Hi all
I'm new in implementing SD-Card, however i've managed to run the example from the repository. I am using STM32429i-Eval Board with cubeMX and CubeIDE.
Question is that when I run the example code on the board it works fine but when I create a new project (code generated by cubeMX) and copy the example code in it, the function f_mkfs() returns FA_NOT_READY error. All the hardware pin configurations are according to the schematic provided by the Eval-Board. Have a look at my code please.
