vd66gy with Raspberry Pi5: Failed to Queue Buffer

[Erebos]

I am using a pcb4188_vd66g1 camera module with a Raspberry Pi 5.

The system has been freshly set up with Raspberry Pi OS 64-bit, and I followed the official setup guide step by step.

After completing the setup:

• The camera is detected correctly when running rpi-hello --list-cameras.

 

• However, when I run rpi-hello, no image is displayed (black screen), and an error message appears (see attached screenshot). Modified versions of the command do not work either

 

• The camera is also recognized at startup (dmesg as well), as confirmed by the output of v4l2-ctl --list-devices.

 

 

I have also read through several forum threads on this topic and have already tried many of the suggested troubleshooting steps, but the issue persists.

Could you please help me identify what might be causing the problem and how to resolve it?

Additionally, I noticed the following behavior:

• During setup, I only ran sudo apt update but did not perform a full upgrade.
• After running a full system update/upgrade later, some Raspberry Pi firmware updates were installed as well as rpi updates, and the camera stopped being detected by rpicam-hello --list-cameras.

Also there was a fragment warning but I don't think it is concerning (but I'll just mention it)

Hello @Erebos ,

This is the first time we observe this issue. I cannot reproduce it with the same setup as you.

As your camera is well detected and grabbed by libcamera, the issue does not seem to be on software side. 

The problem might come from the hardware; do you have another flex connector to try?

BR,

Jean

Hey,

I tried out another flex connector and another board/ sensor as well. Turns out that the connector is fine but the board os not working properly.

Thanks for your support
