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.

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)

Required Beagle Software

X-loader/MLO (1.4.4ss) & U-Boot (2010.03) (Zippy1 & Zippy2 Support)

  • All Bx, C2/3/4 Boards are required to upgrade to atleast these MLO and U-Boot versions.
  • XM Boards have no NAND, so u-boot.bin is always required on the first partition
  • Directions: Upgrade X-loader and U-Boot

Canonical Pre-Installed Images

Support:

  • #ubuntu-arm: Ubuntu's arm irc on freenode (logs -> year -> month -> day -> #ubuntu-arm.html)

Maverick 10.10

Just follow https://wiki.ubuntu.com/ARM/OMAPMaverickInstall and make sure you're using a SD card >= 4GB.

NetInstall Method

NOTE: Lucid's NetInstall will not work with the new XM model..

The NetInstall Method, allows you to install Ubuntu directly onto your Beagle by pre-populating a boot image that will perform the complete install.

Note: The boot arg's are stored in boot.scr which will be copied to the first partition.

Recommended:

  • 2GB+ SD card
  • USB Ethernet/Wifi

Discover SD/MMC Partition

sudo fdisk -l

Download NetInstall Omap script

git clone git://github.com/RobertCNelson/netinstall-omap.git
cd netinstall-omap
./mk_mmc.sh --mmc /dev/sdX --distro lucid --firmware
  • Options:
    • --distro : lucid
    • --firmware : install firmware for WiFi devices
    • --serial-mode : force NetInstall to use Serial Port

Note: The default boot options work for most people, but if you'd like to tweak boot settings, edit these before running the script.

NetInstall boot Settings:
gedit ./netinstall-omap/scripts/dvi.cmd
gedit ./netinstall-omap/scripts/serial.cmd

Normal Boot Settings:
gedit ./netinstall-omap/scripts/dvi-normal-lucid.cmd
gedit ./netinstall-omap/scripts/serial-normal-lucid.cmd

Place SD card into Beagle and Boot

Troubshooting: If boot fails..

  • Hold the user button down to force booting from MMC
  • Upgrade X-loader and U-boot Upgrade X-loader and U-Boot
  • Clear U-boot's Environment Variables in nand:
nand erase 260000 20000

NetInstall assumptions:

Continue with out Kernel Modules <yes>
Partition <Guided - use the largest continuous free space>

RootStock: Build an Ubuntu root file system

Ubuntu Version's

This guide only covers the latest Ubuntu stable (lucid) release and notes for the testing (lucid+1) dists. Notes for older release's can be found here:

Install RootStock

This is based off Ubuntu's RootStock Project; RootStock script.

Lucid (10.04) (use rootstock trunk)

sudo apt-get install rootstock (to install rootstock's dependices)
bzr branch lp:project-rootstock
cd project-rootstock

Maverick (10.10 beta)

sudo apt-get install rootstock

RootStock

RootStock: Useful seed Packages

Useful Packages:

linux-firmware,wireless-tools :wifi adapters..
ntpdate :sync real time clock from network

GUI's (broken bug: FIXME)

xfce4:  xfce4,gdm,xubuntu-gdm-theme,xubuntu-artwork

RootStock: Running

Rootstock Command line:

sudo ./rootstock --fqdn <hostname> --login <rootuser> --password <rootuserpasswd> --imagesize <qemu image size> \
--seed <packages> --dist <jaunty/karmic/lucid> --serial <ttySx>  --kernel-image <http>

Basic Lucid (10.04) Beagleboard minimal image:

sudo ./rootstock --fqdn beagleboard --login ubuntu --password temppwd --imagesize 2G \
--seed wget,nano,linux-firmware,wireless-tools,usbutils --dist lucid --serial ttyS2 \
--components "main universe multiverse" \
--kernel-image http://rcn-ee.net/deb/lucid/v2.6.33.4-l3/linux-image-2.6.33.4-l3_1.0lucid_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
initrd.img-2.6.<version> -> Boot initramfs, use mkimage to create uInitrd and dump to the first fat16 partition of SD card

Partition 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/ext4/btrfs

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

Copy Root File System to SD Card

Mount your SD card's larger root file system 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

Boot Partition

Requirements:

sudo apt-get install uboot-mkimage

U-Boot uImage

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

U-Boot uInitrd

This step is Optional, but it helps with the lucid and Lucid++ experience.

mkimage -A arm -O linux -T ramdisk -C none -a 0 -e 0 -n initramfs -d ./initrd.img-* ./uInitrd

U-Boot Boot Scripts

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'.

fixrtc: (only uInitrd) Resets RTC based on last mount
buddy=${buddy}: (both) Kernel Zippy1/2 Support
mpurate=${mpurate}: (recommended core clock)

create ubuntu.cmd

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

With optional uInitrd: create ubuntu.cmd:

setenv bootcmd 'mmc init; fatload mmc 0:1 0x80300000 uImage; fatload mmc 0:1 0x81600000 uInitrd; bootm 0x80300000 0x81600000'
setenv bootargs console=tty0 console=ttyS2,115200n8 root=/dev/mmcblk0p2 rootwait ro vram=12M omapfb.mode=dvi:1280x720MR-16@60 fixrtc buddy=${buddy} mpurate=${mpurate}
boot

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 10.04" -d ./ubuntu.cmd ./ubuntu.scr

Copy to Boot Partition

Mount your SD card fat16/fat32 partition (assuming /dev/sdX1) and copy the uImage, boot.scr, and optional uInitrd to the first partition.

mkdir -p ./tmp
sudo mount /dev/sdX1 ./tmp
sudo cp ./uImage ./tmp/uImage
sudo cp ./uInitrd ./tmp/uInitrd

Beagle:
sudo cp ./ubuntu.scr ./tmp/boot.scr

IGEPv2:
sudo cp ./ubuntu.scr ./tmp/boot.ini

sudo umount ./tmp

Install Latest Kernel Image

Script File

Note: this subsection is basically obsolete every time it's modified...

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

But for example: http://rcn-ee.net/deb/lucid/v2.6.34.1-l2/

wget http://rcn-ee.net/deb/lucid/v2.6.34.1-l2/install-me.sh
/bin/bash install-me.sh

Reboot with your new uImage

Upgrade X-loader and U-boot

Compatible with Bx,C2/3/4

Requires MMC card..

git clone git://github.com/RobertCNelson/flash-omap.git
cd flash-omap
./mk_mmc.sh --mmc /dev/sdX (i.e. use /dev/sdc - the entire device, not a partition)
1: Place MMC card in Beagle
2: Push/Hold User Button Down
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

Example 4G card:

sudo fdisk -l
Disk /dev/sde: 3957 MB, 3957325824 bytes
255 heads, 63 sectors/track, 481 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00080e99

   Device Boot      Start         End      Blocks   Id  System

./mk_mmc.sh --mmc /dev/sde

Worst case, depending on what's actually in NAND, you might still have to stop and do this:

nand erase 260000 20000
reset

DSP

This is still a major work in progress...

Here is one approach: BeagleBoard Ubuntu & DSP From Sources

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..

xvinfo -display :0.0

 no adaptors present

Drivers

Note: These are built with neon optimizations: http://git.debian.org/?p=collab-maint/xf86-video-omapfb.git;a=blob;f=debian/rules;h=c2f0d5391c96c5abb60b1e691ad86bb27e0c17d8;hb=HEAD (line 48/49)

Lucid:

sudo apt-get install xserver-xorg-video-omap3

To verify it was correctly installed, reboot and:

cat /var/log/Xorg.0.log | grep omapfb

    etc..

Changing DVI output resolution

Ubuntu 10.10 above defaults to a resolution of 1284x768@16. This is set in the boot.cmd file in the boot partition of the SD card. The change the resolution the DVI outputs, edit boot.cmd accordingly then recreate the boot.scr file by:

mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n "Ubuntu 10.10" -d ./boot.cmd ./boot.scr

Then reboot the BeagleBoard


S-Video

S-video is tested to be working on 2.6.35-rc5-dl9. S-video output can be enabled using bootargs at uboot as mentioned below.

NTSC

    omapfb.mode=tv:ntsc 
    omapdss.def_disp=tv

Bootargs that has been validated.

    setenv bootargs 'console=tty0 console=ttyS2,115200n8 root=/dev/mmcblk0p2 rootwait ro vram=12M omapfb.mode=tv:ntsc omapdss.def_disp=tv 
    fixrtc buddy=unknown'

Note that the NTSC resolution is 640x480. However the edge bands around the TV screen differ from TV to TV. Output of fbset shown below, which does not seem right.

   mode "720x482-30"
        # D: 13.500 MHz, H: 15.734 kHz, V: 29.970 Hz
        geometry 720 482 720 482 32
        timings 74074 16 58 6 31 64 6
        rgba 8/16,8/8,8/0,0/0
   endmode

PAL

Bootargs that has been validated for PAL tv.

    setenv bootargs 'console=tty0 console=ttyS2,115200n8 root=/dev/mmcblk0p2 rootwait ro vram=12M omapfb.mode=tv:pal omapdss.def_disp=tv fixrtc buddy=unknown'

Using these settings video output will display on the tv, however 5-10% of the left and right edges of display are off the screen (using Ubuntu 10.10 with xfce).

xrandr shows the display is set to the minimum of 720x574. Please update wiki if you can fix this.

Ubuntu Software

Wifi Networking (command line)

/etc/network/interfaces

It is possible and relatively easy to configure a wifi card from the command line.

You will need to edit the /etc/network/interfaces file. There are several guides available via Google.

A sample /etc/network/interfaces file for a WPA2 encrypted access point is:

auto lo
iface lo inet loopback
auto wlan0
iface wlan0 inet dhcp
wpa-driver wext
wpa-ssid <NAME OF AP>
wpa-ap-scan 1
wpa-proto RSN
wpa-pairwise CCMP
wpa-group CCMP
wpa-key-mgmt WPA-PSK
wpa-psk < INSERT KEY XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX>

Your wifi card will automatically load these settings on start up and give network access.

Web Apps

Midori

Given that the BeagleBoard has fewer resources than a desktop a light weight browser is more responsive. Midori is a light weight browser that still supports flash etc It is available from the standard repositories. http://en.wikipedia.org/wiki/Midori_%28web_browser%29

Surveillance

Motion

If you have a video source (webcam, IP cam etc) which appears as /dev/video0 etc then you can use the Linux Surveillance software "motion" to monitor the video stream and record periods of activity.

Motion is also available from the standard repositories. http://www.debian-administration.org/article/An_Introduction_to_Video_Surveillance_with_%27Motion%27 Using a 960x720 resolution webcam with 15 fps rate under the UVC driver the Rev C BeagleBoard under Xubuntu reports ~60% CPU utilisation.

To make the BeagleBoard automatically start recording on boot do the following:

  • Auto Login - run "gdmsetup" from a terminal and select a user to automatically login
  • Sessions - make sure you don't save any previous xwindows sessions so that it doesn't prompt you for which one you want
  • motion.conf - amend /etc/motion/motion.conf to the settings you want (ie video output directory, record only video, record in mpeg4, set frame rate etc). Do this with "sudo medit /etc/motion/motion.conf" at a prompt.
  • Boot script - create a new script in /etc/rc2.d called "S65motion_client" and set permissions appropriately ("sudo chmod 777 /etc/rc2.d/S65motion_client"). Then edit the file so it has the following text in it:
#! /bin/sh
/usr/bin/motion -c /etc/motion/motion.conf

This will now launch the motion client as root when you boot up.

Also note that unless your BeagleBoard can remember the time (battery backed up clock installed) the timestamps will not be correct until you update the time. If your BeagleBoard has an Internet Connection this can be achieved with the ntpdate app.
