      • Copy from serial port or use "dmesg | pastebinit" (sudo apt-get install pastebinit)

Recommended Beagle Software

Ubuntu Rootfs Install

This section describes how you create a Ubuntu root file system for your BeagleBoard.

Note:

  • Jaunty, aka Ubuntu 9.04, is the 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 Feb 2010). Therefore it is listed here as 'testing'. (armv7 optimized)

Development PC: Root File System

Build Image

rootstock is Ubuntu's new name for Oliver's <ogra> depreciated build-arm-rootfs script.

Note: Lucid & Proxy Support is currently in bzr trunk and will release with lucid...

rootstock installation

Note: Use latest debootstrap, if the one posted here is no longer available.

Jaunty (9.04) and Debian:

sudo apt-get install qemu
wget http://ports.ubuntu.com/pool/main/d/debootstrap/debootstrap_1.0.20~jaunty1_all.deb
sudo dpkg -i debootstrap_1.0.20~jaunty1_all.deb
wget http://launchpad.net/project-rootstock/trunk/0.1/+download/rootstock-0.1.3.tar.gz
tar xf rootstock-0.1.3.tar.gz
cd rootstock-0.1.3

Karmic (9.10):

sudo apt-get install rootstock

rootstock trunk:

sudo apt-get install dctrl-tools 
bzr branch lp:project-rootstock

Development PC: Format SD Card

You will need a 1GB SD card or greater.

Standard Console System : ~286MB
+ Desktop environment (lxde,gdm) : ~479MB

Starting with an empty SD card and using gparted, create:

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

Gparted Example: http://nishanthmenon.blogspot.com/2008/08/how-to-boot-beagle.html

For Reference:

Disk /dev/sdd: 2038 MB, 2038431744 bytes
255 heads, 63 sectors/track, 247 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x0008e471

   Device Boot      Start         End      Blocks   Id  System
/dev/sdd1               1           6       48163+   6  FAT16
/dev/sdd2               7         247     1935832+  83  Linux

Development PC: Setup SD Partition's

Requirements:

sudo apt-get install uboot-mkimage

Create uImage for U-Boot

U-Boot needs a compatible kernel image to boot. To do this, we are using mkimage from (uboot-mkimage) to create an image from the vmlinuz kernel file.

mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008000 -n "Linux" -d ./vmlinuz-* ./uImage

Create U-Boot boot image

The version of U-Boot installed or recommended to install uses boot scripts by default. This allows users to easily switch between multiple SD cards with different OS's with different parameters installed. Ubuntu/Debian requires a slight modification to the bootargs line vs. Angstrom, 'ro' vs 'rw'.

Add/Edit ubuntu.cmd

setenv bootcmd 'mmc init; fatload mmc 0:1 0x80300000 uImage; bootm 0x80300000'
setenv bootargs 'console=ttyS2,115200n8 console=tty0 root=/dev/mmcblk0p2 rootwait rootfstype=ext3 ro vram=12M omapfb.mode=dvi:1280x720MR-16@60'
boot

Note: If you created an ext2 root filesystem then change "ext3" above to "ext2"

Use mkimage create to actual *.scr file for U-Boot:

mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n "Ubuntu 9.10" -d ./ubuntu.cmd ./ubuntu.scr

Copy uImage and boot.scr

Mount your SD card fat32 partition (assuming /dev/sdX1) and copy the uImage and boot.scr to the first partition.

Note: if your system automounts the mmc card, just issue "sudo umount /dev/sdX1 && sudo umount /dev/sdX2"

mkdir -p ./tmp
sudo mount /dev/sdX1 ./tmp
sudo cp ./uImage ./tmp/uImage
sudo cp ./ubuntu.scr ./tmp/boot.scr
sudo umount ./tmp

Copy the Ubuntu rootfs

Mount your SD card's ext3 partition (assuming /dev/sdX2) and 'untar' the rootfs into it.

mkdir -p ./tmp
sudo mount /dev/sdX2 ./tmp
sudo tar xfp armel-rootfs-*.tgz -C ./tmp
sudo umount ./tmp

Karmic: (9.10) boot fixup

util-linux-ng 2.16 causes this

Edit /etc/fstab

mkdir -p ./tmp
sudo mount /dev/sdX2 ./tmp
sudo gedit ./tmp/etc/fstab
add:
/dev/mmcblk0p2   /   ext3   errors=remount-ro   0   1

Note change the above "ext3" to "ext2" if the root filesystem is ext2

Add/Edit /etc/e2fsck.conf

sudo gedit ./tmp/etc/e2fsck.conf
[problems]

# Superblock last mount time is in the future (PR_0_FUTURE_SB_LAST_MOUNT).
0x000031 = {
    preen_ok = true
    preen_nomessage = true
} 

# Superblock last write time is in the future (PR_0_FUTURE_SB_LAST_WRITE).
0x000032 = {
    preen_ok = true
    preen_nomessage = true
}

Add karmic updates to /etc/apt/sources.list

sudo gedit ./tmp/etc/apt/sources.list
deb http://ports.ubuntu.com/ubuntu-ports karmic-updates main universe

Finally

cd ./tmp
sync 
cd ..
sudo umount ./tmp

You can now place the SD card into the BeagleBoard and start up the BeagleBoard.

Please be patient as the first boot can take a couple of minutes.

You should be presented with a x-window login screen. If you logged into X windows but do not get a full desktop with window management then execute the command "x-session-manager" at the terminal.

Development PC or Beagleboard: System Setup on the (ext2/ext3) Partition

Enable Network Access

Modify /etc/network/interfaces

auto eth0
iface eth0 inet dhcp

Manual: From the Command line

sudo ifconfig eth0 up
sudo dhclient eth0

or:

sudo ifconfig -a
sudo dhclient ethX

Additional Network Setup Information can be found HERE

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/karmic/v2.6.32.7-x7.1/

wget http://rcn-ee.net/deb/kernel/beagle/karmic/v2.6.32.7-x7.1/install-me.sh
sudo /bin/bash install-me.sh

Note: vmlinuz symbolic link (yes <or> no)...

Reboot with your new uImage

Upgrade U-Boot

Note: C4 ehci compatible

Using gparted, create a new 50MB Primary fat32 Partition on a blank SD card, or use your existing fat32 partition.

cd /media/XXXX-XXXX
sudo wget http://rcn-ee.net/deb/tools/u-boot-beagleboard-2009.11-rc1+r42+gitra5cf522a91ba479d459f8221135bdb3e9ae97479-r42.bin
sudo mv u-boot-beagleboard-2009.11-rc1+r42+gitra5cf522a91ba479d459f8221135bdb3e9ae97479-r42.bin u-boot.bin

Insert SD Card, boot Beagleboard and stop U-Boot from booting

mmc init (or if an really old u-boot) mmcinit
fatload mmc 0:1 0x80300000 u-boot.bin
nand unlock  (old command, removed in later u-boot's)
nandecc sw
nand erase 80000 160000
nand write 0x80300000 80000 160000
nand erase 260000 20000   (Clear old U-boot environment, this enables 'boot.scr' scripts)
reset

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

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

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

Directions:

bzr branch lp:~beagleboard-kernel/+junk/2.6-stable
cd 2.6-stable
. build_kernel.sh
. build_sgx_modules.sh

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

Copy /opt/pvr/pvr script:

Jaunty:

sudo cp /opt/pvr/pvr /etc/rcS.d/S60pvr.sh
sudo chmod +x /etc/rcS.d/S60pvr.sh

Karmic:

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

Note, if your updating..

cat /opt/pvr/pvr | sudo tee /etc/init.d/pvr > /dev/null

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

DSP

This is still a major work in progress...

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.

cat /var/log/Xorg.0.log | grep FBDEV

(II) FBDEV: driver for framebuffer: fbdev
(II) FBDEV(0): using default device
