I chose the xavier development board, the camera is ov2775, after loading the camera driver, execute the command:
V4l2-ctl --set-fmt-video=width=1920,height=1080,pixelformat=BG12 --stream-mmap --stream-count=100 -d /dev/video0
The tips are as follows:

From the trace log the problem should be the sensor didn’t send the FE(frame end) package.
Execute v4l2-compliance test, there is a test problem, is there a correlation?
sudo v4l2-compliance -d /dev/video0

“Could not find ctrl 9a2002” is what caused it, “test VIDIOC_G/S_PARM: FAIL” is what caused it, how to solve it？
Don’t bother it. That FAIL won’t case capture failed.
Consulte to sensor vendor to make sure the FE package problem.
