Hi, i'm using Stm32f746zg nucleo-144 board and i want to work with sd card communication, as i see on internet there are some examples about f4 but i did not work with sd card. ?f anybody tried something about sd card in F7 or would you like to share projects about sdmmc1.

I'm sure, you can use most of the Drivers for STM32L4/F4 or other Controllers with SDMMC also for your STM32F7. Only the real LowLevel-Drivers could be different and they come from Cube and I would suggest you to not change them. The above Layers must be fixed to your Needs. The only half-working Example from STM are the one Part of the CubeL4-FW for the big and expansive STM32-L476-Eval-Board. All other Examples for F4/L4 as far as I know (and I tested a lot) do not work. The generated Code is also not working. So use the one from the big L476-Eval-Board. Most important for you is the diskio-Layer.

You can also take a look into some Informations around SDMMC for L4 in this Thread:

You should arrange some time for getting it to work stable and fast ...
