7” resistive display no touch input on Colibri IMX8X

We are having a Colibri IMX8X SOC with a Colibri evaluation board (2GB BT/WIFI) and a Toradex 7" resistive touch screen display.
OS: Android 11 from Kynetics

The display works but without any touch input. Is there anything to be done to enable the touch input?
