I currently use Toradex's verdin-imx8mp development board, but Toradex does not officially support optee. I use yocto to integrate optee os, optee client, and optee test into the root file system.After booting, I found that the optee os could not be successfully loaded. I don't know what the reason is. How can I correctly implement the support for optee on the verdin-imx8mp development board? What do I need to change?
