 You should del "PARAMETER flash_memory_bank = 0" (it should be the 
default value of "-1" in software setting) in your mss, if you don't 
have any flash.

I think this is because you are using uClinux version 1.00.c, change it 
to 1.00.a should resolve this error. Apparently 1.00.c is not finalize 
yet (it will give out error when flash controller is not enabled), thats 
why John hasn't announce on the website (although you can download them 
from the website).

FYI, here is a documentation of creating a simple hardware platform
