JetPack 3.2.1 Release Notes

NVIDIA JetPack SDK is the most comprehensive solution for building AI applications. Use the JetPack installer to flash your Jetson Developer Kit with the latest OS image, to install developer tools for both the host PC and Developer Kit, and to install the libraries and APIs, samples, and documentation needed to jumpstart your development environment.

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

Note: An Ubuntu host PC is required to run the JetPack installer. It can flash and update software on a target Jetson device, but it cannot not run directly on that device. When no target device is present, the JetPack installer can still be used to update software on the host PC.


3.2.1

JetPack 3.2.1 includes support for the latest L4T BSP software packages for the Jetson TX2, Jetson TX2i, and Jetson TX1 Developer Kits. Automatically flash your Jetson Developer Kit with the latest BSPs (L4T 28.2.1 for Jetson TX2 and TX2i and L4T 28.2 for Jetson TX1) and install the latest software tools required to build and profile for applications for the Jetson Platform. This package contains CUDA toolkit for the host (Ubuntu) and target platform, the latest NVIDIA Developer Tools (Tegra Graphics Debugger 2.5 and NVIDIA System Profiler 4.0), VisionWorks 1.6, cuDNN v7.0.5, Multimedia API v28.2, OpenCV 3.3.1, and TensorRT 3.0 GA.

Please follow the available guide to Download and Install JetPack. We encourage all users to report feedback, bugs and suggestions to improve the workflow experience of future versions of JetPack. A feedback form is available here.

System Requirements

Host Platform Requirements: 

  • JetPack L4T 3.2.1 supports Ubuntu Linux x64 v16.04 on your host PC.
    • Linux Ubuntu 14.04 on your host PC will also work, except OpenCV and VisionWorks will be unavailable for installation on the host PC
    • A valid Internet connection and at least 10GB of disk space is needed for the complete installation of JetPack.

Target Platform Requirements:

  • A Jetson Developer Kit with Jetson TX2, Jetson TX2i, or Jetson TX1 module
  • Additional target requirements:
    • 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 connecting 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.
