Flashing Arduino OPTA bricks serial port. #845
Description
When flashing the Arduino OPTA with my PlatformIO project the first time, everything works fine. On the second try I get the following error:

================================================================= [FAILED] Took 10.31 seconds ==In this state flashing is not possible neither with PlatformIO nor with the Arduino IDE.
To flash the OPTA again, the reset button has to be pressed twice, bringing it into bootloader mode. Unfortunately flashing in this state is not possible with PlatformIO:

================================================================= [FAILED] Took 0.35 seconds =================================================================Using the Arduino IDE the OPTA can be flashed without any issues. Afterward it can be flashed without pressing the reset button. Until it is flashed again with PlatformIO.
I also observed, that any use of the Serial interface is not possible (when compiling and flashing with PlatformIO). Which could be related to the flashing issue and/or #835 and/or #763
