How does Xavier change save raw file format?

Hi all,
My Xavier received Raw12 data then I use v4l2 command to save raw file.

The saved raw file is 16 bit instead of 12 bit.

And I found some document and forum say the vi5_format.h will set 12 bit data to 16 bit format like that:

D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0 D11 D10 D9 D8

How do I change that to

0 0 0 0 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0

Have a check this for Xavier.

Yes. It’s T_R16

There’s no way to configure as your want. You need remap it after get it from memory.

OK. I got it.
Which document have this image?
Does it has RAW20 schematic?

Next release TRM should have it, current only have T_R16_I schematic.
For RAW20 need to check it.

For RAW20 it could be T_R32 and the layout should be like

D19 D18 …D2 D1 D0 D19 D18…D10 D9 D8
