System Requirements

Supported Host Platform Requirements: 

  • Ubuntu Linux x64 (v14.04)

    JetPack for L4T runs on the host Ubuntu x86_64 machine and sets up your development environment and Jetson Development Kit target via remote access. Note: A valid Internet connection and at least 10GB of disk space is needed for the complete installation of JetPack.

Target Platform Requirements:

  • Jetson Developer Kit (TX1 or TK1 based) 
    • 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 plugged into 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.
