[Gumstix-users] Overo Fire touch screen not working

[Jeff G. <Jef...@br...>]

Hello,

 

I have an Overo Fire "COM Pack" that my company ordered in November.

The touch screen does not work.

 

I went through the steps from the "Get Started with Overo
Computer-on-Module" page in the section  "Using the LCD Screen" without
any issues.

 

This successfully started the LCD. The screen lights up on boot and a
configuration window for enlightenment pops up for choosing a language.
If I plug in a usb mouse then I can cursor around.

 

Looking around, I do not see any touchscreen driver loaded: there is no
entry for /dev/ts or dev/input/touchscreen or any such.

When I try to load the driver manually by doing "modprobe ads7846", I
get the following error as reported by dmesg:

ads7846 spi1.0: touchscreen, irq 274

ads7846 spi1.0: no device detected, test read result was 0x00000000

 

So of course without a driver, the 'ts_calibrate' utility fails with
this error message:

ts_open: No such file or directory

 

Everything is untouched (except for the 'setenv defaultdisplay lcd43' in
the U-Boot... everything is pristine as delivered in the box.

 

I really need this to work. I saw some reports about IC6 issues, but I
do not know how to check for this.

 

You'd think that everything would simply work right out of the box. I
would appreciate any help with this problem.

 

Thanks,

Jeff
