Quad camera hat seemingly broken?

[epoliquin]

1. Where did you get the camera module(s)?
   uctronics
2. Model number of the product(s).
   B0388
3. What hardware/platform were you working on?
   pi 3b+ and cm4 with bullseye
4. Instructions you have followed. (link/manual/etc.)
   Raspberry Pi libcamera Guide - Arducam
5. Problems you were having.
   i originally got the quad camera hat to work on a 3b+. plugged it into a cm4, after the second boot the LED on the quad hat stopped turning one, now it doesn’t work on the 3b+ either. after following all the steps to install the drivers i get

[email protected]:~ $ libcamera-still --list-cameras
[0:04:17.543949614] [1230] INFO Camera camera_manager.cpp:293 libcamera v0.0.0
No cameras available!

I have regular IMX519 modules from arducam that work fine, so the driver’s installed correctly.

6. The dmesg log from your hardware.
   i dont get any dmesg

7. Troubleshooting attempts you’ve made.
   different OS, different hardware, check cables, different order of installing apps, restart, different power cables/PSUs

8. What help do you need?
   is this board bricked? do i need to get a new one?

I think I still need more information to diagnose the problem:

Before you ask questions about libcamera and camera drivers

Before you ask questions about libcamera and related drivers, please provide the following information: System related information can be obtained by the following command: uname -a cat /etc/os-release cat /proc/meminfo cat /boot/config.txt System log dmesg Camera Module Module number(e.g. SKU) or purchase link Photo of hardware connection (This is important.) Application log Provide error information or screenshots of application output

You also need to provide the output of the following command:
i2cdetect -y 10

Note: Make sure the Quad HAT is connected.

The hat is definitely connected. I’ve reseated all the cables on the board at least a dozen times now. Here’s the I2Cdetect output

If you make sure all the hardware connections are correct, then unfortunately it seems that the HAT is damaged or there is a problem with the cable from the HAT to the Raspberry Pi, because from the i2cdetect results, the HAT is not detected correctly.
