The OpenH743I-C is an STM32 development board with STM32H743IIT6.
|
|
It comes with a rich expansion interface to support access to various
|
|
peripheral modules.
|
|
|
|
.. note:: This board has very poor signal integrity.

Peripherals
|
|
===========
|
|
|
|
SDMMC
|
|
-----
|
|
|
|
The SDMMC1 interface seems not to work correctly with clock frequencies higher
|
|
than 20 MHz.
|
|
|
|
USBHS
|
|
-----
|
|
|
|
The reset pin on the ULPI port must be connected to the PE2 pin of the MCU.
|
|
If it's not connected, ULPI interface may not work correctly without power reset.
