skyeye qt4模拟的问题，屏幕没有任何显示

skyeye1.3.1 s3c2410qt4.6.3
frame buffer已经驱动好，echo aaaaaaaaaaa > /dev/fb0,屏幕颜色会有变化,testsuite里miniGUI的例子可以显示窗体。
执行qt例程 ./books -qws, 没有任何错误提示，但没有任何窗体出来，大概8－10分钟后出现
段错误 (core dumped)

查看core文件，错误调用如下：
#00x6d457451 in ?? ()
#10xb7f88b02 in io_do_cycle (state=0x8081da8) at bus/io.c:72

#60x47d3f832 in start_thread () from /lib/libpthread.so.0
#70x47c94e0e in clone () from /lib/libc.so.6

有哪位过了这步的请不吝赐教，谢谢！

这次定位到/opt/skyeye/lib/skyeye/liblcd.so了。

最新版的skyeye模拟最新版的qt for arm,只差最后一步，期待哪位高手能指点迷津，谢谢！

运行skyeye的终端有如下 一行LCD相关错误：
In skyeye_find_lcd_dma, probably not finished porting.
