I can't add DMA to SDMMC

[EEuge]

Hello!

I have last version of CubeMX

I try to add DMA to SDMMC1

but I can't see "DMA" option sheet. How can I add DMA?

[EEuge]

And I can't see "SDMMC1" in listbox in DMA option page

[EEuge]

Important!

This error is only for STF32H743 chip

For example, F746 chip - I can add DMA for SDMMC1 without any problem

Hello @EEuge​ ,

It's not an issue, H7 using an Internal DMA (IDMA) contrary to F7, you can refer to RM for more details.

Best Regards,
