[0024] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without any creative work fall within the protection scope of the present application.

[0025] It should be noted that, in the description of the present application, the terms “comprise”, “contain” or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or device. The terms “first”, “second” and the like in the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence.

[0026] The logic controller can be a complex programmable logic device (CPLD) programmed and configured with logic functions by a hardware description language to perform preset functions in a device such as a server. The logic controller includes a user flash memory and a configuration flash memory. The flash memory information of the user flash memory includes at least an identifier (such as a hardware model or a serial number) of the logic controller, which is used for verification in an upgrade process. The flash memory information of the configuration flash memory includes control logic of a device (such as a power supply, a fan, or an indicator light). The upgrade process of the logic controller is to write an upgrade package received from a remote device into the user flash memory and / or the configuration flash memory.

[0027] In the upgrade process of the logic controller, an upgrade failure can occur due to electromagnetic interference or the like. The configuration flash memory upgrade failure is a recoverable fault, and the upgrade repair can be directly performed through communication. The user flash memory upgrade failure is an unrecoverable fault, and the upgrade repair cannot be directly performed through communication.

[0028] Specifically, the upgrade process of the flash memory is to verify the identifier in the flash memory information and the identifier in the upgrade package, erase the original flash memory information of the flash memory after verification, and rewrite the information in the upgrade package. When the user flash memory upgrade fails, the original flash memory information of the flash memory has been erased, and subsequent verification and upgrade retry processing cannot be performed. When the configuration flash memory upgrade fails, the identifier in the flash memory information of the user flash memory is not erased, and verification can be performed, so that upgrade retry processing can be performed.

[0029] In related technologies, the verification function of the user flash memory is restored by manually operating a burner to rewrite the flash memory information and write the identifier after the logic controller is disassembled. However, disassembly and operation of the burner have a risk of physical damage, such as the logic controller not being provided with a joint test action group physical pin, manual soldering of a historical interface, and a risk of pad damage and electrostatic breakdown, which can cause a problem of low reliability of upgrade management.

[0030] In order for those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] In combination with the specific application environment architecture on which the execution of the flash memory upgrade method depends, the specific application environment architecture is described herein. Refer to Figure 1 , Figure 1As shown in FIG. 1, a schematic diagram of an application scenario of an upgrading method for a flash memory is shown. A flash memory information A is stored in a flash memory of a logic controller in an initial state. The upgrading is triggered by an upgrading package. If the upgrading is successful, the flash memory information A of the logic controller is updated to a flash memory information B. If the upgrading fails, the upgrading retry can be performed. If the upgrading retry is successful, the flash memory information A of the logic controller is updated to the flash memory information B.

[0032] Exemplarily, the application can retain the identification even if the upgrading fails by storing the identification in a position other than the flash memory, so as to verify the upgrading retry according to the identification. Compared with the manner in the related art, the application does not need to be physically disassembled in the upgrading retry process, so as to reduce the risk of the upgrading retry and improve the reliability of the upgrading management.

[0033] Figure 2 As shown in FIG. 2, a schematic diagram of a structure of a logic controller provided by an embodiment of the application is shown. The embodiment of the application provides a logic controller, which comprises a user flash memory, a bus upgrading controller, a flash memory upgrading controller, a retry controller and a flash memory information storage. Figure 2

[0034] The bus upgrading controller is connected with a management controller outside the logic controller through an integrated circuit bus. The bus upgrading controller is connected with the flash memory upgrading controller. The bus upgrading controller is configured to receive an upgrading instruction sent by the management controller and send the upgrading instruction to the flash memory upgrading controller.

[0035] The flash memory upgrading controller is connected with the user flash memory and the retry controller. The flash memory upgrading controller is configured to perform upgrading processing on the user flash memory according to the upgrading instruction and determine an upgrading result.

[0036] The retry controller is connected with the flash memory information storage and the bus upgrading controller. The retry controller is configured to send the flash memory information stored in the flash memory information storage to the bus upgrading controller if the upgrading result is the upgrading failure, so as to instruct the flash memory upgrading controller to perform the upgrading retry processing on the user flash memory.

[0037] The flash memory information storage is connected with the management controller. The flash memory information storage is configured to store the flash memory information according to the upgrading instruction.

[0038] Exemplarily, the management controller can be a baseboard management controller (BMC). The management controller sends the upgrading instruction to trigger the logic controller to perform the upgrading. The upgrading instruction can comprise an upgrading package, so as to make the logic controller perform the upgrading processing according to the upgrading package.

[0039] ​Optionally, the bus upgrade controller is connected to the integrated circuit bus and the bus upgrade controller corresponds to an integrated circuit bus address, so that the management controller accurately sends the upgrade instruction according to the address. The bus upgrade controller obtains the upgrade instruction from the integrated circuit bus according to the address, and the bus upgrade controller can analyze and process the upgrade instruction to obtain the upgrade package in the upgrade instruction.

[0040] For example, the flash memory upgrade controller is used to perform erasing and data writing of the flash memory to realize the upgrade of the flash memory. Specifically, the flash memory upgrade controller drives the user flash memory to perform erasing and data writing operation according to the data in the upgrade instruction.

[0041] For example, in the case of user flash memory upgrade failure, the identification in the flash memory information is verified, thereby reducing the disassembly operation.

[0042] For example, the flash memory information storage stores the flash memory information of the user flash memory before the initial upgrade processing in response to the upgrade instruction, so that the flash memory information is saved as a backup in the flash memory information storage. During the initial upgrade processing, the flash memory information in the flash memory information storage no longer changes, thereby ensuring that the flash memory information in the user flash memory is backed up before being erased, and the backed up flash memory information can be effectively stored, thereby improving the reliability of the upgrade management.

[0043] For example, the flash memory upgrade controller sends a FAIL_FLAG signal to the retry controller through the connection between the flash memory upgrade controller and the retry controller to trigger the upgrade retry.

[0044] For example, the flash memory information is stored in the flash memory information storage, which can be completed by hardware logic throughout the upgrade retry processing, thereby avoiding the disassembly operation.

[0045] The logic controller provided by the embodiment of the present application stores the flash memory information of the user flash memory of the logic controller in the flash memory information storage, so that the upgrade retry can be performed through the flash memory information without the need of physically disassembling and rewriting the flash memory information, thereby avoiding the failure caused by disassembly and improving the reliability of the upgrade management.

[0046] A feasible implementation manner is provided, Figure 3 The structure diagram of the state register provided by the embodiment of the present application is shown in Figure 3 As shown in the figure, the logic controller further includes a state register; the pin of the state register is connected to the flash memory upgrade controller and the user flash memory, and the state register is used to send the upgrade result to the flash memory upgrade controller when the upgrade fails.

[0047] For example, the pin of the state register can read the upgrade state of the user flash memory, and the upgrade result can be determined according to the upgrade state.

[0048] Optionally, the upgrade state read by the status register can be a native electrical signal of the user flash memory, such as a high voltage pulse or a check level.

[0049] Optionally, the flash upgrade controller reads the level signal of the pin of the status register, and determines the upgrade result according to the level signal.

[0050] In this feasible implementation manner, the user flash memory can be monitored in real time by setting the status register, so as to determine the upgrade result, and the flash upgrade controller can perform upgrade retry in time according to the upgrade result.

[0051] A feasible implementation manner, Figure 4 The structure schematic diagram of the logic controller provided by the embodiment of the present application is shown in Figure 4 As shown in the figure, the logic controller further comprises a check controller and a check value storage; the check controller is connected with the retry controller, the output end of the check value storage, and the bus upgrade controller, and is used for performing check processing on the flash information according to the information check value to obtain a first check result, and sending the flash information to the bus upgrade controller according to the first check result; the input end of the check value storage is connected with the bus upgrade controller, and the check value storage is used for generating the information check value corresponding to the user flash memory according to the upgrade instruction, and storing the information check value.

[0052] For example, after the retry controller sends the flash information to the check controller, the check controller performs check processing on the flash information to obtain a first check result, and then sends the flash information to the bus upgrade controller according to the first check result.

[0053] For example, if the first check result is a check pass, the check controller sends the flash information to the bus upgrade controller.

[0054] For example, the basis of the check processing is the information check value stored in the check value storage, and the flash information is checked according to the information check value.

[0055] For example, the first check result is a check pass, which indicates that the flash information is correct information, and then the flash information can be used for upgrade retry.

[0056] In this feasible implementation manner, the upgrade retry is performed according to the accurate flash information through check processing, so as to improve the reliability of the upgrade retry.

[0057] A feasible implementation manner, Figure 5 The structure schematic diagram of the logic controller provided by the embodiment of the present application is shown in Figure 5As shown, the logic controller further comprises a configuration flash memory; the flash memory upgrade controller is connected with the configuration flash memory, and is configured to perform upgrade retry processing on the configuration flash memory according to the upgrade instruction.

[0058] In an example, the upgrade retry of the configuration flash memory is triggered by the bus upgrade controller.

[0059] In an example, the configuration flash memory does not store the identifier, and even if the configuration flash memory is erased in the upgrade process performed by the flash memory upgrade controller, the upgrade retry can be performed by using the identifier in the user flash memory.

[0060] In an example, the channel connected between the flash memory upgrade controller and the configuration flash memory and the channel connected between the flash memory upgrade controller and the user flash memory are independent of each other, so as to avoid conflicts between the upgrade of the configuration flash memory and the upgrade of the user flash memory, and when the upgrade of one of the configuration flash memory and the user flash memory fails, the upgrade retry can be performed only on the flash memory whose upgrade fails.

[0061] In this feasible implementation manner, the channels of the configuration flash memory and the user flash memory are isolated, so as to avoid conflicts between the upgrade of the configuration flash memory and the upgrade of the user flash memory, thereby improving the reliability of the upgrade management.

[0062] Figure 6 A flowchart of the flash memory upgrade method provided by the embodiment of the application is shown in FIG. 1. Figure 6 As shown, the embodiment of the application provides a flash memory upgrade method, and the method is described in detail as follows.

[0063] S601, receiving an upgrade instruction sent by a management controller outside a logic controller.

[0064] In an example, the management controller and the logic controller are connected through an integrated circuit bus, the management controller generates an upgrade instruction according to an upgrade package, and sends the upgrade instruction to the logic controller, so as to instruct the logic controller to perform the upgrade according to the upgrade package in the upgrade instruction.

[0065] S602, performing upgrade processing on a user flash memory according to the upgrade instruction, and determining an upgrade result.

[0066] In an example, the upgrade result is a result obtained after the logic controller performs the upgrade processing on the user flash memory. The upgrade result includes upgrade success or upgrade failure.

[0067] In an example, the upgrade success indicates that the data of the upgrade package has been written into the user flash memory. The upgrade failure indicates that an interruption occurs between the completion of the upgrade processing, so that the data of the upgrade package is not written into the user flash memory.

[0068] With the scene example, if the upgrade is successful, the logic controller can run according to the new data. If the upgrade fails, the logic controller lacks the necessary data to run normally and cannot run normally. In order to restore the normal operation of the logic controller, the upgrade retry method is used for processing.

[0069] S603, if the upgrade result is upgrade failure, the flash information stored in the flash information storage is sent to the bus upgrade controller through the retry controller, so that the bus upgrade controller instructs the flash upgrade controller to perform upgrade retry processing on the user flash.

[0070] For example, when the upgrade result is upgrade failure, the flash upgrade controller has erased the user flash, and the flash information storage can normally store the flash information. The flash information can be read from the flash information storage, and the flash information includes an identifier used for verification during the upgrade process, so that the upgrade retry processing can effectively perform verification.

[0071] Optionally, the bus upgrade controller receives a new upgrade package from the management controller through the integrated circuit bus, or the bus upgrade controller triggers the flash upgrade controller to perform upgrade using the upgrade package in the first upgrade instruction.

[0072] The flash upgrade method provided by the embodiment of the application stores the flash information of the user flash of the logic controller in the flash information storage, so that the upgrade retry can be performed through the flash information, without the need of physically disassembling the device to rewrite the flash information, thereby avoiding the fault caused by disassembly, and improving the reliability of the upgrade management.

[0073] On the basis of any one of the above embodiments, the following will be described in combination with Figure 7 The detailed process of the flash upgrade method will be described.

[0074] Figure 7 A flowchart of a flash upgrade method provided by the embodiment of the application. As shown in the figure, Figure 7 The method comprises the following steps:

[0075] S701, receiving an upgrade instruction sent by a management controller outside the logic controller.

[0076] It should be noted that the execution process of S701 is described in S601, which will not be described here.

[0077] S702, determining the target data corresponding to the upgrade instruction stored in the user flash.

[0078] The upgrade instruction includes an upgrade package specified by the management controller, and the management controller instructs to write data in the upgrade package to the user flash memory. The target data is data in the user flash memory corresponding to the data in the upgrade package. The essence of the upgrade process is to replace the target data with the data in the upgrade package.

[0079] For example, the target data is parameter A, and the data in the upgrade package is parameter B. Parameter A and parameter B are of the same parameter type. In the upgrade process, parameter A of the same parameter type as parameter B in the user flash memory is determined according to the parameter type of parameter B, and then the replacement process is performed.

[0080] S703, erase the target data, and perform data rewriting on the user flash memory according to the upgrade instruction to perform the upgrade process.

[0081] For example, the flash upgrade controller generates an erase instruction to trigger the erasure of the target data, and rewrites the data in the user flash memory to perform the upgrade process after the erasure is completed.

[0082] Optionally, the flash upgrade controller generates a full erase instruction to erase all data in the user flash memory.

[0083] S704, read the pin information of the status register, and determine the upgrade result according to the pin information.

[0084] For example, the status register indicates different upgrade results through different pin information.

[0085] Optionally, the status register indicates the upgrade result of the configuration flash memory or the user flash memory through different pin information.

[0086] Optionally, a mapping relationship between the pin information and the upgrade result is configured in advance, and the corresponding upgrade result is determined according to the mapping relationship and the pin information.

[0087] S705, if the upgrade result is upgrade failure, the flash information storage in the flash information storage is sent to the bus upgrade controller through the retry controller, so that the bus upgrade controller instructs the flash upgrade controller to perform the upgrade retry process on the user flash memory.

[0088] In an example, the retry controller sends the flash information stored in the flash information storage to the bus upgrade controller, including: determining a retry threshold; determining an upgrade result by the retry controller; determining a user flash upgrade retry number by the retry controller if the upgrade result is upgrade failure; reading the stored information from the flash information storage by the retry controller if the upgrade retry number is less than or equal to the threshold; determining the flash information corresponding to the user flash from the stored information by the retry controller; determining a verification parameter of the flash information by the retry controller, the verification parameter including a flash corresponding to the flash information and / or a format of the flash information; performing verification processing on the verification parameter of the flash information by the retry controller to obtain a verification result, the verification result being verification passed or verification failed; and sending the flash information to the bus upgrade controller by the retry controller if the verification result is verification passed.

[0089] In an example, the retry threshold represents an upper limit of the upgrade retry number, and the retry threshold avoids the problem of excessive upgrade retry number leading to excessive cost.

[0090] In an example, if the current upgrade retry number is greater than the retry threshold, a fuse is triggered and the management controller is notified of the upgrade failure, so that the management controller changes the upgrade strategy.

[0091] In an example, if the fuse is triggered, log information of the current upgrade processing and the upgrade retry is obtained, the log information and the upgrade instruction are input into a prediction model to obtain a cause of the upgrade retry failure and a corresponding solution, wherein the prediction model is obtained by training historical data.

[0092] In an example, if the upgrade retry number is less than or equal to the threshold, it means that the upgrade retry number is within a controllable range, and further upgrade retry can be performed.

[0093] In an example, the flash information storage can store multiple types of information, and the flash information corresponding to the user flash is obtained by screening the information stored in the flash information storage during the upgrade retry.

[0094] In an example, the information stored in the flash information storage is grouped according to fields, each group corresponds to a field information, and the type of data is distinguished by the field information, so that the flash information corresponding to the user flash is accurately determined.

[0095] The flash information in the verification parameter corresponds to the memory, which indicates that the flash information is from the user flash or the configuration flash. The format of the flash information in the verification parameter is used to verify whether the format of the flash information stored in the memory is a format that can be recognized by the bus upgrade controller or the flash information memory. The verification processing is performed through the verification parameter to improve the accuracy of the flash information, thereby improving the reliability of the upgrade management.

[0096] Next, the application is described in combination with Figure 8 The upgrade retry is described.

[0097] Figure 8 The schematic diagram of the upgrade retry provided by the application is shown in the figure. Figure 8 As shown in the figure, the management controller sends an upgrade instruction to trigger the start of the upgrade, reads the status register according to the preset period. When the status information is not busy and not failed, the next step is performed, otherwise the upgrade fails. The erase instruction is sent to trigger the flash erase, and after the state is detected ready, the configuration flash starting address is written. The writing is performed page by page, and after each page is written, the status register is read. After the configuration flash area writing is completed, the target address is switched to the user flash address. The upgrade completion instruction is sent to close the upgrade channel, and the upgrade operation of the logic controller is completed. When the user flash upgrade fails, the retry controller is instructed to perform the upgrade retry.

[0098] In combination with the scene example, first, the management controller issues an upgrade instruction through the integrated circuit bus, and the logic controller synchronously stores the identifier in the user flash in the flash information memory. During the upgrade process, when the status register is read incorrectly (i.e., when the upgrade fails), the flash upgrade controller immediately sends a FAIL_FLAG signal to the retry controller to trigger the upgrade retry, extracts the identifier from the flash information memory to the bus upgrade controller, and drives the bus upgrade controller to issue again to perform the upgrade. If the upgrade fails again, the retry controller drives the bus upgrade controller to perform the upgrade again, and if the number of failures exceeds the retry number threshold, the fuse is triggered, and the management controller is notified of the upgrade failure.

[0099] In this feasible implementation manner, the upgrade number and the verification parameter are used for verification, which can improve the effectiveness of the upgrade processing, thereby improving the reliability of the upgrade management.

[0100] In a feasible implementation manner, the logic controller further includes a configuration flash. If the upgrade result is upgrade failure, the flash upgrade method further includes: generating a retry instruction through the retry controller; sending the retry instruction to the bus upgrade controller through the retry controller, so that the bus upgrade controller sends the retry instruction to the flash upgrade controller to perform the upgrade retry processing on the configuration flash.

[0101] Exemplarily, the upgrade processing is to upgrade the configuration flash memory first, and then upgrade the user flash memory, and in the case of upgrade failure of the configuration flash memory, the identification in the user flash memory can be used for verification due to the fact that the identification in the user flash memory is not erased.

[0102] In combination with the scene example, in the case of upgrade failure of the configuration flash memory, the retry controller does not need to read the flash memory information from the flash memory information storage, and can directly trigger the bus upgrade controller to perform upgrade retry.

[0103] In this feasible implementation manner, the identification in the user flash memory is used for upgrade retry of the configuration flash memory, thereby reducing the operation of retry, and further improving the reliability of upgrade management.

[0104] In a feasible implementation manner, if the upgrade result is upgrade success, the method further includes: determining a standard check value; determining original data from the user flash memory and / or the configuration flash memory, and performing calculation processing on the original data according to a check algorithm to obtain an original check value; comparing the original check value and the standard check value to perform cyclic redundancy check to obtain a second check result, the second check result being check pass or check fail; and if the second check result is check fail, performing upgrade retry processing.

[0105] Exemplarily, the cyclic redundancy check is a kind of error detection coding based on polynomial division.

[0106] Exemplarily, the upgrade result is upgrade success, which indicates that the data in the upgrade package has been written into the user flash memory and / or the configuration flash memory, and the cyclic redundancy check is used to determine whether there is an exception in the writing process, i.e., whether the actually written data is the target written data.

[0107] Exemplarily, the standard check value is a check value corresponding to the target written data, the original data is the actually written flash memory data, and the original check value obtained by performing calculation processing on the original data through the check algorithm is the actual check value. By comparing the original check value and the standard check value, it can be determined whether the actually written data is correct, and if not, further upgrade retry processing is performed.

[0108] Optionally, the management controller generates the upgrade instruction and simultaneously generates a corresponding standard check value.

[0109] In this feasible implementation manner, through the cyclic redundancy check, it can be ensured that the actually written memory data is correct data, thereby improving the reliability of upgrade management.

[0110] In a feasible implementation manner, after receiving the upgrade instruction sent by the management controller outside the receiving logic controller, the method further includes: determining flash memory information of the user flash memory, and storing the flash memory information to a flash memory information storage.

[0111] For example, the logic controller triggers the storage of flash memory information upon receiving an upgrade command.

[0112] As illustrated by the scenario example, the flash memory information in the user's flash memory may change. Retrieving the latest flash memory information from the user's flash memory in real time upon receiving an upgrade command ensures the validity of the flash memory message, allowing the latest flash memory information to be used during upgrade retries.

[0113] In this feasible implementation, by obtaining the latest flash memory information from the user's flash memory in real time when receiving upgrade instructions, the validity of flash memory messages can be ensured, thereby improving the reliability of upgrade management.

[0114] Through the above description of the embodiments, those skilled in the art can clearly understand that the methods according to the above embodiments can be implemented by means of software plus necessary general-purpose hardware platforms. Of course, they can also be implemented by hardware, but in many cases the former is a better implementation method.

[0115] Figure 9 This is a schematic diagram of the structure of a flash memory upgrade device provided in an embodiment of this application. Figure 9 As shown, embodiments of this application also provide a flash memory upgrade device 90, which may include: a receiving module 91, an upgrade module 92, and a management module 93, wherein...

[0116] The receiving module 91 is used to receive upgrade commands sent by the management controller outside the logic controller.

[0117] Upgrade module 92 is used to upgrade the user's flash memory according to the upgrade instruction and determine the upgrade result.

[0118] The management module 93 is used to send the flash memory information stored in the flash memory to the bus upgrade controller through the retry controller if the upgrade result is an upgrade failure, so that the bus upgrade controller instructs the flash memory upgrade controller to perform upgrade retry processing on the user flash memory.

[0119] Optionally, the receiving module 91 can perform... Figure 6 S601 in the embodiment.

[0120] Optionally, upgrade module 92 can be executed. Figure 6 S602 in the embodiment.

[0121] Optionally, management module 93 can execute Figure 6 S603 in the embodiment.

[0122] It should be noted that the flash memory upgrade device shown in the embodiments of this application can execute the technical solution shown in the above method embodiments, and its implementation principle and beneficial effects are similar, so they will not be described again here.

[0123] In a possible implementation, the upgrading module 92 is specifically configured to:

[0124] determine target data corresponding to the upgrading instruction in the user flash memory;
