I used the MTD code to accomplish the same thing. I have a compressed ext2 filesystem image sitting in FLASH and pass the MTD slram driver the beginning and ending address and it exposes the FLASH as /dev/mtd0. To make sure we're on the same page, I'm talking about a read-only filesystem. Check out http://www.linux-mtd.infradead.org/ to get started with the MTD layer. I'm under the impression that MTD has gone into the 2.4 kernel so it should become "the" way of doing this. Scott Anderson scott_anderson at mvista.com MontaVista Software Inc.
