Jetpack 2.3.1 Release Notes

JetPack for L4T (Jetson Development Pack) is an on-demand all-in-one package that bundles and installs all software tools required to develop for the NVIDIA® Jetson Embedded Platform (including flashing your Jetson Development Kit with the latest OS images). JetPack includes host and target development tools, APIs and packages (OS images, tools, APIs, middleware, samples, documentation including compiling samples) to enable developers to jump start their development environment for developing with the Jetson Embedded Platform. The latest release of JetPack runs on an Ubuntu 14.04 Linux 64-bit host system and supports both the latest Jetson TX1 Development Kit and Jetson TK1 Development Kit.

NVIDIA JetPack is offered free of charge, but requires NVIDIA Embedded Developer Program membership. Not a member? Join the Embedded Developer Program here.

System Requirements

Supported Host Platform Requirements: 

  • Ubuntu Linux x64 (v14.04)

    JetPack for L4T runs on the host Ubuntu x86_64 machine and sets up your development environment and Jetson Development Kit target via remote access.
    Note: A valid Internet connection and at least 10GB of disk space is needed for the complete installation of JetPack.

Target Platform Requirements:

  • Jetson Developer Kit (TX1 or TK1 based) 
    • USB Micro-B cable connecting Jetson to your Linux host for flashing.
    • (Not included in the developer kit) To connect USB peripherals such as keyboard, mouse, and [optional] USB/Ethernet adapter (for network connection), a USB hub could be connected to the USB port on the Jetson system.
    • An HDMI cable plugged into the HDMI port on Jetson Developer Kit, which is connected to an external HDMI display.
    • An Ethernet cable plugged into the on-board Ethernet port, which is connected to either a secondary network card on your Linux host or the same network router providing internet access for the Linux host.
