Qtopia 2.2.0下触摸屏无法使用的问题

使用的linux是2.6.25.8,根据TQ的一步一步移植手册移植好的，触摸屏驱动也是直接从TQ提供的源码里复制出来的
然后Qtopia2.2.0也是TQ提供的，编译出来。。。结果，总是无法进入矫正界面，更无法使用（鼠标使用到时正常）

我直接执行（我想试试这样能否进入矫正）
[root@EmbedSky /]# ts_calibrate
ts_open: No such file or directory
还没明白ts_open在哪里呢，看了驱动里也没找到。。。

在bin下写的Qtopia是这样的
export set HOME=/root
export set QTDIR=/opt/Qtopia
export set QPEDIR=/opt/Qtopia
export set KDEDIR=/opt/kde
export set QWS_KEYBOARD="TTY:/dev/tty1"
if [ -f /sys/devices/virtual/input/input0/uevent ];then
        export set TSLIB_TSDEVICE=/dev/event0
        export set TSLIB_CONFFILE=/etc/ts.conf
        export set TSLIB_PLUGINDIR=/lib/ts
        export set TSLIB_CALIBFILE=/etc/pointercal
        export set QWS_MOUSE_PROTO="TPanel:/dev/event0 USB:/dev/mouse0"
else
        export set QWS_MOUSE_PROTO="USB:/dev/mouse0"
        if [ - /etc/pointercal ];then
                echo only use mouse > tq2440_serial0
        else
                echo "1 0 1 0 1 1 65536" > /etc/pointercal
       fi
fi
export set PATH=$QPEDIR/bin:$PATH                                      
export set LD_LIBRARY_PATH=$QTDIR/lib:$QPEDIR/lib                     
                                                           
if [ -f /etc/pointercal ];then                             
        qpe 1>/dev/null 2>/dev/null                        
else                                                      
        ts_calibrate                                       
        qpe 1>/dev/null 2>/dev/null                        
                                                
fi

每次启动，这个条件都无法成立if [ -f /sys/devices/virtual/input/input0/uevent ];then
但是在启动信息中又看到驱动安装成功了吖。。。是不是在2.6.25.8版本的linux下地址会不一样呢？

不知道肿么办，为什么光盘只提供了2.6.30版本的文件系统源码，而没有2.6.25的。。。

顺便提下开发板是TQ2440

刚才试了下把Qropia注释成这样
#if [ -f /sys/devices/virtual/input/input0/uevent ];then
        export set TSLIB_TSDEVICE=/dev/event0
        export set TSLIB_CONFFILE=/etc/ts.conf
        export set TSLIB_PLUGINDIR=/lib/ts
        export set TSLIB_CALIBFILE=/etc/pointercal
        export set QWS_MOUSE_PROTO="TPanel:/dev/event0 USB:/dev/mouse0"
#else
#       export set QWS_MOUSE_PROTO="USB:/dev/mouse0"
#       if [ - /etc/pointercal ];then
  #              echo only use mouse > tq2440_serial0
  #      else
#               echo "1 0 1 0 1 1 65536" > /etc/pointercal
  #     fi
#fi

幻想着让他强制进入有触摸驱动下。。。结果开机后提示
Start Qtopia-2.2.0

什么段错误？不知道神马意思呵呵。。。

删除pointercal 这个文件，启动后就调用你的触屏校验程序了

ts_open应该是你驱动有问题，看看是否加载触屏驱动

  export set TSLIB_TSDEVICE=/dev/event0这句话中的event0一定要是触摸设备的设备名哦。
/sys/devices/virtual/input/input0/uevent这句话是判断是否存在触摸设备（如果不存在，就执行else的。）
你的触摸设备名是什么呢？

谢谢回答，这个启动信息能否说明加载成功了呢？

:$有点不好意思，我还不知道怎么查看触摸设备的设备名呢。。。

文件EmbedSky_ts.c驱动里的
static struct device_driver EmbedSky_ts_driver = {
       .name           = "EmbedSky-ts",
       .bus            = &platform_bus_type,
       .probe          = EmbedSky_ts_probe,
       .remove         = EmbedSky_ts_remove,
};

tsdev.c驱动里的
static struct input_handler tsdev_handler = {
        .event                = tsdev_event,
        .connect        = tsdev_connect,
        .disconnect        = tsdev_disconnect,
        .fops                = &tsdev_fops,
        .minor                = TSDEV_MINOR_BASE,
        .name                = "tsdev",
        .id_table        = tsdev_ids,
};
这两个的.name和设备名有没有关系呢？

谢谢亚瑟老大

根据你的信息，显示环境变量中TSLIB相关的都没有生效哦。
根据你在10楼给出来的信息显示event0就是触摸设备的设备名，那么/sys/devices/virtual/input/input0/uevent就应该存在。但是条件执行语句却判断出来event0不存在，所以确认一下/sys/devices/virtual/input/input1/uevent 文件是否存在吧。
