About HF·NODE
HF·NODE is an AI hardware debugging agent designed for embedded systems that provides zero-SDK firmware debugging and probe-level embedded debugging without integration. It enables remote SWD/JTAG debug-port access and monitors power rails, serial output, and GPIO states independently of the target device. The tool observes hardware signals such as rail current, supply voltage, and GPIO state, correlating them with firmware logs to detect discrepancies like silent hangs, unexpected current draws, or brief power sags. When a fault occurs, HF·NODE captures the 90 seconds of pre-event logs and hardware traces, generates a root-cause hypothesis, and can recover the device by reflashing it via the debug port even if the target is unresponsive. It supports automated regression testing, overnight bug hunts, and power-profile checks on real silicon, reducing the need for manual oversight during firmware development and deployment. The system operates across multiple MCU families including STM32, ESP32, ESP8266, AVR/Arduino, EFR32, and nRF52, as well as generic serial devices.

Frequently asked questions about HF·NODE
What is HF·NODE and what does it do?
HF·NODE is an AI hardware debugging agent for embedded systems that provides zero-SDK firmware debugging and probe-level embedded debugging without integration. It enables remote SWD/JTAG debug-port access and monitors power rails, serial output, and GPIO states independently of the target device.
Who is HF·NODE designed for?
HF·NODE is designed for developers and teams working with embedded systems, particularly those using AI-driven firmware development workflows. It suits engineers who need automated debugging, regression testing, and overnight monitoring without manual oversight.
How does HF·NODE help with debugging embedded systems?
HF·NODE gives AI a second point of view by observing hardware signals such as rail current, supply voltage, and GPIO state, correlating them with firmware logs. When a fault occurs, it captures pre-event logs and hardware traces, generates a root-cause hypothesis, and can recover the device by reflashing it via the debug port.
Does HF·NODE require any code changes or SDK integration?
No, HF·NODE operates without requiring any SDK integration or code changes on the target device. It works independently by monitoring hardware signals and debug ports.
What hardware and MCU families does HF·NODE support?
HF·NODE supports multiple MCU families including STM32, ESP32, ESP8266, AVR/Arduino, EFR32, and nRF52, as well as generic serial devices.
Can HF·NODE recover an unresponsive device?
Yes, HF·NODE can recover an unresponsive device by reflashing it via the debug port, even if the target is completely unresponsive. This allows for automated recovery in build-flash-test loops.
