Hello, 

I would like to configure the DMA option for the SDMMC1 peripheral inside my STM32H747 microcontroller in order to communicate with an external SD in 4 bit wide bus mode using CubeMX, but the configuration setting doesn't appear among the configuration slots on the SDMMC1 panel. I was reading this link as reference. 

I also attached an image.

    Hello @AFato.3 ,

    For STM32H7, I advise you follow this AN5200 Getting started with STM32H7 MCUs SDMMC host controller.

    This document contains an STM32H7 example on how to configure the SDMMC using the STM32CubeMx tool.

    you still need to enable FATFS for the SD and it is there.
