Yocto - verify rootfs

[tomasklein]

Hi,

I would like to ask, how could i verify an integrity of rootfs. I would like to create a hash or signature of rootfs and store it in for example kernel image. Uboot and zImage are already signed with HAB tool. Maybe my idea is wrong, but how could I verify integrity of my rootfs ?

PS: As build tool I am using Yocto.

Thank you, for any advice :smileyhappy:

Hello,

   NXP does not provide recommended (HAB) solutions for rootfs, nevertheless, hope, the following 

considerations may be interesting.

Have a great day,
