This page is about running a (ARM EABI) Debian distribution at BeagleBoard. BeagleBoard will boot the (ARM EABI) Debian distribution from SD card. Debian's NetInstall will be used to install Debian onto your Beagle.

Note: Debian armel deb's are compiled for armv4t, this allows debian to support a larger number of arm devices with a single port, at only the sacrifice of speed.

Help

If you need any help:

  • 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)

Recommended 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

Debian NetInstall

You will need a 1GB SD card or greater.

Standard System : ~455MB
+ Desktop environment (GNOME) : ~2.9GB

Debian Squeeze

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

Install script for Beagle Bx

./mk_mmc.sh --mmc /dev/sdX --uboot beagle_bx --distro squeeze

Install script for Beagle Cx, xM A/B/C

./mk_mmc.sh --mmc /dev/sdX --uboot beagle --distro squeeze

Install script for Panda

./mk_mmc.sh --mmc /dev/sdX --uboot panda --distro squeeze
  • Options:
    • --uboot : beagle, (panda only serial, display not working)
    • --distro : squeeze
    • --firmware : installs firmware
    • --serial-mode : debian-installer uses Serial Port
    • --usb-rootfs : (uImage on /dev/mmcblkp0 and rootfs on external usb drive /dev/sda1)

Note: The default 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-squeeze.cmd
gedit ./netinstall-omap/scripts/serial-normal-squeeze.cmd

Beagleboard: NetInstall

Choose a language
 C - No localization
 English - English
Configure the network:
 usb0: USB net <- (usually the OTG port, but could also be the smsc95xx adapter on the beagle and panda)
 usb1: USB net <- (usually the smsc95xx adapter on the beagle and panda, when usb0 exist)
 eth0: Ethernet <- Your usb-ethernet device
 wlan0: Wifi <- Your usb-wifi device.. See BeagleBoardDebianWifiInstallInfo for my hack to set it up.

usb0 howto

There's a lot of question on irc about this, it might make sense to add a wiki page going thru with linux/winxp etc.. --RobertCNelson 00:55, 23 April 2010 (UTC)

Configuring usb0 network bridge for 2.6.29:
 While you chose your keyboard layout, setup a bridge with ethX and usbX.
  # ifconfig ethX 0.0.0.0
  # ifconfig usbX 0.0.0.0
  # brctl addbr brX
  # brctl addif brX ethX
  # brctl addif brX usbX
  # ifconfig brX up
  # dhclient brX
 *Sometimes the first beagle DHCP will fail(probably due PC trying autoconnect), just run the auto configuration again and it will configure it right.
Continue the install without loading kernel modules? : <yes>
Partition disks: This partitioner doesn't have the inform.....? : <yes>
 Logical Volume Manager not available: <Continue>
Partition disks:
 Guided - Use the largest continuous free space
Partitioning scheme....

Example:

MMC/SD card #1 (mmcblk0) - 2.0 GB Unknown
>  #1 primary  57.5 MB     fat32
>  #2 primary   1.8 GB B f ext3  /
>  #5 logical 148.0 MB   f swap  swap
Finish partitioning and write changes to disk
 Write the changes to disk? : <yes>
No installable kernel was found in the defined APT sources? : 
 Continue without installing a kernel? : <yes>
Standard System
No BootLoader: <ok>

Beagleboard: Install Latest Kernel

Script File:

Lenny:
wget http://rcn-ee.net/deb/kernel/beagle/lenny/v2.6.32.11-x13/install-me.sh
sudo /bin/bash install-me.sh

Squeeze:
export DIST=squeeze
wget http://rcn-ee.net/deb/${DIST}/LATEST
wget $(cat ./LATEST | grep STABLE | awk '{print $3}')
/bin/bash install-me.sh

Reboot with your new Kernel

Debian Configuration

Serial Ports

Lenny

edit /etc/inittab and add:

S:2345:respawn:/sbin/getty 115200 ttyS2

For root access over the serial port add ttyS2 to /etc/securetty


Squeeze

edit /etc/inittab and add:

S:2345:respawn:/sbin/getty 115200 ttyO2

WiFi

See BeagleBoard Debian WiFi install info.

SGX Video Acceleration

Requirements: 2.6-stable from launchpad or 2.6.35.3-x1+ deb's from rcn-ee.net. (the Demo Images hosted on rcn-ee.net meet this requirement)

 https://github.com/RobertCNelson/stable-kernel

Note: An older version of these instructions was adapted for the IGEPv2 platform - if you are following this tutorial and have an IGEPv2, consider using http://wiki.jmaustin.org/wiki/IgepSGXUbuntu instead

SDK unPackage Script

Download the latest version of the "create_sgx_package.sh" script

2.6.37
wget https://github.com/RobertCNelson/stable-kernel/raw/master/create_sgx_package_2.6.37.sh
2.6.38+
wget https://github.com/RobertCNelson/stable-kernel/raw/master/create_sgx_package.sh

Make script executable

chmod a+x ./create_sgx_package.sh

Run script

./create_sgx_package.sh

After Successfully running:

:~/temp$ ls
create_sgx_package.sh
GFX_X_XX_XX_XX_libs.tar.gz                      : -> Copy to Beagle (System Libs)
GFX_Linux_SDK.tar.gz                            : -> Copy to Beagle (DEMO's)
Graphics_SDK_setuplinux_X_XX_XX_XX.bin
SDK
SDK_BIN

Beagle: GFX_*_libs.tar.gz

tar xf GFX_4_00_00_01_libs.tar.gz  (extracts install-SGX.sh and run-SGX.sh)
./install-SGX.sh (copies necessary SGX libs and startup script)
./run-SGX.sh (force run the new init script, or you can just reboot...)

On Successful install:

Stopping PVR
Starting PVR
Starting SGX fixup for ES2.x (or ES3.x) (or ES5.x xM)

Reboot for good measure

sudo reboot

Beagle: GFX_Linux_SDK.tar.gz

tar xf GFX_Linux_SDK.tar.gz
cd GFX_Linux_SDK
tar xf OGLES.tar.gz

Test SGX with a DEMO

cd OGLES/SDKPackage/Binaries/CommonX11/Demos/EvilSkull
./OGLESEvilSkull

Xorg omapfb Drivers

By default Debian 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.

Lenny might need this xorg.conf, but it's best to use omapfb later in this guide..

/etc/X11/xorg.conf:

Section "Device"
	Identifier	"Configured Video Device" 
	Option		"UseFBDev"		"true"
	Driver		"fbdev"
EndSection

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 Debian and open a new terminal, xorg has to be running..

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)

Lenny:

wget -c http://rcn-ee.homeip.net:81/dl/deb-sbuild/lenny/xorg-drivers/xserver-xorg-video-omap3_0.1.1-2_armel.deb
sudo dpkg -i xserver-xorg-video-omap3_0.1.1-2_armel.deb

Squeeze/Sid:

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

xorg.conf

/etc/X11/xorg.conf

Section "Monitor"
    Identifier "Configured Monitor"
EndSection

Section "Screen"
    Identifier "Default Screen"
    Device "Configured Video Device"
    #Limited by SGX?
    DefaultDepth 16
EndSection

Section "Device"
    Identifier "Configured Video Device"
    Driver "omapfb"
    Option "fb" "/dev/fb0"
EndSection

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
