0xfffff000 is the start of ppc/u-boot. Break out a copy of GDB and start tracing into it to find out where it's blowing up. Build ppc/u-boot with "-fno-schedule-insns -fno-schedule-insns2" added to the compile line. --Chris ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
