Hi,guys I have ported android 2.6.25 to my s3c smdk6410,and the filesystem is donut that I built from the source code.Now I can boot it up and see the main window.But when touching the item ,it does not have any response at all.
My touchscreen driver src file is s3c_ts.c. I built tslib and calibrated it without android running,generating a pointercal file.But it still didn't work. Here are my debug info: # logcat *:E E/MountListener( 527): Failed to connect to vold E/MountListener( 527): java.lang.IllegalStateException E/MountListener( 527): at com.android.server.MountListener.listenToSocket(MountListener.java: 254) E/MountListener( 527): at com.android.server.MountListener.run (MountListener.java:274) E/MountListener( 527): at java.lang.Thread.run(Thread.java: 1060) E/MountListener( 527): Failed to connect to vold # ls /dev/input event0 event1 ts0 # cat /proc/bus/input/devices I: Bus=0019 Vendor=0001 Product=0001 Version=0001 N: Name="s3c-keypad" P: Phys=s3c-keypad/input0 S: Sysfs=/devices/platform/s3c-keypad/input/input0 U: Uniq= H: Handlers=kbd event0 B: EV=100003 B: KEY=1fffe I: Bus=0013 Vendor=dead Product=beef Version=0101 N: Name="S3C TouchScreen" P: Phys=input(ts) S: Sysfs=/devices/virtual/input/input1 U: Uniq= H: Handlers=event1 ts0 B: EV=b B: KEY=20 0 0 0 0 0 0 0 0 0 0 B: ABS=1000003 # cat /proc/bus/input/handlers N: Number=0 Name=kbd N: Number=1 Name=evdev Minor=64 N: Number=2 Name=tsdev Minor=128 What is the difference btw event1 and ts0? and my env for tslib are: export TSLIB_TSEVENTTYPE INPUT export TSLIB_CONSOLEDEVICE none export TSLIB_FBDEVICE /dev/graphics/fb0 export TSLIB_TSDEVICE /dev/input/event1 //I had tried ts0,still the same export TSLIB_CALIBFILE /system/etc/pointercal export TSLIB_CONFFILE /system/etc/tslib/ts.conf export TSLIB_PLUGINDIR /system/lib/ts # getevent tsdev (compaq touchscreen emulation) is scheduled for removal.
