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:

  • Ubuntu related help:
    • #ubuntu-arm: Ubuntu's arm irc on freenode (logs -> year -> month -> day -> #ubuntu-arm.html)
  • When asking for help, please provide some debugging information:
    • U-Boot Version installed on board
    • Kernel Version: uname -a
    • pastebin dmesg
      • Copy from serial port or use "dmesg | pastebinit" (sudo apt-get install pastebinit)

Recommended Beagle Software

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 (armv5 optimized)
  • Karmic, aka Ubuntu 9.10, is the recent stable version (armv6 optimized)
  • Lucid, aka Ubuntu 10.04 is the upcoming Ubuntu version, not released yet (in Nov 2009). Therefore it is listed here as 'testing'. (armv7 optimized)

Development PC: Root File System

Build Image

rootstock is Ubuntu's new name for Oliver's <ogra> 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 <hostname> --login <rootuser> --password <rootuserpasswd> --imagesize <qemu image size> --seed <packages> --dist <jaunty/karmic> 
 --serial <ttySx>  --kernel-image <http>

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/v2.6.31.6-x6.0/linux-image-2.6.31.6-x6.0_1.0karmic_armel.deb

Upon Completion, you should have:

armel-rootfs-<date>.tgz  -> Root file System, dump to ext2/3 partition of SD card
vmlinuz-2.6.<version>    -> Boot Image, use mkimage to create uImage and dump to the first fat16 partition of SD card

Lucid (10.04) Testing:

Major Changes:

gcc-4.4: https://launchpad.net/ubuntu/lucid/+source/gcc-4.4
 gcc -v: --with-arch=armv7-a --with-tune=cortex-a8 --with-float=softfp --with-fpu=vfpv3-d16

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

Create U-boot boot script:

ubuntu.cmd:

setenv bootcmd 'mmc init; fatload mmc 0:1 0x80300000 uImage; bootm 0x80300000'
setenv bootargs 'console=ttyS2,115200n8 console=tty0 root=/dev/mmcblk0p2 rootwait rootfstype=ext3 ro vram=12M omapfb.mode=dvi:1280x720MR-16@60'
boot

Create U-boot *.scr file:

mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n "Ubuntu 9.10" -d ./ubuntu.cmd ./ubuntu.scr

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 cp ./ubuntu.scr ./tmp/boot.scr
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
[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

Development PC or Beagleboard: System Setup on the (ext2/ext3) Partition

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

Install Kernel Image

Script File

Every Kernel upload going further on rcn-ee.net will now have an 'install-me.sh' file in the same directory..

example: http://www.rcn-ee.net/deb/kernel/beagle/karmic/v2.6.31.6-x6.0/

wget http://rcn-ee.net/deb/kernel/beagle/karmic/v2.6.31.6-x6.0/install-me.sh
sudo /bin/bash install-me.sh

Note: vmlinuz symbolic link (yes <or> no)...

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/XXXX-XXXX
sudo wget http://rcn-ee.net/deb/tools/u-boot-beagleboard-2009.08+r37+gitr1590f84007e2b50ad346a482fff89195cb04ff4e-r37.bin
sudo mv u-boot-beagleboard-2009.08+r37+gitr1590f84007e2b50ad346a482fff89195cb04ff4e-r37.bin u-boot.bin

Tested --RobertCNelson 22:18, 2 December 2009 (UTC) RevB5 & RevC2

Insert SD Card, boot Beagleboard and stop U-Boot from booting

mmc init (or if an old u-boot) mmcinit
fatload mmc 0:1 0x80300000 u-boot.bin
nand unlock  (old command, removed in later u-boot's)
nandecc sw
nand erase 80000 160000
nand write 0x80300000 80000 160000
nand erase 260000 20000   (Clear old U-boot environment, this enables 'boot.scr' scripts)
reset

Tested --Dingo_aus 5 December 2009 - C3 factory 2009.1 uses "mmc init" not "mmcinit" and no need for "nand unlock"

SGX Video Acceleration

Kernel Modules

The 'install-me.sh' script will download and install these, however make sure to issue this command to update the omaplfb modules.

sudo depmod -a omaplfb

SDK

Make sure to use a "corporate email" : http://software-dl.ti.com/dsps/forms/export.html?prod_no=/OMAP35x_Graphics_SDK_setuplinux_3_00_00_09.bin

Note: the SDK will not extract directly on any arm platform, extract it first on an x86 machine and tar the resulting folder before transferring to the beagleboard.

System Libraries:

sudo ln -sf /usr/lib/libXdmcp.so.6.0.0 /usr/lib/libXdmcp.so.0
sudo ln -sf /usr/lib/libXau.so.6.0.0 /usr/lib/libXau.so.0

SDK install lib/bin from 3.00.00.09:

sudo mkdir /usr/lib/ES2.0
sudo mkdir /usr/bin/ES2.0

sudo mkdir /usr/lib/ES3.0
sudo mkdir /usr/bin/ES3.0

sudo cp SDK_EXT_DIR/gfx_rel_es2.x/lib* /usr/lib/ES2.0

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
