问题1.我安装了skyeye-0.4.7-rh9.0.bin并改名和属性后;再安装arm-elf-toos-20030314.sh;再解压uClinux-dist-20020927.tar.gz,make menuconfig后出现选择画面，但我无法进行选择，按任何键都不起作用，只能退出。请问怎么做？

You can try 'make xconfig' command and check the privilege, whether you have privilege to configure the kernel?

我刚开始用的uclinux-dist-20030909.tar.gz时遇到这个问题，后来我用uclinux-dist-20051110.tar.gz就可以了；现有另外一个问题：出现skyeye Amulator画面后，我执行target sim时报错，意思是我的SKYEYE.CONF有错误，文件内容如下：

jellycn:你有编译好的ucosii for skyeye(ucosii4skyeye-binary-v1.8tgz)吗？
因为我使用源码时，然後编译但没有*.elf file.

3Q!

wanh17,Plz show me the error message.You can refer to my article about SkyEye Installation Notes. My configure files is following:

You can copy to the uClinux-dist diretory, and run 'skyeye -e linux-2.4.x/linux' command.

3Q!Jellycn,i will try it again.

the error message is:
(skyeye)target sim
cpu info:arm3,arm7tdmi,4100700,fff8ff00,0
mach info:name at91,mach_init addr 0x813dae4
unknow option file=images/romf.img
skyeye_read_config:config file skyeye.conf have errors!

my QQ:53167312

You can install the latest version of SkyEye(skyeye-1.2.0-RC7-2) or refer to the README files in skyeye-0.4.7 source code directory, how to write skyeye.conf file.I suggest you install the latest version of SkyEye.

现在有另一个错误：

Oh~I think your configure file is incorrect, you can check it. Whether the range of IO is wrong?

I don't known why don't you try the latest version of SkyEye?

感谢JELLYCN的帮助以及参照网上的帖子，UCLINUX终于可以在SKYEYE上运行了 :-) ，以后的路还很长，   。总结一下这几天的心得，贴上来共大家分享。高手就不用看了。

琢磨SKYEYE已有一个礼拜了，今天早上终于可以在SKYEYE上运行出UCLINUX初始画面；小有成就感，呵呵：） 总结一下这几天的心得：

1.在REDHAT9.0上安装SKYEYE：

  我开始在网上下载SKYEYE的源代码进行编译和安装，不成功：（

  干脆直接下载编译好的SKYEYE(SKYEYE-0.4.7-RH9.0.BIN)，移动到/USR/LOCAL/BIN下，并改名为SKYEYE，改变SKYEYE的使用权限：

   MV SKYEYE-0.4.7-RH9.0.BIN /USR/LOCAL/BIN/SKYEYE

   CHMOD 755 /USR/LOCAL/BIN/SKYEYE

2.安装ARM-ELF交叉编译器（用于编译UCOSII4SKYEYE和UCLINUX4SKYEYE）:

   下载ARM-ELF-TOOLS-20030314.SH，改变权限并执行:

   CHMOD 755 ARM-ELF-TOOLS-20030314.SH

   ./ARM-ELF-TOOLS-20030314.SH 结束后，ARM-ELF-GCC/GDB....工具会安装到/USR/LOCAL/BIN下。

3.安装 UCOSII FOR SKYEYE:

  下载UCOSII4SKYEYE-1.9.3.TAR.GZ，解压TAR -ZVXF UCOSII4SKYEYE-1.9.3.TAR.GZ 进入解压后的目录，制定编译器：

  export CROSS_COMPILE="/USR/LOCAL/BIN/ARM-ELF-"

  修改LIB/SKYEYE_PRINTF.C文件（使用VI编辑器来做）：

     加入:

    static int isdigit(char ch)

    { if (ch>='0'&&ch<='9')

       return 1;

       return 0;

    }

    然后吧该文件中的“#include”这行注释掉，保存并退出。

   cd ucosii4skyeye/samples/ucos_test

   make cleanall

   make config

   make

   make test

  执行这步后会生成很多文件，包括ucos_test.elf文件。 执行/usr/local/bin/skyeye/skyeye后出现SKYEYE 调试画面，进入SKYEYE后：

  target sim

  load ucos_test.elf

  run
  
it's ok!

4.运行最简单的应用程序HELLO4SKYEYE.TGZ:

   解压：TAR -ZXVF HELLO4SKYEYE.TGZ，进入生成的目录：

   CD HELLO4SKYEYE， MAKE后，启动SKYEYE:/USR/LOCAL/BIN/SKYEYE/SKYEYE，

   TARGET SIM，

   LOAD HELLO，

   RUN。 如果改变HELLO.C中的内容后（VI编辑器），然后MAKE HELLO才能最终改变输出结果。

5.安装UCLINUX:

  下载UCLINUX-DIST-20020927.TAR.GZ(我第一次用2005版的，运行到最后不能执行，改用2002版的？？)， 解压TAR ZXF UCLINUX-DIST-20020927.TAR.GZ

   CD UCLINUX-DIST

  在命令行方式下执行 MAKE MENUCONFIG(我的LINUX不能执行MAKE XCONFIG ??)，在VENDOR/PRODUCT中选择GDB/ARMULATOR，KERNEL版本选择2.4，SAVE AND EXIT。

  MAKE DEP

  MAKE

  在/USR/LOCAL/SKYEYE/UCLINUXSOURCE/UCLINUX-DIST/IMAGES/下生成文件ROMFS.IMG，在/USR/LOCAL/SKYEYE/UCLINUXSOURCE/UCLINUX-DIST/LINUX-2.4.X下生成一个LINUX文件（没有后缀名？？）。

  在/USR/LOCAL/SKYEYE/UCLINUXSOURCE/UCLINUX-DIST/下新建一个SKYEYE.CONF文件：

  CPU:ARM7TDMI

  MACH:AT91

  mem_bank:map=M,type=RW,addr=0x00000000,size=0x00004000

  mem_bank:map=M,type=RW,addr=0x01000000,size=0x00400000

   mem_bank:map=M,type=R,addr=0x01400000,size=0x00400000,file=images/romfs.img

  mem_bank:map=M,type=RW,addr=0x02000000,size=0x00400000

  mem_bank:map=M,type=RW,addr=0x02400000,size=0x00008000

  mem_bank:map=M,type=RW,addr=0x04000000,size=0x00400000

  mem_bank:map=I,type=RW,addr=0xf0000000,size=0x10000000

  net:state=on,mac=0:4:3:2:1:f,ethmod=tun,hostip=10.0.0.1

执行SKYEYE:/usr/local/bin/skyeye/skyeye linux-2.4.x/linux

target sim

load

run

就这样了。

Congratulation~~~
