Minimum system requirements for the host computer are:

• Ubuntu Linux x64 v16.04 or v18.04
• A valid Internet connection
• At least 23GB of disk space

INCLUSO NELLA CONFEZIONE

The Jetson TX2 Developer Kit includes:

• Jetson TX2 module (P3310) with thermal solution
• Reference carrier board (P2597)
• Power supply with AC cord

Note about carrier board revisions
The B02 and B04 revision carrier boards are extremely similar. B04 added the CR5 and CR6 LEDs and some minor circuit changes. The C02 revision included changes in support of Jetson TX2i and Jetson TX2 4GB modules, consolidation of button header pins into a single pin header, and changing the SATA connector to a right angle type to avoid possible conflict with a PCIe card. See the Jetson TX2 Developer Kit Carrier Board Specification for comprehensive information.

COME INSTALLARE JETPACK
Installing JetPack to your developer kit requires you to perform these steps, detailed in the sections below:

1. Download and install NVIDIA SDK Manager on the Linux host computer.
2. Connect your developer kit to the Linux host computer.
3.  Put your developer kit into Force Recovery Mode.
4.  Use SDK Manager to select and install desired components.
5. Download SDK Manager on the Linux Host Computer
   You must have a Linux host computer to run SDK Manager and flash the developer kit. Supported host operating systems are:
6. Ubuntu Linux x64 Version 18.04 or 16.04
7. Seguire queste istruzioni per scaricare e installare NVIDIA SDK Manager.

Nota:
SDK Manager can flash and install software on a target Jetson device, but it cannot run directly on that device. Whether or not a Jetson device is  present, you can use SDK Manager to update software on the Linux host.

Connect Developer Kit to the Linux Host Computer
Prepare your Jetson TX2 Developer Kit for initial setup as follows. For “headless” setup, skip the first two steps.

• Connect an external HDMI display to the carrier board’s HDMI port.
• Connect a USB keyboard and mouse to a USB hub (not included) and connect the hub to the developer kit’s USB Type-A port. (The USB Micro AB port will be needed for flashing.)
• Insert the Micro-B end of the included USB Micro-B to USB A cable to the carrier board’s USB Micro-AB port. Connect the other end to your Linux host computer.
• Connect the included AC adapter to the carrier board’s power jack. Plug the AC adapter into an appropriately rated electrical outlet.
• Use only the supplied AC adapter, as it is appropriately rated for your device.

Put Developer Kit into Force Recovery Mode
The developer kit must be in Force Recovery mode (RCM) to enable the installer to transfer system software to the Jetson module.

1. Connect the developer kit as described above. It must be powered off.
2. Press and hold down the Force Recovery button.
3. Press and hold down the Power button.
4. Release the Power button, then release the Force Recovery button.

Run SDK Manager
NVIDIA SDK Manager enables installation of software to the Jetson module and/or your Linux host computer.
For full instructions, see the SDK Manager documentation.

Nota:
After the Jetson is flashed with the OS, it reboots and prompts you for initial configuration information like keyboard layout, username and password, etc.
If no display is attached to the developer kit during this first boot, the initial configuration will be “headless.” That is, you must communicate with the developer kit through a serial application on the Linux host computer (e.g., puTTY) connected via a host serial port to the correct local serial device.

WORKING WITH L4T

• NVIDIA L4T (the operating system component of Jet Pack) provides the Linux kernel, Bootloader, board support package (BSP), and sample filesystem for Jetson developer kits. SDK Manager can install L4T along with all the other Jet Pack components to get your developer kit up and running quickly.
• L4T is also available for download directly from the main L4T page on the Jetson Developer Site. See the “Quick Start Guide” section of the L4T Development Guide for flashing instructions.
• See also the Platform Adaptation and Bring-Up Guide, which describes how to port the L4T BSP and Bootloader from your developer kit to a new hardware platform incorporating the Jetson module. Porting L4T to a new device enables use of the other JetPack components on that device, along with the software you’ve created using the developer kit.
