I have a genuine Arduino Nano Every board that isn't showing up quite right. I actually have 2 hooked up to the computer on different ports and one of them, when I click on 'Port' shows as:

COM12 (Arduino Nano Every)

But the other one just shows up as:


The COM18 device used to have (Arduino Nano Every), but doesn't anymore. The other problem I have is that when I try to upload a sketch to the device, it compiles and gets to uploading and then has a bunch of errors:

avrdude: jtagmkII_getsync(): sign-on command: status -1
avrdude: jtagmkII_getsync(): sign-on command: status -1
avrdude: jtagmkII_getsync(): sign-on command: status -1
An error occurred while uploading the sketch

I've tried changing the selection on "Registers emulation:" between ATMEGO328 and None (ATMEGA4809) but I get the same errors whenever I try to upload a sketch. Is my Every bricked? Or is there some way to revive it?

I'm not sure why this happened. I was able to upload sketches before, and have barely even used this device.

Does somebody have any ideas on how to get this working again, or should I just throw it away and get another one?

    the USB chip on Nano Every is a SAMD11 with Arduino firmware. you could try to flash the firmware. arduino.cc/en/Guide/NANOEvery#firmware-for-samd11d14a – Juraj Aug 20 '20 at 5:06

    Your programmer chip is bricked. Lol – Oggy Saud Aug 20 '20 at 10:56

    I'm not the one who voted down, but you might show some effort, like trying to restore the bootloader. Both symptoms are clear: The Arduino does not work as the expected USB device any more. You might need to use another programmer (another Arduino for example) to access it. – the busybee Aug 21 '20 at 7:15

    Don't worry about the down-vote. If you got 20 you might worry. :) – Nick Gammon Aug 21 '20 at 9:22
