touch stop working in CE6

after 15-20 sec (5-6 taps on screen) device not responses on taps, only
mouse or keyboard

any ideas?

when touch stops work AD-Convert application shows "-1" value and not
responces too...

I've seen that too.  For me it's not time based, because I've had mine on
for hours and it works, but stops after a number of clicks.
I'll have a look through the code but I'm not sure what to look for...

maybe invalid calibration data leds to adc-driver crash? 
or touch driver crash? 
or timings between clicks?
or movements with pen-down?

but! why adc test shows -1? 
maybe harware failure of ADC?

maybe interrupt problem?

the same problem on 6410?

Same too. Touch stops randomly. Do you run the image from NAND?

(I'm using CE6R3)

yes, NAND, CE6R3 too... 

maybe reinstall CE without R2-R3 and try this image?

i think this problem in 
WINCE600\PLATFORM\Mini2440\SRC\DRIVERS\Touch\s3c2440a_touch.cpp 
and problem with interrupts...

Thanx Alex, You saved my day!

I replaced the s3c2440a_touch.cpp with the one out of CE 5.0 BSP 2009-08-21
(http://www.friendlyarm.net/dl.php?file=wince5-bsp_20090821.zip)
\src\driver\touch.

I'm now testing, but looks good did not stop yet :)

but with s3c2440a_touch.cpp from ce5bsp ADC not working (AD-Convert)
