Programming and Debugging
*************************

Flashing
========
The byteSENSI-L board can be flashed with the SEGGER JLink programmer.

You can build and flash applications in the usual way. Here is an example for
the :ref:`hello_world` application.

   .. zephyr-app-commands::
      :zephyr-app: samples/hello_world
      :board: bytesensi_l
      :goals: build flash
      :compact:

Debugging
=========

Debugging your application can be done with ``west debug``.

Serial console
==============

The byteSENSI-L board only uses Segger's RTT console for providing serial
console. There is no physical serial port available.
