Hi Avi, Set Up Your Development Environment.

Ensure your Yocto build environment is properly configured and that OP-TEE is included in your image. 

Install the required tools for developing Trusted Applications:
Toolchains: OP-TEE uses arm -none-eabi-gcc for building TAs.
Repositories: Clone the OP-TEE repositories, including optee_os, optee_client, and optee_examples from OP-TEE Github.
Create a new TA project directory under optee_examples or similar.
Write your trusted application code.
Create a new TA project directory under optee_examples or similar.

Build the TA using the OP-TEE build system:

Navigate to your Yocto build environment.
Integrate the TA into the Yocto recipe:
After building, you will have the .ta binary in the output folder.
Deploy the TA by copying it to the /lib/optee_armtz/ directory on your target board. Ensure that it matches the UUID defined in your application.
Test and Debug Your TA.

I hope the above instructions helped you, feel free to write & ask me any questions!

BR,
Ashutosh Nama.

Hello!

To create a Trusted Application (TA) for OP-TEE on your NXP 8MPLUS BB board, set up your development environment, create the TA directory structure, write the TA code with the necessary entry points, build the TA using the OP-TEE TA-devkit, and deploy the TA binary to your target device.
