issue with interfacing external emmc

I’m interfacing the STM32H755ZI-Q Nucleo board with an MTFC8GAMALNA-AAT eMMC. What configurations are necessary for this interfacing? I’m also getting warnings in the RCC configurations. Could you guide me on the settings needed for SDMMC1 and FATFS, and let me know if there are any additional configurations required?

Hi @Ismails 

Have a look at this AN5200 "Getting started with STM32H7 Series SDMMC host controller", which contains typical examples and it may help you on the SDMMC and FATFS configuration.

Thank you.
