Programming and Debugging
|
|
||||||
*************************
|
|
||||||
|
|
||||||
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 nRF52 DK
|
|
||||||
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: nrf52dk_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 nRF52 DK
|
|
||||||
********************************************
|
|
||||||
|
|
||||||
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/arm/nrf52dk_nrf52832/nrf52dk_nrf52832.dts`.
