Hi Luke,
There are some hardware incompatibilities that are still being worked out in the latest Raspberry Pi ‘Bullseye’ release which means some cameras may not work with the new camera library functions when running older Raspberry Pi boards like the Pi 3A+.
There is a software solution to this, you just need to use the older ‘Buster’ release and then the Raspistill commands covered in our older camera guide will work fine.
This guide covers how to flash buster.
This guide covers how to use the older camera library commands.
I’ve tested a Pi3A+ today with Buster and a wide angle camera module.
You can view a stream from the camera using the terminal command.
raspistill -p 100,100,640,480 -t 0
You can then kill the video window using CTRL + C or CTRL+SHIFT+Q in the terminal.
