Build Instructions

1. Create your OP-TEE workspace

    mkdir -p <optee-workspace>
    cd <optee-workspace>
   

2. Setup the OP-TEE software stack in your newly created <optee-workspace> by following: https://github.com/OP-TEE/optee_os#5-repo-manifests

3. Clone this repository into <optee-workspace>

    git clone https://github.com/jenswi-linaro/lcu14_optee_hello_world.git optee_hello_world
