Subject: AW: [ECOS] Support of SD Card FAT problems with MBR
Date: Fri, 19 Apr 2013 14:01:00 -0000	[thread overview]
Message-ID: <018801ce3d06$68989010$39c9b030$@itrgmbh.de> (raw)

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.
