Cisco AP-ROMMON升级AP镜像

Rommon is Cisco bootloader for their Router devices >>>ROMMON是思科设备的引导加载程序
while U-boot is a very generic bootloader for lots of embedded device >>>u-boot是许多嵌入式设备的非常通用的引导程序
both U-boot and Rommon support tftp >>>>他们都支持tftp
U-boot Support sntp nfs while Rommon dont >>>u-boot还支持sntp nfs但ROMMON不支持

ROMMON升级AP镜像

1. ap:format flash: #格式化AP的flash.
2. 使用AP ROMON 模式进行重新转换镜像， 可以使用2种方法进入ROMON模式，
1）插上console线，断掉电源， 按住AP mode button之后接上电源，等待屏幕出现release button into ROMMON，松开mode键进入ROMMON模式.
2）重启AP之后重复按esc键进入ROMMON 模式. 之后，使用如下命令进行镜像升级或转换，
ap: ether_init
ap: flash_init
ap: tftp_init
ap: set IP_ADDR
ap: set NETMASK
ap: set DEFAULT_ROUTER

ap: tar -xtract tftp://< server ip address >/< image name > flash:
ap: boot flash:/< image dir >/< image name >

3.重新加载镜像。

操作示例：

ap: arp
255.255.255.255 ff:ff:ff:ff:ff:ff 0 160

ap: set IP_ADDR 10.0.0.9

ap: set NETMASK 255.255.255.0

ap: set DEFAULT_ROUTER 10.0.0.10 <<<<<AP直连的笔记本网口，网关就直接配置了笔记本网口的IP了。

ap: tar -xtract tftp://10.0.0.10/ap3g1-k9w7-tar.default flash:

注意：一般这种情况下，我们看到的是一个文件夹，实际的文件在改文件夹下：

由于我们没有AP之前的启动image还在，所以，目前启动的话，可能还是按原来的镜像启动，所以我们把原来的镜像删掉：

ap: delete flash:/ap3g1-k9w8-mx.153-3.JD16/ap3g1-k9w8-xx.153-3.JD16
Are you sure you want to delete "flash:/ap3g1-k9w8-mx.153-3.JD16/ap3g1-k9w8-xx.153-3.JD16" (y/n)?y
File "flash:/ap3g1-k9w8-mx.153-3.JD16/ap3g1-k9w8-xx.153-3.JD16" deleted

ap3g1-k9w8-mx.153-3.JD16文件也删掉！

然后查看一下：

ap: dir flash:/ap3g1-k9w8-mx.153-3.JD16
Directory of flash:/ap3g1-k9w8-mx.153-3.JD16/

或者也可以使用ap：下使用命令：Fsck flash: 来格式化Flash之后再传需要升级的镜像，因为ap:模式下本来就是为了在flash被格式化了来恢复AP的。

启动新的镜像：

ap: boot flash:/ap3g1-k9w7-mx.153-3.JF10/ap3g1-k9w7-mx.153-3.JF10
