OK. Actually I probably didn't phrase that very well. What I meant is that 
I got the impression of the 7212 configuration being derived from one of 
the existing configs, and maybe someone hadn't gone through absolutely 
every single thing that needed to be altered. But anyway, it's no matter - 
normally everything works fine for me.

Yes.

What I do is to maintain three directories: "ecos" (current), "ecos_rom" 
and "ecos_ram". I keep a built copy of the library/header/etc in each of 
those directories. The makefile for my main project references "../ecos" 
and so when I want to switch configs I do make clean in my project 
directory, then cp -r ../ecos_rom/* ../ecos (or cp -r ../ecos_ram/* 
../ecos) and rebuild my application.

OK, I will do - thanks. I've got a couple of other quick debuggery things 
to try.

I do have one other issue: when I build for ROM target with the anoncvs 
sources, I get a #error "no RESET_ENTRY". Reading the appropriate 
sourcefile I see what that is all about, but I don't know where would be an 
appropriate _portable_ place to define my own reset entry point. Where 
should I define that?
