> DrAzzy: > That error message has nothing to do with Serial.print() - that's an error from the upload or bootloading process. Do you have an Arduino with jtag2updi installed on it connected to the ATtiny1614? I know that and yes I have an Arduino Uno with jtag2updi connected to the ATtiny1614. > DrAzzy: > You cannot upload via the serial port unless you are using the (optiboot) board definition, and have used a UPDI programmer (like jtag2updi) to install the bootloader. I know know, but I don't have an optiboot. I successfully loaded basic sketches like the blink, following this tutorial [https://www.youtube.com/watch?v=AL9vK\_xMt4E](https://www.youtube.com/watch?v=AL9vK_xMt4E) I need to print something on the serial monitor and I found out I can use a serial adapter, but I don't know how to use it and I can't find a simple guide about it. --- _[View the full topic](https://forum.arduino.cc/t/attiny1614-serial-print/669298)._
