+Supported Features
+==================
+
+.. zephyr:board-supported-hw::
+
+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
+
+Hello World example can also be used:
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/hello_world
+   :board: fk723m1_zgt6
+   :goals: build flash
+
+Debugging
+=========
+
+You can debug an application in the usual way.  Here is an example for the
+:zephyr:code-sample:`hello_world` application.
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/hello_world
+   :board: fk723m1_zgt6
+   :maybe-skip-config:
+   :goals: debug
