[0002] If the software of the home gateway device is abnormal during use, it may be impossible to restore the normal operation of the device through web upgrade system or Telnet (remote terminal protocol) operation methods
However, if the current home gateway device does not have a serial port pin, even if the hardware is intact, the device cannot be used when the software is abnormal, and the customer has to replace it with a new device, which brings significant cost waste.

Embodiment Construction
[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0034] see figure 1 As shown, the present invention provides a kind of method that home gateway enters safe mode, and it is based on Linux embedded operating system, and this method comprises the following steps:
[0035] S1. Initialize the single board parameters of the home gateway;
[0036] S2. Initialize the network device interface driver;
[0037] In an embedded operating system, BootLoader (bootloader) runs before the operation of the operating system kernel. It can initialize hardware devices and establish a memory space map, thereby bringing the system's hardware and software environment to a suitable state for the final call operation. The system kernel prepares the correct environment.
[0038] Since it is necessary to access the web page after entering the safe mode, entering the safe mode must be at the stage after the BootLoader has completed...

The invention discloses a safe mode entering mode of a household gateway and a household gateway system, and relates to the field of household gateway equipment. The method based on a Linux embedded operating system comprises the following steps that a single-board parameter of the household gateway is initialized; an interface driver of network equipment is initialized; and whether a peripheral indicating lamp button of the household gateway is pressed is determined, if NO, the Linux embedded operating system is started, and if YES, start of the Linux embedded operating system is delayed and whether a peripheral reset button of the household gateway is pressed is determined, the Linux embedded operating system is started if the reset button is not pressed, and otherwise, whether the reset button is pressed continuously till a designed time length is determined further, the Linux embedded operating system is started if the reset button is not pressed continuously till the designed time length, and the household gateway enters a safe mode if the reset button is pressed continuously till the designed time length. The method can recover normal operation of the household gateway equipment, the maintenance cost is reduced, and the method is easy to operate and realize.
Description
technical field [0001] The invention relates to the field of home gateway equipment, in particular to a method for a home gateway to enter a security mode and a home gateway system. Background technique [0002] If the software of the home gateway device is abnormal during use, it may be impossible to restore the normal operation of the device through web upgrade system or Telnet (remote terminal protocol). However, if the current home gateway device does not have a serial port pin, even if the hardware is intact, the device cannot be used when the software is abnormal, and the customer must be replaced with a new device, which brings significant cost waste. Contents of the invention [0003] For the defects existing in the prior art, the purpose of the present invention is to provide a method for a home gateway to enter a safe mode, which allows the home gateway device to perform system software upgrades to restore the normal operation of the home gateway device when it e...
