Watchdog resets that leave no trace — why your device reboots and you'll never know
The watchdog fires, the device resets, and the reset reason register is the only evidence. If nobody reads RCC->CSR (or equivalent) before it's cleared, the event never happened.
Why generic AI tools miss this
Generic AI code review and debugging tools are trained primarily on web and backend code. Watchdog Silent Reset requires understanding of hardware-software interaction at the register level — something that represents a tiny fraction of any general model's training data.
The danger is that a generic tool will give you advice that looks correct but misses the hardware-specific nuance. For watchdog silent reset, the nuance is everything — a subtly wrong answer compiles, links, and flashes successfully, then fails in the field.
Affected MCU families
Watchdog Silent Reset is particularly relevant to these platforms. Each has its own variant of the problem and its own mitigation strategy.
