We do not know if it works or not. The iPAQ the we had connected via JTAG,
does not accept JTAG commands anymore. We are waiting to get an extra unit
to test the saved WinCE image.

returning WinCE is the easy part. You would issue the over ride command in
the bootldr 'set override 1' followed with a 'load flash 0x0' command, then
start a xmodem download of the saved WinCE image.

You are correct, I will fix the typo, asap.

For newer version there are several methods you can go back to the boot
loader use the:

load bootldr
load ramdisk
load kernel

commands. For v0.12, you can also use 'mkfs -ext2 /dev/ram2', 'mount
/dev/ram2 /mnt/hda', 'rz filename', with 'dd if=filename of=/dev/flash?'
where:

/dev/flash1 - kernel
/dev/flash3 - ramdisk
/dev/flash4 - cramfs - main
/dev/flash5 - cramfs - /usr directory

or you can do a similar variation of the above via Ethernet, if you have a
CF sleeve and an Ethernet card.

I hope this helps,

Best Regards,
