I have a RPI v2.1 hooked up to my RPi but haven't tried it yet.

I have only run OpenCV on my windows computer.

What code are you using? Python or c++?

You realise there is no way anyone can guess what might be wrong without checking all the steps have been taken? Are you for example following some tutorial on setting up the RPi + camera? When I get around to playing with the hardware and setting up opencv I will find a tutorial to follow. So what tutorial are you using?

This is the hardware I was going to use until I saw the RPi was not being built anymore so I gave up on it.

@robotbuilder sorry I fell asleep. It's actually Paul McWhorter  raspberry pi lesson 63 the code is only as far as the preview the pi camera code runs no error but the camera doesn't turn on . On the web cam the code runs then error at imshow('Camera',im). I'm hearing picam2 and libcamera are having problems in open cv I'm on thonny thanks😁👍

Paul's tutorial on the installation of OpenCV and its use seems to start with lesson 45:

I am too busy for the next week or so with other things so I don't have time to work through it myself.   In the meantime it is back to scouring the internet for clues and making sure you made all the right steps.
