Hi Kristian, I agree that talking about JFFS2 on CF is not a right things. Search high and low on MTD list and Yaffs and not found anything related to CF card :-(( I see that recent kernel have better JFFS2 support, mostly in mounting and checking JFFS2 partition. But sure that we cannot cut down the Flash->CF->Block dev emul-> JFFS2 path.
I will try the "sync" option as you suggest. Since I really need the r/w partition, so if this not work reliably, the last option maybe a ramdisk and some scripts to atomically synchronize the changes.
