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.

 * All Bx C2/3/4 Boards should upgrade there MLO from here: Upgrade X-loader and U-boot


 * Recent U-Boot (2010.03-rc1)
 * u-boot.bin from here: http://www.angstrom-distribution.org/beagleboard-demo-image-available
 * Or this one I've archived: Upgrade X-loader and U-boot
 * Version 2009.01 (factory installed on C2/3's) and earlier will not work with this guide
 * Version 2009.11-rc1-00601-g3aa4b51 (factory installed on C4's) should be upgraded
 * 'mmc init' change

= NetInstall =

This is a new section for Lucid, slated for release April 29th

Note: Rootstock in Lucid is broken.. Bug 532733 so the NetInstall is going to be the perfered method for anything over a minimal image.

Official Ubuntu Kernel
Directions: BeagleNetInstall

Community Kernel
Note: Still working on a couple details...

https://code.launchpad.net/~beagleboard-kernel/+junk/debian-di bzr branch lp:~beagleboard-kernel/+junk/debian-di cd debian-dl ./mk_mmc.sh --mmc /dev/sdX --distro lucid --firmware


 * Options:
 * --distro : lucid, sid, squeeze
 * --firmware : installs firmware
 * --serial-mode : force debian-installer uses Serial Port, other wise it'll use the DVI

Finish Install, then reboot...

On first boot with NEWLY created image, stop U-boot, clear NAND: (Bug :)

nand erase 260000 20000 reset

= 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 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 Feb 2010). Therefore it is listed here as 'testing'. (armv7 optimized)

Build Image
rootstock is Ubuntu's new name for Oliver's depreciated build-arm-rootfs script.

Note: Lucid & Proxy Support is currently in bzr trunk and will release with lucid...

rootstock installation
Note: Use latest debootstrap, if the one posted here is no longer available.

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

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 uImage for U-Boot
U-Boot needs a compatible kernel image to boot. To do this, we are using mkimage from (uboot-mkimage) to create an image from the vmlinuz kernel file.

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

Create U-Boot boot image
The version of U-Boot installed or recommended to install uses boot scripts by default. This allows users to easily switch between multiple SD cards with different OS's with different parameters installed. Ubuntu/Debian requires a slight modification to the bootargs line vs. Angstrom, 'ro' vs 'rw'.

Add/Edit 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

Note: If you created an ext2 root filesystem then change "ext3" above to "ext2"

Use mkimage create to actual *.scr file for U-Boot:

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

Copy uImage and boot.scr
Mount your SD card fat32 partition (assuming /dev/sdX1) and copy the uImage and boot.scr to the first partition.

Note: if your system automounts the mmc card, just issue "sudo umount /dev/sdX1 && sudo umount /dev/sdX2"

mkdir -p ./tmp sudo mount /dev/sdX1 ./tmp sudo cp ./uImage ./tmp/uImage Beagle: sudo cp ./ubuntu.scr ./tmp/boot.scr IGEPv2: sudo cp ./ubuntu.scr ./tmp/boot.ini sudo umount ./tmp

Copy the Ubuntu rootfs
Mount your SD card's ext3 partition (assuming /dev/sdX2) and 'untar' the rootfs into it.

mkdir -p ./tmp sudo mount /dev/sdX2 ./tmp sudo tar xfp armel-rootfs-*.tgz -C ./tmp sudo umount ./tmp

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] 0x000031 = { preen_ok = true preen_nomessage = true } 0x000032 = { preen_ok = true preen_nomessage = true }
 * 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

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.

You should be presented with a x-window login screen. If you logged into X windows but do not get a full desktop with window management then execute the command "x-session-manager" at the terminal.

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

or: sudo ifconfig -a sudo dhclient ethX

Additional Network Setup Information can be found HERE

= Advanced =

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/v2.6.32.7-x7.1/ wget http://rcn-ee.net/deb/kernel/beagle/karmic/v2.6.32.7-x7.1/install-me.sh sudo /bin/bash install-me.sh

Note: vmlinuz symbolic link (yes  no)...

Reboot with your new uImage

Upgrade X-loader and U-boot
Compatible with Bx,C2/3/4

Requires MMC card..

bzr branch lp:~beagleboard-kernel/+junk/omap-flasher cd omap-flasher ./mk_mmc.sh --mmc /dev/sdX

1: Place MMC card in Beagle 2: Push/Hold User Button 3: Apply Power 4: After U-boot loads, let off User Button 5: Wait for Flashing to end 6: Power down, remove/edit boot.scr from MMC card

Depending on what's in NAND, you might still have to stop and do this:

nand erase 260000 20000 reset

SGX Video Acceleration
Use a "corporate email" and download the latest (3.01.00.02): http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/gfxsdk/latest/index_FDS.html

Kernel Modules
An older version of these instructions was adapted for the IGEPv2 platform - if you are following this tutorial and have an IGEPv2, consider using http://wiki.jmaustin.org/wiki/IgepSGXUbuntu instead

Use the "build_sgx_module.sh" script in 2.6-stable, module source is now in the *.bin

https://code.launchpad.net/~beagleboard-kernel/+junk/2.6-stable

Directions: bzr branch lp:~beagleboard-kernel/+junk/2.6-stable cd 2.6-stable . build_kernel.sh . build_sgx_modules.sh

Copy uImage and modules from the deploy directory to your SD card.

Copy the GFX_Linux_SDK.tar.gz examples to either your SD card or another media (large file) then boot your omap board.

Run depmod: sudo depmod -a omaplfb

Tweak 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

Startup Script
For 3.01.00.02

Copy /opt/pvr/pvr script:

Jaunty: sudo cp /opt/pvr/pvr /etc/rcS.d/S60pvr.sh sudo chmod +x /etc/rcS.d/S60pvr.sh

Karmic: sudo cp /opt/pvr/pvr /etc/init.d/pvr sudo chmod +x /etc/init.d/pvr sudo update-rc.d pvr defaults

Note, if your updating.. cat /opt/pvr/pvr | sudo tee /etc/init.d/pvr > /dev/null

Test SGX with a DEMO
In GFX_Linux_SDK: cd OGLES/SDKPackage/Binaries/CommonX11/Demos/ChameleonMan ./OGLESChameleonMan

Trouble Shooting
sudo rm /etc/powervr-esrev sudo depmod -a omaplfb sudo /etc/init.d/pvr restart

DSP
This is still a major work in progress...

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.
