I'm trying to compitle a rommable image for the aeb1C. The aeb1c has a bootloader that requires each rommable program to have a module header - which I have placed in a file called module.c. This module header is simply a struct containing static information about the location of the code, name of module, etc. & is not referenced anywhere else in the program. The problem is that this variable disappears when the program is compiled. Maybe it gets eliminated because it's never referenced? I don't think I have any optimizations turned on - will arm-elf-gcc simply do this on it's own? Is there a way to turn it off? Nicole Cook
