获取不到IP原因：配置文件缺失

配置文件参考busybox

/home/wy/hisi/SS524V100_SDK_V2.0.0.3/open_source/busybox/busybox-1.31.1/examples/udhcp

文件系统的目录以及文件

 /usr/share/udhcpc 目录下文件

/usr/share/udhcpc # ls default.bound default.deconfig default.script

 /etc/udhcpc 目录下文件

/etc/udhcpc # ls resolv.conf

 resolv.conf 文件内容

# cat resolv.conf  nameserver 192.168.0.1
