SDIO made some nasty problems in the last time. Needs decent rework.
Check wether to use https://git.shimatta.de/mhu/stm32f4-sdio as a basis.

  • Is DMA possible with current setup? Are the channels already used?
  • Increase SDIO clock speed. Check how this affects analog performance.

Sometimes f_open returns FR_INT_ERR which indicates a FAT error.

I suspect this is because I've tested the SD card for a longer time without reformatting it, and previous bugs during writing corrupted the FAT structure. Will keep an eye on that.
