|
System requirements |
|
=================== |
|
|
|
Prerequisites |
|
------------- |
|
|
|
Espressif HAL requires WiFi and Bluetooth binary blobs in order work. Run the command |
|
below to retrieve those files. |
|
|
|
.. code-block:: shell |
|
|
|
west blobs fetch hal_espressif |
|
|
|
.. note:: |
|
|
|
It is recommended running the command above after :file:`west update`. |
|
|
|
Building & Flashing |
|
------------------- |
|
|
|
.. zephyr:board-supported-runners:: |
|
|
|
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: m5stack_atom_lite/esp32/procpu |
|
:goals: build |
|
|
|
The usual ``flash`` target will work with the ``m5stack_atom_lite`` board |
|
configuration. Here is an example for the :zephyr:code-sample:`hello_world` |
|
application. |
|
|
|
.. zephyr-app-commands:: |
|
:zephyr-app: samples/hello_world |
|
:board: m5stack_atom_lite/esp32/procpu |
|
:goals: flash |
|
|
|
The baud rate of 921600bps is set by default. If experiencing issues when flashing, |
|
try using different values by using ``--esp-baud-rate <BAUD>`` option during |
|
``west flash`` (e.g. ``west flash --esp-baud-rate 115200``). |
|
|
|
You can also 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! m5stack_atom_lite |
