In orange pi one plus change mode on wPi 1 to off will make system break down #29

I try to use wiringOP in my one plus, but when I set mode of wPi 1 to off, the system will break down. But the wPi 1 original mode is off. If I set it to out or in will be all right.

This happens to me too. This was the reason why I had to enable the watchdog service for /dev/watchdog. Anyway, when I do:

gpio mode 9 OFF

the board freezes. Nothing is printed to the serial console and I can't send commands to it or via wi-fi. so I'm not sure how to troubleshoot it. My board is Orange Pi Lite with Armbian 21.02.1 Buster with Linux 5.10.12-sunxi

When GPIO is OFF, it means IO disable. At present, GPIO can only be set as input or output, but cannot be set as OFF.

In addition,

gpio mode 9 OFF

It is used to set the up and down resistance of GPIO port. It is not fit at present.
