TEE Integration, Examples, and Documentation

[TEE Integration, Examples, and Documentation]

I tried downloading https://gitee.com/rockchip/rk_tee_user to system/ and compiling it.
Client applications are built, but TA applications are not built.
It is probably because GCC is configured for a different board.
It would really help if I could get a guide to compile TA for rk3399, Asus Tinker Board 2.

Hello,

I want to develop TZ applications within Tinkerboard 2. I am using AOSP Android v10 open source.
How do I integrate TEE? I raised this question here: https://github.com/TinkerBoard2-Android/manifest/issues/2
However, the documentations provided seems to be in Chinese. Is there English docs somewhere?
Furthermore, I do not have system/rk_tee*  or rk_tools in my AOSP source after a sync and build. What am I missing here?

Thank you very much.
