Scratch 3 Raspberry Pi GPIO extension does not work on RPi5

[penguintutor]

Running Scratch 3 on a Raspberry Pi 5; the GPIO extension does not work.

It is not correctly detecting any of the GPIO ports.

I have tested using Bookworm on a Raspberry Pi 4 which works correctly, and I have also tested wiring of the GPIO on the RPi5 using the same ports with GPIOZero.

To recreate this then you can start with a basic example:

This is a basic example showing simple code to test which is added to the default sprite. GPIO 2 is connected via a switch to ground.

When run the Scratch cat will move across the screen whether the button is pressed or not. It should only move when the button is pressed.

I have also tested setting a GPIO pin high to drive an LED which does not work either.

This is not related to the 16KB segmentation fault as far as I can tell.

I am able to get Scratch running both on the 32-bit Raspberry Pi OS. I've also got it working using the 64-bit version using kernel8.img.

It is the GPIO extension which is not working and always gives a "high" when set to an input, and is not working when set as an output.

I suspect this is that the GPIO extension is not aware of the changes to the GPIO using the RP1 and so may need to be updated

same for me...i can use other futures in Scratch3 with RPi5...but couldnt use these extension Raspberry Pi GPIO and Raspberry Pi Sense HAT. Anyone can help me out ?

The latest 3.30.8 release fixes issues loading the GPIO and Simple Electronic extensions:

64-bit: https://archive.raspberrypi.org/debian/pool/main/s/scratch3/scratch3_3.30.8_arm64.deb

32-bit: https://archive.raspberrypi.org/debian/pool/main/s/scratch3/scratch3_3.30.8_armhf.deb

SenseHAT issues have a fix incoming...
