Programming and Debugging
|
|
*************************
|
|
|
|
Applications for the ``nucleo_l433rc_p`` board configuration can be built and
|
|
flashed in the usual way (see :ref:`build_an_application` and
|
|
:ref:`application_run` for more details).
|
|
|
|
Flashing
|
|
========
|
|
|
|
Nucleo L433RC-P board includes an ST-LINK/V2-1 embedded debug tool
|
|
interface. This interface is supported by the openocd version
|
|
included in the Zephyr SDK since v0.9.2.
|
|
|
|
Flashing an application to Nucleo L433RC-P
|
|
------------------------------------------
|
|
|
|
Connect the Nucleo L433RC-P to your host computer using the USB port,
|
|
then run a serial host program to connect with your Nucleo board.
|
|
|
|
.. code-block:: console
|
|
|
|
$ picocom /dev/ttyACM0 -b 115200
|
|
|
|
Now build and flash an application. Here is an example for
|
|
:ref:`hello_world`.
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/hello_world
|
|
:board: nucleo_l433rc_p
|
|
:goals: build flash
|
|
|
|
You should see the following message on the console:
|
|
|
|
.. code-block:: console
|
|
|
|
$ Hello World! nucleo_l433rc_p
|
|
|
|
|
|
Debugging
|
|
=========
|
|
|
|
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: nucleo_l433rc_p
