MKS Gen L V1.0 + TFT28 + Marlin 2.0.9.2

Hi y'all,

my skill with the electronic and Firmware is so bad, so I would like just a little help.

In my office, I have found a MKS Gen L V1.0 motherboard (not a SGen !), and one MKS TFT28 V4.0.


I try to build a printer with these stuff.
I have download Marlin 2.0.9.2, which makes running my printer with a Ramps 1.4 (without trouble)

To use the new stuff, I have re-work the firmware like this in configuration.h :

142 #define MOTHERBOARD BOARD_MKS_GEN_L

with this new motherboard, no trouble during the "build stage" under VScode + PlateformIO

2715 #define TFT_GENERIC
2722 #define TFT_INTERFACE_SPI
2725 #define TFT_RES_320x240
2742 #define TFT_COLOR_UI

you can find below the trouble message after a "build stage"

Several attempts brought me to this result.
Would you know how to tell me to remedy this problem ?

thank you
(sorry for my bad english )

the MKS TFT28 V4.0 is not a marlin controlled tft

do not enable any of these
2715 #define TFT_GENERIC
2722 #define TFT_INTERFACE_SPI
2725 #define TFT_RES_320x240
2742 #define TFT_COLOR_UI

The is actually a controller in its own right and as such you send and receive gcode from it.

In Marlin it is just a serial port, so enable serial port, the port you connected the tft to.

This is connected to AUX-1 this is serial port 0, ie you cant have usb plugged in at the same time
