求助：uclinux下网络无法配置？

yumiask

/> ifconfig y
ifconfig: ifconfig was not compiled with interface status display support.
pid 14: failed 256
/> ifconfig eh0 10.0.0.1
SIOCSIFADDR: No such device
pid 15: failed 256

conf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

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

ksh

把
/> ifconfig eh0 10.0.0.1
改为
/> ifconfig eth0 10.0.0.1

yumiask
