@SirMichael I have done all that. As I wrote, I did start from an example in the IDE. The program compiles fine and gets loaded onto the core2, which it would not do if I'd choosen the wrong com port. I've even posted the output the core2 sent to the serial console, which would not happen if I'd choosen the wrong port.
So no, your answer is not helpful, it mentions stuff I've done and described in my question.

Hello,
I have a core2 with which I have had problems since day 1. I had thrown it out, but now I'm giving it a ... try.
I've compiled and uploaded many programs that come with the M5core2 library, but I haven't been able to get anything to work.

For example the program: In arduino ide: examples ->ESPInsights -> DiagnosticsSmokeTest.

the compiler throws following errors, but compiles and uploads ok
WARNING: Category '' in library ESP Insights is not valid. Setting to 'Uncategorized'
WARNING: Category '' in library ESP RainMaker is not valid. Setting to 'Uncategorized'
WARNING: Category '' in library WiFiProv is not valid. Setting to 'Uncategorized'

upload goes ok, but the core2 does not show any sign of life.

the serial console output:
..ets Jul 29 2019 12:21:46

and then an endless line of dots are shown on the serial console. No sign of life on the core2

can anyone tell me what's wrong here ?
