作者：mutes  
硬件环境：ST2410X开发板（CPU：S3C2410X）  
内核版本：linux2.6.36  
运行环境：Window7  Vmware workstation7.1   FC13  
交叉编译环境：Arm-linux-gcc-4.3.2 with EABI  
移植时间：2011.09.15  
  
1． 准备必要的文件  
首先去官方网站下载最新的 linux 内核  
ftp://ftp.kernel.org/pub/linux/kernel/v2.6/linux-2.6.36.tar.bz2  
因为 linux-2.6.36内核需要更新版本的编译器，所以需要下载交叉编译器  
2． 安装文件  
把 arm-linux-gcc 安装在 /opt 目录下，安装方法和安装 gcc2.95.3 和 gcc3.3.2 是相同的！  
接下来需要解压 linux 内核，输入命令：  
 tar jxvf linux-2.6.36.tar. bz2  
内核被解压到 linux-2.6.36 目录下。  
3． 修改 makefile 文件  
内核的编译是根据 makefile 文件的指示进行的， Makefile 文件来组织内核的各模块之间的关系，记录了各个模块之间的相互联系和依赖关系。  
我们首先修改 linux-2.6.36 的根目录下的 makfile 文件，须改的主要内容是目标代码的类型和为编译内核指定一个编译器。将以下内容  
\#ARCH   ?= $(SUBARCH)  
\#CROSS\_COMPILE     ?=  
更改为如下内容：  
ARCH   ?= arm  
CROSS\_COMPILE ?=/opt/usr/local/arm/4.3.2/bin/arm-linux-  
  
４make s3c2410\_defconfig;make uImage；

uboot一般使用mkimage工具先制作一个启动映象文件来引导识别内核的，uboot源代码的tools/目录下有mkimage工具，这个工具可以用来制作不压缩或者压缩的多种可启动映象文件。mkimage在制作映象文件的时候，要先编译uboot，然后将u-boot-1.1.6/tools/mkimage拷贝到/usr/sbin目录下

最后  
 cp arch/arm/boot/uImage /tftpboot/  
ok可以启动试一下了。  
  
5 修改 arch/arm/plat-s3c24xx/common-smdk.c 文件  
说明：这里linux-2.6.36的设置分区与其他版本如2.6.14或2.6.11有点区别，其他版本是修改arch/arm/machs3c2410/devs.c和arch/arm/machs3c2410/mach-smdk2410.c 但linux-2.6.36设置这些文件无效。  
设置Nand Flash的分区和信息，下面是我的分区结构（与BIOS的分区保持一至）：  
name: 代表分区名字  
size: 代表flash分区大小(单位：字节)  
offset: 代表flash分区的起始地址(相对于0x0的偏移)  
目标板计划分4个区，分别存放loader, param,kernel, root以及以便以后扩展使用的用户文件系统空间。  
注：分区表信息要参考你自己的内核和文件系统的大小，排布来设置，BIOS中的分区信息要和mtd分区信息一致，分多少个区由你自己决定，我的就只分了4个区^\_^。  
static struct mtd\_partition smdk\_default\_nand\_part\[\] = \{  
        \[0\] = \{  
                .name   = "loader",  
                .size   = SZ\_256K,  
                .offset = 0,  
        \},  
        \[1\] = \{  
                .name   = "kernel",  
                .offset = MTDPART\_OFS\_APPEND,  
                .size   = SZ\_1M + SZ\_256K + SZ\_512K,  
        \},  
        \[2\] = \{  
                .name   = "root",  
                .offset = SZ\_2M,  
                .size   = SZ\_32M,  
        \},  
        \[3\] = \{  
                .name   = "user1",  
                .offset = MTDPART\_OFS\_APPEND,  
                .size   = MTDPART\_SIZ\_FULL,  
        \}  
\};  
修改nand flash的参数：  
在同一个文件中找到  
static struct s3c2410\_platform\_nand smdk\_nand\_info = \{  
    .tacls        = 20,  
    .twrph0        = 60,  
    .twrph1        = 20,  
    .nr\_sets    = ARRAY\_SIZE(smdk\_nand\_sets),  
    .sets        = smdk\_nand\_sets,  
\};  
改成  
static struct s3c2410\_platform\_nand smdk\_nand\_info = \{  
    .tacls        = 0,  
    .twrph0        = 30,  
    .twrph1        = 0,  
    .nr\_sets    = ARRAY\_SIZE(smdk\_nand\_sets),  
    .sets        = smdk\_nand\_sets,  
\};  
  
drivers/mtd/nand/s3c2410.c  
839                 chip->ecc.mode      = NAND\_ECC\_NONE;//NAND\_ECC\_SOFT;  
  
开发环境必须的网卡驱动。开发板用的是cs8900的网卡。  
  
6.将准备好的cs8900.c/cs8900.h两个文件复制到drivers/net/arm目录下  
  
7.在include/net/目录下创建文件smdk2410.h，并添加如下代码：  
　　\#define pSMDK2410\_ETH\_IO        \_\_phys\_to\_pfn(0x19000000)  
　　\#define vSMDK2410\_ETH\_IO        0xE0000000  
　　\#define SMDK2410\_EHT\_IRQ        IRQ\_EINT9  
  
8.在arch/arm/mach-s3c2410/mach-smdk2410.c中加入"\#include <net/smdk2410.h>"  
在struct map\_desc smdk2410\_iodesc\[\]中添加cs8900相应的io空间映射：  
　　　\{vSMDK2410\_ETH\_IO, pSMDK2410\_ETH\_IO, SZ\_1M, MT\_DEVICE\}  
  
  
9.在drivers/net/arm/目录下的Makefile中加入cs8900相关项：  
　　　　obj-$(CONFIG\_ARM\_CS8900)    += cs8900.o  
　在drivers/net/arm/目录下的Kconfig中加入cs8900相关项：  
config ARM\_CS8900  
    tristate "CS8900 support"  
    depends on NET\_ETHERNET && ARM && (ARCH\_SMDK2410 || ARCH\_ZL2440 || MACH\_MINI2440)  
    help  
      Support for CS8900A chipset based Ethernet cards. If you have a  
      network (Ethernet) card of this type, say Y and read the  
      Ethernet-HOWTO, available from  
      <http://www.tldp.org/docs.html\#howto> as well as <file:Documentation/networking/cs89x0.txt>.  
     
      To compile this driver as a module, choose M here and read  
      <file:Documentation/networking/net-modules.txt>.  The module will be called     
  
10.make menuconfig选中cs8900选项，去掉dm9000选项。  
  
11.make 之后加载到开发板，提示

无法挂载NFS文件系统，在肉核启动信息中可以找到下面信息  
Kernel command line: root=/dev/hda1 ro init=/bin/bash console=ttySAC0  
原来uboot没有将设置好的命令行参数传递到内核，因为在uboot中我已经设置了  
bootargs=root=/dev/nfs rw nfsroot=192.168.1.54:/opt/nfs/filesys ip=192.168.1.56:192.168.1.54:192.168.1.1:255.255.255.0 console=ttySAC0,115200  
修改内核源码中的.config文件，设置好CONFIG\_CMDLINE为  
CONFIG\_CMDLINE="root=/dev/nfs rw nfsroot=192.168.1.54:/opt/nfs/filesys ip=192.168.1.56:192.168.1.54:192.168.1.1:255.255.255.0 init=/linuxrc console=ttySAC0,115200"  
  
可以启动了。  
  
下面说一下内核中网卡和cs8900驱动相关的话题：  
由于内核更新后，struct net\_device结构体及相关宏定义有变化，或造成在2.6.16/2.6.22/2.6.24内核工作的cs8900驱动在2.6.36上不能编译通过。主要修改如下：  
    1>"IRQT\_RISING"改成"IRQ\_TYPE\_EDGE\_RISING"  
    2>2.6.36内核的net\_device中没有“priv“和"mc\_list"项”。代码都要作相应修改。  
    3>以前内核(2.6.16/2.6.22/2.6.24)struct net\_device中的函数指针域在2.6.36中都放在struct net\_device\_ops类型的指针netdev\_ops指向的结构体中。也要作相应修改。

**根文件系统的创建**

建立 Linux 目录树,创建根文件系统的基本目录结构  
  
我把这个过程做成了shell脚本文件mkrootfs，很方便！  
mkrootfs文件如下：  
  
\#! /bin/sh  
    echo "creatint rootfs dir......"  
    mkdir rootfs  
    cd rootfs  
    echo "making dir : bin dev etc lib proc sbin sys usr"  
    mkdir bin dev etc lib proc sbin sys usr  
    mkdir usr/bin usr/lib usr/sbin lib/modules  
\# Don't use mknod ,unless you run this Script as root !  
    mknod -m 600 dev/console c 5 1  
 mknod -m 666 dev/null c 1 3  
    echo "making dir : mnt tmp var"  
    mkdir mnt tmp var  
    chmod 1777 tmp  
    mkdir mnt/udisk mnt/sd mnt/pcshare mnt/data  
    echo "making dir : home root "  
    mkdir home root  
    cp -ar fs\_public/\* rootfs/  
echo "done ok!"  
  
注意创建完成后将其修改为可执行权限，在创建dev/console dev/null时须还要root权限  
\[root@localhost myroot\]\# ./mkrootfs  //在 myroot 中建立 Linux 目录树  
配置和编译 busybox  
  
1、准备工作  
首先从 http://www.busybox.net/downloads/busybox-1.19.2.tar.bz2/下载 源码包，  
解压  
tar jxvf busybox-1.19.2.tar.bz2  
进入解压后的目录  
cd busybox-1.19.2  
2. 修改目录下Makefile文件  
注释(第151-154行)  
\#SUBARCH := $(shell uname -m | sed -e s/i.86/i386/ -e s/sun4u/sparc64/ \\  
\#                 -e s/arm.\*/arm/ -e s/sa110/arm/ \\  
\#                 -e s/s390x/s390/ -e s/parisc64/parisc/ \\  
\#                 -e s/ppc.\*/powerpc/ -e s/mips.\*/mips/ )  
将175-176行的  
ARCH        ?= $(SUBARCH)  
CROSS\_COMPILE    ?=  
修改为：  
ARCH        ?= arm  
CROSS\_COMPILE    ?= /opt/usr/local/arm/4.3.2/bin/arm-linux-  
 164 \#CROSS\_COMPILE ?=  
 165 CROSS\_COMPILE ?= /opt/usr/local/arm/4.3.2/bin/arm-linux-  
  
3、配置busybox  
\[root@localhost busybox-1.19.2\]\# make menuconfig  
在原有的基础上修改如下：  
Busybox Settings --->  
      General Configuration  --->   //使用默认  
      Build Options  --->  
          \[ \] Build BusyBox as a static binary (no shared libs)

           (/opt/myroot/rootfs) BusyBox installation prefix  /\* 指定busybox编译后按装路径 \*/  
        Busybox Library Tuning  --->  
           \[\*\] Support for /etc/networks  
           \[\*\]   Additional editing keys      
           \[\*\] Command line editing  在shell中命令的自动补全和命令可编辑还是挺方便的。这些功

           \[\*\]   vi-style line editing command  
           (15)  History size   
           \[\*\]   History saving   
           \[\*\]   Tab completion  
           \[\*\]     Username completion   
           \[\*\]   Fancy shell prompts  
           \[ \] Use clock\_gettime(CLOCK\_MONOTONIC) syscall//选上时编译产生libbb/time.c:20:  
  
error: \`CLOCK\_MONOTONIC' undeclared 错误  
           \[ \] Use ioctl names rather than hex values in error messages  
        
Debian Utilities  ---> 选项全部N掉  
Init Utilities  --->  
  \[\*\] init                                                              
  \[ \]   debugging aid

  \[\*\]   Support running init from within an initrd (not initramfs)        
  \[\*\] poweroff, halt, and reboot                                        
  \[\*\] mesg  
Login/Password Management Utilities  --->选项全部N掉，后面单独使用TinyLogin。（因为集成的好像不是很好用）  
Linux Ext2 FS Progs  --->选项全部N掉  
Linux Module Utilities  --->  
      \[N\] Support version 2.2.x to 2.4.x Linux kernels //在此我的内核是2.6的，所以没去除  
Linux System Utilities  --->  
  \[\*\] fdisk                                                             
  \[\*\]   support over 4GB disks                                          
  \[\*\]   Write support  
  \[\*\] mdev                                    //支持mdev                          
  \[\*\]   Support /etc/mdev.conf                                            
  \[\*\]     Support command execution at device addition/removal            
  \[\*\]   Support loading of firmwares

  \[\*\]   Support loopback mounts       //提供支持－o loop文件挂载                              
  
      
  \[ \]   Support for the old /etc/mtab file //选上后將在/etc/下自动创建mtab文件 用以记录mount  
  
挂载信息  
   
Miscellaneous Utilities  --->  
  \[ \] devfsd (obsolete)

Shells  --->  
 Choose your default shell (ash)  --->  
   /\* (X) ash 选中 ash，这样生成的时候才会生成 bin/sh 文件  
   \* 看看我们前头的 linuxrc 脚本的头一句：  
   \* \#!/bin/sh 是由 bin/sh 来解释执行的\*/  
      --- ash 选择ash  
      ---   Ash Shell Options 下的选项全选或采用默认  
ipsvd utilities  --->  选项全部N掉     
其它为相关命令根据须要选择，在此我将所有的都选上了。  
其它采用默认，保存退出，产生.config文件  
4、编译 busybox  
\[root@localhost busybox-1.19.2\]\# make  
  AR      libbb/lib.a  
  LINK    busybox\_unstripped  
Trying libraries: crypt m  
 Library crypt is needed  
 Library m is needed  
Final link with: crypt m  
                                  
5.将编译好的命令安装到指定的目录上。  
\[root@localhost busybox-1.19.2\]\# make install  将生成 bin,sbin两个文件夹和一个linuxrc文件.  
我是动态编译所以查看一下需要的动态库  
\[root@localhost busybox-1.19.2\]\# arm-linux-readelf -d busybox  
  
  
修改和创建必要的文件  
inittab 文件如下：  
\# This is run first except when booting  
::sysinit:/etc/init.d/rcS  
  
\# Start an "askfirst" shell on the console  
::askfirst:-/bin/sh  
  
\# Stuff to do when restarting the init process  
::restart:/sbin/init  
  
\#::once:/usr/sbin/inetd  
\#::once:/usr/etc/rc.local  
  
\# Stuff to do before rebooting  
::ctrlaltdel:/sbin/reboot  
::shutdown:/bin/umount -a –r  
这里有个错误：  
/bin/sh: can't access tty; job control turned off  
修改inittab文件中  
::askfirst:/bin/sh  
为  
::askfirst:-/bin/sh  
  
fstab文件如下：  
\#device         mount-point     type    options       dump fsck order  
proc            /proc           proc    defaults        0 0  
tmpfs           /tmp            tmpfs   defaults        0 0

var             /var            tmpfs   defaults        0 0  
tmpfs           /dev            tmpfs   defaults        0 0  
var             /dev            tmpfs   defaults        0 0  
ramfs           /dev            ramfs   defaults        0 0  
  
增加为SHELL导入全局变量的文件profile  
profile文件如下：  
  
\# Ash profile  
\# vim: syntax=sh  
  
\# No core files by default  
\#ulimit -S -c 0 > /dev/null 2>&1  
  
USER="\`id -un\`"  
LOGNAME=$USER  
PS1='\[\\u@\\h \\W\]\\$ '  
\#PS1='\[$USER@$HOSTNAME$PWD\]\\$ '  
PATH=$PATH  
  
HOSTNAME=\`/bin/hostname\`  
  
export USER LOGNAME PS1 PATH  
  
init.d/rcS内容如下：  
\#! /bin/sh  
  
\#echo "^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^"

\#echo "^                                         ^"  
\#echo "^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^"  
  
PATH=/sbin:/bin:/usr/sbin:/usr/bin  
runlevel=S  
prevlevel=N  
umask 022  
export PATH runlevel prevlevel  
  
\#  
\#       Trap CTRL-C &c only in this shell so we can interrupt subprocesses.  
\#  
trap ":" INT QUIT TSTP  
  
  
/bin/mount -a  
  
/bin/mkdir -p /var/lib

制作文件系统时，超级终端出现\[\\u@\\h \\W\]\#  
解决方法：  
法一：在busybox编译里  
make menuconfig  
busybox settings->busybox library tuning->username completion、fancy shell prompts选上。  
就可以了  
法二：处理方法是：/etc/profile:PS1='\[$USER@$HOSTNAME $PWD\]\#

错误原因：   
用arm-linux-gcc 4.00以上的编译器做出都 文件系统老是报这个错 ，  
而用rm-linux-gcc 3.xx 版本都都不会，看来一下内核的配置  
原来问题在这里  
  
Kernel Features  --->  
            \[\*\] Use the ARM EABI to compile the kernel                   
            \[\*\]   Allow old ABI binaries to run with this kernel (EXPERIMENTA)  
把这个选上就可以了
