TQ2440+2.6.30.4 初级移植 （二）

说明：gcc 4.3.3  TQ制作的编译工具
     主机：ubuntu10.10
     开发板：TQ2440 256MB  2009年版 东华LCD-3.5寸
    
     uboot：u-boot_W35_20091031.bin
     内核文件： 由第一步制作的文件系统
     文件系统： 自己建立文件系统

          天嵌科技出品-Linux移植之Step By Step_V4.5_20100605.pdf  step10~11
   
说明：这里建立的文件系统参照的是2010年版的。
      这次实验使用的内核，的内核配置与初级移植（一），稍有不同，主要是对fs 重新配置了。
      添加了如下配置，为了解决 kernel panic

general setup->
     choose slab allocteror(slub(unquenued allocator))
这里是选择slab 分配器

配置单： 3-config.rar  
   
1.获取 busybox 源码 1.13.0.tar.bz2
        busybox 源码：
  注意：使用4.3.3 交叉编译环境，内核编译与文件系统编译需要移植编译器

2.配置 busybox 时，需要注意一点 [networking/libiproute/iptunnel.o] 错误 1

###########################
#####解决：make menuconfig 取消  network iptunnel

3.etc/inittab 这个问题？？ 请看：etc/inittab tq2440_serial0 问题解析

4.在制作 lib 目录时，
    当我从EABI-4.3.3拷贝库文件时，最后板子不能启动

Freeing init memory: 112K
Warning: unable to open an initial console.
Failed to execute /linuxrc.  Attempting defaults...
Kernel panic - not syncing: No init found.  Try passing init= option to kernel.
[<c002a700>] (unwind_backtrace+0x0/0xdc) from [<c025bb48>] (panic+0x40/0x110)
[<c025bb48>] (panic+0x40/0x110) from [<c00244c0>] (init_post+0xcc/0xf4)

   所以，我直接拷贝 tq制作好的 /lib 下 动态链接库，没有拷贝 *.ko fireware ts WebCam


5.成功处理移植

  但是 [\u@\h \W]#  为什么会这样？？
  我仅仅是修改etc/sysconfig/HOSTNAME 将HOSTNAME中的内容修改为ywx
  应该是 [root@EmbedSky /]  如是HOSTNAME的内容是EmbedSky
