When a SD card is initialized some data transfers of 64 and 8 bytes are issued. It seems the DMA has some problems dealing with these kind of "short" transfers, leading sometimes to the SD card not being detected. In order to solve this problem, do not use DMA for transfer sizes lower than the sector size.
