--- FAT16 vs. FAT32 - Atmel U-Boot v1.1.5 issue? ---
I have found that the USB support is better when the USB Storage device is FAT16 formatted rather than FAT32 formatted. For some reason not all files were accessible on FAT32 formatted media, but I never had any problem with FAT16 formatted media.
Can you try this patch? In the git log there is another patch for vfat to be applied.
Check if the entry is a valid dir_slot entry, otherwise it is a dentry and the name has to be taken by the get_name function

I tried it, but it did not work.
I also tried the earlier patch where Michael Trimarchi added the CHECK_CLUST() macro, but it still doesn't work.
Next, I compared my fs/fat/fat.c with what was in git a few hours ago. The only significant differences were in the fat_register_device(), but after making my fs/fat/fat.c match what's in git (except for trivial whitespace differences and recent CONFIG_* & CFG_* handling differences, it still fails to work properly.
