Does the same trace log from #5? From the image it looks like only get one line data that could be the width report by driver is not match the sensor output. You can try reduce the width from the sensor driver to try an error to figure it out.
v4l2-ctl --list-formats-ext can show the resolution to make sure your modification.
Ok, my sensor is outputting RGGB12 and I set my default datafmt to RGGB12 in the driver, yet v4l2-ctl is returning RG10. The resolution is correct though. Here are the results:
nvidia@tegra-ubuntu:~$ v4l2-ctl --list-formats-ext
ioctl: VIDIOC_ENUM_FMT
Index : 0
Type : Video Capture
Pixel Format: 'RG10'
Name : 10-bit Bayer RGRG/GBGB
Size: Discrete 3704x2778
Interval: Discrete 0.033s (30.000 fps)
Also, in v4l2-compliance I get:
Format ioctls:
info: found 1 frameintervals for pixel format 30314752 (RG10) and size 3704x2778
info: found 1 framesizes for pixel format 30314752 (RG10)
info: found 1 formats for buftype 1
test VIDIOC_ENUM_FMT/FRAMESIZES/FRAMEINTERVALS: OK
fail: v4l2-test-formats.cpp(1184): ret && node->has_frmintervals
test VIDIOC_G/S_PARM: FAIL
test VIDIOC_G_FBUF: OK (Not Supported)
fail: v4l2-test-formats.cpp(434): pixelformat 32314752 (RG12) for buftype 1 not reported by ENUM_FMT
I have it reporting RG12 now, but the output is still the same (attached). Changing the frame length, exposure time, etc. in the driver has no effect, neither does changing the line_length in the dtsi.
I would rather suggest to use raw 12 due to we didn’t have any reference 14 bit sensors for QA test yet.
Also could you share your sensor driver and DT to contribute to others tegra forum user.
