Embedded Linux is a popular and versatile operating system for embedded devices, such as smartphones, tablets, routers, and IoT products. However, learning embedded Linux can be challenging for beginners who are not familiar with the Linux kernel, drivers, and tools.
That's why the Embedded Linux Primer: A Practical Real-World Approach by Christopher Hallinan is a great resource for anyone who wants to get started with embedded Linux. This book covers the basics of embedded Linux, such as bootloaders, kernel configuration, root filesystems, and cross-compilation. It also provides practical examples and exercises for building and debugging embedded Linux applications on various platforms.
One of the best features of this book is that it comes with a PDF version that you can download for free from the author's website. The PDF version has 12 chapters and over 400 pages of content. It also includes links to online resources and code samples that you can use to follow along with the book.
If you are looking for a comprehensive and hands-on guide to embedded Linux, you should definitely check out the Embedded Linux Primer: A Practical Real-World Approach PDF. It will help you master the skills and concepts needed to develop embedded Linux products in a professional and efficient way.
In this article, we will give you a brief overview of the main topics covered in the Embedded Linux Primer: A Practical Real-World Approach PDF. We will also provide some tips and tricks for getting the most out of this book.
Chapter 1: Introduction to Embedded Linux
This chapter introduces the concept and history of embedded Linux. It explains why embedded Linux is a suitable choice for many embedded applications, and what are the advantages and challenges of using it. It also gives an overview of the embedded Linux development process and the tools involved.
Chapter 2: Basic Development Environment
This chapter guides you through setting up a basic development environment for embedded Linux. It shows you how to install and configure a Linux host system, a cross-compilation toolchain, and an emulator. It also teaches you how to use common tools such as make, gcc, gdb, and strace.
Chapter 3: Working with Embedded Hardware
This chapter covers the basics of working with embedded hardware. It explains how to connect and communicate with your target device, how to use serial ports, USB devices, and network interfaces. It also demonstrates how to use LEDs, buttons, and GPIOs to interact with your device.
Chapter 4: Bootloaders
This chapter dives into the topic of bootloaders. It describes what bootloaders are, what they do, and how they work. It also compares different types of bootloaders, such as U-Boot, Barebox, and GRUB. It shows you how to configure, compile, and install a bootloader on your target device.
Chapter 5: The Linux Kernel
This chapter focuses on the Linux kernel. It explains the architecture and components of the kernel, such as modules, drivers, subsystems, and interfaces. It also shows you how to configure, compile, and install a kernel on your target device.
Chapter 6: Root Filesystems
This chapter deals with root filesystems. It defines what root filesystems are, what they contain, and how they are mounted. It also discusses different types of root filesystems, such as initramfs, NFS, ext4, and SquashFS. It shows you how to create and customize a root filesystem for your target device.
Chapter 7: BusyBox
This chapter introduces BusyBox. It describes what BusyBox is, why it is useful for embedded Linux systems, and how it works. It also shows you how to configure, compile, and install BusyBox on your target device.
Chapter 8: Embedded Networking
This chapter covers embedded networking. It explains how to configure and use network interfaces on your target device, such as Ethernet, Wi-Fi, Bluetooth, and cellular. It also teaches you how to use common network protocols and services on embedded Linux systems, such as TCP/IP, DHCP, DNS, SSH, FTP, HTTP, and MQTT.
Chapter 9: Debugging Embedded Systems
This chapter teaches you how to debug embedded systems. It shows you how to use various debugging tools and techniques on embedded Linux systems,
such as printk(), syslog(), klogd(), dmesg(), /proc/, /sys/, /dev/, lsof(), ps(), top(), gdbserver(), gdbclient(), kgdb(), kdb(), JTAG, aa16f39245
