[0031] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Combine the following Figure 1-Figure 5 The firmware upgrade method provided by the present invention is described. The firmware upgrade method provided by the present invention can be applicable to the situation where the BMC firmware upgrade reduces the memory overhead. The execution subject of the method can be an electronic device or a firmware upgrade device set in the electronic device. The configuration device of the control interface can be implemented by software, hardware or a combination of both. Figure 1 It is a flowchart of the firmware upgrade method provided by the present invention, such as Figure 1 As shown, the method includes step 101, step 102, step 103 and step 104.

[0033] Step 101: Obtain firmware program information and firmware image distribution information of the firmware.

[0034] In this step, the firmware image distribution information is used to indicate the image distribution of the firmware. The firmware may not be of different types, for example, it may be a BMC, which is not limited in this embodiment. The firmware program information is the firmware program of the firmware.

[0035] Specifically, firmware program information of the firmware and firmware image distribution information for indicating image distribution of the firmware are obtained.

[0036] Step 102: Group the firmware program information according to the image distribution of the firmware image distribution information to obtain target firmware grouping information.

[0037] In a specific implementation, the firmware program information is grouped according to the mirror distribution of the firmware image distribution information to obtain the target firmware grouping information. The specific implementation method includes: grouping the firmware program information according to the mirror distribution of the firmware image distribution information to obtain firmware program grouping information; encrypting the firmware program grouping information to obtain firmware grouping encryption information; determining the target firmware grouping information based on the firmware grouping encryption information, a hash algorithm and an encryption algorithm.

[0038] Specifically, the firmware program information is grouped according to the image distribution of the firmware image distribution information to obtain firmware program grouping information; the firmware program grouping information is encrypted by an Advanced Encryption Standard (AES) encryption engine to obtain firmware grouping encrypted information; and the target firmware grouping information is determined according to the firmware grouping encrypted information, a hash algorithm, and an encryption algorithm.

[0039] In a specific implementation, the specific implementation of determining the target firmware group information based on the firmware group encryption information, the hash algorithm and the encryption algorithm includes: performing a hash calculation based on the firmware group encryption information and the hash algorithm to obtain firmware summary data; signing the firmware summary data based on the encryption algorithm to obtain a signature byte; appending the signature byte to the firmware group encryption information to obtain the target firmware group information.

[0040] In this step, the encryption algorithm may be, for example, a cryptographic system (Rivest-Shamir-Adleman, RSA), which is not limited in this embodiment. RSA is an asymmetric encryption algorithm with two different keys, one is a public key and the other is a private key.

[0041] Specifically, a hash calculation is performed according to the firmware group encryption information and a hash algorithm to obtain firmware summary data; the firmware summary data is signed according to the encryption algorithm to obtain a signature byte; and the signature byte is appended to the firmware group encryption information to obtain the target firmware group information.

[0042] Exemplarily, taking BMC firmware as an example, the firmware program information is grouped according to the image distribution of the firmware image distribution information to obtain firmware program grouping information. For example, for BMC, the firmware program information corresponding to the BMC is grouped according to the corresponding firmware image distribution information to obtain firmware program grouping information, such as uboot.bin, kernel.bin, rofs.bin and rwfs.bin, and then encrypted by the RSA encryption engine to obtain encrypted firmware group encryption information, such as uboot-enc.bin, kernel-enc.bin, rofs-enc.bin and rwfs-enc.bin, and further encrypted by the hash algorithm. The firmware group encrypted information is hashed to obtain firmware summary data, and the firmware summary data is further signed by an encryption algorithm to obtain a signature byte; after the signature byte is appended to the firmware group encrypted information, the target firmware group information is obtained, for example, Bmc-Firmware.bin, and Bmc-Firmware.bin includes uboot-enc.bin, signature.bin, kernel-enc.bin, signature.bin, rofs-enc.bin, signature.bin and rwfs-enc.bin, signature.bin, which is not limited in this embodiment.

[0043] The advantage of this setting is that after grouping, subsequent transmission and upgrade can reduce memory consumption.

[0044] Step 103: Determine the firmware upgrade package information according to the target firmware grouping information and the basic attribute information of the firmware.

[0045] In this step, the basic attribute information refers to information describing the properties of the firmware, and the basic attribute information includes the firmware model, firmware version, firmware starting position, firmware size, and the number of firmware groups, which is not limited in this embodiment.

[0046] Specifically, after the firmware program group information is encrypted, the firmware programs corresponding to all the encrypted target firmware group information are merged into an upgrade package, and the basic attribute information of the firmware is filled in to obtain the merged upgrade information, and then the firmware upgrade package information is determined based on the merged upgrade information analysis.

[0047] Exemplarily, after obtaining the target firmware grouping information of the firmware, for various types of firmware, target firmware grouping information of various types of firmware is obtained. Various types of firmware may be, for example, Bmc, Psu, Bios, and Cpld, etc., which is not limited in this embodiment. Then, the target firmware grouping information of Bmc, Psu, Bios, and Cpld, etc. may be obtained, such as Bmc-Firmware.bin, Psu-Firmware.bin, Bios-Firmware.bin, and Cpld-Firmware.bin, and the data header is further filled with the basic attribute information of the firmware to obtain the merged upgrade information, such as Update-Firmware.bin, which includes Header.bin, Bmc-Firmware.bin, Psu-Firmware.bin, Bios-Firmware.bin, and Cpld-Firmware.bin. in and Cpld-Firmware.bin, wherein Header.bin represents basic attribute information, and Header.bin includes basic information of different types of firmware, such as Bmc-Header, Psu-Header, Bios-Header, and Cpld-Header, and each basic information includes the firmware model, firmware version, firmware starting position, firmware size, and number of firmware groups of the firmware. Taking BMC as an example, Bmc-Header includes BMC firmware model, BMC firmware version, BMC firmware starting position, BMC firmware size, and number of BMC firmware groups, which are not limited in this embodiment.

[0048] The advantage of this setting is that it provides concurrent processing of multiple firmware services, reduces the problem of memory resource shortage caused by the upgrade process, and reduces memory overhead.

[0049] In a specific embodiment, a specific implementation method of determining firmware upgrade package information based on target firmware grouping information and basic attribute information of the firmware includes: parsing the target firmware grouping information to determine whether all firmware components in the target firmware grouping information have been upgraded; when all firmware components have been upgraded, parsing to obtain firmware upgrade package information; when all firmware components have not been upgraded, determining whether an upgrade is required based on the firmware version; when it is determined that an upgrade is not required, continuing to return to execute the step of determining whether all firmware components in the target firmware grouping information have been upgraded; when it is determined that an upgrade is required, determining whether all firmware packages have been upgraded based on the firmware model, the firmware starting position, the firmware size, and the number of firmware groups; when it is determined that all firmware packages have been upgraded, continuing to return to execute the step of determining whether all firmware components in the target firmware grouping information have been upgraded; when it is determined that all firmware packages have not been upgraded, continuing to return to execute the step of determining whether all firmware packages have been upgraded based on the firmware model, the firmware starting position, the firmware size, and the number of firmware groups.

[0050] Specifically, Figure 2 Schematic diagram of determining the firmware upgrade package information provided by the present invention. Figure 2 As shown, the firmware upgrade package information determination includes the following steps.

[0051] Step 201: parse target firmware grouping information.

[0052] Specifically, the number of upgrade components in the target firmware grouping information is parsed.

[0053] Step 202: Determine whether all firmware components in the target firmware grouping information have been upgraded.

[0054] Specifically, determine whether all firmware components have been upgraded according to the number of upgraded components after parsing. If it is determined that all firmware components in the target firmware grouping information have not been upgraded, continue to execute step 203; if it is determined that all firmware components in the target firmware grouping information have been upgraded, continue to execute step 206; Step 203: Determine whether an upgrade is required based on the firmware version.

[0055] Specifically, it is determined whether an upgrade is required according to the firmware version. If it is determined that an upgrade is not required, the process returns to step 202 ; if it is determined that an upgrade is required, the process continues to step 204 .

[0056] Step 204: Obtain the firmware model, firmware starting position, firmware size, and firmware group quantity.

[0057] Specifically, when it is determined that an upgrade is required, the firmware model, the firmware starting position, the firmware size, and the number of firmware groups are obtained.

[0058] Step 205: Determine whether the upgrade is complete.

[0059] Specifically, when it is determined that an upgrade is required, determine whether all firmware packages have been upgraded based on the firmware model, firmware starting position, firmware size and number of firmware groups; when it is determined that all firmware packages have been upgraded, continue to return to execute step 202; when it is determined that all firmware packages have not been upgraded, continue to return to execute step 204.

[0060] Step 206: parse and obtain the firmware upgrade package information.

[0061] Specifically, when all firmware components are upgraded, the firmware upgrade package information is parsed and obtained.

[0062] The advantage of this setting is that after obtaining the firmware model, firmware starting position, firmware size and number of firmware groups, the firmware packages of specific individual components are upgraded one by one. During the upgrade, according to the grouping information of the firmware package of the individual component, the small firmware package data of the individual component groupings are uploaded one by one until the small firmware package data is upgraded. Then, the remaining small firmware packages are uploaded until all firmware packages are upgraded, thereby ensuring that all firmware packages are upgraded and reducing the memory occupied by the upgrade.

[0063] Step 104: Determine the firmware upgrade result of the firmware according to the firmware upgrade package information.

[0064] In a specific embodiment, a specific implementation method of determining a firmware upgrade result of a firmware according to firmware upgrade package information includes: applying for a first target byte cache, parsing the firmware upgrade package information using an encryption algorithm, obtaining a signature parsing result, and storing the signature parsing result in the first target byte cache; applying for a second target byte cache, parsing the firmware upgrade package information using a hash algorithm, obtaining a firmware hash value, and storing the firmware hash value in the second target byte cache; determining whether the signature parsing result in the first target byte cache is consistent with the firmware hash value in the second target byte cache; when the signature parsing result is consistent with the firmware hash value, releasing the first target byte cache and the second target byte cache, applying for a third target byte cache, and determining whether the firmware upgrade package information is decrypted; when the firmware upgrade package information is decrypted, releasing the third target byte cache, and starting the upgrade process according to the upgrade algorithm to obtain the firmware upgrade result.

[0065] Specifically, Figure 3 Schematic diagram of determining the firmware upgrade result provided by the present invention. Figure 3 As shown, the firmware upgrade result determination includes the following steps.

[0066] Step 301: Apply for a first target byte cache, parse the firmware upgrade package information using an encryption algorithm, obtain a signature parsing result, and store the signature parsing result in the first target byte cache.

[0067] In this step, the first target byte cache may be, for example, a 256-byte cache, and the encryption algorithm may be, for example, an RSA asymmetric encryption algorithm, which is not limited in this embodiment.

[0068] Specifically, apply for the first target byte cache, use the RSA asymmetric encryption algorithm to parse the firmware upgrade package information, obtain the signature parsing result, and store the signature parsing result in the first target byte cache.

[0069] Step 302: Apply for a second target byte cache, parse the firmware upgrade package information using a hash algorithm, obtain a firmware hash value, and store the firmware hash value in the second target byte cache.

[0070] In this step, the second target byte cache may be, for example, a 256-byte cache, which is not limited in this embodiment.

[0071] Specifically, apply for a second target byte cache, use a hash algorithm to parse the firmware upgrade package information, obtain a firmware hash value, and store the firmware hash value in the second target byte cache.

[0072] Step 303: Determine whether the signature parsing result in the first target byte cache is consistent with the firmware hash value in the second target byte cache.

[0073] Specifically, determine whether the signature parsing result in the first target byte cache is consistent with the firmware hash value in the second target byte cache. If the signature parsing result is consistent with the firmware hash value, continue to execute step 305; if the signature parsing result is inconsistent with the firmware hash value, continue to execute step 304.

[0074] Step 304: Issue a verification exception message.

[0075] In this step, the verification exception information is used to indicate that the firmware upgrade has failed.

[0076] Specifically, when the signature parsing result is inconsistent with the firmware hash value, a verification exception message is issued to indicate that the firmware upgrade has failed.

[0077] Step 305: Release the first target byte cache and the second target byte cache.

[0078] Specifically, when the signature parsing result is consistent with the firmware hash value, the first target byte cache and the second target byte cache are released, and step 306 is continued.

[0079] Step 306: Apply for a third target byte cache.

[0080] In this step, the third target byte cache may be, for example, a 32-byte cache, which is not limited in this embodiment.

[0081] Step 307: Determine whether the firmware upgrade package information has been decrypted.

[0082] Specifically, after applying for the third target byte cache, determine whether the firmware upgrade package information is decrypted. If it is determined that the firmware upgrade package information is decrypted, continue to execute step 309; if it is determined that the firmware upgrade package information is not decrypted, continue to execute step 308.

[0083] Step 308: Obtain cached data and decrypt the cached data.

[0084] Specifically, when it is determined that the firmware upgrade package information has not been decrypted, the cache data of the third target byte is obtained to the third target byte cache, and the cache data of the third target byte is decrypted to encrypt the firmware upgrade package information, and the encrypted firmware upgrade package information is added to the third target byte cache, and then the decrypted cache data is written to the storage location of the data before decryption, and then the execution of step 307 is continued.

[0085] The advantage of this setting is that there is no need to increase additional memory overhead, and after confirming that the firmware upgrade package information decryption is completed, the subsequent upgrade process can be carried out.

[0086] Step 309: Release the third target byte cache.

[0087] Specifically, when the firmware upgrade package information is decrypted, the third target byte cache is released, and step 310 is continued.

[0088] Step 310: Start the upgrade process according to the upgrade algorithm and obtain the firmware upgrade result.
