Custom Firmware Development Services

  • Evon is a custom firmware development company focused on building reliable, real-time embedded applications for edge devices. We work with businesses across logistics, security, industrial control, automotive, and defence.
  • Our team provides expert firmware development services and RTOS-based logic that runs directly on the device. We design systems that respond instantly and keep functioning even when networks go down or inputs flood in.

Firmware for Time-Critical Applications

As embedded systems grow more complex, their reliance on cloud infrastructure can cause critical delays. Devices in logistics, security, or control systems need to make decisions locally and quickly.

Evon delivers firmware development services that enable edge-side responsiveness, with or without an RTOS, optimised for your application and platform.

Firmware Across Sectors

We build real-time firmware for sectors that operate under pressure, where disruption isn't an option

FAQ

Chip vendors provide basic SDKs. We build production-grade firmware with tighter timing control, hardware validation layers, fault tolerance, and field deployment readiness.

Yes. We evaluate your use case, if deterministic timing or ultra-low power is critical, bare metal may be more suitable than an RTOS.

Yes. Our edge-first builds are designed to run logic offline; sensors, thresholds, and device actions all happen locally. Cloud sync is optional, not mandatory.

We design modular firmware to support OTA from the start. This includes update integrity checks, rollback protection, and minimal memory overhead for resource-constrained devices.

We offer field testing tools, debug builds, and remote diagnostics hooks. Post-launch, we remain involved for bug fixes, updates, and hardening.

Yes. We've delivered modules aligned with AUTOSAR and ASIL requirements. Safety, timing determinism, and fail-safe states are core to such builds.

RTOS provides the underlying scheduling and task management framework, but most applications still require firmware tailored to their use case. This includes handling interrupts, managing peripheral devices, controlling power usage, and implementing application logic. If your existing setup doesn’t fully meet these needs, custom firmware development can make your system more efficient and reliable. Let’s discuss your current setup and find out what’s really required.
