I have a kuman 3.5 320×480 touch screen and no matter what I do I cant get it to work with my raspberry pi 3+. I tried using the kalipi-tft-config command and going thru the options for my screen. when I reboot its just a blank screen…. im new to these pi’s only had it for 2 days!!! what can I do to get this thing up and running? any help would be great!!!
