There is a board based on a little-known Taiwanese MK with an ARM Cortex M0 core. What are the chances of dumping the firmware binary?

Question

Electronics

And also reverse-engineer it.
I have reverse engineering experience.
The ability to google, find utilities, try them, if necessary, climb assembler.
A project in Java or C# can be completely decompiled to source.
The datasheet on the MK seems to be there.
The board is mass-produced, used in cheap quadrocopters, it is not intended for anything "such".
It will be necessary to deal with the firmware in such a way as to teach it to "communicate" with another controller, which will completely replace the remote control.
But first, just dump the firmware binary and be able to reload it and make it work.
There may be problems in terms of the fact that it will not be possible to dump, or will not work after reloading the CORRECT firmware, but with changes (or even without a single change)?

Answer 1

why paint a question sheet if there is a controller model? in datasheets in English (Korean?) in white, programming procedures / working with memory are always described, incl. and read protection options.
- Java is exactly what the flight software of quadrocopters is written on. in popularity comes right after php and Lisp.
- many "cheap serial" copters are produced with brains in general in the form of a drop (unframed controller) or even custom microcircuits. if they bother with this, they will obviously not forget the tick of the firmware lock. what kind of reversal can there be?
- I don’t have much up-to-date information, but the source codes on asme are still circulating on the networkwith comments in German for the rc engine controller and are the basis for a bunch of mods. it makes you think about the ease of picking this software.
- the question itself is stupid, or the original task is incorrect. it is cheaper to make something on standard components or just buy a new toy. the alteration will be profitable only if the Chinese also torn the software and there is access to the original source.
