第一章：HZHY AI300G 開(kāi)箱

前言

首先感謝發(fā)燒友和和合眾恒躍提供的這么好的機(jī)會(huì)，讓我可以近距離接觸并使用到高端的 RK3588 智能盒。這次，我想在這款設(shè)備上實(shí)現(xiàn)具有 Local AI 功能的工業(yè)用照明控制器。

開(kāi)箱

今天上午收到了快遞，就迫不及待的拍照留念。

再看一些和我手機(jī) Magic 3 大小的對(duì)比圖。AI300G 整體尺寸，長(zhǎng)款和 Magic 3大小差不對(duì)，高度略微比身份證的寬度窄一點(diǎn)點(diǎn)。

基本測(cè)試

硬件的靚照看了之后，下面就到了基本功能測(cè)試環(huán)節(jié)，這里主要參考的文檔是《HZHY-AI300G 測(cè)試手冊(cè)》。因?yàn)槲冶敬蔚捻?xiàng)目主要使用的接口是網(wǎng)口和USB口。
這里我重點(diǎn)測(cè)試下網(wǎng)口速度以及 USB 功能。而軟件方便，我本次的項(xiàng)目開(kāi)發(fā)會(huì)涉及到應(yīng)用層和驅(qū)動(dòng)層的開(kāi)發(fā)，這里我也簡(jiǎn)單分別寫(xiě)一個(gè) hello world 的 APP 和 KO。

硬件測(cè)試

因?yàn)闀簳r(shí)沒(méi)有何時(shí)的 HDMI 顯示器，這里就從 DBG 口登陸測(cè)試，首先按照下圖接好硬件，串口波特率選擇 115200。

上電，就會

準(zhǔn)備好了不？開(kāi)始真正的測(cè)試環(huán)節(jié)：

wifi 測(cè)試，首次 ifconfig 無(wú)線網(wǎng)卡是不啟用的，如下所示：

使用 rfkill unblock 0 ,然后 ifconfig wlxc8fe0ff45177 up 開(kāi)啟 wifi 后還是不行，
使用 iw 檢測(cè)網(wǎng)卡（竟然崩潰了）：

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

wifi 還是開(kāi)起來(lái)了，詢問(wèn)了技術(shù)支持，建議使用圖形化配置，我就嘗試安裝了 xrdp,并啟用遠(yuǎn)程桌面連接測(cè)試：

發(fā)現(xiàn) wifi 還是開(kāi)不起來(lái)，嗚嗚嗚，說(shuō)是周一找研發(fā)看看，所以今天只能暫時(shí)擱置了。

以太網(wǎng)測(cè)試,因?yàn)闀?shū)房的路由器是百兆口的,所以就使用 iperf3 測(cè)試下百兆網(wǎng)口下的收發(fā)，數(shù)據(jù)如下：
USB 測(cè)試，接上 U 盤(pán)，查看下 dmesg,可以看到正常識(shí)別了 U 盤(pán)。

軟件測(cè)試

APP 測(cè)試
簡(jiǎn)單的 hello word 示例，直接在 AI300G 本地編譯測(cè)試了：

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;
}

KO 測(cè)試
這里暫時(shí)無(wú)法在線安裝內(nèi)核的頭文件，這里就先擱置一下，后面有條件了就會(huì)補(bǔ)充。

總結(jié)

合眾橫躍的 AI300G 智能盒子，體積小巧，接口豐富，整個(gè)無(wú)風(fēng)扇設(shè)計(jì)特別新穎！特別是技術(shù)支持的響應(yīng)很及時(shí)，值得點(diǎn)贊。這真是一個(gè)嵌入式端的性能小怪獸?。?！
目前殘留的問(wèn)題：

wifi 不能正常啟用
驅(qū)動(dòng)因?yàn)槿鄙賰?nèi)核樹(shù)無(wú)法本機(jī)編譯
爭(zhēng)取下篇可以解決這兩個(gè)問(wèn)題，敬請(qǐng)期待。
