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

Mainline U-Boot:
** u-boot.bin from here: http://www.angstrom-distribution.org/beagleboard-demo-image-available

* All older BeagleBoard (classic) Ax, Bx, Cx and Dx boards are required to upgrade to at least these U-Boot versions
** Or this one I've archived: [http://elinux.org/BeagleBoardUbuntu#Upgrade_U-Boot U-Boot 2009.08+r37 Upgrade]

= Omap Serial Changes =
This section describes how you create a Ubuntu root file system for your BeagleBoard.
 
  
Note:
+
boot.scr/boot.cmd changes:
* Jaunty, aka Ubuntu 9.04, is the recent 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 Nov 2009). Therefore it is listed here as 'testing'. (armv7 optimized)

50 MiB Primary Partition, fat16/fat32
 
Rest as ext2/ext3

+
This image can be written to a 2GB (or larger) microSD card, via 'dd' on Linux or on Windows/Mac/Linux: https://etcher.io  First press and hold the boot select button (next to the microSD card), then apply power. On boot-up the board should indicate it has started the flashing procedure visually via a Cylon Sweep pattern shown on the 4 LED's next to the Ethernet jack. Progress is reported on both the serial debug and HDMI connectors, once completed all 4 LED's should be full ON.  Simply remove power, remove the microSD card and Ubuntu will now boot directly from eMMC.

On the Beagleboard you should expect to require a swap file given the limitation of how little RAM is available (between 256&nbsp;MB and 512&nbsp;MB). Some system programs like apt-get will only run properly when some swap space is present (due to 256&nbsp;MB not being enough RAM).

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

== Xorg omapfb Drivers ==
+
=== Creating a Swapfile ===
  
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.
+
The following commands will create a 1 GB file, limit access only to root, format it as swap and then make it available to the OS:
  
cat /var/log/Xorg.0.log | grep FBDEV
+
sudo mkdir -p /var/cache/swap/ 
  (II) FBDEV: driver for framebuffer: fbdev
+
  sudo dd if=/dev/zero of=/var/cache/swap/swapfile bs=1M count=1024
  (II) FBDEV(0): using default device
+
  sudo chmod 0600 /var/cache/swap/swapfile
  (II) FBDEV(0): Creating default Display subsection in Screen section
+
  sudo mkswap /var/cache/swap/swapfile
  (==) FBDEV(0): Depth 16, (==) framebuffer bpp 16
+
  sudo swapon /var/cache/swap/swapfile
(==) FBDEV(0): RGB weight 565
 
  
Login into Ubuntu and open a new terminal, xorg has to be running..
+
To tell the OS to load this swapfile on each start up, edit the /etc/fstab file to include the following additional line:
  
xvinfo -display :0.0
+
  /var/cache/swap/swapfile    none    swap    sw    0
X-Video Extension version 2.2
 
  screen #0
 
   no adaptors present
 
  
=== Drivers ===
+
To verify that the swapfile is accessilble as swap to the OS, run "top" or "htop" at a console.

If you intend to use Ubuntu on the BeagleBoard you can install JWM or IceWM to improve performance.
Sorry I don't have an S-Video TV, and this is documented in the source, so it would be really great if someone could fill this section in... --[[User:RobertCNelson|RobertCNelson]] 21:32, 13 July 2009 (UTC)

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

* motion.conf - edit /etc/motion/motion.conf to use 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 contains the following lines:

(For BeagleBoardAngstrom, click here.) (Should Beagleboard:Ubuntu On BeagleBone Black be merged into this page?)

This page is about running a Linux distribution (ARM EABI) Ubuntu on the BeagleBoard. BeagleBoard will boot the (ARM EABI) Ubuntu distribution from the SD card. Since much of this page is generic, it has also been 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 requesting 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 older 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

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

├─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 --dtb board

board options:

  • BeagleBoard Ax/Bx/Cx/Dx - omap3-beagle
  • BeagleBoard xM - omap3-beagle-xm
  • All BeagleBone Variants - beaglebone
  • OMAP5432 uEVM - omap5-uevm
  • BeagleBoard-X15 (BeagleBone AI) - am57xx-beagle-x15

So for the BeagleBoard xM:

sudo ./setup_sdcard.sh --mmc /dev/sdX --dtb omap3-beagle-xm

Flasher

eMMC: All BeagleBone Variants with eMMC

This image can be written to a 2GB (or larger) microSD card, via 'dd' on Linux or on Windows/Mac/Linux: https://etcher.io First press and hold the boot select button (next to the microSD card), then apply power. On boot-up the board should indicate it has started the flashing procedure visually via a Cylon Sweep pattern shown on the 4 LED's next to the Ethernet jack. Progress is reported on both the serial debug and HDMI connectors, once completed all 4 LED's should be full ON. Simply remove power, remove the microSD card and Ubuntu will now boot directly from eMMC.

Script for reference: (this is the script that writes to the eMMC)

https://github.com/RobertCNelson/boot-scripts/blob/master/tools/eMMC/init-eMMC-flasher-v3.sh

This 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. Retry with a 5Volt DC power supply connected.
  • If the 4 LED's blink a constant pattern, the eMMC write has failed. First REMOVE ALL capes, then retry again.

Swapfile

Using a File for Swap Instead of a Partition

On the Beagleboard you should expect to require a swap file given the limitation of how little RAM is available (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 swap file. Both can be mounted as swap which the OS can access.

Creating a Swapfile

The following commands will create a 1 GB file, limit access only to root, format it as swap and then make it available 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 tell 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" or "htop" at a console.

Ubuntu Software

Wi-Fi Networking (command line)

/etc/network/interfaces

It is 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 https://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 upon startup and initialize wireless 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 in which to run applications.

Web Apps

Midori

Given that the BeagleBoard has fewer resources than a desktop a lightweight browser is more responsive. Midori is a lightweight 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 - edit /etc/motion/motion.conf to use 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 contains the following lines:
#! /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 using the ntpdate application.

Robotics

ROS

ROS (Robot Operating System) provides libraries and tools to help software developers create robot applications. It provides hardware abstraction, device drivers, libraries, visualizers, message-passing, package management, and more. ROS is licensed under an open source, BSD license.

There are currently builds of ROS for Ubuntu Bionic armhf. These builds include most but not all packages, and save a considerable amount of time compared to doing a full source-based installation:

Alternatively ROS can be installed from source and is generally easy to do so (although slow).
