Embedded Linux Tutorial Pdf

Today, the use of Linux in embedded systems is no laughing matter. Indeed, many .. Though each chapter is based on a different architecture, the commands. A tutorial on Basics of Embedded Linux, how embedded linux works. Know more about Embedded Linux, its installation, hardware and firmware, boot loader. Use embedded Linux file systems, including JFFSwith detailed guidelines for building Flash .. This book is not a detailed hardware tutorial.

There's a great deal of excitement surrounding the use of Linux in embedded systems - for everything from cell phones to car ABS systems and water-filtration plants - but not a lot of practical information. Building Embedded Linux Systems offers an in-depth, hard-core guide to putting together embedded systems based on Linux. Updated for the latest version of the Linux kernel, this new edition gives you the basics of building embedded Linux systems, along with the configuration, setup, and use of more than 40 different open source and free software packages in common use. The book also looks at the strengths and weaknesses of using Linux in an embedded system, plus a discussion of licensing issues, and an introduction to real-time, with a discussion of real-time options for Linux. This indispensable book features arcane and previously undocumented procedures for: Building your own GNU development toolchain Using an efficient embedded development framework Selecting, configuring, building, and installing a target-specific kernel Creating a complete target root filesystem Setting up, manipulating, and using solid-state storage devices Installing and configuring a bootloader for the target Cross-compiling a slew of utilities and packages Debugging your embedded system using a plethora of tools and techniques Using the uClibc, BusyBox, U-Boot, OpenSSH, thttpd, tftp, strace, and gdb packages By presenting how to build the operating system components from pristine sources and how to find more documentation or help, Building Embedded Linux Systems greatly simplifies the task of keeping complete control over your embedded operating system.

To put it simply — the operating system manages the communication between your software and your hardware. The OS is comprised of a number of pieces: The Bootloader: The software that manages the boot process of your computer.

For most users, this will simply be a splash screen that pops up and eventually goes away to boot into the operating system. The kernel is the core of the system and manages the CPU, memory, and peripheral devices.

Daemons: These are background services printing, sound, scheduling, etc that either start up during boot, or after you log into the desktop. This is the shell — a command process that allows you to control the computer via commands typed into a text interface. This is what, at one time, scared people away from Linux the most assuming they had to learn a seemingly archaic command line structure to make Linux work.

This is no longer the case. With modern desktop Linux, there is no need to ever touch the command line.

Graphical Server: This is the sub-system that displays the graphics on your monitor. Desktop Environment: This is the piece of the puzzle that the users actually interact with.

Each desktop environment includes built-in applications such as file managers, configuration tools, web browsers, games, etc. Applications: Desktop environments do not offer the full array of apps. Just like Windows and Mac, Linux offers thousands upon thousands of high-quality software titles that can be easily found and installed. Most modern Linux distributions more on this in a moment include App Store-like tools that centralize and simplify application installation.

For example: Ubuntu Linux has the Ubuntu Software Center Figure 1 which allows you to quickly search among the thousands of apps and install them from one centralized location. The Ubuntu software center is a Linux app store that carries thousands of free and commerical applications for Linux. Why use Linux?

This is the one question that most people ask. Why bother learning a completely different computing environment, when the operating system that ships with most desktops, laptops, and servers works just fine? To answer that question, I would pose another question.

Or are you constantly battling viruses, malware, slow downs, crashes, costly repairs, and licensing fees? WhyARM hardware is widely used? The term OS porting means to modify or customize an OS, which is running on particular hardware architecture, in such a way that it can run on another particular kind of architecture when loaded into one.

We can find Linux OS normally in personal computers. The Linux supporting personal computer mostly use Intel processors, and the architecture of Intel based processors are x86 or x But as we mentioned before, most of the embedded devices use ARM based processors. So if we required loading the Linux OS into an embedded device, we must do something that will enable the OS running on x86 based hardware to run on ARM based hardware, and we call it Linux Porting.

Simply, loading and running the Linux from one processor to another processor of different architecture type. Linux porting is a wide topic itself, and is the most important step in developing an embedded Linux system.

It is also the most difficult step as well.

I will try to explain the basics of Linux porting briefly. Necessary things to be taken care of while Linux porting 3. Linux support wide variety of hardware architectures, including ARM architecture.

It is the first code that execute when the device is powered up. Normally the firmware is just a simple initialization and bootloader routine.
