Aha, thats good to know :-)

Do you mean internal RAM or potentional attached external RAM?
Well, yes, modifying the ram file for the internal RAM...

My question is, did you apply any eb40a patches or are you talking of
/ecos/packages/hal/arm/at91/current/include/pkgconf/mlt_arm_at91_eb40_ram.[h|ldi]
of the ecos-2.0b tree?

> I try that and it works!!

Two final Questions and I have much to play @work on monday :-):
What gcc version did you use, is it save to use 3.2.2 or is it more save
to use 2.95.3? Today I switched my arm-elf toolchain to gcc-2.95.3
anyhow...
What commands did you pass two arm-elf-gdb to download the redbbot.elf
to the eb40a? Any enabling or changing of registers or so?

Good Luck!

*gnarf* 1st I am desperately trying to fire up redboot_RAM, then I will
help in the flash part :-)
