求助：skyeye中cs8900a的基址配置问题（uclinux）

yjfgc

uclinux配置中 make xconfig （Ethernet10/100M）选择了cs8900a网卡
编译成功

然后运行skyeye.conf配置文件如下：
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

mem_bank: map=I, type=RW, addr=0xf9000300, size=0x00000020
net: state=on,type=cs8900a, base=0xf9000300, size=0x20,int=9, mac=0:4:3:2:1:f, ethmod=tuntap, hostip=10.0.0.1
保存退出

然后运行 skyeye -e linux-2.4.x/linux
target sim
load
run

运行成功
# skyeye linux

Sash command shell (version 1.1.1)


执行ifconfig无反应
执行ifconfig eth0 up
反馈说找不到设备

我想就是中间我加了粗变红的那句话：缺省的I/O基址未定义 导致的问题。

有没高手能搞定的？

我的QQ 105538027 万分感谢！
