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
 * Beagle Ubuntu 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)

= 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 stable version
 * Karmic, aka Ubuntu 9.10, is the upcoming Ubuntu version, not released yet (in August 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: sudo apt-get install qemu

wget http://ports.ubuntu.com/pool/main/d/debootstrap/debootstrap_1.0.13~jaunty1_all.deb sudo dpkg -i debootstrap_1.0.13~jaunty1_all.deb

Karmic (9.10) sudo apt-get install rootstock

Jaunty (9.04), Debian wget http://code.launchpad.net/project-rootstock/trunk/0.1/+download/rootstock-0.1.1.tar.gz tar xf rootstock-0.1.1.tar.gz cd rootstock-0.1.1

Note: For USB WIFI adapters, add package "linux-firmware, wireless-tools" to the --seed WiFi Hints: http://elinux.org/BeagleBoardUbuntuNetwork

General Jaunty Image 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-oer40.5/linux-image-2.6.29-oer40.5_1.0jaunty_armel.deb

Upon Completion, you should have: armel-rootfs- .tgz vmlinuz-2.6.

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, fat32 Rest as ext2/ext3

Gparted Example: http://nishanthmenon.blogspot.com/2008/08/how-to-boot-beagle.html

Development PC: Setup SD uboot/uImage Partition
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. (/media/disk/) and copy the uImage to the first partition.

cd /media/disk sudo cp .//uImage uImage

Development PC: Setup SD ext2/ext3 Partition
Mount your SD ext2/ext3 partition. (/media/disk/)

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

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, stop u-boot and add these commands:

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-oer40.5/linux-image-2.6.29-oer40.5_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.

cd /media/disk sudo wget http://www.rcn-ee.net/deb/tools/u-boot-beagleboard-2009.05+r27+gitrd363f9cb0918a1b6b92e2e20d01543d0c4f53274-r27.bin sudo mv u-boot-beagleboard-2009.05+r27+gitrd363f9cb0918a1b6b92e2e20d01543d0c4f53274-r27.bin u-boot-f.bin
