Configuring the Debugger
GNU GDB Debugger
Start the GDB server as described in the
Configuring the Server
section (page
3
). The server
should report a successful connection to the target processor.

Start the GDB debugger and execute the “target remote <host>:<port>” command to establish
a connection with the GDB server, as shown in the following examples.
Connecting to the server from a remote host computer named “labstation” via port 2000:
(gdb) target remote labstation:2000
Connecting to the server on the local machine:
(gdb) target remote localhost:2000
The server will report a successful connection. If GDB can read an XML target description from
a target, the server will load the available register definition files:
Connected from: (localhost, 127.0.0.1)
Loading registers from C:\Signum\SigGdbServer\targets\iMX31.def ...OK
Loading registers from C:\Signum\SigGdbServer\cores\ARM1136J-S.def ...OK
The following is an example of the initial stage of a typical remote debug session.
