Frame start syncpt timeout!0 while gstreamer

Hi I’m developing driver for ar1335.

I can read/write without an issue, and my driver currently passes the probe without and error.

v4l2-ctl --list-formats
Index : 0
Type : Video Capture
Pixel Format: ‘GREY’
Name : 8-bit Greyscale

However when I try to execute the following gstreamer command I get the following:

gst-launch-1.0 v4l2src device=/dev/video0 ! “video/x-raw, format=GRAY8, width=(int)1280, height=(int)720” ! videoconvert ! xvimagesink sync=false | dmesg -w

and this same message goes on and on.

Any help ?

Did you probe the MIPI signal to make sure the output signal as MIPI spec?
Does “v4l2-ctl --stream-mmap” get the same error?
