Firmware on Zephyr RTOS
PRM.DEV develops firmware on Zephyr — an open RTOS from the Linux Foundation, vendor-agnostic and well suited for connected sensors, smart devices, trackers, modems, and wireless gateways.
Zephyr advantages
  • Fast start

    West tool, rich driver base, easy board bring-up, reuse of Linux drivers.
  • Easy scaling

    Overlays keep a single base build with variants — no code duplication.
  • MCU freedom

    One codebase across multiple vendors and MCU familie

Where it fits

FreeRTOS vs Zephyr vs Linux
  • FreeRTOS
    • Use: MCU apps
    • Features: RT, sync
    • Resources: constrained
    • Examples: simple sensors, IoT
  • Zephyr
    • Use: MCU & multi-core SoC
    • Features: drivers, networking, FS
    • Resources: scalable, SMP/AMP
    • Examples: trackers, gateways, HMI
  • Linux
    • Use: high-performance systems
    • Features: rich services, drivers
    • Resources: high RAM/CPU
    • Examples: panels, GUI gateways
Zephyr capabilities
  • Configurable

    Kconfig (from typical to fully custom), Device Tree for boards/architectures.
  • Reliable

    Preemptive tickless kernel, advanced memory mgmt, SMP/AMP, 32/64-bit.
  • Secure

    Static analysis, fuzz/pen testing, reviews, threat modeling; PSA Certified L1.
  • Modular

    From ~8 KB to MB-scale systems; custom toolchains; West-based mono-repo.
  • Adaptable

    Apache 2.0, easy integration and customization.
  • Connected

    BLE, Wi-Fi, 802.15.4, Ethernet, USB, CAN, 6LoWPAN, CoAP, Thread, etc.
