RTOS and middleware partner

Zephyr RTOS

IAR's ecosystem

Our partnership

Zephyr RTOS is rapidly becoming a leading open-source real-time operating system for resource-constrained embedded systems. Backed by the Linux Foundation and over 45 contributing organizations, Zephyr supports multiple architectures: Arm, RISC-V, and more and runs on 750+ boards from vendors like NXP, Renesas, ST, Infineon, and Nordic.

IAR is proud to be an official member of the Zephyr Project since February 11, 2025, reinforcing our commitment to open-source collaboration and scalable, production-ready embedded development.

Zephyr

Why Zephyr + IAR?

IAR offers full build support for Zephyr with our Arm toolchain (v9.70 and later), giving you the best of both worlds: the agility of open source and the reliability of enterprise-grade tools.

  • Optimized code generation and safety-certified compiler
  • RTOS-aware debugging via C-SPY Listwindows and VS Code integration
  • CMake and west build integration for smooth setup
  • Safety certification readiness with ISO 26262 and other standards
  • CI/CD and cross-team workflow support for modern development

IAR helps you scale Zephyr-based development through debugging, certification, and toolchain standardization, all backed by dedicated technical support and automated testing.
