Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
Referring to fig. 1 and fig. 2, an electronic device 10 is provided in an embodiment of the present application, where the electronic device 10 may be a communication device such as a router, a switch, a gateway, a network bridge, or the like, a user terminal such as a smart phone, a tablet computer, a digital music player, or the like, and a server such as a web server, a database server, a cloud server, or a server cluster composed of multiple sub-servers.
In this embodiment, the electronic device 10 may include: the electronic device includes a core processor 11 and a functional chip 12 connected to the core processor 11, where the core processor 11 may be a chip with relatively high processing performance, such as a CPU (central processing Unit), an MCU (micro controller Unit), and the type and number of the functional chip 12 may be selected according to the functional requirement of the electronic device 10. The core processor 11 and the functional chip 12 may be provided on a motherboard 13 of the electronic device 10, and the core processor 11 and the functional chip 12 may be connected by a bus 14 provided on the motherboard 13. In addition, the main board 13 of the electronic device 10 is further provided with a memory 15 of the electronic device 10, for storing the BOOT program required by the core processor 11.
In this embodiment, the BOOT program carries the latest firmware required by the functional chip 12 and the latest firmware version, in addition to the relevant programs required by the core processor 11. After the core processor 11 is powered on, the core processor 11 may call and execute the BOOT program. During the execution of the BOOT program, the core processor 11 can update the firmware running on the functional chip 12 by using the latest firmware of the functional chip 12 in the BOOT program and the latest version of the latest firmware, thereby achieving the automatic completion of the whole firmware update process.
The update process of the firmware will be described in detail below by way of an embodiment of the method.
Referring to fig. 3, an embodiment of the present application provides methods for updating firmware, where the methods for updating firmware can be executed by the core processor 11, and the methods for updating firmware can include:
step S100: the latest firmware of the functional chip and the version of the latest firmware are acquired.
Step S200: and updating the original BOOT program of the core processor, which does not carry the latest firmware and the version of the latest firmware, by using the latest firmware and the version of the latest firmware to obtain the BOOT program carrying the latest firmware and the version of the latest firmware.
Step S300: and in the process of running the updated BOOT program, acquiring the version of the firmware running on the functional chip and acquiring the version of the latest firmware carried in the updated BOOT program.
Step S400: it is determined whether the version of the latest firmware is the same as the version of the running firmware.
Step S500: if not, updating the running firmware by using the latest firmware carried in the updated BOOT program, otherwise, not updating the running firmware.
The following describes steps S100 to S500 in detail with reference to examples.
Step S100: the latest firmware of the functional chip and the version of the latest firmware are acquired.
When the firmware on the functional chip 12 needs to be updated by using the latest firmware or the latest firmware needs to be written into the functional chip 12 which is not provided with the firmware, the original BOOT program of the core processor 11 may be updated by using the latest firmware and the version of the latest firmware to obtain the BOOT program carrying the latest firmware and the version of the latest firmware, where the original BOOT program does not carry the latest firmware and the version of the latest firmware.
th exemplary way to update the original BOOT program:
the developer can directly write the latest firmware, the version of the latest firmware, and the addresses of the latest firmware and the version of the latest firmware in the BOOT program to the core processor 11. The core processor 11 receives the latest firmware, the latest firmware version, and the addresses of the latest firmware and the latest firmware version in the BOOT program.
As a second exemplary way to update the original BOOT program:
developers can obtain the backup of the original BOOT program, so that the original BOOT program is edited, the latest firmware, the version of the latest firmware and the address of the latest firmware and the version of the latest firmware in the BOOT program are directly written into the corresponding position corresponding to the address in the original BOOT program, and the updated BOOT program carrying the latest firmware, the version of the latest firmware and the address of the version of the latest firmware and the latest firmware is obtained. It should be noted that, if there is data already at the corresponding location, the latest firmware and the version of the latest firmware overwrite the existing data at the corresponding location.
In this way, the developer can directly write the updated BOOT program to the core processor 11. The core processor 11 receives the updated BOOT program carrying the latest firmware, the latest firmware version, and the addresses of the latest firmware and the latest firmware version.
Referring to fig. 4, the data structure of the updated BOOT program may be, for example, as shown in fig. 4, assuming that the core processor 11 executes the updated BOOT program from left to right, and starting from left, th data in the updated BOOT program may be the BOOT program itself, so as to ensure normal execution of the updated BOOT program by the core processor 11, then each data from the right to the left may be the addresses of the latest firmware, the latest firmware version, and the latest firmware version of each functional chip 12, and the addresses of the latest firmware, the latest firmware version, and the latest firmware version of each functional chip 12 are located in separate boxes in the diagram, in other words, the addresses of the latest firmware, the latest firmware version, and the latest firmware version of each functional chip 12 occupy separate parts in the updated BOOT program.
Continuing with FIG. 4, it should be noted that, since the programs in the updated BOOT program are arranged in order, the address of the latest firmware can be represented by data size, for example, if the number of the BOOT programs in the BOOT program is XXXMB, then the address of the th latest firmware from left to right in the BOOT program can be represented by XXXMB, if the number of the th latest firmware is YYMB, then the address of the second latest firmware from left to right in the BOOT program can be represented by XXXMB + YYMB, and so on.
Step S200: and updating the original BOOT program of the core processor, which does not carry the latest firmware and the version of the latest firmware, by using the latest firmware and the version of the latest firmware to obtain the BOOT program carrying the latest firmware and the version of the latest firmware.
When the aforementioned method is used, the core processor 11 may find the corresponding location corresponding to the address in the original BOOT program according to the latest firmware and the address of the version of the latest firmware in the BOOT program, and write the latest firmware, the version of the latest firmware, and the address of the version of the latest firmware and the latest firmware into the corresponding location in the original BOOT program, thereby obtaining the updated BOOT program.
When the second method is adopted, the core processor 11 may replace the original BOOT program with the updated BOOT program to obtain the updated BOOT program.
After obtaining the updated BOOT program, the core processor 11 may execute step S300 further .
Step S300: and in the process of running the updated BOOT program, acquiring the version of the firmware running on the functional chip and acquiring the version of the latest firmware carried in the updated BOOT program.
This updated BOOT program may be stored by the core processor 11 into the memory 15, for example into a hard disk, or into a size area of the core processor 11 itself. When the core processor 11 is powered on and started, the core processor 11 may call the updated BOOT program from the memory 15, load the updated BOOT program into the memory of the electronic device 10, and run the updated BOOT program.
With the running of the updated BOOT program, the core processor 11 may obtain, based on the instruction in the BOOT program, the version of the firmware running on the functional chip 12 from the functional chip 12. In addition, when the updated BOOT program runs to the latest firmware, the version of the latest firmware, and the part where the addresses of the latest firmware and the version of the latest firmware are located, the core processor 11 acquires the version of the latest firmware.
Step S400: it is determined whether the version of the latest firmware is the same as the version of the running firmware.
To ensure a correct update of the firmware of the functional chip 12, the core processor 11 may determine whether the version of the latest firmware is the same as the version of the running firmware. The same indicates that the firmware running on the functional chip 12 does not need to be updated, and the other indicates that the firmware running on the functional chip 12 needs to be updated to the latest firmware.
Note that, if the functional chip 12 does not have firmware yet, the version of the operating firmware acquired by the core processor 11 is null. If the firmware version is empty, the core processor 11 may determine whether the latest firmware version is the same as the running firmware version.
Step S500: if not, updating the running firmware by using the latest firmware carried in the updated BOOT program, otherwise, not updating the running firmware.
If the latest firmware version is determined to be different from the running firmware version, the core processor 11 may start the firmware updating process.
Specifically, since the updated BOOT program is loaded into the memory, the core processor 11 may obtain an address of the updated BOOT program in the memory (the address of the updated BOOT program in the memory is used to indicate a location of the updated BOOT program in the memory). Thus, the core processor 11 can determine the address of the latest firmware in the memory by adding the address of the updated BOOT program in the memory to the address of the latest firmware in the BOOT program, where the address of the latest firmware in the memory is used to accurately find the latest firmware in the memory.
Further , the core processor 11 may obtain the latest firmware from the memory according to the address of the latest firmware in the memory and transmit the latest firmware to the functional chip 12 so that the functional chip 12 can update with the latest firmware, or the core processor 11 may directly transmit the address of the latest firmware in the memory to the functional chip 12 so that the functional chip 12 requests the latest firmware from the core processor 11 according to the address of the latest firmware in the memory so that the core processor 11 transmits the latest firmware to the functional chip 12 in response to the request of the functional chip 12 so that the functional chip 12 can update with the latest firmware.
If it is determined that the latest firmware version is the same as the running firmware version, the core processor 11 may terminate the execution of the firmware update procedure.
Furthermore, in implementations of the embodiment, to ensure that the firmware can be updated normally, after determining that the version of the latest firmware is the same as the version of the firmware running on the functional chip 12 and before updating the firmware running on the functional chip 12 with the latest firmware carried in the BOOT program, the core processor 11 may further determine the size of the latest firmware and determine whether the size of the latest firmware is within a preset threshold size.
Specifically, if the address of the latest firmware is represented by the data size, the core processor 11 may obtain the addresses of the next firmware neighboring the latest firmware in the BOOT program, and determine the difference between the address of the latest firmware in the BOOT program and the address of the next firmware in the BOOT program, where the difference is used to represent the size of the latest firmware.
Of course, the size of the latest firmware is determined so that the core processor 11 can subsequently perform operations such as file Check, CRC (Cyclic Redundancy Check) calculation, etc. on the latest firmware to ensure that the latest firmware is fully available.
At step , after determining the size of the latest firmware, the core processor 11 may determine whether the size of the latest firmware is within a threshold size.
If the size of the latest firmware is determined to be within the threshold size, the size of the latest firmware is indicated to be normal, and updating can be carried out. The core processor 11 can thus continue to execute the related flow of updating the firmware running on the functional chip 12 with the latest firmware carried in the BOOT program.
If the size of the latest firmware is determined to exceed the threshold size, it indicates that the latest firmware is not normal in size, which may cause an update error or failure. Then the core processor 11 does not update the firmware running on the functional chip 12.
Referring to fig. 5, based on the same inventive concept as , the embodiment of the present application further provides a firmware updating apparatus 100, where the firmware updating apparatus 100 is applied to the core processor 11, and the firmware updating apparatus 100 may include:
the data obtaining module 110 is configured to obtain the latest firmware of the functional chip 12 and the version of the latest firmware.
The program updating module 120 is configured to update the original BOOT program of the core processor 11, which does not carry the latest firmware and the version of the latest firmware, with the latest firmware and the version of the latest firmware, and obtain the BOOT program carrying the latest firmware and the version of the latest firmware.
The data obtaining module 110 is further configured to, in the process of running the updated BOOT program, obtain the version of the firmware running on the functional chip 12, and obtain the version of the latest firmware carried in the updated BOOT program.
The firmware update module 130 is configured to determine whether the version of the latest firmware is the same as the version of the running firmware. If not, updating the running firmware by using the latest firmware carried in the updated BOOT program, otherwise, not updating the running firmware.
