前言：

   声明一下：如果想按照本方法移植的话，需参照国嵌的手册：4-2-6，上面讲解的步骤和解析。
   本人买了一块mini2440，同时买了一套国嵌的实验手册，可是做到4-2-6节的时候出了问题，因为照着实验手册做的话，下到nor flash会提示这个信息，如下
上面提示到nor flash芯片不是sst39vf1601，而是那个am29lv160b，呵呵，同时下面的扇区信息也不对，怎么是35个呢？2M存储量，一个是64K，怎么是35个，不是应该是国嵌上的那个32么？
同时还有一个疑问：这个移植的最终目的就是实现对nor flash的擦写，可是当你按照手册上的方法命名一个环境变量，保存，重启一下，在显示的时候发现没了。。。。
从以上信息可以得出一个结论：你的移植失败了。。。。
一.
为什么呢？因为国嵌的开发板本来是那个sst39vf1601，可是有很多人买并不是这个（你细心点看看你板子上的nor flash是不是），如果是的话，那移植不会出问题，如果不是（我的就不是），我的上面标的是：S29AL016.....,我查了一下，是spansion公司的（谁知道是啥公司，网上都找不到），这款芯片的id是：122c4（还有一个名字差不多，id是122c9，关于id，这个很重要，我的方法是用jlink来查看的），并且很奇怪，这款芯片和上面图片中的出现的那个AM29LV160T是一个id，也不知道为什么2个公司生产出来的芯片会是一个id，就是因为这是一个id，所以我们可以用AM29LV160T来配置。
解释了这么多，意思也该明白了，uboot识别出了你的芯片，可是你按手册上移植的时候并不是按照这个芯片移植的，所以出错了，解决办法（我不知道我的这个方法内部会不会有一些毛病，但是最终显示的界面证明我自己移植成功了）：我是改造了2.6上的移植方法，换成了AM29LV160T:
可以自己查看两个芯片的时序图 
看到了吧，这两款芯片的操作时序并不一样，所以你要好好改了，具体内容我就不扯了，下面我贴出我移植的关键的2个文件中的代码，你只要把这2个文件的代码复制到你的相应文件中，编译一下就成了：
你可以把这2个文件的内容和国嵌4.2.6中移植中的对比一下，有些地方我同样修改了，但是因为这个文件中支持这个nor flash，所以说，有好些步骤，不需要动：
1.board/mini2440/flash.c （可以直接复制到你的同样目录下的flash.c中（PS把原先的flash.c内容清空，复制一下代码就行了）
