Everything compiled and built well. Had a problem downloading: "Flash Download failed - Cortex - M0"
Everything compiled and built well.<br>
The issue is the lack of a programming method defined.
Project -> Options for Target xxx (Alt F7) -> Debug tab -> Use ST-Link Debugger -> Settings -> Flash Download ->
Add the STM32G0xx 32KB Flash algorithm with Address Range 080000000H - 08007FFFH.


The green LED, LD2, annode, connects to PA12, pin6, on the STM32G0 part. (Driving this pin high turns the LED on.)
==Additional Websites / Notes:==
The blue push-button, B1, connects T_NRST, pin 4 of the STM32G0 part, to ground when pressed.
(I'm guessing the T_NRST signal is re-assigned as a GPIO for this function.)
