 I'm trying to debug Linux kernel on the Sandpoint X3 with MPC755 CPU board.
I'm using BDI 2000 with GDB.
I configured gdb v.5.3 as follows

  configure --prefix=/usr/local/cross-ppc/host/intel/ --target=powerpc-linux

 While I used the gdb with BDI, the breakpoints set by gdb do not work well.
It doesn't stop.
After a while, I typed Ctrl-C to stop it. Then it shows the messages shown
And then it terminates. Could it be GDB configuration problem?
Has anybody got similar problem?

 Thanks in advance.


Program received signal SIGSTOP, Stopped (signal).

Cannot remove breakpoints because program is no longer writable.
It might be running in another process.
Further execution is probably impossible.
