Hi there,
I have a followed the instructions here and I'm not getting an boot loading data on the screen after copying the tft35a-overlay.dtb file and editing the config file as stated.
The screen initially lights white then goes dark but never with any text. I've tested the LCD by installing the pre-built image on this page and it's working fine. I also notice that the link provided above for the method differs from the WiKi here so not quite sure which one is the right one.
Any pointers would be appreciated.
FYI, version is 2.72 on Pi3 connected to VRM. I also have SSH access if that helps with debugging.
