Arducam OV2311 camera not recognized on Raspberry Pi 4B - no cameras available

Hi everyone, I’m stuck with my Arducam 2MP OV2311 Global Shutter NoIR Mono Camera Module on a Raspberry Pi 4B. It used to work on and off (pretty unstable), but after I unplugged and reconnected it, it’s no longer detected at all. I just get:

no cameras available

I’ve been following the quick start guide:
https://docs.arducam.com/Raspberry-Pi-Camera/Pivariety-Camera/Quick-Start-Guide/

What I’ve tried so far:

  • Swapping in different Raspberry Pi boards to make sure the Pi isn’t the problem
  • Formatting the SD card and reinstalling the drivers from scratch

Same result every time. It worked intermittently before, but now nothing. Any suggestions?

Hi, sorry to hear that. Since it was intermittent before and now it’s completely gone, I’d like to rule out the physical connection first. Could you post a couple of photos — one of the connection at the Raspberry Pi end and one at the camera end?

Also, please generate a diagnostic bug report. Reboot the Pi, then run:

wget -O arducam-camera-bug-report https://github.com/Dion4cen/arducam-camera-bug-report/releases/download/Tool/arducam-camera-bug-report
chmod +x ./arducam-camera-bug-report
./arducam-camera-bug-report

That produces an arducam-bug-report.txt file in the current directory. Attach it here along with the photos and I’ll dig into it.

Thanks for the quick reply. I rebooted and ran the tool exactly as you said:

wget -O arducam-camera-bug-report https://github.com/Dion4cen/arducam-camera-bug-report/releases/download/Tool/arducam-camera-bug-report
chmod +x ./arducam-camera-bug-report
./arducam-camera-bug-report

After the reboot the error is still:

*** no cameras available ***

Here’s the generated report:
arducam-bug-report.txt

And the connection photos:

I also tested each component on its own to rule out connector issues, and as far as I can tell everything is seated correctly.

For the record, I already tried switching Raspberry Pi versions and reinstalling drivers after formatting, and the problem persisted both times. It was working intermittently before, but now it’s not showing up at all.

Thanks for the photos and the bug report.

I’ve checked this model, and unfortunately the OV2311 camera module you’re using has been discontinued. That means we’re no longer able to provide support or maintenance for it, and there won’t be any further driver updates or fixes for it.

If you want to stick with a 2MP OV2311 global shutter NoIR mono module, the current equivalent in the PiVariety series is the B0381, which is still actively supported:

If you have questions about the B0381 or how it compares to your current module, let me know and I’ll try to help.
