Look at how RedBoot is configured for that platform.  It is a stand 
alone program, built from the eCos sources.

I'd guess that the problem lies with your turning off of the virtual
vector stuff.  This doesn't cost you anything and for a stand alone
program, your program will provide the actual I/O (again, look at
RedBoot since it uses virtual vector support).
