Programming and Debugging
|
|
=========================
|
|
|
|
Flashing an application
|
|
-----------------------
|
|
|
|
Connect your device to your host computer using the JLINK USB port.
|
|
The sample application :ref:`hello_world` is used for this example.
|
|
Build the Zephyr kernel and application, then flash it to the device:
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/hello_world
|
|
:board: apollo3_evb
|
|
:goals: flash
|
|
|
|
.. note::
|
|
`west flash` requires `SEGGER J-Link software`_ and `pylink`_ Python module
|
|
to be installed on you host computer.
|
|
|
|
Open a serial terminal (minicom, putty, etc.) with the following settings:
|
|
|
|
- Speed: 115200
|
|
- Data: 8 bits
|
|
- Parity: None
|
|
- Stop bits: 1
|
|
|
|
Reset the board and you should be able to see on the corresponding Serial Port
|
|
the following message:
|
|
|
|
.. code-block:: console
