我在linux 2.6.38内核上移植触摸屏的驱动，因为对这部分不熟悉，直接拷贝开发板光盘上自带的文件系统中qtopia和ts_calibrate等文件到我自己的需要做的文件系统中，但是系统提示找不到。
还有rx.sz.rz等命令也提示找不到，但是我的文件系统中确认存在，请大侠帮忙解决。
非常感谢~

其中backlight、ts_calibrate、madplay几个都不行，是可执行的，但是没有link to busybox
该怎么解决。

可能是版本不对

回答：文件系统中没有 ts_calibrate校准程序
还有rx.sz.rz等命令也提示找不到，但是我的文件系统中确认存在，请大侠帮忙解决。
回答：找不到你看看有没有这些工具命令在文件系统中

谢谢你们的回复，但是我非常肯定我说的那些命令都是存在的，我是从光盘中自带的文件系统中拷贝过来的。
上面只列出了sbin目录下文件，其中是有ts_calibrate，你可能没有看清楚，
另外rx,rz等都在usr/bin下面，我没有列出来。

以上还请帮忙分析原因，非常感谢~

有可能：
1，你拷贝过来时候已经失去了可执行属性
2. 你自己的文件系统所利用的交叉编译器和我们的不一样

谢谢~
那些源代码从哪儿可以找到，我自己编译做文件系统。
另外问一下，是不是静态编译的那些执行文件不会存在这样的问题？

ts_calibrate在光盘提供的 TQ2440_CD\Linux资源\Qt源码包\Qte_20100601.tar.bz2
文件中的 tslib源码中
rz sz 是另外下载源码的，你查找一下是可以知道的
