Abstract

The present invention is applicable to the field of network technology, and provides a firmware recovery method and device for network equipment, including: setting a factory recovery partition in the flash memory of the network device, and the factory recovery partition only supports read operations; the network device After power-on, the CPU of the network device starts to run from the factory recovery partition; trigger the factory recovery partition to enter the recovery mode; under the recovery mode, restore the firmware uploaded through the web page to the corresponding in the flash partition. When the firmware of the network device is damaged, the firmware recovery method provided by the present invention can avoid the situation that the network device cannot be successfully started, and can guide the user to complete the firmware repair of the network device through the recovery mode, reducing the number of rework and discarding of the network device. And speed up the repair speed of network equipment, improve production efficiency.

Description

technical field [0001] The invention belongs to the field of network technology, and in particular relates to a firmware recovery method and device for network equipment. Background technique [0002] The firmware of a home router usually includes a bootloader, an operating system, and an application program. When the device is powered on, the firmware is executed sequentially in the following manner: the CPU executes the bootloader, the bootloader initializes the hardware and boots the operating system, and the operating system loads the application. During the use of the home router, the firmware may be accidentally damaged, for example, the power is accidentally cut off during the firmware upgrade process, or incompatible cracked firmware is used, etc., which will cause the home router to fail to start normally. [0003] At present, in smart home routers, dual systems are introduced to solve the above problems. The firmware composition of the dual system usually includes...
