hi,weber I got the same problem as you. It was some thing wrong with your screen driver. Maybe in your Framebuffer driver. Find the PowerManagerService.java modify the following function. boolean screenIsOn() { synchronized (mLocks) { return true; // return (mPowerState & SCREEN_ON_BIT) != 0; } }
try it :-) and don't forget to fix the driver in the kernel. 2009/12/2 Michael Trimarchi <trimar...@gandalf.sssup.it> > Weber wrote: > > 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 > > > Sorry but this is unrelated to the touchscreen problem :) > Michael > > # 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. > > See Documentation/feature-removal-schedule.txt for details. > > could not get driver version for /dev/input/ts0, Invalid argument > > add device 1: /dev/input/event1 > > name: "S3C TouchScreen" > > add device 2: /dev/input/event0 > > name: "s3c-keypad" > > /dev/input/event1: 0000 0000 00000000 > > /dev/input/event1: 0003 0000 00000505 > > /dev/input/event1: 0003 0001 00000870 > > /dev/input/event1: 0003 0018 00000001 > > /dev/input/event1: 0000 0000 00000000 > > /dev/input/event1: 0003 0000 00000506 > > /dev/input/event1: 0003 0001 00000879 > > /dev/input/event1: 0000 0000 00000000 > > /dev/input/event1: 0003 0018 00000000 > > /dev/input/event1: 0000 0000 00000000 > > /dev/input/event1: 0003 0000 000006b6 > > > > and then I open the DEBUG in s3c_ts.c,when touching it,the console > > prints: > > # D > > D > > D > > T: 853507, X: 28791, Y: 31853 > > T: 878508, X: 28404, Y: 32080 > > D > > T: 603508, X: 31842, Y: 18032 > > T: 628524, X: 31689, Y: 18009 > > D > > T: 818507, X: 44988, Y: 16935 > > T: 843508, X: 44818, Y: 17687 > > T: 868506, X: 45122, Y: 17618 > > T: 893508, X: 45248, Y: 18344 > > D > > T: 648508, X: 45725, Y: 43406 > > T: 673508, X: 45500, Y: 43828 > > D > > T: 478507, X: 24101, Y: 19161 > > T: 503508, X: 23650, Y: 19044 > > T: 528508, X: 23943, Y: 18982 > > It seems that android didn't get my input coordinate but the kernel > > did > > > > and the post > > > http://groups.google.com/group/android-porting/browse_thread/thread/fb64af66b1f877fa/c72fc79b31c83dca?lnk=gst&q=Touch+Screen+%3F4%3F%3F&_done=%2Fgroup%2Fandroid-porting%2Fbrowse_thread%2Fthread%2Ffb64af66b1f877fa%2Fc72fc79b31c83dca%3Flnk%3Dgst%26q%3DTouch%2BScreen%2B%253F4%253F%253F > > says that " Power Management support "is necessary ,so I chose it > > and rebuilt ,but it still has no response . > > > > so could anyone tell me what are my problems ?and How should i do to > > make the touchscreen work? > > Thanks! > > ---Weber > > > > > > -- > unsubscribe: > android-porting+unsubscr...@googlegroups.com<android-porting%2bunsubscr...@googlegroups.com> > website: http://groups.google.com/group/android-porting > -- unsubscribe: android-porting+unsubscr...@googlegroups.com website: http://groups.google.com/group/android-porting
