Ubuntu 9.04 Alpha seems to be working quite well so here's a quick doc. Eventually this will probably be moved to ubuntu's wiki...

This page is about running a (ARM EABI) Ubuntu distribution at BeagleBoard. BeagleBoard will boot the (ARM EABI) Ubuntu distribution from SD card.

U-Boot 2009.01 Upgrade: http://elinux.org/BeagleBoardUbuntu#Upgrade_U-Boot

Ubuntu Rootfs Install

Use Oliver's <ogra> script located here: https://wiki.ubuntu.com/ARM/RootfsFromScratch

PC: Built Root file system

Requirements:

sudo apt-get install qemu
wget http://ports.ubuntu.com/pool/main/d/debootstrap/debootstrap_1.0.10ubuntu3_all.deb
sudo dpkg -i debo*
wget http://people.ubuntu.com/~ogra/arm/build-arm-rootfs
sudo chmod u+x build-arm-rootfs 

General

sudo ./build-arm-rootfs --fqdn <hostname> --login <rootuser> --password <rootuserpasswd> --imagesize <qemu image size> --seed <packages>

lxde Destktop

sudo ./build-arm-rootfs --fqdn beagleboard --login ubuntu --password temppwd --imagesize 2G --seed lxde,gdm 

Xubuntu Desktop

sudo ./build-arm-rootfs --fqdn beagleboard --login ubuntu --password temppwd --imagesize 2G --seed xubuntu-desktop

Ubuntu Desktop

sudo ./build-arm-rootfs --fqdn beagleboard --login ubuntu --password temppwd --imagesize 3G --seed ubuntu-desktop

PC: Format SD Card

You will need a 1GB SD card or greater.

Standard System : ~xxxMB
+ Desktop environment (GNOME) : ~x.xGB

Starting with an empty SD card and using gparted, create:

50 MiB Primary Partition, fat32
Rest as ext2/ext3

PC: Setup SD uboot/uImage Partition

Mount your SD card fat32 partition. (/media/disk/)

cd /media/disk/
wget http://www.rcn-ee.com/deb/kernel/CC-v2.6.28-9a6536c-oer8
mv CC-v2.6.28-9a6536c-oer8 uImage
(Set based on partition type, extX = ext2 or ext3)
wget http://www.rcn-ee.com/deb/*****/ubuntu-extX.scr
mv ubuntu-extX.scr boot.scr

PC: Setup SD ext2/ext3 Partition

Mount your SD ext2/ext3 partition. (/media/disk/)

sudo tar xfp armel-rootfs-[date].tgz -C /media/disk

Login & Install kernel-image

cd /home/<user>
sudo apt-get install uboot-mkimage 
wget http://www.rcn-ee.com/deb/kernel/beagle/jaunty/v2.6.28-79d042a-oer10/linux-image-2.6.28-oer10_1.0jaunty_armel.deb
sudo dpkg -i linux-image*

Extract linux-image's vmlinuz-*

dpkg -x linux-image* ./temp

Mount fat32 partition

sudo mount /dev/mmcblk0p1 /mnt

Build uboot compatible image and copy to fat32 boot partition

sudo mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008000 -n "Linux" -d ./temp/boot/vmlinuz-*  /mnt/uImage

Clean up

rm -rfd temp

Sync, umount Partitions and Reboot

Advanced

Upgrade U-Boot

Using gparted, create a new 50MB Primary fat32 Partition on a blank SD card, or use your existing fat32 partition.

wget http://www.angstrom-distribution.org/demo/beagleboard/u-boot.bin
cp u-boot.bin /media/disk

Tested with (U-Boot 2009.01-00013-g52eddcd (Feb 03 2009 - 22:25:11)) Archive: http://rcn-ee.homeip.net:81/dl/omap/uboot/u-boot-beagle-04feb2009.bin

Insert SD Card, boot Beagleboard and stop U-Boot 1.3.x (OR) 2008+

mmcinit
fatload mmc 0 0x80200000 u-boot.bin
nand unlock
nand ecc sw (OR) nandecc sw
nand erase 80000 160000
nand write.i 0x80200000 80000 160000
reset

U-Boot Script Files

mkimage-uboot required

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


Mount SD card

For Kernel 2.6.28 with DSS2
setenv bootcmd 'mmcinit; fatload mmc 0:1 0x80300000 uImage; bootm 0x80300000'
setenv bootargs 'console=ttyS2,115200n8 console=tty0 root=/dev/mmcblk0p2 rootdelay=2 rootfstype=ext3 ro omap-dss.def_disp=lcd omapfb.video_mode=1280x720MR-24@60'
saveenv
boot

Note: rootfstype=extX must match your format of the ext2/ext3 partition
