     I want to load rootfs readonly on my imx6q, the rootfs is debian_armhf.

     In uboot I set the args as:


     setenv bootargs_mmc 'setenv bootargs ${bootargs} root=/dev/mmcblk1p1 rootwait ro video=mxcfb0:dev=lcd,1440x900,if=RGB24'


     and I do get verbose in bootup:


     EXT3-fs (mmcblk1p1): mounted filesystem with writeback data mode

     VFS: Mounted root (ext3 filesystem) readonly on device 179:25.


     But in the system I still get rw in mtab and the rootfs is still writable.


     How can I solve it?
