JFFSx is a file system. That will not do what you want. What you need is some block-like FTL like NFTL or whatever goes on inside a Compact Flash or ATA card. I am not aware of any open source code that will do what you want. As far as I can tell all this code is fiercely guarded by companies like Sandisk and MSystems. Maybe someone can be more helpful..... -- CHarles On Wed, 01 Jan 2003 08:42, Jeff Lin wrote: > Hello, all, > > First, Happy new year to you! > > I am looking for a FTL (flash translation layer)code > that will emulates the flash memory as a IDE disk > for the controller IC inside the compact flash card. > > The FTL will need to do logical to physical address > mapping, bad block management, and wear level > algorithm.
