High-Assurance Firmware Update
Development of reliable firmware update solutions for professional embedded products.
Bootloader Architecture Design
Support across the full product lifecycle, from development, testing, and deployment to maintenance and end-of-life, with a focus on reliability and maintainability.
Firmware Verification
Image authentication, signature verification, and key management strategies tailored to embedded constraints.
Fail-Safe Firmware Updates
A/B update strategies, rollback mechanisms, and power-loss resilience to prevent device bricking.
Memory Layout & Boot Flow Design
Flash partitioning, linker integration, startup sequencing, and microcontroller-specific constraints.
Integration Into Existing Systems
Integration with RTOS or bare-metal applications, MAIT workflows, and update infrastructure.
Firmware Update Risk & Resilience Assessment
Firmware updates often fail in edge cases: power loss during flash writes, interrupted swaps, or undefined boot states. These failures can permanently brick devices in the field.
We provide an independent technical assessment of your firmware update mechanism to identify risks and verify that your system behaves safely under real-world failure scenarios.
The assessment focuses on:
- Update state machine determinism
- Power-loss and reset failure modes
- Flash atomicity and metadata integrity
- Recovery guarantees after interruption
