The file system of this version is incompatible to earlier versions and existing file systems on the hardware MUST be RE_FORMATTED to be usable again.
This also effects the useable FIRMWARE versions. Only FIRMWARE files with the same file system version are usable.
When upgrading your system, working in "Usecase C" (using a file system on external FLASH), from a Maintenance firmware with version < V1.3.0.0 to version V1.3.0.0 or higher, it is necessary to re-format (full format) an existing file system to enable the FTL / Wear leveling function!
