I do got a wiring_digital.c I have it in /src/core not in variants...
I got an elf file I was able to upload the elf file but the led doesn't blink...
Is it because I dont got the -DARDUINO=151 define.
Also the library does build but is was browsing the source file and an error poped up.
Field 'PIO_OSR' could not be resolved wiring_digital.c /ArduinoDueCore/src/core line 62 Semantic Error
Getting an stm32 working in eclipse is easier than this!
