How to configure sdmmc for SD card in stm32h7s7 with FATFS

[ropodi17]

Hi,

Im trying to configure SDMMC 4 wide bus with FATFS for SD card.

Im not able to see any DMA options or Platform setting to set SD detect GPIO pin.

am I missing something? I have refered through most of the documentation and tutorials online but with this MCU there is no options for DMA or Platform settings menu in .ioc configuration.
Could you please help me with a procedure to setup SDMMC and FATFS for this MCU?
Thanks

Hello @ropodi17 

The SDMMC peripheral on the STM32H7 series have its own internal DMA controller.
