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 host PC and Developer Kit, and to install the libraries and APIs, samples, and documentation needed to jumpstart your development environment.

JetPack 3.2.1 with the latest BSPs (L4T 28.2.1 for Jetson TX2/TX2i and L4T 28.2 for Jetson TX1) is the latest production software release for NVIDIA Jetson TX2, Jetson TX2i, and Jetson TX1. It bundles all the Jetson platform software, including TensorRT, cuDNN, CUDA Toolkit, VisionWorks, GStreamer, and OpenCV, all built on top of L4T with LTS Linux kernel.

Highlights include support for TensorFlow models, up to 15% perf/W improvement for DL applications, out-of-the-box kernel support for Docker, and support for Ubuntu 16.04 on your host PC.

Key Features in JetPack

TensorRT 3.0 GA TensorRT is a high performance deep learning inference runtime for image classification, segmentation, and object detection neural networks. It speeds up deep learning inference as well as reducing the runtime memory footprint for convolutional and deconv neural networks.
cuDNN 7.0.5 CUDA Deep Neural Network library provides high-performance primitives for all deep learning frameworks. It includes support for convolutions, activation functions and tensor transformations.
VisionWorks 1.6 VisionWorks is a software development package for Computer Vision (CV) and image processing. It Includes VPI (Vision Programming Interface), a set of optimized CV primitives for use by CUDA developers. The NVX library enables direct access to VPI, and the OVX library enables indirect access to VPI via OpenVX framework.
CUDA 9.0

CUDA Toolkit provides a comprehensive development environment for C and C++ developers building GPU-accelerated applications. The toolkit includes a compiler for NVIDIA GPUs, math libraries, and tools for debugging and optimizing the performance of your applications.

Multimedia API

The Jetson Multimedia API package provides low level APIs for flexible application development.

Camera application API: libargus offers a low-level frame-synchronous API for camera applications, with per frame camera parameter control, multiple (including synchronized) camera support, and EGL stream outputs. RAW output CSI cameras needing ISP can be used with either libargus or GStreamer plugin. In either case, the V4L2 media-controller sensor driver API is used.

Sensor driver API: V4L2 API enables video decode, encode, format conversion and scaling functionality. V4L2 for encode opens up many features like bit rate control, quality presets, low latency encode, temporal tradeoff, motion vector maps, and more.

L4T

The NVIDIA® Tegra® Linux Driver Package supports development on the Jetson Platform.
