| Flashing |
| ======== |
| |
| Connect the BRD4001A board with a mounted BRD4170A 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/efr32mg12p433f1024gm68 |
| :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: |
