i.MX 8M mini secure boot with yocto

Dear NXP community,

I am trying to perform secure boot operation with yocto project on i.MX 8M Mini hardware. Following are the software details.

Software:

NXP github: imx-manifest
branch: langdale
release-manifest: imx-6.1.1-1.0.0.xml

Documents referred:

I am able to successfully build the yocto project without secure boot but I have few questions regarding the process of achieving secure boot using yocto project.

Does NXP provide a layer (/recipes) to enable secure boot with Yocto?
Or, do we need to configure our own recipe manually?
If yes, is there a guide or reference document/templates available for the same?

Regards,

Aditi Prakash

Hi @aditi1prakash

As I know, we've not had such support with Yocto so far.

Best regards

Harvey

Thanks @Harvey021.

I had a couple of follow-up questions:

Is there a recommended third-party layer that can sort of act as plug-and-play (or that can be integrated with minimal efforts) with NXP yocto project? Because many that I referred to (variscite, digi-embedded..) offer their own hardware based on i.MX for their software.
What would be the approximate effort to write these recipes on my own? (with basic knowledge of yocto project)
