Default Zephyr Peripheral Mapping:

The FK723M1-ZGT6 board features one USB port, two 30x2 pin headers, one 4x2 debug header, one micro SD slot, one FPC10P LCD interface, one FPC20P Camera interface and one built-in external Quad SPI flash. The board is configured as follows:

UART_1 TX/RX : PA9/PA10 (debug header UART)
LD1 : PG7

System Clock

FK723M1-ZGT6 System Clock could be driven by an internal or external oscillator, as well as the main PLL clock. By default, the System clock is driven by the PLL clock at 550MHz, driven by an 15MHz high-speed external clock.

Serial Port

FK723M1-ZGT6 board has 4 UARTs and 4 USARTs. The Zephyr console output is assigned to UART1. Default settings are 115200 8N1.

Programming and Debugging

FK723M1-ZGT6 provides a special SWD header.

Flashing

The board is configured to be flashed using west STM32CubeProgrammer_ runner, so its :ref:installation <stm32cubeprog-flash-host-tools> is required.

Alternatively, OpenOCD or JLink can also be used to flash the board using the --runner (or -r) option:

.. code-block:: console

$ west flash --runner openocd $ west flash --runner jlink

Flashing an application to FK723M1-ZGT6

First, connect a SWD capable debugger to the debug header on FK723M1-ZGT6. Then connect the debugger to the host computer to prepare the board for flashing. Finally, build and flash your application.

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

Optional: Connect a USB-to-serial adapter to RX and TX (cross connect!).

.. code-block:: console

$ minicom -b 115200 -D /dev/ttyACM0

or use screen:

.. code-block:: console

$ screen /dev/ttyACM0 115200

Build and flash the application:

.. zephyr-app-commands:: :zephyr-app: samples/basic/blinky :board: fk723m1_zgt6 :goals: build flash

You should see the following messages on the console repeatedly:

.. code-block:: console

$ LED state: ON $ LED state: OFF
