[ECOS] which gcc toolchain to use ?

[Harsha D]

Hi

I have been trying to port ecos on ARM9 based board.
I tried with gcc v4.0 (cygwin) and gcc v3.4.3


In my case i have observed that

in v4.0 > 
	Removing optimization(O2) flag... redboot works
	Including optimization flag... redboot fails 

in v3.4.2	>
	Removing optimization flag... redboot FAILS
	Including optimization flag... redboot works


also....redboot seems to hang at do_version, printing the RAM range.


I would like to know which is the best/suitable gcc toolchain to be used
with eCos


regards
harsha
