SDK Installation

Jetpack mainly includes system images, libraries, APIs, developer tools, examples, and some documentation.
The SDK includes TensorRT, cuDNN, CUDA, Multimedia API, Computer Vision, and Developer Tools.

  • TensorRT : High-performance deep learning inference runs for image classification, segmentation, and object detection neural networks, which speeds up deep learning inference and reduces the runtime memory footprint of convolutional and deconvolutional neural networks.
  • cuDNN: The CUDA deep neural network library provides high-performance primitives for deep learning frameworks, including support for convolution, activation functions, and tensor transforms.
  • CUDA : The 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 application performance.
  • Multimedia API: The Jetson Multimedia API provides a low-level API for flexible application development.
  • Computer Vision: VPI (Vision Programming Interface) is a software library that provides computer vision/image processing algorithms implemented on PVA1 (Programmable Vision Accelerator), GPUs, and CPUs, where OpenCV, the leading open source library for computer vision, image processing, and machine learning, now features GPU acceleration for real-time operation, where VisionWorks2 is a software development kit for computer vision (CV) and image processing.
  • Developer Tools: Developer Tools 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 application performance.

These are some of the features of the SDK.

Install SDK with Commands

When using SDK Manager to install SDK, there is no need to set nano to recovery mode, which means there is no need to short the pins.

  • Powering up the Nano normally.
  • After the Jetson Nano enters the system and boots normally, use the USB cable to connect the Jetson Nano's Micro USB port to the Ubuntu host computer.
  • Run the sdkmanager command on the Ubuntu host computer to open SDK Manager (SDK Manager needs to be installed first).
  • Similar to the previous operation of programming the system, the difference is: not to check the OS option, check the SDK option, and then continue to the installation.
  • After downloading the resources, you will be prompted to fill in the username and password, just fill in the username and password of the nano system.
  • Wait for the SDK to be installed successfully.
sudo apt update
sudo apt install nvidia-jetpack
