Dear friends! I have worked on 2440 touch screen worked perfectly. Now I want switch to tiny2451. for testing my touch screen I used cat /dev/input/event0 ---> It shows some ascii character in my debug port. Same thing I had tried for tiny2451 board cat /dev/input/event0---> It does not show anything. But I am getting the same by cat /dev/touchscreen-1wire --->It shows some ascii character in my debug port. Now my question is : what will be the change in the /etc/profile file. Below is my 2440 board configuration. ========================================================================= # Ash profile # vim: syntax=sh # No core files by default ulimit -S -c 0 > /dev/null 2>&1 USER="`id -un`" LOGNAME=$USER PS1='[\u@\h \W]\# ' PATH=$PATH HOSTNAME=`/bin/hostname` export USER LOGNAME PS1 PATH export LD_LIBRARY_PATH=/usr/local/lib export QTDIR=/usr/local/Qt export QWS_MOUSE_PROTO=tslib:/dev/input/event0 export TSLIB_CALIBFILE=/etc/pointercal export TSLIB_CONFFILE=/usr/local/etc/ts.conf export TSLIB_CONSOLEDEVICE=none export TSLIB_FBDEVICE=/dev/fb0 export TSLIB_PLUGINDER=/usr/local/lib/ts export TSLIB_TSDEVICE=/usr/local/lib/ts export TSLIB_TSEVENTTYPE=INPUT export QWS_DISPLAY=LinuxFB:mmWidth=105:mmHeight=140 ======================================================================== Please, reply who have worked on tiny2451. Thanks in advance.
