求问，华硕官方固件怎么开启jffs

只为***

以下是mount后命令
admin@(none):/# mount
rootfs on / type rootfs (rw)
/dev/root on / type squashfs (ro,relatime)
devtmpfs on /dev type devtmpfs (rw,relatime,size=62744k,nr_inodes=15686,mode=755)
proc on /proc type proc (rw,relatime)
tmpfs on /tmp type tmpfs (rw,relatime)
sysfs on /sys type sysfs (rw,relatime)
devpts on /dev/pts type devpts (rw,relatime,mode=600)
/dev/mtdblock3 on /jffs type jffs2 (rw,noatime)
usbfs on /proc/bus/usb type usbfs (rw,relatime)
