If you have timeout issue pls ensure the crystal used on board is 16Mhz.

mega.menu.cpu.atmega2560.upload.protocol=wiring
To:
mega.menu.cpu.atmega2560.upload.protocol=stk500v2

I was having this issue with Arduino Uno. The fix is pretty embarrassing: Tools -> Board (change it to "Arduino/Genuino Uno").

For some reason I had Board  "Arduino/Genuino Mega or Mega 2560" defined  :smiley-roll:
