系统固件分为三种
- factory 从默认固件刷OpenWRT时使用，即第一次刷第三方固件时使用
- sysupgrade 已经刷OpenWRT了，需要更新版本时使用
- tftp 设备刷故障了，使用tftp方式恢复时，需要特别使用这个固件
刷机方式有二种
- mtd
mtd -e linux -r write gargoyle_1.3.14-ar71xx-wzr-hp-g300nh-squashfs-sysupgrade.bin linux
mtd -r write openwrt-ar71xx-wzr-hp-g300nh-squashfs-sysupgrade.bin linux
- sysupgrade
sysupgrade -v /tmp/openwrt-ar71xx-generic-wzr-hp-ag300h-squashfs-sysupgrade.bin
Installation Procedure
Change firmware name
修改openwrt-ar71xx-wzr-hp-g300nh-squashfs-sysupgrade.bin为1.bin，方便文件传输和操作
本地运行HFS HTTP Server，指向目录到bin文件upload firmware
cd /tmp
wget http://172.16.230.132/1.bin-
Write firmware
mtd -r write 1.bin firmware官方操作文档需要将文件写入到linux下：
mtd -r write openwrt-ar71xx-wzr-hp-g300nh-squashfs-sysupgrade.bin linux
但实际操作时可能没有，则需要自己去检查：
cat /proc/mtd Real Case
操作实例：
root@Gargoyle:~# cd /tmp/
root@Gargoyle:/tmp# wget http://172.16.230.132/1.bin

- Setup
刷机完成后，无线信号默认是不开启的（刷成砖的场景除外），需要连接网线到LAN进行配置。
Gargoyle 默认密码：root/password
（1） 配置自定义端口号
https: 3911
ssh: 3912
（2）配置LED
Vim /etc/config/system
config 'led' 'Wan'
option 'name' 'Wan'
option 'sysfs' 'buffalo:green:router'
option 'trigger' 'netdev'
option 'dev' 'pppoe-wan'
option 'mode' 'link'
config 'led' 'Diag'
option 'name' 'Diag'
option 'sysfs' 'buffalo:red:diag'
option 'trigger' 'none'
option 'default' '0'
config 'led' 'Wlan'
option 'name' 'Wlan'
option 'sysfs' 'ath9k-phy0'
option 'trigger' 'netdev'
option 'dev' 'wlan0'
option 'mode' 'link'
