Debugging

=========



   You should see "Hello World! arm" in your terminal.

You can debug an application in the usual way.  Here is an example for the

:ref:`hello_world` application.



.. zephyr-app-commands::

   :zephyr-app: samples/hello_world

   :board: sam4s_xplained

   :maybe-skip-config:

   :goals: debug
