我想自己做一个可以运行在SkyEye下的文件系统。
SkyEye: SkyEye-0.7.7
目标系统: xscale_lubbock
内核版本: Linux-2.6.7
文件系统: ramdisk, ext2, 16M
工具链: xscale-gcc-3.3.3（所在目录/usr/local/xscale/3.3.3）
busybox: busybox-1.00-rc3
KERNEL_DIR=/home/Kernel
BUSYBOX_DIR=/home/Busybox
RAMDISK_DIR=/home/Ramdisk
具体步骤如下：
1) 编译内核：
a) cd $KERNEL_DIR/linux-2.6.7
b) make ARCH=arm lubbock_defconfig
c) make ARCH=arm meunconfig
--->Choose: General Setup
--->(root=/dev/ram initrd=0xa1000000,0x00400000 console=ttyS0,115200 mem=64M)
--->Choose: Block Devices
---><*>RamDisk support
--->(16384) Default Ram disk size(kbytes)
---> Initial Ram disk (initrd) support
--->Save and Exit
d) make ARCH=arm CROSS_COMPILE=/usr/local/xscale/3.3.3/arm-linux-
在arch/arm/boot生成编译好的内核(zImage)
2) 编译busybox
a) cd $BUSYBOX_DIR/busybox-1.00-rc3
b) make menuconfig
--->Choose: Build Option
--->[ ] Build BusyBox as a static binary (no shared libs) (默认设置为选中这项，现在取消这项)
---> Do you want to build BusyBox with a Cross Compiler?
(/usr/local/xscale/3.3.3/bin/arm-linux-) Cross Compiler prefix
--->Choose: Networking Utilities
--->[ ] route (默认设置为选中这项，现在取消这项)
c) make
d) make install
所有的可执行文件默认被复制到busybox-1.00-rc3/_install目录中
3) 制作文件系统RamDisk
A) 生成基本的映像文件
a) cd $RAMDISK_DIR/
b) dd if=/dev/zero of=ramdisk.img bs=1024 count=16384
c) mke2fs ramdisk.img
d) file ramdisk.img (检查映像文件是否被格式化成为ext2的文件系统)
e) mkdir tmpDir
f) mount ramdisk.img tmpDir/ -o loop
g) cd tmpDir
h) mkdir bin
mkdir dev
mkdir etc
mkdir home
mkdir lib
mkdir mnt
mkdir proc
mkdir tmp
mkdir usr
mkdir var
i) cd dev
mknod console c 5 1
mknod fb0 c 29 0
mknod kmem c 1 2
mknod mem c 1 1
mknod null c 1 3
mknod ram b 1 0
mknod random c 1 8
mknod ts c 10 9
mknod tty c 5 0
mknod tty0 c 4 0
mknod tty1 c 4 1
mknod ttyAM0 c 204 16
mknod ttyAM0 c 204 17
mknod urandom c 1 9
mknod zero c 1 5
B) 配置系统启动脚本
a) cd ../etc
b) mkdir init.d
cd init.d
vi rcS
[Edit and input]
#!/bin/sh
mount -t proc proc /proc
mkdir /var/tmp
mkdir /var/log
mkdir /var/run
mkdir /var/lock
cat /etc/motd
[Save and Exit]
cd ..
c) vi inittab
[Edit and input]
(Nothing)
[Save and Exit]
d) vi inittab
[Edit and input]

ARMLinux for Skyeye

[Save and Exit]
e) vi fstab
[Edit and input]
proc /proc proc default 0 0
[Save and Exit]
C) 复制busybox的可执行文件和动态连接库
a) cd ..
b) cp $BUSYBOX_DIR/busybox-1.00-rc3/_install . -dpR
c) cd lib
cp /usr/local/xscale/3.3.3/lib/ld-2.3.2.so .
/usr/local/xscale/3.3.3/bin/arm-linux-strip ld-2.3.3.so
ln -s ld-2.3.2.so ld-linux.2.so
d) cd ../usr
mkdir arm-linux/lib -p
cd arm-linux/lib
cp /usr/local/xscale/3.3.3/lib/libc-2.3.2.so .
cp /usr/local/xscale/3.3.3/lib/libc.so .
/usr/local/xscale/3.3.3/bin/arm-linux-strip ld-2.3.3.so
ln -s libc-2.3.2.so libc.so.6
e) cd ../etc
f) vi ld.so.conf
[Edit and input]
/lib
/usr/local/arm-linux/lib
[Save and Exit]
cp /sbin/ldconfig .
export ROOT=$RAMDISK_DIR/tmpDir
ldconfig -r -C ld.so.cache
D) 生成基本的映像文件
a) cd ../../
b) umount ramdisk.img
c) rm tmpDir -rf
4) 制作文件系统RamDisk
cpu: xscale
mach: pxa_lubbock
mem_bank: map=I, type=RW, addr=0x40000000, size=0x0c000000
mem_bank: map=M, type=RW, addr=0xa0000000, size=0x00200000
mem_bank: map=M, type=RW, addr=0xa0200000, size=0x00100000, file=zImage, boot=yes
mem_bank: map=M, type=RW, addr=0xa0300000, size=0x00d00000
mem_bank: map=M, type=RW, addr=0xa1000000, size=0x01000000, file=./ramdisk.img
mem_bank: map=M, type=RW, addr=0xa2000000, size=0x02000000
mem_bank: map=M, type=RW, addr=0xc0000000, size=0x00096000
5) 运行SkyEye
a) 将上述步骤生成的zImage, ramdisk.img, skyeye.conf放在同一目录中
b) 运行skeye
[root@localhost xscale_lubbock]# skyeye
