Error using ts_calibrate with LCD touchscreen

Hi !

I connect my touch screen LCD to the target. At start-up i export all theses varaibles:

ln -s /dev/input/event0 /dev/input/touchscreen0
export QWS_MOUSE_PROTO='Tslib: /dev/input/touchscreen0'
export TSLIB_CALIBFILE='/etc/pointercal'
export TSLIB_CONFFILE='/etc/ts.conf'
export TSLIB_CONSOLEDEVICE='none'
export TSLIB_FBDEVICE='/dev/fb0'
export TSLIB_PLUGINDIR='/lib/ts'
export TSLIB_TSDEVICE='/dev/input/touchscreen0'
export MULTI_OPTS="Multi: LinuxFb:/dev/fb0 LinuxFb:/dev/fb1"

but when i execute ts_calibrate, there is an error:

Couldnt load module input
No raw modules loaded.
ts_config: Success

It is strange because i use in my ts.conf file the instruction:

module_raw input

module pthres pmin=1
module variance delta=30
module dejitter delta=100
module linear

 

It seems that module_raw input doesn't work, do you know why ?

 

Thanks,
