There is now some MTD API documentation available. It’s a little out of date – the API has been evolving over the last few months as we encounter strange pieces of hardware that we hadn’t anticipated, and occasionally when I’d just overlooked something blatantly obvious. Volunteers to update the docs are welcome.
13th Feb 2001: A mtd-jffs-HOWTO is now also available under CVS. Not all topics are covered yet, but it’s a start.
5th May 2002: A NAND Flash document is now available. It covers some technical topics about NAND and filesystems and contains a FAQ.
1st June 2004: A NAND Flash API document is now available.
15th Feb 2005: A MTD FAQ is now available.
