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.
