Flash Bootloader to Creality Ender 3 Pro (ATMega1284p, Melzi, Sanguino) using a Raspberry Pi only

My raspberry is running Raspbian

  1. Setup avrdude on Raspberry following this guide: http://archive.today/U0WzQ

    The wiring diagram works exactly the same for the Creality Melzi board

    To run the test, replace atmega328p with atmega1284p
