Linux/TMDXIDK5718: Touchscreen not working on IDK LCD kit

Part Number: TMDXIDK5718


Tool/software: Linux

Hi,

We are able to see the display but the touch screen on the display is not responding to touch. 

We have this TI dev board running the TI AM 57x processor www.ti.com/.../tmdxidk5718.

We have the optional touch screen connected to it www.ti.com/.../tmdxidk57x-lcd.

We are using the latest TI SDK v4.01.00.06 RT Linux ti-processor-sdk-linux-rt-am57xx-evm-04.01.00.06.

Please let me know if we are missing anything, or if any configuration has to be changed to enable the touch on the touchscreen.

Note that if I connect a mouse, I am able to navigate the display, but only the touchscreen is not working.

Kindest Regards
Ashutosh Naik.
