Good Morning Sir, Happy New Year!
I should have been more clear, sorry for the confusion. I was reading off the blue pill pin assignments from the board, and yes I did think that SWO was odd but it appears that is all they had room for. The Nucleo does not have the pin names available on the board. Believe me, I have checked these connections several times against the datasheet, thinking that was the cause, but then remembering that I was successfully able to upload the firmware from the Arduino and the same setup persists as I have not changed anything. I even confirmed what the Arduino IDE already told me by switching the delay values in the program to affect the duty cycle of the blinking LED, so I could visually confirm. Also remember that I can connect with the utility and read the board. This is where I got the output from STLINK to post here.
Also, here is the new verbose output from VSCode/PlatformIO. Thank you for the debug level suggestion!!
[env:genericSTM32F103C8]
platform = ststm32
lib_extra_dirs = ~/Documents/Arduino/libraries
board = genericSTM32F103C8
framework = arduino
upload_port = COM4
debug_tool = stlink
upload_protocol = stlink
build_flags = -DCORE_DEBUG_LEVEL=1
And new verbose output.
