Hi
Im not able to upload anything to my arduino nano every, not even "blink".
The first few times everything worked fine, but then, it randomly startet to bring this error:

The last program i was able to upload is still working.
Does anybody know what to do or is it possible to reset the whole arduino?
Thanks Oliver

did you try to disconnect and reconnect the USB cable?

Yes, also tried different cables and even different computers. In the COM-Port i also see the Nano and can get information from it, just not possible to upload anything...

With all the information and the picture I cannot read I will say you may have a serial flood. Try this:

  1. Power off the board completely
  2. Remove the USB cable
  3. Hold down the Reset button
  4. keep it held down (or, run a jumper wire from the RESET pin to the GND pin).
  5. Still holding down Reset reconnect the USB cable.
  6. Start uploading a sketch that does not have this problem (I use the Blink sketch).
  7. When you see the Receive light blink, release the Reset button
    Note: I have seen this happen several times when I flood the serial output. An indication is the tx light is stuck on.
    If this does not work read the forum guidelines and post the error properly so it can be read.

Out of curiosity, is this specific to the Nano Every? Asking because I can't remember having had issues with serial flooding on AVR based boards.

yes, it is a problem of the USB chip (SAMD11 with arduino's firmware)

Actually no, I have had the problem with several of the AVR boards both OEM and copies. I have not had that problem in the last few years, it may have been fixed in the IDE.
