The effect is the same but the setting of ENV_IS_EMBEDDED is neither 
here nor there as I'm starting from a configuration file for the FADS 
board. This has only 8 sectors of 256k each so it makes no sense to 
embed the environment (wastes too much space) - the problem as you say 
is that it never gets copied out of Flash into RAM !!

I'm going to 'have a go' at cpu/mpc8xx/start.S to modify it for the FADS 
case but since I've never used ppc assembler before it may take a while!!

I think if I can identify where I get the source (presumably 
GOT(environment)) and destination (not found this yet) addresses and the 
length of the environment (I'll use the config define) at the assembler 
level then I'll be able to hack something together!!

Never will so few lines of code have taken so long to write :-))
