Arduino Nano Every not working

Hardware Nano Family Nano Every
1

Hi everybody,

I have a brand new genuine Arduino Every. As soon as installed, the IDE prompted me to install the Nano Every Board Drivers. However when I select Nano Every, it says "Arduino Nano Every, ATMEGA328 on COM5" - yet my Every is a 4809 unit and no sketch will upload.

avrdude: stk500v2_getsync(): timeout communicating with programmer
An error occurred while uploading the sketch

Cheers,

Sean

The 328P is the emulation mode for compiling and has no relation with your upload.

If you want to change the mode, the option is in the tools menu

In order to gather more information that might help us to troubleshoot your problem, I'm going to ask you to post the full output from an upload attempt when in verbose mode.

Please do this:

  1. Select File > Preferences from the Arduino IDE menus.
  2. Uncheck the checkbox next to "Show verbose output during: ☑ compilation".
  3. Check the checkbox next to "Show verbose output during: ☐ upload".
  4. Click the OK button.
  5. Attempt an upload, as you did before.
  6. After the upload fails, you'll see a button on the right side of the orange bar in the Arduino IDE: Copy error messages. Click that button.
    This copies the full output to the clipboard.
  7. Open a forum reply here by clicking the Reply button.
  8. Click the </> icon on the post composer toolbar.
    This will add the forum's code block markup (```) to your reply to make sure the error messages are correctly formatted.
    Code block
  9. Press Ctrl+V.
    This will paste the error output from the upload into the code block.
  10. Move the cursor outside of the code tags before you add any additional text to your reply.
  11. Click the Reply button to post the output.

I found the issue, thank you - there is a "Registers Emulation" which continually reverts to ATMEGA328 - which is quite stupid - as the Every is a 4809 - but to add to the confusion, every upload produces the error;

"avrdude: jtagmkII_initialize(): Cannot locate "flash" and "boot" memories in description"

and many commenters state simply ignore.

Which version of the Arduino IDE are you using?

Please provide detailed instructions we can follow to reproduce the problem. I just gave it a quick try on Arduino IDE 1.8.19 as well as the beta phase Arduino IDE 2.x and didn't notice any unexpected changes to the setting, but I do remember some vaguely similar reports for Arduino IDE 2.x (none at all for 1.x though).

That is correct:
