HardFaultHandler

HF·NODE provides external debug capabilities for embedded boards, allowing a development agent to operate unattended. Key functionalities include: • Differentiating between wedged and dead board states • Detecting power conflicts invisible to firmware • Reflashing bricked targets via debug port • Monitoring GPIO, ADC, and power rails • Tracking device life state and CPU/register conditions This robust tool gives an external perspective, observing and diagnosing board behavior even when the firmware goes silent. It captures pre-event buffers with logs and traces, enabling precise root-cause analysis and recovery actions, either with approval or autonomously. HF·NODE works without an SDK or code changes, integrating seamlessly into existing workflows. Designed for engineering teams and developers working with embedded systems like STM32, ESP32, AVR/Arduino, EFR32, and nRF52, HF·NODE allows for continuous development and debugging cycles. It empowers an agent to observe, diagnose, recover, and retry firmware flashing and testing overnight, minimizing downtime and accelerating the development process. It's ideal for scenarios where internal device logs are insufficient or inaccessible due to device failure.
