Debuggers don’t work well with real-time code. and there is WAY to much code
for that.
Professionally I’ve had to come up to speed on large software projects several
times. The best way is to first become an expert at the user level and learn
what it does. This applies to radars, camera firmware, and everything else.
Then you skim-read the code just to see what is there. and take notes on what
the parts are. Next study one section at a time. You generally don’t need to
know how everything works in great detail, just where to find it if you need it.
Another good way to learn is to write new regression tests, no software ever
has enough of these. Writing a test forces you to look in detail and the test
result proves you understand.
Then, at last, you can make changes, then build and test. But the first step
is to be an expert-level user.
