Touch screen of tiny6410 not work on linux

Question

I have tiny6410 with linux2.6.38 and my touch screen not work after i changes this file(friendlyarm-ts-input.conf). I don't know because of changing this file or not ?
but it works perfect before i do that:
at first I do that:

echo "TSLIB_TSDEVICE=/dev/ttySAC3" > /etc/friendlyarm-ts-input.conf
sync  
reboot

then

echo "TSLIB_TSDEVICE=/dev/s3c2410_serail3"> /etc/friendlyarm-ts-input.conf  
sync  
reboot

again not work . after these codes, my touch dose not work. what can i do now?
I have base Linux on it's CD. Can I use or find touch screen and re-install it or repair it?

Answer 1

at fist I go to dev directory on my device. then search a bout the touchscreen device name: cat /dev/input/ and put this command for each name of the device then i find the device. then change this line in firendlyarm-ts-input.conf TSLIB_TSDEVICE=/dev/touchscreen-1wire then it worked
