第一章：HZHY AI300G 开箱

前言

首先感谢发烧友和和合众恒跃提供的这么好的机会，让我可以近距离接触并使用到高端的 RK3588 智能盒。这次，我想在这款设备上实现具有 Local AI 功能的工业用照明控制器。

开箱

今天上午收到了快递，就迫不及待的拍照留念。

再看一些和我手机 Magic 3 大小的对比图。AI300G 整体尺寸，长款和 Magic 3大小差不对，高度略微比身份证的宽度窄一点点。

基本测试

硬件的靓照看了之后，下面就到了基本功能测试环节，这里主要参考的文档是《HZHY-AI300G 测试手册》。因为我本次的项目主要使用的接口是网口和USB口。
这里我重点测试下网口速度以及 USB 功能。而软件方便，我本次的项目开发会涉及到应用层和驱动层的开发，这里我也简单分别写一个 hello world 的 APP 和 KO。

硬件测试

因为暂时没有何时的 HDMI 显示器，这里就从 DBG 口登陆测试，首先按照下图接好硬件，串口波特率选择 115200。

上电，就会看到类似下面的打印：

准备好了不？开始真正的测试环节：

1. wifi 测试，首次 ifconfig 无线网卡是不启用的，如下所示：

root@arm64-ubuntu:~# ifconfig

使用 rfkill unblock 0 ,然后 ifconfig wlxc8fe0ff45177 up 开启 wifi 后还是不行，
使用 iw 检测网卡（竟然崩溃了）：

root@arm64-ubuntu:~# iw wlxc8fe0ff45177 scan
scan aborted!

wifi 还是开起来了，询问了技术支持，建议使用图形化配置，我就尝试安装了 xrdp,并启用远程桌面连接测试：

发现 wifi 还是开不起来，呜呜呜，说是周一找研发看看，所以今天只能暂时搁置了。

2. 以太网测试,因为书房的路由器是百兆口的,所以就使用 iperf3 测试下百兆网口下的收发，数据如下：
   
3. USB 测试，接上 U 盘，查看下 dmesg,可以看到正常识别了 U 盘。

hzhy@arm64-ubuntu:~/Public/test_ko$ dmesg | tail

软件测试

1. APP 测试
   简单的 hello word 示例，直接在 AI300G 本地编译测试了：

hzhy@arm64-ubuntu:~/Public$ gcc hello_world.c
hzhy@arm64-ubuntu:~/Public$ ./a.out
Hello World!
hzhy@arm64-ubuntu:~/Public$ cat hello_world.c
#include < stdio.h >

int main()
{
     printf("Hello World!rn");

     return 0;
}

2. KO 测试
   这里暂时无法在线安装内核的头文件，这里就先搁置一下，后面有条件了就会补充。

总结

合众横跃的 AI300G 智能盒子，体积小巧，接口丰富，整个无风扇设计特别新颖！特别是技术支持的响应很及时，值得点赞。这真是一个嵌入式端的性能小怪兽！！！
目前残留的问题：

1. wifi 不能正常启用
2. 驱动因为缺少内核树无法本机编译
   争取下篇可以解决这两个问题，敬请期待。
