Problem Downloading code to Wifi Rev2

My code compiles fine but when I get to the downloading part of a new install I get the following error. At the bottom of the error list it says the board is not connected but when I get the board info the window shows the correct info.

Arduino: 1.8.9 (Windows Store 1.8.21.0) (Windows 10), Board: "Arduino Uno WiFi Rev2, None (ATMEGA4809)"

Bernardo, Did you change your code so that you were forcing the compiler to use more flash instead of RAM? IE Serial.print(F("Write something on the Serial Monitor that is stored in FLASH")); Or const char StyleHTML[] =" some long string like a web page”; My issue started after I started using these.

Unfortunately, that is not my case.

[btabuenca]

Just tried with a 2nd Arduino UNO wifi rev-2 that was working this morning. Now I get the same message and did not modified any line of code.

This is how things happened:

1. I tested it in Genuino linux this morning. Worked!
2. I tested it in Genuino Mac this afternoon. Worked!
3. I tested it in Genuino linux this afternoon. Did not work :(
4. I tested it in Genuino Mac this afternoon. Did not work :(

Now I have 2 Arduinos UNO wifi rev-2 not working. I cannot upload any program

Please let me know if I could help

Hi everyone,
we are bisecting the issue to understand what could be the root cause. Feel free to contact the support for a replacement in the meantime.

@TimEllis2019 Can you please send us a top photo of your board?

[btabuenca]

@agdl Here you are a photo from mine

Photo attached. Please let me know if you need anything else.

@TimEllis2019 email attachments don't work on GitHub. Please open this issue thread in your browser: #33
and then attach the photo in a reply made right to the thread on GitHub, rather than via an email reply.

@TimEllis2019 , sure, feel free to contact support linking this thread so we'll be able to track the issue is a sane way.

Since yesterday I have the same problem with my Arduino Uno Wifi Rev 2. It would be great if someone finds a solution for this bug. I also wrote an email to the Arduino support and I am waiting for an answer.

Is it maybe possible to exchange the defect Arduino, because it is in the warranty time?

My actual project is a multi medial steering platform for the Tinkerkit Braccio and the Arduino is the leading component for me.
