Abstract
The invention discloses an updating method for a firmware of an embedded controller. The firmware of the embedded controller comprises a computer system. The computer system is provided with an input / output system and an operating system. The updating method comprises the following steps: providing the embedded controller firmware to be used as a part of the input / output system; providing a flash memory to be used as a part of the input / output system; starting the computer system, and writing an updating algorithm of a new firmware and a new embedded controller into the flash memory in the process of start; and restarting the computer system so that the input / output system operates the updated algorithm, and writing the new firmware into a storage area of the embedded controller. By means of the updating method for the firmware of the embedded controller, updating of the firmware is convenient, and termination of a programming process of an embedded system due to emergencies of the system can be further avoided.
Description
Technical field
The present invention relates to computer realm, relate in particular to a kind of embedded controller firmware update.
Background technology
Current known embedded system is widely used, yet also presented many shortcomings, for example, the firmware renewal process is complicated, if the processing procedure that a system firmware is stored in non-volatile flash memory or ROM is interrupted prematurely or stopped, or running into outage midway makes the system need not energy.
Summary of the invention
Embodiment of the present invention technical matters to be solved is, a kind of embedded controller firmware update is provided.Can conveniently upgrade firmware, can also prevent that embedded system from stopping the programmed process process because of system's emergency.
In order to solve the problems of the technologies described above, the embodiment of the present invention provides a kind of embedded controller firmware update, comprise computer system, described computer system has input/output and operating system, and the method comprises the following steps: the part of embedded controller firmware as input/output is provided; The part of a flash memory as input/output is provided; Start described computer system, in start-up course, and the update algorithm of a new firmware and embedded controller is write in flash memory; Restart computer system, described input/output operation update algorithm writes new firmware in memory block in embedded controller.
Implement the embodiment of the present invention, have following beneficial effect: can conveniently upgrade firmware, can also prevent that embedded system from stopping the programmed process process because of system's emergency.
Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, below the present invention is described in further detail.
A kind of embedded controller firmware update of the present invention comprises computer system, and described computer system has input/output and operating system, and the method comprises the following steps: the part of embedded controller firmware as input/output is provided; The part of a flash memory as input/output is provided; Start described computer system, in start-up course, and the update algorithm of a new firmware and embedded controller is write in flash memory; Restart computer system, described input/output operation update algorithm writes new firmware in memory block in embedded controller.
