Embedded Systems & Firmware

Chandigarh.IT provides specialized embedded systems engineering for safety-critical and performance-sensitive applications. Our firmware developers, device driver engineers, and RTOS specialists work across automotive, medical devices, aerospace, industrial automation, and consumer electronics. We combine deep hardware understanding with modern software practices to deliver reliable, certifiable, and maintainable embedded solutions — including EU Cyber Resilience Act (CRA) compliance readiness for connected products.

Firmware Development

We develop custom firmware for microcontrollers and embedded processors, from bare-metal implementations for resource-constrained devices to RTOS-based architectures using FreeRTOS, VxWorks, and Zephyr. Our firmware is written for reliability, deterministic timing, and long-term maintainability.

We design and implement secure bootloaders with chain-of-trust verification, encrypted firmware updates, and over-the-air (OTA) update mechanisms. Our bootloaders support rollback protection, A/B partitioning, and secure key management for field-deployed devices.

We develop complete board support packages including Linux kernel customization, hardware abstraction layers, peripheral initialization, and boot sequence optimization. Our BSP work covers custom SoC platforms, evaluation boards, and production hardware bring-up.

We implement wireless and wired connectivity stacks for IoT devices including WiFi, Bluetooth Low Energy, LoRa, Zigbee, and industrial protocols like CAN bus. We handle protocol stack integration, power optimization for battery-operated devices, and secure communication with cloud platforms.

We modernize legacy embedded systems by migrating firmware to current processors and RTOS platforms, refactoring monolithic codebases into modular architectures, adding connectivity to isolated devices, and updating systems to meet current safety and security standards.

We develop power management firmware for battery-operated and energy-constrained devices, implementing sleep modes, dynamic voltage scaling, peripheral power gating, and intelligent wake-up strategies to maximize device battery life and operational efficiency.

Device Driver Development

We develop production-quality Linux kernel device drivers for USB, PCIe, SPI, I2C, UART, GPIO, and custom peripherals. Our drivers follow upstream Linux coding standards and can be submitted for mainline kernel inclusion when appropriate.

We develop Windows device drivers using WDM and WDF frameworks, including kernel-mode and user-mode drivers. We support the full WHQL certification process to ensure your hardware is fully compatible and signed for Windows deployment.

We write device drivers for real-time operating systems including FreeRTOS, VxWorks, QNX, and ThreadX. Our RTOS drivers are designed for deterministic behavior, minimal interrupt latency, and compliance with safety-critical coding standards.

Testing & Compliance

We provide hardware-in-the-loop (HIL) testing services to validate embedded software against real hardware behavior in controlled environments. Our code adheres to MISRA-C guidelines for safety-critical applications, with static analysis and comprehensive test coverage.

We develop firmware and documentation that meets the requirements of safety-critical standards: ISO 26262 for automotive, IEC 62304 for medical devices, DO-178C for aerospace software, and IEC 61508 for industrial safety systems. Our processes are designed to support your certification efforts from the ground up.

We help manufacturers prepare for the EU Cyber Resilience Act by implementing secure development practices, vulnerability management processes, and software bill of materials (SBOM) generation for connected products entering the European market.

Frequently Asked Questions

We work with all major real-time operating systems including FreeRTOS, VxWorks, Zephyr, QNX, and ThreadX (now Azure RTOS). Our team selects the optimal RTOS based on your application requirements, real-time constraints, safety certification needs, and hardware platform.

Yes. We regularly migrate firmware from end-of-life processors to current platforms, port code between RTOS environments, and refactor legacy monolithic firmware into modern modular architectures. We preserve critical functionality while improving maintainability, security, and performance.

We develop firmware and documentation aligned with ISO 26262 (automotive functional safety), IEC 62304 (medical device software), DO-178C (airborne software), and IEC 61508 (industrial functional safety). Our development processes, coding standards (MISRA-C), and testing practices are designed to support your certification path.

Yes. We offer HIL testing services where embedded software is validated against real hardware behavior in a controlled test environment. This is essential for safety-critical applications where software must be verified under simulated real-world conditions before deployment. We also provide automated regression testing frameworks for ongoing firmware validation.
