I was trying to interface a microSD card (32GB) with STM32F407 through SDIO. Tried 1-bit and 4-bit modes. But it always gets me back FR_NOT_READY.
and the program always stuck here:
FATFS configuration:
SDIO configuration:
Clock:
Where I'm doing any mistake? Formated uSD card several times. Nothing improves. Do you have any suggestions?
