Introduction
The NVIDIA® TX1 Developer Kit is a full-featured development platform for visual computing. It is ideal
for applications requiring high computational performance in a low power envelope. The TX1 Developer
kit is designed to get you up and running quickly: It comes pre-flashed with a Linux environment,
includes support for many common APIs, and is supported by NVIDIAs complete development tool chain.
The board exposes many standard hardware interfaces, enabling a highly flexible and extensible
platform.
Go to http://developer.nvidia.com/embedded-computing for access to software updates and the
developer SDK supporting the OS image and host development platform that you want to use. The SDK
includes an OS image that you will load onto your device, developer tools, supporting documentation,
and code samples to help you get started.
Getting Started
Individual development efforts will vary and may result in modifications to the system configuration. It
is recommended that you begin with the basic system configuration (as shipped) to ensure proper
system operation prior to any further development.
Assumptions
>You have a Tegra Developer System, equipped with the NVIDIA®Tegra®TX1 processor.
>Your developer system should be cabled as follows:
Serial cable plugged into the serial port on the target connected to your Linux host directly
or through a serial-to-USB converter. (To setup serial console on the Linux host.)
(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 should be connected to
the working USB port on the system.
An HDMI cable plugged into the target which is connected to an external HDMI display.
An Ethernet cable plugged into the on board Ethernet port.
Powering Up the Tegra Device
1. Connect a USB keyboard to the USB Type A connector of your device.
2. Connect an HDMI-compatible display to the HDMI connector on your device.
3. Connect the AC adapter supplied in your kit to the power connector of your device. Use the
supplied AC adapter since it is appropriately rated for your kit.
4. Plug the power adapter into an appropriately rated electrical outlet.
5. They system should power on. If not, press and release the power button on the device.

Force Recovery Mode
To update your system, you will need to be in Force USB Recovery Mode so you can transfer system
software to the developer board. When in Force USB Recovery Mode, you are able to update system
software and write the boot loader, boot configuration table (BCT), and partition configuration to the
Tegra device.
See the Developer SDK documentation for OS specific instructions when updating system software on
your developer board.
To place system in Force USB Recovery Mode:
1. Power down the device. If connected, remove the AC adapter from the device. The
device MUST be powered OFF, not in a suspend or sleep state.
2. Connect the Micro-B plug on the USB cable to the Recovery (USB Micro-B) Port on the
device [4] and the other end to an available USB port on the host PC.
3. Connect the power adapter to the device.
4. With the system powered on, press and release the POWER button, if necessary; press
and hold the RECOVERY FORCE button; while depressing the RECOVERY FORCE button,
press and release the RESET button; wait two seconds and release the RECOVERY
FORCE button.

Flashing the Boot Loader and Kernel
This section describes the steps required to flash and boot the target Tegra device. It also
provides usage information for the flash.sh helper script.
Flash Procedure
First, flash the board with the boot loader and kernel, and, optionally, flash the rootfs to
internal eMMC.
Prerequisites
The following directories must be present:
•/bootloader—boot loader plus flashing tools (NvFlash, CFG, BCTs, etc.)
•/kernel—a kernel zImage /vmlinux.uimg, DTB files, and kernel modules
•/rootfs—the root file system that you download (This directory starts empty and you
populate it with the sample file system.)
•/nv_tegra—NVIDIA®Tegra®user space binaries and sample applications
You must also have the USB cable connected to the recovery port prior to running the
commands listed in the procedure. For more information, see the Requirements topic in
this section.
To flash the boot loader and kernel
1. Put the target board into reset/recovery mode. Do so by first powering on the board
and then holding the recovery button, and then pressing the reset button as
described in the Quick Start Guide for the board.
2. Run the flash.sh script that is in the top level directory of this release. The script
must be supplied with the target board (jetson-TX1) for the root file system:
$ sudo ./flash.sh <platform> <rootdev>
•If the root file system will be on a USB disk, execute the script as follows:
$ sudo ./flash.sh <platform> sda1
Note: If a SATA device is connected, that device enumerates as sda1.
•If the root file system will be on an SD card, execute the script as follows:
$ sudo ./flash.sh <platform> mmcblk1p1
•If the root file system will be on the internal eMMC, execute the script as follows:
$ sudo ./flash.sh <platform> mmcblk0p1
Where <platform>is jetson-TX1.
The above examples are for u-boot. For fastboot, add the following argument:

Jetson TX1 Developer Kit
User Guide
Jetson | Copyright © 2014 NVIDIA Corporation. All rights reserved. Page 6 of 27
-L <PATH_TO_FASTBOOT_BIN_FILE>
The boot loader and kernel will load.
For more information on U-Boot, see the U-Boot Guide chapter of this document.
Flash Script Usage
You can find the most up-to-date usage information by running flash.sh –h (using the
flash.sh script included in the release). The basic usage information is as follows.

sudo ./flash.sh [options] <platform> <rootdev>
Where you specify the required parameters and one or more of the options shown in the
