Qt-embedded Touch screen problem on IMX53 (SABRE tablet)

Dear All,


        I have been working on a project based on  QT-embedded on linux on imx53 sabre platform.


  • So far  i have installed qt-embedded on target,
  • installed Qt cross compiler on host
  • compiled an app which runs on imx53.


But the problem is qt app does not recognize the touch.... But the touch screen driver is installed

I verified it by doing


export TSLIB_TSDEVICE=/dev/input/ts0

export TSLIB_CALIBFILE=/etc/pointercal

export TSLIB_CONFFILE=/usr/etc/ts.conf


cat /dev/innput/event2 | hexdump


When i do that and touch the screen i get the hex output..... So touch screen is detected by linux.


I have configured the qt-embedded as following.....


./configure -embedded arm -xplatform linux-mxc-g++ -release -prefix /usr/local/Trolltech/Qt-4.6.0/ -no-opengl -glib -qt-gfx-linuxfb -qt-kbd-tty -qt-kbd-linuxinput -qt-mouse-linuxinput -qt-mouse-tslib -little-endian -qt-gfx-linuxfb -host-little-endian -v -opensource -confirm-license -force-pkg-config -no-phonon


so tslib is included.


so how can i make my application get the touch input.. ??
