Abstract

The present disclosure relates to a firmware refresh method and device, belonging to the field of smart devices. The method includes: when the electronic device is in the startup stage, detecting whether the access device connected to the electronic device before the startup stage is a drive-free device; The update firmware is written in the electronic device; the update firmware written in the electronic device is run when the electronic device is in a normal operation stage after restarting. The present disclosure can solve the problem that the firmware in the professional flashing tool cannot be read when the corresponding driver is not installed in the electronic device, resulting in the failure of firmware flashing, and can simplify the firmware flashing process and improve the success rate of firmware flashing.

Description

technical field [0001] The present disclosure relates to the field of smart devices, in particular to a method and device for updating firmware. Background technique [0002] Firmware, as the most basic software in electronic equipment, ensures the normal operation of electronic equipment, but some external factors may cause firmware problems and affect the normal operation of electronic equipment. [0003] When there is a problem with the firmware of the electronic device, it is necessary to use a special brushing tool to refresh the firmware. When updating the firmware, usually a special flashing tool is connected to the electronic device, and the electronic device reads the firmware in the special flashing tool by running the driver program corresponding to the professional flashing tool, so as to refresh the original firmware. [0004] During the process of implementing the present disclosure, the discloser found that the above-mentioned method has at least the followin...
