Do you think that by programming an arduino DUE it is possible to read the AVR assembly program stored inside the chip by connecting the BLUE and ORANGE signals in the connector ?
Do I think that by programming an Arduino Due it is possible to solve the Riemann hypothesis?
Beats the hell outta me.
Understand what you're asking:
- You haven't presented
any evidence about what these pins do. They're named suggestively, but that doesn't mean they are used that way, or are at all times. All *I* see are a couple traces on a PCB. I don't have a clue what you know about this thing so far, and I certainly can't (and, without a budget, won't) figure that out for you.
- I see the pins are wired to a well-known MCU, cool. So what are they doing with them? Are they GPIO sometimes? USART exclusively? What baud? What encoding? Is it binary or ASCII? What is the command set? etc. etc. etc. There are limitless possibilities here.
-
If it is a command interface, can those commands be used to exact desired control over the device? Or to extract firmware, or other hacking-related goals?
-
If not, can those commands be
abused, discovering bugs in the interface? Are there parsing errors, buffer overruns, ACE exploits, etc. possible?
-
If so, can enough bugs be harnessed to develop those hacking-related goals?
In the extreme, the control might be programmed to respond perfectly to the longest possible sequence expressible on the platform, i.e. enumerating a recursive sequence requiring a few kB of state (more if external memory is present, or EEPROM and Flash are used). This will take approximately until the heat death of the universe to explore; good luck!
Or perhaps they've locked it with such a sequence that effectively encodes the solution to an otherwise-currently-unsolved mathematical problem, such as I alluded to above. In which case, we literally
cannot know at present whether such a thing is even provable, let alone in the affirmative.
In short, you're potentially asking for the solution to, if not the entirety of Computer Science as we know it, then at least whatever subset of the field fits within the chip in question -- while having given absolutely nothing to even start from.
I think you should appreciate, now, how unrealistic that question was.
Now, I don't say this to embarrass*. And I don't say this as a dismissal. (If I didn't care about this thread,
I simply wouldn't respond.) I say this, because I see a learning opportunity. I see that something has gone amiss, that has led to a question this far out of proportion. And I see a chance, perhaps, to address the situation. And, I don't know you, I don't know your situation -- maybe this was a hasty question, maybe it was just sent without thinking about it much, a throwaway; maybe you're generally under stress and haven't thought about it clearly, maybe you lack background on these topics and don't understand quite what you're asking -- and I'm not calling out any of these possibilities, it all happens to us at some point or another, there's way more things out there to study than can fit within a single lifetime, and life is full of stresses, whether physical or mental.
*Well, any more than necessary: occasionally, a shock is necessary to rouse the mind, but one must be careful not to overdo it and induce paralysis instead. Maybe I've gone well past that point already... unfortunately, I don't really know.
But such is life. In the process of studying, we can prioritize and select topics useful and important to us. If this be the gap here -- I would just kindly suggest asking about the basics first: what about this thing don't you know, what would be useful to know, and starting from there. It's okay to tell us about where you're coming from, what you know, what you want to do. And it helps us help you: we can better answer questions, when we know what level of complexity to write within. Don't ask about something you (again, perhaps) don't understand -- but absolutely do ask about what you need to know to understand it, build up to it.
Cheers,
Tim
