System Clock
============
The STM32F7508 System Clock can 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 216MHz, driven by a 25MHz high speed external clock.
Serial Port
===========
The STM32F7508-DK Discovery kit has up to 8 UARTs. The Zephyr console output is assigned to UART1
which connected to the onboard ST-LINK/V2 Virtual COM port interface. Default communication
settings are 115200 8N1.
Programming and Debugging
*************************
STM32F7508-DK Discovery kit includes an ST-LINK/V2 embedded debug tool interface.
Applications for the ``stm32f7508_dk`` board configuration can be built and
flashed in the usual way (see :ref:`build_an_application` and
:ref:`application_run` for more details).
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 STM32F7508-DK
-------------------------------------------
First, connect the STM32F746G Discovery kit to your host computer using
the USB port to prepare it for flashing. Then build and flash your application.
Here is an example for the :zephyr:code-sample:`hello_world` application.
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: stm32f7508_dk
:goals: build flash
Run a serial host program to connect with your board:
.. code-block:: console
$ minicom -D /dev/ttyACM0
You should see the following message on the console:
.. code-block:: console
Hello World! arm
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: stm32f7508_dk
