Configure SDMMC2 for H743VIT6

[ksale.1]

Hi,

1- How do I let CubeMX know the SD pin detect, I've set pin PC13 as card_detect, GPIO input, pull-up, but then what?

2- Should I use the open source FATFS "https://elm-chan.org/fsw/ff/00index_e.html"? How?

Thank you

Hi,

Please refer to AN5200 Getting started with STM32H7 Series SDMMC host controller.

Also, you can refer to the provided example which perform some write and read transfers to SD Card with SDMMC. Available in STM32CubeH7 firmware via this link

Thank you @Bouraoui Chemli​ ,

Please note the slight difference between AN5200 MDMA config and my CubeMX MDMA, as shown in figure below:
