Raspberry Pi 4 Errors

[RHG101997]

Hello, I found your project very interesting and I am playing around with LoRA.

So I am trying to follow you README and when trying to execute it I get different output every time. But most of them are related to GPIO or the one shown in the image.

Also, the "AUX" LED is staying ON some of the time. This is weird cz "echo_test" sometimes works, but it doesn't when the light "AUX" is ON.

Do you have any recommendations as to why I am getting those errors?

Thank you in advance

I found the solution, the problem was enabling serial communication. Serial login needs to be disabled.
