Configuration of SDMMC+DMA using STM32H750VBT6 with SDFAT ?

Recently, I was trying to implement SDMMC+DMA+SDFAT to read and write the SD card of my Class on the STM32H750VBT6. Then I found that the DMA of SDMMC was gone. I saw some online materials saying that MDMA needs to be configured, and some also said that SDMMC does not need to configure DMA as it has its own independent IDMA bus. What is the actual situation when it is directly mounted on AHB? Are there any configuration screenshots and programs of CubeMX for SDMMC+DMA? I'd like to refer to it. Thank you!

Hello @ChenJingtai 

You can refer to the SD_ReadWrite_DMA example in STM32CubeH7. Although this example does not include an .ioc file, you can use its SDMMC configuration as a reference to set up your MX configuration.
