按照陈渝老师光盘里的readme文件说的模拟开发板上的网卡咋ping不通呢？希望得到大家的
我现在把遇到问题整理出来,希望得到指点：
skyeye模拟开发板上网卡的思想是在主机上模拟一个网卡10.0.0.1
在模拟的开发板上模拟一个网卡10.0.0.2
然后是10.0.0.2与10.0.0.1之间进行模拟的数据交换。
现在遇到的问题具体如下：
1：进入skyeye环境后提示:
Command: /bin/ifconfig eth0 up 10.0.0.2
SIOCGIFFLAGS: No such device
SIOCSIFADDR: No such device
pid 12: failed 512
说明模拟的开发板上的网卡有问题。
2:在skyeye环境下ping不通主机的IP地址10.0.0.1
3:在skyeye环境下ping不通模拟开发板上的模拟网卡的IP地址10.0.0.2
4:在主机环境下可以ping通与模拟的开发板通讯的主机的网卡IP地址10.0.0.1
我买了陈渝所编《源码开放的嵌入式系统软件分析与实践--基于SkyEye和ARM开发平台》的书及光盘
假设已经把光盘里的内容copy到/opt/skyeye-cdrom/目录下
因为光盘里没有uClinux-dist-20030522-tar.gz文件，我是从
http://www.uclinux.org/pub/uclin ... .tar.gz下载的。
copy文件uClinux-dist-20030522-tar.gz到/opt/skyeye-cdrom/uClinux/目录下.
第0步：#cd /opt/skyeye-cdrom/SkyEye/testsuit/
#tar jxfv skyeye-binary-testutils-1.0.7.1.tar.bz2
第一步：建立交叉编译环境
（1）为编译uclinux建立交叉编译环境
#cd /opt/skyeye-cdrom/DevelopTools/uClinux_gnutools/arm/
#sh arm-elf-tools-20030314.sh
#ls /usr/local/bin/arm-elf-* (可以看到arm-elf-gcc等编译工具已经安装到您的机器上)
（2）为编译armlinux建立交叉编译环境
1）安装3.3.2版本
#cd /opt/skyeye-cdrom/DevelopTools/ARMlinux_gnutools/arm/
#cp arm-linux-gcc-3.3.2.tar.bz2 /
#cd /
#tar jxfv arm-linux-gcc-3.3.2.tar.bz2
#ls /usr/local/arm/3.3.2/bin/arm-linux-* (可以看到3.3.2版本的arm-linux-gcc等编译工具已经到您的机器上)
1）安装2.95.3版本
#cd /opt/skyeye-cdrom/DevelopTools/ARMlinux_gnutools/arm/
#cp cross-2.95.3.tar.bz2 /usr/local/arm/
#cd /usr/local/arm/
#tar jxfv cross-2.95.3.tar.bz2
#ls /usr/local/arm/2.95.3/bin/arm-linux-* (可以看到2.95.3版本的arm-linux-gcc等编译工具已经到您的机器上)
第二步：编译安装skyeye
#cd /opt/skyeye-cdrom/SkyEye/skyeye/
#tar jxfv skyeye-0.8.0.tar.bz2
#cd skyeye
#./configure --target=arm-elf --prefix=/usr/local
#make
#make install
#skyeye（现在就可以在任何路径下运行skyeye了，键入quit退出skyeye）
第三步：编译带有网络支持的嵌入式操作系统--uclinux
#cd /opt/skyeye-cdrom/uClinux
#tar zxf uClinux-dist-20030522.tar.gz
#cp /opt/skyeye-cdrom/SkyEye/uclinux4skyeye/uclinux4skyeye-v0.2.3.tgz .
#tar zxf uclinux4skyeye-v0.2.3.tgz
#cd uclinux4skyeye
#cp example/uclinux-dist-20030522/vendors__GDB__ARMulator/* ../uClinux-dist/vendors/GDB/ARMulator/
#cd /opt/skyeye-cdrom/uClinux/uClinux-dist
#mkdir drivers
#cd drivers
#mkdir net
#cd /opt/skyeye-cdrom/uClinux/uclinux4skyeye
#cp example/uclinux-dist-20030522/linux-2.4.x__drivers__net/* ../uClinux-dist/drivers/net/
#cd ..
#cd uClinux-dist
#make menuconfig(若是在X window上，终端窗口的尺寸必须大于19行80列，否则Menuconfig无法正常运行)
