I think it's possible to run yaffs-direct under Linux, but a) not from scratch, so you'll need to do additional mods and b) i'm not sure it's legal from a licensing POV. The performance drop is only a problem for 512b page NAND flashes, so if you've got a 2k page Samsung NAND flash, you shouldn't probably bother. The last thing I'd like to say is that you're free to customize the yaffs support/nand chip driver for your own chip to get rid of the shim layer translating smartmedia layout into generic, and that will speedup things. Hope that helps Vitaly
