I’m at my wits end with this. Using PlatformIO core 5.1.1 and the Arduino 3.4.0 platform.
Every time I upload to my two Arduino Micros, whether I set them as Leonardos or Micros, I will loose the USB-CDC (serial port) every time. I have to burn a new bootloader in order to get it to work again. On the regular Arduino IDE it works as one would expect.
I have this in my platformio.ini currently:
[env:leonardo] platform = atmelavr board = leonardo framework = arduino lib_deps = mheironimus/Joystick@^2.0.7 debug_tool = simavr build_flags = ; enable USB serial -D PIO_FRAMEWORK_ARDUINO_ENABLE_CDC -D USBCON ; QUIRK: without setting this, no ; data will be received on the serial USB port ; https://github.com/stm32duino/Arduino_Core_STM32/issues/1193 ; monitor_dtr = 1 ; optional: set COM port to monitor here if there are multiple ;monitor_port= COM27
But doesn’t seem to matter what I do, it will not give me the serial port.
Thank you for any help in advance
