TX2 (board 3326 + ov5693 CSI) with v4l2-ctl RAW data issue (JetPack 3.1 — L4T R28.1 )

Hi all:
I would like to use v4l2-ctl to get the raw data from ov5693 CMOS, and I’ve searched the forum for several days about how to get raw data from CSI(ov5693).
But still can not find a good solution to this issue.

I tried the suggested command:

v4l2-ctl --set-fmt-video=width=1920,height=1080,pixelformat=RG10 --stream-mmap --stream-count=5 -d /dev/video0 --stream-to=ov5693.raw

(because the width is 1920; therefore I think “TEGRA_STRIDE_ALIGNMENT 256” should also work, though I’ve tried 64 also)

The hexdump result shown looks like:(yes, I know the first frame can be ignored)

The RG10 alignment seems wrong to me (because the even bytes for 10bit bayer raw should not exceed 0x04, do I understand correctly?)
Is there anyone who already successfully get the correct raw bayer output?
Any suggestion is greatly appreciated.

After I read the TRM VI chapter, I think “RAW Memory Formats” is quite different from I thought.
