+> Windows环境下可以用通用的unzip工具解压，如7zip和winrar

-##### 2.1.1.2 配置开发环境目录
+> Linux/KylinOS环境下可以用unzip命令解压

-1. 创建Windows集成开发环境（DEV目录），如`D:/phytium-dev`, 将DEV目录添加在Windows环境变量中，变量名为`PHYTIUM_DEV_PATH`，如下图所示，保存环境变量，
+### 2.2 安装SDK开发环境

-> 对于Windows 10，在桌面左下角系统搜索框中输入“环境变量”即可进入环境变量编辑界面
+> 对于Windows 10平台，2.1章节的开发环境压缩包中通过msys2控制台提供了git工具

-> DEV目录中不要留空格
+> 对于Linux/KylinOS平台，可以通过`sudo apt-get install build-essential`安装git等工具

+# Newlib
+
+## 1. 例程介绍
+
+><font size="1">介绍例程的用途，使用场景，相关基本概念，描述用户可以使用例程完成哪些工作</font><br />
+
+Newlib是一个面向嵌入式系统的C运行库。最初是由Cygnus Solutions收集组装的一个源代码集合，取名为newlib，现在由Red Hat维护，本SDK中使用的是4.1.0版本，newlib可移植性强，具有可重入特性、功能完备等特点，已广泛应用于各种嵌入式系统中，相比于Glibc，newlib对嵌入式应用的支持更好
+
+## 2. 如何使用例程
+
+><font size="1">描述开发平台准备，使用例程配置，构建和下载镜像的过程</font><br />
+
+在Library Configuration中选择Use New Lib
+
+### 2.1 硬件配置方法
+
+><font size="1">哪些硬件平台是支持的，需要哪些外设，例程与开发板哪些IO口相关等（建议附录开发板照片，展示哪些IO口被引出）</font><br />
+
+- FT2000/4
+- D2000
+
+### 2.2 SDK配置方法
+
+><font size="1">依赖哪些驱动、库和第三方组件，如何完成配置（列出需要使能的关键配置项）</font><br />
+
+- 依赖本SDK提供的交叉编译链
+
+### 2.3 构建和下载
+
+><font size="1">描述构建、烧录下载镜像的过程，列出相关的命令</font><br />
+
+- host侧设置重启host侧tftp服务器
+```
+sudo service tftpd-hpa restart
+```
+
+- 开发板侧使用bootelf命令跳转
+```
+setenv ipaddr 192.168.4.20  
+setenv serverip 192.168.4.50 
+setenv gatewayip 192.168.4.1 
+tftpboot 0x90100000 baremetal.elf
+bootelf -p 0x90100000
+```
+
+### 2.4 输出与实验现象
+
+><font size="1">描述输入输出情况，列出存在哪些输出，对应的输出是什么（建议附录相关现象图片）</font><br />
+
+- 通过u-boot启动，完成浮点打印
+```
+# bootelf -p 0x90100000
+## Starting application at 0x80100000 ...
+hello baremetal phytium 3.141500
+
+```
+
+## 3. 如何解决问题
+
+><font size="1">主要记录使用例程中可能会遇到的问题，给出相应的解决方案</font><br />
+
+## 4. 修改历史记录
+
+><font size="1">记录例程的重大修改记录，标明修改发生的版本号 </font><br />
+
