I have an raspberry py 2 running debian stretch and I have done all procedures to load watchdog, but I can't get module to work....it just doesn't show anything, even error! I can see watchdog 'device', but I can't see any watchdog module loaded. I have the correct lines added to my /boot/config.txt, but still not working.

root@skyweather:~# modprobe bcm2709_wdog

    This question has many problems. Firstly you have 4.14.41-v7+ which is am unsupported testing version. What are "all procedures to load watchdog"? I don't know why you think modprobe bcm2709_wdog will show anything. I don't know about Debian but watchdog works perfectly on Raspbian. – Milliways May 27 '18 at 4:16
  • please add result of cat /etc/os-release – Fabian May 27 '18 at 13:33
