Hi NXP Team,

 

Hardware: IMX8QM Custom Platform

Software: L5.10.52

 

I able to sign bootloader and kernel using Code Signing Tool. But, I unable to find out the steps to sign the Root File System.

Will you please provide the steps or document for sign the root file system like bootloader and kernel.

Hello,

  We recommend using dm-crypt approach, described in app note AN12714.
