This page is about running Ubuntu 9.10 Karmic distribution on the BeagleBoard.
Contents
Demo Image
Karmic 9.10
Built with:
sudo ./rootstock --fqdn beagleboard --login ubuntu --password temppwd --imagesize 2G \ --seed wget,nano,linux-firmware,wireless-tools,usbutils --dist karmic --serial ttyS2 \ --kernel-image http://rcn-ee.net/deb/kernel/beagle/karmic/v2.6.32.11-x13/linux-image-2.6.32.11-x13_1.0karmic_armel.deb
Get prebuilt image:
wget http://rcn-ee.net/deb/rootfs/ubuntu-9.10.2-minimal-armel.tar.7z mirrors: wget http://ynezz.ibawizard.net/beagleboard/ubuntu-9.10.2-minimal-armel.tar.7z wget http://vivaphp.net/beagle/ubuntu-9.10.2-minimal-armel.tar.7z
Unpack it:
7za x ubuntu-9.10.2-minimal-armel.tar.7z tar xf ubuntu-9.10.2-minimal-armel.tar cd ubuntu-9.10.2-minimal-armel
Quick Install script
./setup_sdcard.sh --mmc /dev/sdX --ignore_md5sum
- Bug: --ignore_md5sum is needed
- Additional Options
- --rootfs <ext3 default>
- --swap_file <swap file size in MB's>
md5sum: 0bf198beac0a0358bc2c0097c6dddec7 ubuntu-9.10.2-minimal-armel.tar.7z
RootStock
Karmic: (9.10) boot fixup
util-linux-ng 2.16 causes this
Edit /etc/fstab
mkdir -p ./tmp sudo mount /dev/sdX2 ./tmp sudo gedit ./tmp/etc/fstab add: /dev/mmcblk0p2 / ext3 errors=remount-ro 0 1
Note change the above "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
You can now place the SD card into the BeagleBoard and start up the BeagleBoard.
Please be patient as the first boot can take a couple of minutes.
Advanced
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.
cat /var/log/Xorg.0.log | grep FBDEV
(II) FBDEV: driver for framebuffer: fbdev (II) FBDEV(0): using default device (II) FBDEV(0): Creating default Display subsection in Screen section (==) FBDEV(0): Depth 16, (==) framebuffer bpp 16 (==) FBDEV(0): RGB weight 565
Login into Ubuntu and open a new terminal, xorg has to be running..
