Is there a simple way to use SDMMC1 an fatFS with NucleoH723 (I'm targetting H730 chip) polling or DMA

[Tbill.1]

I try the code bellow an ST youtube video, about F7, sdmmc and fat FS, but it's not working.

It seems to me there is no easy way about using SDMMC with H7.

the DMA setting are to complicated for my knowledge, but maybe I am missing some point.

Is there a simple way to use SDMMC and fatfs with H7 even in polling mode ?

Easy is a subjective term, high energy physics is hard, embedded software engineering, less so.

Is there a Nucleo-H7 example from ST, no, the board doesn't have an SD Card slot, but other ST DISCO/EVAL boards do, and these could perhaps be ported to your platform.

Ok thank you,

Do you know an application or a debrief about how to port a project on a new plateform ?

for ex, the STM32H735 project you show me in STM32H723 board.

Maybe it will be "easyer" on cube MX than in Cube IDE ?

What I do not understand when I open a package for cube IDE, is that there is no .ioc file.
