I updated my firmware to the latest version. I connected the rs232 cable to the AUX1 of ramps as well as EXP1 and EXP2 from TFT to the ramps. With this cable configuration, the TFT stars and gives me the 2 options to select, Marlin Mode or BTT mode, but the screen does not respond to any touch. If I disconnect EXP1/EXP2 but leave the rs232 cable connected, the BTT mode works but Marlin does not. Again, any help is appreciated.
