Hi Haavard Skinnemoen,

while you are working on atmel mci mmc driver, i would like to know whether you can tell me anything about the bug mentioned here

Possible Bug in at32ap mmc driver atmel_mci.c related to incorrect usage of variables.

Hmm...I think I missed that one. But yes, I think you found a bug.

The patch below should fix it. Normally, you won't actually see any difference because command CRC errors are quite rare, but we should at least try to do it correctly...

Make sure we check for CRC errors when sending commands that use CRC checking.
