VD56G3 compatibility with Raspberry Pi CM5 module + CM5IO board

3FTI · ‎2025-07-02

Do the current VD56G3 drivers support the CM5 module?

I have followed the installation guides several times (including building libcamera from the ST source files) and I can't get libcamera to stream the camera. Here is the error message:

Hello 3FT,

Our Software is working on the subject they confirm the issue and try to solve it.

i will give you more information soon

Thank

bye

3FTI · ‎2025-08-01

That's great, looking forward to resolving this issue so we can continue with the development.

MeganeG · ‎2025-08-11

Hi @3FTI,

We have updated our driver to support the Raspberry Pi Compute Module 5. The latest version is now available on st.com.

Please note that the device tree overlay usage has changed:

CM5 supports only the cam0 connector.
Cam1 is now the default camera connector. To select cam0, add ",cam0" at the end of your dtoverlay line, for example: dtoverlay=youroverlay,cam0.

Thanks, Megane.

Hi @MeganeG, awesome, thanks. I will give this a try and report back.
