I'm glad that I have more than one project going on right now. My main project was going shockingly well until I hit the part with no documentation or information. I will continue with this project but this is the point where a slow crawl is maximum speed. It's going to be a very difficult job.
Progress so far: Information discovered by probing, rough MCU specifications, Architecture, and some capabilities. Thankfully the next part is likely encrypted and signed.
A good point to say I had to stop? Yes it is!
I'm not going to stop.
