USER MANUAL

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.

C:\Signum\SigGdbServer>SigGdbServer -cpu iMX31 -reg iMX31 -init

SigGdbServer Version 1.07 (C) Signum Systems Corp. 2006-2010

Waiting (romek2, 169.254.81.233):2000

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.
