运行环境：Redhat9.0+skyeye0.7.0+arm-elf-gcc+uClinux20030522(附带uclinux4skyeye-v0.2.3)
首先安装skyeye0.7.0和交叉编译环境,
然后将uclinux4skyeye解压，按照installguide.txt中的提示将文件拷贝
到uClinux-dist的相应目录中，
进行make menuconfig,网络功能选项中会出现skyeye支持的选项，
接下来make dep,make 完成安装。
加入网络功能：看看是否tun.o存在,其是linux内核带的一个模拟网络点到点的虚拟网络设备,
不存在就：
mknod /dev/net/tun c 10 200
insmod /lib/modules/2.4.x/kernel/drivers/net/tun.o
可以了。
skyeye.conf 应该是
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=RW, addr=0x04000000, size=0x00400000
mem_bank: map=I, type=RW, addr=0xf0000000, size=0x10000000
# format: state=on/off mac=xx:xx:xx:xx:xx:xx ethmod=tuntap/vnet hostip=dd.dd.dd.dd
net: state=on, mac=0:4:3:2:1:f, ethmod=tun, hostip=10.0.0.1
如果uClinux正常运行，出现
Command: hostname GDB-ARMulator
Command: /bin/expand /etc/ramfs.img /dev/ram0
Command: mount -t proc proc /proc
mount: /etc/mtab: Read-only file system

我的Redhat9.0主机-->[eth0:192.168.5.10]
-->[tap0:10.0.0.1]
uClinux-->[10.0.0.2]
在uClinux的路由表中加入 destination 192.168.5.0 nexthop 10.0.0.1
即可完成两端的通讯功能！其他网段通讯类似处理！
测试通过！
