[0002] Currently, when the programs of different power embedded terminals are iterating versions, they all need to be updated through the BIOS (Basic Input / Output System). Generally speaking, there is a running program in a power embedded terminal, and different types of power embedded terminals run different types of programs. Therefore, when different types of power embedded terminals iterate versions (upgrade or update), different BIOS configurations are required. This results in non-fixed processes and non-fixed parameters for BIOS configurations of different types of devices, and it is not convenient to transplant. Summary of the Invention

[0003] Embodiments of this application provide a method, module, terminal, and storage medium for upgrading the program of a power embedded terminal, so that the same BIOS can be applicable to upgrading the programs in multiple types of power embedded terminals.

[0004] This application is implemented through the following technical solutions:

[0005] In a first aspect, embodiments of this application provide a method for upgrading the program of a power embedded terminal, which is applied to the BIOS for a power embedded terminal. A upgradable program runs in the power embedded terminal, and the BIOS includes multiple program upgrade processes. The method includes:

[0014] If the program upgrade data is complete and correct upgrade data, erase the program in the target device and write all the program upgrade data into the target device.

[0015] If the program upgrade data is not complete and correct upgrade data, perform a CRC check on the program in the target device; if the program in the target device is complete and correct data, execute the original program; if the program in the target device is not complete and correct data, re-obtain the program upgrade data.

[0016] In combination with the first aspect, in some possible implementation manners, performing a CRC check on the program upgrade data to determine whether the program upgrade data is complete and correct upgrade data includes:

[0017] Based on a preset generation polynomial, perform an exclusive OR operation on the program upgrade data in binary to obtain a first CRC check value.

[0018] If the CRC check value stored in the check bit in the program upgrade data is the same as the first CRC check value, the program upgrade data is complete and correct upgrade data.

[0019] In combination with the first aspect, in some possible implementation manners, the preset generation polynomial includes: CRC-8 generation polynomial, CRC-16 generation polynomial, CRC-32 generation polynomial, CRC-64 generation polynomial, or CRC-CCITT generation polynomial.

[0020] In combination with the first aspect, in some possible implementation manners, writing all the program upgrade data into the target device includes:

[0021] Divide the program upgrade data into multiple consecutive sub-data sets.

[0022] Write the multiple consecutive sub-data sets in sequence.

[0023] For each sub-dataset, after the writing of the sub-dataset is completed, obtain the content corresponding to the sub-dataset in the target device at this time; if the program corresponding to the sub-dataset in the target device at this time is exactly the same as the sub-dataset, the data comparison of the sub-dataset is correct, and if the content corresponding to the sub-dataset in the target device at this time is not exactly the same as the sub-dataset, the data comparison of the sub-dataset is incorrect, and the writing of the sub-dataset is restarted. If the number of times the data comparison of the sub-dataset is incorrect exceeds the preset threshold, the upgrade is restarted.

[0024] If the data comparison of all sub-datasets is correct, the upgrade of the target device program is completed.

[0025] Combined with the first aspect, in some possible implementation manners, the method further includes:

[0026] After the upgrade of the target device program is completed, update the program running parameters of the target device at this time; wherein, the updated program running parameters will not cause the target device to be upgraded again.

[0027] In a second aspect, an embodiment of the present application provides a power embedded terminal program upgrade module, including:

When the program needs to be upgraded, it can determine the target upgrade process corresponding to the target device from multiple program upgrade processes according to the program configuration, and upgrade the program in the target device using the program upgrade data according to the target upgrade process. Compared with the traditional BIOS, the BIOS of the present application can be applied to upgrade the programs in various types of power embedded terminals, making the BIOS applicable to more scenarios. When the BIOS is transplanted and used, only the configuration and underlying drivers of the BIOS itself need to be modified, without caring about the problems of the update program process and logic.

[0047] The reference to "one embodiment" or "some embodiments" etc. described in the specification of the present application means that a specific feature, structure, or characteristic described in connection with that embodiment is included in one or more embodiments of the present application. Thus, statements such as "in one embodiment", "in some embodiments", "in other some embodiments", "in still other embodiments", etc. that appear in different places in this specification do not necessarily all refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways.

[0048] The embodiments of the present application provide a method for upgrading a power embedded terminal program, which is applied to a standardized BIOS including multiple program upgrade processes, and one program runs in one power embedded terminal.Figure 1 It is a schematic flowchart of a method for upgrading a power embedded terminal program provided by an embodiment of the present application. Referring to Figure 1 , the detailed description of the method for upgrading the power embedded terminal program is as follows:

[0049] Step 101: Obtain the program upgrade data, program running parameters, and program configuration of the target device; where the target device is any power embedded terminal.

[0050] Step 102: Based on the program upgrade data and program running parameters, determine whether the target device needs to upgrade the program.

[0051] Exemplarily, if the data in the program upgrade data and the program running parameters conform to the upgrade logic of the standardized BIOS, that is, the upgrade times data in the upgrade data is 0x0101 more than the upgrade times data in the running parameters, the target device needs to upgrade the program.

[0052] Step 103: If the target device needs to upgrade the program, based on the program configuration, determine the target upgrade process corresponding to the target device from multiple program upgrade processes.

[0053] Exemplarily, there is a flag in the program configuration representing the type of this device. Therefore, the type of the target device can be directly determined through the program running parameters, and then the target upgrade process corresponding to the target device can be determined.

[0054] Step 104: Based on the target upgrade process, use the program upgrade data to upgrade the program in the target device.

[0055] Exemplarily, using the program upgrade data to upgrade the program in the target device may include:

[0056] Erase the program in the target device and write all the program upgrade data into the target device.

[0057] Exemplarily, during the existing program upgrade process, relevant data and program running parameters in the program upgrade data are modified after the upgrade is completed; while the program in the present application does not modify the upgrade data after the upgrade is completed, but only updates the program running parameters. The prior art erases the data to be modified and then fills in the modified data. However, there is a minimum erasure limit for the amount of erased data. In short, if you want to modify 3 data items, assuming the minimum erasure limit is 6, then at this time, 3 additional data items need to be erased. At the same time, such an operation is equivalent to modifying the original upgrade data. When a problem occurs in the program, it is impossible to accurately locate the position where the problem occurred. While for the program in the present application, if a problem occurs, it can be directly compared with the original upgrade data to directly locate the problem. In addition, the solution of the present application can also distinguish the first upgrade of the program according to the above steps and is no longer affected by the old-level data.

[0058] Exemplarily, before erasing the program in the target device, the method may further include:

[0059] Perform a CRC check on the program upgrade data to determine whether the program upgrade data is complete and correct upgrade data.

[0060] If the program upgrade data is complete and correct upgrade data, erase the program in the target device and write all the program upgrade data into the target device.

[0061] If the program upgrade data is not complete and correct upgrade data, perform a CRC check on the program in the target device; if the program in the target device is complete and correct data, execute the original program; if the program in the target device is not complete and correct data, re-obtain the program upgrade data.

[0062] Exemplarily, when writing the program upgrade data into the target device, it is necessary to ensure that the program upgrade data is complete and correct upgrade data, so as to ensure the stable operation of the program in the target device after the upgrade.

[0063] Exemplarily, performing a CRC check on the program upgrade data to determine whether the program upgrade data is complete and correct upgrade data may include:

[0064] Based on a preset generation polynomial, perform an exclusive OR operation on the program upgrade data in binary to obtain a first CRC check value.

[0065] If the CRC check value stored in the check bit of the program upgrade data is the same as the first CRC check value, the program upgrade data is complete and correct upgrade data.

[0066] Exemplarily, the preset generation polynomial may include: CRC-8 generation polynomial, CRC-16 generation polynomial, CRC-32 generation polynomial, CRC-64 generation polynomial, or CRC-CCITT generation polynomial.

[0067] Exemplarily, the polynomial representation of the CRC-8 generation polynomial is: x 8 +x 2 +x 1 +1, and the binary representation is: 100000111. The polynomial representation of the CRC-16 generation polynomial is: x 16 +x 15 +x 2 +1, and the binary representation is: 11000000000000101. The polynomial representation of the CRC-32 generation polynomial is:

[0068] x 32 +x 26 +x 23 +x 22 +x 16 +x 12 +x 11 +x 10 +x 8 +x 7 +x 5 +x 4 +x 2 +x 1 +1, and the binary representation is: 1001100000110111011011011111101. The polynomial representation of the CRC-64 generation polynomial is:

[0069] x 64 +x 4 +x 3 +x 1 +1, and the binary representation is:

[0070] 100000000000000000000000000000000000000000000000000000000000111. The polynomial representation of the CRC-CCITT generation polynomial is: x 16 +x 12 +x 5 +1, and the binary representation is: 10001000000100001.

[0071] Exemplarily, based on the preset generation polynomial, perform an exclusive OR operation on the program upgrade data in binary. Simply put, it is to calculate the remainder of the program upgrade data based on the preset generation polynomial, and the final remainder is the first CRC check value.

[0072] Exemplarily, writing all the program upgrade data into the target device may include:

[0073] Dividing the program upgrade data into multiple consecutive sub - data sets.

[0074] Writing the multiple consecutive sub - data sets in sequence.

[0075] For each sub - data set, after the writing of the sub - data set is completed, obtain the content corresponding to the sub - data set in the target device at this time; if the program corresponding to the sub - data set in the target device at this time is exactly the same as the sub - data set, the data comparison of the sub - data set is correct, if the content corresponding to the sub - data set in the target device at this time is not exactly the same as the sub - data set, the data comparison of the sub - data set is incorrect, re - write the sub - data set, if the number of times of incorrect data comparison of the sub - data set exceeds the preset threshold, re - perform the upgrade.

[0076] If the data comparison of all sub - data sets is correct, the upgrade of the program in the target device is completed.

[0077] Exemplarily, the method may further include:

[0078] After the upgrade of the program in the target device is completed, update the program operation parameters of the target device at this time; wherein, the updated program operation parameters will not cause the target device to perform an upgrade again.

[0079] Exemplarily, after the upgrade is completed, no changes are made to the program upgrade data, only the program operation parameters are updated to ensure the integrity of the upgrade data.

[0080] The above - mentioned power embedded terminal program upgrade method can determine whether the program of the target device needs to be upgraded according to the program upgrade data and program operation parameters of the target device. When the program needs to be upgraded, it can also determine the target upgrade process corresponding to the target device from multiple program upgrade processes according to the program configuration, and upgrade the program in the target device using the program upgrade data according to the target upgrade process. Compared with the traditional BIOS, the BIOS of the present application can be applied to upgrade the programs in various types of power embedded terminals, making the BIOS applicable to more scenarios. When the BIOS is transplanted and used, only the configuration of the BIOS itself and the underlying driver need to be modified, without caring about the issues of the process and logic of the update program. Compared with the traditional BIOS that rewrites the entire set of logic according to different requirements, the workload is greatly reduced.

[0081] It should be understood that the magnitudes of the sequence numbers of the steps in the above - mentioned embodiments do not mean the sequence of execution. The execution sequence of each process should be determined according to its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.

If the number of times the data comparison of the sub-dataset is incorrect exceeds a preset threshold, then re-perform the upgrade.
