For that, as I understand, we need to use different driver/service layers (SDCard Driver, disk driver, FAT file system) Low level driver works already, but seems that there are problems with data structures on Disk. Is it true, that SDCards formatted without MBR? We are using SD Cards, which are formatted under Windows (what seems to be mostly common) But when mounting the SDCard within eCos, seems it fails, because no MBR is found on SDCard. Am I wrong? Or do we need to do something special with SDCard, Disk, or FAT Drivers?
