Hi,
I am using the STM32F407VG and try to read an SD Card over SDIO in 4 bit mode.
I have downloaded the fatfs driver from this site:

Posted on May 18, 2018 at 15:29 I attached a minimal project of my problem. May be someone can take a look over it.

Now I figured out, the second check_fs-call isn't working because theHAL_SD_IRQHandler-interrupt-function isn't setting the hsd->SdTransferCplt = 1U; due to a CRC error. So the SD_DMA_RxCplt-interrupt-functionends ...
