Troubleshooting

Boards

If there are problems, check

  • Is the correct board selected in the Arduino software?
  • Is the correct serial port selected in the Arduino software (not applicable for Micronucleus bootloader)?
  • Is the board detected, check Windows Device Manager or under Linux run dmesg | grep usb
  • If the board is not detected, try to install the latest drivers: Driver Installation Guide for Windows
  • Troubleshooting Guide from Arduino

Micronucleus Driver Installation

  • Download and Extract/Unzip: Micronucleus Driver (ATtiny)

  • The Micronucleus bootloader is started, if the board is new and no user program is flashed or after the reset button is pressed. On Nanite841 boards the on-board LED is blinking, when the bootloader is running.
