Thank you. Please let me know of anything I can do to help. Does this mean you are now able to duplicate the problem? The "Microsoft Extensible Firmware Initiative FAT32 File System Specification" white paper you quoted seems like a good reference document for FAT32. Is there anything better? BTW, in working with partitions <= 32MB, I have used FAT12, but fs/fat/fat.c clearly doesn't support FAT12 properly. FAT12 can be useful for NOR flash devices which are often small enough for all four primary partitions to be <= 32MB. Is anyone else (trying to) use FAT12 via U-Boot? My work-around for this problem has simply been force partitions <= 32MB to contain FAT16 whenever U-Boot needs to read file from them.
