Introduction
This manual describes the basic, initial setup of an NVIDIA Tegra 250 developer kit (devkit),
and is designed to assist a new user in understanding the hardware, selecting an operating
system to install to the devkit, and connect and configure the hardware to boot that operating
system. Very little operating system-specific information will be found in this manual, as each
operating system supported by the Tegra 250 devkit includes its own support pack with
software and documentation. This manual covers the details that tend to cross over all
supported operating systems.
What is “The Devkit”?
The NVIDIA Tegra 250-based devkit is a compact, Smartbook-motherboard form factor
computer-on-a-board with the following specifications:
- Dual ARM Cortex A9 CPU @1GHz
- 1GB of RAM
- High-performance, shader-based 3D acceleration
- HD video encode and decode
- 512MB of Flash memory
- Onboard wired Ethernet
- WiFi
- Bluetooth
- Analog stereo audio in/out
- USB keyboard/mouse/storage support
- HDMI/DVI-D and VGA/CRT display support
- Onboard SD(HC) slot

Getting Started: Overview
There are a few basic steps required to begin developing for the devkit:
Unboxing:
1) Unpack the devkit components
2) Familiarize yourself with the components
Host PC Configuration:
1) Select your desired devkit operating system
2) Download the support pack for that operating system from the NVIDIA Tegra
developers website
3) Read the documentation provided with that support pack and install it to the
appropriate host PC
4) Download and install any host PC support SW as required by the platform support
pack’s documentation
Connecting the Devkit HW:
1) Locate/procure the required hardware accessories for the devkit (somewhat dependent
upon the selected devkit operating system image)
2) Select the desired video output based on your available display devices and the
operating system image
Installing the Operating System to the Devkit:
1) Follow the operating system image installation instructions provided with the support
pack
2) Boot the devkit

The devkit is the property of NVIDIA Corporation and must be returned to NVIDIA upon completion of use. The devkit is not FCCapproved and may not be sold or leased.
Also, the devkit is intended to be used only by technically skilled professionals engaged in the creation of hardware and software
based on the technology demonstrated in the kit. As a device subject to professional installation, the installer is responsible for
ensuring that any antenna connected to the device will not result in emissions that exceed the limits in part 15 of the FCC Rules.
Unboxing
Devkit Contents and Hardware Requirements
As shipped, your devkit should contain the following items:
• Devkit main board (rectangular circuit board containing the Tegra chip and connectors
for networking, USB peripherals, storage and display devices)
• 15V power adapter (USA 120V mains power connection)
• Adjustable, folding, threaded WiFi antenna
• Expansion board (smaller, square circuit board containing a serial port, LEDs and a few
buttons)
Also required to use the devkit, but not supplied (developer must provide these):
• Host PC with USB ports. The exact OS that this host PC must be running may differ
depending upon the devkit OS to be used, but is most frequently Microsoft Windows.
• USB mini (NOT micro, as with previous Tegra devkits) to USB cable (for device setup
and connectivity)
• External display supporting VGA (15-pin D-Sub), HDMI or DVI (via HDMI-to-DVI
adapter)
• SD card or USB-based “thumb drive” for additional storage
• USB mouse
• USB keyboard
Strongly recommended to use the devkit, but not supplied (developer should provide these):
• Powered USB hub

The annotated items include:
January 2010 - 6 -
• 15V Power jack. Supplies the main power to the devkit (the devkit as shipped to
developers does not directly support battery power)
• VGA (CRT) jack. Support for 15-pin D-Sub analog display output
• HDMI jack. Support for digital display output
• WiFi antenna jack. Connection point for supplied (or 3rd-party) WiFi antenna
• Tegra 250 chip. The heart and soul of the Tegra 250 devkit
• USB-A jacks (3). Support for common peripherals (use of a powered USB hub is
strongly recommended)
• Expansion board connectors. “Header” connections for an expansion board (supplied)
that adds status LEDs, copies of the power, reset and recovery buttons, and a serial port.
• “ACOK” configuration switch. A configuration micro-switch that is used to adjust the
power behavior of the devkit. In the left (BATT) position, the AC adapter simulates a
battery, and the soft power button functions normally. In the right (NORM) position,
applying power causes the device to turn on, without pressing the power button. The
left (BATT) position is preferred for developers.
• Power button. Pressing this switch will toggle the power to the device on and off
• Recovery (flashing) button. Used to place the devkit in a special mode that leaves it
ready to receive a new operating system image via USB (“recovery” mode)
• Reset button. Soft reset
• Microphone jack. Stereo microphone input as a 1/8” phone jack
• Headphone jack. Stereo headphone output as a 1/8” phone jack
• Ethernet jack. Wired networking if supported by the OS
• SD card slot. Supports normal and high-capacity SD card storage
• USB-mini jack. USB jack for flashing the device (updating OS images) and connecting
the device to a host PC.
