stm32h7
|
|
=======
|
|
|
|
This BSP supports the
|
|
`STM32H7 Series <https://www.st.com/en/microcontrollers-microprocessors/stm32h7-series.html>`_.
|
|
|
|
The BSP is known to run on these boards:
|
|
|
|
* `STM32H743I-EVAL 2 <https://www.st.com/en/evaluation-tools/stm32h743i-eval.html>`_
|
|
* `STM32H743ZI-Nucleo <https://www.st.com/en/evaluation-tools/nucleo-h743zi.html>`_
|

|
Clock Driver
|
|
------------
|
|
|
|
The clock driver uses the `ARMv7-M Systick` module. The HSE (external
|
|
oscillator) value can also be different for different evaluation or custom
|
|
boards, so it is recommended to check the default values of the BSP.
|
|
|
|
Console Driver
|
|
--------------
|
|
|
|
The console driver supports the on-chip UART and USART modules.
|
|
Different board variations use different GPIO pins and blocks for the default
|
|
communication UART and it is recommended to check whether the default
|
|
configuration provided is valid in the BSP.
|
|
|
|
To specify that the BSP should be built for the STM32H743ZI-Nucleo board,
|
|
users can supply ``STM32H743ZI_NUCLEO = True`` to ``config.ini`` when
|
|
building the BSP.
|
|
|
|
Alternatively, users can supply the configuration structs defined in ``hal.h``
|
|
in the application for other boards. For the console driver, the
|
|
``stm32h7_usartX_config`` structs are used to configure the GPIO pins and other
|
|
parameters. The default implementations can be found in
|
|
``bsps/arm/stm32ht/console`` in the RTEMS sources.
|
|
|
|
Network Interface Driver
|
|
------------------------
|
|
|
|
The network interface driver ``if_stmac`` is provided by the ``libbsd``.
|
|
|
|
USB Host Driver
|
|
---------------
|
|
|
|
The USB host driver ``dwc_otg`` is provided by the ``libbsd``.
