Introduction 31 FIGURE 3.4 Android running on the BeagleBone Black with Chipsee touch screen. Android is based on a Linux kernel. Many commands are shared between Android and Linux as a result. Without further ado, let us move on to discuss the many Linux options available to us when using the BeagleBoard.org devices. A BeagleBone Black with a Chipsee touch screen running Android is shown in Figure 3.4. Linux OPTIONS Not surprisingly, several versions of the Linux, the most popular open-source operating system, are available for the open hardware in the Beagle family. Linux is billed as an operating system by programmers for programmers. Linux has a reputation for extracting the most performance out of hardware, especially when it comes to lowerend or older hardware. That is not to say that it isn’t great for high-end hardware as well. While Windows users have only recently stopped running everything in 32-bit compatibility mode, Linux users have had a 64-bit operating system available to them since 2001. In fact, a 64-bit Linux kernel was available two years before AMD released the first processors based on the AMD64 architecture. You might be surprised to discover how many devices you use secretly run Linux. Many networking devices run Linux. Special versions of Linux (such as OpenWrt) have been created specifically to replace the Linux that ships with a commercial device. Smart televisions and other modern appliances have been known to run Linux. No other operating system can match Linux’s long list of supported platforms. Linux is also a clear winner among hackers. A large number of security tools are available on Linux. Tools that are available on multiple platforms are primarily
32 CHAPTER 3 Installing a base operating system written for Linux first and then ported to other operating systems. The collaborative open-source environment lends itself to the development of necessary security tools, such as full-featured wireless drivers that support monitor mode and packet injection. Linux affords the user many choices. A plethora of shells are available. Users are free to chose from a collection of windowing environments or can forgo a GUI altogether. Multiple programs that perform common tasks, such as editing text files, are available to support users’ preferences. A˚ngstr€om When you hear the word Ångstr€om, you probably think of the unit of measurement (10 10 m). Ångstr€oms are used to describe the wavelength (color) of light and the size of small things such as atoms and molecules. The Ångstr€om Distribution is also an obscure Linux distribution used in embedded systems (http://angstrom-distribu tion.org). The developers of this Linux flavor make a point of saying that it is to be called the Ångstr€om Distribution and not Ångstr€om Linux. The Ångstr€om Distribution’s attributes are summarized in Table 3.1. Ångstr€om has shipped with every BeagleBoard.org device starting with the original BeagleBoard and continuing through the BeagleBone Black (as of this writing, it was just announced that future boards may ship with Debian Linux). This is not surprising given the background of the BeagleBoard designer and what was available for the ARM-based devices in 2008 when the original BeagleBoard debuted. The majority of Linux desktops users are likely unfamiliar with Ångstr€om. While Ångstr€om ships with all the Beagles, we’ll briefly cover the process of building Ångstr€om to give you a better feel for this Linux flavor. Software (including operating systems) for embedded systems is often built on more powerful desktop systems. This process is known as cross compiling (more about this in the next chapter). The biggest reason to do this is that many embedded devices lack the computing horsepower to build software in a reasonable amount of time. Ångstr€om is built using the OpenEmbedded software framework Table 3.1 Ångstr€om Distribution Performance Package manager Desktop application repository support Hacking application repository support Community support Configuration Comments Good—built to optimize the Beagles opkg (similar to dpkg on Debian) Fair Poor—intended for embedded Linux Fair—small community running this distribution Nonstandard tools are used Comes with the Beagles but is likely completely foreign to most users
