[Re]Configuring & building OP-TEE + ATF The initial step would be to embed OP-TEE OS into our firmware boot package and re-configure (and recompile) ARM Trusted Firmware-A to load it. But first, we need to understand the memory organization of our board. This is required since BL31 (TF-A) has to configure the TZASC peripheral to reserve a trusted region inside the main memory (DRAM) for use by our Secure OS & TAs. text/html 2025-08-08T14:28:42+03:00 http://ocw.cs.pub.ro/courses/ass/labs-2025/05/tasks/02?rev=1754652522&do=diff 02. Writing Trusted Applications In the second part of our lab, it's time to run some Trusted Applications (TAs)! We will use the official optee_examples as starting point. Two questions arise: how can one compile a TA? + how to test it on our board?
