So, the tool chain works, but how to get the startup code a little sturdier? So I guess that means - how to write the interrupt vector table? How to zero the bss?

How to do it all with the thumb instruction set in assembly... okay! Sleeves up.

There isn't quite the same perfect playlist (although plenty of great resources!) for what I wanted so this will be multi part to get to a "good" place. This post is mostly about the tool chain (arm-gcc/OpenOCD/gdb)

Hardware is the the Adafruit PyRuler which is a fancy Trinket M0
