210s: S70 touch doesn't work

Hi,

I bought a new S70 display for my 210s. But unfortunately the touch screen
doesn't work right... I configured the board to S70 in the config file and
flashed a new linux. When I start the new system, I see the calibration
screen. After typing the five points (4 corners and center) the sequence
starts again. This repeats for approx. 5 times. After that qtopia starts
but the touch screen does not work...
I tried to output the ts output to the console, but neither mouse or ts-if
gave an output.

Do you have any ideas how to solve this problem?

Thanks and best regards
Ozzy

Hi,

after a few tries and installations I got the touch screen working; but not
yet in my qt application... Is there any difference between the 1-wire ts
and the "old" ts? The old ts worked fine with my compiled tslib (but on
mini2440).

Best regards
Ozzy

Hi Ozzy, did you get it working?

Hi Andreas,

it was working for some time (after a few fresh installations...).
But since yesterday the ts strikes again. I can calibrate the touch screen
and output the data of of touch by cat /dev/touchscreen...

But when I start Qtopia, and touch the screen, the mouse cursor disappears
and I can't click on a item.

It's the same behavior as in my Qt application.

Do you have any suggestions?

Hi,

it seemed to be a problem of the touchscreen. I changed the display (ot the
pcb), and now everything works fine...

Best regards
Ozzy

Hi Ozzy,

If any issue u came across, then u can debug by doing the /proc/interrupts/

Check whether ur touchscreen driver is generating the interrupts to ur
Processor, and the Processor is able to handle it.

while doing or checking /proc/interrupts/ .......U need to touch the
screen, so that it generates the interrupts, these interrupts are verified
in the path /proc/interrupts/ with respective touch screen driver.

Thanks,
Srikanth.
