进入bootroom菜单清除Console密码

通过console线和crt软件连接并登陆设备，然后把设备断电重启。控制台上会打印如下信息，当出现“press Ctrl+B”的时候快速按住“Ctrl+B” 进入botroom菜单

System is starting...
Press Ctrl+D to access BASIC-BOOTWARE MENU

BootWare Validating...
Press Ctrl+B to enter extended boot menu...

BotWare password: Not required. Please press Enter to continue.

Password recovery capability is enabled.

Note: The current operating device is flash

Enter < Storage Device Operation > to select device.

按住“Ctrl+B”进入如下菜单。选择“<6> Skip Current System Configuration”跳过当前配置启动,不同设备可能不是数字6，
