Hello 穆 昆空,

You could use OPTEE provided in the latest LSDK release from Layerscape SDK|NXP , QorIQ SDK 2.0 doesn't include this technology, please refer to section "6.2 Trusted Execution (OP-TEE)" in the document https://www.nxp.com/docs/en/supporting-information/LSDK-KC-REV18.03.pdf.

OP-TEE binary is part of ppa.itb image as loadables node in ppa.itb image, U-Boot parses the ppa.itb image and check if any loadables node is present in ppa.itb image. If loadables is present, then U-Boot loads the OP-TEE OS binary tee.bin


Have a great day,
TIC
