好了，给大家看看保存后的boot.dat文件，

除了第一行，每行都是一个4字节长度的数。下面要做得是，分别把boot.dat中这些数和text.dat中的这些数放到boot[]和text[]的数组中，并将数组保存在头文件中。

首先删除头行

vim命令添加逗号:%s/$/,/g

添加数组名

搞定后的结果，如boot.h文件和text.h文件如下：

好了，到这就差不多了，表示机器码的二进制如今保存在我们的C语言头文件中了，下面就是要把头文件数组中的机器码烧写到Flash的对应的地址空间。

4 烧写Flash

本文操作环境下使用的Flash型号是AM29LV800BT。

为了烧写，首先你要做的是重新新建一个用于Flash烧写的工程。

烧写Flash的程序网上也有很多讲解，今天把烧写Flash调了出来，就当给大家福利，把我的Flash驱动程序给出来，
