原创 【米尔-瑞米派Remi Pi-兼容树莓派扩展模块--试用评测】永久IP地址固定

2024-4-17 17:04 1280 3 3 分类: MCU/ 嵌入式 文集: 嵌入式开发
一、根据开发手册网口一节参照如下:自动永久配置静态 IP 地址通过 ifconfig 命令和 ip 命令配置的 IP 地址断电之后就会丢失,如果需要使 IP 地址永久生效,就需要修改网络管理工具相应的配置文件。 使用 systemd-networkd 管理工具配置动态获取 IP 地址

结果IP在开发板重新启动后地址又变回默认的IP地址。后来查阅相关的资料才知道/usr/share/myir_test/age.sh里面文件需要屏蔽,于是用CP命令将整个文件夹重新命名。随后IP地址设置成功。

   总的来说开发如果需要开发自动的东西需要做的事情很多,最好自己刷一个新的系统以便后面开发工作进行。
