Hi @rupsimrd
You do not use this STM32 core but this one:
https://github.com/rogerclarkmelbourne/Arduino_STM32

[rupsimrd]

just tried it, that doesnt help it

What did you tried?

OK but as I said you used an other core than Arduino_Core_STM32 so please use the forum or open an issue on the correct repo.
