Teching techs video: Beginner guide to editing Marlin firmware - step by step - UPDATE IN DESCRIPTION - YouTube
i got firmware to compile for mega2560 but thats it, its 8bit and the default one the environment setup. i need the board microcontroller for the creality 4.2.7 board thats 32bit, i made a .hex firmware but i need .bin 32bit. guess i cant figure out what controller the board uses.
i got the marlin and marlin configs from the official marlin github 2.0.x newest stable firmware repo.
