Hi, FAT doesn't format a FS (I didn't enable) so it expects an already formatted FS. FAT is also not appropriate to use with Flash if that's what you're using, because it doesn't have a concept of "erase" and it doesn't do wear leveling. I actualy only tested with MMC!
I will do some testing today to try to find what is causing your problem with NFFS (or with no FS enabled). What FS operations are you doing? Are you using any of the fs_* calls? Could you copy/paste some of your FS usage code as a gist (or pastebin, etc)?
