Jump to: navigation, search

This page is about running a (ARM EABI) Debian distribution at BeagleBoard. BeagleBoard will boot the (ARM EABI) Debian distribution from SD card. To prepare the SD card and install (ARM EABI) Debian on it, QEMU on host PC will be used, following Aurélien Jarno's excellent Debian on an emulated ARM machine howto.

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

Native Net Install

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

(Testing Release Summer 2010?)

Note: Squeeze hasn't been released, so if you get an error, retry in a couple errors..

https://code.launchpad.net/~beagleboard-kernel/+junk/debian-di

bzr branch lp:~beagleboard-kernel/+junk/debian-di
cd debian-dl
./mk_mmc.sh --mmc /dev/sdX --distro squeeze
  • Options:
    • --distro : lucid, sid, squeeze
    • --firmware : installs firmware
    • --dvi-mode : default, debian-installer uses DVI monitor
    • --serial-mode : debian-installer uses Serial Port

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.
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>

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>

Development PC: Setup U-boot for Normal Boot

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 kernel-image

Script File

Every Kernel upload going further on rcn-ee.net will now have an 'install-me.sh' file in the same directory..

example: http://www.rcn-ee.net/deb/kernel/beagle/lenny/v2.6.32.6-x6.2/

wget http://rcn-ee.net/deb/kernel/beagle/lenny/v2.6.32.6-x6.2/install-me.sh
sudo /bin/bash install-me.sh

Reboot with your new uImage

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

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 uImage and modules 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

Tweak System Libraries:

sudo ln -sf /usr/lib/libXdmcp.so.6.0.0 /usr/lib/libXdmcp.so.0
sudo ln -sf /usr/lib/libXau.so.6.0.0 /usr/lib/libXau.so.0

Startup Script

For 3.01.00.02

Lenny:

sudo nano /etc/rcS.d/S60pvr.sh
sudo chmod +x /etc/rcS.d/S60pvr.sh

Squeeze: (probally lenny too)

sudo nano /etc/init.d/pvr
sudo chmod +x /etc/init.d/pvr
sudo update-rc.d pvr defaults

/usr/bin/pvrsrvinit

Test SGX with a DEMO

In GFX_Linux_SDK:

cd OGLES/SDKPackage/Binaries/CommonX11/Demos/ChameleonMan
./OGLESChameleonMan

Trouble Shooting

sudo rm /etc/powervr-esrev
sudo depmod -a omaplfb
sudo /etc/init.d/pvr restart

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..

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 apt-get install xserver-xorg-video-omap3

EndSection

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

To verify it was correctly installed, reboot and:
