IMX7D HAB required for OPTEE?

marcer1 — Mon, 14 Oct 2024 12:22:04 GMT

Hello everyone,

I would like to install OPTEE on an IMX7D or an IMX8X. Do I really have to enable HAB to use OPTEE? My Project is student preliminary work, so it would be okay if the system is not completly secure, as long as i document it.
But I don't know if it's a prerequisite of optee to have HAB and SecureBoot running to use it.

Thank you so much,

marcer1

Hello,

With yocto

Add to your local.conf:

IMAGE_INSTALL_append = " optee-examples"

In future how to add my own trusted applications to Yocto.

Create a recipe based on recipes-security/optee/optee-examples.bb and add it to the image as stated above.

Regards

Adding examples was not the question. I asked if I need to enable High assurance boot on nxp processors to use the OPTEE Feature.
