arch/arm/boot/dts/sun8i-v3s-licheepi-zero.dts

[url=https://whycan.cn/files/members/1206/sun8i-v3s-licheepi-zero 设备树.rar] sun8i-v3s-licheepi-zero 设备树 [/url]

重新编译生产设备树 dtb 文件
[code]
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- dtbs
[/code]

udhcpc 配置 ip 失败解决办法，从buildroot 编译好的 rootfs 复制 /usr/share 目录下所有配置文件到对应目录下。

修改 etc/network/interfaces
[code]
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp

[/code]

[code]
localhost:~# ifconfig
