Jetson TK1

About this site
This is NVIDIA's official Embedded Tegra & Jetson TK1 Wiki. Most of these pages are an open community Wiki, so in other words, NVIDIA maintains this Wiki regularly but even you can modify this Wiki!

NVIDIA's other official embedded Tegra community sites:
 * The official forum for discussing embedded Tegra & Jetson TK1 issues with the community & NVIDIA.
 * The official blog to stay updated with the latest news & plans for embedded Tegra & Jetson TK1 from NVIDIA. The blog on Google+ is also linked to from Twitter and LinkedIn. Or if you want to be emailed with these anouncements then send an email to TODO.

About Tegra K1
Tegra K1 is the world's first chip to have the same advanced features & architecture as a modern desktop GPU while still using the low power draw of a mobile chip! The Jetson TK1 board therefore allows embedded devices to use the exact same CUDA code that would also run on a desktop GPU (used by over 100,000 developers), with similar levels of GPU-accelerated performance as a desktop!

About Jetson TK1
Jetson TK1 is NVIDIA's embedded Linux development platform featuring a Tegra K1 SOC (CPU+GPU+ISP in a single chip), selling for $192 USD ($1 per CUDA core!). Jetson TK1 comes pre-installed with Linux4Tegra OS (basically Ubuntu 14.04 with pre-configured drivers). There is also some official support for running other distributions using the mainline kernel, discussed further in the Distributions and Mainline kernel sections below.

Besides the quad-core 2.3GHz ARM Cortex-A15 CPU and the revolutionary Tegra K1 GPU, the Jetson TK1 board includes similar features as a Raspberry Pi but also some PC-oriented features such as SATA, mini-PCIe and a fan to allow continuous operation under heavy workloads:

 * SD/MMC card: a full-size slot
 * USB 3.0: a full-size Type-A female socket
 * USB 2.0: a micro-AB socket (a micro-B to female Type-A adapter is included to use this as a second full-size USB port)
 * HDMI: a full-size port
 * RS232: a full-size DB9 serial port
 * Audio: a ALC5639 Realtek HD Audio codec with Mic in and Line out jacks
 * Ethernet: a RTL8111GS Realtek 10/100/1000Base-T Gigabit LAN port
 * SATA: a full-size port that supports 2.5" and 3.5" disks, but is not hot-pluggable. (Turn off the power before plugging in disk drives)
 * JTAG: a 2x10-pin port for debugging
 * Power: a 12V DC barrel power jack, plus a 4-pin PC IDE power connector
 * Fan: a 12V 1.3W fan-heatsink (to allow running long durations inside an enclosure)

The following signals are available through the 125-pin expansion port:
 * Camera ports: 2 fast CSI camera ports (one 4-lane and one 1-lane)
 * LCD port: LVDS / eDP Display Panel
 * Touchscreen ports: Touch SPI 1x4 + 1x1 CSI-2
 * UART
 * HSIC
 * I2C: 3 ports
 * GPIO: 7 x GPIO pins (1.8V). Camera CSI pins can be used for extra GPIO if you don't use both cameras.

Hardware-acceleration APIs supported:
 * CUDA 6.0 (SM3.2, roughly the same as desktop SM3.5)
 * OpenGL 4.4
 * OpenGL ES 3.1
 * NPP
 * OpenCV4Tegra (NEON & GLSL & quad-core optimizations)
 * VisionWorks

Buying Guide
Where can I get one and for how much?
 * Jetson TK1 became publicly available from TODO, and is currently available at the NVIDIA store, and also within USA at Newegg and Micro Center and Europe at Zotac.
 * Jetson TK1 costs $192 USD (ie: $1 per CUDA core!).
 * It includes a power supply (with a detachable US mains cord), a USB micro-B cable for connecting it to a PC, and a USB micro-B to female USB-A adapter allowing you to have 2 regular USB ports.

Basic Setup
Whether you want to sew your embedded Tegra into a backpack or put it in a robot or simply use it as an ultra powerful media center, the first thing you should do is attach it to a monitor & keyboard & mouse to make sure it works and get familiar with it for a few minutes. The Jetson TK1 Quick Start Guide (included as a booklet with your Jetson TK1) shows how to do this. Basically, you plug in a HDMI monitor or TV, plug a keyboard into the USB3.0 port, plug a mouse into the included micro-B to female USB adapter and plug that into the micro-B USB2.0 port on the board. Then plug the 12V power supply in, press the small POWER button, then watch it boot up into Linux4Tegra (that is basically Ubuntu 14.04 with some drivers pre-configured).

If you plug in an Ethernet cable into the LAN port (or plug in a USB Wifi dongle), you can already start using it as a mini PC with powerful GPU acceleration!

If you want to access your device remotely from your PC (eg: you don't want to unplug yout monitor & keyboard & mouse from your PC or you only have a laptop), you can follow the Remote Access page to view the device's output from your PC and control it from the keyboard & mouse on your PC.

Tutorials for developing with Jetson TK1
The following are tutorial projects for hardware and/or software development. Since Jetson TK1 is many times faster than the other dev boards, it allows more complex projects than what other dev boards could be used for, so some of these tutorials may be quite long. Anyway, just like most of this embedded Tegra wiki, it is maintained regularly by NVIDIA but anyone can create or edit tutorials too, so if you have something useful to share below about Jetson TK1 or Tegra then please do so :-)

Linux distributions running on Tegra
Jetson TK1 comes preloaded with NVIDIA's Linux4Tegra (L4T) distribution. However it is possible to install other distributions on a Tegra device:


 * /Linux4Tegra/ (L4T) distribution: basically Ubuntu 14.04 with pre-configured drivers for bootloader, kernel, OpenGL, X.Org, Multimedia, etc.
 * others?

Upstream/mainline OS & kernel system software on Tegra
NVIDIA's Tegra SoCs are well supported by mainline OSS such as Linux and U-Boot. This section contains an index of topics related to running mainline software on Tegra.


 * /Mainline SW/U-Boot/.
 * /Mainline SW/Linux kernel/.

Other embedded Tegra boards created by NVIDIA
Jetson TK1 was the first embedded board that NVIDIA created for the general public, but there have also been some other Tegra Boards, including the production-grade VCM + Jetson Pro prototyping playform for the automotive industry.

Other SOCs created by NVIDIA
/SoCs/: NVIDIA made several previous generations of Tegra SOCs for the mobile, automotive and MP3 player industries.
