Ardunio ramps 1.4 with mega 2560 "unknown board"

Official Hardware Mega Mega 2560
1

Ok, so i just downloaded the newest arduino and marlin. I have hooked the blue mega 2560 board to the red ramps board and the LCD screen as well. I have not hooked up any motors or heat sources or jumpers

I then hooked up the usb cable and the screen powers on and i have a red led that blinks every 3 seconds.

Device manager shows com 10 as USB - SERIAL CH340 not sure if that is correct.

I open the Marlin.ino file in arduino IDE. I then install the u8glib libraries as instructed to do in the attached youtube video.

Board is set to mega2560 and so is the processor.

i then switch to com port 10 and hit "get board info" and it errors out saying "unkown board" and SN null

What do i need to do next to get the board information correct or does that not matter?

I did try to upload the config.h to the board and the led was blinking like crazy, no errors but when i power on with just the PSU, nothing on the screen. just a black square and blue light

removed comments from the following lines
#define REPRAP_DISCOUNT_SMART_CONTROLLER
#define SDSUPPORT

Thats all i changed. The lcd i am using is a reprap discount full graphic smart controller.

thanks

It is correct and shows that this isn't an original Arduino board but a clone.

"get board info" only works with original Arduino boards or with 100% clones, using the same serial/USB converter as the original. But that should not matter when uploading a sketch ( if the board is set correctly in IDE )

Hello,MicroBahaner!
I wanna use Full Graphic Smart Controller with ardunio ramps 1.4 with mega 2560
I downloaded newest marlin.
But, "Full Graphic Smart Controller" instructions on Youtube are 5 or 6 years old, and I can't get it to display properly even with the same marlin modifications as in that video.
Could you please explain in detail the latest marlin settings?
