Does the TargetFAT file system include routines to support RAM drives?
TargetFAT is shipped with a RAM driver that allows you to verify and test your file system integration before addressing the driver layer. Also, with each of our file system products, we include a RAM based file system, TargetRFS, that calls malloc() and free() as files are created/grown or deleted. The first option (RAM driver) gives you a fixed-size footprint for the RAM volume you create. The second option (TargetRFS) starts with a 0 footprint that grows/shrinks according to your application use. Depending on your requirements, one may be preferable over the other. Robustness of the FAT file system (power down, hot (un)plug of a flash card) is becoming important for us. Your documentation states “Robust, performs automatic power-fail recovery during mount.” What exactly does you implementation guarantee? For instance, does it guarantee that directory entries and FATs are consistent? TargetFAT implementation does guarantee that directory and FAT entries are consistent. We use two FAT
