Embedded Programming with Modern C++ Cookbook

How to do it...

We have learned how to copy an application to the target system and run it there. Now, let's learn how to start debugging an application on a target system using GDB. In this recipe, we will only learn how to invoke the debugger and run applications in the debugger environment. It will be used as a foundation for more advanced and practical debugging techniques later:

1. Switch to the QEMU window.
2. If you have not done so already, log in using pi as the username and raspberry as the password.
3. Run the following command:

$ gdb ./hello

4. This will open the gdb command line.
5. Type run to run the application:

(gdb) run

5. You should see Hello, world in the output.
6. Now, run the quit command, or just q:

(gdb) q

This terminates the debugging ...
