-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Seems to me you'd want a kernel that could boot off raw flash and run in RAM off a small RAM disk. Said kernel would have a low level driver that makes plain old flash chips look (and behave) like a disk. It would support wear-levelling, and (with data sheet in hand) could be statically configured to match the flash it's targetted to run on. Things like base address, device size, sector size, and all the timing stuff you need to worry about with flash. Then you could throw FFS on top of that. I understand Jim's preference for CF in that it handles all that stuff (including the wear-leveling) automatically, and then there's the convenience factor of having the media 'removable'. But you can reduce footprint and cost a lot if you could run off plain old flash or something like an M-systems doc device. I'm thinking there's a good chunk of the embedded market that has that requirement.
