Hi All,

I'm having the touch issue on i.MX6 DL sabresd.

In my OS system(wayland qt5.5) I can see there is value print out form /dev/input/event0.

And also I can use evtest to print the location out for me like below.

Event: time 1480479046.645584, type 3 (EV_ABS), code 54 (ABS_MT_POSITION_Y), value 207

But when I touch it to click the Icon above there is nothing happened.

 

event0 did print something out for me while I touch the screen.

So I assumed that driver is not the problem.

What else could be the problem here?

Did I miss something?

 

Thanks in Advanced!
