    Hello all,

    I just received my 7" LVDS display panel with touch screen. Upon initial boot of either Android or UDoobuntu the touch panel works fine. But after some number of minutes the touch panel stops working altogether. If I reboot the UDOO then the touch panel works again for a while and eventually stops working.

    Is this a known issue? Do I have bad hardware?

    Here is a snippet of my dmesg with what looks to be touchscreen related stuff:

    [ 2.013316] mousedev: PS/2 mouse device common for all mice
    [ 2.019336] usbcore: registered new interface driver usbtouchscreen
    [ 2.026041] Sitronix touch driver 2.9.1
    [ 2.029895] Release date: 20120507
    [ 2.033689] sitronix_reset_ic
    [ 2.158017] resolution = 800 x 480
    [ 2.161979] fw revision (hex) = 0 0 9 26
    [ 2.165903] i2c protocol = 2
    [ 2.168891] max touches = 1
    [ 2.172675] Error: Can not get ID of Sitronix IC
    [ 2.177530] input: sitronix-i2c-touch-mt as /devices/virtual/input/input0

    Any suggestions?

    Regards,
    Jim

    And I was under the impression that the touch controller was 2 point multi-touch capable. According to the dmesg snippet below the driver believes my touch controller is only a single touch....


    Code:
    [ 2.013316] mousedev: PS/2 mouse device common for all mice
[ 2.019336] usbcore: registered new interface driver usbtouchscreen
[ 2.026041] Sitronix touch driver 2.9.1
[ 2.029895] Release date: 20120507
[ 2.033689] sitronix_reset_ic
[ 2.158017] resolution = 800 x 480
[ 2.161979] fw revision (hex) = 0 0 9 26
[ 2.165903] i2c protocol = 2
[ 2.168891] max touches = 1

    I just tried my 7" LVDS with UDOO Quad and Android OS.

    here's my dmesg:

    Code:
    <6>mousedev: PS/2 mouse device common for all mice
<6>usbcore: registered new interface driver usbtouchscreen
<4>Sitronix touch driver 2.9.1
<4>Release date: 20120507
<4>resolution = 800 x 480
<4>fw revision (hex) = 0 0 9 26
<4>i2c protocol = 2 
<4>max touches = 2 
<6>input: sitronix-i2c-touch-mt as /devices/virtual/input/input0
    As you can see I've got 2 touches and i usually use my UDOO the whole day without any problem.

    My thought is that your problem is hardware related. I suggest you to open a ticket in our CustomerCare section asking for an RMA: http://www.udoo.org/customer-care/

    I have an issue similar to this as well. In my case, I get the startup messages in the first post. However, the touch screen stop working after a random amount of time and in the kernel messages I get:

    send finger command error (-5)
    read finger error (-5)

    It looks like an issue where the i2c fails to communicate with the touchscreen and the kernel module quits. I am trying to find a way to restart the kernel module that prints this, but so far I have been unsuccessful.
