Anybody have an example of using the mci_sync_* methods to initialize an SD card? I've got an Atmel Start project going. I've done SD card in SPI mode before, but part of the whole purpose of this chip is the ability to use 4 bit mode. Every command I send gives back a 0 from mci_sync_get_response(), so I have little confidence that it's actually talking to the card properly.
