Andrew and Oliver,

Thanks a lot for the information. I agree that RedBoot is not appropriate
for such a platform. I always built my own bootloaders on such smaller
embedded platform in the past. But was wondering if eCos must have RedBoot
installed for its HAL is from Redboot.

I am trying to install the CVS client and download eCos now.

You need the latest eCos from anonymous CVS:

http://ecos.sourceware.org/anoncvs.html

Personaly, i don't recommend using Redboot with this system. I do all
my development using eCos ROM applications and JTAG for download and
gdb. This removes the need for RedBoot.

You are correct in that there are no instructions for installing
RedBoot. The webpage is generated automatically using server side
includes and i don't think i can turn that off.
