Note that ARM does not support big endian code. Code is always little endian - only data accesses can be big endian. You can change data access endianness using the SETEND instruction: http://infocenter...

I believe that big-endian support is an optional compile time build option for the GCC compiler itself, and not many pre-built versions for ARM support it as it is so rarely used, so you may need to re-build your own compiler with big-endian support.
