You can run GDB, the GNU Debugger, on your host system to debug programs running remotely on a target board or system.
While this section explains the alternatives for using GDB to run and debug application programs, explaining the use of the GDB command-line interface is beyond the scope of this document. Please refer to the GDB manual for further instructions.
From within GDB, you can connect to a running gdbserver or other debugging stub that uses the GDB remote protocol using:
(gdb) target remotehost
:port
where host
is the host name or IP address of the
machine the stub is running on, and port
is the
port number it is listening on for TCP connections.
