We’ve recently come upon a new (to us) issue. We have a microscope that was previously working. We are connecting to it locally, but now when we click “Connect”, we get a message stating “Stream preview disabled”. Occasionally, we will also get an error “500: deque mutated”.
So far, we have tried:
- Replacing the camera module.
- Replacing the FFS cable.
- Replacing the Raspberry Pi (but using the same SD card).
- Reimaging the SD card with a fresh installation of the OnlyFlexure Raspbian OS.
- Enabling I2C in Raspi-config, which at least results in a different error: "500: No data recieved from sensor. Check all connections, including the SUNNY chip on the camera board.
We also saw that there’s a an option to “Disable web stream” under Display Settings. That box appears to be checked by default. When we uncheck that box, the preview screen displays a message stating “Camera disconnected”, followed by the clock.
The camera is shown as being supported and detected using “vcgencmd get_camera” in the terminal.
I’m sure there’s probably something obvious we’re overlooking, but I didn’t see anything else on the forum related to this issue. Has anyone encountered it before or have suggestions on how to resolve it?
Thanks.
