ken 0 Posted September 20 Tinkerboard2 runs 24 hours a day, but sometimes goes down. Is there a Hardware Watchdog feature? I would like to get setup information about WatchDog. Share this post Link to post Share on other sites
tooz 28 Posted September 20 hello @ken, the hardware watchdog is enabled by default. from what you've described sounds like the system shut down because of overheating -- what's the enviornment and was the heatsink attached? please connect tinker board 2s with a usb to ttl serial cable to collect serial logs (instruction can be found here: https://tinker-board.asus.com/forum/index.php?/topic/14971-how-to-enable-serial-console-in-2s/&do=findComment&comment=15287 ) so we know what causes the trouble Share this post Link to post Share on other sites
ken 0 Posted September 21 The environmental temperature is around 25 to 30 degrees and a heat sink is attached. If the CPU temperature is overheated, will it automatically reboot? Or does it shut down? When the system is stopped, only the power LED on and the LAN port lamps all remain OFF. There are 240 identical systems in operation, but only an unspecified unit has occasional problems. (4 ~ 5EA) Share this post Link to post Share on other sites

Or does it shut down? tinker board 2s will shut down if the cpu is overheated i'm not sure whether there's an issue with cpu or ddr, seems like both can be the possible cause. it'd be helpful to have the console log for debugging. are you running the system with os release from tinker board? if so, what's the version of the os?
