STM32F401RE Nucleo + SDIO + FatFS + CubeMX 4.21.0, anyone can confirm me that SD is working and CubeMx dont'create fault code? I'm trying to write a file in SD card but at f_printf(....) CPU still locked (hard fault?)

I have increased size heap at 0x400 and stack 0x800
Solved thanks to Buffer overflow in CubeMX SDMMC-Driver
