最近入手了一块友善的NanoPi NEO
全志的H3芯片，512M内存，板载100M网口和USB2.0口，接口齐全。
虽然有官方提供的源码可以折腾，但还是选择从头开始。

- 文件系统
解压Ubuntu core到TF卡ROOT分区
sudo cp -a /usr/bin/qemu-arm-static rootfs/usr/bin/
sudo chroot rootfs/
passwd root
ln -s /lib/systemd/system/serial-getty\@.service /etc/systemd/system/getty.target.wants/serial-getty@ttyS0.service
apt install ifupdown net-tools
apt install udev
- 网络
下载sun8i-emac patch
dts添加：
&emac {
phy-handle = <&int_mii_phy>;
phy-mode = "mii";
allwinner,leds-active-low;
status = "okay";
}; -
移动硬盘
内核编译+USB MASS Storage支持
最后贴上fex文件和网卡patch:
