BeagleBoardDebian

This page is about running a (ARM EABI) Debian distribution at BeagleBoard. BeagleBoard will boot the (ARM EABI) Debian distribution from SD card. Debian's NetInstall will be used to install Debian onto your Beagle.

Note: Debian armel deb's are compiled for armv4t, this allows debian to support a larger number of arm devices with a single port, at only the sacrifice of speed.

= Help =

If you need any help:


 * Kernel related help:
 * Email Beagleboard user group *Recommended method
 * #beagle: Beagle irc on freenode, accessible also by web interface (logs)
 * Launchpad Project "Beagleboard Kernel"
 * Launchpad Stable Kernel 2.6.32 src
 * Launchpad Development Kernel 2.6.32 src
 * Launchpad Mainline Kernel git src *Unless you know what your doing, do NOT use the 2.6-mainline branch...
 * Kernel Testing Results


 * When asking for help, please provide some debugging information:
 * U-Boot Version installed on board
 * Kernel Version: uname -a
 * pastebin dmesg
 * Copy from serial port or use "dmesg | pastebinit" (sudo apt-get install pastebinit)

= Recommended Beagle Software =
 * Recent x-loader/MLO (1.4.4ss)
 * All Bx C2/3/4 Boards should upgrade there MLO from here: Upgrade X-loader and U-boot


 * Recent U-Boot (2010.03-rc1)
 * u-boot.bin from here: http://www.angstrom-distribution.org/beagleboard-demo-image-available
 * Or this one I've archived: Upgrade X-loader and U-boot
 * Version 2009.01 (factory installed on C2/3's) and earlier will not work with this guide
 * Version 2009.11-rc1-00601-g3aa4b51 (factory installed on C4's) should be upgraded
 * 'mmc init' change

Development PC: Format SD Card
Planning to remove this section, pending Squeeze's Release...

You will need a 1GB SD card or greater. Standard System : ~455MB + Desktop environment (GNOME) : ~2.9GB

Starting with an empty SD card and using gparted, create: 50 MiB Primary Partition, fat32 Leave remaining space for the Debian-Installer

Development PC: Setup SD U-boot Partition
Mount your SD card fat32 partition. (/media/disk/)

Debian Lenny
cd /media/disk/ sudo wget http://rcn-ee.net/deb/kernel/CC-beagle-v2.6.29-58cf2f1-oer44.1.uImage sudo wget http://ftp.debian.org/debian/dists/lenny/main/installer-armel/current/images/versatile/netboot/initrd.gz sudo mv CC-beagle-v2.6.29-58cf2f1-oer44.1.uImage uImage sudo gzip -d initrd.gz sudo dd if=initrd of=initrd.pad ibs=8388608 conv=sync

Create U-boot boot script for netinstall:

Debian Install over DVI Port sudo nano netinstall.cmd setenv bootcmd 'mmc init; fatload mmc 0:1 0x80300000 uImage; fatload mmc 0:1 0x81600000 initrd.pad; bootm 0x80300000' setenv bootargs 'console=tty0 ramdisk_size=8192 root=/dev/ram0 rw rootfstype=ext2 initrd=0x81600000,8M omapfb.mode=dvi:1280x720MR-16@60' boot

Debian Install over the Serial Port sudo nano netinstall.cmd setenv bootcmd 'mmc init; fatload mmc 0:1 0x80300000 uImage; fatload mmc 0:1 0x81600000 initrd.pad; bootm 0x80300000' setenv bootargs 'console=ttyS2,115200n8 ramdisk_size=8192 root=/dev/ram0 rw rootfstype=ext2 initrd=0x81600000,8M' boot

Create U-boot *.scr file:

sudo mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n "Debian Lenny" -d ./netinstall.cmd ./boot.scr

Sync and Unmount your mmc card and boot the beagle, it should find the 'boot.scr' file on your first partition while booting.

Debian Squeeze
(Testing Release Summer 2010?)

Note: Squeeze hasn't been released, so if you get an error, retry in a couple hours..

https://code.launchpad.net/~beagleboard-kernel/+junk/debian-di bzr branch lp:~beagleboard-kernel/+junk/debian-di cd debian-di ./mk_mmc.sh --mmc /dev/sdX --distro squeeze --firmware


 * Options:
 * --distro : squeeze, lucid
 * --firmware : installs firmware
 * --serial-mode : debian-installer uses Serial Port

Note: The default options work for most people, but if you'd like to tweak boot settings, edit these before running the script. NetInstall boot Settings: gedit ./debian-di/scripts/dvi.cmd gedit ./debian-di/scripts/serial.cmd Normal Boot Settings: gedit ./debian-di/scripts/dvi-normal-squeeze.cmd gedit ./debian-di/scripts/serial-normal-squeeze.cmd

Beagleboard: NetInstall
Choose a language C - No localization English - English

Configure the network: usb0: USB net <- See below for 2.6.29. Could not find usb0 with B7 installing 2.6.28. eth0: Ethernet <- Your usb-ethernet device wlan0: Wifi <- Your usb-wifi device.. See BeagleBoardDebianWifiInstallInfo for my hack to set it up.

usb0 howto
There's a lot of question on irc about this, it might make sense to add a wiki page going thru with linux/winxp etc.. --RobertCNelson 00:55, 23 April 2010 (UTC)

Configuring usb0 network bridge for 2.6.29: While you chose your keyboard layout, setup a bridge with ethX and usbX. # ifconfig ethX 0.0.0.0 # ifconfig usbX 0.0.0.0 # brctl addbr brX # brctl addif brX ethX # brctl addif brX usbX # ifconfig brX up  # dhclient brX *Sometimes the first beagle DHCP will fail(probably due PC trying autoconnect), just run the auto configuration again and it will configure it right.

Development PC: Setup U-boot for Normal Boot
Planning to remove this section, pending Squeeze's Release... I moved the relevant data to: http://elinux.org/BeagleBoardDebian#U-boot_Scripts

Create a U-boot normal boot script:

DVI Port sudo nano normal.cmd setenv bootcmd 'mmc init; fatload mmc 0:1 0x80300000 uImage; bootm 0x80300000' setenv bootargs 'console=tty0 root=/dev/mmcblk0p2 rootwait rootfstype=ext3 ro omapfb.mode=dvi:1280x720MR-16@60' boot

Serial Port sudo nano normal.cmd setenv bootcmd 'mmc init; fatload mmc 0:1 0x80300000 uImage; bootm 0x80300000' setenv bootargs 'console=ttyS2,115200n8 root=/dev/mmcblk0p2 rootwait rootfstype=ext3 ro' boot

Create U-boot *.scr file:

sudo mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n "Debian Lenny" -d ./normal.cmd ./boot.scr

Debian will fix the ext3 partition, it'll try to reboot, after halting remove and reapply power.

Beagleboard: Install Latest Kernel
Script File:

Lenny: wget http://rcn-ee.net/deb/kernel/beagle/lenny/v2.6.32.11-x13/install-me.sh sudo /bin/bash install-me.sh Squeeze: wget http://rcn-ee.net/deb/kernel/beagle/squeeze/v2.6.32.11-x13/install-me.sh sudo /bin/bash install-me.sh

U-boot Scripts
Create a U-boot normal boot script:

Serial Port sudo nano normal.cmd setenv bootcmd 'mmc init; fatload mmc 0:1 0x80300000 uImage; bootm 0x80300000' setenv bootargs 'console=ttyS2,115200n8 root=/dev/mmcblk0p2 rootwait rootfstype=ext3 ro' boot

Create U-boot *.scr file:

Debian will fix the ext3 partition, it'll try to reboot, after halting remove and reapply power.

Serial Ports
Lenny

edit /etc/inittab and add: S:2345:respawn:/sbin/getty 115200 ttyS2

For root access over the serial port add ttyS2 to /etc/securetty

WiFi
See BeagleBoard Debian WiFi install info.

SGX Video Acceleration
Use a "corporate email" and download the latest (3.01.00.02): http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/gfxsdk/latest/index_FDS.html

Kernel Modules
Use the "build_sgx_module.sh" script in 2.6-stable, module source is now in the *.bin

https://code.launchpad.net/~beagleboard-kernel/+junk/2.6-stable

Copy the *.uImage and extract the matching *.modules.tar.gz from the deploy directory to your SD card.

Copy the GFX_Linux_SDK.tar.gz examples to either your SD card or another media (large file) then boot your omap board.

Run depmod: sudo depmod -a omaplfb

Trouble Shooting

Xorg omapfb Drivers
By default Debian will try* to use the FBDEV video driver, however for the beagleboard we can take advantage of a more software optimized driver (still not using the sgx video hardware) using the NEON extensions of the Cortex-A8 core.

Lenny might need this xorg.conf, but it's best to use omapfb later in this guide..
