Issue Description

To install librealsense on Jetson TX2 I have read these readme files:
installation_jetson.md
distribution_linux.md
JetsonHacks: buildLibrealsense2TX/README.md

So, as I understood to install librealsense on Jetson TX2 I should follow instructions from distribution_linux.md except for one moment about kernel patching.
Here is the problem.
Instruction from installation_jetson.md is inapplicable because instructions contains out-of-date links to patch scripts.
Another way to patch kernel is to run JetsonHacks scripts.
buildPatchedKernel.sh from JetsonHacks is inapplicable because I dont have kernel in my /usr/src/kernel directory. Moreover, installLibrealsense.sh installs librealsense v2.13.0 instead of latest 2.25.
Do I understand something wrong?
What can I do to patch kernel and install librealsense properly on my Jetson TX2?

We will update installation_jetson.md soon with new instructions.

distribution_linux.md except for one moment about kernel patching

This is correct.

What can I do to patch kernel and install librealsense properly on my Jetson TX2?

We no longer recommend kernel patching for Jetson installation. Installing the SDK via apt should be entirely sufficient.

@dorodnic is there any time frame on these updates? Installing via apt seems to not work at the moment (apt complains that there is no release for arm64).

@dorodnic Really looking forward it! Is there any expected time?

@studennis911988 - I just created a pull-request with updated instructions (#5053)
@brandonhanner - can you share more details? Are you using Ubuntu 16 or 18? (I think we published the 18 version also but I may be mistaken) Did you get any errors during the process?

[studennis911988]

@dorodnic
First of all, really appreciate all your hard-work.
Before jump right into the new installation, I have two concerns.

1. Does it mean that the new installation process is independent to the Jetpack or L4T version?
2. Does the new installation tested on D435i? Since I have noticed that only firmware 5.10.03 is able to connect D435i to my NVIDIA TX2 , moreover, D435i can only be recognized as D435 and the emitter is disable in this firmware. Just like this issue

Hey @dorodnic, thanks for the updated instructions. My colleague was able to get this working with our T265 on the latest nvidia jetpack release with Ubuntu 18.04 LTS

[sjdrc]

Does the nvidia provided kernel now have support for frame metadata?

This works for me! Thank you!

@dorodnic thanks for your work and reply!

I have installed librealsense via apt on my jetson tx2 and I got d435 working in ros, but after some time it stops working and I see this error:

[camera/realsense2_camera_manager-5] process has died [pid 3038, exit code -11, cmd /opt/ros/kinetic/lib/nodelet/nodelet manager __name:=realsense2_camera_manager __log:=/home/nvidia/.ros/log/6312e40e-f6fb-11e9-9e19-b42e994ddade/camera-realsense2_camera_manager-5.log].
log file: /home/nvidia/.ros/log/6312e40e-f6fb-11e9-9e19-b42e994ddade/camera-realsense2_camera_manager-5*.log

What does mean code -11? Is this related to wrong librealsense installation on jetson tx2?

@jungladicitta @dorodnic
I had installed SDK successfully and the performance is quite nice, but I encountered the same issue as @jungladicitta does, the ros-wrapper dumped occasionally and the system become very laggy when using ros-wrapper even if the cpu use rate is under 50%.
@dorodnic wish you can give us some hint, thanks in advanced!

@dorodnic
Also I have issue that t265 disconnects when d435 is connected even with using powered USB 3.0 hub. Check out the description #5129
What do you think?
