HI Team,
we are using Xavier NX with kernel 4.9 and R32.4.3 release.
In it we added device tree entry and camera(ar0821) camera sensor driver. And we also able to get video node(video0).
But when we are running v4l2-ctl command :

v4l2-ctl --set-fmt-video=width=3840,height=2160,pixelformat=RAW12 --set-ctrl bypass_mode=0 --stream-mmap --stream-count=1 --stream-to=ar0821.raw -d /dev/video0

then
we are getting following log :
tegra194-vi5 15c10000.vi: corr_err: discarding frame 0, flags: 160, err_data 1188

and when we checked debug/tracing logs then it show :

 kworker/0:3-1687  [000] ....   156.115694: rtcpu_vinotify_event: tstamp:5202577339 tag:CHANSEL_NOMATCH channel:0x90 frame:33152 vi_tstamp:5202394476 data:0x04000409

The short frame should be the problem. It tell the sensor output didn’t as expected. You may need to adjust the active_h in the device tree to debug it.

tag:CHANSEL_SHORT_FRAME

Now we are getting :

[ 591.413106] tegra194-vi5 15c10000.vi: no reply from camera processor
[ 591.413286] tegra194-vi5 15c10000.vi: uncorr_err: request timed out after 2500 ms
[ 591.413424] vb2-core: vb2_buffer_done: done processing on buffer 0, state: 7
[ 591.413433] tegra194-vi5 15c10000.vi: err_rec: attempting to reset the capture channel

5

That’s tell capture failed and timeout still need to check the trace log to get more information.

6

ok thanks.

Can you let us know why CHANSEL_NOMATCH traces comes ?

7

CHANSEL_NOMATCH tell the channel is not enabled to capture the input stream (or it’s turned on later than the new FS arrives)

Getting this kind of error in traces :
