求教armsys6410触摸屏移植

wgetfree

将内核3.0.1移植到armsys6410中，感觉触摸屏驱动应该搞定了：输入命令：

# cat /proc/bus/input/devices
I: Bus=0013 Vendor=dead Product=beef Version=0101
N: Name="S3C TouchScreen"
P: Phys=input(ts)
S: Sysfs=/devices/virtual/input/input0
U: Uniq=
H: Handlers=mouse0 event0  
B: PROP=0
B: EV=b
B: KEY=400 0 0 0 0 0 0 0 0 0 0
B: ABS=1000003

同时cat /dev/input/event0，点击触摸屏，是有反应的，tslib使用的是原来自带的版
本，但运行ts_calibrate报错：
./ts_calibrate  
xres = 640, yres = 480
selected device is not a touchscreen I understand
Took 4 samples...
Top left : X =    0 Y =    1
Took 4 samples...
Top right : X =    0 Y =    1
Took 4 samples...
Bot right : X =    0 Y =    1
Took 4 samples...
Bot left : X =    0 Y =    1
Took 4 samples...
Center : X =    0 Y =    1
ts_calibrate: determinant is too small -- 0.000000
Calibration failed.

tslib环境配置脚本如下：
#!/bin/sh
TSLIB_TSDEVICE=/dev/input/event0
export TSLIB_ROOT=/usr/local
TSLIB_CONFFILE=$TSLIB_ROOT/etc/ts.conf
export TSLIB_TSDEVICE
export TSLIB_CONFFILE
export TSLIB_PLUGINDIR=$TSLIB_ROOT/lib/ts
export TSLIB_CALIBFILE=/etc/pointercal
export QWS_DISPLAY=:1
export LD_LIBRARY_PATH=/usr/local/libLD_LIBRARY_PATH
export PATH=/bin:/sbin:/usr/bin/:/usr/sbin:/usr/local/bin

#TS_INFO_FILE=/sys/devices/platform/uevent
TS_INFO_FILE=/sys/devices/virtual/input/input0/uevent
if [ -e $TS_INFO_FILE -a "/bin/grep -q TouchScreen < $TS_INFO_FILE" ]; then
        echo "touch..."
        export QWS_MOUSE_PROTO="Tslib MouseMan:/dev/input/mice"
        if [ -e /etc/pointercal -a ! -s /etc/pointercal ] ; then
                rm /etc/pointercal
                $TSLIB_ROOT/bin/ts_calibrate
        fi
else
        echo "mouse..."
        export QWS_MOUSE_PROTO="MouseMan:/dev/input/mice"
        >/etc/pointercal
fi
unset TS_INFO_FILE

export QWS_KEYBOARD=TTY:/dev/tty1
export HOME=/root

不知道怎么回事，就是无法进行鼠标校正。
