In the months before the first preorders were taken, there was much discussion and community voting about the best layout. [http://www.gp32x.com/board/index.php?/topic/43762-pandora-keyboard-layout/ This] was one of the final votes. The final layout was different from either one of the two most popular community proposals, but incorporated some of the suggestions such as having a "Pandora" button.

Many desirable applications require a keyboard,general consensus was that an on-screen keyboard wasn't good enough. For computing mode, the game controls are used for mouse, cursor and control keys.

Some classic systems such as the Atari and C64, which had keyboards, are far more comfortably emulated on a device with a keyboard.

==Hotkeys==
'''alt+ctrl+ up / down''' | switches between virtual desktops. (if you put them in a single row in the widget you can use ← →) <br />
'''powerbutton slidelock left''' | locks keyboard nubs L and R shoulderbuttons <br />
'''pandorabutton + start''' | brings up a dialogue to kill processes <br />
'''Fn-L''' | Toggles TV-out on/off

==Keycodes==
This table might be useful if you're trying to map keys in some program, or writing a program:

The matrix layout is detailed on p.20 of the Hardware hacker's guide ([http://www.openpandora.org/downloads/PANDORA_Hackers_manual_v100.pdf here]). A more readable version appears below. A .svg version of the Pandora's keyboard layout (made by cosurgi) can be downloaded [http://www.mediafire.com/?8s157q5qj8dibjq here]. (broken link) {{FIXME|This should be embedded within this wiki.

==Remapping keys on the keyboard==
First, an apology - I'm writing this without knowing how to remap the keys on the [[keyboard]], so this is not really a tutorial. It is currently just a collection point for information on the subject.

===Reference===
Forum Threads
* [[http://www.gp32x.com/board/index.php?/topic/55124-remapping-the-mouse-buttons-etc/ Remapping The Mouse Buttons, Etc?]]
* [[http://www.gp32x.com/board/index.php?/topic/54077-changing-the-function-of-buttoms/ Changing The Function Of Buttoms]]
* [[http://www.gp32x.com/board/index.php?/topic/54324-remap-gaming-buttons-within-xfce Remap Gaming Buttons Within Xfce]]

The os should allow the standard keypad and modifier keys to be defined to generate any key. So if you want shift '1' to be anything other than 'section', it is possible. somehow :(

===Linking events to Keys===
There is a Pandora event map daemon, which reacts to the lid close, Pandora button and power button.
It can be configured using the <pre>/etc/pandora/conf/eventmap</pre> file. How to reference additional special keys is TBD. A thread showing an example is [[http://www.gp32x.com/board/index.php?/topic/54944-xfce-style-changing-with-brightness-buttons-hack/ here]]
It is also possible to configure xfce to capture events (forum thread is not locatable today)

===Using shoulder buttons for mouse===
{{hint|Seems only to be reported working permanently on HF4 but see NOTE below}}
As described in this [http://www.gp32x.com/board/index.php?/topic/55124-remapping-the-mouse-buttons-etc/page__view__findpost__p__896576 post]
# Find the keycodes which you want to modify. Run '''xev''' (this needs to be installed from angstrom repo) from the terminal, and record the numbers.
# Edit the '''.pndXmodmap''' file in your home directory, modify or add (in the correct numerical order for ease) lines like this (for the shoulder buttons)
<source lang="bash">
keycode 62 = Pointer_Button1 NoSymbol Pointer_Button1
keycode 105 = Pointer_Button3 NoSymbol Pointer_Button3
</source>
# If you want to use the 'a' and 'b' buttons, the codes are 110 and 115 respectively.
# As a test, open the XFCE Accessibility settings and enable mouse keys.
# To make this permanent, download a compiled version of [http://urjaman.dy.fi/xkbset xkbset], copy to /usr/bin and chmod a+x /usr/bin/xkbset
# Create a script (file) with this as content
<source lang="bash">#!/bin/sh
xkbset m
xkbset exp =m</source>
# Now open a terminal where the file is saved, and give it executable permissions:
#:<source lang="bash">chmod +x nameofyourfile.sh</source>
#Now install it:
#:<source lang="bash">sudo cp nameofyourfile.sh /usr/bin/nameofyourfile</source>
# Add this script to XFCE autostarted stuff (Session and Startup->Application Autostart)
NOTE
# For HF5 you only need add these two commands to .xinitrc (located in your home directory)
<pre>xkbset m
xkbset exp m</pre>
note the missing =(equals) sign

===Swapping Caps Lock and Tab===
As a command line junkie, I was pretty frustrated with where Tab is. I decided to remap it to where Caps Lock is (Fn + Shift). I added the following to .pndXmodmap (in your home directory):
<pre>keysym Tab = Caps_Lock
remove Lock = Caps_Lock
keycode 66 = Tab NoSymbol Tab
add Lock = Caps_Lock</pre>
After you add this, just run "xmodmap ~/.pndXmodmap" to reload the keymappings

== Keyboard layout changer tool ==

The '''keyboard layout changer''' provides a means to easily change keyboard layout. Possible uses are for typing in a different language on your Pandora, for using an external keyboard, or simply for making small key modifications.

=Usage guide=
#Download the PND to your Pandora from either [http://stuffs.slaeshjag.org/pnd/kblayout.pnd Slaeshjag's site] or from the [http://repo.openpandora.org/?page=detail&app=change-keymap-0.1-slaeshjag Repo] (see [[User_manual#Installing_a_PND_file_.28an_application.29|here]] for instructions on where to place PNDs)
#Run the PND; it's called "Keyboard Layout" and is in the "Settings" category
#You will now see a choice of keyboard layouts. Choose one, and your layout will change!<br/>(if the program doesn't run, find the <code>/tmp/pndrun_kblayout.out</code> file and post its contents in the [http://boards.openpandora.org/index.php?/topic/2428-keyboard-layout-changer/ official forum thread], so that the author can see what went wrong)

==Keyboard layouts==

[http://repo.openpandora.org/?page=detail&app=change-keymap-0.1-slaeshjag Keyboard layout] is an app by slashjag which helps you change layout in a graphical interface.

=== Make your own ===

*Go to the <code>/media/yourSDcard/pandora/appdata/kblayout/keymaps</code> directory. Inside, you will see a bunch of files. Open any one with a text editor, and you'll see something like this:

./setxkbmap -layout us
xmodmap ~/.pndXmodmap

What this means is that it's using the "us" layout with the modifications specified in the ".pndXmodmap" file (the Pandora needs these modifications because its keyboard isn't the same as a standard one).

So there are two basic things you could change: you could replace "us" with a different base layout, or you could replace "~/.pndXmodmap" with a different file.

===Base layouts===
The default layout is "us". The full list of base layouts included with the Pandora is listed in the file <code>/usr/share/X11/xkb/keymap/xfree86</code>. Here's the full list:
{{HideableNotes|<pre>
us
ar
be
bg
br
cz
de
ch_de
ch_fr

dvorak
en_US
es

tr
uk
us_flexpro
us_intl
us_microsoft
uz
cz_qwerty
de_CH
fr_CH
mt_us
sk_qwerty
</pre>}}

If you just want to use one of these base layouts with no modifications, make a new file in the <code>/media/yourSDcard/pandora/appdata/kblayout/keymaps</code> directory, name it anything, open it in a text editor and place the following text inside, replacing "xx" with any of the codes in the above list:
./setxkbmap -layout xx
Save the file. Then just start Keyboard Layout Changer, and you'll be able to select it.

===xmodmap===
This type of file modifies whatever base layout is selected. One of these comes by default with your Pandora OS. You can find the <code>.pndXmodmap</code> file in the <code>/home/username</code> directory. It might be hidden, so press Ctrl+H to make it visible. If you open it with a text editor, you'll see this:

Ok, now let's break this down a little. <code>keycode 38 = a A a A</code> - the first two letters after the = sign are what you'll get if you press the button marked A with and without holding "shift". The next two are with and without shift modifier together with a second modifier, but since there's no second modifier on the Pandora, this is redundant really. What about Fn, you may ask, isn't that a second modifier? The Fn-key acts on a lower level, and is not seen as a separate key. Instead, there are separate keycode entries for all Fn keys (the ones marked in blue on your Pandora). "NoSymbol" means that the combination doesn't produce a character. You can find a full list of symbols (or "keysyms") that you can use [http://wiki.linuxquestions.org/wiki/List_of_Keysyms_Recognised_by_Xmodmap over here].

You can edit the .pndXmodmap file itself if you want to. That'll change the default keyboard layout you have at startup.

But you can also make secondary custom keyboard layouts.

For example, here's how to make a selectable custom Russian keyboard layout:

====Making a custom Russian keyboard layout====
Make two new files inside <code>/media/yourSDcard/pandora/appdata/kblayout/keymaps</code>. One called "RU-translit" (the name doesn't matter), one called ".rumodmap" (the dot at the start of the name is to make it not show up in the Keyboard Layout Changer menu as a keymap; that's the function of the ''first'' file you made). Put this text in the RU-translit file:
./setxkbmap -layout us
xmodmap keymaps/.rumodmap

Put this text in the .rumodmap file:

{{HideableNotes|<pre>keycode 9 = Escape NoSymbol Escape

Once that's done, you can open the Keyboard Layout Changer, choose "RU-translit", and your keyboard layout will change to a layout similar to [http://i.imgur.com/O96Pu.gif this one], with extra letters replacing F1-F7 (note: for those 7 letters, you can only use the Shift on the Pandora's front face, not the left shoulder button). To change back, open Keyboard Layout Changer again and select "default".

In the same way, you can create any other sorts of custom layouts. The easiest way to create a new modmap file is to copy+paste the contents of <code>/home/username/.pndXmodmap</code> into a new file in the <code>/media/yourSDcard/pandora/appdata/kblayout/keymaps</code> directory and make adjustments to whatever you want to change.

==How many keypresses can it detect at once?==
It can detect two "regular" keys being pressed at once[http://www.gp32x.com/board/index.php?s=&showtopic=44326&view=findpost&p=651104]. However, this restriction does not apply to the game controls, or the central "Menu" keys.

DraStic Compatibility List

2013-12-20T06:20:14Z

Urjaman: typo fix

DraStic is a Nintendo DS Emulator created by Exophase for ARM devices such as the OpenPandora.

* [http://repo.openpandora.org/?page=detail&app=DraStic Download]
* [http://exophase.devzero.co.uk/drastic_readme.txt Readme and Changelog]
* [http://boards.openpandora.org/index.php/topic/12038-emulator-drastic-nintendo-ds/page-1 Forum Thread]

The current version on the Repo is 2.1.6.1, released on Sept. 17th, 2013. It identifies itself as "Version r2.1.6.1p" on the menu screen.

* [http://pandorawiki.org/DraStic_Compatibility_List_1.x Outdated Previous 1.x Version Compatibility List]

==Compatibility==
''128MB+ zipped games have issues on CC Pandoras because of limited RAM. 256MB zipped games may work on 512MB systems such as the Rebirth or 1GHz Pandora. 512MB zipped games are not expected to run on any system. Unzipped games of any size are not dependent on RAM, so should work the same on all systems.　Note that wifi is not emulated or faked so far, so it may lead to compatibility issues/crashes.''

==Adding to the list==
Note: you can use the [http://repo.openpandora.org/?page=detail&app=drasticwikihelper-PowerGod Drastic Wiki Helper] application from the repo to automatically generate appropriate text to paste in the compatibility list below.

Choose a playability color that reflects a game's best playability state. Also include the clockspeed at which you ran it, for whichever Pandora version you tested. Please also indicate in the name of the Game whether the version is US/EU/JP, since compatibility may differ depending on regions. Include the unzipped ROM size in base-2 mebibytes (16MB, 64MB, 128MB, etc.). If available please indicate the game ID figure, too. The Game ID figure should be 8 characters long and can usually be found by pressing Y on the rom selection menu.

'''Don't''' post a redundant entry unless you are using a different Pandora model and the playability differs from an existing entry. If a game's playability gets worse (new bugs, new crashes) in a new DraStic version, update the entry and add that to notes. Please don't copy entries from the old list into this one unless you first re-test the game using a recent version of DraStic and update the color and notes as required.

Default frameskip for version 2.0.1p is automatic and 4. Please record a comment if you use a different setting.

Cross-compiler

2013-12-06T00:34:15Z

Urjaman: Lets try that out for a moment

One of the ways to compile your applications to the ARM architecture is through a cross-compiler. This will allow you to compile applications for the ARM architecture on a different system. This is good if you want to develop for the Pandora but are still waiting to receive it, or if you have an application that takes too much memory or drive-space to effectively compile on the Pandora itself. At the moment, there are 4 different ways you can set up a cross compiling environment.

These options are sorted in '''order of preference'''. Option two is preferred over three, etc.

== A native compilation solution (with optionally distcc) ==
http://cloudef.eu/pandora/dchrt/

Instructions: [http://cloudef.eu/pandora/dchrt/README here]
2013

The chroot and most of the tools are by urjaman, some of the ipk's and mirroring/hosting by Cloudef.
< Cloudef> urjaman: make it "Obvious solution for elitists"

== Ivanovic's CodeSourcery-Based Cross Compiler ==
{{warning|This toolchain won't work on a pure 64bit system.}}
This toolchain is based on previous codesourcery toolchain attempts but uses the packages that openpandora relies on. It should work for every Linux system that can make use of x86 binaries (meaning x86 systems as well as amd64 systems with multilib support). A detailed explanation of the SDK as well as the script required to install it are available in [http://boards.openpandora.org/index.php?/topic/7147-crosscompiler-toolchain-based-on-openpandoraorg-ipks/ this forum thread]. 2012

'''Notes''':
* This toolchain works on a 64-bit system, assuming 32-bit compatibility libraries are installed. On Debian, they can be installed with:
<source lang="bash">aptitude install ia32-libs-dev</source>

== Sebt3's Yactfeau ==
http://www.gp32x.com/board/index.php?/topic/58490-yactfeau/
2011
'''Notes''':
* This toolchain works on a 64-bit system, assuming 32-bit compatibility libraries are installed. On Debian, they can be installed with:
<source lang="bash">aptitude install ia32-libs-dev</source>

=== Using the Toolchain ===
# If you don't already have a Linux-based system you want to use, download and run the [http://sebt3.openpandora.org/buildtools/?f=pandora-virtualbox-image.7z Pandora VirtualBox Image].
# Remove your previous installation by running (default password is devel):
#:<source lang="bash">sudo rm -rf /usr/local/angstrom/arm/*</source>
# Download the [http://sebt3.openpandora.org/buildtools/?f=pandora-toolchain-20110313.tar.bz2 toolchain] ([http://sebt3.openpandora.org/buildtools/pandora-toolchain-20110313.torrent torrent]).
# Unpack the toolchain:
#: <source lang="bash">sudo tar -C /usr/local/angstrom/arm -xjf pandora-toolchain-20110313.tar.bz2</source>
# Fix file permissions:
#: <source lang="bash">sudo chown -R <your-name>.<your-name> /usr/local/angstrom/arm</source>
# Install the toolchain:
#: <source lang="bash">$ bash /usr/local/angstrom/arm/scripts/installer.sh</source>
# Download updated [http://sebt3.openpandora.org/buildtools/?f=genpxml genpxml] script and overwrite old one:
#: <source lang="bash">$ mv genpxml /usr/local/angstrom/arm/scripts/genpxml</source>

=== Common Errors ===
==== No such libmpfr.so.1 ====
If you get the following error message while trying to compile projects:
error while loading shared libraries: libmpfr.so.1: cannot open shared object file: No such file or directory
You can fix that by commenting out the following lines of the "environment-setup" file:
# if [ ! -e "/usr/lib/libgmp.so.3" ] || [ ! -e "/usr/lib/libmpfr.so.1" ];then
(...and 7 lines later...)
#fi

== DJWillis's Cross Compiler ==
You could try the easy-to-setup environment described on [http://blogs.distant-earth.com/wp/?p=109 DJWillis' blog] 2010 which is suitable for 32bit Linux. However, the process is also expanded further below.

DJ-Willis's cross-compiling toolchain page is really awesome, but it has a few holes I'd like to patch up in this guide. Here, we'll be creating a chroot jail to install the toolchain on with a Debian Squeeze system. This will allow you to use DJ Willis's toolchain without mucking with your normal system at all. Of course, it's obviously overkill, but, hey, what's technical insight without it?

The commands are detailed exactly as you'll need to enter them, from start to finish, to compile Pandora native apps on your host system. They'll run really well on the Pandora, but they won't run on your host. To do that, you'll need to compile them for the host system, which is a different, but much simpler, process.

=== Resources ===
The following are generic resources you might want to read up on to make better sense of the instructions that follow.

* http://blogs.distant-earth.com/wp/?p=109
* http://wiki.debian.org/chroot
* http://wiki.debian.org/Debootstrap
* http://pandorapress.net/2009/03/11/so-you-want-to-try-angstrom/

=== Instructions ===
The following instructions are for a (Debian) host system that you have root access to. The system-inside-a-system you're building will probably take about 1 GiB of hard-drive space.

<source lang="bash">
cd ~
mkdir pandora_cross_compiler
su -c "apt-get install debootstrap chroot" # get the dependencies
su -c "debootstrap --arch=i386 squeeze pandora_cross_compiler" # see the debootstrap wiki
su -c "LANG=C chroot pandora_cross_compiler /bin/bash" # see the chroot wiki
apt-get install bzip2 unzip curl libmpfr-dev
ln -s /usr/lib/libmpfr.so /usr/lib/libmpfr.so.1
cd ~
wget http://djwillis.openpandora.org/toolchains/20100611-i686-linux-armv7a-linux-gnueabi-toolchain-openpandora.tar.bz2 http://djwillis.openpandora.org/toolchains/DisplayImage.zip
tar -C / -xjf 20100611-i686-linux-armv7a-linux-gnueabi-toolchain-openpandora.tar.bz2
unzip DisplayImage.zip
. /usr/local/angstrom/arm/environment-setup
arm-angstrom-linux-gnueabi-gcc -Wall DisplayImage.c -o DisplayImage -l SDL
exit
</source>

Congratulations! You just compiled an ARM-based executable! It won't run on the Intel 32-bit system you're testing it on! To see it not run on your normal system, run:
<source lang="bash">
su -c "cp pandora_cross_compiler/root/DisplayImage .; cp pandora_cross_compiler/root/test.bmp ."
su -c "chown (your user):(your group) DisplayImage test.bmp"
./DisplayImage
</source>

You compiled it for the Pandora. If you have a Pandora, copy it to the Pandora and it should work.

To get back into your chroot jail to compile more programs that you can copy then back into your normal system and your Pandora, you'll just need to run:

<source lang="bash">su -c "LANG=C chroot pandora_cross_compiler /bin/bash</source>

And Bam! You're back in the chroot.

Consider using QEmu to create an ARM VM for testing the programs. See the Pandora Press link for those instructions. Also see the comments for getting the QEmu image to run in Linux.

== Using the SDK-Installer ==
Cpasjuste on the GP32X forums has made a nice script to get a build environment and libraries installed on Ubuntu/Debian systems. Download links and a brief explanation can be found in [http://www.gp32x.com/board/index.php?/topic/52343-pandora-sdk-installer/ this thread].

A new approach at creating a crosscompiler toolchain was done by Ivanovic. It is based previous codesourcery toolchain attempts but uses the packages that openpandora relies on, too. It should work for every Linux system that can make use of x86 binaries (meaning x86 systems as well as amd64 systems with multilib support). A more detailed explanation of the SDK as well as the scripts required to install it are available in [http://boards.openpandora.org/index.php?/topic/7147-crosscompiler-toolchain-based-on-openpandoraorg-ipks/ this thread].

== Manual Installation ==
If you want a bit more control, Code-Sourcery hosts a bunch of cross-compiling suites for various platforms on their site, some editions have to be paid for, but they do have "lite" editions without support that are completely free.

Head up onto [http://www.codesourcery.com/sgpp/lite/arm/portal/subscription3057 here]. The recommended release at time of writing is [http://www.codesourcery.com/sgpp/lite/arm/portal/release1039 2009q3].

Installers are available for Linux and Windows. Alternatively, download and unpack the tarball, then add the bin directory to your path.

=== Example: Setting up a cross compiler using Code Sourcery, and doing so inside a VM ===
Skeezix makes some notes in [http://fw.skeleton.org/~jeff/blog2009/2010/06/02/getting-up-and-going-with-a-crosscompiler-for-pandora-arm-in-5-minutes/ his blog] about setting up CodeSourcery's prebuilt toolchain in a VM very quickly.

== Possible Problems ==
If you get an error when compiling along of the lines of "error while loading shared libraries: libmpfr.so.1: cannot open shared object file: No such file or directory", run
<source lang="bash">apt-get install libmpfr1ldbl</source> and attempt to compile again.

Cross-compiler

2013-12-06T00:32:03Z

Urjaman: Fix that awfulness

One of the ways to compile your applications to the ARM architecture is through a cross-compiler. This will allow you to compile applications for the ARM architecture on a different system. This is good if you want to develop for the Pandora but are still waiting to receive it, or if you have an application that takes too much memory or drive-space to effectively compile on the Pandora itself. At the moment, there are 4 different ways you can set up a cross compiling environment.

These options are sorted in '''order of preference'''. Option two is preferred over three, etc.

== A native compilation solution (with optionally distcc) ==
http://cloudef.eu/pandora/dchrt/

Instructions: [http://cloudef.eu/pandora/dchrt/README here]
2013
The chroot and most of the tools are by urjaman, some of the ipk's and mirroring/hosting by Cloudef.

== Ivanovic's CodeSourcery-Based Cross Compiler ==
{{warning|This toolchain won't work on a pure 64bit system.}}
This toolchain is based on previous codesourcery toolchain attempts but uses the packages that openpandora relies on. It should work for every Linux system that can make use of x86 binaries (meaning x86 systems as well as amd64 systems with multilib support). A detailed explanation of the SDK as well as the script required to install it are available in [http://boards.openpandora.org/index.php?/topic/7147-crosscompiler-toolchain-based-on-openpandoraorg-ipks/ this forum thread]. 2012

'''Notes''':
* This toolchain works on a 64-bit system, assuming 32-bit compatibility libraries are installed. On Debian, they can be installed with:
<source lang="bash">aptitude install ia32-libs-dev</source>

== Sebt3's Yactfeau ==
http://www.gp32x.com/board/index.php?/topic/58490-yactfeau/
2011
'''Notes''':
* This toolchain works on a 64-bit system, assuming 32-bit compatibility libraries are installed. On Debian, they can be installed with:
<source lang="bash">aptitude install ia32-libs-dev</source>

=== Using the Toolchain ===
# If you don't already have a Linux-based system you want to use, download and run the [http://sebt3.openpandora.org/buildtools/?f=pandora-virtualbox-image.7z Pandora VirtualBox Image].
# Remove your previous installation by running (default password is devel):
#:<source lang="bash">sudo rm -rf /usr/local/angstrom/arm/*</source>
# Download the [http://sebt3.openpandora.org/buildtools/?f=pandora-toolchain-20110313.tar.bz2 toolchain] ([http://sebt3.openpandora.org/buildtools/pandora-toolchain-20110313.torrent torrent]).
# Unpack the toolchain:
#: <source lang="bash">sudo tar -C /usr/local/angstrom/arm -xjf pandora-toolchain-20110313.tar.bz2</source>
# Fix file permissions:
#: <source lang="bash">sudo chown -R <your-name>.<your-name> /usr/local/angstrom/arm</source>
# Install the toolchain:
#: <source lang="bash">$ bash /usr/local/angstrom/arm/scripts/installer.sh</source>
# Download updated [http://sebt3.openpandora.org/buildtools/?f=genpxml genpxml] script and overwrite old one:
#: <source lang="bash">$ mv genpxml /usr/local/angstrom/arm/scripts/genpxml</source>

=== Common Errors ===
==== No such libmpfr.so.1 ====
If you get the following error message while trying to compile projects:
error while loading shared libraries: libmpfr.so.1: cannot open shared object file: No such file or directory
You can fix that by commenting out the following lines of the "environment-setup" file:
# if [ ! -e "/usr/lib/libgmp.so.3" ] || [ ! -e "/usr/lib/libmpfr.so.1" ];then
(...and 7 lines later...)
#fi

== DJWillis's Cross Compiler ==
You could try the easy-to-setup environment described on [http://blogs.distant-earth.com/wp/?p=109 DJWillis' blog] 2010 which is suitable for 32bit Linux. However, the process is also expanded further below.

DJ-Willis's cross-compiling toolchain page is really awesome, but it has a few holes I'd like to patch up in this guide. Here, we'll be creating a chroot jail to install the toolchain on with a Debian Squeeze system. This will allow you to use DJ Willis's toolchain without mucking with your normal system at all. Of course, it's obviously overkill, but, hey, what's technical insight without it?

The commands are detailed exactly as you'll need to enter them, from start to finish, to compile Pandora native apps on your host system. They'll run really well on the Pandora, but they won't run on your host. To do that, you'll need to compile them for the host system, which is a different, but much simpler, process.

=== Resources ===
The following are generic resources you might want to read up on to make better sense of the instructions that follow.

* http://blogs.distant-earth.com/wp/?p=109
* http://wiki.debian.org/chroot
* http://wiki.debian.org/Debootstrap
* http://pandorapress.net/2009/03/11/so-you-want-to-try-angstrom/

=== Instructions ===
The following instructions are for a (Debian) host system that you have root access to. The system-inside-a-system you're building will probably take about 1 GiB of hard-drive space.

<source lang="bash">
cd ~
mkdir pandora_cross_compiler
su -c "apt-get install debootstrap chroot" # get the dependencies
su -c "debootstrap --arch=i386 squeeze pandora_cross_compiler" # see the debootstrap wiki
su -c "LANG=C chroot pandora_cross_compiler /bin/bash" # see the chroot wiki
apt-get install bzip2 unzip curl libmpfr-dev
ln -s /usr/lib/libmpfr.so /usr/lib/libmpfr.so.1
cd ~
wget http://djwillis.openpandora.org/toolchains/20100611-i686-linux-armv7a-linux-gnueabi-toolchain-openpandora.tar.bz2 http://djwillis.openpandora.org/toolchains/DisplayImage.zip
tar -C / -xjf 20100611-i686-linux-armv7a-linux-gnueabi-toolchain-openpandora.tar.bz2
unzip DisplayImage.zip
. /usr/local/angstrom/arm/environment-setup
arm-angstrom-linux-gnueabi-gcc -Wall DisplayImage.c -o DisplayImage -l SDL
exit
</source>

Congratulations! You just compiled an ARM-based executable! It won't run on the Intel 32-bit system you're testing it on! To see it not run on your normal system, run:
<source lang="bash">
su -c "cp pandora_cross_compiler/root/DisplayImage .; cp pandora_cross_compiler/root/test.bmp ."
su -c "chown (your user):(your group) DisplayImage test.bmp"
./DisplayImage
</source>

You compiled it for the Pandora. If you have a Pandora, copy it to the Pandora and it should work.

To get back into your chroot jail to compile more programs that you can copy then back into your normal system and your Pandora, you'll just need to run:

<source lang="bash">su -c "LANG=C chroot pandora_cross_compiler /bin/bash</source>

And Bam! You're back in the chroot.

Consider using QEmu to create an ARM VM for testing the programs. See the Pandora Press link for those instructions. Also see the comments for getting the QEmu image to run in Linux.

2013-10-31T13:27:22Z

Urjaman: /* Ext Connector */ updated the situation

{{introNote|About custom hardware extensions, see also [[Kernel interface]]}}
==Official Hackers Manual==
There is a LOT of great information in this:
[http://www.openpandora.org/downloads/PANDORA_Hackers_manual_v101.pdf Pandora Hackers Manual v1.01 by MWeston]

==Pinouts==
Here's a list of pinouts for the various connectors and boards.

Here's a pic of the board, some of the pinouts can be seen on it. [http://pandorapress.net/files/2010/02/rev5.jpg]

==Ext Connector==
[[Image:Cable_connector pinout.png|thumb|TV cable connector]]
''What does it have?''
* UART2
* UART3
* TV out
* Stereo line out
* Stereo line in
* The UART lines can also be used as GPIO (six of them) and PWM lines (four of them).

''Where can we get the connectors from?''
* Just for reference: the pandora-side of the connector is Tyco 1717312-1, you already have that.
** dragonbox.de is selling the compatible Astron 3111014-301-R.
** The matching connector from Tyco is number 1717169-2 - this is the connector compatible with the tinyBobs already produced.
*** The manufacturer does *not* stock these for engineering samples, and very few vendors carry them
*** Community member [http://boards.openpandora.org/index.php?/user/157-wizardstan/ WizardStan] has ordered a bunch and is selling them at $2 a piece plus shipping from Canada, [http://boards.openpandora.org/index.php?/topic/2675-ext-connectors/ see here (thread)] or [http://pandorapress.net/2011/05/18/ext-connectors-have-arrived/ here (article)]
===How Do I Make a TV-Out Cable?===
* There are some useful tips in the [http://boards.openpandora.org/index.php?/topic/2675-ext-connectors/ EXT Connectors] thread.
* A guide explaining one way of creating the video cables can be found [http://dl.openhandhelds.org/cgi-bin/pandora.cgi?0,0,0,0,23,465 here]
* MarkoeZ Has written a blog post about it [http://markoez.pirategames.co.uk/index.php/blog/pandora-ext-tv-out-explained/ here]

==Battery==
[[Image:Battery.jpg|thumb]]
* 3.7V
* Lithium polymer single cell battery
* 4000 mAH, 4 AH

* LTPS (8-bit parallel input for R, G and B, with separate horizontal and vertical sync)
* 3.0V

===UART===
* UART2 and 3 are available via the EXT connector, and via internal solder pads on the latest revision
** UART2 appears to support hardware flow control with RTS/CTS lines
** On the 2.6.27 Kernel UART3 is /dev/ttyS0
** On 2.6.37 or later, UART2 is accessible through /dev/ttyO1, UART3 is on /dev/ttyO2

===GPIO===
* 6 are available on the EXT connector
* 7 are internal, 2 of which can be used as extra shoulder buttons
* 1 located on the LCD cable

===JTAG===
* Yes, 1.8V 10-pin (board label JTAG)

===I<sup>2</sup>C===
* One at 1.8V from the OMAP (board label I2C3-1V8)
* One at 2.8V (board label I2C3-2V8)

=== USB ===
* No internal USB ports

===Keypad backlight===
* ?

===Extra LEDs===
LED7 and LED8 can be added. You need to add FETs (Q17 and Q18) and resistors (R165, R166, R167 and R168)
See the official "Pandora Hacker Guide" from Michael Weston for more details and component values.

==Breakout Board==
[[Image:Breakoutboard.jpg|thumb|alt=Developer's breakout board|Developer's breakout board]]
This is the breakout board used by Pandora team members during development. Only a small number were made, and they are not available to the public. However a similar product (or gerber files) may be released in the future. A schematic for this board is available here: http://openpandora.ca/schematic/AV_Board_schematic.pdf

Power modes

2013-02-19T01:43:05Z

Urjaman: /* Charging */

[[Image:Battery.jpg|thumb|The Pandora's battery]]

==Power Modes==

Without switching the device entirely off, it may be placed into low power mode or regular power mode; simply pressing the power button will toggle modes. Note that as of [[hotfix3]], opening the lid in low power mode has no effect.

===Normal Mode===
This is the normal operating mode, [[display]] on, [[WiFi]] and [[Bluetooth]] on if requested. [[CPU speed]] can be selected by the user, and has a small impact on battery life. Screen brightness will also have a significant effect on battery life. The CPU should automatically self-regulate to the current task, and 10-20 hours [[battery]] life is possible depending on usage. This is mostly independent of the set CPU speed for any given task. At any time, the battery gauge will show the remaining battery life ''if the usage remains the same as over the past some seconds''.
See [http://boards.openpandora.org/index.php?/topic/10738-pandora-power-consumption-breakdown/] for a detailed breakdown of power consumption.

===Lid Closed===
The only change with the lid closed is to turn off the LCD [[backlight]] and the display itself. This improves battery life, allowing music playback and streaming to continue. As of [[Hotfix2]], the screen remains on if the device is powered up with the lid closed. It is also possible to set [[xfce]] to blank the screen after a period of inactivity, which helps with battery.

===Low Power===
Low power mode is toggled by a short press of the [[power switch]] to the right. The screen is off, the [[radios]] are disabled, the CPU max speed is set to 14 MHz. The device is still silently on, allowing for alarms to go off or it to be turned on again instantly. The power [[LED]] will be dimmed, and may appear to be off if you are outside.

Low power mode is probably going to be used as the normal "off" for most people, with true off (device powered down entirely, unable to respond to alarms or wake up quickly) available to conserve battery power. Turning the Pandora off completely is the best option if you don't plan on using it for few days or longer.

Since the Pandora has to be powered whilst it is charging, low power mode is best for fastest charging, and will even allow a full charge to be achieved from [[USB]]. It is also the best way to use the Pandora as a [[USB]] charger for other devices.

Opening the [[screen]] whilst in low power mode has no effect (screen stays off, clocks stay low), and you will need to use the power switch to resume.

At the moment, there is no clear advantage in slowing the clocks (other than being an effective pause button when playing MP3). The only saving is through disabling the radios. This is likely to be improved in due course since there are features in the omap processor for power saving which are being added to the linux [[kernel]].

===Power Off===
Select Logout then Shutdown from the window manager to power off. If a charger is connected, the device will re-boot immediately. It is possible to get into a state where you believe it is powered off, but in fact it is using power at the normal screen off rate - so after 12 hours, 50% of your battery is gone. The Power green [[LED]] ought to be a tell-tale. It is possible that some bugs exist in this area, but nothing has been clearly identified[http://www.gp32x.com/board/index.php?/topic/54652-solved-pandora-lost-charge-overnight/]

A common problem seems to be that if you switch off ''before'' unplugging, your Pandora will re-boot even though it is now left unplugged. This problem is compounded by the low battery shutdown script being called repeatedly (and actually preventing shutdown).

To do a '''hard-reset''' of the Pandora (in case of software crashes), press and hold the [[Pandora key]] and flick the power button to the right.

To do a '''hard-shutdown''' of the Pandora, press and hold the Pandora key ''with right shoulder button held'' and flick the power button to the right, and then select shutdown from the menu.[http://www.gp32x.com/board/index.php?/topic/59233-hf5-not-shutting-down-or-rebooting/page__view__findpost__p__946375]

==Events==
The events which control power can be customised [http://www.gp32x.com/board/index.php?/topic/54544-forcing-shutdown-at-10-battery-life/page__view__findpost__p__878418]. Lid switch, Power Switch, battery threshold and Window Manager shutdown commands. Note that the battery manager in xfce will also take action when the battery is low, by default forcing a shutdown at 5% (so you may observe a full boot process, the window manager appears, then immediately shuts down)

==Charging==
[[image:Power_uk.png|thumb|alt=UK charger and adapter|UK charger and adapter]]
It is possible to charge from the mains charger (use the supplied one or a ''GENUINE'' PSP adaptor only) or [[USB]] cable. While a charger is connected, remaining [[battery]] level is displayed, but the time displays 00:00. If charging from USB, it is possible that the battery will still discharge slowly, since the Pandora takes more current (in normal mode) than the USB can supply. Mains charge is configured to draw 1000mA, USB charge is more like 600mA.

It is not possible to charge the Pandora without turning it on - connecting the mains charger or the USB cable will turn it on automatically. The normal charging circuits rely on the CPU for configuration. In practice, this has minimal impact on usage, except that after charging,

you might wish to explicitly turn off (and maybe there is a easy way to automate this by adding a charger event to call a script).

Full discharge charging: The pandora will shutdown in case of low battery power. However there is a protection circuit in the battery itself which will cut off the power output of the battery. The battery and the pandora seems to be dead in this condition, but it's not. If you plug in the power

you'll see nothing happen - but the battery will be recharged very slowly until the battery is above it's cutoff level. This could take up to 30 minutes. Then the pandora will startup and the normal CPU controlled faster charging will continue.
[http://boards.openpandora.org/index.php?/topic/8426-battery-completely-dead/#entry150209]


If your Pandora's [[battery]] is at less than 1% (actually configurable in [[XFCE]]), then you may have problems in using [[USB]] to charge the Pandora. Currently, [[USB]] is not recognised by the [[XFCE]] battery monitor so it will shutdown with no warning. As a workaround, you can put your Pandora into low power mode as soon as the flashing mouse icon (XFE startup) appears. This should significantly delay loading the battery monitor widget, and even if the charge hasn't passed 1% by the time it checks, on the next try you should be there.

==Operating Point==
The ''OPP'' is a TI term which reflects the fact that low clock speeds can be achieved with lower supply voltage than the higher clock speeds. Increasing OPP will reduce the lifetime of the device significantly (from 10 years to 5 years of continuous use.) OPP3 is the default as shipped by OpenPandora. As of Hotfix4, it is possible to set a maximum OPP in the range 1-5 (for example, to 5):
<source lang="bash">echo 5 | sudo tee -a /proc/pandora/cpu_opp_max</source>
This will then increase OPP to suit the requested CPU max, as pre-determined by a table built in to the kernel. These thresholds use OPP1 for below 125 MHz, and OPP5 for above 720 MHz. It is possible to set the limiter and maybe run at 500 MHz in OPP2 (depending on your specific chip). See [http://boards.openpandora.org/index.php?/topic/22-using-hotfix4-how-high-can-you-clock/ this forum thread] for actual results.

{{warning
|Using anything above OPP3 WILL shorten the lifetime of your Pandora, although it should still outlive the 1 year warranty. Using anything above OPP5 and 1Ghz will void your warranty (see [[Overclocking#Warranty_information|here]])
}}

Tweaking scripts to make this tuning easier are in the works.

==Monitoring==
The [[kernel]] provides some information about battery state through the filesystem. See [[Data_provided_by_Battery_and_Power_driver]]. This may help with diagnosing problems.

==Times==
* This data originates from different studies performed under different OS versions and use cases.
* Please add the source and a short note about the conditions you used, and if necessary more detailed ones to the Talk page. You can use [http://repo.openpandora.org/?page=detail&app=sysinfo.wb Pandora System Info] to monitor power consumption.

==Battery Care==
* You can charge your [[battery]] to full charge, the charging circuits will then reduce the current to avoid overheating
* If you won't use the [[battery]] for more than a week, it is best to leave it at about 40% charged (as opposed to full)
* Don't worry about running it down too low, there are protection circuits to avoid a '''damagingly low discharge'''.
**Avoid leaving the battery completely discharged though. When the power runs out, the system will be unable to shutdown cleanly, and might corrupt your files or the system.
* No harm will come if you only partially recharge it. If you've only got 10 free minutes to charge before leaving, go ahead. You'll put an hour of usage back into the battery, and you can always charge it more later.
* For best accuracy, the battery meter relies on watching the battery discharge over most of it's range (down to say 10%).
**This will only affect the 'time to run' indication
* If you're not going to be using your battery for a very long time, the extremely best thing you can do for it is to discharge to 40%, seal it in an airtight bag, and put it in the fridge. Even years later, you pull it out, and it will be almost as good as when you put it in.

Urjaman: /* LCD */

{{introNote|About custom hardware extensions, see also [[Kernel interface]]}}
==Official Hackers Manual==
There is a LOT of great information in this:
[http://www.openpandora.org/downloads/PANDORA_Hackers_manual_v101.pdf Pandora Hackers Manual v1.01 by MWeston]

==Pinouts==
Here's a list of pinouts for the various connectors and boards.

Here's a pic of the board, some of the pinouts can be seen on it. [http://pandorapress.net/files/2010/02/rev5.jpg]

==Ext Connector==
[[Image:Cable_connector pinout.png|thumb|TV cable connector]]
''What does it have?''
* UART2
* UART3
* TV out
* Stereo line out
* Stereo line in
* The UART lines can also be used as GPIO (six of them) and PWM lines (four of them).

''Where can we get the connectors from?''

* The connector appears to be a Tyco Electronics connector, part number 1717169-2
* The manufacturer does *not* stock these for engineering samples, and very few vendors carry them
* Community member [http://boards.openpandora.org/index.php?/user/157-wizardstan/ WizardStan] has ordered a bunch and is selling them at $2 a piece plus shipping from Canada, [http://boards.openpandora.org/index.php?/topic/2675-ext-connectors/ see here (thread)] or [http://pandorapress.net/2011/05/18/ext-connectors-have-arrived/ here (article)]

===How Do I Make a TV-Out Cable?===
* There are some useful tips in the [http://boards.openpandora.org/index.php?/topic/2675-ext-connectors/ EXT Connectors] thread.
* A guide explaining one way of creating the video cables can be found [http://dl.openhandhelds.org/cgi-bin/pandora.cgi?0,0,0,0,23,465 here]
* MarkoeZ Has written a blog post about it [http://markoez.pirategames.co.uk/index.php/blog/pandora-ext-tv-out-explained/ here]

==Battery==
[[Image:Battery.jpg|thumb]]
* 3.7V
* Lithium polymer single cell battery

* LTPS (8-bit parallel input for R, G and B, with separate horizontal and vertical sync)
* 3.0V

===UART===
* UART2 and 3 are available via the EXT connector, and via internal solder pads on the latest revision
** UART2 appears to support hardware flow control with RTS/CTS lines
** On the 2.6.27 Kernel UART3 is /dev/ttyS0
** On 2.6.37 or later, UART2 is accessible through /dev/ttyO1, UART3 is on /dev/ttyO2

===GPIO===
* 6 are available on the EXT connector
* 7 are internal, 2 of which can be used as extra shoulder buttons
* 1 located on the LCD cable

===JTAG===
* Yes, 1.8V 10-pin (board label JTAG)

===I<sup>2</sup>C===
* One at 1.8V from the OMAP (board label I2C3-1V8)
* One at 2.8V (board label I2C3-2V8)

=== USB ===
* No internal USB ports

===Keypad backlight===
* ?

===Extra LEDs===
LED7 and LED8 can be added. You need to add FETs (Q17 and Q18) and resistors (R165, R166, R167 and R168)
See the official "Pandora Hacker Guide" from Michael Weston for more details and component values.

==Breakout Board==
[[Image:Breakoutboard.jpg|thumb|alt=Developer's breakout board|Developer's breakout board]]
This is the breakout board used by Pandora team members during development. Only a small number were made, and they are not available to the public. However a similar product (or gerber files) may be released in the future. A schematic for this board is available here: http://openpandora.ca/schematic/AV_Board_schematic.pdf

User:Urjaman/Building the kernel on the Pandora

2012-03-26T02:17:29Z

Urjaman: /* Checkout pandora-kernel */

This is still a WIP set of notes. Testing in progress.
Will add SGX and WiFi module building later.

== Install local toolchain and git ==
Open up a terminal if you havent already. This stuff (opkg) is currently quite dangerous and you might end up breaking your install. I recommend using an SD install for this.
sudo opkg update
This is untested and IIRC I needed to fiddle with the names a bit.
You can "search" for a name with eg. with sudo opkg list | grep name
sudo opkg install gcc gcc-symlinks make binutils-dev cpp cpp-symlinks g++ \
g++-symlinks libstdc++-dev git u-boot-mkimage
Note: I did this 26.3.2012 and I needed to add --force to this opkg, and it slightly broke the install; before rebooting do this (be root before the opkg, skip the sudo) to atleast somewhat fix it:
cd /usr/lib
ln -s libncursesw.so.5 libncurses.so.5

== Get ext2 space ==
=== Choose from ===
==== I run my OS from SD ====
Make a directory in your home folder then:
mkdir dev && cd dev
==== I have an ext2 formatted SD card ====
Make a directory on the card then:
cd /media/<ext2card>
mkdir dev && cd dev
==== I only have a FAT32 formatted SD card ====
Then you can create an ext2 loop file (1GiB) on the card:
cd /media/<fatcard>
dd if=/dev/zero of=dev.ext2 bs=1M count=1024
mke2fs -m 0 dev.ext2
mkdir dev
sudo mount -o loop dev.ext2 dev
cd dev
You should now be in a folder named "dev" suitable for the job.

== Checkout pandora-kernel ==
git clone --depth=1 git://git.openpandora.org/pandora-kernel.git
cd pandora-kernel && git checkout --track -b pandora-27-omap1 origin/pandora-27-omap1 && cd ..
This will take a moment. Go grab your chosen beverage.

== Fix Makefile ==
This gem is from vminko's ebuild.
It will remove the cross-compiling prefix from the Makefile, so that it will use gcc instead of arm-linux-gcc.

== Configure kernel ==
cp ../openpandora.oe/recipes/linux/omap3-pandora-kernel/defconfig .config
make oldconfig

== Fix Makefile ==
This gem is from vminko's ebuild.
It will remove the cross-compiling prefix from the Makefile, so that it will use gcc instead of arm-linux-gcc.
sed -i 's/?= arm-linux-/=/' Makefile

== Configure kernel ==
cp ../openpandora.oe/recipes/linux/omap3-pandora-kernel/defconfig .config
make oldconfig
if you want to change configuration:
make menuconfig
You will need to change the configuration if you want the kernel name to match stock, disable General Setup -> Automatically append version information to the version string .

== Build the kernel ==
This will take time and CPU power, so if you're like me, dont forget to overclock.

Modules, if desired:
make modules
and the kernel:
make uImage
if you want to install modules:
sudo make modules_install

Urjaman: /* I only have a FAT32 formatted SD card */

This is still a WIP set of notes. Testing in progress.
Will add SGX and WiFi module building later.

== Install local toolchain and git ==
Open up a terminal if you havent already.
sudo opkg update
This is untested and IIRC I needed to fiddle with the names a bit.
You can "search" for a name with eg. with sudo opkg list | grep name
sudo opkg install gcc gcc-symlinks make binutils-dev cpp cpp-symlinks g++ \
g++-symlinks libstdc++-dev git u-boot-mkimage

== Get ext2 space ==
=== Choose from ===
==== I run my OS from SD ====
Make a directory in your home folder then:
mkdir dev && cd dev
==== I have an ext2 formatted SD card ====
Make a directory on the card then:
cd /media/<ext2card>
mkdir dev && cd dev
==== I only have a FAT32 formatted SD card ====
Then you can create an ext2 loop file (1GiB) on the card:
cd /media/<fatcard>
dd if=/dev/zero of=dev.ext2 bs=1M count=1024
mke2fs -m 0 dev.ext2
mkdir dev
sudo mount -o loop dev.ext2 dev
cd dev
You should now be in a folder named "dev" suitable for the job.

This is still a WIP set of notes. Testing in progress.
Will add SGX and WiFi module building later.

== Open up a terminal ==
You should not need help with this.

== Install local toolchain and git ==
sudo opkg update
This is untested and IIRC I needed to fiddle with the names a bit.
You can "search" for a name with eg. with sudo opkg list | grep name
sudo opkg install gcc gcc-symlinks make binutils-dev cpp cpp-symlinks g++ g++-symlinks libstdc++-dev git

== Get ext2 space ==
=== Choose from ===
==== root in SD ====
mkdir dev && cd dev
==== ext2 formatted SD card ====
cd /media/<ext2card>
mkdir dev && cd dev
==== ext2 loop file (1GiB) on an SD card ====
cd /media/<fatcard>
dd if=/dev/zero of=dev.ext2 bs=1M count=1024
mke2fs -m 0 dev.ext2
mkdir dev
sudo mount -o loop dev.ext2 dev
cd dev
You should now be in a folder named "dev" suitable for the job.

== Checkout pandora-kernel ==
git clone --depth=1 git://git.openpandora.org/pandora-kernel.git
This will take a moment. Go grab your chosen beverage.

== Checkout and apply patches ==
git clone --depth=1 git://git.openpandora.org/openpandora.oe.git
cd pandora-kernel
Here cross-ref against ../openpandora.oe/recipes/linux/omap3-pandora-kernel_2.6.27-pandora.bb wont hurt.

== Fix Makefile ==
This gem is from vminko's ebuild
sed -i 's/?= arm-linux-/=/' Makefile

== Configure kernel ==
cp ../openpandora.oe/recipes/linux/omap3-pandora-kernel/defconfig .config
make oldconfig
if you want to change configuration:
make menuconfig
You will need to change the configuration if you want the kernel name to match stock, disable General Setup -> Automatically append version information to the version string .

== Build the kernel ==
This will take time and CPU power, so if you're like me, dont forget to overclock.
Modules, if desired:
make modules
and the kernel:
make uImage
if you want to install modules:
sudo make modules_install

Urjaman: Initial WIP draft of my pandora kernel building Howto

Building the kernel on the Pandora

This is still a WIP set of notes. Wikification in progress.

0. Open up a terminal
1. Install local toolchain and git
sudo opkg update
# This is untested and IIRC I needed to fiddle with the names a bit.
# You can "search" for a name with eg. with sudo opkg list | grep name
sudo opkg install gcc gcc-symlinks make binutils-dev cpp cpp-symlinks g++ g++-symlinks libstdc++-dev git

2. Get ext2 space
2.1 Choose from (pick one of):
2.1.1 root in SD
mkdir dev && cd dev
2.1.2 ext2 formatted SD card
cd /media/<ext2card>
mkdir dev && cd dev
2.1.3 ext2 loop file (1GiB) on an SD card:
cd /media/<fatcard>
dd if=/dev/zero of=dev.ext2 bs=1M count=1024
mke2fs -m 0 dev.ext2
mkdir dev
sudo mount -o loop dev.ext2 dev
2.2 You should now be in a folder named "dev" suitable for the job.

3. Checkout pandora-kernel
