Hi
Trying to implement dm-verity for verifying/Authenticating my readonly rootfile system.
Host :
Successfully created hashtree and roothash for my ro rootfile system and verified it with verify command.
Target:(imx8m mini kernel)
Created a mapper /dev/mapper/vroot for the block device which has my readonly rootfile system with the help of hashtree and roothash.
when i try to mount it i'm getting below error.
sh-4.4# mount -o ro /dev/mapper/vroot /mnt/
