2440+2.6.33 初级内核+文件系统（三）

1.安装
 sudo apt-get install bison flex build-essential patch libncurses5-dev

2.理解
  交叉编译的库库文件lib路径：
        arm-2010.09/arm-none-linux-gnueabi/libc/armv4t/lib  一些.so文件
  我们需要的头文件
         arm-2010.09/arm-none-linux-gnueabi/libc/usr/include    一些 .h 文件
  注意：我们在建立文件系统时，需要拷贝交叉编译的lib文件到 自己的文件系统 /lib/
        arm-none-linux-gnueabi/libc/armv4t/usr/lib/*.so*  到 文件系统/lib下
        arm-none-linux-gnueabi/libc/armv4t/lib/    到lib下
    具体可以参考 移植手册

3.内核关于S3C2440的头文件
  arch/arm/mach-s3c2410/include
  arch/arm/mach-s3c2440
  arch/arm/plat-s3c24xx/include
  arch/arm/plat-samsung/include   不知道这个有没有用 ？？
  arch/arm/plat-s3c/ 

接下去的步骤与 TQ2440+2.6.30.4 步骤差不多
1.添加对ARM的支持
vim Makefile  第189行
        ARCH = arm
        CROSS_COMPILE=arm-linux-

2.修改输入平台时钟
  arch/arm/mach-s3c2440/mach-smdk2440.c
    第163 行，修改 16934400 为 12000000

3.修改机器码
   TQ板子使用的168 机器码
   arch/arm/tools/mach-types
   第379行  将362  为 168

补充：在 移植 自己的uboot 中，2010.06 时，吧 机器码修改为了  362
 
4.修改nand flash ，这步，与手册上一样
  arch/arm/plat-s3c24xx/common-smdk.c
 
  没有 修改 nand flash 的读写匹配时间 ，commmon-smdk.c的文件大概140 行的
  smdk_nand_info 结构体
 
5.支持 yaffs文件系统
  ./patch-ker.sh c /opt/me_linux/linux-2.6.33

6.busybox-1.18.4 下载了这个 
   在这个版本，make过程中没有错误，以前自己在2.6.30.4+busybox1.13 文件系统出现错误，
   可能是这个版本修改了bug了

7.建立文件系统 完全参考了 TQ移植手册10年版
  就是在/home/yu 建立了自己名字的文件
  相应的在passwd  修改为自己的名字 yu

   mkyaffs2image 工具使用：
    1.cp  mkxxxxximage_toos.tar.bz2  /home/ywx/yu/src/
    2.tar jxfv mkxxxxximage_tools.tar.bz2   生成了usr文件目录
    3.sudo cp usr/local/sbin/* /usr/local/sbin
   
 因为根目录/usr/local/sbin/ 已经添加到了 环境变量/etc/environmet下，所以我们可以直接使用
   
8.内核配置 make menuconfig 

   这部分可以参考  TQ2440+2.6.30.4 初级移植 （一）
  
    就是改了一个地方： 这次修改了没有错误出现了

general setup->
    [-yuweixian]local version.......

9.这样子就可以了 ，下载板子

Copy linux kernel from 0x00200000 to 0x30008000, size = 0x00200000 ... Copy Kernel to SDRAM done,NOW, Booting Linux......
Uncompressing Linux...

 
  分析：
    1.当时我仅仅制作了2.6.33 内核，下载到板子中，但是文件系统还是 TQ2440+2.6.30.4这个文件系统，出现了上面的错误。我想是文件系统匹配问题。
    2.所以，我继续做了文件系统arm-linux-gcc4.5.1，但是还是出现了上面的问题。一直没有解决
 
网上说的是：
   主要是串口问题：出现如下提示后停住 Uncompressing Linux done, booting the kernel
   

但是，还是没有解决，

   自己又下了一遍内核+文件系统 到板子中，就成功启动了，乖乖。


以后还是要一步一步小心的处理过程！！！！
