设置qtopia4运行的环境变量，脚本/bin/qtopia4内容如下：
#!/bin/sh
export TSLIB_TSDEVICE=/dev/input/event0
export TSLIB_CONFFILE=/usr/local/etc/ts.conf
export TSLIB_PLUGINDIR=/usr/local/lib/ts
export TSLIB_CALIBFILE=/etc/pointercal
export QPEDIR=/home/abilly/qtopia4_arm/target-arm
export PATH=$QPEDIR/bin:$PATH
export LD_LIBRARY_PATH=$QPEDIR/lib:/usr/local/lib:$LD_LIBRARY_PATH
export QWS_SIZE=240x320
export HOME=/home/abilly/qtopia4_arm
export QWS_DISPLAY="LinuxFB:/dev/fb0"
export QWS_DISPLAY="LinuxFB:mmWidth130:mmHeight100:0"
export QWS_KEYBOARD=TTY:/dev/tty1
export QWS_MOUSE_PROTO="TSLIB:/dev/input/event0"
export QT_PLUGIN_PATH=$QPEDIR/plugins/
export QT_QWS_FONTDIR=$QPEDIR/lib/fonts/
修改rcS运行qtopia4的qpe
#/bin/qtopia &
#echo " " > /dev/tty1
#echo "Starting Qtopia, please waiting..." > /dev/tty1
source /bin/qtopia4
if [ -f /etc/pointercal ]; then
$QPEDIR/bin/qpe -qws &
else
/usr/loca/bin/ts_calibrate
$QPEDIR/bin/qpe -qws &
Fi
Nfs 文件系统的挂载略。
启动开发板，结果如图：
对于字体大小，图标大小，应用程序的编译与添加有待研究。
能解释一下这里么 这里有点不明白
