Summary
- FatFs library upgrade
- Saving of self-test results
This is the second release candidate of the upcoming firmware 4.3.2. The current focus is on bug fixes related to the USB Flash drivers.
FatFs library upgrade
Compared to the previous release RC1, this build brings an upgrade of the FatFs library, which is supposed to fix synchronization issues of accessing the file system.
FatFs library has been upgraded from R0.12c to the latest version of R0.14b. The most important change is the fix of synchronization issues related to accessing the FAT file system. Please see the release notes of the FatFs library for details, where the synchronization fix is also discussed.
This also fixed several reported situations of BSOD after the removal of the USB drive from the MINI and MINI+.
Moreover, to improve the quality of testing of the USB drivers and file system fixes, we designed an automated device that simulates various edge cases while inserting and/or removing a USB drive. The testing device helped us to verify that the fix works as expected.
Please let us know if you still encounter problems with the USB drives.
Saving of self-test results
The upgrade of the FatFs library also brings back the possibility of saving results of self-tests onto the USB drive (if present), which has been removed in previous versions due to random file system-related problems.
