CHAPTER Meet the beagles 2 INFORMATIONINTHISCHAPTER: • Open hardware • BeagleBoard-xM—open hardware desktop replacement • BeagleBone—for when microcontrollers are not powerful enough • BeagleBone Black—best of both worlds INTRODUCTION Imagine using a device that you find indispensable, something that you might use every day. Now, imagine that you have come up with an improvement. Most of the devices that you use are protected by patents and copyrights. Furthermore, in the United States, it is potentially illegal to figure out how something works, a process known as reverse engineering. Many companies insert anti-reverse engineering clauses in their end-user license agreements (EULA) in order to discourage reverse engineering of their products. Concerned about legal issues, you forget about your innovation and life goes on with a device that is okay, but could be better. There are some in the world, this author included, that find this scenario unacceptable. Imagine a better world in which you can find out everything you wish to know about any device, a place where designs are fully documented and can be freely used to improve or modify a device, and a land in which a design could even be completely embedded inside a new design without fear of lawsuits. You have just entered the world of open hardware (sometimes known as open-source hardware). Open hardware allows society as a whole to advance at a quicker pace. There are open prototyping platforms such as the Arduino (http://arduino.cc), open 3-D printers (i.e., http://reprap.org), and even open satellites. Making a hardware design open increases the number of people who might come up with improvements. While it may seem counterintuitive, companies designing and manufacturing open hardware can be profitable. One need only look at the Arduino project with its scores of projects and strong community support to see what a successful open hardware project can look like. Open hardware designs can showcase the capabilities of various hardware components. Hacking and Penetration Testing with Low Power Devices © 2015 Elsevier Inc. All rights reserved. 13
14 CHAPTER 2 Meet the beagles TEXAS INSTRUMENTS DEVICES In part to showcase some of their chips and to encourage their use, Texas Instruments (TI) allows some employees to develop and promote open hardware computer boards featuring TI products (see http://beagleboard.org/about for more details). These boards are developed by a US-based nonprofit corporation known as the Beagle- Board.org Foundation. At the time of this writing, two TI employees are devoting considerable effort to the BeagleBoard.org Foundation. Jason Kridner serves as community manager and Gerald Coley is responsible for hardware design. BEAGLEBOARD-xM The very first board developed by BeagleBoard.org is known as the BeagleBoard. The BeagleBoard was released in July 2008 and is still available today. Based on the 720 MHz TI OMAP3530 Cortex-A8 processor, this board features 256 MB RAM, 256 MB flash memory, HDMI video, S-Video, USB On-The-Go port, USB host port, SD card slot, RS-232 port, and stereo audio. The list price for this 75 mm by 75 mm board is $125. An updated board known as the BeagleBoard-xM was released in September 2010. The BeagleBoard-xM is billed as a $149 desktop replacement (Figure 2.1). I will summarize some of its features here using the BeagleBoard-xM System Reference Manual, which is available at http://circuitco.com/support/index.php? title¼BeagleBoard-xM#Rev_C2. Texas Instruments bills the 1 GHz DM3730 processor found in the BeagleBoardxM as a digital media processor (see http://www.ti.com/product/dm3730 for full details). This processor features a NEON SIMD coprocessor, which can significantly speed up multimedia applications and mathematical calculations (http://www.arm. com/products/processors/technologies/neon.php). This processor utilizes a package on package (POP) design. The 512 MB RAM chip is installed on top of this chip. This processor is more than sufficient to run a full-featured Linux and standard penetration testing tools. The BeagleBoard-xM is pictured in Figures 2.2 and 2.3. FIGURE 2.1 Major differences between the BeagleBoard and BeagleBoard-xM.
