Image Generator (Image Builder) - OpenWrt Wiki 沿途见识[2]

5.使用说明
make image命令会创建一个只包含必不可少包文件的最小化镜像，这个命令可以通过三个传递过去的参数控制:

PROFILE - 指定要编译的目标镜像的配置
PACKAGES - 要嵌入镜像的包文件的列表
FILES - 要包含进去的自定义文件的目录


6.编译
make image PROFILE=XIAOMI-MIWIFI-MINI PACKAGES="luci luci-i18n-base-zh-cn luci-i18n-ddns-zh-cn luci-i18n-hd-idle-zh-cn luci-i18n-samba-zh-cn luci-i18n-upnp-zh-cn luci-i18n-qos-zh-cn luci-i18n-wol-zh-cn luci-i18n-p910nd-zh-cn luci-i18n-samba-zh-cn luci-i18n-openvirtual**-zh-cn ppp-mod-pptp ppp-mod-pppoa comgt xl2tpd kmod-usb-printer kmod-usb-storage kmod-usb-ohci kmod-usb2 kmod-usb-uhci kmod-usb-serial kmod-usb-serial-ftdi kmod-usb-acm block-mount mount-utils kmod-fs-ntfs kmod-fs-ext4 kmod-fs-vfat kmod-nls-utf8 kmod-nls-cp437 kmod-nls-iso8859-1 ntfs-3g usbutils luci-i18n-transmission-zh-cn kmod-video-uvc kmod-usb2 kmod-video-core luci-app-mjpg-streamer"

在make命令结束后，生成的镜像会被放到bin目录中。

ll bin/ramips

8.刷生产openwrt的rom

8.1 通过miwifi.com页面刷回 系统版本: 0.7.15 开发版  我的小米mini的MAC地址: 64:09:80:06:45:5A
miwifi_r1cm_all_02508_0.7.15.bin

查看固件分区

即可完成LUCI的安装。
输入以下命令开启支持web服务的uhttpd，并设置其为自启动：
Shell代码  
/etc/init.d/uhttpd enable # 开机自启动  
/etc/init.d/uhttpd start # 启动uhttpd


玩坏路由如何恢复
http://bbs.xiaomi.cn/thread-10512768-1-1.html
【操作流程】

阅读特别提示并确认备份已经完成后，请按照以下步骤操作：

1、请将下载的工具包bin文件复制到U盘的根目录，点此进入最新Rom下载页面
2、将U盘里的bin文件重命名为 miwifi.bin
3、断开小米路由器mini的电源，将U盘插入USB接口
4、按下reset按钮后重新接入电源，指示灯变为黄色闪烁状态后松开reset键
5、整个u盘刷机的时间相比正常OTA升级更长一些，因为这种刷机方式会将小米路由器mini的系统重新刷一遍
6、刷机完成之后系统会自己重启并进入正常的启动状态（黄灯常亮—蓝灯常亮）
7、如果出现异常/失败/U盘无法读取状态，会进入红灯状态，建议重试或更换U盘再试8、正常启动显示蓝灯，完成刷机！

不知道OpenWrt官方的这个稳定性怎么样

补充下原来编译固件存在问题：openvirtual**不能启用
解决原因是你还没有安装openvirtual**就安装他的luci当然不能用，你要先opkg install openvirtual**-openssl openvirtual**-easy-rsa
再opkg install luci-app-openvirtual** luci-i18n-openvirtual**-zh-cn
