BeagleBoardUbuntu

(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:


 * Kernel related help:
 * Email Beagleboard user group *Recommended method
 * #beagle: Beagle IRC on Freenode, accessible also by web interface (logs)
 * Kernel Tree's
 * Stable (3.7.x) branch
 * Development Kernel source code


 * 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 BeagleBoard (classic) 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

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).

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/sdd: 3957 MB, 3957325824 bytes <- MMC/SD card lsblk: NAME  MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT sda     8:0    0 465.8G  0 disk ├─sda1  8:1    0 446.9G  0 part /  <- x86 Root Partition ├─sda2  8:2    0     1K  0 part └─sda5  8:5    0  18.9G  0 part [SWAP] sdd     8:48   1   3.7G  0 disk ├─sdd1  8:49   1    64M  0 part └─sdd2  8:50   1   3.6G  0 part


 * In this example, we can see via mount, /dev/sda1 is the x86 rootfs, therefore /dev/sdd 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/Cx/Dx   - beagle
 * BeagleBoard xM      - beagle_xm
 * BeagleBone/Black    - bone
 * PandaBoard & ES     - panda

So for the BeagleBoard xM: sudo ./setup_sdcard.sh --mmc /dev/sdX --uboot beagle_xm

Quick install script for "board" (using new --dtb option) sudo ./setup_sdcard.sh --mmc /dev/sdX --dtb board

"board" options:
 * BeagleBoard xM      - dt-beagle-xm

So for the BeagleBoard xM: sudo ./setup_sdcard.sh --mmc /dev/sdX --dtb dt-beagle-xm


 * Additional Options
 * --rootfs
 * --swap_file 
 * --addon pico
 * --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.

eMMC: BeagleBone Black
This image can be written to a 1Gb (or greater) microSD card, via 'dd' in linux or the win32 image program linked to on CircuitCo's wiki page. First hold down on the boot select button (next to microSD card) and apply power (same procedure as the official CircuitCo images), it should boot into Ubuntu and begin flashing the eMMC, once completed all 4 LED's should be full ON... Simply remove power, remove microSD card and Ubuntu will now boot from eMMC.

Script for Reference: (this is the script that writes to the eMMC) https://github.com/RobertCNelson/tools/blob/master/scripts/beaglebone-black-copy-microSD-to-eMMC.sh

BTW: we are only writing about 500Mb's to the eMMC so the script will only take about 5-6 Minutes after power on.

Notes:
 * If only two LED's stay lit and nothing happens, the board has crashed due to lack of power. Try with a 5Volt DC supply plugged in..
 * If the 4 LED's blink a constant pattern, eMMC write failed, first REMOVE ALL capes, then retry again.
 * (error -84: which may mean you've reached the max number of erase/write cycles...)

Follow the "standard" update procedure. http://circuitco.com/support/index.php?title=Updating_The_Software

= 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 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 sudo ./mk_mmc.sh --mmc /dev/sdX --uboot --distro

New selection: *BeagleBoard xMx - omap3-beagle-xm

Install script for new selection: (slowly migrating all devices to this method) sudo ./mk_mmc.sh --mmc /dev/sdX --dtb --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

Troubleshooting: If boot fails.. nand erase 260000 20000
 * 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:

NetInstall assumptions: Assume asll 's... Thanks you preseed.conf!!!

= Method 3: Manual Install (no automatic scripts)=

Note, this section use to have a lot of details, but maintenance of the two wiki's became a pain, so for now on we will just link to my other pages:

Script File
WARNING It seemed real obvious at the time I wrote this script, it is ONLY supported for images hosted on "rcn-ee.net/elinux.org"... Images from anywhere else, you are on your own...

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

export DIST=raring (options are lucid/precise/quantal/raring/saucy/squeeze/wheezy/jessie) export ARCH=armhf (options are armel/armhf) Beagle/Panda export BOARD=omap BeagleBone export BOARD=omap-psp wget http://rcn-ee.net/deb/${DIST}-${ARCH}/LATEST-${BOARD} wget $(cat ./LATEST-${BOARD} | grep STABLE | awk '{print $3}') /bin/bash install-me.sh

Reboot with your new Kernel Image.

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
BeagleBone (BBW) & BeagleBone Black (BBB)
 * NOTHING in this section currently applies to your device, as we are waiting for 3.8/kms/drm bits from TI.

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.

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 global_alpha  	global alpha 0-255 0=transparent 255=opaque

= 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 =

/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  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.

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 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:

/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 application.

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.
