Because I can see the following messages from host and target respectively: [target] IP=10.11.27.244 ./gdbserver :6666 ./mytest Process ./mytest created; pid=19 Remote debugging using :6666 [host] which is a x86 box powerpc-linux-gdb --baud 9600 mytest (gdb)target remote 10.11.27.244:6666 Remote debugging using 10.11.27.244:6666 0x30016a7c in ??() (gdb) Has the host and the target been connected via network yet? If so, I type "run" after (gdb) at host side, then (gdb)run The program being debugged has been started already Start it from the begging?(y or n) y Starting program: /mytest/mytest Don't know how to run. Try "help target". I don't know why the program is running at this time. type "list" can show my source code. type "b main" can set breakpoint . (gdb) b main Breakpoint 1 at 0x10000328:file mytest.c, line 4. (gdb) s Cannot find bounds of current function I don't know why I cannot run the program at host side. Am I missing something? I am pretty new with "GDB" debug. Can some gurus give me some advices? Thanks very much. ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
