I have installed watchdog service on OSMC/Raspberry Pi 3. It starts now automatically, but doesn't touch the /dev/watchdog device.
How I check this:
ls -l /dev/watchdog
crw------- 1 root root 10, 130 Dec 17 14:44 /dev/watchdog
ls -l /dev/watchdog
crw------- 1 root root 10, 130 Dec 17 14:44 /dev/watchdog
ls -l /dev/watchdog
crw------- 1 root root 10, 130 Dec 17 14:44 /dev/watchdog
When I touch the device file manually:
touch /dev/watchdog
the file date is changed and if I stop touching this file, the computer reboots after 15 seconds.
Uncommented lines of /etc/watchdog.conf file:
max-load-1 = 24
watchdog-device = /dev/watchdog
realtime = yes
priority = 1
and nothing more, because I want only to check if watchdog service writes to /dev/watchdog file and because I haven't found reliable PIDs to watch.
How to make the service to write in /dev/watchdog ?
