Unfortunately, with my RTS522A I don't get as far as you do.
The very first CMD18 which reads 8192 bytes with a blocksize of 512 appears to
succeed. The MMC stack then immediately repeats the CMD18 which results in a
CRC error. After that ALL reads result in a CRC error no matter what the
transfer size is.
Looks like the soft reset is not clearing the CRC error. There must be a way
to do that, I would think.
Of course, the SD card itself might be the problem. I'll try a different card
and report back.
But at least /dev/mmcsd0 was created :)
