我按照“快速上手”重新烧录了1月6号的nand中的的uboot、内核还有文件系统。

Qtopia烧录后，就重新启动，发生了下面的情况：

删掉qpe.conf的方式也不管用。

条件export 什么的，那些路径也不管用。

组后，从uboot启动，有一个boot qtopia的选项。

然后跟直接从内核启动一样的过程，但是可以顺利看到企鹅了，应该是启动了qvfb，也就能进去图形界面了。

后来启动都是正常的了。

我真是百思不得其解。

=====

还有，内部有个qt4的测试程序，里头有个调整触摸屏的，虽然也是重启，启动测试程序，和uboot里头的启动测试程序的方式一样，

但是，这个调整过后，如果调整错了，比如我点错了，在用uboot的调整，就是调不过来。只好，努力用这个程序，再次调整一次。

虽然看上去，和uboot里的程序调整一样。

难道是配置文件的存放位置不同么？

好奇怪啊。

=======================

usb的鼠标能识别，但不能用。

下面是正常启动qtopia的过程和成功再次调整touchscreen的过程。
