Looking at the MCU code it seems that the watchdog can be started again after being disabled, so it could theoretically be used as a normal watchdog. The problem is that it cannot be pinged to reset the counter. It has to be stopped and started again, meaning there is a small window when it is disabled. If the system used this watchdog, this small window would make it vulnerable, so I don't think we should use it. >> Shall I resend this series with this new patch? > Yes, please do. Will do. Marek
