QT移植完，界面像死机一样停在那儿

QT移植完之后，一直停留在Welcome to Qtopia启动界面，不能校正触摸，光标也停留在那不能动
用天嵌自带的zImage,和root烧写完，我看了一下目录
[root@EmbedSky /]# ls sys/devices/              
platform  system    virtual
[root@EmbedSky /]# ls sys/devices/virtual/      
bdi        graphics   mem        mtd        sound      vc
block      input      misc       net        tty        vtconsole
[root@EmbedSky /]# ls sys/devices/virtual/input
input0  mice
[root@EmbedSky /]# ls sys/devices/virtual/input/input0
capabilities  id            name          subsystem     uniq
event0        modalias      phys          uevent


[root@EmbedSky /]# ls etc
boa                inetd.conf         nettype.conf       sysconfig
fstab              init.d             passwd             tq2440_serial.cfg
ftpchroot          inittab            profile            ts.conf
ftpusers           login.defs         protocols          wifi.conf
group              mdev.conf          rc.d
host.conf          mime.types         resolv.conf
hosts              net.conf           services

可见qtopia执行文件if [ -f /sys/devices/virtual/input/input0/uevent ] 应该满足，而if [ -f etc/pointercal ]应该不满足，但是我的自己做的zImage和root烧写完是这样的
[root@EmbedSky /]# ls sys/devices
isa       platform  system
/sys/devices/下没有生成virtual目录，这是怎么回事呢？

[root@EmbedSky /]# ls etc
boa                 net.conf            resolv.conf~
fstab               net.conf~           shadow
group               passwd              sysconfig
init.d              pointercal          tq2440_serial.cfg
inittab             profile             tq2440_serial.cfg~
inittab~            profile~            ts.conf
mdev.conf           rc.d                ts.conf~
mdev.conf~          resolv.conf
居然有pointercal，可见满足了第二个if条件，自然qtopia中的ts_calibrate不会执行了，怎么会有的呢，为什么天嵌自带的不会生成呢？？

输入 cat /dev/event0 | hexdump，看了一下触摸驱动，看了一下有反应
[root@EmbedSky /]# cat /dev/event0 | hexdump

# cd /sys
# find -name uevent
找到了
./class/input/input0/uevent
./class/input/input0/event0/uevent
我试着将if [ -f /sys/devices/virtual/input/input0/uevent ] 中的条件改为/class/input/input0/uevent，但是没啥改善
