# 开发环境搭建示图

 1\) 请将SE3、笔记本电脑组一个局域网

2\) 配置SE3 IP static address

```
** 更改 interfaces 文件，address即可 **
# sudo vim /etc/network/interfaces.d/eth0
auto eth0
iface eth0 inet static
        address 192.168.1.185
        netmask 255.255.255.0
        gateway 192.168.1.1
        dns-nameservers 192.168.1.1
# 退出保存文件
sudo ip addr flush eth0
sudo systemctl restart networking.service
# reboot系统后，ip地址变成192.168.1.185
# ifconfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.1.185  netmask 255.255.255.0  broadcast 192.168.1.255
        inet6 fe80::9c25:81ff:fe76:adf0  prefixlen 64  scopeid 0x20<link>

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://1684.gitbook.io/sophon-se3-quickstart-for-beginners/se3-kai-fa-huan-jing-da-jian/kai-fa-huan-jing-da-jian-shi-tu.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
