Hi, >Thanks to all for the tips. I guess I forgot to look in the most obvious >place first. I'll give "m68k-stub.c" a go. Paul Breed [Paul at Netburner.com] has built a stub for the ColdFire but I'm not sure if it will work with the m68k. You can find it at: http://www.netburner.com/updates/gdbstub.zip I haven't had time to look at it yet. Dave
