This 3rd version is mainly about code cleanup. Best regards, Regis Jernej Škrabec: I wouldn't add checks on CONFIG_WATCHDOG_HANDLE_BOOT_ENABLED here. My understanding is that this config is already managed in the generic watchdog part, as long as the WDOG_HW_RUNNING bit matches the actual state of the HW watchdog timer. I only saw one reference in a HW driver, stm32_iwdg, where they cannot read the watchdog state, so they start it and set the WDOG_HW_RUNNING bit so that both match.
