ARM binaries are not portable between different ARM cpus, even between those wh= ich claim to be of the same 'family'. The devil is in the details, as they say.= And it is not just IO addresses and accessing modes, as far as I could see so f= ar. ARM code is portable as long as it is written in C or higher level assembly apparently, and can be built for the specific target cpu. -- Peter --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
