【R329开发板评测】Windows下R329开发板+Debian系统的使用体验

前言

非常有幸获得由极术社区和矽速科技提供的R329开发板，下面就本人在Windows下使用R329开发板的体验进行总结。

使用工具

本人使用的烧录工具：Win32 Disk Imager；串口驱动：CH341SER；终端软件：MobaXterm

烧录debian镜像

debian镜像地址和烧录教程可参考链接
烧录完成后将下面OTC口接上电，会显示两个小企鹅

将板子连上wifi并用SSH连接

在登陆界面中分别输入

maixsense login:root
Password:sipeed

登录后界面如下

输入ip addr show，查看开发板ip地址

打开终端软件MobaXterm
新建SSH连接，并输入刚刚查看的ip地址和账号

连接完成后终端显示如下

在终端下体验周易

由于默认镜像的 ~/zhouyi_test 目录下放置了zhouyi_cam 例程和模型，我们可以直接输入以下指令进行体验

cd ~/zhouyi_test/build
make clean
cmake ..
time make -j2

对应的终端log如下

root@maixsense:~# cd ~/zhouyi_test/build
root@maixsense:~/zhouyi_test/build# make clean
root@maixsense:~/zhouyi_test/build# cmake ..
-- Configuring done

体验实时识别模型

cd ~/zhouyi_test
bash run.sh

存在问题和解决办法

当wifi突然断开或者通信延迟过大时会有概率使开发版卡住，试试检测会瞬间掉帧到4.7fps，并且输出log也会卡住。

建议使用手机热点连接，或者电脑的移动热点连接，能增加稳定性（还可以省去查终端IP步骤）。
