RealView Compilation Tools Developer Guide: 3.1. About embedded software development

3.1. About embedded software development

Most embedded applications are initially developed in a prototype environment with resources that differ from those available in the final product. Therefore, it is important to consider the processes involved in moving an embedded application from one that relies on the facilities of the development or debugging environment to a system that runs standalone on target hardware.

When developing embedded software using RealView Compilation Tools, you must consider the following:

Understand the default compilation tool behavior so that you appreciate the steps necessary to move from a default build to a fully standalone application.
Some C library functionality executes by using debug environment resources. If used, you must re-implement this functionality to make use of target hardware.
RealView Compilation Tools has no inherent knowledge of the memory map of any given target. You must tailor the image memory map to the memory layout of the target hardware.
An embedded application must perform some initialization before the main application can be run. A complete initialization sequence requires code that you implement in addition to RealView Compilation Tools C library initialization routines.
