Programming and Debugging
|
|
*************************
|
|
|
|
Please refer to
|
|
:ref:`Programming and Debugging EFR32 Radio Board <efr32_radio_programming>`
|
|
for details on the supported debug interfaces.
|
|
|
|
Flashing
|
|
========
|
|
|
|
Connect the BRD4001A board with a mounted BRD4255A radio module to your host
|
|
computer using the USB port.
|
|
|
|
Here is an example for the :ref:`hello_world` application.
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/hello_world
|
|
:board: efr32_radio/efr32fg13p233f512gm48
|
|
:goals: flash
|
|
|
|
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 see the following message in the terminal:
|
|
|
|
.. code-block:: console
|
|
