first-time builder here. I just got my Arduino Nano Every in the mail from Mouser, 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):

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.

  • see in Device Manager the USB devices and the COM ports if the descriptions match. did you try a different USB cable?

  • @Juraj I'm not sure what you mean by whether the USB devices and COM ports match; their names, descriptions under "details" tab, and location are all different. I've tried two different cables, yes.

    that programmer selection is ignored for Serial upload. the upload output in Question is right for Every. COM1 is no the Every. look in Device Manager for unknown USB devices

    I've already done that. When I uninstalled the arduino IDE I uninstalled all associated files, including board packages.

    I'm aware of that. I manually deleted all Arduino files everywhere I found them on my computer; original installation, documents library, and appdata.

Reset to default

Here is a trick I use on some boards but first be the baud rate is the same in the terminal as in the sketch (Serial.begin(115200). If so then remove everything then put a jumper between ground and reset. Then put a jumper between TX and RX (pin o and pin 1 on uno). launch the IDE and what you type in the console should be echoed back to you. If this works the hardware is connected fine.

I was getting the same error when I got my brand new Nano Every.

I had Registers emulation: ATMEGA328

I changed it to None (ATMEGA4809) and it uploaded without problems.

I'm on ubuntu 18.04, and this is after the IDE prompted me to install the megaAVR boards library (1.8.7) of course.

    the emulation selection has nothing to do with the upload. it was something else.

  • Perhaps. Nevertheless I was having trouble uploading my sketch to my arduino nano every. I googled the error and landed on this question. After reading the question and answers, I realized emulation could be my problem, which it was. This answer was an attempt to aid others with my same problem.
