Zephyr Engineering

Turn Zephyr into a competitive advantage. RISCstar engineers help embedded product teams deliver connected, secure, and high-performance devices on Arm and RISC-V — on time and built to last.

Complexity in Connected, Embedded Real-time Systems

Delivering connected devices on time — while maintaining safety, security, and performance — is one of the hardest challenges in embedded engineering. Product teams face challenges such as:

Integrating new silicon and custom board designs quickly and reliably
Meeting strict real-time and power constraints across diverse hardware
Ensuring product and data security across the full device lifecycle
Supporting wireless connectivity standards
Controlling long-term maintenance costs and technical debt

Without the right expertise, integration delays and software instability can slow time-to-market and erode product margins. RISCstar provides the Zephyr engineering depth to overcome these challenges and deploy with confidence.

RISCstar's Approach to Zephyr Engineering

RISCstar engages from concept through deployment to ensure your product is ready for market success:

We bring up new silicon quickly — including clocks, power domains, and memory initialization — and deliver production-quality BSPs for your custom hardware designs.

We deliver high-performance driver support for sensors, connectivity modules, displays, and peripherals, aligned with Zephyr’s driver model and APIs.

We implement end-to-end wireless stacks including BLE, Wi-Fi, 802.15.4, Thread, and Matter — fully integrated and validated on your target hardware.

We analyze, profile, and tune your system to meet strict timing and power budgets, ensuring reliable real-time behavior across your full range of operating conditions.

We implement secure boot using MCUboot, build firmware-update pipelines, and deliver lifecycle management that keeps your devices secure in the field.

We align your product with Zephyr mainline, contribute patches upstream, and automate CI workflows — reducing technical debt and long-term maintenance overhead.

Why RISCstar?

Delivering a production-grade Zephyr product requires expertise that spans silicon, RTOS internals, connectivity, and security — and the discipline to make it sustainable over a product’s full lifetime. Our engineers bring:

Deep Zephyr and open-source expertise with real upstream contributor experience
Hardware-aware engineering from silicon bring-up to cloud interfaces
Linux and RTOS pedigree that enables advanced debugging and optimization
A focus on sustainability — lower cost of ownership across your product lifetime
A track record of delivering complex connected devices on time and within budget
