Recommended Beagle Software
xloader xxxx Upgrade
U-Boot 2009 (revC validation) Upgrade: http://elinux.org/BeagleBoardUbuntu#Upgrade_U-Boot
Ubuntu Rootfs Install
Use Oliver's <ogra> script located here: https://wiki.ubuntu.com/ARM/RootfsFromScratch
PC: Build Root File System
Note: Use latest debootstrap, if the one posted here is no longer available.
Requirements:
sudo apt-get install qemu
wget http://ports.ubuntu.com/pool/main/d/debootstrap/debootstrap_1.0.12_all.deb sudo dpkg -i debootstrap_1.0.12_all.deb wget http://people.ubuntu.com/~ogra/arm/build-arm-rootfs sudo chmod u+x build-arm-rootfs
General
sudo ./build-arm-rootfs --fqdn <hostname> --login <rootuser> --password <rootuserpasswd> --imagesize <qemu image size> --seed <packages>
lxde Destktop
sudo ./build-arm-rootfs --fqdn beagleboard --login ubuntu --password temppwd --imagesize 2G --seed lxde,gdm
Xubuntu Desktop
sudo ./build-arm-rootfs --fqdn beagleboard --login ubuntu --password temppwd --imagesize 2G --seed xubuntu-desktop
Ubuntu Desktop
sudo ./build-arm-rootfs --fqdn beagleboard --login ubuntu --password temppwd --imagesize 3G --seed ubuntu-desktop
PC: Format SD Card
You will need a 1GB SD card or greater.
Standard System : ~xxxMB + Desktop environment (GNOME) : ~x.xGB
Starting with an empty SD card and using gparted, create:
50 MiB Primary Partition, fat32 Rest as ext2/ext3
Gparted Example: http://nishanthmenon.blogspot.com/2008/08/how-to-boot-beagle.html
PC: Setup SD uboot/uImage Partition
Mount your SD card fat32 partition. (/media/disk/)
Note: Depending on how your system mounts the cards, you may have to run as sudo.
cd /media/disk/ wget http://www.rcn-ee.com/deb/kernel/CC-v2.6.28-79d042a-oer17 mv CC-v2.6.28-9a6536c-oer17 uImage ext3 wget http://www.rcn-ee.com/deb/kernel/boot-scr/ubuntu-ext3.scr mv ubuntu-ext3.scr boot.scr ext2 wget http://www.rcn-ee.com/deb/kernel/boot-scr/ubuntu-ext2.scr mv ubuntu-ext2.scr boot.scr
Need a different resolution or other setting in the *.scr's? See : http://elinux.org/BeagleBoardUbuntu#U-Boot_Script_Files
Note: CC-v2.6.28-9a6536c-oer8 uImage was built with most/all available usb wifi/ethernet adapter built in to get the beagleboard to connect to the internet. For most people this is all you'll need, however it is recommended to install one of the kernel image deb packages. (script is provided.)
PC: Setup SD ext2/ext3 Partition
Mount your SD ext2/ext3 partition. (/media/disk/)
sudo tar xfp armel-rootfs-[date].tgz -C /media/disk
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
Login thru Serial Port
Create file /etc/event.d/ttyS2
# ttyS2 - getty # # This service maintains a getty on tty6 from the point the system is # started until it is shut down again. start on runlevel 2 start on runlevel 3 stop on runlevel 0 stop on runlevel 1 stop on runlevel 4 stop on runlevel 5 stop on runlevel 6 respawn exec /sbin/getty -L 115200 ttyS2
Note: ubuntu normaly doesn't have a 'root' user, however if you add one, make sure too add ttyS2 to /etc/securetty (by default ttyS0 & ttyS1 are already there)
Beagleboard: Install Kernel Image
Script File
Note: this will be updated from time to time. (tested off course, may need "sudo apt-get install wget")
wget http://www.rcn-ee.com/deb/kernel/ubuntu-update-kernel.sh sudo /bin/bash ubuntu-update-kernel.sh
Note: vmlinuz symbolic link (yes <or> no)... Still not sure this matters, i select <yes>...
Manual Method
You can open/edit the ubuntu-update-kernel.sh to see latest version.
sudo apt-get install uboot-mkimage wget http://www.rcn-ee.com/deb/kernel/beagle/jaunty/v2.6.28-79d042a-oer17/linux-image-2.6.28-oer17_1.0jaunty_armel.deb (or any listed here: http://www.rcn-ee.com/deb/kernel/beagle/jaunty/ ) sudo dpkg -i linux-image*
Extract linux-image's vmlinuz-* (we need this to create the uImage, uboot uses to boot)
dpkg -x linux-image* ./temp
Mount fat32 partition
sudo mount /dev/mmcblk0p1 /mnt
Build uboot compatible image and copy to fat32 boot partition
sudo mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008000 -n "Linux" -d ./temp/boot/vmlinuz-* /mnt/uImage
unmount fat32 partition
sudo umount /mnt
Clean up
rm -rfd temp
Reboot with your new uImage
Advanced
Upgrade U-Boot
Using gparted, create a new 50MB Primary fat32 Partition on a blank SD card, or use your existing fat32 partition.
cd /media/disk sudo wget http://beagleboard.googlecode.com/files/u-boot-f_revc_v3.bin
Tested with (U-Boot 2009.01-dirty (Feb 19 2009 - 12:22:31)) Archive: http://rcn-ee.homeip.net:81/dl/omap/uboot/u-boot-f_revc_v3.bin
Insert SD Card, boot Beagleboard and stop U-Boot from booting
mmcinit fatload mmc 0 0x80200000 u-boot-f_revc_v3.bin nand unlock nand ecc sw nandecc sw nand erase 80000 160000 nand write.i 0x80200000 80000 160000 reset
Note: nandecc sw is a new command to replace nand ecc sw so versions of uboot before 2008.10 will throw an error, it's safe to ignore.
U-Boot Script Files
uboot-mkimage package is required
contents of ubuntu-ext3.cmd
setenv bootcmd 'mmcinit; fatload mmc 0:1 0x80300000 uImage; bootm 0x80300000' setenv bootargs 'console=ttyS2,115200n8 console=tty0 root=/dev/mmcblk0p2 rootdelay=2 rootfstype=ext3 ro omap-dss.def_disp=lcd omapfb.video_mode=1280x720MR-24@60' boot
Create *.scr file
mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n "Boot Time Label" -d ubuntu-ext3.cmd ubuntu-ext3.scr
