This page is about running a (ARM [http://wiki.debian.org/ArmEabiPort EABI]) [http://www.ubuntu.com/ Ubuntu] distribution at [[BeagleBoard]]. BeagleBoard will boot the (ARM EABI) Ubuntu distribution from [[BeagleBoard#MMC.2FSD_boot|SD card]]. Since much of this page is generic, it has also be extended to help support devices such as the [[PandaBoard]] and [[BeagleBone]].

* These Demonstration Images contain a custom Mainline based kernel with experimental enhancements to the boards supported. They are usually updated about once a month, as new features/enhancements get added by the community. Currently, this image ships with two kernel's "x" which is for mainline omap3+ devices (BeagleBoard/PandaBoard) and the "psp" which is for specifically the BeagleBone, as much of the kernel support for this device is currently in a TI git kernel tree on [http://arago-project.org arago-project]. The kernel is stress tested by a farm of Panda/Beagle's running 24/7 under a heavy load (building gcc trunk/mainline kernel).

If you don't know the location of your SD card:
+
Then follow directions show above with the other images...
sudo ./setup_sdcard.sh --probe-mmc
+
 
+
You should see something like
+
 
+
Are you sure? I Don't see [/dev/idontknow], here is what I do see...
+
+
fdisk -l:
+
Disk /dev/sda: 500.1 GB, 500107862016 bytes '''<- x86 Root Drive'''
+
Disk /dev/mmcblk0: 3957 MB, 3957325824 bytes '''<- MMC/SD card'''
+
+
mount:
+
/dev/sda1 on / type ext4 (rw,errors=remount-ro,commit=0) '''<- x86 Root Partition'''
+
 
+
* In this example, we can see via mount, '''/dev/sda1''' is the x86 rootfs, therefore '''/dev/mmcblk0''' is the other drive in the system, which is the MMC/SD card that was inserted and should be used by ./setup_sdcard.sh...

Quick Install script for "board"
+
sudo ./setup_sdcard.sh --mmc /dev/sdX --uboot "board"
+
 
+
"board" Options:
+
*BeagleBoard Ax/Bx - beagle_bx
+
*BeagleBoard Cx    - beagle_cx
+
*BeagleBoard xMA/B/C    - beagle_xm
+
*BeagleBone Ax    - bone
+
*PandaBoard Ax - panda
+
*PandaBoard ES - panda_es
+
 
+
So For the BeagleBoard xM:
+
sudo ./setup_sdcard.sh --mmc /dev/sdX --uboot beagle_xm
+
 
+
*Additional Options
+
** --rootfs <ext4 default>
+
** --swap_file <swap file size in MB's>

** --addon ulcd <CircuitCo 7 inch lcd>
+
** --svideo-ntsc <use ntsc over dvi for video)
+
** --svideo-pal <use pal over dvi for video)
+
 
+
You should now be able to unmount the SD card from you PC, insert into your Board, reboot and have the OS loaded.
+
 
+
For a basic '''framebuffer''' driven desktop environment: (make sure network is setup):
+
Ethernet: "sudo ifconfig -a" and "sudo dhclient usb1" or "sudo dhclient eth0"

=== U-Boot uImage and uInitrd ===
+
 
+
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
+
Copy "uImage" to the Boot Partition
+
 
+
Next create a uInird (this contains a script to fix the rtc on boot, otherwise fsck/reboot/fsck/reboot/repeat happens..)
+
 
+
mkimage -A arm -O linux -T ramdisk -C none -a 0 -e 0 -n initramfs -d ./initrd.img-* ./uInitrd
+
Copy "uInitrd" to the Boot Partition
+
  
 
=== U-Boot Boot Scripts ===
 
=== 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'.

S-video is tested to be working on 2.6.35-rc5-dl9. BeagleBoard s-video output has traditionally been enabled by "using bootargs (boot arguments) at uboot". In newer versions of the BeagleBoard, the developers have made things easier by instructing u-boot to look for a .scr file about a dozen lines long that is called cmd.boot.scr, and then follow said parameters. In Angstrom, no boot.scr file is needed, instead, an even easier system is used, where a simple editable .txt file called uEnv.txt containing these parameters suffices (Env is for "environment"). For some reason, in the Ubuntu download files, typically there a bit of convoluted process where uEnv.txt is called up, uEnv.txt says "Go read conf.boot.scr", and cmd.boot.scr sets up the s-video.

Depending on your TV device, and what desktop you are running a certain amount of screen cutoff is likely to occur. This is called [http://en.wikipedia.org/wiki/Overscan Overscan]. Typically, around 5-10% of the left and right edges of display are off the screen (using Ubuntu with xfce). This seems to be due to the fact that there is only one display resolution that is set for NTSC: <!-- I don't know about PAL--> 720 X 482. It is not possible to change this setting in the xfce4 Settings Manager like one would normally be able to do, because other options are greyed out/do not exist. Normally, even if the Settings Manager did not allow for it, a different resolution setting could be obtained by editing the xorg.conf file in /etc/X11/xorg.conf-4, or some similar place. HOWEVER there is no xorg.conf file in the Beagle version of xfce. xrandr shows the display is set to the minimum of 720x574. Adding an xorg.conf does not fix the problem, because Beagle takes its (analog) display resolution settings directly from the display driver, where 720 X 480 (720 X 574 for PAL <!-- This I gather, but I really don't know--> ) is hard coded in.

An inelegant but usable workaround for the xfce desktop environment is simply to create vertical and horizontal panels that fill up the space that is cut off on the screen. This is not a complete solution, but at least it will prevent maximized windows from going off into nowhere land.

Truly fixing this would involve going into the display driver and reprogramming it to include additional S-video settings besides just NTSC and PAL. Specifically, to make the whole framebuffer fit on the screen you would need to adjust the overlay in the display driver, the OMAP DSS2. (Didn't test this yet. Some pointers from the driver's documentation below)

(For BeagleBoardAngstrom, click here.)

This page is about running a distribution (ARM EABI) Ubuntu at BeagleBoard. BeagleBoard will boot the (ARM EABI) Ubuntu distribution from the SD card. Since much of this page is generic, it has also be extended to help support devices such as the PandaBoard and BeagleBone.

  • For the best experience, make sure you have an LCD/HDMI monitor attached to the BeagleBoard's HDMI port, 2 GB/4 GB/8 GB SD card, and a known good USB 2.0 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

Mainline U-Boot:

  • All old Ax, Bx, Cx and Dx boards are required to upgrade to at least these U-Boot versions.
  • XM Boards have no NAND, so MLO/u-boot.img is always required on the first partition
  • Directions: Upgrade X-loader and U-Boot

Omap Serial Changes

boot.scr/boot.cmd changes:

With 2.6.35:

console=ttyS2,115200n8

With 2.6.36/37+:

console=ttyO2,115200n8

Serial console login: /etc/init/ttyO2.conf

start on stopped rc RUNLEVEL=[2345]
stop on runlevel [!2345]

respawn
exec /sbin/getty 115200 ttyO2

Method 1: Download a Complete Pre-Configured Image

Canonical/Ubuntu Images

Support: #ubuntu-arm: Ubuntu's ARM IRC on Freenode (logs -> year -> month -> day -> #ubuntu-arm.html)

Canonical only supports certain boards with images, at this moment.

  • BeagleBoard xM -> "omap"
  • PandaBoard & PandaBoard ES -> "omap4"

https://wiki.ubuntu.com/ARM/OMAP

Demo Image

  • These demonstration images contain a custom Mainline based kernel with experimental enhancements to the boards supported. They are usually updated about once a month, as new features/enhancements get added by the community. Currently, this image ships with two kernel's "x" which is for mainline omap3+ devices (BeagleBoard/PandaBoard) and the "psp" which is for specifically the BeagleBone, as much of the kernel support for this device is currently in a TI Git kernel tree on arago-project. The kernel is stress tested by a farm of Panda/Beagle's running 24/7 under a heavy load (building gcc trunk/mainline kernel).
git clone git://github.com/RobertCNelson/stable-kernel.git

If you don't know the location of your SD card:

sudo ./setup_sdcard.sh --probe-mmc

You should see something like

Are you sure? I don't see [/dev/idontknow], here is what I do see...

fdisk -l:
Disk /dev/sda: 500.1 GB, 500107862016 bytes <- x86 Root Drive
Disk /dev/mmcblk0: 3957 MB, 3957325824 bytes <- MMC/SD card

mount:
/dev/sda1 on / type ext4 (rw,errors=remount-ro,commit=0) <- x86 Root Partition
  • In this example, we can see via mount, /dev/sda1 is the x86 rootfs, therefore /dev/mmcblk0 is the other drive in the system, which is the MMC/SD card that was inserted and should be used by ./setup_sdcard.sh...

Install image:

Quick install script for "board"

sudo ./setup_sdcard.sh --mmc /dev/sdX --uboot board

"board" options:

  • BeagleBoard Ax/Bx - beagle_bx
  • BeagleBoard Cx/Dx - beagle_cx
  • BeagleBoard xM - beagle_xm
  • BeagleBone Ax - bone
  • PandaBoard Ax - panda
  • PandaBoard ES - panda_es

So for the BeagleBoard xM:

sudo ./setup_sdcard.sh --mmc /dev/sdX --uboot beagle_xm
  • Additional Options
    • --rootfs <ext4 default>
    • --swap_file <swap file size in MB's>
    • --addon pico <ti pico projector>
    • --svideo-ntsc <use ntsc over dvi for video)
    • --svideo-pal <use pal over dvi for video)

You should now be able to unmount the SD card from you PC, insert into your Board, reboot and have the OS loaded.

For a basic framebuffer driven desktop environment: (make sure network is setup):

Ethernet: "sudo ifconfig -a" and "sudo dhclient usb1" or "sudo dhclient eth0"
Wireless: http://elinux.org/BeagleBoardUbuntu#Wifi_Networking_.28command_line.29

Then run:

/bin/bash /boot/uboot/tools/ubuntu/minimal_lxde_desktop.sh

Additional Expansion Options:

Add "camera=li5m03" to uEnv.txt and run:

/boot/uboot/tools/pkgs/aptina-media-ctl-n-yavta.sh
/boot/uboot/tools/pkgs/aptina-test-capture.sh

Then follow directions show above with the other images...

Method 2: Use the NetInstall method

You will need a 1GB/2GB SD card or greater.

Standard system : ~700 MB

Report Bugs/Issues to: https://github.com/RobertCNelson/netinstall/issues (anywhere else will be ignored..)

Download netinstall script:

git clone git://github.com/RobertCNelson/netinstall.git
cd netinstall

Current Support Ubuntu distributions:

--distro oneiric (11.10)
--distro precise-armhf (12.04)
--distro quantal-armhf (12.10)

Old <board> selection:

*BeagleBoard Ax/Bx - beagle_bx
*BeagleBoard Cx    - beagle_cx
*BeagleBoard xMA/B/C    - beagle_xm
*BeagleBone Ax     - bone
*PandaBoard Ax     - panda
*PandaBoard ES     - panda_es

Install script for <board>

sudo ./mk_mmc.sh --mmc /dev/sdX --uboot <board> --distro <distro>

New <board> selection:

*BeagleBoard xMx - omap3-beagle-xm

Install script for new <board> selection: (slowly migrating all devices to this method)

sudo ./mk_mmc.sh --mmc /dev/sdX --dtb <board> --distro <distro>

So for the xM: with quantal-armhf:

sudo ./mk_mmc.sh --mmc /dev/sdX --uboot beagle_xm --distro quantal-armhf
(or)
sudo ./mk_mmc.sh --mmc /dev/sdX --dtb omap3-beagle-xm --distro quantal-armhf
  • Other Options:
    • --firmware : installs firmware
    • --serial-mode : debian-installer uses Serial Port

Place SD card into BeagleBoard and boot:

Configure the network:

usb0: USB net <- (usually the OTG port)
eth0: USB net <- (usually the smsc95xx adapter on the BeagleBoard and PandaBoard)
wlan0: Wifi <- Your USDB-Wi-Fi device.. 

See my notes for my testing procedure: https://github.com/RobertCNelson/netinstall/blob/master/test.Ubuntu

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:

Assume asll <default>'s... Thanks you preseed.conf!!!

Method 3: Manual Install (no automatic scripts)

For this section, you can use the files from above:

Demo Images: http://elinux.org/BeagleBoardUbuntu#Demo_Image
Rootstock: http://elinux.org/BeagleBoardUbuntu#Build_an_Ubuntu_root_file_system_with_RootStock

BUT it assumes you have your own kernel uImage/modules from any of the many sources..

Partition SD Card

You will need a 1 GB SD card or greater.

Standard Console System : ~286 MB
+ Desktop environment (lxde,gdm) : ~479 MB

Starting with an empty SD card and using gparted, create:

50 MiB Primary Partition, FAT16/FAT32
Rest as ext2/ext3/ext4/btrfs

First, blank the MMC card's partition table with parted: (/dev/sdX as an example)

sudo parted -s /dev/sdX mklabel msdos

With fdisk: (note: GNU Fdisk doesn't work..)

sudo fdisk /dev/sdX << __EOF__
n
p
1

+64M
t
e
p
w
__EOF__

Make sure to set the partition boot flag

sudo parted --script /dev/sdX set 1 boot on

And format it as vfat:

sudo mkfs.vfat -F 16 /dev/sdX1 -n boot

The rootfs partition, doesn't need any special options, so just use fdisk, gparted, etc. to create and format your rootfs partition..

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

Boot Partition

Requirements:

Mount the fatfs partition of your SD card.

Mount such as: (/dev/sdX1 is the fat Boot Partition)

mkdir -p ./tmp
sudo mount /dev/sdX1 ./tmp

MLO and U-Boot

Beagle/Beagle xM

Download and copy MLO and U-Boot from here:

First download "http://rcn-ee.net/deb/tools/beagleboard/MLO-beagleboard-v2012.10-r0" as MLO to the Boot Partition
Then download "http://rcn-ee.net/deb/tools/beagleboard/u-boot-beagleboard-v2012.10-r0.img" as u-boot.img to the Boot Partition

BeagleBone

Download and copy MLO and U-Boot from here:

First download "http://rcn-ee.net/deb/tools/beaglebone/MLO-beaglebone-v2012.10-r1" as MLO to the Boot Partition
Then download "http://rcn-ee.net/deb/tools/beaglebone/u-boot-beaglebone-v2012.10-r1.img" as u-boot.img to the Boot Partition

Panda/Panda ES

Download and copy MLO and U-Boot from here:

First download "http://rcn-ee.net/deb/tools/pandaboard/MLO-pandaboard-v2012.10-r1" as MLO to the Boot Partition
Then download "http://rcn-ee.net/deb/tools/pandaboard/u-boot-pandaboard-v2012.10-r1.img" as u-boot.img to the Boot Partition

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)

boot.scr -> uEnv.txt

Newer version's of u-boot now look for a uEnv.txt file vs the older boot.scr, since most boards still use the older boot.scr here's an easy compatibility script:

create a new file: uEnv.txt

bootenv=boot.scr
loaduimage=fatload mmc ${mmcdev} ${loadaddr} ${bootenv}
mmcboot=echo Running boot.scr script from mmc ...; source ${loadaddr}

Umount the boot partition:

sudo umount ./tmp

RootFS Partition

Root File System

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 arm*-rootfs-*.tgz -C ./tmp
sudo umount ./tmp

Install Latest Kernel Image

Script File

Latest Stable is: https://github.com/RobertCNelson/stable-kernel

export DIST=oneiric  (options are lucid/maverick/natty/oneiric/precise/squeeze/wheezy)
export ARCH=armel (options are armel/armhf (armhf only for precise))

Beagle/Panda
export BOARD=omap

BeagleBone
export BOARD=omap-psp

wget http://rcn-ee.net/deb/${DIST}-${ARCH}/LATEST-${BOARD}

/bin/bash install-me.sh

Reboot with your new uImage.

Upgrade X-loader and U-boot

  • Note: the functionality of the "X-Loader" project has been merged as u-boot spl.

Compatible with old Ax, Bx, Cx, and Dx BeagleBoards

Note: Sometimes on these older boards, you just have to clear out the stored U-Boot environment variables in nand to make this script work:

nand erase 260000 20000

Or: To fully erase the NAND..

nand erase.chip

Requires MMC card..

git clone git://github.com/RobertCNelson/flasher.git
cd flasher

For the Beagle Ax/Bx

sudo ./mk_mmc.sh --mmc /dev/sdX --uboot beagle_bx

For the Beagle Cx/Dx

sudo ./mk_mmc.sh --mmc /dev/sdX --uboot beagle_cx
1: Plug Serial Cable in and Start Serial terminal program
2: Place MMC card in Beagle
3: Push and hold the user button
4: Plug-in power
5: Wait for U-Boot countdown to finish, and let off user button
6: Wait for flashing/script to end
7: Power down, remove and reformat MMC card to final OS

If you don't know the location of your SD card:

sudo ./mk_mmc.sh --probe-mmc

You should see something like

Are you sure? I don't see [/dev/idontknow], here is what I do see...

fdisk -l:
Disk /dev/sda: 500.1 GB, 500107862016 bytes <- x86 Root Drive
Disk /dev/mmcblk0: 3957 MB, 3957325824 bytes <- MMC/SD card

mount:
/dev/sda1 on / type ext4 (rw,errors=remount-ro,commit=0) <- x86 Root Partition
  • In this example, we can see via mount, /dev/sda1 is the x86 rootfs, therefore /dev/mmcblk0 is the other drive in the system, which is the MMC/SD card that was inserted and should be used by ./mk_mmc.sh...

SGX Video Acceleration

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. To change the resolution the DVI output, 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

(For configuring S-Video on Angstrom, click here).

Process for setting up S-Video

S-video is tested to be working on 2.6.35-rc5-dl9. BeagleBoard s-video output has traditionally been enabled by "using bootargs (boot arguments) at uboot". In newer versions of the BeagleBoard, the developers have made things easier by instructing U-Boot to look for a .scr file about a dozen lines long that is called cmd.boot.scr, and then follow said parameters. In Angstrom, no boot.scr file is needed, instead, an even easier system is used, where a simple editable .txt file called uEnv.txt containing these parameters suffices (Env is for "environment"). For some reason, in the Ubuntu download files, typically there a bit of convoluted process where uEnv.txt is called up, uEnv.txt says "Go read conf.boot.scr", and cmd.boot.scr sets up the s-video.

To make cmd.boot.scr, create a text file named cmd.boot, then convert it into a .scr file with mkimage by running the following commands on the terminal:

First, you will probably need to get mkimage with apt-get. Run

   sudo apt-get install mkimage

Next, convert your cmd.boot.scr

   mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n 'Execute uImage' -d boot.cmd boot.scr

Bootargs: make this cmd.boot to set s-video

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

Bootargs that has been validated.

    setenv bootargs 'console=tty0 console=ttyO2,115200n8 root=/dev/mmcblk0p2 rootwait ro vram=12M omapfb.mode=tv:ntsc omapdss.def_disp=tv 
    fixrtc buddy=unknown'

Screen cutoff problem

NTSC resolution is supposed to be 640x480. However the edge bands around the TV screen differ from TV to TV. Output of fbset shown below:

   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

Depending on your TV device, and what desktop you are running a certain amount of screen cutoff is likely to occur. This is called overscan. Typically, around 5-10% of the left and right edges of display are off the screen (using Ubuntu with xfce). This seems to be due to the fact that there is only one display resolution that is set for NTSC: 720 X 482. It is not possible to change this setting in the xfce4 Settings Manager like one would normally be able to do, because other options are greyed out/do not exist. Normally, even if the Settings Manager did not allow for it, a different resolution setting could be obtained by editing the xorg.conf file in /etc/X11/xorg.conf-4, or some similar place. HOWEVER there is no xorg.conf file in the Beagle version of xfce. xrandr shows the display is set to the minimum of 720x574. Adding an xorg.conf does not fix the problem, because Beagle takes its (analog) display resolution settings directly from the display driver, where 720 X 480 (720 X 574 for PAL ) is hard coded in.

An inelegant but usable workaround for the xfce desktop environment is simply to create vertical and horizontal panels that fill up the space that is cut off on the screen. This is not a complete solution, but at least it will prevent maximized windows from going off into nowhere land.

Truly fixing this would involve going into the display driver and reprogramming it to include additional S-video settings besides just NTSC and PAL. Specifically, to make the whole framebuffer fit on the screen you would need to adjust the overlay in the display driver, the OMAP DSS2. (Didn't test this yet. Some pointers from the driver's documentation below)

   /sys/devices/platform/omapdss/overlay? directory:
   enabled		0=off, 1=on
   input_size		width,height (ie. the framebuffer size)
   manager		Destination overlay manager name
   name
   output_size		width,height
   position		x,y
   screen_width	width

Swapfile

Using a File for Swap Instead of a Partition

On the Bealgeboard you should expect to need a swap file given the limitation of how much RAM they have (between 256 MB and 512 MB). Some system programs like apt-get will only run properly when some swap space is present (due to 256 MB not being enough RAM).

Some images such as those from Linaro.org do not come with a swap partition or any swap space allocated.

Under Linux swap space can be either a dedicated partition or a single file. Both can be mounted as swap which the OS can access.

Creating a Swapfile

The following commands will create a 1 gigabyte file, lock access to only root, format it as swap and then advertise it to the OS.

sudo mkdir -p /var/cache/swap/   
sudo dd if=/dev/zero of=/var/cache/swap/swapfile bs=1M count=1024
sudo chmod 0600 /var/cache/swap/swapfile 
sudo mkswap /var/cache/swap/swapfile 
sudo swapon /var/cache/swap/swapfile 

To ask the OS to load this swapfile on each start up, edit the /etc/fstab file to include the following additional line:

/var/cache/swap/swapfile    none    swap    sw    0   0

To verify that the swapfile is accessilble as swap to the OS, run "top" of "htop" at a console.

Ubuntu Software

Wi-Fi Networking (command line)

/etc/network/interfaces

It is possible and relatively easy to configure a Wi-Fi card from the command line.

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

This is a particularly useful guide http://ubuntuforums.org/showthread.php?t=202834

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 Wi-Fi card will automatically load these settings on start up and give network access.

Lightweight window managers

If you intend to use Ubuntu on the BeagleBoard you can install JWM or IceWM to improve performance.

JWM in particular uses little RAM. On a BeagleBoard with 256 MB, using JWM will leave about 60 MB free to run applications in.

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 a 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 X Windows 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 (that is, video output directory, record only video, record in MPEG-4, 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 application.

Robotics

ROS

Willow Garage hosts the open source Robotic Operating System (ROS). Whilst it is natively supported in Ubuntu, the official packages are only for the x86 platform. ROS can be installed from source and is generally easy to do so (although slow).

Following the instructions from here will build and install ROS on your BeagleBoard:

http://www.ros.org/wiki/cturtle/Installation/Ubuntu/SVN

You will need an Internet connection for your BeagleBoard for these scripts to work.

For more information about ROS, see www.ros.org.
