【GM3568JHF】FPGA+ARM异构开发板使用指南：WIFI

news 2025/9/6 4:08:20

开发板使用RTL8723DU模块，默认已适配好WIFI部分

连接WIFI

如图所示，找到系统右上角点击网络图标连接WIFI

使用ifconfig命令查看ip地址等信息

root@linaro-alip:/# ifconfig
···

连通性测试

执行如下命令查看获取的 IP 地址，并通过 ping 命令测试开发板与 PC 机通信是否正常。 192.168.49.85为PC实际的IP地址，请确保开发板与 PC 机在同一局域网内。

root@linaro-alip:/# ping 192.168.49.85 -I wlx78228877b4a5 -c 8
ping 192.168.49.85 -I wlx78228877b4a5 -c 8

TCP带宽测试

如下使用iperf3工具测试开发板与 PC 机的网络通信带宽。

服务端

在开发板上联网安装iperf3工具，执行如下命令：

root@linaro-alip:/# sudo apt update
root@linaro-alip:/# sudo apt install iperf3

开发板做服务端，执行以下命令:

root@linaro-alip:/# iperf3 -s
-----------------------------------------------------------
Server listening on 5201 (test #1)
-----------------------------------------------------------

客户端

windows的iperf3工具可以在测试工具包中获取。

在windows系统中打开powershell，进入iperf3工具所在路径下 windows做客户端发送数据，执行以下命令：

.\iperf3.exe -c 192.168.137.149 // 192.168.137.149为服务端IP地址

测试结果

服务端

root@linaro-alip:/# iperf3 -s
