Hello,

            We are interfacing Atmel MXT224E touchscreen with imx6DL Processor in Android Kitkat 4.4.2.

 

We have connected it to I2C-2 and interrupt pin is used in GPIO_1_8.

 

We are getting acknowledge from Touchscreen with Family ID, Variant ID and version correctly.

 

But some problem is with interrupt. When we touch the screen interrupt number is not incremented after checking using

cat /proc/interrupts command but if manually short it to Ground then it will increment the number.

 

For this problem any configuration setting we have to do in kernel setting?
