Reg: Touch Screen

[arjunk]

Hi All,

I am interested in interfacing Touch Screen with my EVB. I am getting Display in my screen, but not able to use Touch Screen. 

 I am using I.MX 6Q SABRE  SDB,Kernel -4.1.15,and for rootfs buildroot 

TSC2004 TOUCH SCREEN CONTROLLER

Kindly advice how to enable and calibrate for touch screen.

You can refer to i.MX_Linux_Release_Notes.

Hi Arjun,

It would be great if you could throw more light on the following:

1. Have you added the touch panel details in the device tree?

2. Was the interrupt for the touch panel configured?

Thanks,

Ramya

Hi , 

 am added the touch screen controller ( TSC2004 ) in device tree , using build root for building linux , even x server also enabled .

The interrupt configuration it ill take automatically or i have to do  manually ?.
right now the interrupt is configured automatically. 

am getting the interrupt one of the side in touch screen . 

Kindly advice how to enable and calibrate for touch screen.
