Resolved! STM32H7 Ethernet RMII reference clock can be input?
I have a board where STM32H743 is connected to a Microchip KSZ8873 for the PHY.In CubeMX generated code and examples, pin PA1 (RMII_REF_CLK) is configured as alt. function GPIO_AF11_ETH, mode GPIO_MODE_AF_PP.This works fine on eval. boards with a nor...
STM32H7 rev V vs Y DFU UART GO command issue
We have deployed quite a few of our products using STM32H753(ZIT6) rev Y and all was OK. All recent ones that we have around are rev V and they have issues with DFU bootloader over the UART. None of the issues that we have are listed in ERRATA notes ...
