Skr mini e3 v3 with tft35 e3 v3.0

[Fr0st]

Hey, I'm trying for the life of me to get this touch screen system to work. I put this in my ender 3 v2, and was planning on just using the touch screen so I have it all hooked up, can even access marlin mode. But no matter what I do for setting it up I keep getting no printer attached. All the wiring is good the display settings match to each other. Does anyone know how I can fix it?
