I have a problem. The picture is complete when it’s not moving, but it’s not complete when it’s moving，See the attachment for the video，the sensor is raw

I’ve seen this behaviour with different sensors.
The cause was an image size like line_length/active_w/active_h was wrongly defined in a device tree.

The log tell “CHANSEL_SHORT_FRAME” that means the output size less than expected.

as you said:
I made the modification, but it is still the same problem.
active_w = “3848”;
active_h = “2168”;
readout_orientation = “0”;

  •                                           line_length = "3800";

  •                                           line_length = "4440";

hi:
Do you have any suggestions for revision, thank you！

It’s doesn’t matter with the line length.

  1. Try to boost the clocks to try.
  2. If 1 doesn’t help modify the driver to report less high also the active_h.
    You can confirm the modification by v4l2-ctl --list-formats-ext

hi:
I want to know which log says, can you paste it, thank you

Below message tell short frame.

hi:
thank you for reply, modify the active_w = “3848”;
active_h = “2168”; solution.
