I'm trying to add FATFS to by CubeMX project targeting the STM32F767 processor. Even though I've enabled the SDMMC1 interface the only FATFS mode I can tick is 'User-defined'. Why is the 'SD Card' greyed.

Hello @Community member​ ,

It depends on your configuration, you should to active SD mode with SDMMC IP. 

There is a tooltip in CubeMx that can guide you as shown below:

Imen, thanks for that, I had it in MMC 4 bit mode and hadn't noticed the SD 4 bit mode. The screen shot you've posted is interesting because it shows tool tips. I hadn't noticed any tool tips and on investigation on my PC it's very reluctant to show them.
