In the mci-core.c source file you can enable the DEBUG macro to include more
debug output. This will print more information about the MCI card detection.
Maybe it helps.
Check also:
- pin multiplexing
- power supply to the SD card
- GPIOs for detecting the SD card (some kind of inserting signal)
- increase the min frequency to about 400 kHz. Maybe 1476 Hz are too slow and
conflict with some timeout values
Regards,
Juergen
