Hmm... I remember, you actually need to do something in Crt0. My implementation is a bit naive. I just made it so the linker would be happy, never thought about it working. I believe setting up a stack should help matters a bit. I'll look at dietlibc for ideas. I suck at ppc assembly, so I might need some help on this. -- Remco Treffkorn (RT445) HAM DC2XT remco@rvt.com (831) 685-1201
