Tool/software: Linux
Hello,
I am workning on AM3352 based custom board.
I need to run touch screen on qt GUI application.
In that Qt application GUI on LCD is working fine without "weston", and with "-platform linuxfb".
But I am facing problem when i touch on the touch screen, I am getting X and Y coordinate, I checked with "evtest" utility.
In Matrix GUI application(running as -platform linuxfb) or any custom qt application touch is not working.
But "pinchzoom" example which is available in the filesyatem it is working.(Zoom in Zoom out working fine in pinchzoom).
Below is the log for referance.

It's look like touch driver working properly but matrix GUI application not accepting the touch which is use "linuxfb" as a platform.
I also cross compiled "tslib" and try to run "ts_calibrate", but looks like calibration is not happening.
below is the log and env setup for your referance.

/---------------------- Out put of ts_calibrate -------------------------/
root@am335x-evm:~/Tslib/Install/bin# ./ts_calibrate
xres = 480, yres = 272
/----------------------------------------------------------------------------/
Display is coming on screen calibration curser is also comming on screen.
But when I touch there is not calibration going to happen, at that time in "evtest" utility I can see the X and Y coordinate.
Please do the needful.
