配置静态地址Ipv4

查看平台

uname -a 
cat /etc/os-release

查看网络是哪个管理的

 systemctl list-units --type=service | grep

查看网络具体由什么文件配置的

 networkctl status end0

编辑配置文件并重启

 vi /usr/lib/systemd/network/80-wired.network

[Match]
Name=end0

[Network]
Address=172.30.0.10/24
Gateway=172.30.0.1
DNS=8.8.8.8

sudo systemctl restart systemd-networkd

编写代码并编译

#include <stdio.h>

int main() {
    printf("Hello, World!\n");
    return 0;
}

编译

$CC main.c

检查文件属性

file a.out 
a.out: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-armhf.so.3, BuildID[sha1]=*******f, for GNU/Linux 5.15.0, with debug_info, not stripped

ssh连接并传输文件

总结

我使用ubuntu22.04 环境配置sdk,并编译程序，利用ssh方式传输文件到开发板上，其中将开发板的地址改为静态地址方便下次连接使用，网口使用的是usb 网卡 在windows环境下直接配置固定地址即可
