*****************************
|
|
|
|
Before powering up your M5Stack ATOM Lite, 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_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 :ref:`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

|
Debugging
|
|
---------
|
|
|
|
M5Stack ATOM Lite debugging is not supported due to pinout limitations.
