hi ,
i'm using the bf527-ezkit
i want to make my changes on borad saved even after i reboot the system
my steps are as follows:
"make" the dist to get uImage,rootfs.jffs2
download uImage to the board and bootm
then
root:/> ls
bin home proc sbin usr
dev init root sys var
etc mnt rootfs.jffs2 tmp
root:/> eraseall /dev/mtd4
Erased 1792 Kibyte @ 0 -- 100% complete.
root:/> cp rootfs.jffs2 /dev/mtd4
root:/> mount -t jffs2 /dev/mtdblock4 /mnt
JFFS2 notice: (158) jffs2_build_xattr_subsystem: complete building xattr subsyst
em, 0 of xdatum (0 unchecked, 0 orphan) and 0 of xref (0 dead, 0 orphan) found.
root:/>ls /mnt
dev etc home mnt proc root sbin sys tmp usr var
root:/>
after that i reboot the system .
but the dir /mnt is still clean as before .
did i miss something or i didn't do the right steps?

jacqueline,
root:/> cp rootfs.jffs2 /dev/mtd4.
This is not correct. Use "nandwrite" to write a jffs image to nand flash.

did you remember to run `mount` again after rebooting ?
