Using the latest bugfix-2.1.x, replace /Marlin/Marlin/src/pins/lpc1769/pins_MKS_SGEN_L_V2.h with this file:
pins_MKS_SGEN_L_V2.h.zip

It compiles, but I haven't tested it on real hardware.

Perfect.. Thanks.. i will see if it works on the hardware :D

That's expected when you migrate major versions of Marlin and means you probably weren't running the latest bugfix-2.1.x before flashing.

And the screen is black no background light

I copied the pin layout from another pins file hoping EXP numbering would match up, so I'll have to look at this more closely when I wrap up some other work and can test on real hardware.

#define TOUCH_BUTTONS_HW_SPI_DEVICE 1 should be 2

but other than that... it looks ok.

The back light not working doesn't make sense its just an IO pin, are you sure you plugged display exp1 to board exp1 and display exp2 to board exp2 correctly and not switched over?

NOTE Do not just switch these over. check it thoroughly

If you look at the pin diagram for MKS TS35 V2.0 https://github.com/makerbase-mks/MKS-TFT-Hardware/blob/master/MKS%20TS35/MKS%20TS35%20V2.0_001/MKS%20TS35%20V2.0_001%20PIN.pdf
You see that tft exp1 takes 5v as provided by the motherboard exp1 port
but tft exp2 can take 3.3v, if you plug this into motherboard exp1 you will most likely damage your display by putting 5v on the 3.3v line

See #27183 for the verified fix. There's still a quark with a BTT TFT35 SPI display on this motherboard, but I'll look into that later since it'll be a rare combination.

TOUCH_BUTTONS_HW_SPI_DEVICE

Where do i find that setting ? and yes. the machin was working before update

[ellensp]

In the originally provided updated pins_MKS_SGEN_L_V2.h.zip, it has been updated in #27183

[DragonLord1981]

How do i download that file ? haha sorry.. i tried all the ways that i know
