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.

= Help =

If you need any help:


 * Kernel related help:
 * Email Beagleboard user group *Recommended method
 * #beagle: Beagle irc on freenode, accessible also by web interface (logs)
 * Launchpad Project "Beagleboard Kernel"
 * Stable Kernel 2.6.35 src
 * Development Kernel src
 * Kernel Testing Results


 * 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

= NetInstall Method =

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

Script Source: https://code.launchpad.net/~beagleboard-kernel/+junk/debian-di

Install bzr sudo apt-get install bzr

Download debian-di script bzr branch lp:~beagleboard-kernel/+junk/debian-di

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 initrd.img-2.6. -> 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

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

Manual: From the Command line sudo ifconfig -a sudo dhclient ethX (or wlanX/etc..)

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 (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

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 X-Video Extension version 2.2 screen #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 (II) LoadModule: "omapfb" (II) Loading /usr/lib/xorg/modules/drivers//omapfb_drv.so (II) Module omapfb: vendor="X.Org Foundation" (II) omapfb: Driver for OMAP framebuffer (omapfb) and external LCD controllers: (WW) Error opening /sys/devices/platform/omapfb/ctrl/name: No such file or directory (II) omapfb(0): VideoRAM: 1800KiB (SDRAM) (II) omapfb(0): Creating default Display subsection in Screen section (**) omapfb(0): Depth 16, (--) framebuffer bpp 16 (==) omapfb(0): RGB weight 565 (==) omapfb(0): Default visual is TrueColor (--) omapfb(0): Virtual size is 1280x720 (pitch 1280) (**) omapfb(0): Built-in mode "current" (==) omapfb(0): DPI set to (96, 96) (II) omapfb(0): DPMS enabled (II) omapfb(0): Video plane capabilities: (II) omapfb(0): Video plane supports the following image formats: (II) omapfb(0): XVideo extension initialized

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
I do not have PAL tv, most likely changing above to omapfb.mode=tv:pal should work. Someone with access to PAL tv please check and update.

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

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:

/usr/bin/motion -c /etc/motion/motion.conf
 * 1) ! /bin/sh

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.
