Detailed Description
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the embodiments described below are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
For the convenience of understanding the present solution, the application scenario and some terms of the present solution are briefly introduced here:
the invention provides a firmware updating scheme which can be applied to updating of firmware in any electronic equipment. For convenience of explanation, the following describes a scheme of the present invention by taking a Type-C interface of a notebook computer as an example.
The Type-C interface is one of USB interfaces, can realize not dividing arbitrary the inserting of positive and negative two sides, and the wide application is in various electronic equipment now. The PD is a quick charging technology, if interfaces with PD functions are arranged on the mobile phone, the tablet and the notebook computer, bidirectional transmission of power supply and power receiving can be realized, and therefore mutual sharing of electric energy among the mobile phone, the tablet and the notebook computer is realized; PD technology is now being used in Type-C interfaces, which need to be upgraded or repaired during use.
The Basic Input Output System (BIOS) is a set of programs stored in a rom on a terminal motherboard, including a Basic Input Output program, a self-test program after power-on, a System self-start program, and the like, which are most needed by a terminal, and is one of the bases of the terminal.
An Embedded Controller (EC) is a control system for performing a specified independent control function and having a complex data processing capability, and for example, an EC in a notebook computer can be used to control a built-in mouse, keyboard, and the like.
The following further describes the technical solution of the present invention by taking updating a Type-C interface with a PD function as an example and by a specific implementation manner with reference to the accompanying drawings.
Referring to fig. 1 and fig. 2 in combination, an embodiment of the invention provides a firmware updating method; in this embodiment, the update method is described by taking an example of updating the PD function of the Type-C interface, and therefore the firmware is the firmware of the PD chip connected to the Type-C interface.
Specifically, the firmware updating method includes:
s1, acquiring a target update version;
s2, searching the firmware to be updated based on the target update version;
s3, for each searched firmware to be updated, executing: and generating an update file according to the target update version, and burning the update file into the firmware to be updated.
The steps S1 and S2 may be implemented by a bios, which is used to detect whether there is upgrade or update in the system, so as to detect whether version update information is currently received, and when the version update information is detected, obtain a target update version based on the version update information.
Further, the basic input output system searches the firmware to be updated based on the target update version, searches the firmware of which the current version is inconsistent with the target update version based on the target update version, and determines the searched firmware as the firmware to be updated. When the current version of the firmware is inconsistent with the target update version, the current version of the firmware is not the latest version and needs to be subjected to version update.
It is understood that, when a plurality of firmware to be updated are searched, the firmware to be updated may be updated in sequence.
Further, in step S3, burning the update file into the firmware to be updated includes:
acquiring a firmware identifier of a firmware to be updated, and generating a corresponding updating command according to the firmware identifier; and issuing the update command and the update file to the PD chip corresponding to the firmware identifier through the embedded controller, so that the PD chip stores the update file to the corresponding firmware to be updated. The updating command is specifically cmd, and the updating file is specifically the quantile data of the PD chip to be burned.
It can be understood that the bios sends an update command through the embedded controller to notify the embedded controller to update the sub-bits of the corresponding PD chip. Therefore, when the embedded controller receives the update command, other actions on the bus connected with the corresponding PD chip are stopped to prepare for updating the firmware to be updated.
After the embedded controller prepares for updating the firmware to be updated, the basic input and output system writes the update file into the embedded controller, the embedded controller writes the update file into the PD chip to update the sub-position of the PD chip and issues an update command to the PD chip, so that the PD chip writes the update file into the corresponding position of the firmware.
After the burning of the updated firmware is finished, generating feedback information, and uploading the feedback information to a basic input and output system through a PD chip and an embedded controller layer; the basic input and output system receives feedback information; and judging whether the feedback information corresponds to the target update version.
It can be understood that, when the feedback information does not correspond to the target update version, it indicates that the update file burned by the firmware to be updated does not correspond to the target update version, i.e., the burning of the firmware to be updated fails.
When the burning of the firmware to be updated fails, the following steps are executed again: generating an update file according to the target update version, and burning the update file into the firmware to be updated; and after the firmware burning is finished, receiving the feedback information of the firmware to be updated after the firmware burning is finished again, and judging whether the feedback information corresponds to the target update version or not until the feedback information corresponds to the target update version.
Referring to fig. 2, based on the foregoing embodiment, the present invention further provides a firmware updating apparatus, including a bios 10 and an embedded controller 20, where the embedded controller 20 is connected to a plurality of firmware through an I2C bus (Inter-Integrated Circuit, bi-directional two-wire synchronous serial bus).
It is understood that, in the present embodiment, the PD function of the Type-C interface is described as an example, and therefore the firmware is the firmware of the PD chip 30 connected to the Type-C interface.
In this embodiment, the bios 10 is configured to detect whether version update information is received; when the version updating information is detected, acquiring a target updating version based on the version updating information; the bios 10 is further configured to search the firmware 31 to be updated from the plurality of firmware based on the target update version, and generate an update file according to the target update version.
The embedded controller 20 is configured to burn the update file into the firmware to be updated 31 for each searched firmware to be updated 31.
Further, the bios 10 is configured to search for firmware whose current version is inconsistent with the target update version based on the target update version, and determine the searched firmware as the firmware to be updated 31.
In addition, the bios 10 is further configured to obtain a firmware identifier of the firmware 31 to be updated, generate a corresponding update command according to the firmware identifier, and issue the update command to the embedded controller 20, so as to update the firmware 31 to be updated.
When the embedded controller 20 receives the update command, all actions on the I2C bus connected to the PD chip 30 on which the firmware 31 to be updated is located are stopped to enter the update waiting state. The bios 10 then writes the update file into the embedded controller 20, and the embedded controller 20 writes the update file into the PD chip 30 and issues an update command onto the PD chip 30, so that the PD chip 30 writes the update file into a corresponding location of the firmware 31 to be updated.
After the update file is generated in the target update version and burned into the firmware 31 to be updated, the firmware 31 to be updated sends feedback information to the PD chip 30, and the feedback information is uploaded to the bios 10 via the embedded controller 20.
The bios 10 receives feedback information after burning the firmware 31 to be updated, and determines whether the feedback information corresponds to the target update version; when the feedback information does not correspond to the target update version, the bios 10 issues the update command and the update file to the embedded controller 20 again to achieve re-burning of the firmware to be updated 31.
Based on the foregoing embodiments, the present invention also provides an electronic device, including:
a memory for storing a program;
a processor for implementing the steps of the firmware updating method as any one of the above when executing the program.
The above-mentioned embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the same; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
