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.

= Known issues =

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"
 * Launchpad Stable Kernel 2.6.29 src
 * Launchpad Development Kernel 2.6.31 src
 * Launchpad Kernel git src
 * Launchpad Kernel for Ubuntu Lucid (10.04)
 * 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)

= Recommended Beagle Software =


 * Use recent xloader: If you start from SD card, download MLO_revc_v3 and rename it to MLO before putting in on SD card.


 * U-Boot 2009.03+r22 Upgrade

Warning note: RevB board + RevC Validation U-boot + 2.6.29-oer30 = NO USB (USB worked fine with 2.6.28)

= 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
 * Karmic, aka Ubuntu 9.10, is the recent stable version
 * Lucid, aka Ubuntu 10.04 is the upcoming Ubuntu version, not released yet (in Nov 2009). Therefore it is listed here as 'testing'.

Build Image
rootstock is Ubuntu's new name for Oliver's 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 --login --password --imagesize --seed --dist  --serial  --kernel-image

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/v2.6.31.5-x5.3/linux-image-2.6.31.5-x5.3_1.0karmic_armel.deb

Upon Completion, you should have: armel-rootfs- .tgz -> Root file System, dump to ext2/3 partition of SD card vmlinuz-2.6. -> Boot Image, use mkimage to create uImage and dump to the first fat16 partition of SD card

History 1.1 - Switched to 2.6.31.6 based kernel

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:

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

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 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

Add/Edit /etc/e2fsck.conf sudo gedit ./tmp/etc/e2fsck.conf

 * 1) Superblock last mount time is in the future (PR_0_FUTURE_SB_LAST_MOUNT).
 * 1) Superblock last write time is in the future (PR_0_FUTURE_SB_LAST_WRITE).

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

Enable Network Access
Modify /etc/network/interfaces auto eth0 iface eth0 inet dhcp

Manual: From the Command line sudo ifconfig eth0 up sudo dhclient eth0

Beagleboard: Setup U-boot for boot
Using a terminal program, such as minicom or gtkterm stop u-boot and add these commands:

Note: if you copy/paste with minicom these commands may end up cut off.

For Linux Kernel 2.6.29 and higher using DSS2 setenv bootcmd 'mmcinit; fatload mmc 0:1 0x80300000 uImage; bootm 0x80300000' or setenv bootcmd 'mmc init; fatload mmc 0:1 0x80300000 uImage; bootm 0x80300000' (r27) setenv bootargs 'console=ttyS2,115200n8 console=tty0 root=/dev/mmcblk0p2 rootwait rootfstype=ext3 ro omapfb.mode=dvi:1280x720MR-16@60' saveenv boot

You shall adapt the resolution to you screen as following : omapfb.mode=dvi:1280x720MR-16@60 Modes: "1024x768MR-16@60""800x600MR-16@60" ...

Script File
Note: this will be updated from time to time. (tested off course, may need "sudo apt-get install wget")

wget http://www.rcn-ee.net/deb/kernel/ubuntu-update-kernel.sh sudo /bin/bash ubuntu-update-kernel.sh

Note: vmlinuz symbolic link (yes  no)... Still not sure this matters, i select ...

Manual Method
You can open/edit the ubuntu-update-kernel.sh to see latest version.

sudo apt-get install uboot-mkimage wget http://www.rcn-ee.net/deb/kernel/beagle/jaunty/v2.6.29-58cf2f1-oer44.1/linux-image-2.6.29-oer44.1_1.0jaunty_armel.deb (or any listed here: http://www.rcn-ee.net/deb/kernel/beagle/jaunty/ ) sudo dpkg -i linux-image*

Extract linux-image's vmlinuz-* (we need this to create the uImage, uboot uses to boot) 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

unmount fat32 partition sudo umount /mnt

Clean up rm -rfd temp

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.

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.
