImage-*".
In our case it is not really necessary.

<pre>
(cd /usr/$CROSSDEV_TARGET/boot; ln -s . boot)
</pre>

Install all kernel modules into "target/lib/modules". The symbolic link is for
the cross compiling process to find the kernel configuration.

<pre>
make ARCH=arm CROSS_COMPILE=${CROSSDEV_TARGET}- \
INSTALL_MOD_PATH=/usr/$CROSSDEV_TARGET modules_install

(DIR="$PWD"; cd /usr/$CROSSDEV_TARGET/usr/src; ln -s $DIR linux)
cd ..
</pre>

== Compile system ==

Now it's time to cross compile the whole Gentoo system. The base system is
already installed in the "target" directory. All the binaries there will
be compiled again with our own cross compiler. Also a lot of new packages
(more binaries) will be installed.

=== Prepare cross development system ===

Go to the target and copy all portage configurations from the desktop computer
to the target system, since we want to use the desktop computer system as
base of the Pandora system. This must be done as root.

<pre>
export FROM_DIR="$PWD"
cd /usr/$CROSSDEV_TARGET
</pre>

Edit the "make.conf" file.

<pre>
nano etc/portage/make.conf
</pre>

Change some of the lines there. You might copy some of the contents from
the desktop computer but be sure to have the same CHOST as the CROSSDEV_TARGET.
Especially add or change for the following:

<pre>
CFLAGS="-O2 -pipe -march=armv7-a -mfpu=vfpv3-d16 -mfloat-abi=softfp \
-mfpu=neon -fno-stack-protector"
</pre>

or

<pre>
CFLAGS="-O2 -pipe -march=armv7-a -mfpu=vfpv3-d16 -mfloat-abi=hard \
-mfpu=neon -fno-stack-protector"
</pre>

<pre>

GENTOO_MIRRORS="<enter your mirrors>"
PKGDIR="/usr/portage/packages/${CHOST}"
</pre>

It is recommended to activate the build of binary packages. The cross
compilation will fail to build some packages, so QEmu will build all packages
again. It is not necessary to build good cross compiled packages by QEmu again.
Using binary packages will avoid this and save a lot of time.

To avoid mixing up the binary packages of the desktop comuter and the Pandora
set PKGDIR accordingly. Example: "/usr/portage/packages/${CHOST}"

Also copy and edit some package specific files from your desktop computer.

<pre>
cp -r /etc/portage/package.* etc/portage/.
</pre>

Edit the files in "etc/portage/package.*" and configure the portage tree.

<pre>
sed -i "s/amd64/arm/g" etc/portage/package.keywords/*
rm -r etc/portage/package.keywords/cross*
rm -r etc/portage/package.mask/cross*
rm etc/portage/package.use/cross*
rm etc/portage/package.env/cross*

mkdir etc/portage/repos.conf
cp usr/share/portage/config/repos.conf etc/portage/repos.conf/gentoo.conf
rm -f etc/portage/make.profile

(cd etc/portage && \
ln -s /usr/portage/profiles/default/linux/arm/13.0/armv7a/desktop make.profile)
</pre>

Copy the world file from the desktop computer and remove all packages which
should not be installed on the Pandora system.

<pre>
cp /var/lib/portage/world var/lib/portage/world
nano var/lib/portage/world
</pre>

=== Prepare cross-compilation and QEmu environment ===

A lot of packages will fail but we will keep going the emerge process and
compile the failed packages again with QEmu.

But first update the compiler tools in the target system. They will be needed
later in the QEmu environment. If they fail here, try to do it in the QEmu
part.

Copy the static QEmu binary to the target system and set up portage for the
target system.

<pre>
cp /usr/bin/qemu-arm usr/bin/.
mkdir -p usr/portage
touch usr/portage/.keep
</pre>

Do some standard setup for the target system. Copy some personal configurations
to the root account.

<pre>
cp -L /etc/resolv.conf etc/.
cp -r etc/skel/. root/.

cp /root/.bashrc /root/.dir_colors /root/.screenrc /root/.toprc \
/root/.xsession root/.
</pre>

Some nice tools like htop are worth to install them on the Pandora.

<pre>
mkdir -m0700 root/.config
cp -r /root/.config/htop root/.config/.
</pre>

To access the root account with ssh, copy its configuration. This copies the
"id_*" files, also. Don't do this if you deliberately take care about security.

<pre>
cp -r /root/.ssh/. root/.ssh/.
</pre>

=== Start cross compilation ===

Set up a cross compilation environment (use a third shell instance).

<pre>
bash
export CBUILD=x86_64-pc-linux-gnu
export CHOST=$CROSSDEV_TARGET
export ROOT=$PWD
export PORTAGE_CONFIGROOT=$ROOT
export PS1="($CHOST) $PS1"
</pre>

Try to cross compile all packages.

<pre>
$CHOST-emerge -a binutils glibc linux-headers gcc
$CHOST-emerge -ae @world
</pre>

If one of them fails, save the resume list.

<pre>
$CHOST-emerge -p --resume | grep "^\[[eb].*\]" | grep -ve "^\[blocks" | \
cut -b 18- | cut -d " " -f1 | awk '{ print("=" $0); }' >tmp/packages.txt
</pre>

Now go to "Continue cross-compilation with QEmu".

=== Continue cross-compilation with QEmu ===

Enter the chroot environment and emerge the failed package again (the first one
in the packages.txt file).

The portage tree will be mounted into the target system.

In the chroot environment it might be necessary to switch the compiler. Check
if the same version of gcc is used than the cross compiler with
"gcc-config -l". Set the correct version before starting "emerge".

<pre>
mkdir -p $PWD/run/systemd/resolve
cp /run/systemd/resolve/resolv.conf $PWD/run/systemd/resolve/.
mount --rbind /proc $PWD/proc
mount --make-rslave $PWD/proc
mount --rbind /sys $PWD/sys
mount --make-rslave $PWD/sys
mount --rbind /dev $PWD/dev
mount --make-rslave $PWD/dev
mount --rbind /usr/portage $PWD/usr/portage
chroot $PWD /bin/bash
unset CBUILD CHOST ROOT PORTAGE_CONFIGROOT
env-update
source /etc/profile
cd
source ./.bashrc
export PS1="(chroot) $PS1"
emerge -aB1 $(head -1 /tmp/packages.txt)
exit
umount -l usr/portage
umount -l dev sys proc
</pre>

After fixing the failed package(s), continue with the cross compiler.

<pre>
cat tmp/packages.txt | xargs $CHOST-emerge -1
</pre>

If one of them fails again, save the resume list.

<pre>
$CHOST-emerge -p --resume | grep "^\[[eb].*\]" | grep -ve "^\[blocks" | \
cut -b 18- | cut -d " " -f1 | awk '{ print("=" $0); }' >tmp/packages.txt
</pre>

*Go back to "Continue cross-compilation with QEmu" until all packages are merged
successfully.*

Remove some leftover temporary files.

<pre>
rm -rf /var/tmp/portage/* /usr/$CROSSDEV_TARGET/var/tmp/portage/* \
/usr/$CROSSDEV_TARGET/tmp/packages.txt
</pre>

== Fix lib64-problem ==

Some cross compiled packages install their libraries into the "lib64" directory.
This is not used on the Pandora. So we have to copy all contents from "lib64"
to "lib" and set a link for "lib64".

<pre>
rsync -avc usr/lib64/. usr/lib/.
rm -rf usr/lib64
(cd usr && ln -s lib lib64)
</pre>

== Configure system ==

Set the key map for Pandora in the console and, as usual in Gentoo,
configure the target system.

Use to make the Pandora keyboard work on the console.
[[File:Keymap-pandora.map|thumbnail|keymap-pandora.map]]

<pre>
cp "$FROM_DIR/keymap-pandora.map" etc/.
chmod 644 etc/keymap-pandora.map
echo >etc/vconsole.conf "KEYMAP=/etc/keymap-pandora.map"
echo >>etc/vconsole.conf "FONT=eurlatgr"
</pre>

Set up the mount table. Every line in "etc/fstab" will be commented out and
new entries added. The file system labels are used to mount the partitions.

<pre>
sed -ie "s,^/,#/,g" etc/fstab

cat >>etc/fstab <<EOF
LABEL=phlnx_boot /boot ext2 noauto,noatime 1 2
LABEL=phlnx_root / ext4 errors=remount-ro,noatime 1 1
LABEL=phlnx_home /home ext4 noauto,noatime,nodev,nosuid 1 2
EOF
</pre>

Enter the chroot environment again.

<pre>
mount --rbind /proc $PWD/proc
mount --make-rslave $PWD/proc
mount --rbind /sys $PWD/sys
mount --make-rslave $PWD/sys
mount --rbind /dev $PWD/dev
mount --make-rslave $PWD/dev
mount --rbind /usr/portage $PWD/usr/portage
chroot $PWD /bin/bash
unset CBUILD CHOST ROOT PORTAGE_CONFIGROOT
env-update
source /etc/profile
cd
source ./.bashrc
export PS1="(chroot) $PS1"
</pre>

Set a password for root.

<pre>
passwd
</pre>

Update the configuration files and read/clear all news from portage.

<pre>
dispatch-conf
eselect news list
eselect news read
eselect news purge
</pre>

Enter the time zone and generate the locale info you want (example: enable all
lines with en_US and de_DE).

<pre>
echo "Europe/Berlin" >/etc/timezone
emerge --config sys-libs/timezone-data
nano -w /etc/locale.gen
locale-gen
</pre>

Use en_US.utf8 (entry #9) as locale.

<pre>
eselect locale list
eselect locale set 9
</pre>

Set up mount table, the machine ID and host name.

<pre>
ln -sf /proc/self/mounts /etc/mtab
systemd-machine-id-setup
echo >/etc/machine-info "PRETTY_HOSTNAME=Pherkad"
echo >/etc/hostname "pherkad"
ln -snf /run/systemd/resolve/resolv.conf /etc/resolv.conf
systemctl enable systemd-resolved.service
</pre>

Exit the chroot environment.

<pre>
exit
umount -l usr/portage
umount -l dev sys proc
</pre>

Remove the QEmu binary. It is not used anymore.

<pre>
rm usr/bin/qemu-arm
</pre>

Also remove some leftovers from the cross compiler and the link to our kernel
sources.

<pre>
rm -f etc/portage/profile/package.provided
rm -f sys-include
rm -f usr/src/linux
</pre>

Copy back the target system and restore the previous cross compiler state.

<pre>
cd "$FROM_DIR"
mkdir $CROSSDEV_TARGET
rsync -a /usr/$CROSSDEV_TARGET/. $CROSSDEV_TARGET/.
rm -rf /usr/$CROSSDEV_TARGET
tar -xpjf ${CROSSDEV_TARGET}-saved.tar.bz2 -C /usr
rm ${CROSSDEV_TARGET}-saved.tar.bz2
</pre>

Exit the root shell.

<pre>
exit
</pre>

= Update system =

To update the system, use a similar approach as in the cross compilation phase.
Define CROSSDEV_TARGET as in "Install cross compiling system".

== Start cross-compilation ==

Set up a cross compilation environment (become root and use a second shell
instance again).

<pre>
cd CrossDev
su
umask 0022

If the cross build system is no more used, it can be removed by the following
commands.

<pre>
su
crossdev --clean $CROSSDEV_TARGET
rm -rf /usr/portage/packages/x86_64-pc-linux-gnu/cross-$CROSSDEV_TARGET
emaint --fix binhost
emaint --fix world
rm -rf /usr/local/portage-crossdev
rm -rf /usr/libexec/gcc/$CROSSDEV_TARGET
rm -rf /usr/bin/${CROSSDEV_TARGET}*
rm -f /etc/portage/repos.conf/crossdev.conf
rm -f /etc/portage/categories
emerge --depclean crossdev
rm /usr/bin/repositories_configuration-*
exit
</pre>

= Create SD-card partitions phlnx_boot/root/swap/home =

Finally the target system is done. Now it's time to copy it to the Pandora.

== Pandora ==

It's recommended to partition the SD-card for the target system on the Pandora.
Otherwise the boot loader might refuse to work.

Insert the SD-card in the left slot (mmcblk0) and unmount it if necessary.

Create the following partitions:

* A boot partition (ext2).
* A root partition which will contain the target system (at least 4 GB).
* A home partition which we can use later.
* A SWAP partition which we can use later.

<pre>
sudo -s

/sbin/fdisk /dev/mmcblk0
Create new DOS partition label: o
Create new partition: n p 1 Return +8M
Create new partition: n p 2 Return +4G
Create new partition: n p 3 Return +1G
Change partition type: t 3 82 (Linux swap)
Create new partition: n p Return Return
Write all changes: w

/sbin/mkfs.ext2 -FL phlnx_boot /dev/mmcblk0p1
/sbin/mkfs.ext4 -FL phlnx_root -O ^has_journal /dev/mmcblk0p2
/sbin/mkswap -L phlnx_swap /dev/mmcblk0p3
/sbin/mkfs.ext4 -FL phlnx_home -O ^has_journal /dev/mmcblk0p4
exit
</pre>

= Option #1: Copy target system to SD-card =

One of the possibilities to copy the target system to the SD-card on the Pandora
is to use a USB cable connecting the Pandora to the desktop computer.

It's also possible to copy it via the WiFi network (see below).

== Pandora ==

Connect the Pandora via USB to the desktop computer. Insert the SD-card in the
left slot (mmcblk0). Use menu "System/SD-Mass Storage" to access partition
"phlnx_root".

== Desktop computer ==

Mount the root partition and copy the target system. Use the correct "/dev/sd*".

<pre>
su
mkdir /tmp/mnt
mount /dev/sdc /tmp/mnt
mkdir -p /tmp/mnt/boot
touch /tmp/mnt/boot/.keep
mkdir -p /tmp/mnt/home
touch /tmp/mnt/home/.keep

rsync -av --delete --exclude lost+found --exclude /boot \
CrossDev/$CROSSDEV_TARGET/. /tmp/mnt/.

umount /tmp/mnt
</pre>

== Pandora ==

Use "System/SD-Mass Storage" again to access phlnx_boot.

== Desktop computer ==

Mount the boot partition and copy boot directory of the target system.

<pre>
mount /dev/sdc /tmp/mnt
rm -f /tmp/mnt/uImage-pherkad

rsync -av --delete --exclude lost+found \
CrossDev/$CROSSDEV_TARGET/boot/. /tmp/mnt/.

umount /tmp/mnt
rmdir /tmp/mnt
exit
</pre>

== Pandora ==

End SD-Mass Storage.

= Option #2: Copy target system to SD-card via WiFi network =

== Pandora ==

Copy all files from the desktop computer to the SD-card partitions. Use the
same CROSSDEV_TARGET and FROM_DIR environment settings as on the desktop
computer.

<pre>
sudo -s
export REMOTE=mizar.spdns.de
export FROM_DIR=/home/jgeiss/Data/Systems/Pandora/Pherkad/Linux/Gentoo/CrossDev
export CROSSDEV_TARGET=armv7a-hardfloat-linux-gnueabi

mkdir -p /media/phlnx_root/boot
touch /media/phlnx_root/boot/.keep

rsync -av --numeric-ids --delete --exclude lost+found --exclude /boot \
$REMOTE:$FROM_DIR/$CROSSDEV_TARGET/. /media/phlnx_root/.

rsync -av --delete --exclude lost+found \
$REMOTE:$FROM_DIR/$CROSSDEV_TARGET/boot/. /media/phlnx_boot/.

exit
</pre>

= Boot the new system =

Reboot the Pandora and hold the right shoulder button until the boot menu
appears.

'''Sometimes it is necessary to switch off the Pandora for 10-60 seconds.'''

Choose "boot from SD1:1".

It the boot works well, login as root and play around.

== Optional: USB-networking ==

To use networking to the desktop computer via USB cable, execute the
following commands on both systems.

=== Pandora ===

<pre>
modprobe g_ether
ifconfig usb0 192.168.129.3 netmask 255.255.255.0
route add default gw 192.168.129.2
systemctl start sshd
</pre>

=== Desktop computer ===

Configure the corresponding network interface.

<pre>
ifconfig enp0s20u1u1 192.168.129.2 netmask 255.255.255.0
</pre>

Now you should be able to connect to the Pandora.

<pre>
ssh root@192.168.129.3
</pre>

== Shutdown Pandora ==

To shutdown the Pandora system enter the following command.

<pre>
systemctl poweroff
</pre>

= Open issues =

The following things are currently not working and need to be implemented/fixed:

* wl1251 board initialization failed
* tw1: not initialized
* omapfb omapfb: no displays, failed to setup omapfb
* omap2_set_init_voltage: unable to find boot up OPP vor ...
* __nand_correct_data: uncorrectable ECC error
* Buffer I/O error on dev mtdblock0, logical block 0, async page read
* Cursor and other GPIO-related keys do not work correctly if CPU is idle. Workaround: echo 1 >/sys/devices/system/cpu/cpu0/cpuidle/state4/disable
* Kernel panic at system shutdown
* fstab: Auto-Mounting /boot or /home causes system suspend after about 30 Seconds.

Cross Install Gentoo

2018-06-05T06:32:38Z

Jgeiss: Case of file corrected

= Cross install Gentoo Linux on Pandora =

== Introduction ==

These instructions are for installing a recent Gentoo Linux on the OpenPandora
handheld console. The system will be installed and booted from a SD-card. The
Gentoo Linux will be cross-compiled on another desktop computer also running
Gentoo Linux.

It is not necessary to follow all instructions exactly. Some of them can be
changed to your own needs.

'''The system currently supports only the text console and no X11 or sound.'''
'''Also a lot of features are missing.''' See "Open issues" at the end.

=== Prerequisites ===

These instructions assume the following prerequisites:

* Good knowledge in Gentoo Linux.
* A desktop computer running Gentoo Linux. Other Linux is, of course, also possible but requires proper adaption of these instructions.
* An OpenPandora handheld console.
* A SD-card with least 8 GB size.
* A USB cable to connect the Pandora to the desktop computer.

=== Improvement ===

Due to the constant changes of the Linux kernel, GNU software, etc. this
document will be outdated very quick. To avoid this, help is always appreciated
improving this document. If you can update, improve, add or complete this
document, don't hesitate to do so.

== Prepare/install cross compile system ==

To perform the cross-compilation a cross compiler and QEmu must be installed
on the desktop computer. QEmu will help a lot for compiling packages which
will not properly cross compile.

=== Install cross compiling system ===

For compiling software for an ARM controller a cross compiler must be installed.

We can use ARMv7 using either soft float (armv7a-softfp-linux-gnueabi) or hard
float (armv7a-hardfloat-linux-gnueabi).

<pre>export CROSSDEV_TARGET=armv7a-softfp-linux-gnueabi</pre>

or

<pre>export CROSSDEV_TARGET=armv7a-hardfloat-linux-gnueabi</pre>

The additional portage tree in "/usr/local/portage-crossdev" will hold all
information for emerging the cross build system (cross compiler and tools).

To prepare emerging a cross compiler, execute the following commands.

<pre>
su
umask 0022

emerge -av crossdev

mkdir -p /usr/local/portage-crossdev/{profiles,metadata}

echo 'local-crossdev' >/usr/local/portage-crossdev/profiles/repo_name
echo 'masters = gentoo' >/usr/local/portage-crossdev/metadata/layout.conf
echo 'thin-manifests = true' >>/usr/local/portage-crossdev/metadata/layout.conf
chown -R portage:portage /usr/local/portage-crossdev

echo '[local-crossdev]' >/etc/portage/repos.conf/crossdev.conf

echo 'location = /usr/local/portage-crossdev' \
>>/etc/portage/repos.conf/crossdev.conf

echo 'priority = 10' >>/etc/portage/repos.conf/crossdev.conf
echo 'masters = gentoo' >>/etc/portage/repos.conf/crossdev.conf
echo 'auto-sync = no' >>/etc/portage/repos.conf/crossdev.conf
</pre>

The portage tree for emerging the cross build system is set up. Now we have to
find out which versions of the cross build components are about to be installed.
The target system will get binutils, gcc, glibc and linux-headers of a certain
version. The same version should be installed in the cross build system.

<pre>
export BINUTILS_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-devel/binutils/binutils-*.ebuild | tail -1 | \
awk 'match($0, ".*/binutils-(.*).ebuild", v) { print(v[1]); }')

export GCC_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-devel/gcc/gcc-*.ebuild | tail -1 | \
awk 'match($0, ".*/gcc-(.*).ebuild", v) { print(v[1]); }')

export GLIBC_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-libs/glibc/glibc-*.ebuild | tail -1 | \
awk 'match($0, ".*/glibc-(.*).ebuild", v) { print(v[1]); }')

export LINUX_HEADERS_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-kernel/linux-headers/linux-headers-*.ebuild | tail -1 | \
awk 'match($0, ".*/linux-headers-(.*).ebuild", v) { print(v[1]); }')
</pre>

Now emerge the cross compiler.

<pre>
crossdev --binutils $BINUTILS_VER --gcc $GCC_VER --libc $GLIBC_VER \
--kernel $LINUX_HEADERS_VER --target $CROSSDEV_TARGET
</pre>

=== Install QEmu ===

A lot of packages will not cross compile properly. QEmu will help for these
packages. Install it to emulate an ARM controller.

Edit /etc/portage/make.conf.

<pre>
nano /etc/portage/make.conf
</pre>

And add the following lines.

<pre>
QEMU_SOFTMMU_TARGETS=""
QEMU_USER_TARGETS="arm"
</pre>

Also enable the use flag static-user. This builds QEmu as static binary.
QEmu will be used later in a chroot environment of an ARM controller and will
be unable to access needed shared libraries. So it must contain all these
libraries by building it in a static way.

<pre>
euse -E static-user
</pre>

All the needed libraries for QEmu must also be available as library archive
(static libs). Emerging QEmu will request to emerge these libraries as
static variants, also. Create and add these libraries in the file
"/etc/portage/package.use/qemu". Look which libraries are needed.

<pre>
emerge -pv qemu
</pre>

And add them with the use flag static-libs. Here is an Example:

<pre>
>=net-misc/curl-7.53.0 static-libs
>=sys-apps/attr-2.4.47-r2 static-libs
>=media-libs/libsdl-1.2.15-r9 static-libs
>=sys-apps/dtc-1.4.1 static-libs
>=app-arch/bzip2-1.0.6-r7 static-libs
>=x11-libs/pixman-0.34.0 static-libs
>=dev-libs/libpcre-8.40-r1 static-libs
>=sys-libs/libseccomp-2.3.0 static-libs
>=net-fs/libnfs-1.9.7 static-libs
>=dev-libs/cyrus-sasl-2.1.26-r9 static-libs
>=dev-libs/gmp-6.1.0 static-libs
>=dev-libs/libaio-0.3.110 static-libs
>=sys-fs/xfsprogs-4.5.0 static-libs
>=sys-libs/zlib-1.2.11 static-libs
>=media-libs/libjpeg-turbo-1.5.0 static-libs
>=sys-libs/libcap-ng-0.7.8 static-libs
>=dev-libs/openssl-1.0.2k static-libs
>=dev-libs/glib-2.50.3-r1 static-libs
>=virtual/jpeg-0-r2:0 static-libs
>=media-libs/libpng-1.6.27 static-libs
>=sys-libs/ncurses-6.0-r1 static-libs
</pre>

Emerge QEmu.

<pre>
emerge qemu
udevadm trigger -c add /dev/kvm
</pre>

QEmu will execute ARM binaries on the desktop computer as if it would have an
ARM controller. To achieve this, register foreign binaries and start the
systemd service.

<pre>
ln -s /usr/share/qemu/binfmt.d/qemu.conf /etc/binfmt.d/qemu.conf
systemctl start systemd-binfmt
</pre>

Now our desktop computer is able to execute ARM binaries as well as his own
binaries.

=== Install GIT ===

To get the kernel sources, GIT will be needed. Emerge it.

<pre>
emerge git
</pre>

Exit the root shell.

<pre>
exit
</pre>

Now the cross build system is ready to compile a Gentoo Linux for the Pandora.

== Prepare target file system ==

To build the system for the Pandora about 10 GB disk space is needed. Create a
directory "CrossDev" to store all data there.

<pre>
mkdir CrossDev
cd CrossDev
</pre>

In this directory two more directories will be created:

* One to store and build the Linux kernel.
* Another will store the whole system for the Pandora including QEmu which is not really a part of the system for Pandora, but it is needed as long as the building process runs.
* Some files and archives.

First get the Gentoo base system "stage3-armv7a-*.tar.bz2". Download it from
a suitable mirror of the Gentoo distribution. See
https://www.gentoo.org/downloads/mirrors for a list of mirrors.

Go to the directory "releases/arm/autobuilds". According to your target, enter

* "current-stage3-armv7a" for soft float (armv7a-softfp-linux-gnueabi),
* "current-stage3-armv7a_hardfp" for hard float (armv7a-hardfloat-linux-gnueabi).

There is a stage 3 file for ARMv7. Download this archive.

Example:

<pre>
wget http://mirror.eu.oneandone.net/linux/distributions/gentoo/gentoo/\
releases/arm/autobuilds/current-stage3-armv7a/stage3-armv7a-20161129.tar.bz2
</pre>

or

<pre>
wget http://mirror.eu.oneandone.net/linux/distributions/gentoo/gentoo/\
releases/arm/autobuilds/current-stage3-armv7a_hardfp/\
stage3-armv7a_hardfp-20161129.tar.bz2
</pre>

As long as we are cross compiling, we use "/usr/$CROSSDEV_TARGET" as working
directory. The cross compiler looks for libraries there and uses many references
to this directory. That's why "/usr/$CROSSDEV_TARGET" will be saved, so it can
be restored after the build.

<pre>
su
umask 0022
tar -cpjf ${CROSSDEV_TARGET}-saved.tar.bz2 -C /usr $CROSSDEV_TARGET
</pre>

Unpack the stage 3 archive into "/usr/$CROSSDEV_TARGET".

<pre>
tar --xattrs --numeric-owner -xpjf stage3-*.tar.bz2 -C /usr/$CROSSDEV_TARGET
</pre>

Sometimes there is a lot of garbage in the "tmp" directory. Remove it.

<pre>
rm -rf /usr/$CROSSDEV_TARGET/tmp/*
</pre>

Exit the root shell and go back to our working directory.

<pre>
exit
</pre>

== Compile/install kernel ==

The standard Gentoo kernel will not run on the Pandora (or, at least, takes too
much effort to make it run), so download a current kernel from
https://goldelico.com using GIT.

=== Download kernel ===

Download the kernel with GIT.

<pre>
git clone git://git.goldelico.com/gta04-kernel.git
cd gta04-kernel
</pre>

=== Compile kernel ===

Prepare an environment to cross compile the kernel. First call another shell
instance for saving the current environment. This instance is not really
necessary but it is more convenient because the saved environment is restored
after exiting the new shell.

<pre>
bash
umask 0022
export ARCH=arm CROSS_COMPILE=${CROSSDEV_TARGET}-
export PS1="($ARCH) $PS1"
</pre>

The kernel does not support the blue symbols on the keys used by "Fn". To enable
this, patch the kernel using the patch file kernel-patch-Fn-keys.txt.
[[File:kernel-patch-Fn-keys.txt|thumbnail|kernel-patch-Fn-keys.txt]]

<pre>
patch -p1 <../kernel-patch-Fn-keys.txt
</pre>

This patches the files "arch/arm/boot/dts/omap3-pandora-common.dtsi" which will
get more key codes for the blue symbols and
"drivers/input/keyboard/twl4030_keypad.c" which will handle the keys.

Now a default configuration for the kernel will be created.

<pre>
make omap2plus_defconfig
</pre>

A lot of configuration must be done to make the kernel work. To ease this use
kernel-config which will configure a running
kernel for the Pandora. It uses the name "pherkad" as computer name. Change
this to any name you like in the config file. Calling oldconfig might be
necessary if "kernel-config" is too old for the current gta04-kernel.
[[File:Kernel-config|thumbnail|kernel-config]]

<pre>
cp ../kernel-config .config
make oldconfig
make menuconfig
</pre>

In "General setup/Local version" change "-pherkad" to any name you like. But
use "-" as prefix.

Build the kernel and the device tree "omap3-pandora-600mhz.dtb". Pandora users
with 1 GHz units can use "omap3-pandora-1ghz.dts". Use as much CPU cores as you
have for the compiling process.

<pre>
export CPUS="$(grep processor /proc/cpuinfo | wc -l)"
make -j$CPUS zImage
make -j$CPUS modules
make omap3-pandora-600mhz.dtb
</pre>

Convert the kernel into an image for the U-Boot loader. Use any name you
like for "Linux-pherkad".

<pre>
mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008000 -n \
'Linux-pherkad' -d arch/arm/boot/zImage arch/arm/boot/uImage
</pre>

Generate a "boot.scr" file which loads the kernel image and the correct device
tree.

Keep an eye to the bootargs. It uses the following commands:

* Start the systemd as init process: "init=/lib/systemd/systemd".
* Be quiet: "quiet". This can be removed while development.
* Show a splash screen: "splash". There is currently no splash screen, so this
* Use the root file system at: "root=/dev/mmcblk0p2". Take care to use the same partition as described below.
* Use Ext 4 root file system: "rootfstype=ext4".
* Wait for root file system: "rootwait".
* Mount initially read only: "ro". systemd will remount it later as RW.
* Use the following SWAP partition for hibernation/resume: "resume=/dev/mmcblk0p3". This is currently not used.

The file "boot.txt" will be converted to the boot script "boot.src".

<pre>
cat >boot.txt <<EOF
if itest.w *0x4830a204 == 0x102f
then
setenv devicetree omap3-pandora-1ghz
else
setenv devicetree omap3-pandora-600mhz
fi
setenv defaultdisplay lcd
setenv bootargs "init=/lib/systemd/systemd quiet splash \
root=/dev/mmcblk0p2 rootfstype=ext4 rootwait ro resume=/dev/mmcblk0p3"
ext2load mmc 0:1 0x825f0000 /boot/\${devicetree}.dtb
ext2load mmc 0:1 0x80300000 /boot/uImage-pherkad
bootm 0x80300000 - 0x825f0000
EOF

mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n 'Boot script' \
-d boot.txt boot.scr
</pre>

Exit the kernel build environment.

<pre>
exit
</pre>

=== Install kernel ===

The installation of the kernel into the target directory must be done as root.
Create the "boot" directory for the kernel, device tree and boot script and
copy them to the target directory.

<pre>
su
umask 0022
cp arch/arm/boot/uImage /usr/$CROSSDEV_TARGET/boot/uImage-pherkad
cp .config /usr/$CROSSDEV_TARGET/boot/config-pherkad
cp System.map /usr/$CROSSDEV_TARGET/boot/System.map-pherkad
cp arch/arm/boot/dts/omap3-pandora-600mhz.dtb /usr/$CROSSDEV_TARGET/boot/.
cp boot.scr /usr/$CROSSDEV_TARGET/boot/.
</pre>

Create a link for the boot directory. This is used if the boot directory is an
own partition and the boot loader wants to load the kernel from "boot/uImage-*".
In our case it is not really necessary.

<pre>
(cd /usr/$CROSSDEV_TARGET/boot; ln -s . boot)
</pre>

Install all kernel modules into "target/lib/modules". The symbolic link is for
the cross compiling process to find the kernel configuration.

<pre>
make ARCH=arm CROSS_COMPILE=${CROSSDEV_TARGET}- \
INSTALL_MOD_PATH=/usr/$CROSSDEV_TARGET modules_install

(DIR="$PWD"; cd /usr/$CROSSDEV_TARGET/usr/src; ln -s $DIR linux)
cd ..
</pre>

== Compile system ==

Now it's time to cross compile the whole Gentoo system. The base system is
already installed in the "target" directory. All the binaries there will
be compiled again with our own cross compiler. Also a lot of new packages
(more binaries) will be installed.

=== Prepare cross development system ===

Go to the target and copy all portage configurations from the desktop computer
to the target system, since we want to use the desktop computer system as
base of the Pandora system. This must be done as root.

<pre>
export FROM_DIR="$PWD"
cd /usr/$CROSSDEV_TARGET
</pre>

Edit the "make.conf" file.

<pre>
nano etc/portage/make.conf
</pre>

Change some of the lines there. You might copy some of the contents from
the desktop computer but be sure to have the same CHOST as the CROSSDEV_TARGET.
Especially add or change for the following:

<pre>
CFLAGS="-O2 -pipe -march=armv7-a -mfpu=vfpv3-d16 -mfloat-abi=softfp \
-mfpu=neon -fno-stack-protector"
</pre>

or

<pre>
CFLAGS="-O2 -pipe -march=armv7-a -mfpu=vfpv3-d16 -mfloat-abi=hard \
-mfpu=neon -fno-stack-protector"
</pre>

GENTOO_MIRRORS="<enter your mirrors>"
PKGDIR="/usr/portage/packages/${CHOST}"
</pre>

It is recommended to activate the build of binary packages. The cross
compilation will fail to build some packages, so QEmu will build all packages
again. It is not necessary to build good cross compiled packages by QEmu again.
Using binary packages will avoid this and save a lot of time.

To avoid mixing up the binary packages of the desktop comuter and the Pandora
set PKGDIR accordingly. Example: "/usr/portage/packages/${CHOST}"

Also copy and edit some package specific files from your desktop computer.

<pre>
cp -r /etc/portage/package.* etc/portage/.
</pre>

Edit the files in "etc/portage/package.*" and configure the portage tree.

<pre>
sed -i "s/amd64/arm/g" etc/portage/package.keywords/*
rm -r etc/portage/package.keywords/cross*
rm -r etc/portage/package.mask/cross*
rm etc/portage/package.use/cross*
rm etc/portage/package.env/cross*

mkdir etc/portage/repos.conf
cp usr/share/portage/config/repos.conf etc/portage/repos.conf/gentoo.conf
rm -f etc/portage/make.profile

(cd etc/portage && \
ln -s /usr/portage/profiles/default/linux/arm/13.0/armv7a/desktop make.profile)
</pre>

Copy the world file from the desktop computer and remove all packages which
should not be installed on the Pandora system.

<pre>
cp /var/lib/portage/world var/lib/portage/world
nano var/lib/portage/world
</pre>

=== Prepare cross-compilation and QEmu environment ===

A lot of packages will fail but we will keep going the emerge process and
compile the failed packages again with QEmu.

But first update the compiler tools in the target system. They will be needed
later in the QEmu environment. If they fail here, try to do it in the QEmu
part.

Copy the static QEmu binary to the target system and set up portage for the
target system.

<pre>
cp /usr/bin/qemu-arm usr/bin/.
mkdir -p usr/portage
touch usr/portage/.keep
</pre>

Do some standard setup for the target system. Copy some personal configurations
to the root account.

<pre>
cp -L /etc/resolv.conf etc/.
cp -r etc/skel/. root/.

cp /root/.bashrc /root/.dir_colors /root/.screenrc /root/.toprc \
/root/.xsession root/.
</pre>

Some nice tools like htop are worth to install them on the Pandora.

<pre>
mkdir -m0700 root/.config
cp -r /root/.config/htop root/.config/.
</pre>

To access the root account with ssh, copy its configuration. This copies the
"id_*" files, also. Don't do this if you deliberately take care about security.

<pre>
cp -r /root/.ssh/. root/.ssh/.
</pre>

=== Start cross compilation ===

Set up a cross compilation environment (use a third shell instance).

<pre>
bash
export CBUILD=x86_64-pc-linux-gnu
export CHOST=$CROSSDEV_TARGET
export ROOT=$PWD
export PORTAGE_CONFIGROOT=$ROOT
export PS1="($CHOST) $PS1"
</pre>

Try to cross compile all packages.

<pre>
$CHOST-emerge -a binutils glibc linux-headers gcc
$CHOST-emerge -ae @world
</pre>

If one of them fails, save the resume list.

<pre>
$CHOST-emerge -p --resume | grep "^\[[eb].*\]" | grep -ve "^\[blocks" | \
cut -b 18- | cut -d " " -f1 | awk '{ print("=" $0); }' >tmp/packages.txt
</pre>

Now go to "Continue cross-compilation with QEmu".

=== Continue cross-compilation with QEmu ===

Enter the chroot environment and emerge the failed package again (the first one
in the packages.txt file).

The portage tree will be mounted into the target system.

In the chroot environment it might be necessary to switch the compiler. Check
if the same version of gcc is used than the cross compiler with
"gcc-config -l". Set the correct version before starting "emerge".

<pre>
mkdir -p $PWD/run/systemd/resolve
cp /run/systemd/resolve/resolv.conf $PWD/run/systemd/resolve/.

source ./.bashrc
export PS1="(chroot) $PS1"
emerge -aB1 $(head -1 /tmp/packages.txt)
exit
umount -l usr/portage
umount -l dev sys proc
</pre>

After fixing the failed package(s), continue with the cross compiler.

<pre>
cat tmp/packages.txt | xargs $CHOST-emerge -1
</pre>

If one of them fails again, save the resume list.

<pre>
$CHOST-emerge -p --resume | grep "^\[[eb].*\]" | grep -ve "^\[blocks" | \
cut -b 18- | cut -d " " -f1 | awk '{ print("=" $0); }' >tmp/packages.txt
</pre>

*Go back to "Continue cross-compilation with QEmu" until all packages are merged
successfully.*

Remove some leftover temporary files.

<pre>
rm -rf /var/tmp/portage/* /usr/$CROSSDEV_TARGET/var/tmp/portage/* \
/usr/$CROSSDEV_TARGET/tmp/packages.txt
</pre>

== Fix lib64-problem ==

Some cross compiled packages install their libraries into the "lib64" directory.
This is not used on the Pandora. So we have to copy all contents from "lib64"
to "lib" and set a link for "lib64".

<pre>
rsync -avc usr/lib64/. usr/lib/.
rm -rf usr/lib64
(cd usr && ln -s lib lib64)
</pre>

== Configure system ==

Set the key map for Pandora in the console and, as usual in Gentoo,
configure the target system.

Use to make the Pandora keyboard work on the console.
[[File:Keymap-pandora.map|thumbnail|keymap-pandora.map]]

<pre>
cp "$FROM_DIR/keymap-pandora.map" etc/.
chmod 644 etc/keymap-pandora.map
echo >etc/vconsole.conf "KEYMAP=/etc/keymap-pandora.map"
echo >>etc/vconsole.conf "FONT=eurlatgr"
</pre>

Set up the mount table. Every line in "etc/fstab" will be commented out and
new entries added. The file system labels are used to mount the partitions.

<pre>
sed -ie "s,^/,#/,g" etc/fstab

cat >>etc/fstab <<EOF
LABEL=phlnx_boot /boot ext2 noauto,noatime 1 2
LABEL=phlnx_root / ext4 errors=remount-ro,noatime 1 1
LABEL=phlnx_home /home ext4 noauto,noatime,nodev,nosuid 1 2
EOF
</pre>

Enter the chroot environment again.

<pre>
mount --rbind /proc $PWD/proc
mount --make-rslave $PWD/proc
mount --rbind /sys $PWD/sys
mount --make-rslave $PWD/sys
mount --rbind /dev $PWD/dev

</pre>

Update the configuration files and read/clear all news from portage.

<pre>
dispatch-conf
eselect news list
eselect news read
eselect news purge
</pre>

Enter the time zone and generate the locale info you want (example: enable all
lines with en_US and de_DE).

<pre>
echo "Europe/Berlin" >/etc/timezone
emerge --config sys-libs/timezone-data
nano -w /etc/locale.gen
locale-gen
</pre>

Use en_US.utf8 (entry #9) as locale.

<pre>
eselect locale list
eselect locale set 9
</pre>

Set up mount table, the machine ID and host name.

<pre>
ln -sf /proc/self/mounts /etc/mtab
systemd-machine-id-setup
echo >/etc/machine-info "PRETTY_HOSTNAME=Pherkad"
echo >/etc/hostname "pherkad"
ln -snf /run/systemd/resolve/resolv.conf /etc/resolv.conf
systemctl enable systemd-resolved.service
</pre>

Exit the chroot environment.

<pre>
exit
umount -l usr/portage
umount -l dev sys proc
</pre>

Remove the QEmu binary. It is not used anymore.

<pre>
rm usr/bin/qemu-arm
</pre>

Also remove some leftovers from the cross compiler and the link to our kernel
sources.

<pre>
rm -f etc/portage/profile/package.provided
rm -f sys-include
rm -f usr/src/linux
</pre>

Copy back the target system and restore the previous cross compiler state.

<pre>

rm ${CROSSDEV_TARGET}-saved.tar.bz2
</pre>

Exit the root shell.

<pre>
exit
</pre>

= Update system =

To update the system, use a similar approach as in the cross compilation phase.
Define CROSSDEV_TARGET as in "Install cross compiling system".

== Start cross-compilation ==

Set up a cross compilation environment (become root and use a second shell
instance again).

<pre>

= Create SD-card partitions phlnx_boot/root/swap/home =

Finally the target system is done. Now it's time to copy it to the Pandora.

== Pandora ==

It's recommended to partition the SD-card for the target system on the Pandora.
Otherwise the boot loader might refuse to work.

Insert the SD-card in the left slot (mmcblk0) and unmount it if necessary.

Create the following partitions:

* A boot partition (ext2).
* A root partition which will contain the target system (at least 4 GB).
* A home partition which we can use later.
* A SWAP partition which we can use later.

<pre>
sudo -s

/sbin/fdisk /dev/mmcblk0
Create new DOS partition label: o
Create new partition: n p 1 Return +8M
Create new partition: n p 2 Return +4G
Create new partition: n p 3 Return +1G
Change partition type: t 3 82 (Linux swap)
Create new partition: n p Return Return
Write all changes: w

/sbin/mkfs.ext2 -FL phlnx_boot /dev/mmcblk0p1
/sbin/mkfs.ext4 -FL phlnx_root -O ^has_journal /dev/mmcblk0p2
/sbin/mkswap -L phlnx_swap /dev/mmcblk0p3
/sbin/mkfs.ext4 -FL phlnx_home -O ^has_journal /dev/mmcblk0p4
exit
</pre>

= Option #1: Copy target system to SD-card =

One of the possibilities to copy the target system to the SD-card on the Pandora
is to use a USB cable connecting the Pandora to the desktop computer.

It's also possible to copy it via the WiFi network (see below).

== Pandora ==

Connect the Pandora via USB to the desktop computer. Insert the SD-card in the
left slot (mmcblk0). Use menu "System/SD-Mass Storage" to access partition
"phlnx_root".

== Desktop computer ==

Mount the root partition and copy the target system. Use the correct "/dev/sd*".

<pre>
su
mkdir /tmp/mnt
mount /dev/sdc /tmp/mnt
mkdir -p /tmp/mnt/boot
touch /tmp/mnt/boot/.keep
mkdir -p /tmp/mnt/home
touch /tmp/mnt/home/.keep

rsync -av --delete --exclude lost+found --exclude /boot \
CrossDev/$CROSSDEV_TARGET/. /tmp/mnt/.

umount /tmp/mnt
</pre>

== Pandora ==

Use "System/SD-Mass Storage" again to access phlnx_boot.

== Desktop computer ==

Mount the boot partition and copy boot directory of the target system.

<pre>
mount /dev/sdc /tmp/mnt
rm -f /tmp/mnt/uImage-pherkad

rsync -av --delete --exclude lost+found \
CrossDev/$CROSSDEV_TARGET/boot/. /tmp/mnt/.

umount /tmp/mnt
rmdir /tmp/mnt
exit
</pre>

== Pandora ==

End SD-Mass Storage.

= Option #2: Copy target system to SD-card via WiFi network =

== Pandora ==

Copy all files from the desktop computer to the SD-card partitions. Use the
same CROSSDEV_TARGET and FROM_DIR environment settings as on the desktop
computer.

<pre>
sudo -s
export REMOTE=mizar.spdns.de
export FROM_DIR=/home/jgeiss/Data/Systems/Pandora/Pherkad/Linux/Gentoo/CrossDev
export CROSSDEV_TARGET=armv7a-hardfloat-linux-gnueabi

mkdir -p /media/phlnx_root/boot
touch /media/phlnx_root/boot/.keep

rsync -av --numeric-ids --delete --exclude lost+found --exclude /boot \
$REMOTE:$FROM_DIR/$CROSSDEV_TARGET/. /media/phlnx_root/.

rsync -av --delete --exclude lost+found \
$REMOTE:$FROM_DIR/$CROSSDEV_TARGET/boot/. /media/phlnx_boot/.

exit
</pre>

= Boot the new system =

Reboot the Pandora and hold the right shoulder button until the boot menu
appears.

'''Sometimes it is necessary to switch off the Pandora for 10-60 seconds.'''

Choose "boot from SD1:1".

It the boot works well, login as root and play around.

== Optional: USB-networking ==

To use networking to the desktop computer via USB cable, execute the
following commands on both systems.

=== Pandora ===

<pre>
modprobe g_ether
ifconfig usb0 192.168.129.3 netmask 255.255.255.0
route add default gw 192.168.129.2
systemctl start sshd
</pre>

=== Desktop computer ===

Configure the corresponding network interface.

<pre>
ifconfig enp0s20u1u1 192.168.129.2 netmask 255.255.255.0
</pre>

Now you should be able to connect to the Pandora.

<pre>
ssh root@192.168.129.3
</pre>

== Shutdown Pandora ==

To shutdown the Pandora system enter the following command.

<pre>
systemctl poweroff
</pre>

= Open issues =

The following things are currently not working and need to be implemented/fixed:

* wl1251 board initialization failed
* tw1: not initialized
* omapfb omapfb: no displays, failed to setup omapfb
* omap2_set_init_voltage: unable to find boot up OPP vor ...
* __nand_correct_data: uncorrectable ECC error
* Buffer I/O error on dev mtdblock0, logical block 0, async page read
* Cursor and other GPIO-related keys do not work correctly if CPU is idle. Workaround: echo 1 >/sys/devices/system/cpu/cpu0/cpuidle/state4/disable
* Kernel panic at system shutdown
* fstab: Auto-Mounting /boot or /home causes system suspend after about 30 Seconds.

Cross Install Gentoo

2018-06-04T19:10:50Z

Jgeiss: Section indentation corrected

= Cross install Gentoo Linux on Pandora =

== Introduction ==

These instructions are for installing a recent Gentoo Linux on the OpenPandora
handheld console. The system will be installed and booted from a SD-card. The
Gentoo Linux will be cross-compiled on another desktop computer also running
Gentoo Linux.

It is not necessary to follow all instructions exactly. Some of them can be
changed to your own needs.

'''The system currently supports only the text console and no X11 or sound.'''
'''Also a lot of features are missing.''' See "Open issues" at the end.

=== Prerequisites ===

These instructions assume the following prerequisites:

* Good knowledge in Gentoo Linux.
* A desktop computer running Gentoo Linux. Other Linux is, of course, also possible but requires proper adaption of these instructions.
* An OpenPandora handheld console.
* A SD-card with least 8 GB size.
* A USB cable to connect the Pandora to the desktop computer.

=== Improvement ===

Due to the constant changes of the Linux kernel, GNU software, etc. this
document will be outdated very quick. To avoid this, help is always appreciated
improving this document. If you can update, improve, add or complete this
document, don't hesitate to do so.

== Prepare/install cross compile system ==

To perform the cross-compilation a cross compiler and QEmu must be installed
on the desktop computer. QEmu will help a lot for compiling packages which
will not properly cross compile.

=== Install cross compiling system ===

For compiling software for an ARM controller a cross compiler must be installed.

We can use ARMv7 using either soft float (armv7a-softfp-linux-gnueabi) or hard
float (armv7a-hardfloat-linux-gnueabi).

<pre>export CROSSDEV_TARGET=armv7a-softfp-linux-gnueabi</pre>

or

<pre>export CROSSDEV_TARGET=armv7a-hardfloat-linux-gnueabi</pre>

The additional portage tree in "/usr/local/portage-crossdev" will hold all
information for emerging the cross build system (cross compiler and tools).

To prepare emerging a cross compiler, execute the following commands.

<pre>
su
umask 0022

emerge -av crossdev

mkdir -p /usr/local/portage-crossdev/{profiles,metadata}

echo 'local-crossdev' >/usr/local/portage-crossdev/profiles/repo_name
echo 'masters = gentoo' >/usr/local/portage-crossdev/metadata/layout.conf
echo 'thin-manifests = true' >>/usr/local/portage-crossdev/metadata/layout.conf
chown -R portage:portage /usr/local/portage-crossdev

echo '[local-crossdev]' >/etc/portage/repos.conf/crossdev.conf

echo 'location = /usr/local/portage-crossdev' \
>>/etc/portage/repos.conf/crossdev.conf

echo 'priority = 10' >>/etc/portage/repos.conf/crossdev.conf
echo 'masters = gentoo' >>/etc/portage/repos.conf/crossdev.conf
echo 'auto-sync = no' >>/etc/portage/repos.conf/crossdev.conf
</pre>

The portage tree for emerging the cross build system is set up. Now we have to
find out which versions of the cross build components are about to be installed.
The target system will get binutils, gcc, glibc and linux-headers of a certain
version. The same version should be installed in the cross build system.

<pre>
export BINUTILS_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-devel/binutils/binutils-*.ebuild | tail -1 | \
awk 'match($0, ".*/binutils-(.*).ebuild", v) { print(v[1]); }')

export GCC_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-devel/gcc/gcc-*.ebuild | tail -1 | \
awk 'match($0, ".*/gcc-(.*).ebuild", v) { print(v[1]); }')

export GLIBC_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-libs/glibc/glibc-*.ebuild | tail -1 | \
awk 'match($0, ".*/glibc-(.*).ebuild", v) { print(v[1]); }')

export LINUX_HEADERS_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-kernel/linux-headers/linux-headers-*.ebuild | tail -1 | \
awk 'match($0, ".*/linux-headers-(.*).ebuild", v) { print(v[1]); }')
</pre>

Now emerge the cross compiler.

<pre>
crossdev --binutils $BINUTILS_VER --gcc $GCC_VER --libc $GLIBC_VER \
--kernel $LINUX_HEADERS_VER --target $CROSSDEV_TARGET
</pre>

=== Install QEmu ===

A lot of packages will not cross compile properly. QEmu will help for these
packages. Install it to emulate an ARM controller.

Edit /etc/portage/make.conf.

<pre>
nano /etc/portage/make.conf
</pre>

And add the following lines.

<pre>
QEMU_SOFTMMU_TARGETS=""
QEMU_USER_TARGETS="arm"
</pre>

Also enable the use flag static-user. This builds QEmu as static binary.
QEmu will be used later in a chroot environment of an ARM controller and will
be unable to access needed shared libraries. So it must contain all these
libraries by building it in a static way.

<pre>
euse -E static-user
</pre>

All the needed libraries for QEmu must also be available as library archive
(static libs). Emerging QEmu will request to emerge these libraries as
static variants, also. Create and add these libraries in the file
"/etc/portage/package.use/qemu". Look which libraries are needed.

<pre>
emerge -pv qemu
</pre>

And add them with the use flag static-libs. Here is an Example:

<pre>
>=net-misc/curl-7.53.0 static-libs
>=sys-apps/attr-2.4.47-r2 static-libs
>=media-libs/libsdl-1.2.15-r9 static-libs
>=sys-apps/dtc-1.4.1 static-libs
>=app-arch/bzip2-1.0.6-r7 static-libs
>=x11-libs/pixman-0.34.0 static-libs
>=dev-libs/libpcre-8.40-r1 static-libs
>=sys-libs/libseccomp-2.3.0 static-libs
>=net-fs/libnfs-1.9.7 static-libs
>=dev-libs/cyrus-sasl-2.1.26-r9 static-libs
>=dev-libs/gmp-6.1.0 static-libs
>=dev-libs/libaio-0.3.110 static-libs
>=sys-fs/xfsprogs-4.5.0 static-libs
>=sys-libs/zlib-1.2.11 static-libs
>=media-libs/libjpeg-turbo-1.5.0 static-libs
>=sys-libs/libcap-ng-0.7.8 static-libs
>=dev-libs/openssl-1.0.2k static-libs
>=dev-libs/glib-2.50.3-r1 static-libs
>=virtual/jpeg-0-r2:0 static-libs
>=media-libs/libpng-1.6.27 static-libs
>=sys-libs/ncurses-6.0-r1 static-libs
</pre>

Emerge QEmu.

<pre>
emerge qemu
udevadm trigger -c add /dev/kvm
</pre>

QEmu will execute ARM binaries on the desktop computer as if it would have an
ARM controller. To achieve this, register foreign binaries and start the
systemd service.

<pre>
ln -s /usr/share/qemu/binfmt.d/qemu.conf /etc/binfmt.d/qemu.conf
systemctl start systemd-binfmt
</pre>

Now our desktop computer is able to execute ARM binaries as well as his own
binaries.

=== Install GIT ===

To get the kernel sources, GIT will be needed. Emerge it.

<pre>
emerge git
</pre>

Exit the root shell.

<pre>
exit
</pre>

Now the cross build system is ready to compile a Gentoo Linux for the Pandora.

== Prepare target file system ==

To build the system for the Pandora about 10 GB disk space is needed. Create a
directory "CrossDev" to store all data there.

<pre>
mkdir CrossDev
cd CrossDev
</pre>

In this directory two more directories will be created:

* One to store and build the Linux kernel.
* Another will store the whole system for the Pandora including QEmu which is not really a part of the system for Pandora, but it is needed as long as the building process runs.
* Some files and archives.

First get the Gentoo base system "stage3-armv7a-*.tar.bz2". Download it from
a suitable mirror of the Gentoo distribution. See
https://www.gentoo.org/downloads/mirrors for a list of mirrors.

Go to the directory "releases/arm/autobuilds". According to your target, enter

* "current-stage3-armv7a" for soft float (armv7a-softfp-linux-gnueabi),
* "current-stage3-armv7a_hardfp" for hard float (armv7a-hardfloat-linux-gnueabi).

There is a stage 3 file for ARMv7. Download this archive.

Example:

<pre>
wget http://mirror.eu.oneandone.net/linux/distributions/gentoo/gentoo/\
releases/arm/autobuilds/current-stage3-armv7a/stage3-armv7a-20161129.tar.bz2
</pre>

or

<pre>
wget http://mirror.eu.oneandone.net/linux/distributions/gentoo/gentoo/\
releases/arm/autobuilds/current-stage3-armv7a_hardfp/\
stage3-armv7a_hardfp-20161129.tar.bz2
</pre>

As long as we are cross compiling, we use "/usr/$CROSSDEV_TARGET" as working
directory. The cross compiler looks for libraries there and uses many references
to this directory. That's why "/usr/$CROSSDEV_TARGET" will be saved, so it can
be restored after the build.

<pre>
su
umask 0022
tar -cpjf ${CROSSDEV_TARGET}-saved.tar.bz2 -C /usr $CROSSDEV_TARGET
</pre>

Unpack the stage 3 archive into "/usr/$CROSSDEV_TARGET".

<pre>
tar --xattrs --numeric-owner -xpjf stage3-*.tar.bz2 -C /usr/$CROSSDEV_TARGET
</pre>

Sometimes there is a lot of garbage in the "tmp" directory. Remove it.

<pre>
rm -rf /usr/$CROSSDEV_TARGET/tmp/*
</pre>

Exit the root shell and go back to our working directory.

<pre>
exit
</pre>

== Compile/install kernel ==

The standard Gentoo kernel will not run on the Pandora (or, at least, takes too
much effort to make it run), so download a current kernel from
https://goldelico.com using GIT.

=== Download kernel ===

Download the kernel with GIT.

<pre>
git clone git://git.goldelico.com/gta04-kernel.git
cd gta04-kernel
</pre>

=== Compile kernel ===

Prepare an environment to cross compile the kernel. First call another shell
instance for saving the current environment. This instance is not really
necessary but it is more convenient because the saved environment is restored
after exiting the new shell.

<pre>
bash
umask 0022
export ARCH=arm CROSS_COMPILE=${CROSSDEV_TARGET}-
export PS1="($ARCH) $PS1"
</pre>

The kernel does not support the blue symbols on the keys used by "Fn". To enable
this, patch the kernel using the patch file kernel-patch-Fn-keys.txt.
[[File:Kernel-patch-Fn-keys.txt|thumbnail|kernel-patch-Fn-keys.txt]]

<pre>
patch -p1 <../kernel-patch-Fn-keys.txt
</pre>

This patches the files "arch/arm/boot/dts/omap3-pandora-common.dtsi" which will
get more key codes for the blue symbols and
"drivers/input/keyboard/twl4030_keypad.c" which will handle the keys.

Now a default configuration for the kernel will be created.

<pre>
make omap2plus_defconfig
</pre>

A lot of configuration must be done to make the kernel work. To ease this use
kernel-config which will configure a running
kernel for the Pandora. It uses the name "pherkad" as computer name. Change
this to any name you like in the config file. Calling oldconfig might be
necessary if "kernel-config" is too old for the current gta04-kernel.
[[File:Kernel-config|thumbnail|kernel-config]]

<pre>
cp ../kernel-config .config
make oldconfig
make menuconfig
</pre>

In "General setup/Local version" change "-pherkad" to any name you like. But
use "-" as prefix.

Build the kernel and the device tree "omap3-pandora-600mhz.dtb". Pandora users
with 1 GHz units can use "omap3-pandora-1ghz.dts". Use as much CPU cores as you
have for the compiling process.

<pre>
export CPUS="$(grep processor /proc/cpuinfo | wc -l)"
make -j$CPUS zImage
make -j$CPUS modules
make omap3-pandora-600mhz.dtb
</pre>

Convert the kernel into an image for the U-Boot loader. Use any name you
like for "Linux-pherkad".

<pre>
mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008000 -n \
'Linux-pherkad' -d arch/arm/boot/zImage arch/arm/boot/uImage
</pre>

Generate a "boot.scr" file which loads the kernel image and the correct device
tree.

Keep an eye to the bootargs. It uses the following commands:

* Start the systemd as init process: "init=/lib/systemd/systemd".
* Be quiet: "quiet". This can be removed while development.
* Show a splash screen: "splash". There is currently no splash screen, so this
* Use the root file system at: "root=/dev/mmcblk0p2". Take care to use the same partition as described below.
* Use Ext 4 root file system: "rootfstype=ext4".
* Wait for root file system: "rootwait".
* Mount initially read only: "ro". systemd will remount it later as RW.
* Use the following SWAP partition for hibernation/resume: "resume=/dev/mmcblk0p3". This is currently not used.

The file "boot.txt" will be converted to the boot script "boot.src".

<pre>
cat >boot.txt <<EOF
if itest.w *0x4830a204 == 0x102f
then
setenv devicetree omap3-pandora-1ghz
else
setenv devicetree omap3-pandora-600mhz
fi
setenv defaultdisplay lcd
setenv bootargs "init=/lib/systemd/systemd quiet splash \
root=/dev/mmcblk0p2 rootfstype=ext4 rootwait ro resume=/dev/mmcblk0p3"
ext2load mmc 0:1 0x825f0000 /boot/\${devicetree}.dtb
ext2load mmc 0:1 0x80300000 /boot/uImage-pherkad
bootm 0x80300000 - 0x825f0000
EOF

mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n 'Boot script' \
-d boot.txt boot.scr
</pre>

Exit the kernel build environment.

<pre>
exit
</pre>

=== Install kernel ===

The installation of the kernel into the target directory must be done as root.
Create the "boot" directory for the kernel, device tree and boot script and
copy them to the target directory.

<pre>
su
umask 0022
cp arch/arm/boot/uImage /usr/$CROSSDEV_TARGET/boot/uImage-pherkad
cp .config /usr/$CROSSDEV_TARGET/boot/config-pherkad
cp System.map /usr/$CROSSDEV_TARGET/boot/System.map-pherkad
cp arch/arm/boot/dts/omap3-pandora-600mhz.dtb /usr/$CROSSDEV_TARGET/boot/.
cp boot.scr /usr/$CROSSDEV_TARGET/boot/.
</pre>

Create a link for the boot directory. This is used if the boot directory is an
own partition and the boot loader wants to load the kernel from "boot/uImage-*".
In our case it is not really necessary.

<pre>
(cd /usr/$CROSSDEV_TARGET/boot; ln -s . boot)
</pre>

Install all kernel modules into "target/lib/modules". The symbolic link is for
the cross compiling process to find the kernel configuration.

<pre>
make ARCH=arm CROSS_COMPILE=${CROSSDEV_TARGET}- \
INSTALL_MOD_PATH=/usr/$CROSSDEV_TARGET modules_install

(DIR="$PWD"; cd /usr/$CROSSDEV_TARGET/usr/src; ln -s $DIR linux)
cd ..
</pre>

== Compile system ==

Now it's time to cross compile the whole Gentoo system. The base system is
already installed in the "target" directory. All the binaries there will
be compiled again with our own cross compiler. Also a lot of new packages
(more binaries) will be installed.

=== Prepare cross development system ===

Go to the target and copy all portage configurations from the desktop computer
to the target system, since we want to use the desktop computer system as
base of the Pandora system. This must be done as root.

<pre>
export FROM_DIR="$PWD"
cd /usr/$CROSSDEV_TARGET
</pre>

Edit the "make.conf" file.

<pre>
nano etc/portage/make.conf
</pre>

Change some of the lines there. You might copy some of the contents from
the desktop computer but be sure to have the same CHOST as the CROSSDEV_TARGET.
Especially add or change for the following:

<pre>
CFLAGS="-O2 -pipe -march=armv7-a -mfpu=vfpv3-d16 -mfloat-abi=softfp \
-mfpu=neon -fno-stack-protector"
</pre>

or

<pre>
CFLAGS="-O2 -pipe -march=armv7-a -mfpu=vfpv3-d16 -mfloat-abi=hard \
-mfpu=neon -fno-stack-protector"
</pre>

GENTOO_MIRRORS="<enter your mirrors>"
PKGDIR="/usr/portage/packages/${CHOST}"
</pre>

It is recommended to activate the build of binary packages. The cross
compilation will fail to build some packages, so QEmu will build all packages
again. It is not necessary to build good cross compiled packages by QEmu again.
Using binary packages will avoid this and save a lot of time.

To avoid mixing up the binary packages of the desktop comuter and the Pandora
set PKGDIR accordingly. Example: "/usr/portage/packages/${CHOST}"

Also copy and edit some package specific files from your desktop computer.

<pre>
cp -r /etc/portage/package.* etc/portage/.
</pre>

Edit the files in "etc/portage/package.*" and configure the portage tree.

<pre>
sed -i "s/amd64/arm/g" etc/portage/package.keywords/*
rm -r etc/portage/package.keywords/cross*
rm -r etc/portage/package.mask/cross*
rm etc/portage/package.use/cross*
rm etc/portage/package.env/cross*

mkdir etc/portage/repos.conf
cp usr/share/portage/config/repos.conf etc/portage/repos.conf/gentoo.conf
rm -f etc/portage/make.profile

(cd etc/portage && \
ln -s /usr/portage/profiles/default/linux/arm/13.0/armv7a/desktop make.profile)
</pre>

Copy the world file from the desktop computer and remove all packages which
should not be installed on the Pandora system.

<pre>
cp /var/lib/portage/world var/lib/portage/world
nano var/lib/portage/world
</pre>

=== Prepare cross-compilation and QEmu environment ===

A lot of packages will fail but we will keep going the emerge process and
compile the failed packages again with QEmu.

But first update the compiler tools in the target system. They will be needed
later in the QEmu environment. If they fail here, try to do it in the QEmu
part.

Copy the static QEmu binary to the target system and set up portage for the
target system.

<pre>
cp /usr/bin/qemu-arm usr/bin/.
mkdir -p usr/portage
touch usr/portage/.keep
</pre>

Do some standard setup for the target system. Copy some personal configurations
to the root account.

<pre>
cp -L /etc/resolv.conf etc/.
cp -r etc/skel/. root/.

cp /root/.bashrc /root/.dir_colors /root/.screenrc /root/.toprc \
/root/.xsession root/.
</pre>

Some nice tools like htop are worth to install them on the Pandora.

<pre>
mkdir -m0700 root/.config
cp -r /root/.config/htop root/.config/.
</pre>

To access the root account with ssh, copy its configuration. This copies the
"id_*" files, also. Don't do this if you deliberately take care about security.

<pre>
cp -r /root/.ssh/. root/.ssh/.
</pre>

=== Start cross compilation ===

Set up a cross compilation environment (use a third shell instance).

<pre>
bash
export CBUILD=x86_64-pc-linux-gnu
export CHOST=$CROSSDEV_TARGET
export ROOT=$PWD
export PORTAGE_CONFIGROOT=$ROOT
export PS1="($CHOST) $PS1"
</pre>

Try to cross compile all packages.

<pre>
$CHOST-emerge -a binutils glibc linux-headers gcc
$CHOST-emerge -ae @world
</pre>

If one of them fails, save the resume list.

<pre>
$CHOST-emerge -p --resume | grep "^\[[eb].*\]" | grep -ve "^\[blocks" | \
cut -b 18- | cut -d " " -f1 | awk '{ print("=" $0); }' >tmp/packages.txt
</pre>

Now go to "Continue cross-compilation with QEmu".

=== Continue cross-compilation with QEmu ===

Enter the chroot environment and emerge the failed package again (the first one
in the packages.txt file).

The portage tree will be mounted into the target system.

In the chroot environment it might be necessary to switch the compiler. Check
if the same version of gcc is used than the cross compiler with
"gcc-config -l". Set the correct version before starting "emerge".

<pre>
mkdir -p $PWD/run/systemd/resolve
cp /run/systemd/resolve/resolv.conf $PWD/run/systemd/resolve/.
mount --rbind /proc $PWD/proc
mount --make-rslave $PWD/proc
mount --rbind /sys $PWD/sys
mount --make-rslave $PWD/sys
mount --rbind /dev $PWD/dev
mount --make-rslave $PWD/dev
mount --rbind /usr/portage $PWD/usr/portage
chroot $PWD /bin/bash
unset CBUILD CHOST ROOT PORTAGE_CONFIGROOT
env-update
source /etc/profile
cd
source ./.bashrc
export PS1="(chroot) $PS1"
emerge -aB1 $(head -1 /tmp/packages.txt)
exit
umount -l usr/portage
umount -l dev sys proc
</pre>

After fixing the failed package(s), continue with the cross compiler.

<pre>
cat tmp/packages.txt | xargs $CHOST-emerge -1
</pre>

If one of them fails again, save the resume list.

<pre>
$CHOST-emerge -p --resume | grep "^\[[eb].*\]" | grep -ve "^\[blocks" | \
cut -b 18- | cut -d " " -f1 | awk '{ print("=" $0); }' >tmp/packages.txt
</pre>

*Go back to "Continue cross-compilation with QEmu" until all packages are merged
successfully.*

Remove some leftover temporary files.

<pre>
rm -rf /var/tmp/portage/* /usr/$CROSSDEV_TARGET/var/tmp/portage/* \
/usr/$CROSSDEV_TARGET/tmp/packages.txt
</pre>

== Fix lib64-problem ==

Some cross compiled packages install their libraries into the "lib64" directory.
This is not used on the Pandora. So we have to copy all contents from "lib64"
to "lib" and set a link for "lib64".

<pre>
rsync -avc usr/lib64/. usr/lib/.
rm -rf usr/lib64
(cd usr && ln -s lib lib64)
</pre>

== Configure system ==

Set the key map for Pandora in the console and, as usual in Gentoo,
configure the target system.

Use to make the Pandora keyboard work on the console.
[[File:Keymap-pandora.map|thumbnail|keymap-pandora.map]]

<pre>
cp "$FROM_DIR/keymap-pandora.map" etc/.
chmod 644 etc/keymap-pandora.map
echo >etc/vconsole.conf "KEYMAP=/etc/keymap-pandora.map"
echo >>etc/vconsole.conf "FONT=eurlatgr"
</pre>

Set up the mount table. Every line in "etc/fstab" will be commented out and
new entries added. The file system labels are used to mount the partitions.

<pre>
sed -ie "s,^/,#/,g" etc/fstab

cat >>etc/fstab <<EOF
LABEL=phlnx_boot /boot ext2 noauto,noatime 1 2
LABEL=phlnx_root / ext4 errors=remount-ro,noatime 1 1
LABEL=phlnx_home /home ext4 noauto,noatime,nodev,nosuid 1 2
EOF
</pre>

Enter the chroot environment again.

<pre>
mount --rbind /proc $PWD/proc
mount --make-rslave $PWD/proc
mount --rbind /sys $PWD/sys
mount --make-rslave $PWD/sys
mount --rbind /dev $PWD/dev

chroot $PWD /bin/bash
unset CBUILD CHOST ROOT PORTAGE_CONFIGROOT
env-update
source /etc/profile
cd
source ./.bashrc
export PS1="(chroot) $PS1"
</pre>

Set a password for root.

<pre>
passwd
</pre>

Update the configuration files and read/clear all news from portage.

<pre>
dispatch-conf
eselect news list
eselect news read
eselect news purge
</pre>

Enter the time zone and generate the locale info you want (example: enable all
lines with en_US and de_DE).

<pre>
echo "Europe/Berlin" >/etc/timezone
emerge --config sys-libs/timezone-data
nano -w /etc/locale.gen
locale-gen
</pre>

Use en_US.utf8 (entry #9) as locale.

<pre>
eselect locale list
eselect locale set 9
</pre>

Set up mount table, the machine ID and host name.

<pre>
ln -sf /proc/self/mounts /etc/mtab
systemd-machine-id-setup
echo >/etc/machine-info "PRETTY_HOSTNAME=Pherkad"
echo >/etc/hostname "pherkad"
ln -snf /run/systemd/resolve/resolv.conf /etc/resolv.conf
systemctl enable systemd-resolved.service
</pre>

Exit the chroot environment.

<pre>
exit
umount -l usr/portage
umount -l dev sys proc
</pre>

Remove the QEmu binary. It is not used anymore.

<pre>
rm usr/bin/qemu-arm
</pre>

Also remove some leftovers from the cross compiler and the link to our kernel
sources.

<pre>
rm -f etc/portage/profile/package.provided
rm -f sys-include
rm -f usr/src/linux
</pre>

Copy back the target system and restore the previous cross compiler state.

<pre>
cd "$FROM_DIR"

rm -rf /usr/$CROSSDEV_TARGET
tar -xpjf ${CROSSDEV_TARGET}-saved.tar.bz2 -C /usr
rm ${CROSSDEV_TARGET}-saved.tar.bz2
</pre>

Exit the root shell.

<pre>
exit
</pre>

= Update system =

To update the system, use a similar approach as in the cross compilation phase.
Define CROSSDEV_TARGET as in "Install cross compiling system".

== Start cross-compilation ==

Set up a cross compilation environment (become root and use a second shell
instance again).

<pre>
cd CrossDev

= Create SD-card partitions phlnx_boot/root/swap/home =

Finally the target system is done. Now it's time to copy it to the Pandora.

== Pandora ==

It's recommended to partition the SD-card for the target system on the Pandora.
Otherwise the boot loader might refuse to work.

Insert the SD-card in the left slot (mmcblk0) and unmount it if necessary.

Create the following partitions:

* A boot partition (ext2).
* A root partition which will contain the target system (at least 4 GB).
* A home partition which we can use later.
* A SWAP partition which we can use later.

= Option #1: Copy target system to SD-card =

One of the possibilities to copy the target system to the SD-card on the Pandora
is to use a USB cable connecting the Pandora to the desktop computer.

It's also possible to copy it via the WiFi network (see below).

== Pandora ==

Connect the Pandora via USB to the desktop computer. Insert the SD-card in the
left slot (mmcblk0). Use menu "System/SD-Mass Storage" to access partition
"phlnx_root".

== Desktop computer ==

Mount the root partition and copy the target system. Use the correct "/dev/sd*".

<pre>
su
mkdir /tmp/mnt
mount /dev/sdc /tmp/mnt
mkdir -p /tmp/mnt/boot
touch /tmp/mnt/boot/.keep
mkdir -p /tmp/mnt/home
touch /tmp/mnt/home/.keep

rsync -av --delete --exclude lost+found --exclude /boot \
CrossDev/$CROSSDEV_TARGET/. /tmp/mnt/.

umount /tmp/mnt
</pre>

== Pandora ==

Use "System/SD-Mass Storage" again to access phlnx_boot.

== Desktop computer ==

Mount the boot partition and copy boot directory of the target system.

<pre>
mount /dev/sdc /tmp/mnt
rm -f /tmp/mnt/uImage-pherkad

rsync -av --delete --exclude lost+found \
CrossDev/$CROSSDEV_TARGET/boot/. /tmp/mnt/.

umount /tmp/mnt
rmdir /tmp/mnt
exit
</pre>

== Pandora ==

End SD-Mass Storage.

= Option #2: Copy target system to SD-card via WiFi network =

== Pandora ==

Copy all files from the desktop computer to the SD-card partitions. Use the
same CROSSDEV_TARGET and FROM_DIR environment settings as on the desktop
computer.

<pre>
sudo -s
export REMOTE=mizar.spdns.de
export FROM_DIR=/home/jgeiss/Data/Systems/Pandora/Pherkad/Linux/Gentoo/CrossDev
export CROSSDEV_TARGET=armv7a-hardfloat-linux-gnueabi

mkdir -p /media/phlnx_root/boot
touch /media/phlnx_root/boot/.keep

rsync -av --numeric-ids --delete --exclude lost+found --exclude /boot \
$REMOTE:$FROM_DIR/$CROSSDEV_TARGET/. /media/phlnx_root/.

rsync -av --delete --exclude lost+found \
$REMOTE:$FROM_DIR/$CROSSDEV_TARGET/boot/. /media/phlnx_boot/.

exit
</pre>

= Boot the new system =

Reboot the Pandora and hold the right shoulder button until the boot menu
appears.

'''Sometimes it is necessary to switch off the Pandora for 10-60 seconds.'''

Choose "boot from SD1:1".

It the boot works well, login as root and play around.

== Optional: USB-networking ==

To use networking to the desktop computer via USB cable, execute the
following commands on both systems.

=== Pandora ===

<pre>
modprobe g_ether
ifconfig usb0 192.168.129.3 netmask 255.255.255.0
route add default gw 192.168.129.2
systemctl start sshd
</pre>

=== Desktop computer ===

Configure the corresponding network interface.

<pre>
ifconfig enp0s20u1u1 192.168.129.2 netmask 255.255.255.0
</pre>

Now you should be able to connect to the Pandora.

<pre>
ssh root@192.168.129.3
</pre>

== Shutdown Pandora ==

To shutdown the Pandora system enter the following command.

<pre>
systemctl poweroff
</pre>

= Open issues =

The following things are currently not working and need to be implemented/fixed:

* wl1251 board initialization failed
* tw1: not initialized
* omapfb omapfb: no displays, failed to setup omapfb
* omap2_set_init_voltage: unable to find boot up OPP vor ...
* __nand_correct_data: uncorrectable ECC error
* Buffer I/O error on dev mtdblock0, logical block 0, async page read
* Cursor and other GPIO-related keys do not work correctly if CPU is idle. Workaround: echo 1 >/sys/devices/system/cpu/cpu0/cpuidle/state4/disable
* Kernel panic at system shutdown
* fstab: Auto-Mounting /boot or /home causes system suspend after about 30 Seconds.

Cross Install Gentoo

2018-06-04T19:03:15Z

Jgeiss: First release of this description

= Cross install Gentoo Linux on Pandora =

== Introduction ==

These instructions are for installing a recent Gentoo Linux on the OpenPandora
handheld console. The system will be installed and booted from a SD-card. The
Gentoo Linux will be cross-compiled on another desktop computer also running
Gentoo Linux.

It is not necessary to follow all instructions exactly. Some of them can be
changed to your own needs.

'''The system currently supports only the text console and no X11 or sound.'''
'''Also a lot of features are missing.''' See "Open issues" at the end.

=== Prerequisites ===

These instructions assume the following prerequisites:

* Good knowledge in Gentoo Linux.
* A desktop computer running Gentoo Linux. Other Linux is, of course, also possible but requires proper adaption of these instructions.
* An OpenPandora handheld console.
* A SD-card with least 8 GB size.
* A USB cable to connect the Pandora to the desktop computer.

=== Improvement ===

Due to the constant changes of the Linux kernel, GNU software, etc. this
document will be outdated very quick. To avoid this, help is always appreciated
improving this document. If you can update, improve, add or complete this
document, don't hesitate to do so.

== Prepare/install cross compile system ==

To perform the cross-compilation a cross compiler and QEmu must be installed
on the desktop computer. QEmu will help a lot for compiling packages which
will not properly cross compile.

=== Install cross compiling system ===

For compiling software for an ARM controller a cross compiler must be installed.

We can use ARMv7 using either soft float (armv7a-softfp-linux-gnueabi) or hard
float (armv7a-hardfloat-linux-gnueabi).

<pre>export CROSSDEV_TARGET=armv7a-softfp-linux-gnueabi</pre>

or

<pre>export CROSSDEV_TARGET=armv7a-hardfloat-linux-gnueabi</pre>

The additional portage tree in "/usr/local/portage-crossdev" will hold all
information for emerging the cross build system (cross compiler and tools).

To prepare emerging a cross compiler, execute the following commands.

<pre>
su
umask 0022

emerge -av crossdev

mkdir -p /usr/local/portage-crossdev/{profiles,metadata}

echo 'local-crossdev' >/usr/local/portage-crossdev/profiles/repo_name
echo 'masters = gentoo' >/usr/local/portage-crossdev/metadata/layout.conf
echo 'thin-manifests = true' >>/usr/local/portage-crossdev/metadata/layout.conf
chown -R portage:portage /usr/local/portage-crossdev

echo '[local-crossdev]' >/etc/portage/repos.conf/crossdev.conf

echo 'location = /usr/local/portage-crossdev' \
>>/etc/portage/repos.conf/crossdev.conf

echo 'priority = 10' >>/etc/portage/repos.conf/crossdev.conf
echo 'masters = gentoo' >>/etc/portage/repos.conf/crossdev.conf
echo 'auto-sync = no' >>/etc/portage/repos.conf/crossdev.conf
</pre>

The portage tree for emerging the cross build system is set up. Now we have to
find out which versions of the cross build components are about to be installed.
The target system will get binutils, gcc, glibc and linux-headers of a certain
version. The same version should be installed in the cross build system.

<pre>
export BINUTILS_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-devel/binutils/binutils-*.ebuild | tail -1 | \
awk 'match($0, ".*/binutils-(.*).ebuild", v) { print(v[1]); }')

export GCC_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-devel/gcc/gcc-*.ebuild | tail -1 | \
awk 'match($0, ".*/gcc-(.*).ebuild", v) { print(v[1]); }')

export GLIBC_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-libs/glibc/glibc-*.ebuild | tail -1 | \
awk 'match($0, ".*/glibc-(.*).ebuild", v) { print(v[1]); }')

export LINUX_HEADERS_VER=$(grep -le 'KEYWORDS.* arm' \
/usr/portage/sys-kernel/linux-headers/linux-headers-*.ebuild | tail -1 | \
awk 'match($0, ".*/linux-headers-(.*).ebuild", v) { print(v[1]); }')
</pre>

Now emerge the cross compiler.

<pre>
crossdev --binutils $BINUTILS_VER --gcc $GCC_VER --libc $GLIBC_VER \
--kernel $LINUX_HEADERS_VER --target $CROSSDEV_TARGET
</pre>

=== Install QEmu ===

A lot of packages will not cross compile properly. QEmu will help for these
packages. Install it to emulate an ARM controller.

Edit /etc/portage/make.conf.

<pre>
nano /etc/portage/make.conf
</pre>

And add the following lines.

<pre>
QEMU_SOFTMMU_TARGETS=""
QEMU_USER_TARGETS="arm"
</pre>

Also enable the use flag static-user. This builds QEmu as static binary.
QEmu will be used later in a chroot environment of an ARM controller and will
be unable to access needed shared libraries. So it must contain all these
libraries by building it in a static way.

<pre>
euse -E static-user
</pre>

All the needed libraries for QEmu must also be available as library archive
(static libs). Emerging QEmu will request to emerge these libraries as
static variants, also. Create and add these libraries in the file
"/etc/portage/package.use/qemu". Look which libraries are needed.

<pre>
emerge -pv qemu
</pre>

And add them with the use flag static-libs. Here is an Example:

<pre>
>=net-misc/curl-7.53.0 static-libs
>=sys-apps/attr-2.4.47-r2 static-libs
>=media-libs/libsdl-1.2.15-r9 static-libs
>=sys-apps/dtc-1.4.1 static-libs
>=app-arch/bzip2-1.0.6-r7 static-libs
>=x11-libs/pixman-0.34.0 static-libs
>=dev-libs/libpcre-8.40-r1 static-libs
>=sys-libs/libseccomp-2.3.0 static-libs
>=net-fs/libnfs-1.9.7 static-libs
>=dev-libs/cyrus-sasl-2.1.26-r9 static-libs
>=dev-libs/gmp-6.1.0 static-libs
>=dev-libs/libaio-0.3.110 static-libs
>=sys-fs/xfsprogs-4.5.0 static-libs
>=sys-libs/zlib-1.2.11 static-libs
>=media-libs/libjpeg-turbo-1.5.0 static-libs
>=sys-libs/libcap-ng-0.7.8 static-libs
>=dev-libs/openssl-1.0.2k static-libs
>=dev-libs/glib-2.50.3-r1 static-libs
>=virtual/jpeg-0-r2:0 static-libs
>=media-libs/libpng-1.6.27 static-libs
>=sys-libs/ncurses-6.0-r1 static-libs
</pre>

Emerge QEmu.

<pre>
emerge qemu
udevadm trigger -c add /dev/kvm
</pre>

QEmu will execute ARM binaries on the desktop computer as if it would have an
ARM controller. To achieve this, register foreign binaries and start the
systemd service.

<pre>
ln -s /usr/share/qemu/binfmt.d/qemu.conf /etc/binfmt.d/qemu.conf
systemctl start systemd-binfmt
</pre>

Now our desktop computer is able to execute ARM binaries as well as his own
binaries.

=== Install GIT ===

To get the kernel sources, GIT will be needed. Emerge it.

<pre>
emerge git
</pre>

Exit the root shell.

<pre>
exit
</pre>

Now the cross build system is ready to compile a Gentoo Linux for the Pandora.

== Prepare target file system ==

To build the system for the Pandora about 10 GB disk space is needed. Create a
directory "CrossDev" to store all data there.

<pre>
mkdir CrossDev
cd CrossDev
</pre>

In this directory two more directories will be created:

* One to store and build the Linux kernel.
* Another will store the whole system for the Pandora including QEmu which is not really a part of the system for Pandora, but it is needed as long as the building process runs.
* Some files and archives.

First get the Gentoo base system "stage3-armv7a-*.tar.bz2". Download it from
a suitable mirror of the Gentoo distribution. See
https://www.gentoo.org/downloads/mirrors for a list of mirrors.

Go to the directory "releases/arm/autobuilds". According to your target, enter

* "current-stage3-armv7a" for soft float (armv7a-softfp-linux-gnueabi),
* "current-stage3-armv7a_hardfp" for hard float (armv7a-hardfloat-linux-gnueabi).

There is a stage 3 file for ARMv7. Download this archive.

Example:

<pre>
wget http://mirror.eu.oneandone.net/linux/distributions/gentoo/gentoo/\
releases/arm/autobuilds/current-stage3-armv7a/stage3-armv7a-20161129.tar.bz2
</pre>

or

<pre>
wget http://mirror.eu.oneandone.net/linux/distributions/gentoo/gentoo/\
releases/arm/autobuilds/current-stage3-armv7a_hardfp/\
stage3-armv7a_hardfp-20161129.tar.bz2
</pre>

As long as we are cross compiling, we use "/usr/$CROSSDEV_TARGET" as working
directory. The cross compiler looks for libraries there and uses many references
to this directory. That's why "/usr/$CROSSDEV_TARGET" will be saved, so it can
be restored after the build.

<pre>
su
umask 0022
tar -cpjf ${CROSSDEV_TARGET}-saved.tar.bz2 -C /usr $CROSSDEV_TARGET
</pre>

Unpack the stage 3 archive into "/usr/$CROSSDEV_TARGET".

<pre>
tar --xattrs --numeric-owner -xpjf stage3-*.tar.bz2 -C /usr/$CROSSDEV_TARGET
</pre>

Sometimes there is a lot of garbage in the "tmp" directory. Remove it.

<pre>
rm -rf /usr/$CROSSDEV_TARGET/tmp/*
</pre>

Exit the root shell and go back to our working directory.

<pre>
exit
</pre>

== Compile/install kernel ==

The standard Gentoo kernel will not run on the Pandora (or, at least, takes too
much effort to make it run), so download a current kernel from
https://goldelico.com using GIT.

=== Download kernel ===

Download the kernel with GIT.

<pre>
git clone git://git.goldelico.com/gta04-kernel.git
cd gta04-kernel
</pre>

=== Compile kernel ===

Prepare an environment to cross compile the kernel. First call another shell
instance for saving the current environment. This instance is not really
necessary but it is more convenient because the saved environment is restored
after exiting the new shell.

<pre>
bash
umask 0022
export ARCH=arm CROSS_COMPILE=${CROSSDEV_TARGET}-
export PS1="($ARCH) $PS1"
</pre>

The kernel does not support the blue symbols on the keys used by "Fn". To enable
this, patch the kernel using the patch file kernel-patch-Fn-keys.txt.
[[File:Kernel-patch-Fn-keys.txt|thumbnail|kernel-patch-Fn-keys.txt]]

<pre>
patch -p1 <../kernel-patch-Fn-keys.txt
</pre>

This patches the files "arch/arm/boot/dts/omap3-pandora-common.dtsi" which will
get more key codes for the blue symbols and
"drivers/input/keyboard/twl4030_keypad.c" which will handle the keys.

Now a default configuration for the kernel will be created.

<pre>
make omap2plus_defconfig
</pre>

A lot of configuration must be done to make the kernel work. To ease this use
kernel-config which will configure a running
kernel for the Pandora. It uses the name "pherkad" as computer name. Change
this to any name you like in the config file. Calling oldconfig might be
necessary if "kernel-config" is too old for the current gta04-kernel.
[[File:Kernel-config|thumbnail|kernel-config]]

<pre>
cp ../kernel-config .config
make oldconfig
make menuconfig
</pre>

In "General setup/Local version" change "-pherkad" to any name you like. But
use "-" as prefix.

Build the kernel and the device tree "omap3-pandora-600mhz.dtb". Pandora users
with 1 GHz units can use "omap3-pandora-1ghz.dts". Use as much CPU cores as you
have for the compiling process.

<pre>
export CPUS="$(grep processor /proc/cpuinfo | wc -l)"
make -j$CPUS zImage
make -j$CPUS modules
make omap3-pandora-600mhz.dtb
</pre>

Convert the kernel into an image for the U-Boot loader. Use any name you
like for "Linux-pherkad".

<pre>
mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008000 -n \
'Linux-pherkad' -d arch/arm/boot/zImage arch/arm/boot/uImage
</pre>

Generate a "boot.scr" file which loads the kernel image and the correct device
tree.

Keep an eye to the bootargs. It uses the following commands:

* Start the systemd as init process: "init=/lib/systemd/systemd".
* Be quiet: "quiet". This can be removed while development.
* Show a splash screen: "splash". There is currently no splash screen, so this
* Use the root file system at: "root=/dev/mmcblk0p2". Take care to use the same partition as described below.
* Use Ext 4 root file system: "rootfstype=ext4".
* Wait for root file system: "rootwait".
* Mount initially read only: "ro". systemd will remount it later as RW.
* Use the following SWAP partition for hibernation/resume: "resume=/dev/mmcblk0p3". This is currently not used.

The file "boot.txt" will be converted to the boot script "boot.src".

<pre>
cat >boot.txt <<EOF
if itest.w *0x4830a204 == 0x102f
then
setenv devicetree omap3-pandora-1ghz
else
setenv devicetree omap3-pandora-600mhz
fi
setenv defaultdisplay lcd
setenv bootargs "init=/lib/systemd/systemd quiet splash \
root=/dev/mmcblk0p2 rootfstype=ext4 rootwait ro resume=/dev/mmcblk0p3"
ext2load mmc 0:1 0x825f0000 /boot/\${devicetree}.dtb
ext2load mmc 0:1 0x80300000 /boot/uImage-pherkad
bootm 0x80300000 - 0x825f0000
EOF

mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n 'Boot script' \
-d boot.txt boot.scr
</pre>

Exit the kernel build environment.

<pre>
exit
</pre>

=== Install kernel ===

The installation of the kernel into the target directory must be done as root.
Create the "boot" directory for the kernel, device tree and boot script and
copy them to the target directory.

<pre>
su
umask 0022
cp arch/arm/boot/uImage /usr/$CROSSDEV_TARGET/boot/uImage-pherkad
cp .config /usr/$CROSSDEV_TARGET/boot/config-pherkad
cp System.map /usr/$CROSSDEV_TARGET/boot/System.map-pherkad
cp arch/arm/boot/dts/omap3-pandora-600mhz.dtb /usr/$CROSSDEV_TARGET/boot/.
cp boot.scr /usr/$CROSSDEV_TARGET/boot/.
</pre>

Create a link for the boot directory. This is used if the boot directory is an
own partition and the boot loader wants to load the kernel from "boot/uImage-*".
In our case it is not really necessary.

<pre>
(cd /usr/$CROSSDEV_TARGET/boot; ln -s . boot)
</pre>

Install all kernel modules into "target/lib/modules". The symbolic link is for
the cross compiling process to find the kernel configuration.

<pre>
make ARCH=arm CROSS_COMPILE=${CROSSDEV_TARGET}- \
INSTALL_MOD_PATH=/usr/$CROSSDEV_TARGET modules_install

(DIR="$PWD"; cd /usr/$CROSSDEV_TARGET/usr/src; ln -s $DIR linux)
cd ..
</pre>

== Compile system ==

Now it's time to cross compile the whole Gentoo system. The base system is
already installed in the "target" directory. All the binaries there will
be compiled again with our own cross compiler. Also a lot of new packages
(more binaries) will be installed.

=== Prepare cross development system ===

Go to the target and copy all portage configurations from the desktop computer
to the target system, since we want to use the desktop computer system as
base of the Pandora system. This must be done as root.

<pre>
export FROM_DIR="$PWD"
cd /usr/$CROSSDEV_TARGET
</pre>

Edit the "make.conf" file.

<pre>
nano etc/portage/make.conf
</pre>

Change some of the lines there. You might copy some of the contents from
the desktop computer but be sure to have the same CHOST as the CROSSDEV_TARGET.
Especially add or change for the following:

<pre>
CFLAGS="-O2 -pipe -march=armv7-a -mfpu=vfpv3-d16 -mfloat-abi=softfp \
-mfpu=neon -fno-stack-protector"
</pre>

or

<pre>
CFLAGS="-O2 -pipe -march=armv7-a -mfpu=vfpv3-d16 -mfloat-abi=hard \
-mfpu=neon -fno-stack-protector"
</pre>

GENTOO_MIRRORS="<enter your mirrors>"
PKGDIR="/usr/portage/packages/${CHOST}"
</pre>

It is recommended to activate the build of binary packages. The cross
compilation will fail to build some packages, so QEmu will build all packages
again. It is not necessary to build good cross compiled packages by QEmu again.
Using binary packages will avoid this and save a lot of time.

To avoid mixing up the binary packages of the desktop comuter and the Pandora
set PKGDIR accordingly. Example: "/usr/portage/packages/${CHOST}"

Also copy and edit some package specific files from your desktop computer.

<pre>
cp -r /etc/portage/package.* etc/portage/.
</pre>

Edit the files in "etc/portage/package.*" and configure the portage tree.

<pre>
sed -i "s/amd64/arm/g" etc/portage/package.keywords/*
rm -r etc/portage/package.keywords/cross*
rm -r etc/portage/package.mask/cross*
rm etc/portage/package.use/cross*
rm etc/portage/package.env/cross*

mkdir etc/portage/repos.conf
cp usr/share/portage/config/repos.conf etc/portage/repos.conf/gentoo.conf
rm -f etc/portage/make.profile

(cd etc/portage && \
ln -s /usr/portage/profiles/default/linux/arm/13.0/armv7a/desktop make.profile)
</pre>

Copy the world file from the desktop computer and remove all packages which
should not be installed on the Pandora system.

<pre>
cp /var/lib/portage/world var/lib/portage/world
nano var/lib/portage/world
</pre>

=== Prepare cross-compilation and QEmu environment ===

A lot of packages will fail but we will keep going the emerge process and
compile the failed packages again with QEmu.

But first update the compiler tools in the target system. They will be needed
later in the QEmu environment. If they fail here, try to do it in the QEmu
part.

Copy the static QEmu binary to the target system and set up portage for the
target system.

<pre>
cp /usr/bin/qemu-arm usr/bin/.
mkdir -p usr/portage
touch usr/portage/.keep
</pre>

Do some standard setup for the target system. Copy some personal configurations
to the root account.

<pre>
cp -L /etc/resolv.conf etc/.
cp -r etc/skel/. root/.

cp /root/.bashrc /root/.dir_colors /root/.screenrc /root/.toprc \
/root/.xsession root/.
</pre>

Some nice tools like htop are worth to install them on the Pandora.

<pre>
mkdir -m0700 root/.config
cp -r /root/.config/htop root/.config/.
</pre>

To access the root account with ssh, copy its configuration. This copies the
"id_*" files, also. Don't do this if you deliberately take care about security.

<pre>
cp -r /root/.ssh/. root/.ssh/.
</pre>

=== Start cross compilation ===

Set up a cross compilation environment (use a third shell instance).

<pre>
bash
export CBUILD=x86_64-pc-linux-gnu
export CHOST=$CROSSDEV_TARGET
export ROOT=$PWD
export PORTAGE_CONFIGROOT=$ROOT
export PS1="($CHOST) $PS1"
</pre>

Try to cross compile all packages.

<pre>
$CHOST-emerge -a binutils glibc linux-headers gcc
$CHOST-emerge -ae @world
</pre>

If one of them fails, save the resume list.

<pre>
$CHOST-emerge -p --resume | grep "^\[[eb].*\]" | grep -ve "^\[blocks" | \
cut -b 18- | cut -d " " -f1 | awk '{ print("=" $0); }' >tmp/packages.txt
</pre>

Now go to "Continue cross-compilation with QEmu".

=== Continue cross-compilation with QEmu ===

Enter the chroot environment and emerge the failed package again (the first one
in the packages.txt file).

The portage tree will be mounted into the target system.

In the chroot environment it might be necessary to switch the compiler. Check
if the same version of gcc is used than the cross compiler with
"gcc-config -l". Set the correct version before starting "emerge".

<pre>
mkdir -p $PWD/run/systemd/resolve
cp /run/systemd/resolve/resolv.conf $PWD/run/systemd/resolve/.
mount --rbind /proc $PWD/proc
mount --make-rslave $PWD/proc
mount --rbind /sys $PWD/sys
mount --make-rslave $PWD/sys
mount --rbind /dev $PWD/dev
mount --make-rslave $PWD/dev
mount --rbind /usr/portage $PWD/usr/portage
chroot $PWD /bin/bash
unset CBUILD CHOST ROOT PORTAGE_CONFIGROOT
env-update
source /etc/profile
cd
source ./.bashrc
export PS1="(chroot) $PS1"
emerge -aB1 $(head -1 /tmp/packages.txt)
exit
umount -l usr/portage
umount -l dev sys proc
</pre>

After fixing the failed package(s), continue with the cross compiler.

<pre>
cat tmp/packages.txt | xargs $CHOST-emerge -1
</pre>

If one of them fails again, save the resume list.

<pre>
$CHOST-emerge -p --resume | grep "^\[[eb].*\]" | grep -ve "^\[blocks" | \
cut -b 18- | cut -d " " -f1 | awk '{ print("=" $0); }' >tmp/packages.txt
</pre>

*Go back to "Continue cross-compilation with QEmu" until all packages are merged
successfully.*

Remove some leftover temporary files.

<pre>
rm -rf /var/tmp/portage/* /usr/$CROSSDEV_TARGET/var/tmp/portage/* \
/usr/$CROSSDEV_TARGET/tmp/packages.txt
</pre>

== Fix lib64-problem ==

Some cross compiled packages install their libraries into the "lib64" directory.
This is not used on the Pandora. So we have to copy all contents from "lib64"
to "lib" and set a link for "lib64".

<pre>
rsync -avc usr/lib64/. usr/lib/.
rm -rf usr/lib64
(cd usr && ln -s lib lib64)
</pre>

== Configure system ==

Set the key map for Pandora in the console and, as usual in Gentoo,
configure the target system.

Use to make the Pandora keyboard work on the console.
[[File:Keymap-pandora.map|thumbnail|keymap-pandora.map]]

<pre>
cp "$FROM_DIR/keymap-pandora.map" etc/.
chmod 644 etc/keymap-pandora.map
echo >etc/vconsole.conf "KEYMAP=/etc/keymap-pandora.map"
echo >>etc/vconsole.conf "FONT=eurlatgr"
</pre>

Set up the mount table. Every line in "etc/fstab" will be commented out and
new entries added. The file system labels are used to mount the partitions.

<pre>
sed -ie "s,^/,#/,g" etc/fstab

cat >>etc/fstab <<EOF
LABEL=phlnx_boot /boot ext2 noauto,noatime 1 2
LABEL=phlnx_root / ext4 errors=remount-ro,noatime 1 1
LABEL=phlnx_home /home ext4 noauto,noatime,nodev,nosuid 1 2

Update the configuration files and read/clear all news from portage.

<pre>
dispatch-conf
eselect news list
eselect news read
eselect news purge
</pre>

Enter the time zone and generate the locale info you want (example: enable all
lines with en_US and de_DE).

<pre>
echo "Europe/Berlin" >/etc/timezone
emerge --config sys-libs/timezone-data
nano -w /etc/locale.gen
locale-gen
</pre>

Use en_US.utf8 (entry #9) as locale.

<pre>
eselect locale list
eselect locale set 9
</pre>

Set up mount table, the machine ID and host name.

<pre>
ln -sf /proc/self/mounts /etc/mtab
systemd-machine-id-setup
echo >/etc/machine-info "PRETTY_HOSTNAME=Pherkad"
echo >/etc/hostname "pherkad"
ln -snf /run/systemd/resolve/resolv.conf /etc/resolv.conf
systemctl enable systemd-resolved.service
</pre>

Exit the chroot environment.

<pre>
exit
umount -l usr/portage
umount -l dev sys proc
</pre>

Remove the QEmu binary. It is not used anymore.

<pre>
rm usr/bin/qemu-arm
</pre>

Also remove some leftovers from the cross compiler and the link to our kernel
sources.

<pre>
rm -f etc/portage/profile/package.provided
rm -f sys-include
rm -f usr/src/linux
</pre>

Copy back the target system and restore the previous cross compiler state.

<pre>

rm -rf /usr/$CROSSDEV_TARGET
tar -xpjf ${CROSSDEV_TARGET}-saved.tar.bz2 -C /usr
rm ${CROSSDEV_TARGET}-saved.tar.bz2
</pre>

Exit the root shell.

<pre>
exit
</pre>

== Update system ==

To update the system, use a similar approach as in the cross compilation phase.
Define CROSSDEV_TARGET as in "Install cross compiling system".

=== Start cross-compilation ===

Set up a cross compilation environment (become root and use a second shell
instance again).

<pre>
cd CrossDev

emerge --depclean crossdev
rm /usr/bin/repositories_configuration-*
exit
</pre>

== Create SD-card partitions phlnx_boot/root/swap/home ==

Finally the target system is done. Now it's time to copy it to the Pandora.

=== Pandora ===

It's recommended to partition the SD-card for the target system on the Pandora.
Otherwise the boot loader might refuse to work.

Insert the SD-card in the left slot (mmcblk0) and unmount it if necessary.

Create the following partitions:

* A boot partition (ext2).
* A root partition which will contain the target system (at least 4 GB).
* A home partition which we can use later.
* A SWAP partition which we can use later.

<pre>
sudo -s

/sbin/fdisk /dev/mmcblk0
Create new DOS partition label: o
Create new partition: n p 1 Return +8M
Create new partition: n p 2 Return +4G
Create new partition: n p 3 Return +1G
Change partition type: t 3 82 (Linux swap)
Create new partition: n p Return Return
Write all changes: w

/sbin/mkfs.ext2 -FL phlnx_boot /dev/mmcblk0p1
/sbin/mkfs.ext4 -FL phlnx_root -O ^has_journal /dev/mmcblk0p2
/sbin/mkswap -L phlnx_swap /dev/mmcblk0p3
/sbin/mkfs.ext4 -FL phlnx_home -O ^has_journal /dev/mmcblk0p4
exit
</pre>

== Option #1: Copy target system to SD-card ==

One of the possibilities to copy the target system to the SD-card on the Pandora
is to use a USB cable connecting the Pandora to the desktop computer.

It's also possible to copy it via the WiFi network (see below).

=== Pandora ===

Connect the Pandora via USB to the desktop computer. Insert the SD-card in the
left slot (mmcblk0). Use menu "System/SD-Mass Storage" to access partition
"phlnx_root".

=== Desktop computer ===

Mount the root partition and copy the target system. Use the correct "/dev/sd*".

<pre>
su
mkdir /tmp/mnt
mount /dev/sdc /tmp/mnt
mkdir -p /tmp/mnt/boot
touch /tmp/mnt/boot/.keep
mkdir -p /tmp/mnt/home
touch /tmp/mnt/home/.keep

rsync -av --delete --exclude lost+found --exclude /boot \
CrossDev/$CROSSDEV_TARGET/. /tmp/mnt/.

umount /tmp/mnt
</pre>

=== Pandora ===

Use "System/SD-Mass Storage" again to access phlnx_boot.

=== Desktop computer ===

Mount the boot partition and copy boot directory of the target system.

<pre>
mount /dev/sdc /tmp/mnt
rm -f /tmp/mnt/uImage-pherkad

rsync -av --delete --exclude lost+found \
CrossDev/$CROSSDEV_TARGET/boot/. /tmp/mnt/.

umount /tmp/mnt
rmdir /tmp/mnt
exit
</pre>

=== Pandora ===

End SD-Mass Storage.

== Option #2: Copy target system to SD-card via WiFi network ==

=== Pandora ===

Copy all files from the desktop computer to the SD-card partitions. Use the
same CROSSDEV_TARGET and FROM_DIR environment settings as on the desktop
computer.

<pre>
sudo -s
export REMOTE=mizar.spdns.de
export FROM_DIR=/home/jgeiss/Data/Systems/Pandora/Pherkad/Linux/Gentoo/CrossDev
export CROSSDEV_TARGET=armv7a-hardfloat-linux-gnueabi

mkdir -p /media/phlnx_root/boot
touch /media/phlnx_root/boot/.keep

rsync -av --numeric-ids --delete --exclude lost+found --exclude /boot \
$REMOTE:$FROM_DIR/$CROSSDEV_TARGET/. /media/phlnx_root/.

rsync -av --delete --exclude lost+found \
$REMOTE:$FROM_DIR/$CROSSDEV_TARGET/boot/. /media/phlnx_boot/.

exit
</pre>

== Boot the new system ==

Reboot the Pandora and hold the right shoulder button until the boot menu
appears.

'''Sometimes it is necessary to switch off the Pandora for 10-60 seconds.'''

Choose "boot from SD1:1".

It the boot works well, login as root and play around.

=== Optional: USB-networking ===

To use networking to the desktop computer via USB cable, execute the
following commands on both systems.

==== Pandora ====

<pre>
modprobe g_ether
ifconfig usb0 192.168.129.3 netmask 255.255.255.0
route add default gw 192.168.129.2
systemctl start sshd
</pre>

==== Desktop computer ====

Configure the corresponding network interface.

<pre>
ifconfig enp0s20u1u1 192.168.129.2 netmask 255.255.255.0
</pre>

Now you should be able to connect to the Pandora.

<pre>
ssh root@192.168.129.3
</pre>

=== Shutdown Pandora ===

To shutdown the Pandora system enter the following command.

<pre>
systemctl poweroff
</pre>

== Open issues ==

The following things are currently not working and need to be implemented/fixed:

* wl1251 board initialization failed
* tw1: not initialized
* omapfb omapfb: no displays, failed to setup omapfb
* omap2_set_init_voltage: unable to find boot up OPP vor ...
* __nand_correct_data: uncorrectable ECC error
* Buffer I/O error on dev mtdblock0, logical block 0, async page read
* Cursor and other GPIO-related keys do not work correctly if CPU is idle. Workaround: echo 1 >/sys/devices/system/cpu/cpu0/cpuidle/state4/disable
* Kernel panic at system shutdown
* fstab: Auto-Mounting /boot or /home causes system suspend after about 30 Seconds.
