Chromebook support for Arduino UNO R4 WiFi

Official Hardware Classic UNO R4 WiFi
1

I have a new Acer Chromebook Spin 714 Chromebook running version 122.0.6261.118 and I just bought an Arduino UNO R4 WiFI board.

I am running Visual studio (Version: 1.87.2) and PlatformIO (Core 6.1.13·Home 3.4.4) under Linux VM but the board is not getting recognized when I plug in. Basically nothing happens. I tried it with another board, and multiple other cables like a USB - USB-C and a USB-C to USB-C no luck.

I tried a USB thumb drive and it does work as expected so the USB port works.

I also updated all packages. I am at a verge to quit my initial attempt at making my incursion into Arduino programming.

Has anybody encounter problems similar to mine or have a way to force or ensure my Chromebook USB ports are correctly detecting the board and making it available to Linux?

Thank you!!!

I teach at a school and every one of my kids has a Chromebook. We've been using Uno r3s for a while. They seem to work when the students install some kind of chrome plug-in called Arduino create for education.

I recently got an r4 because I am considering updating all of the arduinos. So far, the r4 does not work on any of the Chromebooks.

Thanks, so far that seems to be the observations I have run into.

How do I get a replacement chip? I have a few that are the worse for wear.

You can buy blank ATmega328Ps from DigiKey, from Mouser, and even from Amazon if you're feeling lucky.

You can also buy the chip with the bootloader already programmed, or you can easily build a standalone bootloader programmer to program the bootloader into the blank chip:

Huh. So it was. I've copied your working link in to prevent future headscratching. Good catch; must have been gremlins.

Running Linux via VM can sometimes be problematic if the setup wasn't done properly. Check Fix port access on Linux and Fix udev rules on Linux

Hi @jose_berm. In case you would be interested in an alternative solution, you can use your UNO R4 WiFi board in the ChromeBook's native ChromeOS environment with the web-based Arduino Cloud Editor:

https://docs.arduino.cc/arduino-cloud/guides/cloud-editor

https://support.arduino.cc/hc/en-us/articles/360016495639-Use-Arduino-with-Chromebook#use-the-cloud-editor-on-chromebook

Is that when using the deprecated "Arduino Create for Education" app? If so, have you tried using the new Cloud Editor instead of the app?
