BeagleBoardDebian

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:


 * Kernel related help:
 * Email Beagleboard user group *Recommended method
 * #beagle: Beagle irc on freenode, accessible also by web interface (logs)
 * Launchpad Project "Beagleboard Kernel"
 * Launchpad Stable Kernel 2.6.32 src
 * Launchpad Development Kernel 2.6.32 src
 * Launchpad Mainline Kernel git src *Unless you know what your doing, do NOT use the 2.6-mainline branch...
 * Kernel Testing Results


 * 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 =
 * Recent x-loader/MLO (1.4.4ss)
 * All Bx C2/3/4 Boards should upgrade their MLO from here: Upgrade X-loader and U-boot


 * Recent U-Boot (2010.03-rc1)
 * u-boot.bin from here: http://www.angstrom-distribution.org/beagleboard-demo-image-available
 * Or this one I've archived: Upgrade X-loader and U-boot
 * Version 2009.01 (factory installed on C2/3's) and earlier will not work with this guide
 * Version 2009.11-rc1-00601-g3aa4b51 (factory installed on C4's) should be upgraded
 * 'mmc init' change

Development PC: Format SD Card
Planning to remove this section, pending Squeeze's Release...

You will need a 1GB SD card or greater. Standard System : ~455MB + Desktop environment (GNOME) : ~2.9GB

Starting with an empty SD card and using gparted, create: 50 MiB Primary Partition, fat32 Leave remaining space for the Debian-Installer

Development PC: Setup SD U-boot Partition
Mount your SD card fat32 partition. (/media/disk/)

Debian Lenny
cd /media/disk/ sudo wget http://rcn-ee.net/deb/kernel/CC-beagle-v2.6.29-58cf2f1-oer44.1.uImage sudo wget http://ftp.debian.org/debian/dists/lenny/main/installer-armel/current/images/versatile/netboot/initrd.gz sudo mv CC-beagle-v2.6.29-58cf2f1-oer44.1.uImage uImage sudo gzip -d initrd.gz sudo dd if=initrd of=initrd.pad ibs=8388608 conv=sync

Create U-boot boot script for netinstall:

Debian Install over DVI Port sudo nano netinstall.cmd setenv bootcmd 'mmc init; fatload mmc 0:1 0x80300000 uImage; fatload mmc 0:1 0x81600000 initrd.pad; bootm 0x80300000' setenv bootargs 'console=tty0 ramdisk_size=8192 root=/dev/ram0 rw rootfstype=ext2 initrd=0x81600000,8M omapfb.mode=dvi:1280x720MR-16@60' boot

Debian Install over the Serial Port sudo nano netinstall.cmd setenv bootcmd 'mmc init; fatload mmc 0:1 0x80300000 uImage; fatload mmc 0:1 0x81600000 initrd.pad; bootm 0x80300000' setenv bootargs 'console=ttyS2,115200n8 ramdisk_size=8192 root=/dev/ram0 rw rootfstype=ext2 initrd=0x81600000,8M' boot

Create U-boot *.scr file:

sudo mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n "Debian Lenny" -d ./netinstall.cmd ./boot.scr

Sync and Unmount your mmc card and boot the beagle, it should find the 'boot.scr' file on your first partition while booting.

Debian Squeeze
Squeeze has not been released, (Summer 2010) therefore nothing is promised etc...

https://code.launchpad.net/~beagleboard-kernel/+junk/debian-di bzr branch lp:~beagleboard-kernel/+junk/debian-di cd debian-di ./mk_mmc.sh --mmc /dev/sdX --distro squeeze --firmware


 * Options:
 * --distro : squeeze, lucid
 * --firmware : installs firmware
 * --serial-mode : debian-installer uses Serial Port

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 ./debian-di/scripts/dvi.cmd gedit ./debian-di/scripts/serial.cmd Normal Boot Settings: gedit ./debian-di/scripts/dvi-normal-squeeze.cmd gedit ./debian-di/scripts/serial-normal-squeeze.cmd

Beagleboard: NetInstall
Choose a language C - No localization English - English

Configure the network: usb0: USB net <- See below for 2.6.29. Could not find usb0 with B7 installing 2.6.28. 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.

Development PC: Setup U-boot for Normal Boot
Planning to remove this section, pending Squeeze's Release... I moved the relevant data to: http://elinux.org/BeagleBoardDebian#U-boot_Scripts

Create a U-boot normal boot script:

DVI Port sudo nano normal.cmd setenv bootcmd 'mmc init; fatload mmc 0:1 0x80300000 uImage; bootm 0x80300000' setenv bootargs 'console=tty0 root=/dev/mmcblk0p2 rootwait rootfstype=ext3 ro omapfb.mode=dvi:1280x720MR-16@60' boot

Serial Port sudo nano normal.cmd setenv bootcmd 'mmc init; fatload mmc 0:1 0x80300000 uImage; bootm 0x80300000' setenv bootargs 'console=ttyS2,115200n8 root=/dev/mmcblk0p2 rootwait rootfstype=ext3 ro' boot

Create U-boot *.scr file:

sudo mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n "Debian Lenny" -d ./normal.cmd ./boot.scr

Debian will fix the ext3 partition, it'll try to reboot, after halting remove and reapply power.

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

Reboot with your new Kernel

U-boot Scripts
Create a U-boot normal boot script:

DVI Port sudo nano normal.cmd setenv bootcmd 'mmc init; fatload mmc 0:1 0x80300000 uImage; bootm 0x80300000' setenv bootargs 'console=tty0 root=/dev/mmcblk0p2 rootwait rootfstype=ext3 ro omapfb.mode=dvi:1280x720MR-16@60' boot

Serial Port sudo nano normal.cmd setenv bootcmd 'mmc init; fatload mmc 0:1 0x80300000 uImage; bootm 0x80300000' setenv bootargs 'console=ttyS2,115200n8 root=/dev/mmcblk0p2 rootwait rootfstype=ext3 ro' boot

Create U-boot *.scr file:

sudo mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n "Debian Lenny" -d ./normal.cmd ./boot.scr

Debian will fix the ext3 partition, it'll try to reboot, after halting remove and reapply power.

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

WiFi
See BeagleBoard Debian WiFi install info.

SGX Video Acceleration
Use a "corporate email" and download the latest (3.01.00.02): http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/gfxsdk/latest/index_FDS.html

Kernel Modules
Use the "build_sgx_module.sh" script in 2.6-stable, module source is now in the *.bin

https://code.launchpad.net/~beagleboard-kernel/+junk/2.6-stable

Copy the *.uImage and extract the matching *.modules.tar.gz from the deploy directory to your SD card.

Copy the GFX_Linux_SDK.tar.gz examples to either your SD card or another media (large file) then boot your omap board.

Run depmod: sudo depmod -a omaplfb

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..
