Issue Description

I am trying to use realsense with Jetson TX2 (jetpack 3.2.1). Also, I tried to install this camera with several guidelines with Jetpack 3.3 as well. BUT, All failed to connect the camera.

I took 6 days to connect a realsense D435i.. but still failed.. please help me.

I followed below to install the realsense lib.

1. Install Jetpack 3.2.1 with host PC.

2. Install realsense as below.

git clone https://github.com/IntelRealSense/librealsense.git cd librealsense git branch v2.9.1 git checkout -b v2.9.1 sudo apt-get update sudo apt-get install git cmake sudo apt-get install libssl-dev sudo apt-get install libusb-1.0-0-dev pkg-config libgtk-3-dev sudo apt-get install libglfw3-dev sudo apt-get install libudev-dev sudo apt-get install cmake-curses-gui sudo cp config/99-realsense-libusb.rules /etc/udev/rules.d/ sudo udevadm control --reload-rules && udevadm trigger reboot Build and Install librealsense mkdir build && mkdir install set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -pthread") cd build cmake ../ -DBUILD_EXAMPLES=true -DCMAKE_BUILD_TYPE=release -DBUILD_UNIT_TESTS=false make -j4 sudo make install

I tried another installation guide such as Jetsonhacks, but it also shown no devices detected.

Have you seen the official documentation page for installing Librealsense on Jetson TX2 and performed the steps recommended in that guide, please?

https://github.com/IntelRealSense/librealsense/blob/master/doc/installation_jetson.md

[dorodnic]

This part:

git clone https://github.com/IntelRealSense/librealsense.git
cd librealsense
git branch v2.9.1
git checkout -b v2.9.1

Doesn't look right. v2.9.1 was released long before D435i was a product. JetsonHacks just published a tutorial on the D435i: intel-realsense-d435i-on-nvidia-jetson-agx-xavier/ Perhaps it could help

@dorodnic

Thank you for the comment. I tried the tutorial already with Jetpack 3.3 and Jeptack 3.2.1 and I faced on same problem.

@MartyG-RealSense

Thank you for the comment. I checked the official site first, and my windows laptop already set up based on the information provided by official site. However, the install guide for Jetson TX2 is not existed. So, I follow another install guide such as Jetsonhacks and etc. I reset Jetson TX2 board several time with Jetpack 3.2.1 and Jetpack 3.3 before following the install guild for removing any interruption.

And the official documentation page what you mentioned.. said, edit patch-realsense-ubuntu-xenial.sh. BUT, I can't find patch-realsense-ubuntu-xenial.sh in /librealsense/scripts dir.

Please help.

[MartyG-RealSense]

Apparently, if you are using Kernel 4.15 or newer then the patch script is no longer needed. There is a download link in the message linked to below if you want it though.

Hi @sophie-shin,

For TX2, refer to the build process in below link. In order for librealsense to work properly, the kernel Image must be rebuilt and patches applied to the UVC module and some other support modules. In addition, for support of the extra features of the D435i camera such as the IMU, extra modules must be built. These modules are in the Industrial I/O ( IIO ) device tree. The Jetson already has IIO support enabled in the kernel image to support the INA3321x power monitors. To support these other HID IIO devices, IIO_BUFFER must be enabled; it must be built into the kernel Image as well. https://github.com/jetsonhacks/buildLibrealsense2TX

Make sure to run the script "buildPatchedKernel.sh" correctly. Then, above kernel patches especially for HID IIO devices should be applied. If this is ready, you should be able to run D435i video and IMU streams.

Hi @sophie-shin,

Make sure to use the latest librealsense like 2.18.0.

[sophie-shin]

Thank you all,

buildPatchedKernel.sh fixed it correctly.

This solution is out of date.So,how can I install D435i driver on Tx2(Jetpack4.2)?
