Nanopi M1 GPIO problem

[Chun]

Hello guys, I am new to this forum and this is my first thread.

 

I bought a Nanopi M1 and try to play with the GPIO.

I follow all the official instruction and install MatrixGPIO-python

However, after the installing, I would like to test the GPIO with script that come with the Git Clone

The terminal shows me this response "Fail to set gpio direction"

 

Does anyone know how to solve this problem?

Thank you
