[0039] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all of the embodiments of the present application.

[0040] The components of the embodiments of the present application generally described and illustrated herein can be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by a person skilled in the art without creative work shall fall within the scope of protection of the present application.

[0041] Hereinafter, the terms "include", "have", and their conjugates in various embodiments of the present application are only intended to denote a certain characteristic, number, step, operation, element, component, or combination of the foregoing, and should not be construed as excluding the presence or addition of one or more other characteristics, numbers, steps, operations, elements, components, or combinations of the foregoing. In addition, the terms "first", "second", "third", and the like are only used to distinguish descriptions, and cannot be understood as indicating or implying relative importance.

[0042] Unless specifically defined, all other technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which various embodiments of the present application belong. The terminology used herein (e.g., the terminology used in the description of the figures) is for the purpose of describing particular embodiments only and is not intended to be limiting. Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which various embodiments of the present application belong. The terminology used herein, such as that found in the dictionary, will be interpreted as having a meaning that is the same as commonly understood in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless clearly defined specifically in various embodiments of the present application.

[0043] Some embodiments of the present application are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments can be combined with each other unless there is a conflict.

[0044] In the development process of the solid state disk, the developer needs to locate any problems that occur during the test, including read / write errors, etc. For read / write errors, the developer needs to confirm whether the problem is caused by defects in the firmware code or by serious wear and tear of the NAND particles. However, the current test process is recorded and stored internally by the NAND, especially during the firmware development stage, sometimes the loss of NAND particle wear record cannot be recovered. In other words, the existing test process does not pay attention to the preservation of the wear and tear of the solid state disk, resulting in that when a large number of read / write errors occur in the solid state disk, the developer cannot determine whether the problem is caused by serious wear and tear of the NAND particles because there is often no previous wear record, so additional effort is needed to locate the fault, which greatly reduces the test development efficiency, etc.

[0045] To this end, the present application provides a solid state disk state data processing method, which can be applied to the development and test process of the solid state disk, and can realize automatic test positioning and improve the development and test efficiency, etc.

[0046] Please refer to Figure 1 , exemplary, the solid state disk state data processing method comprises steps S110-S130:

[0047] S110, when detecting that the data structure version information of the current firmware in the solid state disk is inconsistent with the target version information during firmware upgrade, obtaining the encoding information of the solid state disk.

[0048] During firmware development, a version number is set for each data structure, and each firmware will contain the version number information of the data structure it uses, and it will be written into the NAND in the firmware hard disk during mass production, and it can be read through the custom command defined by the manufacturer.

[0049] In the firmware development stage, the data structure of the data saved on the NAND will change frequently, resulting in incompatible data between the firmware of the previous and next versions, so it is necessary to frequently clear all information in the NAND, including the wear record of each NAND grain, and the wear record and other information are not recoverable after being cleared. Therefore, according to the version information of the data structure at each firmware upgrade, the embodiment determines whether to transfer the wear data in the solid state disk to the external environment to ensure that the wear condition of the solid state disk throughout the life cycle can be recorded in real time.

[0050] The encoding information of the solid state disk is used to uniquely identify each solid state disk, for example, can include but is not limited to the master control identification code, etc. Generally, the master control of the solid state disk has a factory-set universal unique identification code, which can be read through the vendor-defined command provided by the firmware, so that the wear information of the solid state disk can be bound with the master control identification code to realize the tracking of the wear information.

[0051] In addition, for some solid state disks without unique identification code of the master control, a unique encoding information can be set for it, for example, the disk model, disk capacity and disk serial number of the solid state disk can be combined in sequence to obtain a combined encoding, and the combined encoding is used as the disk serial number of the solid state disk and is pasted or set on the surface of the hard disk.

[0052] For the above step S110, exemplarily, when the firmware of the solid state disk is upgraded (secondary card opening) using the mass production tool, first, the version number of the data structure used by the current firmware of the solid state disk is read to confirm whether it is consistent with the version number of the data structure of the target version to be upgraded. If it is not consistent, it means that the internal information of the NAND has the risk of being cleared, so the wear data in the solid state disk is transferred externally, and then the subsequent operation is performed. Alternatively, if the data structure version information of the current firmware in the solid state disk is consistent with the target version information, the next operation can be directly performed, that is, the firmware of the solid state disk is upgraded.

[0053] In an embodiment, as shown in Figure 2 The encoding information of the solid state disk is used to uniquely identify each solid state disk, for example, can include but is not limited to the master control identification code, etc. Generally, the master control of the solid state disk has a factory-set universal unique identification code, which can be read through the vendor-defined command provided by the firmware, so that the wear information of the solid state disk can be bound with the master control identification code to realize the tracking of the wear information.

[0054] S210, a preset instruction is sent to read the master control identification code of the solid state disk.

[0055] S220, if the reading is successful, the read master control identification code is used as the encoding information of the solid state disk.

[0056] S230, if the reading fails, a camera device is used to shoot the disk surface of the solid state disk to obtain a disk surface image.

[0057] S240, identifying a disk serial number arranged at a preset position in the disk surface image, taking the disk serial number as the encoding information of the solid state disk.

[0058] Exemplarily, when the master identification code fails to be read through the vendor-defined instruction, it means that the solid state disk does not have a master identification code; then, the disk surface of the solid state disk is shot by the camera to obtain the disk serial number through image recognition.

[0059] For example, as shown in Figure 3 For the solid state disk without a master identification code, the predefined disk serial number is arranged on the disk surface of the solid state disk, and the shooting angle of the camera can be set at the preset position where the disk serial number is arranged to obtain a clear image. It can be understood that the model for serial number recognition can be pre-trained.

[0060] S120, reading the flash wear data of the solid state disk and storing the flash wear data and the encoding information in the external storage medium; wherein the flash wear data is used to record the wear state of the solid state disk in the development test cycle.

[0061] After reading the flash wear data of the solid state disk, it is bound with the read master identification code or disk serial number and saved to the designated external storage medium, such as a non-volatile storage structure such as a Flash, TF card, SD card, and then step S130 is executed.

[0062] S130, then performing firmware upgrade on the solid state disk.

[0063] Therefore, after storing the flash wear data of the solid state disk to the external storage, subsequent firmware code writing and other operations are continued until the firmware upgrade is completed.

[0064] In addition, in order to ensure the reliability of the firmware after the firmware upgrade, a large amount of read and write operations need to be further performed on the solid state disk to ensure that the firmware code can work normally under a large pressure and long time output input service.

[0065] Further, as shown in Figure 4 The solid state disk state data processing method further comprises:

[0066] S140, when performing firmware verification, if the solid state disk has read / write error, obtaining the flash wear data of the solid state disk from the external storage medium according to the encoding information of the solid state disk.

[0067] S150, performing read error fault analysis on the solid state disk according to the flash wear data.

[0068] According to practical experience, NAND wear is serious, and a large number of read errors often occur in the test process, which is caused by the end of life of NAND particles, and is not a design problem of the hardware and software of the solid state disk. Based on this, when a certain number of read and write errors occur in the test, the flash wear data of the solid state disk is obtained from the external storage medium, so as to quickly judge whether the current solid state disk has serious wear problem, and then it can be determined whether the next fault analysis operation is needed, which can improve the test efficiency and the like.

[0069] As shown in Figure 5 read error fault analysis includes:

[0070] S310, detecting whether the read flash wear data exceeds a preset threshold.

[0071] The maximum wear limit of different types of solid state disks is different, and the preset threshold can be set according to a large number of test results and experience values of actual types of solid state disks, which is not limited here. If the preset threshold is exceeded, it means that the solid state disk has reached a certain degree of wear and has entered the end of life, and step S320 is executed, otherwise step S330 is executed.

[0072] S320, if the preset threshold is exceeded, it is determined that the solid state disk is seriously worn, and the test operation of the solid state disk is stopped.

[0073] S330, if the preset threshold is not exceeded, the firmware code of the solid state disk is debugged to locate the code fault.

[0074] It can be understood that if it is determined that the solid state disk is seriously worn, in order to reduce unnecessary effort, the solid state disk can be discarded and other good state disks are used for retesting; if the solid state disk is still in a usable state, it needs to be further considered whether it is caused by the defects of the firmware code and the design of the hardware and software, and the reason for the read error can be checked by debugging the firmware code.

[0075] As an optional solution, after obtaining the existing flash wear data in the external storage medium, the method can further include:

[0076] read the current flash wear data of the solid state disk, and accumulate the current flash wear data and the historical flash wear data obtained from the external storage medium to obtain flash wear accumulation data; then, according to the flash wear accumulation data, the read error fault positioning operation is performed.

[0077] It can be understood that the principle of using flash wear accumulation data for fault judgment is the same as the principle of using flash wear data for read error fault analysis described above, so it will not be described again here. Considering that the current firmware verification being performed will also generate corresponding wear records, therefore, by accumulating the historical flash wear data and the latest recorded current flash wear data, a more accurate wear condition can be obtained, which can improve the accuracy of fault analysis, etc.

[0078] The solid state disk state data processing method of the embodiment can determine whether to save the wear data of the storage unit to the external storage medium according to the data structure version information of the firmware when upgrading the hard disk, and bind the wear data by obtaining the encoding identification information such as the master control identification code or the disk serial number of the solid state disk when necessary, so as to realize wear information tracking. By saving the wear data to the external storage medium, information loss can be prevented, and the wear state of the solid state disk can be monitored conveniently. On the other hand, when a large number of read / write errors occur in the solid state disk, it can be quickly judged whether it is caused by serious NAND wear or defects caused by the firmware code itself, which can improve the test efficiency, etc.
