Start Application Development
*****************************
Before powering up your M5Stack AtomS3, please make sure that the board is in good
condition with no obvious signs of damage.
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
-------------------
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_atoms3/esp32s3/procpu
:goals: build
The usual ``flash`` target will work with the ``m5stack_atoms3`` board
configuration. Here is an example for the :ref:`hello_world`
application.
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: m5stack_atoms3/esp32s3/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_atoms3
Debugging
---------
M5Stack AtomS3 debugging is not supported due to pinout limitations.
