Thanks Laurent.
I've appended console output to the commands you've suggested.

Ok I solved the segfault problem by updating some of my v4l2 files
(specifically v4l2-common.c). Now I only get nice sounding console

As you're using an MT9V032 sensor, I can help you with the pipeline setup. You
can run the following commands to capture 5 raw images.
./media-ctl -r -l '"mt9v032 2-005c":0->"OMAP3 ISP CCDC":0[1], "OMAP3 ISP
CCDC":1->"OMAP3 ISP CCDC output":0[1]'

And then it hangs. I'm trying to run a bt but I think mbus->code=0x0000
is the problem. Not sure where it stems from though. Thoughts?
