VD55G0 not detected on Raspberry Pi 5

[asdfasdf]

Dear all,

I'm trying to get a VD55G0 sensor (promodule connected via P-board) working on a Raspberry Pi 5. I followed the Linux Start Guide for the driver. The only difference with respect to the guide were the name of the device tree file (guide says pcb4189.dts which the repository does not contain, so I used pcb4189_vd55g0.dts), and the names of the libcamera packages (the filenames seem to have changed, I have installed both .deb packages from the STSW-IMG505_RPI download). However, the camera sensor is not detected at all:

$ rpicam-hello –-list-cameras

$ ls /sys/bus/i2c/drivers
dummy  stmpe-i2c

$ uname -r
6.12.62+rpt-rpi-2712

There is some output in the system log regarding the sensor, but I'm not sure what to make of that:

Here is a photo of the physical setup, I think I have matched what is written in the Guide:

I know that the camera sensor and P-board are working (have already used it on a STM32N6-DK board), so this is very likely a software issue.

Any ideas what the problem could be, or how I could debug this?

Thanks a lot!

Hello Michael, 

Your device tree seems not well apply, could you change de device tree to pcb4280 to match with board pcb number.

This should not solve the issue,

Can you  add ,cam0  in config.txt  like this "dtoverlay=youroverlay,cam0"

I will change the guide.

Cyril

Thanks @CyrilTechPro , I got it to work! There were two problems. First, the Guide recommends installing the driver with `sudo cp *.ko /lib/modules/$(uname -r)`. However, apparently my kernel version changed afterwards (maybe due to `apt update` - not sure here, could also be some auto-upgrade of the Raspi running in the background). Of course the result is that the driver simply was not there anymore... After I fixed that (by re-installing the driver), there was still an issue, this was solved by adding `,cam0` when configuring the device tree overlay, as you recommended.

Thanks again!

Michael

Dear all,

I also use vd55g0 and raspberry pi5, and currently, I can detect the camera. However, when I start the camera capture, an error occurs.
