STM32H7S78-DK ETH and clock

roblahnst
Associate II

Board is STM32H7S78-DK

Serial: K242000883

CubeMX 6.14.0

TouchGFX Designer 4.25.0

CubeIDE 1.17.0

I load the STM32H7S78 Discovery Kit FreeRTOS example in TouchGFX Designer, design a screen and then open it in CubeIDE and flash it to the board. All fine. Then I open the .ioc file in CubeMX and activate ETH in Application and select the RMII mode. Immediately I get a Clock Configuration issue. The ETH CLOCK is only 24 MHz, but should be 50 MHz. When I click the button resolve clock issues I get a solution. I generate the Code (must enable USE_NEWLIB_REENTRANT) and flash the board with CubeIDE, but the Screen is dark. When I debug it goes into the Screen1View::setupScreen, but the Screen I designed in TouchGFX doesn't come up.
