The book "Reverse Engineering of Embedded Systems" is a methodology that shows one of the options for researching electronic devices, as well as explaining why the path is exactly what common errors are on this path and how to avoid them. This path is probably not the only one, but it has shown its effectiveness in more than 10 years of practical research on devices. So why not start your steps with him? When the author of this publication began to study devices, all information was collected from senior colleagues, disparate sources, from many experiments, often leading away from the result, from "killed" devices and thoughts about whether this could have been avoided. All this made it possible to form the approach described in this book.
