总结一下这一周来的经验

1）ubuntu 下编译uClinux需要自己装不少东西，否则很多最基本的指令都会出错

make menuconfig //要装ncurses

make xconfig //要装tck，tk两个包，会调用到里面的wish

make lib_only //针对2.4版本的uClinux，要装bison，否则也会不通过

所以，要像我一样最近上网不方便的话，备张Ubuntu8.04的DVD吧，里面不少软件的

2）配置内核有三个步骤，不要漏了

主界面--配置内核--配置用户程序这三个步骤

仿立宇泰的板子，直接下周他提供的三个cfg文件，推荐使用make menuconfig，直接载入就好了

如果不是的要自己配置，貌似我的板子带了一个kernel_44b0.cfg的配置文件，主要是kernel config的配置，s3c44b0x板子的内存地址，大小，flash地址，大小，时钟频率都要配对

3）编译后image文件架里面出现.bin文件，恭喜了，但不是丢如sdram就能用的哦，要考入flash才行

前几天我把bin直接丢sdram，能运行就见鬼啦（吐舌头）

最后留个启动界面，很高兴，尝试写个驱动看看
