How to make hardware reset

Proshutyan

I can't find any info how to make hardware reset on the Orange Pi Plus board.
I bought a watchdog USB dongle that will reset the Orange, like attached picture.
My orange will be used in close space with limited access.
But i have no idea how to connect dongle to the Orenge reset.
Does anybody know any pull-up system reset resistor or supervisor uc on this board where I can solder wire?
I'll be very grateful for the help

Dont know your particular kernel, but with Armbian you just write:

echo 1 > /dev/watchdog

now it is armed and you have to repeat the echo command every 15s.
If you forget it, the device is hard reset after about 20s.

No need for extra hardware.
