i.MX8M OPTEE Enablement

Question asked by Shengye Wan on Dec 17, 2018

Hi experts,


I just got my i.MX 8M Evaluation Kit and I want to enable the OPTEE OS on the board.

I found one tutorial about Yocto Project provides such support so I'm trying to build the system according to this guidance.

I build the fsl-image-qt5-validation-imx image with Wayland configuration and set the OPTEE option as enabled.

The output images can be booted with SD card on my imx8mevk device.


So far I can connect with the normal world Linux kernel via serial communication.

However, I do not find any instruction about connecting to the OPTEE OS, such as reading the system output or inputting for the system?


Any suggestion or related document is welcomed!


Thank you in advance.
