Hi There !
I have a Orange Pi 3 (H6 SOC I suppose) and I am trying to enable watchdog reset.
As far I can see, there is no kernel module for it, and, as result, there is no /dev/watchdog device file.

I've installed watchdog package and added the line "extraarg=sunxi_wdt.nowayout=1" to /boot/armbianEnv.txt
What am I missing ?
