[ECOS] problem building application

I have the startup type set to RAM.  But it still seems to be reading in the 
romram configuration.  Also my a.out file is ~1.2M, which seems very high.  I 
am using the default configutation for ecos, and redboot for the redboot 
image.

Changing that number made my errors go away, but that means it must be using 
romram instead of ram.

thanks,
Aaron
