Can I install U-Boot over redboot for booting Windows CE

Simply installing U-Boot over RedBoot will result in a system that comes up with U-Boot running, but (probably) _can't_ boot CE!

Usually MS Windows CE is booted by Eboot which is built with the CE kernel NK.bin (a Microsoft proprietary format) or NK.nb0 (raw binary).

Assuming RedBoot is the bootloader for your MS Windows CE kernel, you simply need to get U-Boot to duplicate the sequence of actions that RedBoot currently does to boot MS Windows CE.

I would guess that your RedBoot bootloader is either directly loading the NK.nb0 raw CE kernel image or it is chainloading Eboot (presumably from the same boot device as RedBoot) and Eboot loads the NK.bin CE kernel image. (Note that the first option is preferable, since two bootloaders on the same system is problematic.)

You need to provide more information, like what board are you using, what the boot devices are, and how RedBoot is currently booting CE, etc.
