上次已经开箱了，这次开机后看看有什么好玩的东东。开发板是用DC 5V来供电，但没有配电源适配器，作为开发板小达人，手里电源一大堆的，电源买多了也没什么用。上电前要确认BOOT Mode跳冒和Boot Dev拨码是否配置正确，具体可以参考官方的WiKi文档。从文档看官方是做了两个版本的，现在硬件更新到V2.1了。然后直接上电就可以了。下面是uboot启动信息，版本还是比较新的，

从启动信息上看，官方还是做了一些分区划分，具体用法还是看开发者了。文件系统是Yocto构建的，这个可以说是比较清新了，其它家的板子大都是buildroot，有些厂家还不提供buildroot的源码。SSH，DHCP都已经有了，可以更方便的折腾了。
