[STM32H7] How to read and write an SD card in DMA mode?

[Cai]

Hello Community,

I'm working on a storage module using SDcard for my project.

The chip I'm using is STM32H743XIH6.
At present, the SD card has been successfully read and written in the polling (ordinary) mode. However, I have never succeeded in reading and writing the SD card in DMA mode.
Could you please provide a complete illustrated tutorial of the configuration process?
For now, there is no need to introduce fatfs. Just read and write a block in DMA mode.
If possible, please also provide a configured.ioc file and the test code.

PS:

STM32CubeMX Version: 6.14.1

Hello @Cai and welcome to the community,

Did you already refer to the example provided by the STM32CubeH7 package under this link: Projects/STM32H743I-EVAL/Applications/FatFs/FatFs_uSD_DMA_Standalone
