11.1 Introduction

A bootloader is a program that transfers a code (program and/or data) from one memory location to another. The code which is transferred is called boot code. The bootloader and the boot code are indispensable in any microprocessor‐based system. When a microprocessor, which is connected to some peripherals, is powered up, it will not function properly since these peripherals need to be configured and the application, which may reside in non‐volatile memory, should be transferred in the internal ...
