本目录是大赛提供的功能测试程序的目录，包括编译所需的源代码和目标文件。
2+
3+
本目录需要在Linux环境下,运行终端，进入本目录，执行Makefile脚本进行编译。
4+
5+
6+
1. 目录的结构如下：
7+
8+
+--./ : 功能测试编译目录
9+
|
10+
|--inst/ : 82个功能点源码，最终测试中实际只测试n82一个功能点
11+
|
12+
|--include/ : 编译所需的头文件目录
13+
|
14+
|--obj/ : 编译生成的目标文件目录
15+
|
16+
|--bin.lds.S : 链接脚本生成文件
17+
|
18+
|--convert.c : RAM初始化文件的转换代码
19+
|
20+
|--start.S : 测试程序的启动代码
21+
|
22+
|--Makefile : 编译脚本
23+
|
24+
|--rules.make : 编译规则，供Makefile调用
25+
|
26+
|--Readme_first.txt : 本文档
27+
28+
29+
2. 编译方法
30+
31+
(1) 编译前，请保证已经配置好交叉编译环境。
32+
33+
(2) 在当前目录下打开终端，执行make，即可在obj目录下生成测试所需的所有文件。
34+
35+
(3) 想清除所有编译文件请执行make clean。
