HI nvidia,
When I use the command below on my Orin Nano R35.6.0,dmesg shows errors and sometimes even freezes.
cat /dev/video1

Could you help check my DTS configuration? I’m not sure if the raw8 settings is correct.
Jetson camera framework need some parameter input please using v4l2-ctl to access the video like
v4l2-ctl --stream-mmap -c bypass_mode=0 to capture.
Not really.
When I used the “v4l2-ctl -d 1 --stream-mmap -c bypass_mode=0”, dmesg is still the same.

Looks like NVCSI/VI didn’t receive any validate data from MIPI bus.
You may need have scope to probe the signal to confirm the output follow MIPI spec.
Thanks
I can’t directly measure the signal with either my module or the Orin-nano right now, so I want to first confirm whether there is a problem with my DTS configuration.
You are using devkit or carrier board?
For devkit suggest using CAM1 aka CSI-C to your driver.
I don’t have a devkit or carrier board.

Is it a Line short error issue?
How??
Suppose you are connect the your sensor to devkit. Reconnect to CSI-C to try.
Okay.
Okay.
Still not working.
I modified the GMSL2 configuration,and the /dev/video port output some data.But I still cannot get rawData.dmesg and trace_log .
The current DTS configuration:

};
The trace log shows PIXEL_LONG_LINE,
Confirm the size by v4l2-ctl --list-formats-ext and make sure the sensor output size the same by the driver reported.

From the latest trace_log, how should I determine the line number 0xf1 or 0xf0 ? And for these corresponding issues, how should they be fixed!
PIXEL_EOF
PIXEL_RUNAWAY
PIXEL_SHORT_LINE
Please copy the trace log here instead of screenshot.
Thanks

Because frames are still reaching ATOMP_FRAME_DONE, the recurring fault is more consistent with a format/layout mismatch than with a dead CSI stream:
wrong active width/height
wrong LI/header interpretation
embedded-data presence/length mismatch
datatype / packetization mismatch
frame ending abnormally so VI has to force/interpret FE around bad data
What suggestions do you have on how I should adjust DTS?
