Can we please have an option in CubeMX for interfacing with fatfs over spi for microcontrollers that don't have a sdio interface? Alternatively has anybody out there written a user_diskio.c and user_diskio.h that i could use? thanks

what would I need to do in order to use this code with a project generated under CubeMX?

I guess you'd need to figure out how it uses BSP or user/template code in other circumstances, and then apply that to your board. Sorry I don't CubeMX

For others stuck in this position i found kiwih's drivers very useful, it's an easy drop in implementation for existing CubeMX projects.
