快速使用Neardi RV1126指南

1. 设备框图

2. 电源接口

依据框图，把电源接口引出，如下图：

3. 调试串口

通常需要调试串口进行一些常用的命令设置，比如查看网络IP地址，查看kernel里相关的信息。首先，使用杜邦线如下方式引出串口：

上电启动后，有如下log:

4. 连接网线

依据框图， RJ45 pin定义如下：

引出网线，如下：

5. 连接摄像头

Neardi RV1126使用的是mipi接口摄像头，比如os04a10等。连接时注意顺序， 1<---> 1, 24 <--->24, 如下：

6. 使用rtsp客户端访问摄像头

上面都连接OK，系统起来后，可以在串口查看：

上面Log显示网络和摄像头都识别到了。

接下来使用RTSP client来访问摄像头，在Windows PC上面安装VLC, 之后打开VLC，如下：

上面192.168.1.233是RV1126设备的IP地址。这样，可以实时查看摄像头的视频流，如下：

7. 下载固件

使用Rockchip下载工具，把下载USB接口引出即可下载。
