    3 下载文件
    1> skyeye 最新版
    wget http://jaist.dl.sourceforge.net/ ... ye-1.2.4_Rel.tar.gz

    2> arm开发环境
          有了这个就可以在ubuntu下编译arm上可以用的软件了，就一个包安装了就ok了，当然如果你不怕麻烦或者想自己做一个环境出来也是可以的，那就自己学一下怎么搭建交叉编译环境吧
    wget http://opensrc.sec.samsung.com/d ... s-20040427.sh%C2%A0
    3> 如果要测试你的环境是不是ok了，是不是可以正常的使用skyeye来模拟arm开发板，那么下面的软件是必须的
    http://nchc.dl.sourceforge.net/s ... stsuite-2.3.tar.bz2
    4> 我们要安装uClinux 那么这个包就必须下下来
    http://www.uclinux.org/pub/uClin ... est-20070823.tar.gz
    二//----------------------------------------------------------------------------------------------------------------------------------
    安装arm tool
    [email=root@ubuntu:~/cache]root@ubuntu:~/cache[/email]# mv arm-elf-tools-20040427.sh_ arm-elf-tools-20040427.sh
    [email=root@ubuntu:~/cache]root@ubuntu:~/cache[/email]# chmod 755 arm-elf-tools-20040427.sh

    查看了以后，安装一ok了，我们现在测试一下是不是真的ok了，nano建立一个文件
    [email=root@ubuntu:~/cache]root@ubuntu:~/cache[/email]# nano test.c
    然后输入
    #include <stdio.h>
    int main()
    {
            printf("ARM tools is OK\n");
            return 0;
    }
    然后ctrl+o保存退出
    我们编译出来这个测试文件
    [email=root@ubuntu:~/cache]root@ubuntu:~/cache[/email]# arm-elf-gcc -Wl,-elf2flt -o test test.c
    看清楚了，W后面的是个小写的L，不是数字1哦
    然后我们查看一下是不是编译ok了
    [email=root@ubuntu:~/cache]root@ubuntu:~/cache[/email]# ls -lh test*
    -rwxr--r-- 1 root root 29K Dec 14 12:45 test
    -rw-r--r-- 1 root root 136 Dec 14 10:38 test.c
    -rwxr-xr-x 1 root root 76K Dec 14 12:45 test.gdb
    [email=root@ubuntu:~/cache]root@ubuntu:~/cache[/email]# file test
    test: BFLT executable - version 4 ram
    [email=root@ubuntu:~/cache]root@ubuntu:~/cache[/email]# file test.gdb
    test.gdb: ELF 32-bit LSB executable, ARM, version 1, statically linked, not stripped
    我们运行一test看看，呵呵，肯定出错，出错也看看
    [email=root@ubuntu:~/cache]root@ubuntu:~/cache[/email]# ./test
    bash: ./test: cannot execute binary file
    在arm下跑的肯定不能x86下跑了
    我们继续

    安装skyeye
    1> 解压缩
    [email=root@ubuntu:~/cache]root@ubuntu:~/cache[/email]# cd /usr/local/;tar zxvf /root/cache/skyeye-1.2.4_Rel.tar.gz

    skyeye-1.2.4/binary/README
    修改个名字，skyeye
    [email=root@ubuntu:/usr/local]root@ubuntu:/usr/local[/email]# mv skyeye-1.2.4/ skyeye
    [email=root@ubuntu:/usr/local]root@ubuntu:/usr/local[/email]# cd skyeye/

    COPYING    LICENSE      Makefile  REPORTING-BUGS  arch    dbct    misc
    ChangeLog  MAINTAINERS  README    TODO            binary  device  utils
    2> make一下看
    [email=root@ubuntu:/usr/local/skyeye]root@ubuntu:/usr/local/skyeye[/email]# make
    --------------------------- NOTICE ------------------------------
    If you always get error, please run "make NO_CHECK=1" instead.
    -----------------------------------------------------------------
    Checking whether host is big endian ... no
    Checking gcc ... OK ( gcc version: 4.1.3 )
    Checking whether the compiler supports x86 asm ... FAILED
    *** It seems that the compiler don't support inline x86 AT&T ASM codes.
    *** Run "make NO_DBCT=1" instead to ignore it.
    make: *** [check] Error 1
    重新按照下面的输入重新make
    [email=root@ubuntu:/usr/local/skyeye]root@ubuntu:/usr/local/skyeye[/email]# make clean
    [email=root@ubuntu:/usr/local/skyeye]root@ubuntu:/usr/local/skyeye[/email]# make NO_DBCT=1
    耐心等待一下，我的计算机大概两分钟就ok了，直到下面的出现就表示ok了
    ****
    **** The binary file located at 'binary/skyeye', enjoy it.
    ****
    然后我们编辑一下环境变量，把path修改一下，让系统能直接找到skyeye
    [email=root@ubuntu:/usr/local/skyeye]root@ubuntu:/usr/local/skyeye[/email]# nano /etc/environment
    看第一行
    PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/skyeye/binary"
    修改如上面的这样，然后保存--按快捷键 Ctrl+o，然后打回车
    然后exit退出到登陆界面重新登陆一下，让刚才修改的生效
    我们测试一下看ok了没
    [email=root@ubuntu:/]root@ubuntu:/[/email]# skyeye -h
    ------------------------- SkyEye -V1.2 ---------------------------
    Usage: SkyEye [options] -e program [program args]
    Default mode is STANDALONE mode
    ------------------------------------------------------------------
    Options:
    -e exec-file        the (ELF executable format)kernel file name.
    -l load_address,load_address_mask
                        Load ELF file to another address, not its entry.
    -b                  specify the data type is big endian when non "-e" option.
    -d                  in GDB Server mode (can be connected by GDB).
    -c config-file      the skyeye configure file name.
    -h                  The SkyEye command options, and ARCHs and CPUs simulated.

    at91
    lpc
    s3c4510b
    s3c44b0x
    出现了这个界面说明skyeye已经ok了

    我们测试一下看看

    OK我们进到具体的目录了，我们现在测试一下看能不能把基本的测试跑起来
    运行下面的命令

    简单的说一下，-e表示指定加载什么文件为内核，-c表示什么文件是配置文件
    好，我们看一下
    [email=root@ubuntu:~/cache/skyeye-testsuite-2.3/linux/ep9312/2.6.x]root@ubuntu:~/cache/skyeye-testsuite-2.3/linux/ep9312/2.6.x[/email]# skyeye -e vmlinux -c skyeye.conf
