you would need to get a toolchain that specifically supports it. a simple binutils/gcc cross-compiler wont work because you need the external "elf2flt" package integrated, and doing so is non-trivial. personally, ive never used ARM/nommu, but i believe you want this toolchain: http://www.codesourcery.com/sgpp/lite/arm/portal/release1588 and then simply compiling a simple app like: main(){puts("hello");} should produce a FLAT file you can run. this is how you do it for a Blackfin FLAT, and i imagine the ARM method is the same: $ echo 'main(){puts("hello");}' > test.c $ bfin-uclinux-gcc test.c $ file a.out a.out: BFLT executable - version 4 ram $ qemu-bfin ./a.out hello -mike
