Yes you can very well use jffs2 for nand . it works fine . -----Original Message----- From: linux-mtd-bounces@lists.infradead.org [mailto:linux-mtd-bounces@lists.infradead.org] On Behalf Of Darshak Sent: Monday, November 20, 2006 10:10 AM To: dedekind@infradead.org Cc: linux-mtd@lists.infradead.org Subject: Re: starter! is JFFS2 is worth using for NAND flash ? or it supports only NOR? I come to know that JFFS2 has some problems at mounting [ takes longer time ] and occupies more RAM? How much time does it take to mount 512 and 1 GB flash? How much RAM does it require?
