oes配置：A311D(六核RAM处理器)，RAM：4GB，ROM：8GB，三个2.5寸SATA硬盘位，一个USB接口，一个千兆网口，正是用做nas的好盒子。本文记录了刷机过程及踩过的坑。

线刷底包

安装USB_Burning_Tool，SECURE_BOOT_SET文件复制到USB_Burning_Tool安装目录下的license目录里，再打开软件，导入底包oesp1.img，取消右侧的选项。
oes拆机，拆散热片，短接点如图所示，

短接之后，用usb双公头线连接电脑和oes，插入oes电源，刷机工具提示连接成功即可松开短接。点击开始，等待进度条提示完成刷机。

短接刷机时注意，由于oes是独立电源，在短接不成功时，一定要先拔下usb线，再拔电源线，否则有电流冲击笔记本主板，可能导致电脑锁死。因为这个，轻薄本多次黑屏无响应，拆机拔电池排线才恢复。

安装飞牛

用rufus或balenaEtcher把官方刷机包img文件写入u盘，插入oes，接上电源，会从u盘启动飞牛系统，启动后从路由器后台找新加入设备的ip，用浏览器打开ip:5666，设置飞牛账号并打开账号的ssh权限。用创建的帐号ssh登入飞牛，运行

1 2	sudo -i ./install-to-emmc.sh

把u盘中的飞牛写入emmc。
