Skr mini e3 v1.2 + tft 35 v2 problem

[youneslak]

Hi,
I have connected my tft 35 v2 to my skr mini e3 v1.2 with marlin 2.0, but the screen doesn't show anything, it's on but nothing is showing.
I have followed the right wiring and still nothing.
Any help will be great
Thank you

Set in config.h
#define SERIAL_PORT 2
#define SERIAL_PORT_2 -1

Update the firmware for TFT

If you have it correctly wired up, it should work

Thanks you @rydol
Is there a way to update the firmware even if the screen is not showing anything?

[rydol]

@youneslak The screen should light up with its basic menu if its wired correctly. Even if you just power it up with 5v. Then you should see message: printer connected or no pritner connected at least.
How did you plug it to the board ?

@rydol
I have connect it just like this wiring scheme

but still the screen is just blank no menu or anything

[rydol]

@youneslak Seems good to me, what happens when you connect only 5V and GND ?

[youneslak]

I haven't wired it with only 5v and GND.
I thought that it has to work directly without any problem, since i brought the motherboard and the tft as a pack.
