How can I configure marlin to work between RAMPS and Raspi 3 B by I2C?

Hi,

I've tried to understand the serial port of Marlin, but I didn't find any details about I2C settings in this forum, marlin's documentation and marlin's github. I know that the SERIAL_PORT 0 is to communication through bootloader of Arduino by USB serial. I'm looking for I2C communication directely between RAMPS 1.5 and Raspi. My Arduino is connected with RAMPS 1.5. My goal is the raspi send Gcodes to arduino (marlin). How can I do this? Is it possible?

Regards.

Thank you, MrAlvin! I had already read two issues that you posted. I was a bit confused, but I'll read again.
