You need: MMU XLAT 0xc0000000 PTBASE 0x000000f0 The newer kernels initialize the page table pointers for the BDI2000, so ignore comments about stopping and setting values. We went through several iterations of implementation, so anything written about how to do this manually is probably wrong :-). > ......

You need the BDI connected to set and trap the breakpoint. Have fun. -- Dan ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
