RPI.GPIO and Pi4 issue ?

[gordon77]

I can't pull-up all the inputs, and it errors above pin 26...what's wrong ?

Code: Select all

import RPi.GPIO as GPIO
GPIO.setmode(GPIO.BOARD)
GPIO.setwarnings(False)

pins = (3,5,7,8,10,11,12,13,15,16,18,19,21,22,23,24,26,29,31,32,33,35,36,37,38,40)

for pin in range (0,26):
    GPIO.setup(pins[pin], GPIO.IN, pull_up_down=GPIO.PUD_UP)
    print ('pin: '+ str(pins[pin]), GPIO.input(pins[pin]))

gives..

[croston]

I am the maintainer and am working on this.

[gordon77]

Thanks

[gordon77]

Any news on the fix ?

Thanks

[croston]

I'm looking at a fix being available on Sunday.

[gordon77]

Thanks for the info.

[croston]

You can now install the alpha release (for testing purposes):

Code: Select all

$ pip3 install --upgrade --pre rpi.gpio

Let me know if it works or not.

[gordon77]

Thanks, That seems to work fine.

This resolved my problem with RPi.GPIO as well.

Facing problems with GPIO on Pi 4.

Tried the update provided by @croston. But the pip3 install --upgrade --pre rpi.gpio command said that the rpi.gpio is already the latest version and did not upgrade anything.

Are there any further updates or steps to be followed? Have been struggling with this issue for the past couple of days.

Any help would be appreciated.

Hi and welcome to the forum

Unless your problem's identical to this one - best idea is to start your own thread and explain what problem your having

[croston]

This fix is now in Raspbian Buster if you run an update:

Code: Select all

sudo apt update && sudo apt full-upgrade

Thank you!!

I thought the issues I am facing are related to this thread.

As suggested I will start a new thread anyway!

sudo apt update && sudo apt full-upgrade

Thanks for the suggestion.

It did not solve the issue though.

My program works perfectly on Pi 3B+ but not on Pi4

[pcmanbob]

Seeing as you have not actually told us what the problem is I don't see what more help we can offer,

we can only provide help based on the information you provide.

What are you trying to install it in, raspbian ?

Buster should come with it.

Gentoo now uses gcc v10 unless masked, and this has -fno-common turned on by default (upstream). The old default was -fcommon.

This change causes extern omissions in some (usually legacy) code to throw 'multiple definition' errors (like the ones you report) at link time. More details:

https://gcc.gnu.org/gcc-10/porting_to.html#common

You can quickly check whether this is indeed the root issue here (as it may be something else entirely): just add -fcommon to your CFLAGS and see if the target package compiles OK.

If it does then, per the gcc docs, the issue ought really to be addressed in the upstream target package's source.

hth,

Yeap ... it's compiled fine
Thank's Sakaki

Thanks - I'll take a look at this. I've got to check RPi.GPIO behaves properly with the new foundation maintained arm64 distro anyway. I've a couple of compiler warnings with Python 3.9.0b1 to clear up too.
