Touchscreen TSC2007 and Removing phone objects

Hi,

First I am trying to enable touchscreen.

I followed instructions on touchscreen guide.

Enabled tsc 2007,spi in config.

TSC 2007 connected to INT 130 pin.

I couldnt get any input from getevent.

Also I am trying to disable phone objects.

I followed http://processors.wiki.ti.com/index.php/Android_gingerbread_memory_analysis_for_non-phone_device

But when I boot up I got com.android.phone has stopped unexpectedly error.

All ideas will be appreciated.

  • Hi,

    1. What is the output for $getevent -p

    2. Regarding removing phone objects, is it affecting your boot or any other activity...I means after boot luncher is coming properly or not

    Hi,

    1. I suspect touch screen is not enable in kernel config. Or it is not registered as input device.

    As in input device list, I could not see touch screen tsc2007

    Kindly look into same.

     

    BR,

  • In reply to Satish Patel:

    Hi satish,

    Im sure I opened tsc in config and I saw tsc2007.o created.

    But I m not sure about configuration.For example pin muxing.I think I should configure which pin tsc 2007 connected etc..

  • In reply to Batuhan Gundogdu:

    Hi Batuhan,

    I thought you are looking into the issue, why tsc2007 not getting registered at input device.

    Have you refer to porting guide

    http://processors.wiki.ti.com/index.php/TI-Android-GingerBread-2.3.4-DevKit-2.1_PortingGuides#Touchscreen

    I hope you will get some useful information from this.
