    • SDIO FATFS Problem with STM32F4

    Posted by guden49 on 2017-11-30 10:08

    Hi everyone,
    It's been a week since I have started to working with SD Card. I watched many videos and did exactly same thing as they did but could't get any result.

    My code is being compiled and downloaded to flash succesfully. When I go with debug mode, MCU never returns FR_OK from f_mount function. It never creates

    volume in sd card. I have checked the hardware setup many times and everything seems ok. Code is very basic as well. What might cause that f_mount problem.

    I have also tried several reference projects and they didn't work as well. Could you send me a link for tested and working project for STM32F4 Discovery. This

    might help me to understand the problem.

    Thanks in advance

    Do you use HAL Library or Std Peripheral?
