How can I build OP-TEE with Android on a HiKey board?
First, I found "https://github.com/jforissier/hikey_optee," but it's outdated and gave me the link "https://github.com/linaro-swg/optee_android_manifest."
It said that
This 'widevine' branch adds support for a repo that is only available to certain parties under NDA. If you have access to this repo, you should make sure that you can access it before running the 'repo sync', otherwise repo tends to hang. If you do not have access to this repo, you should use the 'master' branch.
I tried to use 'master' branch, but it looks the same as the result of 'widevine' branch.
How can I build them? Can I manually setup each OP-TEE and AOSP?
