Production-grade firmware with secure boot, cryptographic signing, OTA updates, and comprehensive error handling.

Secure boot chain with cryptographic signature verification
Over-the-air (OTA) update infrastructure with rollback protection
CRC-32 and SHA-256 integrity checking for flash storage
Watchdog timer management with multi-stage fault recovery
Flash memory wear leveling and bad block management
Fail-safe dual-bank firmware architecture with recovery mode
Firmware is often the most vulnerable layer — we prioritize security from day one with encrypted bootloaders and secure key storage.
OTA, Secure Boot, CRC — delivering measurable impact through deep technical expertise.
From discrete consulting engagements to full turnkey delivery, we adapt to your program's specific needs and timeline.
ChipTalk's firmware engineering practice prioritizes security, reliability, and long-term maintainability. Our firmware team has shipped products with encrypted OTA update infrastructure, dual-bank failover architectures, and MISRA C-compliant codebases across medical, automotive, and industrial domains.
Architected a secure firmware platform for an EV charger line, including OTA delta updates, ISO 15118 PLC communication stack, and secure boot with hardware-backed key storage.
Developed a fault-tolerant dual-bank bootloader for a smart electricity meter, enabling remote firmware updates with automatic rollback on CRC mismatch—deployed across 2M+ units.
Our firmware is designed for 10-year field life. We implement write-leveling for flash endurance, CRC-protected configuration blocks, and multi-stage watchdog recovery—so your product stays reliable long after the last update.
