BTT tft35v3.0 not compatible with BTT E3 RFF v1.1

[obionekenewbie]

Hi, i recently bought the BTT E3 RFF v1.1 to try the idex mode and the TFT35 V3.0 touchscreen updated to 0.27 but when i compile in VS code i cant choose REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER beacouse if i do i get this error:Only CR10_STOCKDISPLAY, ZONESTAR_LCD, ENDER2_STOCKDISPLAY, MKS_MINI_12864, and TFTGLCDPANEL(SPI|I2C) are currently supported on the BTT_E3_RRF. So can you tell me if this board and tft are compatible and in wich way i should set them to work fine? beacouse if i choose CR10_STOCKDISPLAY it "works" only in marlin mode but with a lot of screen bugs and in touch mode the tft says printer not attacked even if try changing the baudrate ( current settings: SERIAL_PORT 3, SERIAL_PORT_2 -1, BAUDRATE 115200.) Thanks for attention. Kind regards.

For touch mode communication, you must connect the serial cable and set serial port 1 SERIAL_PORT 1

OK I've had the same problem, and changing the serial port to 1 still gives me the same error. Don't understand why this would be released if only compatible with so few LCD displays, and a few searches this is a very big problem with no known solution.

What's your mistake?
