Install and Setup Prerequisites for NVIDIA Boards

Target Requirements

Hardware

MATLAB^® Coder™ Support Package for NVIDIA^® Jetson™ and NVIDIA DRIVE™ Platforms supports the following development boards:

• NVIDIA Jetson Xavier™ NX.

• NVIDIA Jetson AGX Xavier.

• NVIDIA Jetson Nano™.

• NVIDIA Jetson TX2.

• NVIDIA Jetson TX1.

• NVIDIA DRIVE PX2.

The support package uses an SSH connection over TCP/IP to execute commands while building and running the generated code on the DRIVE or Jetson platforms. Connect the target platform to the same network as the host computer. Alternatively, 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.

  • GStreamer library (v1.0 or higher) for deployment of the videoReader function.

  The MATLAB Coder Support Package for NVIDIA Jetson and NVIDIA DRIVE Platforms has been tested with the following JetPack and DRIVE SDK versions:

  Hardware Platform	Software Version
  Jetson Xavier NX, AGX Xavier, TX2/TX1, Nano	JetPack 4.4.1
  DRIVE	DRIVE SDK 5.0.10.3-12606092

• Install the Simple DirectMedia Layer (SDL v1.2) library, V4L2 library, and V4L2 utilities for running the webcam examples. You must also install the development packages for these libraries.

• For deploying the Audio File Read Simulink^® block, install the Sound eXchange (SoX) utility and its development and format libraries.

  For example, on Ubuntu, use the apt-get command to install these libraries.

  sudo apt-get install libsdl1.2-dev v4l-utils sox libsox-fmt-all libsox-dev
  

Environment Variable on the Target

The support package 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
PATH	/usr/local/cuda/bin	Path to the CUDA toolkit executable on the Jetson or DRIVE platform.
LD_LIBRARY_PATH	/usr/local/cuda/lib64	Path to the CUDA library folder on the Jetson or DRIVE platform.

Ensure that the required environment variables are accessible from non-interactive SSH logins. For example, you can use the export command at the beginning of the $HOME/.bashrc shell configuration file to add the environment variables.

 Example .bashrc File

# ~/.bashrc: executed by bash(1) for non-login shells.
# see /usr/share/doc/bash/examples/startup-files (in the package bash-doc)
# for examples

# If not running interactively, don't do anything
case $- in
    *i*) ;;
      *) 
         export PATH=$PATH:/usr/local/cuda/bin
         export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda/lib64
         return;;
esac

# don't put duplicate lines or lines starting with space in the history.
# See bash(1) for more options
HISTCONTROL=ignoreboth

# append to the history file, don't overwrite it
shopt -s histappend

# for setting history length see HISTSIZE and HISTFILESIZE in bash(1)
HISTSIZE=1000
HISTFILESIZE=2000
.
.
.

Alternatively, you can set system-wide environment variables in the /etc/environment file. You must have sudo privileges to edit this file.

 Example /etc/environment File

PATH="/usr/local/cuda/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
LD_LIBRARY_PATH="/usr/local/cuda/lib64/"
