I'll admit like others I'm more C biased. This whole debugging story is not very flattering. Tbh my team would not be happy if I told them I didn't 3-4 weeks on something because I used an unsupported language, library, debugger, changed compilers often (did I see him say nightly builds?? On production??), etc etc.

I'm still not sure I understand why he couldn't just diff between versions. And the black box thing seems like a fool's errand. If changing the order of random things makes the issue go away, you can't change anything. The only thing you can do is use the binary you already have. Especially because even if you have 2 not working versions, fixing one doesn't necessarily fix the other. This debug effort felt very sloppy.

It's also weird looking at a lot of this code. The first assembly function pushes 4 values on the stack and only needed to push 2. I've had my fair share of bugs that make me go to dissembly but that also felt very time wastey here. The author evidently did not have enough of a grasp of what to expect for it to help at all.

While true that nRF should've put something in a log, the author admits they don't support this development flow. It's like the old addage about APIs. Any change no matter how small will break someone's usage.
