用skyeye0.8.0仿真出现的问题

qq425887742

skyeye运行linux2.4.18的问题

skyeye.conf配置如下：
#skyeye config file sample
cpu: arm720t
mach: ep7312
mem_bank: map=I, type=RW, addr=0x80000000, size=0x00010000
mem_bank: map=M, type=RW, addr=0xc0000000, size=0x00200000
mem_bank: map=M, type=RW, addr=0xc0200000, size=0x00200000, file=./initrd
mem_bank: map=M, type=RW, addr=0xc0400000, size=0x01000000
log: logon=0,logfile=/tmp/test.log,start=5000000,end=6000000
在skyeye上运行时显示如下：
[root@www arm_skyeye]# skyeye

说明：
initrd为文件系统名
skyeye0.8.0版
initrd文件系统采用BUSYBOX1.0.0制作
配置内核
System type-->CLPS711X/EP721X-BASED-->CLEP7312
制作文件系统时修改了
#define INIT_SCRIPT  "/etc/inittab"
而且把网络支持限了
