Unoficial helper tools for building Trusted Applications for Android using OP TEE. This script should not be used as a standalone tool. It requres the OP TEE toolchain and OP TEE OS stored in the script directory.
Assuming that the script is checked out in the optee/ folder of your AOSP root
$ source build/envsetup.sh
$ lunch hikey-userdebug
$ $ ./optee/build_ta.sh hikey optee/android_optee_examples.cfg
