Hi,
I am running MTD on customized imx6ull evk board, the root is a UBIFS
volume, installed from s ubinize image.
If I boot from a ramdisk to Linux, I could run ubiattach -p /dev/mtd2
and mount -t ubifs -r -v ubi0:rootfs-volume /mnt in ramdisk Linux, but
it failed in NAND kernel boot, looks like that the kernel was not able
to attach the mtd device or not able to mount to the rootfs-volume, do
I need to pass more parameters to kernel? Or what could I be missing
in the u-boot bootargs setup?
=> setenv bootargs "console=ttymxc0,115200 earlycon
mtdparts=gpmi-nand:1m(boot),1m(ubootenv),-(storage)
root=storage:rootfs-volume ro ubi.mtd=2,2048 noinitrd rootfstype=ubifs
mem=256M rootwait=1"

Hi Richard,
On 2/15/20, Richard Weinberger <richard.weinberger@gmail.com> wrote:
> There is no mtd2.
Sorry, that was fixed, please see an updated log that the mtd2 was
actually attached "ubi0: attaching mtd2", I am wondering if I edited
the /etc/fstab wrongly to cause the sytax issue and to fail the root
mount? Here is the /etc/fstab:
ubi0:rootfs-volume / ubifs defaults,relatime,ro,ubi=0,vol=2 0 0
ubi0:data-volume /data ubifs
defaults,noatime,rw,mode=0755,ubi=0,vol=3 0 0
#/dev/root / auto defaults 1 1
proc /proc proc defaults 0 0
devpts /dev/pts devpts mode=0620,gid=5 0 0
tmpfs /run tmpfs
mode=0755,nodev,nosuid,strictatime 0 0
tmpfs /var/volatile tmpfs defaults 0 0
Again attached the bootargs:
=> setenv bootargs "console=ttymxc0,115200 earlycon
mtdparts=gpmi-nand:1m(boot),1m(ubootenv),-(storage) root=${root}
ubi.mtd=2,2048 noinitrd rootfstype=ubifs mem=256M rootwait=5"
=> run bootcmd;

Hi Richard,
In u-boot, mtdparts=gpmi-nand:1m(boot),1m(ubootenv),-(storage), looks
like kernel did not know the name "storage", changed
root=storage:rootfs-volume to root=ubi0:rootfs-volume, it went to
further to start UBIFS, but still failed Unable to mount root fs on
unknown-block(0,0):

Hello,
Has that issues been resolved long time ago or is that link still
relavent to today's kernel mount to UBIFS volume
https://lore.kernel.org/patchwork/patch/791663/?
"There currently appears to be no way for userspace to find out the
underlying volume number for a mounted ubifs file system, since ubifs
uses anonymous block devices. The volume name is present in
/proc/mounts but UBI volumes can be renamed after the volume has been
mounted."
Do I need a patch to fix it in kernel 4.19?
Does it has to use rw,relatime in fstab? My rootfs-volume is RO, can
the RO rootfs-volume work on kernel mounting?
Thank you, appreiate your kind advice.
Kind regards,
- jh
