3.2.1 Starting the GDB Server on the Target

In this passage you will learn how to start the GDB server on the target. The GDB server will be used to start and control the myHelloWorld program.

To debug a program with GDB, the program needs extended debugging symbols. These have already been added while building the program.

ƒ

Open Microcom.

ƒ

Type root  and press Enter.

ƒ

Start the GDB server: gdbserver 192.168.3.11:10000 myHelloWorld

You have started the GDB server on the target. The GDB server is now waiting for connections on TCP port 10000.

3.2.2 Configuring and Starting the Debugger in Eclipse
