Depending how crappy the existing assembler/linker are it may be easier to do a gas/binutils/ld ELF port. Non-elf ports are generally a pain and I'd advise avoiding them wherever possible. You can always write a postlinker to convert an elf image into whatever format your loader is expecting. This is what uClinux and SymbianOS do. Paul
