FatFs R0.16 has been released on July 22, 2025. These are the verified problems about FatFs R0.16 and its workaround or patch.
2. September 13, 2025 -------------------------------------------------------------------------------------------------- From a suggestion in user forum, I have changed the minimum volume size from 128 sectors to 64 sectors. This is the patch-1 for ff.c without patch. When create a volume on the very small drive with f_mkfs function, it is recommended to specify FM_SFD flag and set a proper value to n_root.
1. August 3, 2025 -------------------------------------------------------------------------------------------------- The Unicode conversion module, ffunicode.c, linked at LFN configuration occupies a large amount of memory when it is configured for DBCS. From a suggestion in user forum, I have found that there is much room for improvement of the compression ratio of 6 out of 8 conversion tables. This is the result in table size by modification of compression algorithm. Japanese (932) 59k ==> 47k (-12k) Simplified Chinese (936) 174k ==> 97k (-77k) Korean (949) 136k ==> 103k (-33k) Traditional Chinese (950) 108k ==> 78k (-30k) All CP (0) 482k ==> 329k (-153k) This is the new code for replacement. Note that there is no improvement for SBCS configurations.
