Hello All,

I am using STM32F767ZI Nucleo Board. I am getting DCRCFAIL in data transfer using CMD53 in SDIO.

Any possible reason for CRC failure? Could there be any relation to clock out from SDMMC adapter?

I am able to see the 1st word in FIFO which seems to be correct. But not able read further bytes.

Are there any reference code for SDIO related commands like CMD52, CMD53?

regards,

Hemanth
