Part Number: AM5728

Tool/software: Linux

Hello,TI Experts,

I have  TMDSCM572X(camera module) .

Why I checked with ls /dev/video* when my camera is connect and when is not,

there was no differences in the /dev/video entries?

root@am57xx-evm:~# ls /dev/video*
/dev/video0   /dev/video10  /dev/video11

Thanks in advance.

    Hello,

    The camera module is not detected. What is your camera module?
    Please boot the board and execute -
    dmesg | grep mt9t

    If you see no logs, then execute
    dmesg | grep ov10

    and post the log.

    Hello,

    This line mt9t11x 4-003c: Product ID error ffffff87 indicates that your sensor board has either gone bad or the sensor has turned loose.You can try snapping the sensor board tightly to the base board.
    Please, try reconnect the module and use the screws to fix the camera module also.
    If you have ov10635 based sensor board, you could try with it also.
