Apalis TK1 compatible with edt touchscreen

I have connected a 7’’ edt tft-touchscreen to the Ixora carrier board and the Apalis TK1. The display blacklight is switching on but no image.
Does the Apalis TK1 support the edt TFT display ?

Not really, no. As the TK1 SoC does not support any parallel RGB display interface at all one would need to convert from either eDP, LVDS or HDMI. We do have e.g. some customer successfully converting from single channel LVDS to parallel RGB suitable for our EDT range of displays. Please note that the resistiv touch part of it should work once we actually implement a suitable driver and firmware both on the TK1 as well as the K20 side.
