AW: Support of SD Card FAT problems with MBR

["Richard Rauch" <rrauch at itrgmbh dot de>]

Sorry, I was wrong...seems that there is a MBR..I mismatched MBR and FAT
partition's boot sector.
We had a problem with wrong device name, so the driver accessed block 0 on
SD Card instead of first block of partition.
