Oki, then I at least know where to look. It would have been a nice feature to add support for choosing endianess when loading the module. I would not recommend customers or less experienced Linux people to recompile one of their kernel modules to support big endian JFFS2 images. > > mount -t jffs2 /dev/mtdblock0 /some/mount/point > > FYI, mtdblock is not needed and is ancient and confusing way to mount > jffs2. > > http://www.linux-mtd.infradead.org/faq/jffs2.html#L_mtdblock Oh, thanks, and as Håvard stated it is also supported in the latest busybox. -- Mvh Hans-Christian Egtvedt
