RTOS firmware development with FreeRTOS and Zephyr
RTOS firmware development and review when tasks, timing, memory and communication must be controlled. Support covers FreeRTOS, Zephyr, ThreadX and real-time architecture for embedded products.
Real-time means design, not just using an RTOS
An RTOS solves some problems and exposes others: priorities, mutexes, queues, stack, heap, interrupts, deadlocks and jitter must be designed together.
- Task architecture, state machines, queues, events and synchronization.
- Porting and development on FreeRTOS, Zephyr, ThreadX or vendor solutions.
- Timing, stack, heap, priority, race condition and deadlock analysis.
- Drivers, middleware, logging and tests on real targets.
What it includes
Evaluate FreeRTOS, Zephyr, ThreadX or bare-metal based on real constraints.
Priorities, queues, events and synchronization with measurable behavior.
Trace, stack usage, race conditions, watchdogs and sporadic bug reproduction.
Modular structure, repeatable builds, documentation and tests.
Working method
- Review goals, constraints, existing code, systems and business priorities.
- Define risks, architecture, measurable checkpoints and an execution plan.
- Implement or debug in verifiable steps on real data, code or hardware.
- Deliver code, documentation and decisions the team can maintain and evolve.

Frequently asked questions
Is FreeRTOS or Zephyr better?
It depends on hardware, team skills, certification, networking, drivers, memory and expected product lifetime.
Can you stabilize an existing RTOS project?
Yes. Work usually starts from trace, stack, heap, priorities and points where behavior becomes non-deterministic.
