| System requirements |
| ******************* |
| |
| Prerequisites |
| ------------- |
| |
| Espressif HAL requires WiFi and Bluetooth binary blobs in order work. Run the command |
| below to retrieve those files. |
| |
| .. code-block:: console |
| |
| west blobs fetch hal_espressif |
| |
| .. note:: |
| |
| It is recommended running the command above after :file:`west update`. |
| |
| Building & Flashing |
| ------------------- |
| |
| Build and flash applications as usual (see :ref:`build_an_application` and |
| :ref:`application_run` for more details). |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/hello_world |
| :board: esp32s2_franzininho |
| :goals: build |
| |
| The usual ``flash`` target will work with the ``esp32s2_franzininho`` board |
| configuration. Here is an example for the :ref:`hello_world` |
| application. |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/hello_world |
| :board: esp32s2_franzininho |
| :goals: flash |
| |
| Open the serial monitor using the following command: |
| |
| .. code-block:: shell |
| |
| west espressif monitor |
| |
| After the board has automatically reset and booted, you should see the following |
| message in the monitor: |
| |
| .. code-block:: console |
| |
| ***** Booting Zephyr OS vx.x.x-xxx-gxxxxxxxxxxxx ***** |
| Hello World! esp32s2_franzininho |
