<p>Parrishcartwright: </p> <hr /> <div>=Pin functions (mux)=<br /> Currently this needs recompiling u-boot, but some easier control is planned.<br /> <br /> By default UART2 pins are set up as GPIOs, and UART3 as an UART.<br /> <br /> =Power supply=<br /> Currently requires patching bootloaders (xload and u-boot).<br /> <br /> This is connected to VAUX3 supply on PMIC, with these programmable voltages (200mA max):<br /> 1.5V, 1.8V, 2.5V, 2.8V and 3.0V, with 2.8V as default.<br /> <br /> '''warning''': at the time of this writing, both bootloaders (xload and u-boot) set this to 2.8V, so don't rely on this providing other voltages during reboot until you patch both bootloaders.<br /> <br /> =GPIOs=<br /> Can be controlled using GPIO sysfs class device, as described in beagleboard tutorials [http://bbfordummies.blogspot.com/2009/07/1.html here].<br /> <br /> =UART3=<br /> By default, kernel messages are directed there and a terminal with a shell is attached. The port runs at 115200 8N1 baud rate.<br /> ==Disabling kernel messages==<br /> To disable kernel mesages, you need to edit kernel boot arguments. Probably easiest way to do it is to create autoboot.txt and place on root directory of a card in slot1 with this content:<br /> &lt;source lang=&quot;bash&quot;&gt;<br /> setenv bootargs ubi.mtd=4 ubi.mtd=3 root=ubi0:rootfs rootfstype=ubifs rw rootflags=bulk_read<br /> &lt;/source&gt;<br /> Alternatives are using u-boot environment (configure through USB or UART3 serial before system boots up) or patching and reflashing u-boot itself.<br /> ==Disabling attached terminal==<br /> For this you need to edit /etc/inittab on pandora rootfs and comment out this line:<br /> &lt;source lang=&quot;bash&quot;&gt;<br /> #S:2345:respawn:/sbin/getty 115200 ttyS0<br /> &lt;/source&gt;<br /> <br /> [http://writing-help.org/ essay writing help]</div>
