A physical pull up resistor is fitted on this channel!

[dotmick]

Hi there,

I am currently facing a problem that makes my GPIOnext not working. But it was yesterday :/

Here are the pins I am using 3,5,7,8,9,12,31,33,35,36,37,40.

And the message I do get:

May 18 18:22:14 retropie systemd[1]: Started gpionext-daemon.

Any idea why?

Thanks!

The "physical pull up resistor is fitted on this channel!" is just a warning that pops up when you use pins 3 or 5, it's nothing to worry about.
The problem is that pin 9 cannot be used as it is a ground.

@mholgatem yep, you're right. I've made a mistake and it should be 10 instead of 9.

Thanks for pointing that out!

no problem
