Hello, guys.
I'm porting Android to marvell pxa based platform.
and my touch device uses WM9713-touch drvier.
I've followed set up sequence which has been proved in this mailling list,
but can't get touch driver working.
Here's the logcat from my device.
I/EventHub( 45): New device: path=/dev/input/event0 name=wm9713-touch
id=0x10000 (of 0x1) index=1 fd=48 classes=0x2
I/SystemServer( 45): Starting Status Bar Service.
I/EventHub( 45): New device: path=/dev/input/event1 name=pxa27x-keypad
id=0x10001 (of 0x2) index=2 fd=51 classes=0x1
I/EventHub( 45): New keyboard: publicID=65537 device->id=65537
devname='pxa27x-keypad propName='hw.keyboards.65537.devname'
keylayout='/system/usr/keylayout/qwerty.kl'
E/EventHub( 45): could not get driver version for /dev/input/mouse0, Not a
typewriter
I/KeyInputQueue( 45): Device added: id=0x0, name=pxa27x-keypad, classes=1
I/KeyInputQueue( 45): Device added: id=0x10000, name=null, classes=2
I/KeyInputQueue( 45): X: min=150 max=3830 flat=0 fuzz=0
I/KeyInputQueue( 45): Y: min=190 max=3830 flat=0 fuzz=0
I/KeyInputQueue( 45): Pressure: min=0 max=15000 flat=0 fuzz=0
I/KeyInputQueue( 45): Size: unknown values
I/WindowManager( 45): Input configuration changed: { scale=1.0 imsi=0/0
locale=en_US touch=3 key=2/2 nav=3 orien=2 }
I can't figure out what's wrong with my touch device.
Is there any point to check?
Any advice would be helpful.
Thanks in advance.
Daniel Yun.
