LCD touch screen doesn't work

Nguyen Thanh Luan
Hi everyone!
My name is Luan.
I bought a new FriendlyARM and i try to port Linux on it.
But i had a problem when the tslib calibrating utility appears, i could not
touch the screen.
I try my LCD on another KIT and it works perfectly.
I also try another LCD on my KIT. The problem occured again.
What is the problem on my KIT and how to solve it .
Thank you so much !

Well, it will help if you tell us what your "KIT" is and what kernel you
ported and which rootfs you are using and how you downloaded it to the
board.  IE, what bootloader you are using.

Sorry about late davef,
I am using all uboot, kernel and rootf from the DVD which i have from
FriendlyARM.
It worked few times before, but this time it doesn't work :(

Well, taking the images from the DVD and following the DNW downloader guide
should give you a working system.

Something that could help would be, for you to capture the messages that
occur during bootup and look for words like "error" or "unable" or any
other negative comments.  Post the full message that you get on DNW and
maybe someone can help you out.
