BeagleBoardUbuntu
This page is about running a (ARM EABI) Ubuntu distribution at BeagleBoard. BeagleBoard will boot the (ARM EABI) Ubuntu distribution from SD card.
Note: for the best experience, make sure you have an LCD attached to the HDMI port, 2GB/4GB/8GB SD card, and a known good usb2.0 hub with mouse and keyboard.

Before you start, the following issues are known:
- 2.6.29-oer* USB still flaky on the RevC ehci port.. --RobertCNelson 18:17, 6 May 2009 (UTC)
Help
If you need any help:
- Kernel related help:
- #beagle: Beagle irc on freenode, accessible also by web interface (logs)
- Email beagleboard user groups
- Launchpad Project "Beagleboard Kernel"
- trac/svn interface for the kernel builds
- Ubuntu related help:
- #ubuntu-arm: Ubuntu's arm irc on freenode (logs -> year -> month -> day -> #ubuntu-arm.html)
- 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
- RevC2/3 Boards are fine and do not need an upgrade
- Old RevB Boards should upgrade there MLO from here: http://www.angstrom-distribution.org/beagleboard-demo-image-available
- Recent U-Boot with 'boot.scr' scripts enabled
- u-boot.bin from here: http://www.angstrom-distribution.org/beagleboard-demo-image-available
- Or this one I've archived: U-Boot 2009.08+r37 Upgrade
- Version 2009.01 (factory installed on C2/3's) and earlier will not work with this guide
Ubuntu Rootfs Install
This section describes how you create a Ubuntu root file system for your BeagleBoard.
Note:
- Jaunty, aka Ubuntu 9.04, is the recent old-stable version (armv5 optimized)
- Karmic, aka Ubuntu 9.10, is the recent stable version (armv6 optimized)
- Lucid, aka Ubuntu 10.04 is the upcoming Ubuntu version, not released yet (in Nov 2009). Therefore it is listed here as 'testing'. (armv7 optimized)
Development PC: Root File System
Build Image
rootstock is Ubuntu's new name for Oliver's <ogra> depreciated build-arm-rootfs script.
Note: Use latest debootstrap, if the one posted here is no longer available.
Requirements:
Jaunty (9.04) and Debian:
sudo apt-get install qemu wget http://ports.ubuntu.com/pool/main/d/debootstrap/debootstrap_1.0.20~jaunty1_all.deb sudo dpkg -i debootstrap_1.0.20~jaunty1_all.deb wget http://launchpad.net/project-rootstock/trunk/0.1/+download/rootstock-0.1.3.tar.gz tar xf rootstock-0.1.3.tar.gz cd rootstock-0.1.3
Karmic (9.10)
sudo apt-get install rootstock
Note: For USB WIFI adapters, add package "linux-firmware, wireless-tools" to the --seed WiFi Hints: http://elinux.org/BeagleBoardUbuntuNetwork
Rootstock Command line:
sudo ./rootstock --fqdn <hostname> --login <rootuser> --password <rootuserpasswd> --imagesize <qemu image size> --seed <packages> --dist <jaunty/karmic> --serial <ttySx> --kernel-image <http>
Basic Jaunty (9.04) Beagleboard xfce4 image:
sudo ./rootstock --fqdn beagleboard --login ubuntu --password temppwd --imagesize 2G --seed xfce4,gdm --dist jaunty \ --serial ttyS2 --kernel-image http://rcn-ee.net/deb/kernel/beagle/jaunty/v2.6.29-58cf2f1-oer44.1/linux-image-2.6.29-oer44.1_1.0jaunty_armel.deb
Basic Karmic (9.10) Beagleboard xfce4 image:
sudo ./rootstock --fqdn beagleboard --login ubuntu --password temppwd --imagesize 2G --seed xfce4,gdm --dist karmic \ --serial ttyS2 --kernel-image http://rcn-ee.net/deb/kernel/beagle/karmic/v2.6.31.6-x6.0/linux-image-2.6.31.6-x6.0_1.0karmic_armel.deb
Upon Completion, you should have:
armel-rootfs-<date>.tgz -> Root file System, dump to ext2/3 partition of SD card vmlinuz-2.6.<version> -> Boot Image, use mkimage to create uImage and dump to the first fat16 partition of SD card

History

Development PC: Format SD Card
You will need a 1GB SD card or greater.
Standard Console System : ~286MB + Desktop environment (lxde,gdm) : ~479MB
Starting with an empty SD card and using gparted, create:
50 MiB Primary Partition, fat16/fat32 Rest as ext2/ext3
Gparted Example: http://nishanthmenon.blogspot.com/2008/08/how-to-boot-beagle.html
For Reference:
Disk /dev/sdd: 2038 MB, 2038431744 bytes 255 heads, 63 sectors/track, 247 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x0008e471 Device Boot Start End Blocks Id System /dev/sdd1 1 6 48163+ 6 FAT16 /dev/sdd2 7 247 1935832+ 83 Linux
Development PC: Setup SD Partition's
Requirements:
sudo apt-get install uboot-mkimage
Create U-boot compatible uImage (execute command from within the directory holding your downloaded images):
mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008000 -n "Linux" -d ./vmlinuz-* ./uImage
Create U-boot boot script:
ubuntu.cmd:
setenv bootcmd 'mmc init; fatload mmc 0:1 0x80300000 uImage; bootm 0x80300000' setenv bootargs 'console=ttyS2,115200n8 console=tty0 root=/dev/mmcblk0p2 rootwait rootfstype=ext3 ro vram=12M omapfb.mode=dvi:1280x720MR-16@60' boot
Note: If you created an ext2 root filesystem then change "ext3" above to "ext2"
Create U-boot *.scr file:
mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n "Ubuntu 9.10" -d ./ubuntu.cmd ./ubuntu.scr
Mount your SD card fat32 partition (assuming /dev/sdX1) and copy the uImage to the first partition.
Note: if your system automounts the mmc card, just issue "sudo umount /dev/sdX1 && sudo umount /dev/sdX2"
mkdir ./tmp sudo mount /dev/sdX1 ./tmp sudo cp ./uImage ./tmp/uImage sudo cp ./ubuntu.scr ./tmp/boot.scr sudo umount ./tmp
Mount your SD card's ext3 partition (assuming /dev/sdX2) and 'untar' the rootfs into it.
sudo mount /dev/sdX2 ./tmp sudo tar xfp armel-rootfs-[date].tgz -C ./tmp sudo umount ./tmp
Karmic: (9.10) boot fixup
util-linux-ng 2.16 causes this
Edit /etc/fstab
sudo mount /dev/sdX2 ./tmp sudo gedit ./tmp/etc/fstab add: /dev/mmcblk0p2 / ext3 errors=remount-ro 0 1
Note change the above to "ext3" to "ext2" if the root filesystem is ext2
Add/Edit /etc/e2fsck.conf
sudo gedit ./tmp/etc/e2fsck.conf
[problems] # Superblock last mount time is in the future (PR_0_FUTURE_SB_LAST_MOUNT). 0x000031 = { preen_ok = true preen_nomessage = true } # Superblock last write time is in the future (PR_0_FUTURE_SB_LAST_WRITE). 0x000032 = { preen_ok = true preen_nomessage = true }
Add karmic updates to /etc/apt/sources.list
sudo gedit ./tmp/etc/apt/sources.list
deb http://ports.ubuntu.com/ubuntu-ports karmic-updates main universe
Finally
cd ./tmp sync cd .. sudo umount ./tmp
Development PC or Beagleboard: System Setup on the (ext2/ext3) Partition
Enable Network Access
Modify /etc/network/interfaces

Manual: From the Command line

Install Kernel Image
Script File
Every Kernel upload going further on rcn-ee.net will now have an 'install-me.sh' file in the same directory..
example: http://www.rcn-ee.net/deb/kernel/beagle/karmic/v2.6.31.6-x6.0/ wget http://rcn-ee.net/deb/kernel/beagle/karmic/v2.6.31.6-x6.0/install-me.sh sudo /bin/bash install-me.sh
Note: vmlinuz symbolic link (yes <or> no)...
Reboot with your new uImage
Upgrade U-Boot
Using gparted, create a new 50MB Primary fat32 Partition on a blank SD card, or use your existing fat32 partition.
cd /media/XXXX-XXXX sudo wget http://rcn-ee.net/deb/tools/u-boot-beagleboard-2009.08+r37+gitr1590f84007e2b50ad346a482fff89195cb04ff4e-r37.bin sudo mv u-boot-beagleboard-2009.08+r37+gitr1590f84007e2b50ad346a482fff89195cb04ff4e-r37.bin u-boot.bin
Tested --RobertCNelson 22:18, 2 December 2009 (UTC) RevB5 & RevC2
Insert SD Card, boot Beagleboard and stop U-Boot from booting
mmc init (or if an old u-boot) mmcinit fatload mmc 0:1 0x80300000 u-boot.bin nand unlock (old command, removed in later u-boot's) nandecc sw nand erase 80000 160000 nand write 0x80300000 80000 160000 nand erase 260000 20000 (Clear old U-boot environment, this enables 'boot.scr' scripts) reset
Tested --Dingo_aus 5 December 2009 - C3 factory 2009.1 uses "mmc init" not "mmcinit" and no need for "nand unlock"
SGX Video Acceleration
Kernel Modules
The 'install-me.sh' script will download and install these, however make sure to issue this command to update the omaplfb modules.
sudo depmod -a omaplfb
SDK
Make sure to use a "corporate email" : http://software-dl.ti.com/dsps/forms/export.html?prod_no=/OMAP35x_Graphics_SDK_setuplinux_3_00_00_09.bin
Note: the SDK will not extract directly on any arm platform, extract it first on an x86 machine and tar the resulting folder before transferring to the beagleboard.
System Libraries:
sudo ln -sf /usr/lib/libXdmcp.so.6.0.0 /usr/lib/libXdmcp.so.0 sudo ln -sf /usr/lib/libXau.so.6.0.0 /usr/lib/libXau.so.0

Xorg omapfb Drivers
By default Ubuntu 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.
