自制的initrd.img不能在skyeye.1.3.1加载？
您好，我按下步骤，用busybox-1.9.2自已做了个initrd.img文件，但是加载时却出错了，请问是什么原因呀？1.编译linux-2.6.30.5
#make s3c2410_defconfig
#make menuconfig
我设置了内核启动参数
1).Boot options ---> Default kernel command string:
mem=32M console=ttySAC0 root=/dev/ram initrd=0xc0800000,0x00800000 ramdisk_size=8192 rw
2).Device Drivers ---> Block devices??---> [ ] RAM disk support
相应的将默认的 (4096) Default RAM disk size (kbytes) 改成 8192;
3).将Device Drivers –> Character devices –> Serial drivers –> 8250/16550 and compatible serial support 去除
#make//能成功编译，但文件比较大。
2.编写skyeye.conf文件
# skyeye config file for S3C2440
arch:arm
cpu: arm920t
mach: s3c2440
# physical memory
mem_bank: map=M, type=RW, addr=0x30000000, size=0x00800000
mem_bank: map=M, type=RW, addr=0x30800000, size=0x00800000, file=./initrd.img
mem_bank: map=M, type=RW, addr=0x31000000, size=0x01000000
# all peripherals I/O mapping area
mem_bank: map=I, type=RW, addr=0x48000000, size=0x20000000
mem_bank: map=I, type=RW, addr=0x19000300, size=0x00000020
#net: type=cs8900a, base=0x19000300, size=0x20,int=9, mac=0:4:3:2:1:f, ethmod=tuntap, hostip=10.0.0.1
#lcd: type=s3c2410x, mod=gtk
uart:mod=stdio
#uart:mod=term
load_addr:base=0x30000000, mask=0xFFFFFF
#dbct:state=on
3.制做initrd.img
安装好了 busybox-处。9.2 后以命令制件步骤如下:
创建映像文件并挂到 initrd 目录
#mkdir initrd
#dd if=/dev/zero of=initrd.img bs=1k count=4096
#mke2fs -F -v initrd.img
#mount -o loop initrd.img initrd
将添加 busybox 到此映像文件
#cd initrd
#cp -r ../_install/* .
#创建必要的目录
#mkdir proc lib etc dev root home var tmp
#chmod 777 tmp
建立设备文件
#cd dev
#mknod -m 644 console c 5 1
#mknod -m 644 null c 1 3
#mknod -m 640 ram b 1 1
#mknod -m 644 mem c 1 1
#cd ..
创建脚本文件 etc/inittab,内容如下:
::sysinit:/etc/init.d/rcS
::askfirst:-/bin/sh
::restart:/sbin/init
::ctrlaltdel:/sbin/reboot
::shutdown:/bin/umount -a -r
::shutdown:/sbin/swapoff -a
设置此脚本执行权限
#chmod 644 etc/inittab
创建脚本文件 etc/init.d/rcS, 内容如下:
#!/bin/sh
/bin/mount -t proc none /proc
/sbin/ifconfig lo 127.0.0.1 up
/sbin/ifconfig eth0 10.0.0.2 netmask 255.0.0.0 up
hostname skyeye
mkdir /var/tmp
mkdir /var/log
mkdir /var/run
mkdir /var/lock
/bin/ash
设置此脚本执行权限
#chmod 755 etc/init.d/rcS
最后一步,执行实际的写入操作,生成 initrd.img
cd ..
umount initrd
4.出现的错误

Please press Enter to activate this console. (running) 感觉没有什么错误，应该都是正常的。你可以把skyeye.conf文件中的
"uart: mod=stdio" 改为
"uart: mod=term"
这样可以启动一个小窗口来显示串口信息，然后启动完毕，你敲入回车可以进入shell命令行
回复 2# ksh 的帖子
我们把uart:mod=stdio改成uart:mod=term后，也不行，小窗口出现如下错误信息：
Freeing init memor:92K
