L4T

NVIDIA L4T provides the Linux kernel, bootloader, NVIDIA drivers, flashing utilities, sample filesystem, and more for the Jetson platform.

You can customize L4T software to fit the needs of your project. By following the platform adaptation and bring-up guidelines, you can optimize your use of the complete Jetson product feature set. Follow the links below for details about the latest software libraries, frameworks and source packages.

*NOTE: For setting up your Jetson Developer Kit, we recommend using the JetPack installer. The JetPack installer provides access to the complete Jetson SDK which includes:

  • L4T Sample Filesystem
  • Tools and Flashing Utilities
  • The latest Libraries, APIs, and Samples for AI, Computer Vision, GPU Compute, and Multimedia

Download the latest version of L4T for Jetson TX2, Jetson TX1, Jetson TK1 as well as other software from the Download Center.

VisionWorks

The NVIDIA VisionWorks toolkit is a software development package for computer vision (CV) and image processing. VisionWorks™ implements and extends the Khronos OpenVX standard, and it is optimized for CUDA-capable GPUs and SOCs enabling developers to realize CV applications on a scalable and flexible platform.

cuDNN

The NVIDIA CUDA Deep Neural Network library (cuDNN) is a GPU-accelerated library of primitives for deep neural networks. Deep learning developers and researchers worldwide rely on the highly optimized routines in cuDNN so they can focus their efforts on designing and training neural network models rather than spending time on low-level performance tuning.

OpenCV4Tegra

This is a version of OpenCV that NVIDIA optimized specifically for the Tegra platform family. It is available for Linux for Tegra, Android, and Vibrante (Embedded Linux) operating systems. It contains Tegra-specific optimizations that enable it to often run several times faster than the OpenCV for Android implementation.
