R4 Wifi = failed uploading, exit status 1

Development Tools Uploading

This error might be caused by not having the port of the UNO R4 WiFi board selected from the Tools > Port menu in Arduino IDE.

Please perform this experiment to verify that the port you have selected is your Arduino board:

  1. Connect the Arduino board to your computer with a USB cable (if it is not already).
  2. Select Tools > Port from the Arduino IDE menus.

If one of the ports in the menu is labeled with the board name (e.g., "COM42 (Arduino Uno)"), that is the port of your Arduino board.

Select that port from the menu and try uploading again.

If the upload still fails, or if none of the ports in the menu are labeled with the name of your board, add a reply here to let us know and we'll investigate the problem further.
