Additionally, when bringing up new hardware, the knowledge you need in order to understand the state of a malfunctioning device and debug a crash is often stored in the head of the logic designer who wrote the HDL, not exactly something you can look up on StackOverflow.
It's always great when you need to figure out what a particular register means or the architecture of a particular error handling process or something like that, and you open the hardware spec and find "TBD" because it's all still unreleased...
Yeah... just need to have a ton of debug registers included. Especially if it's ASIC.
And yes, Stack Overflow is really not going to help you with pretty much any of this. When doing low level programming, better get comfortable with that there's often no one in the world who can answer your question. Find it out yourself.
