Hallo,
I can't find any info about this theme!
Can someone please help me with some hints on how to "connect" FATFS as filesystem driver with the SDMMC1 interface (in 4 bits mode) as hardware.
Many Thanks in advance,
Michael

In that case you can refer to the example provided in STM32CubeH7 under the path Projects\STM32H743I-EVAL\Applications\FatFs\FatFs_uSD_Standalone

Hello @Mick P. F. ,
Please refer to this video (from t= 2:03) on YouTube done for F7, normally it would be the same steps: link.
Hope this will help you.

Hello SofLit,
I have found some projects and examples on this topic, but they all relate to the STM32F MCUs.
There are two problem with this: When I activate FATFS in STM32CubeMX, I can only select the "User defined" mode but not "SD Card". In addition, SDMMC1 of the H7 is not DMA capable inside STM32CubeMX (in contrast to STM32F).
I have now decided to access the SD card via SPI because it is easier and I only want to read a little couple of data.
Thanks for your help.
