Summary

In this chapter, we saw the different media that can be used in embedded systems and the tools we need to approach them, extract them, understand their structures, and modify them. Since the ways to store data are very variable from one system to another, it is not possible to go through every possible variation but, after reading this chapter, you will know (at least partially) the possible tools that you can use, how things are generally organized, and some concepts you could think about when reverse-engineering storage schemes. These tools are very powerful but, like any tool, are limited by the skill of the person that uses them. That's why you should practice and read the documentation of the tools as much as possible.

In the next chapter, we will look into how to modify the stored elements and, from the changes in the system behavior, better understand the structure of the stored data.
