1. How to Install JetPack

Depending on your Jetson device, there are one or two ways to install JetPack.

1.1. SD Card Image

For NVIDIA Jetson Nano Developer Kit users, the simplest JetPack installation method is to follow the steps at Getting Started with Jetson Nano Developer Kit to download and write an image to your microSD card, then use it to boot the developer kit.

1.2. NVIDIA SDK Manager

NVIDIA SDK Manager supports JetPack installation on these Jetson products:

  • NVIDIA Jetson AGX Xavier on a Jetson AGX Xavier Developer Kit carrier board

  • NVIDIA Jetson Xavier NX module on a Jetson Nano Developer Kit carrier board1

  • NVIDIA Jetson Nano module on a Jetson Nano Developer Kit carrier board

  • NVIDIA Jetson TX2 series modules on a Jetson TX2 Developer Kit carrier board

  • NVIDIA Jetson TX1 on a Jetson TX2 Developer Kit carrier board

A Linux host computer running Ubuntu Linux x64 version 18.04 or 16.04 is required to run SDK Manager. Detailed instructions can be found here:

https://docs.nvidia.com/sdk-manager/index.html

1 The updated Jetson Nano Developer Kit (PN: 945-13450-0000-100) includes a carrier board that is compatible with the Jetson Xavier NX module. The carrier board included in the previous version developer kit (PN: 945-13450-0000-000) is not compatible.

1.3. Package Management Tool

NVIDIA now offers JetPack components as Debian packages.

This enables, for example, installation of all JetPack components via the nvidia-jetpack metapackage. Assuming a Jetson developer kit running L4T 32.3.1 or higher, issuing these commands on the developer kit will result in a full JetPack install:

sudo apt-get update
sudo apt-get install nvidia-jetpack

To view individual Debian packages which are part of nvidia-jetpack metapackage, enter the command:

sudo apt-cache show nvidia-jetpack

Refer to the NVIDIA Jetson Linux Developer Guide for details about L4T specific Debian packages.

2. Upgrading JetPack

Starting with JetPack 4.4, upgrading from previous JetPack versions to the latest JetPack version can be achieved using a package management tool like apt*. Follow the below steps to perform the upgrade:

  1. Upgrade L4T by referring to the OTA section of the NVIDIA Jetson Linux Developer Guide.

  2. Once L4T is upgraded, reinstall the nvidia-jetpack metapackage with the following:

    sudo apt-get install nvidia-jetpack

In case the disk space is limited (for example, if you are using Jetson Nano with 16GB microSD card), follow the below steps to upgrade:

  1. Remove all JetPack compute components (the example shown below is for upgrading from JetPack 4.3).

    sudo apt autoremove --purge nvidia-container-csv-cuda libopencv-python libvisionworks-sfm-dev libvisionworks-dev libvisionworks-samples libnvparsers6 libcudnn7-doc libcudnn7-dev libnvinfer-samples libnvinfer-bin nvidia-container-csv-cudnn libvisionworks-tracking-dev vpi-samples tensorrt libopencv libnvinfer-doc libnvparsers-dev libcudnn7 libnvidia-container0 cuda-toolkit-10-0 nvidia-container-csv-visionworks graphsurgeon-tf libopencv-samples python-libnvinfer-dev libnvinfer-plugin-dev libnvinfer-plugin6 nvidia-container-toolkit libnvinfer-dev libvisionworks libopencv-dev nvidia-l4t-jetson-multimedia-api vpi-dev vpi python3-libnvinfer python3-libnvinfer-dev opencv-licenses nvidia-container-csv-tensorrt libnvinfer6 libnvonnxparsers-dev libnvonnxparsers6 uff-converter-tf nvidia-docker2 libvisionworks-sfm libnvidia-container-tools nvidia-container-runtime python-libnvinfer libvisionworks-tracking
  2. If JetPack was installed using SDK Manager, remove the local repo (the example shown below is for upgrading from JetPack 4.3).

    sudo apt purge cuda-repo-l4t-10-0-local-10.0.326 libvisionworks-repo libvisionworks-sfm-repo libvisionworks-tracking-repo
  3. Run apt-clean.

    sudo apt clean
  4. Upgrade L4T by referring to the OTA section of the NVIDIA Jetson Linux Developer Guide.

  5. Once L4T is upgraded, reinstall the nvidia-jetpack metapackage.

    sudo apt-get install nvidia-jetpack
