Your question is Choosing RTOS vs Bare Metal. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Which one is better to use, FreeRTOS or bare metal programming, and why?
Explain how you would choose between them for an embedded system. Compare determinism, timing behavior, memory and CPU overhead, interrupt handling, reliability, security boundaries, debugging, testing, and long-term maintainability. State when each approach is appropriate and identify the failure modes you would verify before deployment.
