Hello,
Very likely a PEBKAC error here, as I have very little experience with an older Arduino Uno, but I recently purchased an Arduino Nano Every for a new project. I went to Board Manager, installed the MegaAVR boards package, and chose my board as Arduino Nano Every. I don't understand "Registers emulation" so I try both the default value and "none." I plug my board in and Port gives me the only option "COM 3 (Arduino Nano RP2040 Connect)." Clicking Get Board Info returns the information in the image below. Attempting to upload a sketch returns: "avrdude: jtagmkII_initialize(): Cannot locate "flash" and "boot" memories in description"
Is this the expected behavior?
My board was purchased from the official store.arduino.cc.
I just set up a Nano Every to see if I had the same issue.
First, I updated the main package in board manager.
Then, I installed MegaAVR package.
Then, I restarted my IDE.
Hi @thackp. There is a bug in the 3rd party Earle F. Philhower, III "Raspberry Pi Pico/RP2040" boards platform which causes the Nano Every to be identified as an "Arduino Nano RP2040 Connect" board (The "Raspberry Pi Pico/RP2040" platform provides support for the Nano RP2040 Connect board in addition to Arduino's official "Mbed OS Nano Boards" platform).
I have submitted a bug report to the "Raspberry Pi Pico/RP2040" boards platform developers about this:
Until then, please just ignore this incorrect board identification. COM3 is the port of your Nano Every.
Yes. That is only an informational message printed by the upload tool. As long as the upload finishes successfully, all is well.
