在ubuntu上搭建uClinux编译开发环境并用Skyeye (2)

四、测试这个程序：

测试这个程序需要用到一个工具skyeye-testsuits，可以在下面的网址下载：
http://gro.clinux.org/projects/skyeye/
网址里面有testsuite2.1.tar.bz2 但是在这里我们直接下载1.2.0版的二进制的工具包，skyeye-binary-testutils-1.2.0.tar.bz2
下载后解压

代码:

wenwu@wenwu-desktop:/source$ tar jxvf skyeye-binary-testutils-1.2.0.tar.bz2

进入下面这个目录，这是我们主要用到的目录。

代码:

wenwu@wenwu-desktop:/source$ ls skyeye-binary-testutils-1.2.0/at91x40/uclinux2 boot.rom  linux  readme  skyeye.conf

这个目录里面有四个文件，其中linux就是内核映像，boot.rom是要写到Flash里面去的。里面包含文件系统。skyeye.conf是配置文件。
可以在命令行里键入以下代码，

代码:

skyeye -e linux

你看到了什么？没错，我没有骗你

代码:

____ _  _          /  __| ||_|                      _   _| |  | | _ ____  _   _  _  _    | | | | |  | || |  _ /| | | |/ // /    | |_| | |__| || | | | | |_| |/    /    |  ___/____|_||_|_| |_|/____|/_//_/    | |    |_|

当你看到这幅图片的时候，是不是感觉很爽？呵呵，我也是。

刚才我们不是写了一个代码吗？下面我们就看看怎么运行我们的程序：
首先在skyeye-binary-testutils-1.2.0/at91x40/uclinux2这个目录里面建立一个文件夹：romfs
这个目录主要用来存放用户程序，就是最后你写的程序也要拷到这个目录里面。

代码:

wenwu@wenwu-desktop:/source/skyeye-binary-testutils-1.2.0/at91x40/uclinux2$ mkdir romfs wenwu@wenwu-desktop:/source/skyeye-binary-testutils-1.2.0/at91x40/uclinux2$ ls boot.rom  linux  readme  romfs  skyeye.conf

但是我们必须把系统已有的文件系统里面的程序也拷出来，也就是把boot.rom本身所有的程序也要拷到romfs这个文件夹里面，所以首先要进行一次挂载，所以进入/mnt目录，建立一个临时文件夹tmp,如下所示

代码:

wenwu@wenwu-desktop:/mnt$ ls wenwu@wenwu-desktop:/mnt$ sudo mkdir tmp wenwu@wenwu-desktop:/mnt$ ls tmp

用 mount -o loop src dst命令进行挂载，如下所示：

代码:

wenwu@wenwu-desktop:/source/skyeye-binary-testutils-1.2.0/at91x40/uclinux2$ sudo mount -o loop boot.rom /mnt/tmp/ wenwu@wenwu-desktop:/source/skyeye-binary-testutils-1.2.0/at91x40/uclinux2$ ls /mnt/tmp/ bin  dev  etc  home  lib  mnt  proc  sbin  tmp  usr  var

然后把这里面的所有文件拷贝到我们刚才所建的那个我们自己的文件夹romfs里面

代码:

wenwu@wenwu-desktop:/source/skyeye-binary-testutils-1.2.0/at91x40/uclinux2$ sudo cp -r /mnt/tmp/* ./romfs/

这时，我们自己的文件夹里面有以下内容：

代码:

wenwu@wenwu-desktop:/source/skyeye-binary-testutils-1.2.0/at91x40/uclinux2$ ls romfs/ bin  dev  etc  home  lib  mnt  proc  sbin  tmp  usr  var

将我们刚才生成的一个测试程序test也拷贝过来到romfs/bin目录时面：

代码:

wenwu@wenwu-desktop:/source/skyeye-binary-testutils-1.2.0/at91x40/uclinux2$ sudo cp /source/work/test/test romfs/bin/ wenwu@wenwu-desktop:/source/skyeye-binary-testutils-1.2.0/at91x40/uclinux2$ ls romfs/bin/ boa      dhcpcd  ftp   gdbserver  inetd  login  ping    route  telnet   test busybox  expand  ftpd  ifconfig   init   mount  reboot  sh     telnetd  umount

用genromfs这个工具重新制作文件系统

代码:

wenwu@wenwu-desktop:/source/skyeye-binary-testutils-1.2.0/at91x40/uclinux2$ sudo genromfs -f boot.rom -d ./romfs/ wenwu@wenwu-desktop:/source/skyeye-binary-testutils-1.2.0/at91x40/uclinux2$ ls -l boot.rom -rw-r--r-- 1 wenwu wenwu 1561600 2007-11-11 14:03 boot.rom

好了，下面我们再运行skyeye进行仿真，键入：skyeye -e linux

代码:

在这里面进行以下操作：

代码:

/> cd bin /bin> ./test i=0 Hello,embedded linux! i=1 Hello,embedded linux! i=2 Hello,embedded linux! i=3 Hello,embedded linux! i=4 Hello,embedded linux! i=5 Hello,embedded linux! /bin>

看到程序在运行了吗？
