jffs????

kw2000

我是用32M doc,想使用jffs2，我运行了
flash_eraseall /dev/mtd0 ;
mkfs.jffs2 -r xxx -o xxx -e=0x4000 -b
dd if=xxx of=/dev/mtd0 bs=16k
mount -t jffs2 /dev/mtdblock0 /mnt 出错
查看dmesg如下：
[root@localhost root]# dmesg
n_eraseblock(): Magic bitmask 0x1985 not found at 0x00648008: 0x60f0 instead

Further such events for this erase block will not be printed

....
类似上面的
.....
Cowardly refusing to erase blocks on filesystem with no valid JFFS2 nodes
