Description
After installing all boards/libraries etc with new RPi OS upgrade everything works really smooth. The arduino IDE 1.8.19 runs well...
I can compile and upload for all my different boards except the UNO WIFI Rev2. I have removed board def, reinstalled, rebooted, installed prior versions and nothing seems to get over this error...
It was working before the upgrade.
Adding additional verbose error messages...
Arduino: 1.8.19 (Linux), Board: "Arduino Uno WiFi Rev2, None (ATMEGA4809)"
