Programming and Debugging
|
|
*************************
|
|
|
|
Applications for the ``we_proteus2ev/nrf52832`` board configuration can be
|
|
built, flashed, and debugged in the usual way. See
|
|
:ref:`build_an_application` and :ref:`application_run` for more details on
|
|
building and running.
|
|
|
|
Flashing
|
|
========
|
|
|
|
Follow the instructions in the :ref:`nordic_segger` page to install
|
|
and configure all the necessary software. Further information can be
|
|
found in :ref:`nordic_segger_flashing`. Then build and flash
|
|
applications as usual (see :ref:`build_an_application` and
|
|
:ref:`application_run` for more details).
|
|
|
|
Here is an example for the :ref:`hello_world` application.
|
|
|
|
First, run your favorite terminal program to listen for output.
|
|
|
|
.. code-block:: console
|
|
|
|
$ minicom -D <tty_device> -b 115200
|
|
|
|
Replace :code:`<tty_device>` with the port where the board Proteus-II-EV
|
|
can be found. For example, under Linux, :code:`/dev/ttyACM0`.
|
|
|
|
Then build and flash the application in the usual way.
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/hello_world
|
|
:board: we_proteus2ev/nrf52832
|
|
:goals: build flash
|
|
|
|
Debugging
|
|
=========
|
|
|
|
Refer to the :ref:`nordic_segger` page to learn about debugging Nordic boards with a
|
|
Segger IC.
|
|
|
|
|
|
Testing the LEDs and buttons in the Proteus-II-EV
|
|
*************************************************
|
|
|
|
There are 2 samples that allow you to test that the buttons (switches) and LEDs on
|
|
the board are working properly with Zephyr:
|
|
|
|
.. code-block:: console
|
|
|
|
samples/basic/blinky
|
|
samples/basic/button
|
|
|
|
You can build and flash the examples to make sure Zephyr is running correctly on
|
|
your board. The button and LED definitions can be found in
|
|
:zephyr_file:`boards/we/proteus2ev/we_proteus2ev_nrf52832.dts`.
