Here is the command I used to generate the mkfs.jffs2.img file,
mkfs.jff2 -s 4096 -r src_directory -e 0x20000 -o rootjffs.img
after that I was using the nandwrite utility using following command and the results,
sam9-l9260:/# nandwrite -a /dev/mtd1 rootme.img
Input file is not page aligned
Data was only partially written due to error
: Success
Anybody have idea to resolve this?
