Encryption on imx6 cpus

Dear NXP community,

 

since I am able to encrypt the uboot successfully, I can't boot the linux kernel image (uImage).

 

I noticed, l that the kernel stops initialisation when he wants to load the caam drivers.

 

When I use the [Unlock] command in my CSF file (with Engine = CAAM; Features = RNG) the kernel boots!

 

Without this command he stopps at said drivers.

 

I am using the code signing tool 2.3.2

 

So my question is, is this Unlock cammand   necessary?

If so, why...

 

Regards,
