    raise SerialException("could not open port {!r}: {!r}".format(self.portstr, ctypes.WinError()))
serial.serialutil.SerialException: could not open port '/??/COM12': WindowsError(123, 'The filename, directory name, or volume label syntax is incorrect.')
make: *** [/c/msys32/home/tuant/esp/esp-idf/components/esptool_py/Makefile.projbuild:55: flash] Error 1
Solution

  • What have you got in your Serial Flasher Config for the serial port? Make sure you erase anything that's there and have only COM12. My guess is you have slashes left over from what the default is.
