error when coping jffs2 file system to mtd0

Hi all,

I have DOC 2000 and I can "mount -t msdos /dev/nftla1 /mnt".

I prepare a root.jffs2 using mkfs.jffs2 -d /dir -o root.jffs2

However, when I want to copy my root.jffs2 to /dev/mtd0, I get the following errors:
Dec 9 10:48:09 webprint syslog.info klogd: MTD_open
Dec 9 10:48:09 webprint syslog.info klogd: MTD_ioctl
Dec 9 10:48:09 webprint syslog.info klogd: Invalid ioctl 5401 (MEMGETINFO = 80204d01)

Dec 9 10:48:09 webprint syslog.info klogd: MTD_close

I have tried serval times, and get the same errors. What did I miss?

Thanks,
Martin
