[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0032] The following is combined Figures 1-5 The firmware upgrade method provided by this invention is described below. This firmware upgrade method is applicable to situations where BMC firmware upgrades reduce memory overhead. The execution subject of this method can be an electronic device or a firmware upgrade device installed in the electronic device. The configuration device of the control interface can be implemented by software, hardware, or a combination of both. Figure 1 This is a flowchart illustrating the firmware upgrade method provided by the present invention, as shown below. Figure 1 As shown, the method includes steps 101, 102, 103 and 104.

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

[0034] In this step, the firmware image distribution information is used to represent the image distribution of the firmware. The firmware does not have to be of a different type; for example, it can be BMC firmware. This embodiment does not limit this. The firmware program information is the firmware program of the firmware.

[0035] Specifically, it obtains firmware program information and firmware image distribution information used to represent the image distribution of the firmware.

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

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

[0039] In a specific embodiment, the specific embodiment of determining the target firmware grouping information according to the firmware grouping encryption information, the hash algorithm, and the encryption algorithm includes: performing hash calculation according to the firmware grouping encryption information and the hash algorithm to obtain firmware digest data; performing signature on the firmware digest data according to the encryption algorithm to obtain a signature segment; and appending the signature segment to the firmware grouping encryption information to obtain the target firmware grouping information.

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

[0041] Specifically, the firmware program grouping information is encrypted by an Advanced Encryption Standard (AES) encryption engine to obtain firmware grouping encryption information; and the target firmware grouping information is determined according to the firmware grouping encryption information, a hash algorithm, and an encryption algorithm.

[0042] For 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, the firmware program grouping information of the Bmc can be uboot.bin, kernel.bin, rofs.bin and rwfs.bin, and then the firmware program grouping information is encrypted by the RSA encryption engine to obtain encrypted firmware grouping information, for example, the encrypted firmware grouping information can be uboot-enc.bin, kernel-enc.bin, rofs-enc.bin and rwfs-enc.bin, the firmware grouping encrypted information is further calculated by the hash algorithm to obtain firmware digest data, and the firmware digest data is further signed by the encryption algorithm to obtain the signature bytes; the signature bytes are appended to the firmware grouping encrypted information to obtain the target firmware grouping information, for example, the target firmware grouping information can be Bmc-Firmware.bin, and the 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, and the embodiment is not limited in this regard.

[0043] The advantage of such a setting is that after grouping, the subsequent transmission and upgrading can reduce the memory consumption.

[0044] Step 103, determining 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 the information describing the nature of the firmware, and the basic attribute information includes the firmware model, the firmware version, the firmware starting position, the firmware size and the firmware grouping number, and the embodiment is not limited in this regard.

[0046] Specifically, after the grouping and encryption of the firmware program grouping information is completed, all the grouped and encrypted target firmware grouping information corresponding to the firmware program is 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.

[0047] For example, after obtaining the target firmware grouping information of the firmware, the target firmware grouping information of different types of firmware is obtained. The different types of firmware can be Bmc, Psu, Bios, and Cpld, etc., which are not limited in the embodiment. Then, the target firmware grouping information of Bmc, Psu, Bios, and Cpld, etc. can be Bmc-Firmware.bin, Psu-Firmware.bin, Bios-Firmware.bin, and Cpld-Firmware.bin, etc. Further, the basic attribute information of the firmware is used to fill the data header to obtain the merging upgrade information, which can be Update-Firmware.bin. The Update-Firmware.bin includes Header.bin, Bmc-Firmware.bin, Psu-Firmware.bin, Bios-Firmware.bin, and Cpld-Firmware.bin. The Header.bin represents the basic attribute information, and the Header.bin includes the basic information of different types of firmware, which can be Bmc-Header, Psu-Header, Bios-Header, and Cpld-Header. Each basic information includes the firmware type, firmware version, firmware starting position, firmware size, and firmware grouping number, etc. Taking the Bmc as an example, the Bmc-Header includes the BMC firmware type, BMC firmware version, BMC firmware starting position, BMC firmware size, and BMC firmware grouping number, etc., which are not limited in the embodiment.

[0048] The advantage of the above setting is that the firmware multi-service concurrent processing is provided, the memory resource shortage problem caused by the upgrade process is reduced, and the memory overhead is reduced.

[0049] In a specific embodiment, the specific implementation of determining the firmware upgrade package information according to the target firmware grouping information and the basic attribute information of the firmware includes: parsing the target firmware grouping information, determining whether all firmware components in the target firmware grouping information are upgraded; in the case that all firmware components are upgraded, obtaining the firmware upgrade package information; in the case that all firmware components are not upgraded, determining whether upgrading is needed according to the firmware version; in the case that it is determined that upgrading is not needed, returning to execute the step of determining whether all firmware components in the target firmware grouping information are upgraded; in the case that it is determined that upgrading is needed, determining whether all firmware packages are upgraded according to the firmware model, the firmware starting position, the firmware size and the firmware grouping quantity; in the case that it is determined that all firmware packages are upgraded, returning to execute the step of determining whether all firmware components in the target firmware grouping information are upgraded; in the case that it is determined that all firmware packages are not upgraded, returning to execute the step of determining whether all firmware packages are upgraded according to the firmware model, the firmware starting position, the firmware size and the firmware grouping quantity.

[0050] Specifically, Figure 2 is a schematic diagram of the firmware upgrade package information provided by the application, as shown in Figure 2 The determination of the firmware upgrade package information includes the following steps.

[0051] Step 201, parsing the target firmware grouping information.

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

[0053] Step 202, determining whether all firmware components in the target firmware grouping information are upgraded.

[0054] Specifically, whether all firmware components are upgraded is determined according to the number of upgraded components after parsing, in the case that it is determined that all firmware components in the target firmware grouping information are not upgraded, step 203 is executed; in the case that it is determined that all firmware components in the target firmware grouping information are upgraded, step 206 is executed.

[0055] Step 203, determining whether upgrading is needed according to the firmware version.

[0056] Specifically, whether upgrading is needed is determined according to the firmware version, in the case that it is determined that upgrading is not needed, step 202 is executed; in the case that it is determined that upgrading is needed, step 204 is executed.

[0057] Step 204, obtaining the firmware model, the firmware starting position, the firmware size and the firmware grouping quantity.

[0058] Specifically, in the case that it is determined that upgrading is needed, the firmware model, the firmware starting position, the firmware size and the firmware grouping quantity are obtained.

[0059] Step 205, determine whether the upgrade is completed.

[0060] Specifically, in the case of determining that the upgrade is needed, it is determined whether all firmware packages are upgraded according to the firmware model, the firmware starting position, the firmware size and the firmware grouping number; in the case of determining that all firmware packages are upgraded, it is continued to return to execute step 202; in the case of determining that all firmware packages are not upgraded, it is continued to return to execute step 204.

[0061] Step 206, parse the firmware upgrade package information.

[0062] Specifically, in the case of determining that all firmware components are upgraded, the firmware upgrade package information is parsed.

[0063] The advantage of such setting is that after obtaining the firmware model, the firmware starting position, the firmware size and the firmware grouping number, the firmware package of a specific single component is started to be upgraded one by one, and when upgrading, the small firmware package data of each component grouping is uploaded one by one according to the grouping information of the firmware package of the single component, until the small firmware package data is upgraded, the uploading of the remaining small firmware package is performed, until all firmware packages are upgraded, which guarantees that all firmware packages are upgraded and reduces the memory occupied by the upgrade.

[0064] Step 104, determine the firmware upgrade result of the firmware according to the firmware upgrade package information.

[0065] In a specific embodiment, the specific embodiment of determining the firmware upgrade result of the firmware according to the firmware upgrade package information comprises: applying a first target byte cache, parsing the firmware upgrade package information by using an encryption algorithm to obtain a signature analysis result, and storing the signature analysis result in the first target byte cache; applying a second target byte cache, parsing the firmware upgrade package information by using a hash algorithm to obtain a firmware hash value, and storing the firmware hash value in the second target byte cache; determining whether the signature analysis result in the first target byte cache is consistent with the firmware hash value in the second target byte cache; in the case of consistency between the signature analysis result and the firmware hash value, releasing the first target byte cache and the second target byte cache, applying a third target byte cache, and determining whether the firmware upgrade package information is decrypted; in the case of completing the decryption of the firmware upgrade package information, releasing the third target byte cache, and starting the upgrade process according to an upgrade algorithm to obtain the firmware upgrade result.

[0066] Specifically, Figure 3 is a schematic diagram of the firmware upgrade result determination provided by the present application, as shown in Figure 3 The firmware upgrade result determination comprises the following steps.

[0067] Step 301, a first target byte cache is applied, a signature analysis result is obtained by using an encryption algorithm to analyze the firmware upgrade package information, and the signature analysis result is stored in the first target byte cache.

[0068] 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 the embodiment.

[0069] Specifically, a first target byte cache is applied, a signature analysis result is obtained by using an RSA asymmetric encryption algorithm to analyze the firmware upgrade package information, and the signature analysis result is stored in the first target byte cache.

[0070] Step 302, a second target byte cache is applied, a firmware hash value is obtained by using a hash algorithm to analyze the firmware upgrade package information, and the firmware hash value is stored in the second target byte cache.

[0071] In this step, the second target byte cache may be, for example, a 256-byte cache, which is not limited in the embodiment.

[0072] Specifically, a second target byte cache is applied, a firmware hash value is obtained by using a hash algorithm to analyze the firmware upgrade package information, and the firmware hash value is stored in the second target byte cache.

[0073] Step 303, it is determined whether the signature analysis result in the first target byte cache is consistent with the firmware hash value in the second target byte cache.

[0074] Specifically, it is determined whether the signature analysis result in the first target byte cache is consistent with the firmware hash value in the second target byte cache, in the case that the signature analysis result is consistent with the firmware hash value, step 305 is executed; in the case that the signature analysis result is not consistent with the firmware hash value, step 304 is executed.

[0075] Step 304, verification exception information is sent out.

[0076] In this step, the verification exception information is used to indicate that the firmware upgrade fails.

[0077] Specifically, in the case that the signature analysis result is not consistent with the firmware hash value, the verification exception information is sent out to indicate that the firmware upgrade fails.

[0078] Step 305, the first target byte cache and the second target byte cache are released.

[0079] Specifically, in the case that the signature analysis 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 executed.

[0080] Step 306, apply the third target byte cache.

[0081] In this step, the third target byte cache may be a 32-byte cache, for example, and the present embodiment does not limit this.

[0082] Step 307, determine whether the firmware upgrade package information is decrypted.

[0083] Specifically, after the third target byte cache is applied, it is determined whether the firmware upgrade package information is decrypted. If it is determined that the firmware upgrade package information is decrypted, step 309 is performed. If it is determined that the firmware upgrade package information is not decrypted, step 308 is performed.

[0084] Step 308, obtain cache data and decrypt the cache data.

[0085] Specifically, if it is determined that the firmware upgrade package information is not 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 for the encrypted firmware upgrade package information. 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 step 307 is returned to continue to be performed.

[0086] The advantage of this setting is that no additional memory overhead is required, and after the firmware upgrade package information is decrypted, the subsequent upgrade process can be performed.

[0087] Step 309, release the third target byte cache.

[0088] Specifically, if the firmware upgrade package information is decrypted, the third target byte cache is released, and step 310 is performed.

[0089] Step 310, start the upgrade process according to the upgrade algorithm to obtain the firmware upgrade result.
