Hi all,

    I have troubled with my imx6ul camera for some days. I used adv7181 on my imx6ul custom board,  now ,I have already moved the 7181's driver to my 4.1.15 BSP. The driver is refer to the adv7180.c , and now , the device has been already registerd, the signal of clock and  adv7181's 8 output data signals are all right . But when I use '/unit_tests/mx6s_v4l2_capture.out -m 0 -d /dev/video0' to test my driver, there is a error log just like this

  'Found v4l2 capture device /dev/video0.
  VIDIOC_S_PARM failed'

I am not sure whether my test method is wrong or my driver have some other  problems. Someone could  give me some advices?

 

With my best regards

Jun
