Hi, I am using mini2440 board. I am trying to create jffs2 rootfs image of my own with the help of Karim Yaghmour book. In that it is mentioned as while creating jffs2 image we will have problems unless if we specify the erase block size option in the mkfs.jffs2 command same as device's erase block size. What is the size and where and how can I get the erase block size data? Please reply!
