Input/Output Usage and Wifi

Hello Everyone, How to access inputs and outputs in the original image?
Also, where I can find information about how to setup WIFI. Or even DTS? So I can see what is configured.

Many Thanks,

GPIO 86 is used as the IO pin to switch the WIFI module

Among them, the SSW101B WIFI function is output low, and the USB function is GPIO output high

After that manually install the ssw10b.ko driver file, you can see the WiFi device

Finally, you can connect through tools such as wpa.
