I use the jetson tx1 and R28.2
1.I use command “v4l2-ctl --all”,then output is :

nvidia@tegra-ubuntu:~$ v4l2-ctl --all

2.Then I will get the sensor raw data,but the abc001.raw file all data is 0.

v4l2-ctl -d /dev/video0 --set-fmt-video=width=3280,height=2464,pixelformat=RG10 --stream-mmap --stream-count=1 --stream-to=abc001.raw

3.Who can help me fix this question?
