Excerpts from the Introduction:

This book tries to cover a range of hardware and aspects of ARMLinux. It assumes that you are at least a competent computer user, more likely an experienced developer, but perhaps not very familiar with GNU/Linux or the ARM and its development platforms.

There are many things that are specific to different items of hardware, and many things that are common across various devices. We have tried to avoid too much repetition, but we have also tried to make the text reasonably linear in the hardware chapters. This is inevitably a compromise. In general you should find that reading through the relevant hardware chapter will get you going, but will not go into much depth about why you are doing things and what other options there might be at each stage. We refer to other chapters that have more details on each aspect (using JFlash, patching the kernel, etc) throughout these texts. If you have feedback on the book we'd be very happy to have it, so as to improve future versions - see Chapter 13.

In a fast-moving field like this, this book will always be a work-in-progress. We give the current state of the art at the time of writing, but recognise that this will soon change. Thus we try to provide links to the places online where you can get the latest info. When you find things that are out of date, of just plain wrong, please tell us.

There will be future editions covering more devices and more subject areas. Things that will definately be in the next release are coverage of porting the kernel to a new ARM device, more information for developers using a Windows host PC rather than a Linux one, and more on debugging and simulation techniques.
