You should use the bootargs as "ubi.mtd=6 root=ubi0:p2020ds-rootfs rw rootfstype=ubifs console=ttyS0,115200" according to the following information on your target board.

# ubidetach /dev/ubi_ctrl -m 6

# ubiformat /dev/mtd6 -f ./ubi.img

# ubiattach /dev/ubi_ctrl -m 6

# mount -t ubifs ubi0_0 /mnt

hi yipingwang

the command flash_eraseall /dev/mtd5 operation success, but the ubiformat /dev/mtd5 -y fail and aome excptin ocuuue pls help me to slove this problem thank u.

yipingwang · ‎09-08-2020

Please check whether you configured Linux Kernel as the following.

Device Drivers --->

<*> Memory Technology Device (MTD) support --->

< > Parallel port support --->

<*> Enable UBI - Unsorted block images --->

<*> NAND Device Support --->

Please try whether you could use ubiformat to format other partition.

xiaonanpeng · ‎08-28-2020

hi

I follow this operation . can u tell me the MTDIDS_DEFAULT and MTDPARTS_DEFAULT the value string.

as example.

xiaonanpeng · ‎08-13-2020

hi

i donot know the reason of the bellow error in the uboot . can I use ubifsmount command in the uboot?

ubifsmount p2020ds-rootfs
UBIFS error (pid 0): ubifs_get_sb: cannot open "p2020ds-rootfs", error -22
UBIFS error (pid 0): ubifs_mount: Error reading superblock on volume 'p2020ds-rootfs' errno=-22!

ubifsmount - mount UBIFS volume

Usage:
ubifsmount <volume-name>
- mount 'volume-name' volume

yipingwang · ‎08-14-2020

Please refer to the above procedure, please format the rootfs into the MTD block with command ubiformat in Linux.

xiaonanpeng · ‎08-16-2020

hi Yiping Wang

when ubiformat: formatting eraseblock 2 -- 0 % complete it is still 0 % complete. It can not complete. what's the problem ? thank U
