boards: M5Stack Core2 module suppport
This Pull-Request enables support for the M5Stack Core2 hardware. The module features a LCD display, touchscreen, battery, USB-Port, 8MB RAM and 16MB Flash. Basic features are working. Please refere to the board documentation for details. Signed-off-by: Martin Kiepfer <mrmarteng@teleschirm.org> gpio: gpio_axp192: fix dependecy between GET_DIRECTION and GET_CONFIG configuration Latest unit gpio get_direction unit test failes, as get_direction api internally requires get_config functionality. This commit fixes this dependecy. Signed-off-by: Martin Kiepfer <m.kiepfer@teleschirm.org>

*****************************
|
||||
|
||||
Before powering up your M5Stack Core2, 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:: 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: m5stack_core2
|
||||
:goals: build
|
||||
|
||||
The usual ``flash`` target will work with the ``m5stack_core2`` board
|
||||
configuration. Here is an example for the :ref:`hello_world`
|
||||
application.
|
||||
|
||||
.. zephyr-app-commands::
|
||||
:zephyr-app: samples/hello_world
|
||||
:board: m5stack_core2
|
||||
: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_core2
|
||||
|
||||
Debugging
|
||||
---------
|
||||
|
||||
M5Stack Core2 debugging is not supported due to pinout limitations.
