This is the book you need if you are programming for Single Board Computers (SBCs) that run Linux, or if you do any coding in C that interacts with the hardware. As there isn’t a good name for this body of knowledge, it isn’t easy to find a single source for it. In this book author Harry Fairhead gathers together all of these low-level, hardware-oriented and often hardware-specific ideas.

This is a moderately advanced book. This is not to say that it is difficult, but it does presuppose that you already know how to program in C and that you know the basic idioms of C.
