It suppoers page program with built-in erase command... So DataFlash effectively may be considered as a block device. Then you may use any FS on it providing you have wrote proper driver? Why do you need JFFS2 then :-) ? JFFS2 orients to "classical" flashes. They have no "write page with built-in erase" operation. Didn't read the manual carefully, what do they refer by "Main memory array"? BTW, having 8*1056 write buffer is not perfect ides, better make it as small as possible, i.e., 1056 bytes. -- Best Regards, Artem B. Bityuckiy, St.-Petersburg, Russia.
