Abstract

The present invention refers to an embedded controller and updating firmware method. It contains said embedded controller being microprocessor type and with one firmware memory in notebook computer; said embedded controller having master / slave unit; before computer just powering on or I / O Controller Hub (ICH) action, said embedded controller changing embedded controller from slave unit into master device, this moment embedded controller capable of downloading part or whole firmware routine code from BIOS memory through LPC / SPI bus, through embedded type firmware internal circuit programming function to make part or all firmware updating, after updating embedded controller firmware, switching master device into slave unit, switching on notebook computer power supply or making I / O Controller Hub action.

Description

technical field [0001] The present invention relates to an embedded controller and a method for updating firmware thereof, in particular to an embedded controller that can effectively solve the problem of updating the firmware of the embedded controller corresponding to different versions of BIOS when manufacturing notebook computers and how to update the firmware. Background technique [0002] In a notebook computer (NB), there is an embedded controller (Embedded Controller, EC) used to control the keyboard, touch panel or other user interface, the embedded controller is generally implemented in the form of a microprocessor and With a firmware storage (Firmware Storage), there are currently two main circuits used to prepare the firmware storage, one is a shared memory circuit (SMS), and the other is an embedded memory circuit (EMS); Under the architecture of the memory circuit, such as figure 1 As shown, the embedded controller does not have a firmware memory, but shares ...
