Chapter 12: Prototyping with Breakout Boards

Custom board bring-up is what embedded Linux engineers are called on to do time and time again. A consumer electronics manufacturer wants to build a new device and, more often than not, that device needs to run Linux. The process of assembling the Linux image typically starts before the hardware is ready, and is done using prototypes that are wired together from development and breakout boards.
