How to let the M.2 work on tx2?

Hi,
I have a brand new tx2, and only runs the installer.sh in the /home/nvidia/NVIDIA-INSTALLER folder.
My M.2 video capture card can be found by lspci on tx1, but can’t be found on tx2.
The version is (uname -a)
Linux tegra-ubuntu 4.4.15 #1 SMP PREEMPT Wed Feb 8 18:06:32 PST 2017 aarch64 aarch64 aarch64(GNU/Linux)

How should I do to let the M.2 work on tx2?

Dear jb035.cheng,

Could you please move this topic to Jetson forum? Since this forum is for Drive Platforms. Thanks.
