Preface
Packed with recipes for the Banana Pi, solving the most common real-world problems, viewers get a practical assistance to avoid difficulties.
Full of supportive guides, this book is designed to help you build and expand your device into a versatile box. Any computer enthusiast can quickly learn how to become a Banana Pi expert, while not requiring skills in programming or Linux. Banana Pi Cookbook will allow you to use the technology start from the very beginning, through the daily usage and maintenance, up to setting up a WordPress from scratch, sharing files using Samba or ownCloud, blinking an LED, or playing 1080p videos.
What this book covers
Chapter 1, Installation and Setup, introduces the Banana Pi device. It also explains which distributions are available and how to download and install a Linux distribution. Moreover, we present Android as a contrast to our upcoming Linux adventure.
Chapter 2, Administration, introduces the reader to the most common tools to administrate their fresh Linux installation. We will connect remotely using SSH from Windows (using PuTTY) and Linux (using the command-line SSH application). Besides user modification (adding a new user, changing passwords, and so on), we will also cover basic maintenance tasks, such as searching and installing a new software, updating the system using the distributions package manager, and so on.
Chapter 3, External Disks, covers all about external disk drives. We will connect and mount USB drives and HDD drives using the SATA interface and explore the possibility of switching the root filesystem to and boot from an external drive.
Chapter 4, Networking, presents recipes for common networking tasks using the Banana Pi. One of the key strengths of the device is the fast Ethernet and wireless (Banana Pro) adapters it provides—especially combined with the fast SATA interface—which is the base of powerful network applications.
Chapter 5, Using the GPIO Pins, introduces the GPIO pins. We will light up an LED using the shell. Furthermore, we will build a simple circuit, including a pull-up resistor and control an LED with a button. To achieve this, we will introduce the C programming language with the WiringPi library and the Python scripting language with the RPi.GPIO library.
Chapter 6, Multimedia, covers configuring the two audio outputs (line out and HDMI). We will discuss and solve the hardware acceleration problem by compiling important components and using these mentioned components to build video players and Kodi. The configuration of a remote control using LIRC is also covered.

Chapter 1. Installation and Setup
This chapter will cover the following recipes:
Introduction
The Banana Pi is a single-board computer, which enables you to build your own individual and versatile system. In fact, it is a complete computer, including all the required elements such as a processor, memory, network, and other interfaces, which we are going to explore. It provides enough power to run even relatively complex applications suitably.
In this chapter, we are going to get to know the Banana Pi device. The available distributions are mentioned, as well as how to download and install these distributions. We will also examine Android in contrast to our upcoming Linux adventure.
Thus, you are going to transform your little piece of hardware into a functional, running computer with a working operating system. You will master the whole process of doing the required task from connecting the cables, choosing an operating system, writing the image to an SD card, and successfully booting up and shutting down your device for the first time.
Banana Pi Overview
In the following picture, you see a Banana Pi on the left-hand side and a Banana Pro on the right-hand side:
As you can see, there are some small differences that we need to notice. The Banana Pi provides a dedicated composite video output besides the HDMI output. However, with the Banana Pro, you can connect your display via composite video output using a four-pole composite audio/video cable on the jack.
In contrast to the Banana Pi, which has 26 pin headers, the Banana Pro provides 40 pins. Also the pins for the UART port interface are located below the GPIO headers on the Pi, while they are located besides the network interface on the Pro.
The other two important differences are not clearly visible on the previous picture. The operating system for your device comes in the form of image files that need to be written (burned) to an SD card. The Banana Pi uses normal SD cards while the Banana Pro will only accept Micro SD cards. Moreover, the Banana Pro provides a Wi-Fi interface already on board. Therefore, you are also able to connect the Banana Pro to your wireless network, while the Pi would require an external wireless USB device.
Besides the mentioned differences, the devices are very similar. You will find the following hardware components and interfaces on your device.
On the back side, you will find:
On the front side, you will find:
As you can see, you have a lot of opportunities for letting your device interact with various external components. In the upcoming chapters, we are going to explore most of the possibilities in detail.
Operating systems for the Banana Pi
The Banana Pi is capable of running any operating system that supports the ARM Cortex-A7 architecture. There are several operating systems precompiled, so you are able to write the operating system to an SD card and boot your system flawlessly. Currently, there are the following operating systems provided officially byLeMaker, the manufacturer of the Banana Pi.
Android
Android is a well-known operating system for mobile phones, but it is also runnable on various other devices such as smart watches, cars, and, of course, single-board computers such as the Banana Pi.
The main advantage of running Android on a single-board computer is its convenience. Anybody who uses an Android-based smartphone will recognize the graphical user interface (GUI) and may have less initial hurdles. Also, setting up a media center might be easier to do on Android than on a Linux-based system.
However, there are also a few disadvantages, as you are limited to software that is provided by an Android store such as Google Play. As most apps are optimized for mobile use at the moment, you will not find a lot of usable software for your Banana Pi running Android, except some Games and Multimedia applications. Moreover, you are required to use special Windows software called PhoenixCard to be able to prepare an Android SD card.
Because of the mentioned disadvantages, this book will show you how to get Android up and running, but focus on Linux-based distributions in the next chapters.
Linux
Most of the Linux users never realize that they are actually using Linux when operating their phones, appliances, routers, and many more products, as most of its magic happens in the background. We are going to dig into this adventure to discover its possibilities when running on our Banana Pi device.
The following Linux-based operating systems—so-called distributions—are used by the majority of the Banana Pi user base and are supported officially by the manufacturer:
All of the aforementioned distributions are based on the well-known distribution, Debian. Besides the huge user base, all Debian-based distributions use the same package manager Apt (Advanced Packaging Tool) to search for and install new software, and all are similar to use. In the upcoming recipes, we are going to use Raspbian. However, most recipes will be valid for the other Debian-based distributions.
There are still more distributions that are officially supported by LeMaker, such as Berryboot, LeMedia, OpenSUSE, Fedora, Gentoo, Scratch, ArchLinux, Open MediaVault, and OpenWrt. All of them have their pros and cons or their specific use cases. If you are an experienced Linux user, you may choose your preferred distribution from the mentioned list, as most of the recipes in this book are similar to, or even equally usable on, most of the Linux-based operating systems.
