Zephyr RTOS consulting that ships
Get a stable BSP, production-quality drivers, and deterministic testing with twister and west—so your Zephyr-based product ships on time with confidence.
Common Zephyr blockers we unblock
BSP & devicetree friction
Getting board support stable takes longer than expected. Devicetree changes break builds. Pinmux and clock configurations are fragile and undocumented.
Driver quality gaps
Drivers work in demo scenarios but fail in production. Driver APIs are inconsistent. No clear test strategy or ownership for peripheral drivers.
Flaky twister tests
CI with twister is unreliable—tests pass locally but fail in CI. Intermittent failures and timing-dependent tests erode trust in the pipeline.
Slow west/build feedback
Long build times, unclear build errors, and poor caching make development slow. West workspace setup is fragile and hard to reproduce across the team.
What you get in 30 days
Stable foundation
Reliable pipeline
In a recent engagement that meant 8+ production Zephyr drivers and 2 board bring-ups in 30 days—stable BSP, drivers from reference manual, and CI you can trust.
We focus on reducing fork and patch debt so upgrades don’t become a quarterly fire drill—drivers, devicetree, and build workflows stay aligned with upstream practices.
Typical Zephyr deliverables
Board support & devicetree
- Custom board definition with devicetree overlays
- Pinmux, clock tree, and power management configuration
- Board documentation and bring-up checklist
Production-quality drivers
- Peripheral drivers following Zephyr driver model
- Driver test suite (unit + integration with twister)
- Clear interfaces and usage examples for the team
CI/CD & testing
- Twister test configuration with deterministic tests
- CI pipeline (GitLab CI or GitHub Actions) with caching
- CI hardened for real constraints (runner disk, toolchain drift, and scripting pitfalls)
- Release automation and artifact management
Knowledge transfer
- Architecture decision records (ADRs) for key choices
- Onboarding docs for west workspace and build system
- Handoff session covering deliverables and next steps
How we engage
Zephyr bring-up rescue
Get to a stable baseline fast: reproducible BSP, working drivers, and clear documentation so your team can maintain it.
Driver delivery sprint
Production-quality peripheral drivers with test coverage and a clean driver model your team can extend without regressions.
CI/test hardening
Make twister tests deterministic and fast. Harden your CI pipeline so builds are reliable and feedback loops are tight.
Proven results on Zephyr projects
Real outcomes from engineering teams who shipped Zephyr-based products with our help.
“Martin helped us stabilize our Zephyr BSP and deliver 8+ production-quality drivers and 2 board bring-ups in 30 days. Our CI went from 60% flaky to 100% reliable. We shipped on time for the first time in 18 months.”
Engineering Manager
VP Engineering at IoT Hardware Startup
Project: Zephyr RTOS bring-up and driver development
“The devicetree refactoring and test hardening work was exactly what we needed. Clear documentation, clean commits, and a solid handoff. Our team can now maintain and extend the BSP without blockers.”
Tech Lead
Senior Firmware Engineer at Medical Devices
Project: Zephyr CI/CD hardening
“We were stuck on a legacy RTOS with no path forward. Martin helped us port to Zephyr, set up a stable build system, and train the team. We now ship firmware updates quarterly instead of yearly.”

Zephyr FAQ
Do you work with custom Zephyr forks or upstream-first?
Both. We can deliver on your existing fork and help you align with upstream practices so you can pull in updates without breaking your custom work.
What do you need to get started?
Access to your west workspace/repo, target hardware details (SoC, board schematics if available), and a short call to align on scope and priorities.
Can you help migrate from another RTOS to Zephyr?
Yes. We've helped teams port from FreeRTOS, ThreadX, and bare metal to Zephyr with minimal disruption to existing application code.
What if we're already using Zephyr but stuck on specific issues?
Perfect fit. Most engagements start with teams already on Zephyr who need help with BSP stability, driver quality, or CI reliability. We can jump in and unblock immediately.
