Technical Field

[0001] This invention relates to the field of firmware flashing technology, and in particular to a firmware flashing method that supports multiple types of cameras. Background Technology

[0002] Firmware flashing involves the technical process of writing software code into the non-volatile memory of a target hardware device. It is commonly used in electronic product manufacturing, equipment upgrades, and maintenance. This technical field includes the selection of flashing tools and interfaces, adaptation of flashing protocols, identification of the target device's storage structure, verification of data integrity, and error detection and verification mechanisms during the flashing process. Traditional firmware flashing methods supporting multiple camera types refer to the firmware flashing methods used to write corresponding firmware programs into multiple camera devices with different models, functions, or communication interfaces.

[0003] In existing technologies, firmware burning processes rely on fixed scripts and fixed parameter configurations. Changes in device types and interfaces make it difficult to effectively adapt communication characteristics. Handshakes and signal interactions often result in incomplete identification. Command responses and status changes lack regularity. The triggering and sequential processing of different commands are not universal. Script structures and parameter descriptions are frequently adjusted with changes in device models. Error tracing efficiency is low when storage area status feedback is abnormal. Operations are prone to process disorder and parameter mismatch, further affecting the accuracy and reliability of firmware burning for multiple camera models and reducing overall production efficiency.

[0026] In S3, page writing refers to writing firmware data in batches according to the "pages" supported by the memory, writing one page of data at a time. This is commonly used in memory chips such as Flash and EEPROM. Response connection process refers to how the device's response signals are sequentially connected with the master control command process between different commands to ensure that the next operation is reasonably connected based on the previous response. Process control signals refer to key signals used to indicate process progress or interruption, such as process start, operation success, error return, process end, etc. The correspondence between status signals refers to how changes in device status signals before and after different commands or stages correspond to the order of command process progression.

[0029] like Figure 2 As shown, the specific steps for obtaining the communication feature structure set are as follows: S101: Based on multiple types of communication interfaces, analyze the handshake signals between the camera device and the main controller, compare the arrangement of the start bit, stop bit and check bit of the response frame in each protocol, determine the relationship between the boundaries of each field in the frame and the sequence synchronization, combine the differences in the order and continuity of the fields in the signal stream frame structure, optimize the field boundary calibration method, and obtain the frame boundary distribution characteristics. Based on the analysis of handshake signals between devices and the master controller in various communication interfaces, it is necessary to compare the signal structures of each communication protocol separately. Taking UART communication as an example, in signal interaction, the handshake frame usually starts with a low level and ends with a high level, with the check bit following the data field. By recording the handshake signal frames returned by multiple devices using an oscilloscope, the slight differences in the duration of the start and stop bits at the same speed can be observed. It is necessary to compare the signal change trends of each segment, mark the level transition points before and after the start bit, and statistically analyze the average time position difference of the start and stop bits in each data packet of the handshake signal to determine the fixity of the frame start and end marks at the protocol layer. In the I2C protocol, the start bit is the master controller pulling down the data line while keeping the clock line high, and the stop bit is the master controller releasing the data line to high. In the SPI protocol, the start of the frame is defined by the transition of the chip select signal level from high to low. It is necessary to record the logic change points on each channel sequentially and mark the start and end positions of the corresponding frames to further analyze the check bits. The displacement difference between bits and data fields is used to extract the field structure according to the data grouping order of each frame, and then the first and last bit positions of each field are marked one by one. In terms of sample selection, no less than 1,000 frames of data are collected for each interface. By observing the frequency position difference of the start and stop flags, the difference between the first and last positions of the fields is statistically analyzed. When the change in the start position of the same field in two adjacent frames is less than three bits, the field boundary is determined to be stable. When the change range exceeds six bits, it is recorded as a boundary drift field. By constructing a frame structure table, the field arrangement patterns of each protocol are collected, and the minimum, maximum, and median values ​​of the number of bits between the front and back of the field are extracted to summarize the actual position range of each field in the frame. The frame structure is compared in parallel during the handshake process. For the part with large fluctuations in field position, the boundary sliding positioning method is applied. The communication protocol specification is used to confirm whether it belongs to control bit, address bit, or check bit. The field boundary determination method is optimized under different protocol conditions to form frame boundary distribution characteristics, which are used to identify the field arrangement patterns in the data stream.

[0030] S102: Based on the frame boundary distribution characteristics, determine the arrangement changes of address fields in the response data stream under the action of the probe command, calculate the progressive relationship of address fields in continuous data frames, filter the sequential characteristics of address fields in each packet, and compare the regularity of address fields in each packet structure by combining the corresponding situation of field arrangement before and after, to obtain the address jump sequence characteristics. Under the action of the probe command, the address fields contained in the communication response data are extracted sequentially. First, the position of the identified address field in each frame is read, and its byte offset in the data frame is marked. For example, when an industrial camera communicates via the SPI interface, the common address fields are located in the 3rd and 4th bytes. By comparing the value changes of the field at this position in consecutive frames, the start and end values ​​corresponding to the address in each frame are extracted. In 16 groups of communication responses, the corresponding address field values ​​are 0, 128, 256, and 384, respectively, indicating that the address increases in units of 128 in each data response. Therefore, it is determined that the device adopts page write mode, and the page size is 128 bytes. If the address field in some frames jumps irregularly, such as jumping from 512 to 768 and then back to 640, the number of jumps needs to be counted, and the address change amplitude between adjacent frames needs to be calculated. Fields with a change amplitude of less than 64 bytes are classified as abnormal address segments. When extracting the data packet structure, the field arrangement order in each frame is extracted by comparing with the previously identified frame boundaries. The number of bytes before and after the address field is recorded in each frame. If the address field is followed by the data field and preceded by a fixed command field in most frames, the field arrangement is considered stable. Then, the data packet structure under multiple interfaces is compared. For example, in the USB interface, the address field of the response frame is usually in the 5th to 6th byte position. If the offset of the address field relative to the start position in the data structure remains consistent, it is extracted as a stable structural feature. Conversely, if the field jumps, a grouping model is established to sequentially label the address field values ​​in all frames and construct a jump sequence. The jump sequence is organized according to the frame order, and the jump amplitude is clustered to summarize the change pattern of the address field. The jump step size value with the highest frequency is recorded, and a complete sequence feature of address jump is constructed for each jump segment.

[0031] S103: Based on the address transition sequence characteristics, determine the field distribution of the signal segment triggered by multiple sets of probe commands, calculate the transition relationship between the frame synchronization flag and the field sequence in each signal segment, optimize the address field progression and frame structure matching method, identify typical structural characteristics, and obtain the communication feature structure set; Under the action of multiple sets of probe commands, the communication data returned by the device is divided into signal segments according to the time sequence. Each signal segment corresponds to multiple complete data frames. First, the position of the synchronization flag field is identified in each signal segment. For example, in the GMSL protocol, a fixed 0xAA is used as the frame header flag. By comparing whether multiple frame headers appear continuously and stably, it is determined whether the data frame synchronization flag in the signal segment is stable. The field arrangement order and address field position are extracted sequentially for the data frames in each segment. The starting offset of the fields in each segment is recorded, and the field offset difference between adjacent data frames is statistically analyzed. If the fields maintain a fixed order within three bytes, it is determined that the field arrangement is stable. If the field position in a segment changes frequently, with more than five jumps, it is recorded as an unstable field segment. The overall structure of the segments is analyzed to filter out segments with stable address field jump amplitudes and stable field arrangement. For each segment with consistent data, the frequency of the synchronization flag is recorded, and abrupt changes in field positions are marked. By comparing the relationship between changes in field arrangement and the stability of the synchronization flag, the correspondence between the field order, synchronization flag position, and transition position of representative communication structures in typical signal segments is extracted. Combining field length and transition interval, typical structural patterns under different interfaces are summarized, and the combination of representative structural fields is identified. In the MIPI interface test, a typical structure appears where the synchronization field is fixed as a preamble 0x5A, the address field is located in the 3rd and 4th bytes, and the data field starts from the 5th byte and continues for 16 bytes. Through analysis and comparison of this format, it is classified as one of the typical structures. Based on this method, a communication structure index table is constructed, integrating the three dimensions of field position, transition mode, and frame header identifier to generate a set of communication feature structures.

[0032] like Figure 3 As shown, the specific steps for obtaining the command distribution characteristic set are as follows: S201: Based on the communication feature structure set, determine the field arrangement order of the erase command and write command response frames, compare the preceding and following positions of the fields under each command, filter the transformation features of the fields in the response process, establish an index based on the correspondence between the field appearance order and the command type, and obtain the command order distribution sequence. In the response frames received by the master device after the erase and write commands are issued, the field order is compared, and the field name and its byte offset position in the frame are extracted frame by frame. The field order in the erase command response frame is recorded as sequence A, and the field order in the write command response frame is recorded as sequence B. The index positions of the fields before and after each field are marked, and it is determined whether the fields in the two sets of command response structures have a fixed sequential dependency relationship. For example, in an industrial camera using the SPI protocol, the leading field in the erase response frame is the command code, followed by the status field, and then the check field. In the write response frame, it is the command code, address field, data field, status field, and check field. Combining actual signal observation samples, the offset value and position order of each field relative to the leading field in 100 frames of data are compared to filter the relative changes of fields in different commands. When a field is at the beginning in the erase frame and... When a field appears more than two times in a write frame, it is designated as a structural transformation field and marked. Fields that appear more than 70% of the time in the response frame are selected as the main transformation set. In this set, the content types of the fields are further compared. For example, a status field may be a single byte 0x00 or 0x01 in the erase response and a two-byte combination 0x000x80 in the write response. The extended form of the field is identified by matching the number of bytes in the field value with the content pattern. All forms of the field appearing in the two command responses are recorded to form a field response difference table. Then, a mapping index is established between the field appearance sequence number and the corresponding command type. The field positions and order in different command response frame structures are abstracted into a command field index set. By matching the order of the fields in the set with the commands, a mapping relationship between command type and field order is constructed, generating a command order distribution sequence.

[0033] S202: Based on the command sequence distribution, determine the change characteristics of the status bits during command interaction, calculate the combination of status bits before and after each operation stage, optimize the signal transition node identifier during each stage transition, and obtain the stage signal transition information by comparing the distribution characteristics of the operation stage in the erase and write process. By comparing the changes in status bits in each stage, the order of occurrence of status fields in the response frame is extracted and the status values ​​are recorded. For each group of operation stages, such as erase initialization, erase complete, write start, data writing in progress, and write complete, the value combinations of status fields in each stage are statistically analyzed. In a typical erase process, the status value is recorded as 0x01 indicating erase in progress and 0x00 indicating completion. In the write stage, the status changes from 0x03 to 0x00, and then to 0x80. The extracted values ​​are paired one-to-one with the command types in the frame sequence. The time point of each transition node and the corresponding operation stage are located on the frame timeline. If the duration of a certain value is shorter than the previous status value during the change of status bit values, it is recorded as a high-frequency transition node. All transition nodes are recorded. The current positions are summarized, and transition nodes that appear more than three times consecutively are marked as stable state change characteristics. The transition sequence is then categorized into erase and write phases. By referring to the phase signal transition rule table, and based on the distribution range of state values ​​in different operation phases, it is determined which values ​​are phase transition flags. In actual analysis, if a value appears more than 80% of the time in the erase phase but never appears in the write phase, it is considered to belong to the erase phase-specific state bit. By recording the occurrence phase of each state value, a correspondence table between state fields and phases is compiled. The command frame type, field order, and field content before and after the state transition are compared. By connecting the signal change points in chronological order, the phase signal transition information is summarized.

[0034] S203: Based on the stage signal conversion information, determine the position and field relationship of the verification signal in each command response frame, analyze the mapping of the verification field and status bit combination in the command flow, adjust the classification criteria for field attribution determination, and obtain the command distribution characteristic set; In each command response frame, the starting position of the checksum field and the position of the status field are extracted. The number of bytes, starting offset, and order of fields before and after the checksum field in each frame are marked. In a typical USB interface write process, the checksum field appears in the second-to-last byte, preceded by the status field. Combining the changing values ​​of the status field and checksum field, the command type is recorded group by group for different combinations. For example, when the status field is 0x00, the checksum field is 0xA5; when the status field is 0x80, the checksum field is 0x5A. The combinations are paired with the command types, and the field combination forms under different stages of the same command are compared. All field combinations are extracted and their frequency of occurrence is counted. The records that appear more than 60% of the time in the combination are designated as the main mapping combination. The field combination characteristics corresponding to each command are marked in the mapping table. The field attribution relationship in the combination is further classified. If a field appears in all three commands and its position is fixed, it is classified as a shared field. If a field only appears in the write operation, it is classified as a write-specific field. Field classification criteria are then established according to field attribution. Fields in all response frames are reclassified and reorganized. The position, value combination, and co-occurrence of status fields and verification fields under each type of command are analyzed. Based on position comparison, value matching, and command attribution relationship, the field classification criteria are adjusted and the corresponding structure of command type and field set is reorganized to obtain the command distribution characteristic set.

[0035] like Figure 4 As shown, the specific steps for obtaining the programming instruction sequence are as follows: S301: Based on the command distribution feature set, optimize the response connection process between page write command and erase command, compare the status bits and field order association in the response frames of the two types of commands, determine the connection relationship of the start and end flags of adjacent command response segments, calculate the consistency of state transition between segments, and check the frame boundary alignment result to obtain the process connection segment sequence. When analyzing the response frames between page write and erase commands, it is necessary to compare the status fields and their order in the response frames corresponding to the two types of commands. First, the field sequence in the response frame for each type of command is recorded. Taking the page write command as an example, the order of the status field, address field, data field, and checksum field in the command frame structure is extracted. In the erase command, the number of preceding fields for the status field and their offset within the frame are recorded. The order of the fields in the two command types is compared, listing whether each status field is preceding or following the previous one, and determining whether the field order remains consistent. In each of the 100 sample frames, the number of times the position of a field is repeated is counted. When the status field is located in the 3rd byte in the write response and in the 2nd byte in the erase response, and this is accompanied by changes in the relative positions of other fields, it is recorded as a sequential change structure. The difference structures are aggregated to summarize the field order change type, and then the correspondence between the start and end flags between command response segments is determined. In specific operations, the byte values ​​corresponding to the start and end flags of each response frame are extracted. For example, erase frames start with 0x55 and end with 0xAA, and write frames start with 0x66. The header, ending with 0xCC, records whether the flags appear consecutively in the frame sequence. If the end flag of the write frame is immediately adjacent to the start flag of the erase frame, and the interval between the two flags is less than 2 bytes, then the two frames are considered to be adjacent command segments in communication. After determining that the start and end flags are successfully matched, the status field values ​​in these two command segments are further checked for transitions. The status values ​​of the last frame of the erase response and the first frame of the write response are extracted. If the status value of the last frame of the erase response is 0x00 and the status value of the first frame of the write response is 0x01, then it is considered a valid status transition. The transition combinations of the status fields of all consecutive command segments are then processed. Statistical analysis is performed to construct a state transition comparison table, recording whether each state change consistently appears at the command switching position. If a certain state change combination appears in more than 80% of the command switching sequences, it is considered that the state transition is consistent. Based on the above structure and state verification, the offset comparison of the boundary fields of the two command frames is performed to determine whether there is a cross-frame alignment misalignment problem. If the interval between the end position of the field and the start position of the field in the next frame is no more than 1 byte, it is considered that the alignment is valid. All command pairs with matching structures and consistent state transitions are summarized to form a sequence of process connection segments.

[0036] S302: Based on the sequence of process connection segments, filter the process control signals formed after the handshake is completed, and make a matching judgment based on the combination of the end flag and status bit in the handshake response frame. Eliminate and remove signal segments that are not related to the erase and write phase to obtain the process node signal set. After analyzing the erase and write command responses, the process enters the flow control signal filtering stage after the handshake interaction ends. First, the start and end field values ​​of the handshake end frame are extracted. In industrial cameras with SPI interfaces, this frame typically ends with the command code 0xAB, while the status field value is fixed at 0x02. By sampling 100 sets of handshake response frames, the frame positions where the 0xAB and 0x02 combination appears are recorded. All communication data segments after the handshake frame are divided, and it is determined whether the above combination exists at the beginning of each data segment. If it exists, it is marked as a handshake completion frame. In all response data after the handshake completion frame, the status field and operation flag field of each data frame are checked frame by frame to see if they conform to the erase operation. For the command sequence during the write phase, frames with a status value of 0xFF or all data fields set to 0x00 are discarded by comparing field contents. These frames do not participate in the erase or write operation and are recorded as irrelevant control signal frames. At the same time, it is determined whether the frame contains an illegal field arrangement. If the status field is located after the 5th byte and the check field is missing, it is further marked as an abnormal frame. The aforementioned irrelevant and abnormal frames are indexed and excluded. The remaining frames are matched for command type based on the combination of status field and data field. All frames that match the erase and write command field structure are renumbered. Valid response frames are summarized, and a flow control node set is constructed, recording their occurrence order, status field value, and frame start and end positions.

[0037] S303: Based on the process node signal set, adjust the logical order of each instruction in the burning process, determine the correspondence between the status signals before and after the command interaction, analyze the process node switching conditions, identify the instruction chain with consistent node order, and obtain the burning instruction connection sequence. The logical order of each instruction in the programming process is adjusted and analyzed. First, the command type, frame structure, start and end flags, and status field values ​​corresponding to each instruction in the current sequence are extracted. The time interval and state transition direction after each instruction is executed are recorded. If the time interval between two instructions exceeds 200 milliseconds and the status field does not change, it is identified as a process blockade point. The command types are compared before and after all process blockade points. If no erase command is found before the write command, the order is adjusted. Based on this, the changes in the status field before and after all command interactions are analyzed to determine whether the status value is stable from 0x01 in the erase stage to 0x03 in the write stage. If this change is within 80%, it is considered a stable state. If the above process occurs, a state correspondence table is established. For each instruction, the combination of its preceding and following states is recorded. Then, combined with the state field sequence recorded in the flow control signal central record, a complete path is constructed for the instruction chain. The state changes, field structure, and command type are combined and compared. The switching conditions of each operation node are identified. For example, the page write command is only started when the state value is 0x00. If the previous instruction returns a state value of 0x03, a state clear command needs to be inserted. All command sequences are organized according to the switching conditions of all nodes. All command chains with consistent order and continuous structure are selected. Their execution logic order, field mapping, and state combination method are recorded to construct the burning instruction connection sequence.

[0038] like Figure 5 As shown, the specific steps for obtaining the protocol adaptation parameter set are as follows: S401: Based on the programming instruction sequence, analyze the operation structure of erase and write commands, determine the field order and logical connection between fields in the data frame, compare the status bit changes and field switching conditions during the command triggering stage, calculate the distribution of field paths under each command, and obtain the operation path feature group. The erase and write commands are analyzed separately. First, the data frame structure of the erase command is recorded. Its field order typically includes five parts: command field, control field, target address field, status field, and checksum field. The data frame structure of the write command includes five parts: command field, target address field, write data field, checksum field, and status field. Comparing the field order in the two command frames, it is found that the control field in the erase command precedes the address field, while in the write command, the control field is omitted, and the data field is inserted after the address field. By calculating the byte spacing between fields and recording their actual offset on the communication bus, a fixed dependency between fields is extracted. For example, if the status field always appears immediately after the checksum field, a sequential dependency is determined. In the analysis of the write command, it is statistically analyzed whether the status field changes value after data writing is completed. If the status field is 0x00 before data writing and becomes 0x03 after writing... If the status changes from 0x01 to 0x00, it is recorded as a status bit transition event. Compare the status bit changes of the erase command. If it changes from 0x01 to 0x00, it is recorded as the identifier value for completing the erase phase. After summarizing all status field transition events, the initial and final values ​​of the status fields when the command is triggered are marked, and the field switching conditions are statistically analyzed. For example, in the SPI interface write operation, data field transmission is allowed only when the status field value is 0x00; otherwise, the write command has no response. A table is established to correspond to the field values ​​and trigger conditions. The offset paths of all fields during the command execution phase are extracted, and the start and end addresses of each field in the command data frame are recorded. By statistically analyzing the frequency and position range of field paths in erase and write commands, the typical offset range of each field under different commands is extracted. The start and end byte ranges of the fields are grouped by command for path distribution and organized to form a data structure set containing field order, dependency relationship, status transition, and path offset, thus obtaining the operation path feature group.

[0039] S402: Based on the operation path feature group, analyze the coordination between interface type and communication interval signal, determine the correspondence between the intra-interface interval segment of each interface communication frame and the command stage, identify the control field that is synchronized with the writing and verification process, adjust the arrangement order of the fields in the script and the execution link, and obtain the instruction link parameter set; To extract the corresponding interface type and communication interval characteristics from different communication interfaces, first determine the time interval between command frames under interfaces such as USB, I2C, SPI, and UART. Record the start and end timestamps of each frame in the test data, calculate the length of the idle time period between adjacent frames, and record the stage position where the idle segment appears. For example, the average idle time between write and verification in the USB interface is 4ms, while the average idle time in the same stage in I2C is 2ms. Extract the time value of the idle segment and mark the command type that appears before and after it. If the idle segment always appears in the stage after write and before verification, mark this time period as the write-verification gap. Further determine whether there is a specific control field in the idle segment. For example, in the SPI interface, it is observed that the master sends a 0xFF padding byte in the idle segment to maintain the communication rhythm. At the same time, obtain whether there is a specific control field from the response frame. In the event of a change in the value of a verification field or a rewrite of a status field, if the field exists, it indicates that the control field is used for synchronization status. For this type of control field, its occurrence position, byte content, and context command type are recorded. By judging whether it appears in most write or verification stages, if the frequency of occurrence is greater than 80%, it is marked as a synchronization control field. The occurrence positions of all control fields are summarized, and the original burning script is structurally parsed. The order of fields in the script is recorded. For example, command fields, address fields, and data fields appear in a fixed key-value order in the JSON structure script. The field order is adjusted so that the write command is immediately followed by the verification command and the status field is arranged after the verification field. All field paths are aligned with the execution stage, and delay control statements are marked according to the communication interval time value. A chain correspondence between fields and execution order is formed, forming an instruction link parameter set.

[0040] S403: Based on the instruction link parameter set, analyze the mapping and position of parameter fields within the script structure, determine the association structure between each parameter group and the link, calculate the dependency characteristics between parameter segments and path segments, and obtain the protocol adaptation parameter group. To perform field mapping analysis on the script structure, firstly extract the position key values ​​of each parameter field in the burning script structure, including command type, target address, written data, verification method and delay parameters, etc., and record the path of the parameter field in the script. For example, in the nested JSON structure, the path of the written command field is root.commands[2].data.address. Decompose each path segment and mark its corresponding parameter type. Group the command type and its subordinate parameter segments as a group of parameters. Extract the structure in all command segments. Record the path depth, number of fields and field order for each group of parameters. Determine whether the field arrangement is consistent. If the data, verify, and de parameters in a certain written command segment are not consistent, the path is not consistent. If the order of the lay fields differs from that in the verification command segment, it is marked as an inconsistent structure. The structure of the inconsistent script segment is adjusted to ensure that the parameter structure of all command segments is consistent. Then, the parameter segment path is mapped to the execution path in the command link. It is analyzed whether the order of the fields in the command execution path is consistent with the order of the parameters in the script structure. If there is a field whose path order is earlier than the script parameter arrangement, the field is moved to before the command field in the script. A mapping table between path and parameter is established. After comparing the structure of all command segments, the consistency ratio of field paths is summarized. If the ratio exceeds 85%, the path alignment is considered successful. All parameter paths, field positions and link mapping relationships are extracted, and a protocol adaptation parameter group with field structure, link position and parameter mapping is compiled.

[0041] like Figure 6 As shown, the specific steps for obtaining the write control optimization adjustment results are as follows: S501: Based on the protocol adaptation parameter group, determine the status feedback returned by each storage area in the write operation, compare the structural characteristics of the feedback signal with the distribution of abnormal segments, filter the storage segments where the status signal changes, determine the segment index where the abnormal feedback occurs continuously, and obtain the abnormal storage structure set. During the write operation, status feedback is extracted from the response frames after each write command according to the write address range. The byte offset position and content value of the status field in each response frame are recorded. In a typical EEPROM write operation, after writing 128 bytes per page, the status field value of the response frame is read. A status value of 0x00 indicates a successful write, while a return value of 0x03 or 0xFF indicates an error in the current segment. A page address list is constructed according to address order, and the status value after each page is written is recorded at the corresponding address index. By comparing the feedback results of all address pages, the address range where non-zero status values ​​occur is calculated and consecutive page segments are marked. Page segments with consecutive abnormal statuses are defined as abnormal feedback segments, for example, addresses from 0x1000 to 0x120. If four consecutive pages return a status of 0xFF, it is marked as an abnormal segment E1. For each abnormal segment, its starting address, page number, and number of abnormal occurrences are recorded. The structure of the status field in the segment is then compared with the structure in the normal segment to determine whether there are missing fields, position offsets, or changes in the number of bytes in the status field of the abnormal segment. If the position of the status field changes from the 4th byte to the 6th byte and the number of bytes changes from 1 to 2, it is recorded as a structurally abnormal segment. All structural differences in the status feedback fields are aggregated, and all segments with more than two structural changes are identified as structurally abnormal. The intersection of the structurally abnormal segments and the status abnormal segments is performed to filter out the page address segments that simultaneously exhibit both status feedback abnormalities and structural feature changes. An abnormal storage structure index table is built according to the page index to form an abnormal storage structure set.

[0042] S502: Based on the abnormal storage structure set, compare the persistence and changes of abnormal process signals, analyze the temporal structure of signal distribution within the storage segment, determine the impact of signal changes on data writing timing, optimize the writing process sequence corresponding to the page alignment parameters, and obtain the timing control parameter set. Continuous statistics and trend recording of status feedback signals for each segment are performed. First, the start and end times of each page's write operation are extracted along the timeline. The time interval between the status field return time and the write start time is calculated. In abnormal segments, it is checked whether this time interval continuously exceeds twice the average of normal segments. For example, if the normal write response latency is 2 milliseconds, and the response latencies for three consecutive pages are 6 milliseconds, 7 milliseconds, and 8 milliseconds respectively, it is recorded as a latency anomaly. When recording the time structure, a response timing distribution diagram for each segment is drawn, and the trajectory of status field values ​​changing over time is marked. If the status value shows a trend of continuous increase or remains unchanged for a long time, it is marked as a high-persistence anomaly segment. In the high-persistence segment, the field transition position is further extracted, and the time difference required for the field to change from 0x00 to 0x03 is analyzed. If the transition occurs within 10 milliseconds after the write is completed, it is considered as the state before the data write is completed. For each state change affecting the data writing logic segment, the corresponding page alignment parameter is extracted. During the write process, this parameter is marked as being set to page boundary alignment. If the parameter is in non-aligned mode and the exception frequency is higher than 75% in the exception segment, it is inferred that non-alignment is highly correlated with exceptions. The page alignment parameter is then adjusted to forced alignment mode, the write operation is executed again, and the exception count is recorded. If the exception frequency drops below 25% after adjustment, this parameter is set to the recommended value for this segment. The execution order of page alignment parameters related to exception segments in all page write operations is reordered, moving alignment parameters originally configured after the data fields to one position before the write command. This sequential adjustment corrects the field's operational stage, establishing a matching structure table between page alignment parameters and the write order. A time-series segment configuration that supports process execution is compiled, forming a time-series control parameter set.

[0043] S503: Based on the timing control parameter set, analyze the adaptability of parameter configuration in each storage segment and timing segment, determine the distribution of parameter switching nodes between abnormal and normal segments, optimize the configuration structure of control parameters in the process, and obtain the write control optimization and adjustment results. Adaptability analysis is performed on the control parameter allocation logic in the write script. First, the timing parameter fields referenced by the write command in each storage segment are extracted. The storage structure is divided into normal segments and abnormal segments according to the address segment. The write latency, page alignment settings, and write retry count in the two segments are compared. If it is found that the probability of anomalies is high when the latency value is 0 or set to the minimum interval in the abnormal segment, it is determined that the parameter configuration is not suitable for the current segment. The correspondence between the current setting and the actual abnormal situation is recorded in the control parameter allocation structure and marked as an item that needs adjustment. Then, the script position where the parameter switching point is located is extracted, and all parameter changes are indexed to the command segment number to determine whether it occurs at the boundary between the normal segment and the abnormal segment. If the parameter switching point is exactly at the boundary between the normal segment and the abnormal segment, the script position where the parameter switching point is located is determined. When a page address jumps from a normal address to an abnormal address, the switching point is considered to be highly relevant to the paragraph structure. This location is marked as a high-sensitivity node. Incremental parameter testing is performed on the paragraph containing the sensitive node, i.e., the write interval value is gradually adjusted and the response status changes are recorded to determine the optimal parameter combination for each sensitive node. In the entire process script, the combination structure is bound to its corresponding storage paragraph, and the parameter binding is updated according to the process order. The control parameter configuration structure table is rearranged, and the control items used by the abnormal segment are given higher priority and written into the configuration segment in advance. The parameter configuration structure is summarized according to the paragraph type to form a configuration master table corresponding to the control items and process segments. The optimization configuration of all control parameter structures in the write script is completed, and the write control optimization adjustment results are output.
