I'm not using the Eval board for the project, so what I've done is remove MFX I/O related codes from BSP sd.c driver file. My MCU is STM32H743XI, and the base for the project, I modified the FatFS uSD standalone application example in Cube FW for H7 V1.2.0, for STM32H743I-EVAL board. I'm currently working on a project that needs to 'Read' a File in SDCARD.
