Linux/EVMX777BG-01-00-00: Does LI-CAM-AR0330-MIPI work with this evm

Part Number: EVMX777BG-01-00-00

Tool/software: Linux

I ordered LI-CAM-AR0330-MIPI for EVMX777BG-01-00-00. Should it work with that EVM out of the box? I don't see a /dev/video1. I am using linux sdk 3.04.00.03. I reinstalled the cable a few times on the "li camera serial" port and it didn't help. I probed the pwr and i2c lines on the li-cam board and they seem to be ok so I think the cable is installed correctly. Should I be using a different camera?

I believe it should be on i2c address 0x20 but i2cdetect doesn't see it.

  • Hi

    AR0330 is not supported on Linux SDK
    By default, only the TI adapter to OV10640 camera is supported.

    Ideally, if the i2c device is powered, you should be able to detect that using i2cdetect.
    To be sure, try reading/writing to the known chip address 0x20 (maybe run i2cdump 4 0x20)
    If the device is not responding, most likely some connectivity issue.

  • I bought the LI-CAM-OV10640-MIPI and now i2cdetect sees a device on 0x33 and 0x6a. It doesn't create a /dev/video1 though. I am wondering if it is looking for a 0v1063x vs 0v1064x i2c device. Where do I change that?

  • Hello,

    Processor SDK supports "dual MIPI CSI adapter connected to OV490 CSI camera"

    Please contact the Field application engineer to get more details on ordering theses parts

    For any other custom camera, if you want to integrate, you will have to write your own V4L2 subdevice driver, add corresponding device tree entries and then the video device will be registered.
