Orange Pi 3 - GPIO as Input flashing

Recommended Posts

Hi everyone,

I am trying to set the pin 26 (PL08) on orange pi as Input but sometimes it is flashing.

I did  put a 10K external pull up resistor and it is exported as input pin.

I did the same thing with the pin 22 (PD21) and this one is steady, no problems until now. 

I did not add anything on overlays for these pins.

Any idea what I am doing wrong?

Pull up or pull down the pin using built-in 50k resistors. And compare the results. 

Is it possible to have an example of how I can do that with an overlay maybe?

I tried with gpio mode *pin number* up and also down but it doesn't seem to work. I tried using sunxi-pio but no changes are made.

Thank you
