    if it’s using I2C,
    how about probing it once

  2. melta101#0000
    February 4, 2025 at 4:18 pm

    manually

  3. ZacckOsiemo#0000
    February 4, 2025 at 4:18 pm

    For context I am trying to get image feed off a imx219-160 camera on a raspberry pi 0 2w in headless mode

  4. ZacckOsiemo#0000
    February 4, 2025 at 4:18 pm

    using something like i2cdetect?

  5. melta101#0000
    February 4, 2025 at 4:18 pm

    it’s trying to do sensor.init() but is unable to read the version ID

  6. melta101#0000
    February 4, 2025 at 4:18 pm

    yep

  7. ZacckOsiemo#0000
    February 4, 2025 at 4:18 pm

    Ok cool let me run it

  8. ZacckOsiemo#0000
    February 4, 2025 at 4:18 pm

    Linux land is just insane

  9. ZacckOsiemo#0000
    February 4, 2025 at 4:18 pm

    `Error: Could not open file `/dev/i2c-1′ or `/dev/i2c/1′: No such file or directory`

  12. ZacckOsiemo#0000
    February 4, 2025 at 4:18 pm

    My cable could be wrong

  13. Ming#0000
    February 4, 2025 at 4:18 pm

    Are you trying to run a camera on a RPi5?

  14. ZacckOsiemo#0000
    February 4, 2025 at 4:18 pm

    on RPi 0 2w

  15. Ming#0000
    February 4, 2025 at 4:18 pm

    OK – similar chip…

  16. melta101#0000
    February 4, 2025 at 4:18 pm

    after that try acessing the chip ID register

  17. 32bitSaviour#0000
    February 4, 2025 at 4:18 pm

    looks to me like an i2c comms issue

  18. Ming#0000
    February 4, 2025 at 4:18 pm

    It could also be not enbaled in the Device Tree

  19. melta101#0000
    February 4, 2025 at 4:18 pm

    i also feel the same

  20. Ming#0000
    February 4, 2025 at 4:18 pm

    Is there an overlay for I2C?

  21. ZacckOsiemo#0000
    February 4, 2025 at 4:18 pm

    software or cable

  22. melta101#0000
    February 4, 2025 at 4:18 pm

    SW

  23. ZacckOsiemo#0000
    February 4, 2025 at 4:18 pm

    I just enabled. i2c on raspi config

  24. ZacckOsiemo#0000
    February 4, 2025 at 4:18 pm

    rebooting

  25. ZacckOsiemo#0000
    February 4, 2025 at 4:18 pm

    then trying again

  26. ZacckOsiemo#0000
    February 4, 2025 at 4:18 pm

    I added an overlay to enable the camera

    I seem to have enabled i2c

  29. ZacckOsiemo#0000
    February 4, 2025 at 4:18 pm

    but no camera yet

  30. Ming#0000
    February 4, 2025 at 4:18 pm

    That’s a distinct lack of camera 🙂

  31. ZacckOsiemo#0000
    February 4, 2025 at 4:18 pm

    I think re hook up the cable maybe its not connected just right.

  32. melta101#0000
    February 4, 2025 at 4:18 pm

    is it logic high?

  33. melta101#0000
    February 4, 2025 at 4:18 pm

    check with a multimeter if the cable is logic high or not

    ifso then it a maybe cable prob then

  34. melta101#0000
    February 4, 2025 at 4:18 pm

    or pinctrl doesnt enable logic high

  35. ZacckOsiemo#0000
    February 4, 2025 at 4:18 pm

    I just watched a video and I realise the guy at the shop might have connected the cable upside down

  36. ZacckOsiemo#0000
    February 4, 2025 at 4:18 pm

    was in a rush and I just wanted it to work

  37. ZacckOsiemo#0000
    February 4, 2025 at 4:18 pm

    rebooting then we can check again

  38. 32bitSaviour#0000
    February 4, 2025 at 4:18 pm

    Hurry potter.

  39. ZacckOsiemo#0000
    February 4, 2025 at 4:18 pm

    Upside down cable and I have signal
