Supported Features
61+
==================
62+
63+
.. zephyr:board-supported-hw::
64+
65+
Default Zephyr Peripheral Mapping:
66+
----------------------------------
67+
68+
The FK723M1-ZGT6 board features one USB port, two 30x2 pin headers, one 4x2 debug header,
69+
one micro SD slot, one FPC10P LCD interface, one FPC20P Camera interface and one built-in external Quad SPI flash.
70+
The board is configured as follows:
71+
72+
- UART_1 TX/RX : PA9/PA10 (debug header UART)
73+
- LD1 : PG7
74+
75+
System Clock
76+
------------
77+
78+
FK723M1-ZGT6 System Clock could be driven by an internal or external
79+
oscillator, as well as the main PLL clock. By default, the System clock is
80+
driven by the PLL clock at 550MHz, driven by an 15MHz high-speed external clock.
81+
82+
Serial Port
83+
-----------
84+
85+
FK723M1-ZGT6 board has 4 UARTs and 4 USARTs. The Zephyr console output is
86+
assigned to UART1. Default settings are 115200 8N1.
87+
88+
Programming and Debugging
89+
*************************
90+
91+
FK723M1-ZGT6 provides a special SWD header.
92+
93+
Flashing
94+
========
95+
96+
The board is configured to be flashed using west `STM32CubeProgrammer`_ runner,
97+
so its :ref:`installation <stm32cubeprog-flash-host-tools>` is required.
98+
99+
Alternatively, OpenOCD or JLink can also be used to flash the board using
100+
the ``--runner`` (or ``-r``) option:
101+
102+
.. code-block:: console
103+
104+
$ west flash --runner openocd
105+
$ west flash --runner jlink
106+
107+
Flashing an application to FK723M1-ZGT6
108+
----------------------------------------
109+
110+
First, connect a SWD capable debugger to the debug header on FK723M1-ZGT6.
111+
Then connect the debugger to the host computer to prepare the board for flashing.
112+
Finally, build and flash your application.
113+
114+
Here is an example for the :zephyr:code-sample:`blinky` application.
115+
116+
Optional: Connect a USB-to-serial adapter to RX and TX (cross connect!).
117+
118+
.. code-block:: console
119+
120+
$ minicom -b 115200 -D /dev/ttyACM0
121+
122+
or use screen:
123+
124+
.. code-block:: console
125+
126+
$ screen /dev/ttyACM0 115200
127+
128+
Build and flash the application:
129+
130+
.. zephyr-app-commands::
131+
:zephyr-app: samples/basic/blinky
132+
:board: fk723m1_zgt6
133+
:goals: build flash
134+
135+
You should see the following messages on the console repeatedly:
136+
137+
.. code-block:: console
138+
139+
$ LED state: ON
140+
$ LED state: OFF
141+
142+
Hello World example can also be used:
143+
144+
.. zephyr-app-commands::
145+
:zephyr-app: samples/hello_world
146+
:board: fk723m1_zgt6
147+
:goals: build flash
148+
149+
Debugging
150+
=========
151+
152+
You can debug an application in the usual way. Here is an example for the
153+
:zephyr:code-sample:`hello_world` application.
154+
155+
.. zephyr-app-commands::
156+
:zephyr-app: samples/hello_world
157+
:board: fk723m1_zgt6
158+
:maybe-skip-config:
159+
:goals: debug
