Video display froze on TX2 platform

Hi,
The platform is TX2 + Custom Carrier Board
L4T is R32.4.3.
4 IMX219s connected to TX2’s CSI interfaces through TI’s DS90UB954s.2 IMX219s connected to TX2’s CSI interfaces directly.
The issue was:
To run the command
$ gst-launch-1.0 nvarguscamerasrc ! ‘video/x-raw(memory:NVMM),width=3264, height=2464, framerate=21/1, format=NV12’ ! nvvidconv flip-method=0 ! ‘video/x-raw,width=960, height=616’ ! nvvidconv ! nvegltransform ! nveglglessink -e.
The video could display a short time before to be frozen.The time was random and maybe be seconds or minutes.Then the video window had to be closed by pressing Ctrl+C.
The video failed to display to run the above command again.

The command
“v4l2-ctl --set-fmt-video=width=1920,height=1080,pixelformat=RG12 --stream-mmap --set-ctrl=sensor_mode=0 --stream-count=100 -d /dev/video” ran normally but failed after the display freezing.

Looks like signal problem. Suggest to probe the MIPI signal to make sure the it match MIPI spec.
