    Question How are crashes decoded on procesors?

    Hey guys, I've been working with airbags modules reset for a while now, and as some of you know, there are softwares that make that cleaning job, but it's interesting to understand what is going on when they do so.

    When we talk about EEPROMs, it's ok. Once the crashed file is clear and you compare both, you can easily see where the crash was and which addresses should be changed once you work with the same module in the future. Although, when we're working with processors such as infineon; SPC; MPC and R7F7, those addresses almost aways change and I can see no pattern between crashes on the same module reference.

    So I was wondering: How do they clean those? Which pattern is followed? I'd like to learn more about the math behind it
    And sometimes the same module has completely different files and still is recognized as valid to the program.

    I tried in every way to solve this matter. I even found a way to put a .bin file on a disassembler to see if there was something I could analise better, but is needless to say that it lead me to nowhere.

    Does anyone have any ideas of how it is done?

    Thanks in advance, folks
