Description

Technical Field

[0001] This invention relates to the field of driver technology, and in particular to a connector firmware fragmentation upgrade method and system. Background Technology

[0002] The field of driver technology involves the interface between computer hardware and the operating system. Through driver software, the operating system can effectively communicate and control hardware devices. Core aspects of this field include the development and optimization of hardware device drivers, driver compatibility with the operating system, and driver updates and maintenance. Drivers play a crucial role in system startup, device control, and data transmission. Traditional connector firmware fragmentation upgrade methods involve fragmenting the firmware to adapt to the firmware upgrade requirements of different hardware platforms. In traditional methods, firmware upgrades are achieved by completely downloading and writing the firmware to ensure the device's firmware version is updated. This method typically uses a step-by-step download and installation approach, dividing the firmware into several data blocks for transmission. Each data block is installed and updated sequentially in the device until the entire firmware is updated. While this method can achieve firmware upgrades, it suffers from low transmission efficiency when handling large-capacity firmware or when network bandwidth is limited, and may lead to errors or failures during the upgrade process.

[0003] Traditional connector firmware upgrade methods focus on dividing the entire image into fixed-size data blocks for simple sequential transmission. This approach ignores the alignment differences between firmware logical fragments and physical sector boundaries in memory, causing frequent physical page-skipping erase / write operations during data writing. This significantly increases the wear and tear on the storage medium and prolongs instruction execution waiting time. The fixed transmission frequency is difficult to adapt to real-time load fluctuations in the hardware link, easily causing communication bus congestion and buffer overflow risks. It lacks in-depth monitoring of write address continuity and hardware verification status. Address jumps during the upgrade process can cause verification errors, leading to frequent firmware update task failures or system malfunctions. If an atomic synchronization verification mechanism is lacking after the image is written, logical conflicts can easily occur during version rollback and overwrite processes. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and to propose a connector firmware segmentation upgrade method and system.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a connector firmware segmentation upgrade method, comprising the following steps: S1: Collect the fragment byte length, offset position and check bit information of the connector firmware, and perform logical alignment verification with the sectors stored in the hardware Flash, identify the overlap space between the fragment boundary and the physical page, and output the fragment alignment mapping feature set of the firmware storage space. S2: Extract the overlapping space parameters from the firmware storage space fragment alignment mapping feature set, and based on the overlapping space parameters, determine the corresponding instruction flow cycle and DMA channel occupancy rate of the underlying driver on the physical bus. Through the coupling calculation of instruction execution frequency and physical link delay, lock the load boundary of the hardware transmission link and obtain the interface bandwidth instruction delay evaluation result. S3: Based on the interface bandwidth instruction delay evaluation result, retrieve the real-time idle level of the connector on-chip cache and the number of physical interrupt requests suspended at the port, perform a correlation comparison between the cache drop ratio and the interrupt priority, adjust the enqueue order of the fragments at the physical layer and inject clock phase correction parameters, and generate a fragment transmission sequence reorganization and sorting scheduling instruction set. S4: Call the fragmented transmission sequence reorganization and sorting scheduling instruction set, track the physical address increment continuity of the Flash write pointer and the hardware redundancy check register status, calculate the linear superposition of the physical address jump amplitude after being assigned a dimensionally normalized weight coefficient and the hardware checksum offset, and output the connector firmware matching degree adjustment and fragmented upgrade sequence.

[0007] As a further aspect of the present invention, the step of obtaining the firmware storage space fragment alignment mapping feature set specifically includes: S111: Obtain the raw data packet of the connector firmware, lock the binary image stream of the connector firmware, parse the segment descriptor in the firmware header, determine the total number of fragments and the sector address space of each segment, extract the physical offset and CRC cyclic redundancy check code in the global address space, and output the fragment basic attribute set. S112: Based on the fragmentation basic attribute set, perform a modulo operation of the fragmentation byte length on the physical erase unit of the Flash memory, locate the alignment extreme value of the fragmentation start address in the physical page, identify the storage distribution remainder when the fragmentation crosses the physical page boundary, and obtain the fragmentation layout characteristic parameters; S113: Based on the fragmentation layout characteristic parameters and the storage gap between the serial transmission protocol and the verification sequence of the physical layer bus, calculate the physical link addressing logic between non-contiguous storage blocks and output the firmware storage space fragmentation alignment mapping feature set.

[0008] As a further aspect of the present invention, the step of obtaining the interface bandwidth command delay evaluation result specifically includes: S211: Based on the firmware storage space fragment alignment mapping feature set, the physical pulse signal frequency of the driver layer communication interface in the current crystal oscillator cycle is detected in real time, the physical bus time window occupied by the effective signal packet is extracted, the absolute deviation of the pulse signal frequency from the reference frequency is quantified and a square mapping operation is performed to generate local frequency offset energy features, and the local frequency offset energy features in the full sampling interval are accumulated, fused and normalized based on the number of measured signal packets. The normalization result is scaled and modulated in the physical time domain using the crystal oscillator cycle, and the modulation product is square rooted to smooth the data dimensions. The link jitter amplitude characterizing the transmission instability is extracted, and the channel response mapping value group is obtained. S212: Call the channel response mapping value group, record the hard delay from the host control terminal sending the Write instruction to the connector controller returning the ACK signal, analyze the throughput efficiency of the internal cache of the Flash controller under the differentiated alignment characteristics, and obtain the channel real-time load sequence; S213: Based on the real-time load sequence of the channel, extract the electromagnetic interference tolerance and signal impedance fluctuation of the physical layer bus during the continuous write cycle, and combine the corresponding instruction timeout retransmission frequency and hardware interrupt response loss rate to identify the physical link congestion suppression index and obtain the interface bandwidth instruction delay evaluation result.

[0009] As a further aspect of the present invention, the step of obtaining the fragmented transmission sequence reassembly and sorting scheduling instruction set specifically comprises: S311: Based on the interface bandwidth instruction delay evaluation result, retrieve the number of real-time hardware concurrent processing tasks of the connector physical interface, and read the overflow level of the on-chip FIFO queue allocated to the programming task to establish the task scheduling pressure coefficient. S312: Call the task scheduling pressure coefficient, compare it logically with the hardware preset response priority, perform spatial rearrangement for the fragment enqueue logic of the fragment alignment mapping feature set of the firmware storage space, analyze the address mapping deviation after rearrangement, and obtain the fragment reorganization optimization sequence. S313: Based on the fragment reassembly optimization sequence, the execution time of the ISR of the underlying driver and the clock interrupt frequency are integrated to set the hardware layer scheduling weight corresponding to the fragment, determine the physical address jump step and write strength, and generate a fragment sending sequence reassembly sorting scheduling instruction set.

[0010] As a further aspect of the present invention, the steps for obtaining the connector firmware matching degree adjustment and segment upgrade sequence are specifically as follows: S411: Call the fragment sending sequence reorganization and sorting scheduling instruction set, monitor the stability of the write current and programming cycle of the fragment at the Flash physical target address, calculate the span increment between adjacent fragment physical write addresses, compare the offset difference between the current write pointer and the preset continuous address space, and obtain the address continuity deviation value. S412: Based on the address continuity deviation value, synchronously read the real-time status of the hardware ECC register, analyze the verification consistency between the real-time solidified data in the physical medium and the original logic of the firmware package, perform hardware compensation calculation on the address jump and verification deviation, and obtain the matching adjustment amount of the writing process. S413: Invoke the matching adjustment amount of the writing process, and in conjunction with the Busy / Ready feedback signal of the storage controller, perform low-level reconstruction of the mapping logic between the Flash physical writing path and the internal Page management unit, optimize the instruction pipeline, and obtain the connector firmware matching degree adjustment and fragment upgrade sequence.

[0011] As a further aspect of the present invention, the method further includes step S5: S5: Based on the connector firmware matching degree adjustment and fragment upgrade sequence, poll the storage metadata status of multiple sector erase and write cycles, determine the convergence trajectory of firmware physical coverage by atomic logical mapping of the boot loading unit version identifier bit and physical image integrity flag, determine the effective status of the upgrade task, and output the convergence result of the version update synchronization status task. The convergence results of the version update synchronization status task include version synchronization identifier, package integrity percentage, and upgrade convergence status.

[0012] As a further aspect of the present invention, the steps for obtaining the convergence result of the version update synchronization state task are as follows: S511: Based on the connector firmware matching degree adjustment and segment upgrade sequence, collect the physical distribution bitmap of the segments in the Flash storage unit, construct the firmware image physical vector, identify the binary structure similarity between the written data blocks and the original image file, analyze the address overlap growth slope of the writing progress, and generate the upgrade progress overlap amplitude sequence. S512: Call the upgrade progress overlap amplitude sequence, extract the difference vector of overlap amplitude within the continuous erase and write cycle, determine whether the physical write action has entered the tail clearing stage based on the polarity of the difference, and combine the preset storage convergence preset threshold to determine the stabilization state of sector writing and obtain the upgrade execution fusion stable trend value. S513: Based on the upgraded execution fusion stability trend value, trigger the atomic switching instruction of the firmware version descriptor, and combine the consistency judgment flag of physical fragment verification to verify whether the new version firmware completely replaces the old version image at the physical layer, and output the convergence result of the version update synchronization status task.

[0013] The connector firmware fragment upgrade system is used to execute the above-described connector firmware fragment upgrade method. The system includes: The firmware fragment structure detection module obtains the fragment byte length, offset position and check bit of the connector firmware, locks the binary bit offset and byte width of each physical fragment of the connector firmware, performs logical alignment verification with the sector step size reference of the hardware Flash memory, and establishes a firmware storage space fragment alignment mapping feature set by identifying the overlapping space between the fragment boundary and the physical page address. The transmission channel load analysis module, based on the firmware storage space fragment alignment mapping feature set, detects the instruction flow cycle and DMA channel occupancy rate of the underlying driver unit on the physical bus. By coupling the calculation of instruction execution frequency and link delay, it locks the physical load boundary of the hardware transmission link and obtains the interface bandwidth instruction delay evaluation result. The firmware upgrade scheduling strategy generation module, based on the interface bandwidth instruction delay evaluation result, retrieves the real-time idle level of the connector on-chip RAM cache and the number of physical interrupt requests pending at the port, performs a correlation comparison between the cache drop ratio and the interrupt priority, adjusts the enqueue order of the fragments at the physical layer and injects clock phase correction parameters to obtain the fragment transmission sequence reorganization and sorting scheduling instruction set. The fragmented write verification module, based on the fragmented sending sequence reorganization and sorting scheduling instruction set, tracks the physical address increment continuity of the Flash write pointer and the state of the hardware redundancy check register. By assigning corresponding weight coefficients to the physical address jump amplitude and the hardware check offset, the module analyzes the matching trend of continuous physical block record points and obtains the connector firmware matching degree adjustment and fragmented upgrade sequence. The upgrade status determination module polls the storage metadata status of multiple sector erase / write cycles based on the connector firmware matching degree adjustment and fragment upgrade sequence. By atomically mapping the bootloader unit version identifier bit and the physical image integrity flag, it determines the convergence trajectory of the firmware physical overlay and obtains the convergence result of the version update synchronization status task.

[0014] Compared with the prior art, the advantages and positive effects of the present invention are as follows: In this invention, alignment mapping features are constructed by identifying the overlap space between fragment boundaries and physical page addresses, effectively eliminating write latency caused by cross-page erase operations. Load boundaries are determined by combining instruction flow cycles and link jitter amplitude, dynamically adjusting bus transmission bandwidth utilization to ensure communication link stability and significantly reduce instruction timeout retransmission frequency. Real-time monitoring of cache idle levels and injection of clock phase correction parameters optimize fragment enqueue order and physical scheduling weights, improving instruction pipeline execution efficiency and enhancing hardware concurrency. The continuity of write pointers is tracked and hardware compensation calculations are performed to correct address jumps and checksum offset deviations, achieving high-precision aligned writing of firmware data. Atomic logic mapping is used to determine convergence trajectories, accelerating version synchronization and ensuring image update integrity, reducing data verification conflicts and enhancing firmware deployment security, significantly shortening upgrade cycles and improving system compatibility.

[0018] For examples, please refer to Figure 1 This invention provides a technical solution, a method for upgrading connector firmware in segments, comprising the following steps: S1: Collect the fragment byte length, offset position and check bit information of the connector firmware, perform logical alignment verification with the step size reference of the hardware Flash storage sector, identify the overlapping space between the fragment boundary and the physical page address, and output the fragment alignment mapping feature set of the firmware storage space.

[0019] The firmware storage space fragment alignment mapping feature set includes byte length feature value, offset position index, check bit feature vector, and sector comparison deviation. The interface bandwidth instruction delay evaluation result includes interface bandwidth utilization, instruction delay weighted value, and channel congestion index. The fragment transmission sequence reassembly and sorting scheduling instruction set includes reassembly sequence index, displacement deviation parameter, response time correction value, and scheduling priority weight.

The version update synchronization status task convergence result includes version synchronization identifier, packet integrity percentage, and upgrade convergence status.

[0020] Please see Figure 2The specific steps for obtaining the firmware storage space fragment alignment mapping feature set are as follows: S111: Obtain the raw data packet of the connector firmware, lock the binary image stream of the connector firmware, parse the segment descriptor in the firmware header, determine the total number of fragments and the sector address space of each segment, extract the physical offset and CRC cyclic redundancy check code in the global address space, and output the fragment basic attribute set. After inputting the basic attribute set of the fragments, an alignment extreme value operation is performed on the physical architecture of the Flash memory. Flash hardware specifications are called, setting the physical erase unit block size to 128KB and the physical page size to 4KB. A modulo operation is performed on the fragment byte length against 4096 to locate the alignment extreme value of the fragment's starting address within the physical page. For a 13312-byte fragment, if the modulo operation result is non-zero, the remaining storage distribution when the fragment crosses the physical page boundary is identified. All 12 fragments are traversed, recording the offset of each fragment relative to the starting position of the physical page. When a fragment starts at an offset of 2048 bytes from the physical page, after the remaining 2048 bytes fill the current page, the fragment still has 11264 bytes remaining (13312-2048=11264). These 11264 bytes will continue to span and occupy multiple subsequent physical pages, contrary to the incorrect description in the text that "the remaining 2048 bytes overflow to adjacent physical pages." By calculating the distance between each shard and the physical page boundary, potential write latency points due to physical structure limitations are determined. This process does not rely on software prediction, but rather uses the integer division relationship between the hardware page size and the shard length to determine the actual space occupied by the shard in the physical storage array, providing physical offset input for subsequent bandwidth assessment.

[0021] S112: Based on the basic attribute set of the fragment, perform a modulo operation of the fragment byte length on the physical erase unit of the Flash memory, locate the alignment extreme value of the fragment start address in the physical page, identify the storage distribution remainder when the fragment crosses the physical page boundary, and obtain the fragment layout characteristic parameters. After inputting the basic attribute set of the fragments, alignment extreme value calculations are performed on the Flash memory physical architecture. Flash hardware specifications are called, setting the physical erase unit block size to 128KB and the physical page size to 4KB. A modulo operation is performed on the fragment byte length against 4096 to locate the alignment extreme value of the fragment's starting address within the physical page. For a 13312-byte fragment, if the modulo operation result is non-zero, the remaining storage distribution term when the fragment crosses the physical page boundary is identified. All 12 fragments are traversed, and the offset displacement of each fragment relative to the starting position of the physical page is recorded. When a fragment starts at an offset of 2048 bytes from the physical page, the remaining 2048 bytes overflow to adjacent physical pages, forming an unaligned distribution state. The offset distance parameter is recorded, generating fragment layout characteristic parameters. These parameters describe the distribution pattern of firmware data in the physical storage medium, especially marking fragmented areas generated by cross-page storage. By calculating the distance between each shard and the physical page boundary, potential write latency points due to physical structure limitations are determined. This process does not rely on software prediction, but rather uses the integer division relationship between the hardware page size and the shard length to determine the actual space occupied by the shard in the physical storage array, providing physical offset input for subsequent bandwidth assessment.

[0022] S113: Based on the fragmentation layout characteristic parameters, and according to the serial transmission protocol of the physical layer bus and the storage gap of the verification sequence, calculate the physical link addressing logic between non-contiguous storage blocks, and output the firmware storage space fragmentation alignment mapping feature set. The fragmentation layout characteristic parameters are combined with hardware link characteristics for logical calculation. The physical layer bus serial transmission protocol is read, the maximum length of a single burst transmission is identified as 256 bytes, and the storage gap of the verification sequence in the storage medium is locked. The gap value is set to 16 bytes for storing error correction codes. Based on the serial transmission protocol and storage gap, the physical link addressing logic between non-contiguous storage blocks is calculated. When fragmentation is split into multiple non-contiguous blocks due to alignment requirements, the address jump distance between blocks is calculated, such as jumping from address 0x00002000 to 0x00003010. The logical delay generated by the jump instruction is recorded. The addressing logic and spatial mapping topology are integrated to output the firmware storage space fragmentation alignment mapping feature set. This feature set quantifies and records the data storage location and addressing path on the physical chip, including bus transmission overhead, address jump time, and bandwidth occupied by the verification gap. By simulating the serial read process of the physical layer bus, the extra addressing cycles caused by non-contiguous storage are calculated and converted into the corresponding number of clock cycles. The resulting feature set converts the logical fragmentation structure into a mapping matrix that includes physical constraints, enabling the upper-layer scheduler to perceive the storage characteristics of the underlying Flash memory.

[0023] Please see Figure 3 The specific steps for obtaining the interface bandwidth command latency evaluation results are as follows: S211: Based on the firmware storage space fragment alignment mapping feature set, the physical pulse signal frequency of the driver layer communication interface within the current crystal oscillator cycle is detected in real time, and the physical bus time window occupied by the effective signal packet is extracted using the formula: ; Calculate the link jitter amplitude and obtain the channel response mapping value group; in, Represents the amplitude of link jitter. Representing the The frequency of each pulse signal Represents the reference frequency. Represents the number of measurement signal packets. Represents the crystal oscillator period; The firmware storage space fragment alignment mapping feature set is used as the logical boundary for data input. The underlying communication reference is locked by real-time detection of the physical pulse signal frequency of the driver layer communication interface within the current crystal oscillator cycle. For data acquisition environment setup, the probes of the high-frequency logic analyzer are connected to the clock output pin and data bus pin of the connector main controller, with a sampling rate of 2.5GHz to ensure complete capture of nanosecond-level signal glitches. The crystal oscillator cycle is determined by reading the prescaler value from the system clock configuration register. In this embodiment, the crystal oscillator operating frequency is 25MHz, corresponding to the cycle... The sampling window is set to 40 nanoseconds, and the physical bus time window occupied by the valid signal packet is determined by the level transition interval between the start bit and the stop bit. The sampling window width is set to 1.5 microseconds. To quantitatively describe the stability of physical links, the following formula is used: Calculate the link jitter amplitude. During this calculation, the reference frequency is used. Instead of a fixed theoretical value, it is determined by the average frequency of 1000 standard communication packets pre-collected in a shielded room environment. In this embodiment, its value of 25.0001MHz was obtained through offline calibration. The number of signal packets measured... The statistical confidence level requirement is set at 1000. The frequency of each pulse signal By counting the clock edges within each signal packet at equal intervals, and considering the impact of external electromagnetic fluctuations on the connector interface during actual operation, a data sequence containing 1000 samples was acquired through real-time monitoring. The frequency... The frequency fluctuates normally between 24.9992MHz and 25.0008MHz, and the obtained reference frequency... (Value is 25.0001MHz), Number of measurement samples (Value 1000), Crystal Oscillator Period (Value 40 nanoseconds) and 1000 pulse frequency sampling points are substituted into the above formula. By accumulating the squares of the differences between each sampling point and the reference frequency, and combining this with the time base ratio, the final result, the link jitter amplitude, is calculated. The result is 0.0068 nanoseconds, which is within the range of excellent link performance (0 to 0.01 nanoseconds), indicating that the current channel response has extremely high synchronization consistency. Based on this, the channel response mapping value group is obtained. Table 1: Actual Measured Data of Channel Response and Link Jitter ; As shown in Table 1, by quantifying the frequency offset under different electromagnetic interference intensities, the formula's ability to capture minute link fluctuations was verified. The advantage of the formula lies in its ability to effectively convert minute frequency-domain offsets into time-domain jitter indicators by introducing the product of the crystal oscillator period and frequency dispersion, thus more intuitively reflecting the synchronization risk of the bus during high-speed data transmission. Experimental data show that when the link jitter amplitude decreases from 0.0361 nanoseconds to 0.0068 nanoseconds, the bit error rate of the interface decreases from... Reduce to The following results significantly improve the accuracy of the channel response mapping values, demonstrating that the current physical link is capable of supporting high-bandwidth upgrades.

[0024] S212: Call the channel response mapping value group, record the hard delay from the host control terminal sending the Write command to the connector controller returning the ACK signal, analyze the throughput efficiency of the Flash controller's internal cache under the differentiated alignment characteristics, and obtain the channel real-time load sequence; After the channel response mapping value group is obtained, the instruction execution hard latency recording stage begins. A kernel timer is started to record the time from when the host controller issues the 0x02 code Write instruction to when the connector controller returns an acknowledgment signal. The hard latency data is calculated from the difference; in standard alignment mode, the latency is 85 microseconds. The throughput efficiency of the controller's internal cache is analyzed under differentiated alignment characteristics. For unaligned fragments with an offset of 512 bytes, a read-to-write mechanism is triggered, causing the cache hit rate to drop from 95% to 72%. Sampling is performed on 500 consecutive write operations, and the hard latency and cache efficiency data are fused over time to generate a real-time channel load sequence. This load sequence reflects the data throughput pressure of the interface under different fragment alignment states. By decomposing the hard latency, the additional internal shifting time generated when the Flash controller processes unaligned data is identified. When a fragment spans a physical page, the controller must first read the entire page of data, modify the corresponding bytes, and then rewrite, resulting in a significant increase in instruction latency. The real-time load sequence marks the latency points on the timeline, forming a quantitative view of channel occupancy.

[0025] S213: Based on the real-time load sequence of the channel, extract the electromagnetic interference tolerance and signal impedance fluctuation of the physical layer bus during the continuous write cycle. Combine the corresponding instruction timeout retransmission frequency and hardware interrupt response loss rate to identify the physical link congestion suppression index and obtain the interface bandwidth instruction delay evaluation result. After acquiring the real-time load sequence of the channel, the electromagnetic interference tolerance and signal impedance fluctuation data within the continuous write cycle of the physical bus are extracted. The electromagnetic interference tolerance threshold is set to -45dBm, and the ambient interference value monitored by the spectrum analyzer is -52dBm. The signal impedance fluctuates from 50 ohms to 65 ohms during fragmented cross-page writing, with a fluctuation rate of 30%. Combined with the instruction timeout retransmission frequency and the hardware interrupt response loss rate of 0.01%, a multi-factor weighted algorithm is used to identify the physical link congestion suppression index. When the retransmission frequency is less than 5 times and the interrupt loss rate is less than 0.05%, the congestion suppression index is 0.92. The parameters are integrated to obtain the interface bandwidth instruction delay evaluation result. This evaluation result integrates the electrical characteristics of the physical link and the execution efficiency of the instruction layer, including not only the static link status but also the dynamic task conflict situation. By introducing the congestion suppression index, the root cause of the bus bandwidth limitation can be identified, namely, whether it is retransmission caused by electrical noise or interrupt loss caused by excessive controller load.

[0026] Please see Figure 4 The specific steps for obtaining the fragmented transmission sequence reorganization and sorting scheduling instruction set are as follows: S311: Based on the interface bandwidth instruction delay evaluation results, retrieve the number of real-time hardware concurrent processing tasks of the connector physical interface, and read the overflow level of the on-chip FIFO queue allocated to the programming task to establish the task scheduling pressure coefficient. The system retrieves the number of concurrent hardware processing tasks at the connector's physical interface in real time, reads the task counter in the control register, and finds four concurrent tasks, each occupying a different percentage of the bus bandwidth. It also synchronously reads the overflow level of the on-chip FIFO queue for the programming tasks; the FIFO depth is 128 bytes, with 112 bytes already occupied, representing a water level percentage of 87.5%. Based on the 120-microsecond latency feedback from the interface bandwidth instruction latency evaluation results, a task scheduling pressure coefficient is established. The task number weight is set to 0.4, and the water level weight is set to 0.6; a weighted sum is then used to obtain the pressure coefficient. To ensure a reasonable weighted sum of the task number and water level percentage, the task number is first normalized by dividing by the system's maximum supported task number, converting the task number to the same dimension as the water level percentage. When the pressure coefficient exceeds the threshold of 0.8, the hardware is determined to be in a high-load state. This pressure coefficient reflects the urgency of hardware resources in processing the burning task. The higher the value, the greater the risk of FIFO overflow. By monitoring the water level in real time, the imbalance between the instruction issuance speed and the hardware processing speed can be detected. When the pressure coefficient remains high, it indicates that there is a blockage in the current instruction execution chain, and subsequent sequence rearrangement is needed to reduce the instantaneous bandwidth requirement.

[0027] S312: Call the task scheduling pressure coefficient, compare it logically with the hardware preset response priority, perform space rearrangement for the fragment enqueue logic in the firmware storage space fragment alignment mapping feature set, analyze the address mapping deviation after rearrangement, and obtain the fragment reorganization optimization sequence. The task scheduling pressure coefficient is applied, and the burning task is set to priority level 2. The pressure coefficient of 0.85 exceeds the 0.75 warning line, triggering dynamic priority adjustment. The burning task is then promoted to level 1. For the fragment queuing logic within the fragment alignment mapping feature set, spatial rearrangement is performed. Based on the contribution of fragment alignment overhead, fragments with lower alignment overhead are prioritized for queuing. The address mapping deviation after rearrangement is analyzed, and the Euclidean distance between the rearranged sequence and the physical contiguous addresses is calculated. The original address sequence [1, 2, 3] is rearranged to [1, 3, 2], with a deviation value of 1.414. A fragment reassembly optimization sequence is generated. The core of the reassembly optimization sequence lies in utilizing the natural alignment characteristics of Flash physical page writing to aggregate fragments that do not require "read-modify-write". By calculating the address offset after rearrangement, it is ensured that although the logical order has changed, the physical mapping relationship remains accurate. The deviation parameter is used to evaluate the impact of this rearrangement on addressing time, balancing alignment gain and jump overhead.

[0028] S313: Based on the fragment reassembly optimization sequence, the ISR execution time and clock interrupt frequency of the underlying driver are integrated to set the hardware layer scheduling weight corresponding to the fragment, determine the physical address jump step and write strength, and generate a fragment transmission sequence reassembly sorting scheduling instruction set. Based on the fragment reassembly optimization sequence, the actual execution time of the interrupt service routine is 4.5 microseconds, the clock interrupt frequency is 1000Hz, the fragment hardware layer scheduling weight is set, the weight of the first fragment in the reassembly sequence is assigned to 0.95, the physical address jump step is determined, and the span from the end of the current fragment to the start address of the next fragment is 2048 bytes. A flow limit is applied based on a write intensity of 512KB per second. The scheduling weight, step size, and write intensity are encapsulated into binary control words to generate a fragment transmission sequence reassembly sorting scheduling instruction set. This instruction set directly acts on the DMA controller and bus arbiter to ensure that the burned data enters the FIFO at a controlled frequency. Through dynamic allocation of scheduling weights, high-priority fragments receive more bus cycles, thereby reducing instruction latency. The final generated instruction sequence contains complete jump logic and timestamp constraints, achieving efficient burning under high hardware load conditions.

[0029] Please see Figure 5 The specific steps for obtaining the connector firmware matching degree adjustment and segment upgrade sequence are as follows: S411: Invokes the fragment send sequence reorganization and sorting scheduling instruction set, monitors the write current stability and programming cycle of fragments at the Flash physical target address, calculates the span increment between adjacent fragment physical write addresses, compares the offset difference between the current write pointer and the preset continuous address space, using the formula: ; Obtain the address continuity deviation value; in, This represents the address continuity deviation value. The current value representing the current write current. The current value representing the write current of the previous cycle. This represents the write current value of the k-th sample. This represents the average write current, where n is the total number of samples. The system invokes a fragmented send sequence reordering scheduling instruction set. By connecting a sampling resistor in series on the Flash power line and using a high-precision current monitoring chip, it monitors the stability of the write current and programming cycle at the physical target address of the Flash. The write current stability directly reflects the physical load balance of the memory chip during the programming process. To accurately measure the degree of matching between address span and electrical characteristics, the following formula is used: To obtain the address continuity deviation value, during this operation, the current value of the current being written is... The current value is acquired by monitoring the chip at the median time of the current slice write operation. In this embodiment, the measured value is 15.12 mA, which is the current value of the write current in the previous cycle. The current value is provided by the average current value of the previous successful programming cycle cached by the system. In this embodiment, the value obtained by substituting the aforementioned parameters is 14.95 mA, and the total number of samples is... The value is set to 100 to smooth out instantaneous current noise using statistical methods, representing the average write current. and the write current value of each sample In this embodiment, 100 high-frequency samples were collected within the current programming window. These 100 samples were distributed between 14.85 mA and 15.35 mA, and the average value was calculated. The current is 15.10 mA. (Value is 15.12 mA), previous current (Value is 14.95 mA), average value (Value is 15.10 mA) and 100 sample points are substituted into the above formula. By calculating the ratio of the current current step to the overall sampling standard deviation, the final address continuity deviation value is obtained. It is 0.82; Table 2: Correlation between write current and address deviation: ; Table 2 shows the deviation calculation results under different programming loads. The advantage of the formula is that by normalizing the dynamic standard deviation of current fluctuations, it can filter out the inherent static noise of the hardware and accurately identify drastic changes in electrical characteristics caused by abnormal address spans. Experimental data shows that when the address continuity deviation value... When controlled below 1.0, the inconsistency of Flash sector programming fatigue (PE_Cycle) is reduced by 18%, which significantly improves the physical security of fragmented writing. This result shows that the offset between the current write pointer and the preset address space is within a benign fluctuation range, without triggering a large-scale logical refactoring.

[0030] S412: Based on the address continuity deviation value, synchronously read the real-time status of the hardware ECC register, analyze the verification consistency between the real-time solidified data in the physical medium and the original logic of the firmware package, perform hardware compensation calculations on address transitions and verification deviations, and obtain the matching adjustment amount of the writing process. Based on the address continuity deviation value, when the deviation value is greater than 1.5, the error counter records the number of bit flips per kilobyte. The consistency between the physically stored data and the original logic check is analyzed. A 1-bit deviation is found when comparing the original checksum 0xABCD with the real-time checksum 0xABCC. Hardware compensation calculations are performed, adjusting the charge pump programming voltage from 12V to 12.2V to enhance signal write strength. The parameters are packaged as a write process matching adjustment amount. This adjustment amount acts on the underlying drive circuit of the storage controller, fine-tuning the width and amplitude of the programming pulse to offset signal attenuation caused by physical span. The hardware consistency verification process covers the entire process from ECC error correction to block-level verification. Through quantitative analysis of the verification deviation, the required charge compensation amount is calculated, thereby physically repairing signal noise interference caused by misaligned storage and ensuring the level quality of the stored data.

[0031] S413: Call the matching adjustment amount of the write process, and in conjunction with the Busy / Ready feedback signal of the storage controller, reconstruct the underlying mapping logic between the Flash physical write path and the internal Page management unit, optimize the instruction pipeline, and obtain the connector firmware matching degree adjustment and fragment upgrade sequence. When the write process matches the adjustment amount, and the feedback signal duration exceeds a 500-microsecond threshold, the page management unit's mapping logic is adjusted. Data is rerouted to a low-wear physical free page, the instruction pipeline is optimized, the next fragment data is prefetched into the cache, waiting cycles are reduced, and the matching adjustment amount, feedback signal, and refactoring mapping logic are integrated to generate a connector firmware matching degree adjustment and fragment upgrade sequence. The sequence includes fragment data and dynamic write parameters. Path reconstruction is achieved by modifying the mapping table from logical block address to physical block address within the controller. When the Busy signal indicates that the page programming time is too long, it is determined that the current physical page has performance degradation, and the adjustment amount triggers address redirection logic. The final generated upgrade sequence ensures that the distribution of firmware data within Flash not only meets alignment requirements but also dynamically avoids physical defects, improving the long-term reliability of firmware updates.

[0032] Please see Figure 6 The specific steps for obtaining the convergence result of the version update synchronization status task are as follows: S511: Based on connector firmware matching degree adjustment and fragment upgrade sequence, collect the physical distribution bitmap of fragments in Flash storage unit, construct firmware image physical vector, identify the binary structure similarity between written data blocks and original image file, analyze the address overlap growth slope of writing progress, and generate upgrade progress overlap amplitude sequence. Based on the fragmented upgrade sequence, the controller page address mapping table is read, and a physical distribution bitmap of the fragments within the storage unit is acquired. The bitmap is presented as a binary array, with a value of 1 marking a written block and a value of 0 marking an area to be written. A similarity algorithm is used to identify the consistency of the written block's binary structure with the original image file. A sliding window of 256 bytes is set, and the Hamming distance of the binary sequence is calculated. The slope of the address overlap growth during the write progress is analyzed. Within a 5-second observation period, the overlap area increases from 10% to 85%, with a slope of 15% / s, generating an upgrade progress overlap amplitude sequence. This sequence records the dynamic process of the firmware image's transformation from a logical file to physical media. Similarity analysis is used to verify the integrity of the written data. By comparing the written physical bitmap with the expected mapping distribution map, the degree of overlap between the two is calculated. The slope parameter reflects the actual utilization rate of the write bandwidth. When the slope is consistently high, it indicates that the upgrade process is progressing at a uniform speed without any abnormal interruptions.

[0033] S512: Call the upgrade progress overlap amplitude sequence, extract the difference vector of overlap amplitude within the continuous erase and write cycle, determine whether the physical write action has entered the tail clearing stage based on the polarity of the difference, combine the preset storage convergence preset threshold, determine the stabilization state of sector writing, and obtain the upgrade execution fusion stable trend value. The upgrade progress overlap sequence is invoked. In period 10, the overlap is 98.5%, and in period 11, it's 99.2%, with a difference of 0.7%. The polarity of this difference determines the physical write operation stage. When the difference vector remains below 0.1% and has a positive polarity, it indicates that data writing is nearing completion. Combined with a 99.9% storage convergence preset threshold, the sector write stability is assessed. When the overlap exceeds 99.9% for three consecutive sampling periods, the system is considered to have entered the fusion and stabilization stage, generating an upgrade execution fusion and stabilization trend value. This trend value serves as the core indicator for upgrade completion, reflecting the saturation of the physical write progress. By detecting the polarity of the difference vector, the start of the tail erase and verification stages can be accurately identified. When the difference vector approaches zero, it means the address space has been completely covered by the new firmware data, and no new write operations are generated. This convergence judgment mechanism effectively prevents premature upgrade interruption due to write latency, ensuring complete image solidification.

[0034] S513: Based on the upgrade execution fusion stability trend value, trigger the atomic switching instruction of the firmware version descriptor, and combine the consistency judgment flag of physical fragment verification to verify whether the new version firmware has completely replaced the old version image at the physical layer, and output the convergence result of the version update synchronization status task. Based on the stable trend value of the upgrade execution convergence, when it reaches 1.0, an atomic switching instruction for the firmware version descriptor is triggered. The instruction is executed within the protected sector, and the running version identifier is changed from V1.0 to V2.0. Combined with the physical fragment verification consistency judgment flag, a global CRC32 check is initiated to perform a secondary verification on the image space. The check value matches the original value in the firmware header, confirming that the new version firmware has completely replaced the old version image at the physical layer. After the reset self-test status code is checked, the version update synchronization status task convergence result is output. The task convergence result includes the firmware integrity flag, physical page alignment status, and version switching success status word. In the final stage, the atomic switching is verified by reading the protected page where the new version descriptor is located. If the self-test code shows that the hardware initialization is successful and the CRC check passes, the upgrade task is considered closed-loop. This result is fed back to the upper-layer management end through the bus as the final status update basis for firmware lifecycle management.

[0035] The connector firmware fragment upgrade system is used to execute the above-mentioned connector firmware fragment upgrade method. The system includes: The firmware fragment structure detection module obtains the fragment byte length, offset position and check bit of the connector firmware, locks the binary bit offset and byte width of each physical fragment of the connector firmware, performs logical alignment verification with the sector step size reference of the hardware Flash memory, and establishes a firmware storage space fragment alignment mapping feature set by identifying the overlapping space between the fragment boundary and the physical page address. The transmission channel load analysis module, based on the firmware storage space fragment alignment mapping feature set, detects the instruction flow cycle and DMA channel occupancy rate of the underlying driver unit on the physical bus. By coupling the calculation of instruction execution frequency and link delay, it locks the physical load boundary of the hardware transmission link and obtains the interface bandwidth instruction delay evaluation result. The firmware upgrade scheduling strategy generation module, based on the interface bandwidth instruction delay evaluation results, retrieves the real-time free water level of the connector on-chip RAM cache and the number of physical interrupt requests pending at the port, performs a correlation comparison between the cache drop ratio and the interrupt priority, adjusts the enqueue order of the fragments at the physical layer and injects clock phase correction parameters to obtain the fragment transmission sequence reorganization and sorting scheduling instruction set. The fragmented write verification module, based on the fragmented sending sequence reorganization and sorting scheduling instruction set, tracks the continuous increment of the physical address of the Flash write pointer and the state of the hardware redundancy check register. By assigning corresponding weight coefficients to the physical address jump amplitude and the hardware checksum offset, the module analyzes the matching trend of continuous physical block record points and obtains the connector firmware matching degree adjustment and fragmented upgrade sequence. The upgrade status determination module polls the storage metadata status of multiple sector erase / write cycles based on connector firmware matching degree adjustment and fragment upgrade sequence. By atomically mapping the bootloader unit version identifier bit and physical image integrity flag, it determines the convergence trajectory of firmware physical overlay and obtains the convergence result of the version update synchronization status task.
