Building and Flashing
*********************
Flashing
========

Here is an example for the :ref:`hello_world` application.

.. zephyr-app-commands::
   :zephyr-app: samples/hello_world
   :board: xmc45_relax_kit
   :goals: flash

Debugging
=========

Here is an example for the :ref:`hello_world` application.

.. zephyr-app-commands::
   :zephyr-app: samples/hello_world
   :board: xmc45_relax_kit
   :goals: debug

Step through the application in your debugger.
