| 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 BRD4002A board with a mounted BRD4187C 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_brd4187c |
| :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 |
| |
