Hi @AnshumanFauzdar
Just letting you know we are looking at it. Seems like an issue where camera is not even recognized. I'm pretty sure it should work though, so I'll let you know when I find a solution.

Thanks,
Jaka

    Just following up with some additional details @jakaskerl

    I purchased a brand new Arducam ToF, and a Raspberry Pi Camera Module 3.

    I validated each camera's operation using a fresh Raspberry Pi CM4 Bullseye 64-bit image and a CM4 Base Board.

    Then, I plugged the verified CM4 and camera into the OAK-D-CM4, but neither of the 2 cameras worked.
    Each time, it looks like the dmesg errors are around i2c probe failures.
    i2cdetect finds the specific i2c address for each camera module, but each registers poll "ff"

    Let me know if there are any specific tests you would like me to run; I'm happy to help.

      CyrilEngmann I tried raspi-config to enable camera but there is no option showing up:

      and when checking with libcamera-hello it shows this:

      eir@cm4:~ $ libcamera-hello --list-cameras

      No cameras available!

        Hi @CyrilEngmann thanks,

        I tried with two different RPI cameras. But can not get any i2c readouts at all (no dmesg messages when replugging the camera). In order to recognize the camera it has to be connected to RPI at bootup. When trying that with OAK-Cm4, the device fails to boot due to some power(?) issue.

        That's what I'm looking into currently.

        Thanks,
        Jaka

          jakaskerl with OAK-D CM4 device is powering ON without any power issue [Using power supply delivered with OAK-D CM4] but camera is not recognized as shown in above reply.

            Hi @AnshumanFauzdar
            We found a HW bug that made it so the device couldn't boot with CSI camera connected and therefore couldn't find the camera with lib-camera library.

            Now it seems there is another I2C issue, which we are looking to fix atm.

            Thanks,

              PMIC_EN was pulled low by the CM4 when RPi camera module was inserted.

              The intermediate solution was that the trace was cut and now the device boots up normally, due to PMIC having an internal pull-up on PMIC_EN.

              Thanks,
