Abstract
The present invention provides a firmware update method and system, wherein the method is applied to an embedded controller chip, the embedded controller chip includes: a default decoding port and a first storage device, the first storage device is used to store a default decoding address corresponding to the default decoding port, and the embedded controller chip is connected to a host through a system bus for communication; the method includes: obtaining a base address and a default decoding address of the system bus, and obtaining a mapping address according to the base address and the default decoding address; mapping the default decoding port to a host storage device through the mapping address, so that the default decoding address forms a mapping relationship with the port address of the host storage device, and the host communicates with the default decoding port corresponding to the default decoding address through the mapping address stored in the host storage device; obtaining an update instruction by monitoring the first storage device; and updating the firmware according to the update instruction. The present invention can improve the efficiency of firmware updates.
