I got latest MTD source code(2001-07-11 version)
and set Kernel options.

when the kernel booted, I found all correct messages from kernel. but, when I tyepd MAKEDEV, and then

mkfs.jffs -d /home/jffs -o /tmp/jffs.image
and

cp /tmp/jffs.image /dev/mtd0
the result message is

cp: /dev/mtd0 Read-only file system. <----Here.

so, I can't proceed next step!!

Could anyone explain this problem??
Any comments will help me.. thanks.

what filesystem do you use for root filesystem? if you use romfs, then mount /dev as ramfs and make node.

btw, if you want to copy to a raw partition (as you did above), you'll have to erase that partition first.

Or use the mtdblock device instead, which does erase it for you.
