Sketches Can't Upload to Factory-Fresh Nano Every

Hey folks, first-time builder here. I just got my Arduino Nano Every in the mail, and I’m trying to upload a modified version of the blink example to my new brand-new board. However, every time I try to upload a sketch, the IDE just spins its wheels for around 5 minutes before giving up. I’ve been trying to look through similar questions and haven’t found anything that has solved my issue. My OS is Windows 10.

Here’s a snippet of the log (I’ve turned on verbose reporting for compilation and upload):

Arduino: 1.8.13 (Windows 10), Board: “Arduino Nano Every, None (ATMEGA4809)”

An error occurred while uploading the sketch

Here are the settings I’m currently using:

  • Board is set to Arduino Nano Every, using Arduino MegaAVR Boards 1.8.6
  • Registers emulation: none (ATMEGA4809)
  • Port: COM1 (there are no other options that appear for me, and no other port pops up in the device manager when I plug the board in)
  • Programmer: Onboard Atmel mEDBG (UNO WiFi Rev2)

Here’s what I’ve tried so far:

  • Disabled antivirus
  • Uninstalled and reinstalled Arduino IDE
  • Turning on registers emulation
  • Restarting computer
  • Resetting board
  • Using different USB cables
  • Using different USB ports (3.0 and 2.0)
  • Manually installing Arduino drivers to Windows (Windows said the most up-to-date drivers were already installed after I specified the directory to search in)
  • Nothing is connected to the board.
  • The pin-13 LED blinks, so there’s a bootloader on the board.
  • I’ve reset the board before uploading.

Any help would be very much appreciated. I’m about to give up and just return the board and swap it for a different one.

When you open the Arduino IDE's Tools > Port menu, does it say "COM1 (Arduino Nano Every)", or does it only say "COM1"?

Hi, from what you explained it seems that the board is not being detected by the computer. You might want to check your device manager to see if the board is being recognized or not. Also, when you uninstalled the IDE did you make sure you deleted the Arduin15 folder.

It only says "COM1". There is no mention of the Every specifically.

I posted this several places because responses can be slow, and each responder has a different, useful idea to try. I'd run out of my own ideas, so I cast a wide net.

The board does not seem to be recognized. I posted my question on the Arduino subreddit, and it seems that perhaps the board is simply defective. No unknown USB device is listed in my device manager and no new entry appears in the device manager when I connect the board. As I've said, I have tried multiple USB cables and ports, and also tried it on two different Windows 10 computers.
