Hello forums,
I am using TX2 with Jetpack4.2-R32.1 to driver a pre-configured csi video（1080P@60fps UYVY, 4lane)
when I use V4L2 Test Bench to grab video stream I got bellow error:
[ 126.377747] tegra-vi4 15700000.vi: PXL_SOF syncpt timeout! err = -11
[ 126.384193] tegra-vi4 15700000.vi: tegra_channel_error_recovery: attempting to reset the capture channel

[ 126.824479] tegra-vi4 15700000.vi: tegra_channel_error_recovery: attempting to reset the capture channel
and /sys/kernel/debug/tracing/trace captured nothing when I use v4l2-ctl:
root@nvidia:~# sudo v4l2-ctl -d /dev/video0 --set-fmt-video=width=1920,height=1080,pixelformat=UYVY --set-ctrl bypass_mode=0 --stream-mmap --stream-count=1 --stream-to=tt.raw

Ｔhere’s no data for the trace? Did you enable it before capture by v4l2-ctl?

sorry, it’s my bad.
here is the capture log:

The trace log shows didn’t get any validate data from MIPI bus. You may need to probe the signal to make sure of it.

Okay, thanks ShaneCCC.
other thing I want to know, if mipi csi data changed from 1080P@30pfs to 1080P@60fps, is it necessary to modify the kernel code and dtb?
No need for bring up, you can modify it after all things are up.

i am getting below error on ov2735 can any one help on this
The trace tell the NVCSI/VI didn’t receive any validate package from the MIPI bus.
