Co-Pine-ON Processor: Pine64 Boot Co-Processor

Hi, just want share a little experiment I am doing to try to solve my Pine64 Boot Crash/Freeze Problem using a external (MCU) microcontroller to assist it.

The idea is very simple, just "watch" the SystemLED to detect if the system is booting normally, and if NOT, then issue a hardware reset, then, keeping repeating this process until the SystemLED indicates that the system is booting up...

I am trying to document the process here is this tutorial page:

Files, source code, high quality pictures here on GitHub:

The current topic is, more or less, a continuation of the following post:

Still need some simplification/optimization, but the general needed info (and codes) are there...

Since my Pine64 board is showing this fail/crash boot problem, this is the way I am currently trying to resolve the issue and move on to finally trying to do some stuff with this little board...

As my use/tests progress, I will try to keep updates and improvements...

Regards all,

Valter
