Hi, > Is it mandatory to make a 'blank' JFFS2 filesystem image even for a blank > mtd device? jffs2 will refuse to mount unless at least one jffs2 was found on the device. Thats the reason why you can't mount an empty device. Just use eraseall -j <mtddevice> It will create a dummy inode so you can mount the device. Regards, Florian
