Zaurus with u-boot

To get the Zaurus running with uboot you need first get the u-boot installed.
This is done by useing the D+C mechanism
Create a new formatted ( fat ! not ext2 ) SD card with following Layout [[BR ]]

 fdisk  /dev/sdd

Command (m for help): p

Disk /dev/sdd: 32 MB, 32112640 bytes
4 heads, 32 sectors/track, 490 cylinders
Units = cylinders of 128 * 512 = 65536 bytes
Disk identifier: 0x00000000

   Device Boot      Start         End      Blocks   Id  System
/dev/sdd1               1         490       31344    6  FAT16

Command (m for help): 

Put the attached files on this card ( emergenc.img updater.pro u-boot.bin )
Insert this card, remove power and battery
Hold the D abd C button on the keyboard, and insert battery or plug the cable in ( maybe get someone to help you )
The green light gos on for approx 10 seconds ( with power cable the yellow light also )
Now you have installed the uboot and the kexec bootloader
Now format some SD or CF card with ext2/ext3fs and extract your target rootfs on it.
Insert that card
To enter the kexec bootloader, remove Battery, and power cable.
While powering on hold the OK button for 5 seconds. the kexec image boots and show an nice selection screen
With inserted sd card you can boot your image. thats all
to create the emergenc.img from a zImage-kexecbootXXX.bin image use following command:

mkimage -A arm -O linux -T kernel -C none -a 0xa0008000 -e 0xa0008000 -n "Linux 2.6" -d zImage-kexecboot-2.6.32+2.6.33-rc6-r18-spitz.bin /tmp/img

mkimage tool is build within u-boot
