正文：
黑芝麻A1000 FAD 板上采用 NetworkManager 来管理网络，对应的服务NetworkManager.service.
没有采用network 方式，没有对应的network.service，network.service 是旧的管理方式，NetworkManager.service 是新的方式，很多linux 发行版有的还保留了network.service 方式，在我们板子上没有保留。 ------- 黑芝麻俊哥给的资料

通过串口连接主机和板子，使用串口才可以修改网络
先用两根数据线连接主机和板子的 USB2.0 FOR SOC A 和 USB2.0 DEBUG FOR SOA A + SOC B + TC397 口，经过试验，板子的A口好改网络

$ ls /dev/ttyUSB*
/dev/ttyUSB0  /dev/ttyUSB1  /dev/ttyUSB2  /dev/ttyUSB3

启动putty，putty 设置参考黑芝麻A1000 ubuntu18.04 PC用putty连接BST板子（四），A口选择 /dev/ttyUSB0
波特率 115200

$ sudo putty

同时启动 adb shell ，在这个里面修改脚本
ifconfig 查看网卡信息

nmcli配置静态ip地址
在adb shell 里面新建 com.sh 脚本文件，方便在putty 里面执行

sh-4.4# cd /home/root/
sh-4.4# vi com.sh

com.sh 内容：

#!/bin/bash
nmcli connection add type ethernet con-name eth0 ifname eth0 ipv4.addresses 192.168.1.102/24 ipv4.gateway 192.168.1.1
nmcli c load /etc/NetworkManager/system-connections/eth0.nmconnection
nmcli c m eth0 ipv4.method manual

通过串口在putty 里面执行

# cd /home/root
# chmod 775 com.sh
# ./com.sh

查看eth0 ip 状况

# nmcli -p device
