Abstract

The invention belongs to the technical field of networks, and provides a firmware recovery method and device of network equipment. The method includes the steps that a factory leaving recovery partition is set in a flash memory of the network equipment, and the factory leaving recovery partition only supports read operation; after the network equipment is powered up, a CPU of the network equipment starts running from the factory leaving recovery partition; the factory leaving recovery partition is triggered to enter in a recovery state; firmware uploaded through a web page is recovered into the flash memory partition corresponding to the firmware in the recovery mode. When the firmware of the network equipment is damaged, the firmware recovery method can avoid the phenomenon that the network equipment cannot be started successfully, firmware repair of the network equipment can be guided to be achieved by users in the recovery mode, the number of rework and the abandoned phenomenon of the network equipment are reduced, the repair speed of the network equipment is decreased, and the production efficiency is improved.

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...
