Currently we do no have a maintainer for the FAT file system. Takahiro has done a great job fixing some of the most prominent deficiencies. But still the driver is not in good shape:
I once again ran upon errors in FAT when executing the UEFI SCT.
Here is some of the output of dosfsck -w -r -l -a -v -t The full output has hundreds of errors recorded.

BareBox is using a (somewhat outdated) copy of this library with a little bit of wrapper code:
FatFs - Generic FAT Filesystem Module http://elm-chan.org/fsw/ff/00index_e.html http://elm-chan.org/fsw/ff/arc/ff13c.zip
The same library is also used for Arduinos: https://github.com/stm32duino/FatFs
Shouldn't we try just the same?
I think that or similar has been suggested before. Are you volunteering to maintain the wrapper and keep it in-sync? Thanks!
