Touch screen not working on mini2440

Hi Guys,

I am using the linux on my PC.I have ported kernel and u-boot on
min2440.But when I am running some application touchscreen seems to disable
at that time.

Please tell what is the issue ?

Suggest you post the boot messages, maybe there is a clue in there.

Do you even see a flashing cursor at any stage?

Are you following some tutorial?

Which kernel, which file system ?

hello experts,
i have the same problem i used thw W35 screen with mini2440(1135)
i load all the things viz supervivi kernel qtoipa.
but when on and connect the screen and it said to touch the screen...all
goes well but after that curser goes mad as i clicked "OK" button it go up
and down...
can any one solve this??
waiting for reply.

Have you done a ts_calibrate ?

Try searching <w35 ts_calibrate>

I am not sure for which screen, but I recall a change to a line in:
/etc/ts.conf

Try searching for that term.

Hi Davef,

I am using 2.6.32.3 kernel, the one that comes with DVD and file-system is
qtopia qt4.

Yes I see blinking cursor at LCD.

Can you tell me which touchscreen driver is used in mini2440.I want the
path of the driver.A/c to me it is
/driver/input/touchscreen/mini2440_1wire_host.

I got this post for making touchscreen work, they doing some modfication in
board file(arch/arm/mach-s3c2440/mach-mini2440.c).But I am not sure whether
this will work or not.

Whether I have to cross compile tslib ?What is the function of tslib ?

Abhi
