Firmware ATmega32u4 sketch arduino with external quartz on 16000

How to flash an arduino ATmega32u4 with external quartz without using bootloader? I understand you just need to fill in the compiled one .hex via avr dude in ATmega32u4 using normal USBASP. If you need to change the fuses, tell me.

  1. Download the IDE and compile the sketch Examples, Basics, Blink for the Arduino Leonardo board.
  2. Find the file Blink. ino. with_bootloader. hex in the /tmp directory (on Linux).
  3. Connect the programmer to the board via the ICSP connector.
  4. Check the FUSE bits with avrdude. For Arduino Leonardo, they are as follows: hfuse 0xD8, lfuse 0xFF, efuse 0xCB.
  5. Flash the controller with the sketch command

avrdude -p m32u4 -c usbasp -P /dev/ttyUSB0 -Uflash:w:Blink.ino.with_bootloader.hex

  1. Disconnect the programmer from the board.
