SD Card SDIO not working(FR_DISK_ERR)

fs · ‎2024-01-18

I have a custom board and I have to run an SD card on it using SDIO protocol however on f_mount() function it takes a long time to come out with error FR_DISK_ERR but when I call "HAL_SD_GetCardInfo(&hsd, &sdCardSpace)" then I am getting all the data. I have tried with both 1-bit and 4-bit SDIO and DMA but none is working. I need help to figure out if its hardware error or software error or what the error is.

Hello @fs and welcome to the Community :),

Could you please precise, which STM32 device are you using?

Do you use the STM32CubeMX for code generation?

Thank you.

Also, try to check the SDcard on another device PC/laptop or others .. It could be an issue on the SDcard you are using!
