Sorry, I just fount there was a problem not on debugger but compiler. When I loaded x86 object file to gdb for powerpc (It seems symbols are compatible) I can see the functions. but loaded ppc object file to gdb for x86 I can't see the functions.
The compiler for ppc is gcc on HHL developement kit. Of course I gave option '-g'. ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
