    Do you have the right COM port selected? Is your Nano a cheap chinese clone that may not even have the bootloader installed (I have had that before...)? Has it ever worked, or is this your first attempt with this board? Commented Sep 10, 2020 at 12:13

    Does this answer your question? "avrdude: stk500_getsync(): not in sync: resp=0x00," aka Some Dude Named Avr Won't Let Me Upload My Program Commented Sep 10, 2020 at 14:47
  • First try the "Old bootloader" answer Commented Sep 10, 2020 at 16:14
  • The old boot loader fixed it for me. A lot of the Chinese boards I used have that issue. Commented Sep 11, 2020 at 6:14

For me selecting the ATmega328P (Old Bootloader) from the Tools --> Processor menu in the Arduino IDE solved the problem.

I had the same problem with an Arduino Micro. When the upload starts, press once the reset button.
