49Programming and Debugging
50=========================
51
52Flashing an application
53-----------------------
54
55Connect your device to your host computer using the JLINK USB port.
56The sample application :zephyr:code-sample:`hello_world` is used for this example.
57Build the Zephyr kernel and application, then flash it to the device:
58
59.. zephyr-app-commands::
60   :zephyr-app: samples/hello_world
61   :board: apollo3p_evb
62   :goals: flash
63
64.. note::
65   ``west flash`` requires `SEGGER J-Link software`_ and `pylink`_ Python module
66   to be installed on you host computer.
67
68Open a serial terminal (minicom, putty, etc.) with the following settings:
69
70- Speed: 115200
71- Data: 8 bits
72- Parity: None
73- Stop bits: 1
74
75Reset the board and you should be able to see on the corresponding Serial Port
76the following message:
77
78.. code-block:: console
79
