Coding agents have got good at generating embedded code. What they can't do is check whether any of it works on the actual chip no register state, no rail current, no idea if the last flash even booted. So a human ends up being the sensor in the loop.
Curious how others are handling this. Are you using agents for firmware at all? And if so, what's your verification step hardware in the loop, manual bench testing, or just reading it carefully and hoping?
HF·NODE puts AI on your bench. It knows when your board is wedged vs. dead, catches power conflicts your firmware can't see, and reflashes bricked targets over the debug port — so your coding agent can run embedded dev unattended. External debug device for embedded boards — no SDK, no code changes. Watch GPIO, ADC and power rails, read CPU and register state, track device life state, catch firmware that runs wrong without crashing, and push OTA with rollback from anywhere.
