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.

Ubuntu Rootfs Install

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

PC: Built Root file system

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 ./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 2G --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

PC: Setup SD ext2/ext3 Partition

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

cd /media/disk/
* (i modified Oliver's script so it's running as his now to complete this section)
*
sudo tar x(j)fp armel*.tar.* -C /media/disk
*
*

Beagleboard

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

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
