So i have a just bought an RRF board and im trying to use the Ender 3 v2 screen ( DWIN ) with it, already changed all the parameter on marlin that are necessary to use the DWIN display, and also rewire the RX and TX where they should be following your diagrams, but when y try to flash the firmware i just have a blank screen, the board blinks as it is flashing, and converts the .bin like it was flashed.

Tried on:

Marlin latest bugfix (2.0.x)

BTT-E3-RRF Firmware code

My previous working compile for the 4.2.7 board i had.

Marlin.zip

You will need to adjust the display cable connection. Look for inspiration here.

If you use #define LCD_SERIAL_PORT 1 You should able to use tx & rx pin from the tft port
