Install and Setup Prerequisites for NVIDIA Boards

Target Requirements

Hardware

GPU Coder™ Support Package for NVIDIA^® GPUs supports the following development platforms:

NVIDIA Jetson AGX Xavier platform.
NVIDIA Jetson TX2 embedded platform.
NVIDIA Jetson TX1 embedded platform.
NVIDIA DRIVE PX2 platform.

The GPU Coder Support Package for NVIDIA GPUs uses an SSH connection over TCP/IP to execute commands while building and running the generated CUDA^® code on the DRIVE or Jetson platforms. Connect the target platform to the same network as the host computer. Alternatively, you can use an Ethernet crossover cable to connect the board directly to the host computer.

Software

Use the JetPack or the DriveInstall software to install the OS image, developer tools, and the libraries required for developing applications on the Jetson or DRIVE platforms. You can use the Component Manager in the JetPack or the DriveInstall software to select the components to be installed on the target hardware. For installation instructions, refer to the NVIDIA board documentation. At a minimum, you must install:

CUDA Toolkit
cuDNN Library
TensorRT Library
OpenCV Library

Install the Simple DirectMedia Layer (SDL v1.2) library, V4L2 library, and V4L2 utilities for running the webcam examples.

Environment Variable on the Target

GPU Coder Support Package for NVIDIA GPUs uses environment variables to locate the necessary tools, compilers, and libraries required for code generation. Ensure that the following environment variables are set.

Variable Name Default Value Description

Variable Name	Default Value	Description
`PATH`	`/usr/local/cuda/bin`	Path to the CUDA toolkit executable on the Jetson or DRIVE platform. Ensure that the path to the CUDA toolkit executables should be accessible in non-interactive SSH logins. For example, this can be done by adding the following `export` command at the very beginning of the `$HOME/.bashrc` file for bash profiles. `export PATH=$PATH: /usr/local/cuda/bin`
`LD_LIBRARY_PATH`	`/usr/local/cuda/lib64`	Path to the CUDA library folder on the Jetson or DRIVE platform.

PATH

/usr/local/cuda/bin

Path to the CUDA toolkit executable on the Jetson or DRIVE platform.

Ensure that the path to the CUDA toolkit executables should be accessible in non-interactive SSH logins.

For example, this can be done by adding the following export command at the very beginning of the $HOME/.bashrc file for bash profiles.

export PATH=$PATH: /usr/local/cuda/bin

LD_LIBRARY_PATH

/usr/local/cuda/lib64

Path to the CUDA library folder on the Jetson or DRIVE platform.

Input Devices

A webcam connected to the USB host port of the target hardware.
