Description

[0002] Firmware is generally stored in an erasable programmable read-only memory, an electrically erasable programmable read-only memory or a FLASH chip in a device. Generally speaking, firmware refers to program code (or software) that performs the most basic and bottom-level work of a device and enables the device to run.

[0003] In order to solve some bugs and compatibility problems, or to comprehensively or selectively meet customer needs, more and more manufacturers improve product reliability and user experience through firmware upgrade.

[0004] At present, during firmware upgrade, firmware upgrade files usually need to go through communication transmission, medium caching and the like. However, in the process of communication transmission or medium caching, the content in the firmware upgrade file may be damaged due to transmission, or for different functional chips in an embedded system, the firmware upgrade file originally intended to be transmitted to chip A may be transmitted to chip B, thereby causing the chip to receive an abnormal upgrade file. The abnormal upgrade file is written into the device during firmware upgrade, which may cause the device to have the risk of upgrade damage. SUMMARY

Then, it uses the second verification code to determine if the first verification code was corrupted during transmission. If the first verification code was not corrupted during transmission, it uses the first verification code to determine if the firmware upgrade file was corrupted during transmission. If the firmware upgrade file was also not corrupted during transmission, it uses a unique identifier in the firmware upgrade file to determine if it matches the firmware to be upgraded in the current chip. Finally, if the firmware upgrade file matches the firmware to be upgraded in the current chip, it upgrades the firmware to be upgraded in the current chip according to the firmware upgrade file. On the one hand, layer-by-layer verification ensures that the firmware upgrade file in the received upgrade file package is not damaged or corrupted. On the other hand, after confirming that an undamaged or corrupted firmware upgrade file has been received, the unique identifier in the firmware upgrade file ensures that only the matching firmware upgrade file is used to upgrade the firmware to be upgraded in the current chip, thereby effectively reducing the possibility of damaging the device containing the firmware during the firmware upgrade process. Moreover, this application avoids the uncertainty caused by receiving the upgrade file package once and then making subsequent judgments or upgrades, which is conducive to improving the efficiency of firmware upgrades.

[0063] In the following description, for purposes of explanation and not limitation, specific details are set forth such as particular architectures, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. However, it will be apparent to those skilled in the art that the present application can be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known methods, devices, circuits, and

[0064] In order to make the objects, technical solutions and advantages of the present application clearer, the following will be described in conjunction with the accompanying drawings and specific embodiments.

[0065] Referring to Figure 1 which shows the implementation flowchart of the firmware upgrade method provided by the embodiments of the present application, and will be described in detail as follows:

[0066] In step 101, an upgrade file package is received.

[0067] The upgrade file package can be generated by a sender (such as an upgrade server, etc.) sending the upgrade file package. In the embodiments, the upgrade file package includes not only a firmware upgrade file, but also a check code for checking whether the firmware upgrade file is damaged or abnormal. Similarly, the upgrade server can also generate firmware source code corresponding to the current version of the firmware.

[0068] For different firmwares in an embedded system, such as inverter chip firmware and rectifier chip firmware in an uninterruptible power supply system, the upgrade server can set different identification codes for the different firmwares as unique identification codes of the corresponding firmwares, so as to distinguish the different firmwares.

[0069] For the same firmware, the upgrade server can write the unique identification code corresponding to the firmware in a preset addressable region of the firmware source code when generating the firmware source code. Similarly, the upgrade server can also write the unique identification code corresponding to the firmware in a preset addressable region of the firmware upgrade file when generating the firmware upgrade file.

[0070] The preset addressable region in the firmware source code and the firmware upgrade file is a fixed addressable region for filling the unique identification code of the firmware. When the firmware upgrade file is generated, the unique identification code can be found through addressable search.

[0071] In the embodiments, a fixed addressable region is set in the firmware source code and the firmware upgrade file to fill the unique identification code of the firmware, which is beneficial to distinguishing different firmware upgrade files during firmware upgrade, so as to avoid firmware confusion in the case of more chips in the embedded system.

[0072] In step 102, the firmware upgrade file, the first check code corresponding to the firmware upgrade file, and the second check code corresponding to the first check code are extracted from the upgrade file package.

[0073] As described above, in the embodiment, when the sender generates the upgrade file package, in addition to generating a firmware upgrade file, a check code for checking whether the firmware upgrade file is damaged or abnormal is also generated.

[0074] For example, after the firmware upgrade file is generated, the generated firmware upgrade file is checked by using a check algorithm to generate a check code A corresponding to the firmware upgrade file. On this basis, the generated check code A is checked by using the check algorithm to generate a check code B corresponding to the check code A. The check code A and the check code B can be arranged at the front end of the firmware upgrade file to form the upgrade file package.

[0075] Since the upgrade file package may be damaged or abnormal in the process from the sender sending the upgrade file package to the chip firmware receiving the upgrade file package, after the upgrade file package is received, the firmware upgrade file, the first check code corresponding to the firmware upgrade file, and the second check code corresponding to the first check code can be extracted from the upgrade file package, so as to check whether the received upgrade file package is damaged or abnormal.

[0076] The first check code corresponds to the check code A, and the second check code corresponds to the check code B. Since the upgrade file package may be damaged or abnormal in the transmission process, the received first check code may be the same as or different from the check code A generated by the sender, the received second check code may be the same as or different from the check code B generated by the sender, and on this basis, the received firmware upgrade file may be the same as or different from the firmware upgrade file generated by the sender. Accordingly, whether the received upgrade file package is damaged or abnormal can be checked.

[0077] For example, the check algorithm used by the sender when generating the check code A can be a message digest algorithm (Message Digest Algorithm MD5) or a cyclic redundancy check algorithm (Cyclic Redundancy Check, CRC), such as CRC32. The check algorithm used when generating the check code B can be a CRC or an accumulation sum check algorithm, such as CRC16. According to needs, the check algorithm for generating the check code A and the check algorithm for generating the check code B can be the same or different, which is not limited in the embodiment.

[0078] In step 103, whether the first check code is wrong in the transmission process is judged according to the second check code.

[0079] Optionally, judging whether the first check code is wrong in the transmission process according to the second check code can include:

[0080] According to the first preset check algorithm, the first check code is checked and calculated to obtain a third check code; the first preset check algorithm is the same as the first check algorithm used by the sender of the upgrade file package to calculate the second check code.

[0081] It is judged whether the third check code is the same as the second check code.

[0082] If the third check code is the same as the second check code, it is determined that the first check code is not wrong in the transmission process.

[0083] If the third check code is not the same as the second check code, it is determined that the first check code is wrong in the transmission process.

[0084] In the embodiment, the first preset check algorithm and the first check algorithm are the check algorithm used to generate the check code B in step 102. Since the sender uses the first check algorithm to check and calculate the generated check code A to obtain the check code B (i.e. the second check code), after receiving the first check code corresponding to the check code A, the first check code is also checked and calculated by using the first check algorithm to obtain the third check code. If the third check code is different from the second check code, it indicates that the received first check code has changed relative to the check code A generated by the sender, that is, the first check code is wrong in the transmission process; if the third check code is the same as the second check code, it indicates that the received first check code has not changed relative to the check code A generated by the sender, that is, the first check code is not wrong in the transmission process.

[0085] In step 104, if it is determined that the first check code is not wrong in the transmission process, it is judged according to the first check code whether the firmware upgrade file is wrong in the transmission process.

[0086] Optionally, judging whether the firmware upgrade file is wrong in the transmission process according to the first check code can include:

[0087] According to the second preset check algorithm, the firmware upgrade file is checked and calculated to obtain a fourth check code; the second preset check algorithm is the same as the second check algorithm used by the sender of the upgrade file package to calculate the first check code.

[0088] It is judged whether the fourth check code is the same as the first check code.

[0089] If the fourth check code is the same as the first check code, it is determined that the firmware upgrade file is not wrong in the transmission process.

[0090] If the fourth check code is not the same as the first check code, it is determined that the firmware upgrade file is wrong in the transmission process.

[0091] In the embodiment, the second preset check algorithm and the second check algorithm are the check algorithm used to generate the check code A in step 102. Since the sender uses the second check algorithm to perform check calculation on the generated firmware upgrade file to obtain the check code A (i.e. the first check code), after receiving the firmware upgrade file, the second check algorithm is also used to perform check calculation on the firmware upgrade file to obtain the fourth check code. If the fourth check code is different from the first check code, it indicates that the received firmware upgrade file has changed relative to the firmware upgrade file generated by the sender, i.e. the firmware upgrade file has an error in the transmission process; if the fourth check code is the same as the first check code, it indicates that the received firmware upgrade file has not changed relative to the firmware upgrade file generated by the sender, i.e. the firmware upgrade file has no error in the transmission process.

[0092] In the embodiment, in the case that it is determined that the first check code has no error in the transmission process, the first check code is further used to determine whether the firmware upgrade file has an error in the transmission process, so that the determination result is more accurate.

[0093] In step 105, if it is determined that the firmware upgrade file has no error in the transmission process, the unique identification code in the firmware upgrade file is used to determine whether the firmware upgrade file matches the firmware to be upgraded in the current chip.

[0094] Optionally, the unique identification code in the firmware upgrade file is used to determine whether the firmware upgrade file matches the firmware to be upgraded in the current chip, including:

[0095] determining whether the unique identification code in the firmware upgrade file is the same as the unique identification code in the firmware source code corresponding to the firmware to be upgraded in the current chip;

[0096] If the unique identification code in the firmware upgrade file is the same as the unique identification code in the firmware source code corresponding to the firmware to be upgraded in the current chip, it is determined that the firmware upgrade file matches the firmware to be upgraded in the current chip.

[0097] If the unique identification code in the firmware upgrade file is not the same as the unique identification code in the firmware source code corresponding to the firmware to be upgraded in the current chip, it is determined that the firmware upgrade file does not match the firmware to be upgraded in the current chip.

[0098] In the embodiment, the unique identification code stored in the firmware source code corresponding to the firmware upgrade file and the firmware to be upgraded in the current chip can be determined in advance, and then it is judged whether the unique identification code in the firmware upgrade file is consistent with the unique identification code in the firmware source code corresponding to the firmware to be upgraded in the current chip. When the two are consistent, it means that the firmware upgrade file is the firmware upgrade file corresponding to the firmware to be upgraded in the current chip, that is, it means that the firmware to be upgraded in the current chip can be upgraded by using the firmware upgrade file. If the two are not consistent, it means that the firmware upgrade file does not match the firmware to be upgraded in the current chip, and then upgrading the firmware to be upgraded in the current chip by using the firmware upgrade file may cause the device where the firmware is located to be damaged.

[0099] In step 106, if it is determined that the firmware upgrade file matches the firmware to be upgraded in the current chip, the firmware to be upgraded in the current chip is upgraded according to the firmware upgrade file.

[0100] Optionally, after judging whether the first check code is wrong in the transmission process according to the second check code, it can further include: if it is determined that the first check code is wrong in the transmission process, a prompt information is sent to prompt that the upgrade file package is wrong.

[0101] After judging whether the firmware upgrade file is wrong in the transmission process according to the first check code, it can further include: if it is determined that the firmware upgrade file is wrong in the transmission process, a prompt information is sent to prompt that the upgrade file package is wrong.

[0102] After judging whether the firmware upgrade file matches the firmware to be upgraded in the current chip according to the unique identification code in the firmware upgrade file, it can further include: if it is determined that the firmware upgrade file does not match the firmware to be upgraded in the current chip, a prompt information is sent to prompt that the upgrade file package is wrong.

[0103] In the embodiment, after extracting the firmware upgrade file, the first check code corresponding to the firmware upgrade file, and the second check code corresponding to the first check code from the upgrade file package, only when it is determined that the first check code and the firmware upgrade file are not wrong in the transmission, and the firmware upgrade file matches the firmware to be upgraded in the current chip, the firmware to be upgraded in the current chip is upgraded based on the received firmware upgrade file. If any of the above determinations is wrong, a prompt information is sent to prompt that the upgrade file package is wrong. This is further conducive to minimizing the possibility of damaging the device where the firmware is located during the firmware upgrade process.

[0104] Referring to Figure 2FIG. 2 shows a flow chart of the implementation of the firmware upgrade method provided by another embodiment of the present application. In the firmware upgrade method provided by another embodiment of the present application, the upgrade file package includes: a position mark code of the unique identification code in the firmware upgrade file. The position mark code and the first check code corresponding to the firmware upgrade file constitute a joint check code. The firmware upgrade method is described in detail as follows:

[0105] In step 201, the upgrade file package is received.

[0106] In step 202, the firmware upgrade file, the first check code corresponding to the firmware upgrade file, the position mark code, and the second check code corresponding to the joint check code are extracted from the upgrade file package.

[0107] In step 203, it is judged whether the joint check code is wrong in the transmission process according to the second check code.

[0108] In step 204, if it is judged that the joint check code is not wrong in the transmission process, it is judged whether the firmware upgrade file is wrong in the transmission process according to the first check code in the joint check code.

[0109] In step 205, if it is judged that the firmware upgrade file is not wrong in the transmission process, the position mark code in the joint check code is used to obtain the unique identification code in the firmware upgrade file; and it is judged whether the firmware upgrade file matches the firmware to be upgraded in the current chip according to the obtained unique identification code in the firmware upgrade file.

[0110] In step 206, if it is judged that the firmware upgrade file matches the firmware to be upgraded in the current chip, the firmware to be upgraded in the current chip is upgraded according to the firmware upgrade file.

[0111] Compared with the firmware upgrade method of steps 101 to 106, in this embodiment, when the upgrade file package is generated, not only the check code A corresponding to the firmware upgrade file and the check code B corresponding to the check code A are generated, but also the position mark code is generated, which is used to mark the addressable area in which the unique identification code is stored in the firmware upgrade file, so as to facilitate the subsequent obtaining of the unique identification code in the firmware upgrade file.

[0112] Adaptive, since the upgrade file package in the embodiment includes not only the firmware upgrade file, but also the check code A and the position mark code, in order to avoid the impact of the damage or error of the check code A and the position mark code in the transmission process on the firmware upgrade, a check calculation is performed on the joint check code composed of the check code A and the position mark code to generate a new check code B, so that the firmware upgrade file, the check code A corresponding to the firmware upgrade file, the position mark code, the joint check code composed of the position mark code and the check code A, and the new check code B corresponding to the joint check code are packaged into the upgrade file package and sent out. After receiving the upgrade file package, the receiver extracts the received firmware upgrade file, the received check code A (i.e. the first check code), the received position mark code, and the received new check code B (i.e. the second check code) from the upgrade file package, and then judges whether the received position mark code + the first check code is transmitted incorrectly according to the second check code; when the received position mark code + the first check code is not transmitted incorrectly, it is judged whether the received firmware upgrade file is transmitted incorrectly according to the first check code; when the received firmware upgrade file is not transmitted incorrectly, the unique identification code is accurately extracted from the firmware upgrade file according to the position mark code which is not transmitted incorrectly; finally, when the firmware upgrade file matches the firmware to be upgraded in the current chip according to the accurate unique identification code, the firmware upgrade is performed on the firmware to be upgraded in the current chip according to the firmware upgrade file which is not transmitted incorrectly. Thus, the possibility of damaging the device where the firmware is located in the firmware upgrade process is further reduced.

[0113] Optionally, judging whether the joint check code is transmitted incorrectly according to the second check code can include:

[0114] performing a check calculation on the joint check code according to a third preset check algorithm to obtain a fifth check code; the third preset check algorithm is the same as the third check algorithm used by the sender of the upgrade file package to calculate the second check code;

[0115] judging whether the fifth check code is the same as the second check code;

[0116] if the fifth check code is the same as the second check code, it is determined that the joint check code is not transmitted incorrectly in the transmission process;

[0117] if the fifth check code is not the same as the second check code, it is determined that the joint check code is transmitted incorrectly in the transmission process.

[0118] The embodiment is a specific process of judging whether the joint check code is wrong in the transmission process according to the second check code, which is similar to the specific process of judging whether the first check code is wrong in the transmission process according to the second check code in step 103. However, since the received upgrade file package includes the first check code and the position mark code corresponding to the firmware upgrade file in addition to the firmware upgrade file, the first check code and the position mark code need to be judged whether they are wrong in the transmission process. Therefore, the sender can perform check calculation on the joint check code composed of the check code A and the position mark code to generate a new check code B. Similarly, the receiver can perform check calculation again on the joint check code composed of the received check code A (i.e. the first check code) and the position mark code to obtain a fifth check code, and then judge whether the fifth check code is same as the received new check code B (i.e. the second check code) to judge whether the joint check code composed of the received check code A (i.e. the first check code) and the position mark code is wrong in the transmission process.

[0119] The embodiment of the application extracts the firmware upgrade file, the first check code corresponding to the firmware upgrade file and the second check code corresponding to the first check code from the upgrade file package after receiving the upgrade file package, judges whether the first check code is wrong in the transmission process according to the second check code, judges whether the firmware upgrade file is wrong in the transmission process according to the first check code in the case that the first check code is determined not to be wrong in the transmission process, judges whether the firmware upgrade file matches the firmware to be upgraded in the current chip according to the unique identification code in the firmware upgrade file in the case that the firmware upgrade file is determined not to be wrong in the transmission process, and upgrades the firmware to be upgraded in the current chip according to the firmware upgrade file in the case that the firmware upgrade file matches the firmware to be upgraded in the current chip. On the one hand, the firmware upgrade file in the received upgrade file package can be ensured not to be damaged or wrong through layer-by-layer check, and on the other hand, the unique identification code in the firmware upgrade file can be used to ensure that only the matched firmware upgrade file is used to upgrade the firmware to be upgraded in the current chip after it is determined that the received firmware upgrade file is not damaged or wrong, thereby effectively reducing the possibility that the device where the firmware is located is damaged in the firmware upgrade process. Moreover, the subsequent judgment or upgrade can be performed through once receiving the upgrade file package, thereby avoiding the uncertainty caused by multiple receiving and being beneficial to improving the firmware upgrade efficiency.

[0120] It should be understood that the size of the serial number of each step in the above embodiment does not mean the order of execution, the execution order of each process should be determined according to its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the application.

[0124] The receiving module 31 is used for receiving an upgrading file package;

[0125] The extracting module 32 is used for extracting a firmware upgrading file, a first check code corresponding to the firmware upgrading file and a second check code corresponding to the first check code from the upgrading file package;

[0126] The first processing module 33 is used for judging whether the first check code is wrong in a transmission process according to the second check code;

[0127] The second processing module 34 is used for judging whether the firmware upgrading file is wrong in the transmission process according to the first check code if it is judged that the first check code is not wrong in the transmission process;
