Hi , I was trying to debug the kernel with the help of BDI, but couldn't do so as gdb is dying itself. I am using monta vista cross-compiled gdb. Here what i do to debug the kernel. 1. boot the board (I am using ppcboot)[Board is connected with BDI] 2. After that I start the ppc_405-gdb on host. 3. Enter C to continue. 4. Then I press CTRL-C to stop the gdb , then it stops the kernel. 5. Now I try to add the symbol file (vmlinux). When i do the 5th step , my gdb dies , it says : Reading Symbols from vmlinux.... Segmentation fault (core dumped). Thankx Sanjay ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
