Supported Features

.. zephyr:board-supported-hw::

Pin Mapping

FK743M5-XIH6 board has 5 GPIO controllers. These controllers are responsible for pin muxing, input/output, pull-up, etc.

Default Zephyr Peripheral Mapping

The FK743M5-XIH6 board is configured as follows

UART_1 TX/RX : PA9/PA10 (available on the header pins)
User LED (blue) : PC13
SPI5 NCS/CLK/MOSI : PE11/PE12/PE14 (SPI LCD)
QuadSPI NCS/CLK/IO0/IO1/IO2/IO3 : PG6/PF10/PF8/PF9/PF7/PF6 (NOR Flash)
USB DM/DP : PA11/PA12

System Clock

The FK743M5-XIH6 System Clock could be driven by an internal or external oscillator, as well as by the main PLL clock. By default the system clock is driven by the PLL clock at 480MHz, driven by an 25MHz external crystal oscillator.

Serial Port

The Zephyr console output is assigned to UART1. The default communication settings are 115200 8N1.

Programming and Debugging

.. zephyr:board-supported-runners::

Applications for the fk743m5_xih6 board target can be built and flashed in the usual way (see :ref:build_an_application and :ref:application_run for more details).

Flashing

The FK743M5-XIH6 board does not include an on-board debugger. As a result, it requires an external debugger, such as ST-Link, for programming and debugging purposes.

The board provides header pins for the Serial Wire Debug (SWD) interface.

Flashing an application to FK743M5-XIH6

To begin, connect the ST-Link Debug Programmer to the FK743M5-XIH6 board using the SWD interface. Next, connect the ST-Link to your host computer via a USB port. Once this setup is complete, you can proceed to build and flash your application to the board

Here is an example for the :zephyr:code-sample:hello_world application.

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: fk743m5_xih6 :goals: build flash

Run a serial host program to connect with your board:

.. code-block:: console

$ minicom -D /dev/ttyACM0 -b 115200

Then, press the RESET button, you should see the following message:

.. code-block:: console

Hello World! fk743m5_xih6

Debugging

You can debug an application using the SWD interface with a J-Link or ST-Link. For more details, please refer to the Flashing_ section and run the west debug command instead of west flash.

Here is an example for the :zephyr:code-sample:hello_world application.

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: fk743m5_xih6 :goals: debug :flash-args: -r pyocd :compact:
