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：

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

               恳请帮助，为何会出现不正常启动现象？

use the latest SkyEye version and linux-2.6 version。 We do not give support for old skyeye version any more. Linux-2.4 maybe need some arm patch to support ep7312

You can try some 2.6.x kernel versions .As fas as I know ,some related patches from www.arm.linux.uk.org is needed for linux-2.4.18.

qq425887742 发表于 2008-4-16 19:15:59

我用的是linux2.6.0+patch-2.6.0-rmk1安装了补丁，能给一下具体的从编译到运行的步骤吗？
