hi
I install Linux on tiny6410 and toggle S2 to nand. the system is running and when the calibrate page display I found the touch is not working.
How can I solve that?

I connect my Capacitive lcd to tiny6410 and install linux on it. I also
change the friendlyarm.ini to this:
#This line cannot be removed. by FriendlyARM(www.arm9.net)

LCD-Type = S70

CheckOneButton=No
Action=install
OS= Linux

VerifyNandWrite=No

StatusType = Beeper| LED

#################### Linux #####################
Linux-BootLoader = Superboot-6410.bin
Linux-Kernel = Linux/zImage
Linux-CommandLine = root=/dev/mtdblock2 rootfstype=yaffs2 init=/linuxrc
console=ttySAC0,115200 skipcali=yes ctp=2
Linux-RootFs-InstallImage = Linux/rootfs_qtopia_qt4.img
Linux-RootFs-RunImage = Linux/rootfs_qtopia_qt4.ext3



and play with ctp=1 (not work),ctp=2 (not work),ctp=3 (not work)
my lcd is S70(when linux is install it writes on screen lcd type is S70
(auto detect))

this device has resistive lcd at first but it was broken then I changed it
to capacitive lcd but touch not work .

Hi,
You can try to burn other systems, such as wince, to determine the S70 is good or bad.
Thanks´╝ü

Tiny6410 does not support capacitive touch. It is factory answer.
