Step S14, executing the starting operation corresponding to the starting instruction, and outputting prompt information; and the prompt information is used for prompting that the 1 model flash memory chip is hit.

Specifically, the starting instruction of the flash memory chip corresponding to the starting code, which is obtained by the computer device, may be a starting instruction of each level of the starting code in the flash memory chip, and when the computer device obtains the starting instruction of each level of the starting code in the flash memory chip, the starting operation corresponding to the starting instruction may be executed, for example, the starting operation of the Bootloader code, the starting operation of the Kernel code, the starting operation of the App code, and the like in each flash memory chip may be sequentially executed.

It should be noted that the following method is only used for explaining the present application and is not used for limiting the present application.

Fig. 2 is a flowchart illustrating a boot method based on a solidified boot code according to another embodiment, where this embodiment relates to a specific process of how a computer device performs a boot operation when the boot information indicates that the solidified boot code is first booted. On the basis of the foregoing embodiment, optionally, as shown in fig. 2, the method further includes:

And step S22, classifying the m sub-operations to obtain a k sub-operation data table.

Specifically, after obtaining m sub-operations, the computer device may classify the m sub-operations, for example, when the m types of flash memory chips are NAND FLASH chips of m types, and d sub-operations corresponding to NAND FLASH chips of d types belonging to SLC in NAND FLASH chips of m types are classified into an SLC class set, e sub-operations corresponding to NAND FLASH chips of e types belonging to MLC are classified into an MLC class set, f sub-operations corresponding to NAND FLASH chips of f types belonging to TLC are classified into a TLC class set, and the like; wherein k class sets such as the MLC class set, and the TLC class set are the k sub-operation data tables, and d + e + f + … … is equal to m.

And step S23, sequentially numbering the m sub-operations and the k sub-operation data tables respectively to obtain numbered m sub-operations and numbered k sub-operation data tables.

Specifically, after obtaining the m sub-operations and the k sub-operation data tables, the computer device may sequentially number the m sub-operations and the k sub-operation data tables, sequentially number the m sub-operations as sub-operation number 1, sub-operation number 2, … …, and sub-operation number m, sequentially number the k sub-operation data tables as table 1, table 2, … …, and table k, and thereby obtain the numbered m sub-operations and the numbered k sub-operation data tables.

TABLE 2

Step S24, determining the numbered m sub-operations as the preset sub-operations, and determining the numbered k sub-operation data tables as the preset sub-operation data tables; wherein m is far greater than 1, and k is an integer greater than 1.

Specifically, after obtaining the numbered m sub-operations and the numbered k sub-operation data tables, the computer device may further determine the numbered m sub-operations as the preset sub-operations, and determine the numbered k sub-operation data tables as the sub-operation data tables, so that the computer device may quickly search and hit when being restarted after being stored.

And step S25, acquiring the starting instruction of the starting code corresponding to the 1 model flash memory chip according to the preset sub-operation data table and the preset sub-operation.

Specifically, after obtaining the preset sub-operation data table and the preset sub-operation, the computer device may directly obtain the operation parameters of 1 type of the flash memory chips, and may also obtain the start instruction of the start code corresponding to the 1 type of the flash memory chips when obtaining the operation parameters of the 1 type of the flash memory chips; the starting instruction of the starting code corresponding to the flash memory chip may be a starting instruction of each level of starting code in the 1 model flash memory chip.

And step S26, storing the preset sub-operation and the preset sub-operation data table into the register, and executing the starting operation corresponding to the starting instruction.

Specifically, when the computer device obtains a start instruction of a start code corresponding to 1 type of flash memory chip, the preset sub-operation and the preset sub-operation data table may be stored in a register, or an identification parameter may be stored in the register, and then the start operation corresponding to the start instruction is executed; the identification parameter may be a bit data, and when the identification parameter is the same as the preset threshold, it may be determined that the preset sub-operation and the preset sub-operation data table stored in the register are valid.

In an actual processing process, the register may be a power-down holding register, a one-time programmable Memory (efuse), a Non-Volatile Memory (NVM), and the preset sub-operation, the preset sub-operation data table, and the identification parameter may be stored in a preset storage unit of the register, where the preset storage unit may be a storage unit with a size of a word.

The preset sub-operation and the preset sub-operation data table can be stored to the high-wbit of the preset storage unit, the identification parameter can be stored to the low-wbit of the preset storage unit, and the preset sub-operation data table can also be stored to the low-wbit of the preset storage unit, and the preset sub-operation data table can be stored to the high-wbit of the preset storage unit.

In this embodiment, when the computer device determines that the obtained start information indicates that the solidified start code is started for the first time, the computer device determines that the preset sub-operation data table and the preset sub-operation are stored after performing the classification processing on the m types of operation parameters of the flash memory chips by packaging the m types of operation parameters of the flash memory chips, performing the classification processing on the m sub-operations obtained after the packaging processing, and numbering the k sub-operation data tables and the m sub-operations obtained after the classification processing, so as to ensure that the computer device can directly obtain the start instruction of the start code corresponding to the flash memory chip by searching the preset sub-operation data table and the preset sub-operation when determining that the solidified start code is not started for the first time, thereby improving the start speed of the flash memory chips of 1 type.

Fig. 3 is a flowchart illustrating a boot method based on a solidified boot code according to another embodiment, where this embodiment relates to a specific process of how a computer device classifies m sub-operations to obtain k sub-operation data tables. On the basis of the above embodiment, optionally, as shown in fig. 3, step S22 may be implemented by the following sub-steps:

and step S221, acquiring the flash memory model of the flash memory chip corresponding to each sub-operation.

Specifically, after obtaining M sub-operations, the computer device may correspondingly obtain a flash memory model of a flash memory chip corresponding to each sub-operation, where the flash memory model may include a storage capacity, a type, a manufacturer, a manufacturing process, and the like of the corresponding flash memory chip, the storage capacity may be 512M, 2G, 8G, 32G, and the like, the type may be SLC, MLC, TLC, and the like, the manufacturer may be Samsung electronics (Samsung), SK maritime (Hynix), Toshiba semiconductor (Toshiba), and the like, and the manufacturing process may be 16 nm, 15 nm, 10 nm, and the like.

Step S222, determining k flash memory model sets belonging to the same flash memory category in the m flash memory models.

Specifically, the flash memory category may be a storage capacity, a type, a manufacturer, a manufacturing process, or the like, and the computer device may store the sameThe flash memory models with the capacity are respectively classified into a flash memory model set, for example, a computer device can store the corresponding t with the storage capacity of 512M in M flash memory models₁Grouping the flash memory model into the 1 st flash memory model set, and storing the corresponding t with the storage capacity of 2G₂Grouping the flash memory models into a 2 nd flash memory model set, … …, corresponding t with a storage capacity of 8G_kThe individual flash model numbers are grouped into a kth set of flash model numbers.

The computer device may also associate t with SLC in m flash memory models₁The type of each flash memory is classified as 1 st flash memory signal set, and the type of the corresponding t is MLC₂Grouping individual flash model into 2 nd flash model set, … …, grouping corresponding t with TLC type_kEach flash memory model is classified into a kth flash memory model set; the computer equipment can also correspond t of Samsung as manufacturer in m flash memory models₁The number of flash memory models is classified as 1 st flash memory model set, and the corresponding t of SK Hynix is the manufacturer₂Each flash model is classified as the 2 nd set of flash models, … …, corresponding t for Toshiba from the manufacturer_kThe individual flash model numbers are grouped into a kth set of flash model numbers.

The computer equipment can also make the corresponding t with the manufacturing process of 16 nanometers in m flash memory models₁Each flash model is classified as the 1 st set of flash models, corresponding to a manufacturing process of 15 nm₂Individual flash model numbers are grouped into the 2 nd flash model set, … …, corresponding t with a manufacturing process of 10 nanometers_kEach flash memory model is classified into a kth flash memory model set; and are not limited herein.

Wherein, the ith flash model set comprises t_iFlash model, i ═ 1, 2, … …, k, t₁+t₂+……+t_k＝m。

Step S223, determining k sub-operation sets corresponding to the k flash memory model sets, and determining the k sub-operation sets as the k sub-operation data tables.

Specifically, when the computer device obtains k flash memory model sets, the k flash memory models can be determined according to the one-to-one correspondence relationship between the flash memory models and the sub-operationsDetermining k sub-operation sets corresponding to the flash memory model set as k sub-operation data tables; wherein, the ith sub-operation data table includes t_iSub-operation, i ═ 1, 2, … …, k, t₁+t₂+……+t_k＝m。

In this embodiment, the computer device first obtains m flash memory models corresponding to m sub-operations, and then further determines k flash memory model sets belonging to the same flash memory category in the m flash memory models, so as to determine k sub-operation sets corresponding to the k flash memory model sets as the k sub-operation data tables, thereby improving flexibility and reliability of determining the k sub-operation data tables by the computer device.

Fig. 4 is a flowchart illustrating a boot method based on a solidified boot code according to another embodiment, which relates to a specific process of how a computer device detects whether a preset sub-operation data table stored in a register and a preset sub-operation are valid. On the basis of the foregoing embodiment, optionally, as shown in fig. 4, the step S12 of detecting whether the data in the register is valid and obtaining the detection result may be implemented by the following sub-steps:

step S121, detecting whether an identification parameter in the register is the same as a preset threshold value, wherein the identification parameter is used for verifying whether the preset sub-operation data table stored in the register and the preset sub-operation are valid.

Specifically, the preset threshold may be a reference value for verifying whether the identification parameter changes; when the computer equipment detects that the identification parameter in the register is the same as the threshold value, the identification parameter is not changed; otherwise, when the computer device detects that the identification parameter in the register is different from the preset threshold value, the identification parameter is changed.

And step S122, when the identification parameter is the same as the preset threshold value, determining that the preset sub-operation data table stored in the register and the preset sub-operation are valid.

Specifically, when the computer device determines that the identification parameter is the same as the preset threshold, it may be determined that the identification parameter has not changed, and the solidified boot code is not a first boot, so that it may be determined that the preset sub-operation data table and the preset sub-operation are stored in the register at this time, and the stored preset sub-operation data table and the preset sub-operation are valid; optionally, the preset threshold may be 0x55 aa.

And S123, outputting the indication information that the data stored in the register is invalid when the identification parameter is different from the preset threshold value.

Specifically, when the computer device determines that the identification parameter is different from the preset threshold, it may be determined that the identification parameter is a default value when the computer device leaves a factory, and at this time, it may be determined that the solidification start code is started for the first time, and the preset sub-operation data table and the preset sub-operation are not stored in the register, so that the indication information that the register is invalid may be output, so that the solidification start code traverses the operation parameters of the m types of flash memory chips to determine the preset sub-operation data table and the preset sub-operation.

In this embodiment, the computer device further determines whether the preset sub-operation and the preset sub-operation data table stored in the register are valid according to the detection result that whether the identification parameter in the register is the same as the preset threshold, so as to ensure the validity and reliability of the register storing the preset sub-operation and the preset sub-operation data table, and improve the functional diversity of the computer device.

Fig. 5 is a flowchart illustrating a starting method based on a solidified boot code according to yet another embodiment, where this embodiment relates to a specific process of how to obtain a next-level application start instruction in the flash memory chip when the computer device determines that the register storage data is invalid. On the basis of the above embodiment, optionally, as shown in fig. 5, after step S12, the method further includes:

and step S31, performing traversal operation on the preset sub-operation data table pre-stored in the solidified starting code to obtain a traversal result of the traversal operation.

Specifically, when the computer device determines that the identification parameter in the register is different from the preset threshold, the data currently stored in the register may be considered invalid, and at this time, the traversal operation may be performed on the preset sub-operation data table pre-stored in the solidified boot code.

The traversing operation on the preset sub-operation data tables may be regarded as sequentially traversing at least one preset sub-operation data table, that is, traversing t included in the 1 st preset sub-operation data table₁The preset sub-operations are sequentially traversed, … …, and/or t is included in the ith preset sub-operation data table_iSequentially traversing the preset sub-operations to obtain a traversal result of the traversal operation; wherein i is 1, 2, … …, k, t₁+t₂+……+t_k＝m。

In the actual processing process, when the computer equipment determines that the solidified starting code is the first-time starting code, the solidified starting code traverses the operation parameters of the m types of flash memory chips to obtain the preset sub-operation data table and the preset sub-operation, and the preset sub-operation data table and the preset sub-operation are stored in a register and also stored in the solidified starting code.

Step S32, when the traversal result of the traversal operation includes the next-level application start instruction in the 1-type flash memory chip, determining that the traversal is successful.

Specifically, after performing traversal operation on at least one preset sub-operation data table, if the obtained traversal result includes a start instruction of a boot code corresponding to 1 type of flash memory chip, for example, when a boot instruction of a Bootloader code is output, it may be indicated that the performed traversal operation is successful.

And step S33, storing the preset sub-operation data table, the preset sub-operation and the identification parameter into the register.

Specifically, after the computer device determines that the traversal operation is successful, the numbered m sub-operations and the numbered k sub-operation data tables can be stored in a high-bit of a preset storage unit of a register, and the identification parameter is stored in a low-bit of the preset storage unit; or storing the identification parameter in the high wbit stored in the preset storage unit, and storing the numbered m sub-operations and the numbered k sub-operation data tables in the low vbit stored in the preset storage unit.

The preset storage unit may be a word-sized storage unit in the register, the numbered m sub-operations may be determined by sequentially numbering m sub-operations obtained by encapsulating operation parameters of m types of flash memory chips, and the numbered k sub-operation data tables may be determined by sequentially numbering k sub-operation data tables obtained by classifying the m sub-operations.

In this embodiment, when determining that the data stored in the register is invalid, the computer device performs traversal operation on a preset sub-operation data table pre-stored in the solidification start code, and determines that traversal success is determined when determining that a traversal result obtained after performing the traversal operation includes a next-level application start instruction in the flash memory chips of 1 model, so as to further improve the flexibility and diversity of the register, and then the computer device stores the preset sub-operation data table, the preset sub-operation and the identification parameter into the register, so that the flash memory chips of 1 model can be quickly hit when the start information that the solidification start code is not started for the first time is subsequently received again, and thus the start speed of the computer device is improved.

Fig. 6 is a flowchart illustrating a boot method based on a solidified boot code according to yet another embodiment, which relates to a specific process of how a computer device determines that a traversal is successful according to a traversal result of a traversal operation. On the basis of the above embodiment, optionally, as shown in fig. 6, step S32 may be implemented by the following sub-steps:

step S321, determining t in the ith sub-operation data table_iThe duration of the sub-operation is determined_iWhether a jth operation parameter corresponding to a jth sub-operation in the sub-operations is valid; j is 1, 2, … …, t_i，i＝1，2，……，k，t₁+t₂+……+t_kK is an integer greater than 1.

Specifically, the computer device may traverse t in the ith sub-operation data table_iT corresponding to sub-operation_iOperating parameters, sequentially judging t_iWhether the 1 st operation parameter is valid, whether the 2 nd operation parameter is valid, … … to the t_iWhether an operational parameter is valid; and judging whether the operation parameters are effective or not comprises judging whether the operation parameters can acquire a starting instruction of the starting code corresponding to the 1 type of flash memory chip or not.

During the actual processing, when the computer device judges t_iWhen the jth operation parameter corresponding to the jth sub-operation in the sub-operations is valid, the process goes to step S322; otherwise, when the computer equipment judges t_iIf the jth operation parameter corresponding to the jth sub-operation in the sub-operations is invalid, the process proceeds to step S323.

And step S322, when the jth operation parameter is valid, determining that the traversal is successful.

Specifically, when the computer device determines t_iWhen the jth operation parameter corresponding to the jth sub-operation in the sub-operations is valid, it indicates that the next-level application starting instruction in the flash memory chip can be obtained according to the jth operation parameter, and at this time, it indicates that the traversal operation is successful.

In the actual process, if the computer device traverses t in the 1 st sub-operation data table₁T corresponding to sub-operation₁An operating parameter and determines t₁When the 1 st operation parameter is valid, it can also be said that the traversal operation is successful.

Step S323, when the jth operation parameter is invalid, determining that j < t_iIf so, the value of j is incremented by 1, and the process returns to step S321 to determine t_iWhether a jth operation parameter corresponding to a jth sub-operation in the sub-operations is valid; if the jth operating parameter is invalid, and determining j-t_iThen, the process proceeds to step S324.

Specifically, when the computer device determines that the jth operation parameter is invalid, it indicates that the next-level application start instruction in the flash memory chip cannot be obtained according to the jth operation parameter, and it indicates that the traversal operation is not successful, and at this time, the value of j may be determined again after adding 1.

In the actual process, if the computer device traverses t in the 1 st sub-operation data table₁T corresponding to sub-operation₁An operating parameter and determines t₁When the 1 st operation parameter is invalid, the judgment of t can be continued₁Whether the 2 nd operation parameter is valid or not is judged, and when the 2 nd operation parameter is invalid, the judgment of t is continued₁Whether the 3 rd of the operational parameters is valid, … …, and so on.

If t is₁One of the operation parameters is judged to be valid, and the traversal operation is successful and can also be stopped; if t is₁All the operation parameters are judged to be invalid, and the t in the 2 nd sub-operation data table can be processed₂T corresponding to sub-operation₂The individual operating parameters are traversed in sequence.

Step S324, when t is reached_iT corresponding to sub-operation_iIf all the operation parameters are invalid and i is determined to be less than k, the value of i is added with 1, and the step S321 is entered to judge t_iWhether a jth operation parameter corresponding to a jth sub-operation in the sub-operations is valid; if t is_iT corresponding to sub-operation_iIf all the operation parameters are invalid, and if it is determined that i is k, the process proceeds to step S325.

Specifically, when the computer judges t_iT corresponding to sub-operation_iWhen all the operating parameters are invalid, the description is based on t_iAny one of the operation parameters cannot acquire a next-level application starting instruction in the flash memory chip, and at this time, traversal operation can be performed on a next sub-operation data table of the current sub-operation data table; for example, the computer determines t in the 1 st sub-operation data table₁T corresponding to sub-operation₁When all the operation parameters are invalid, the 2 nd sub-operation can be continuously judgedT in data sheet₂T corresponding to sub-operation₂And judging whether the operation parameters have effective operation parameters or not, … …, and so on, and determining that the traversal is successful when the operation parameters corresponding to one sub-operation in the k preset sub-operation data tables are effective.

And step S325, outputting reminding information, wherein the reminding information is used for reminding the starting failure.

Specifically, after traversing k preset sub-operation data tables, the computer device determines that no valid operation parameter exists, at this time, it indicates that the stored data in the register is invalid, the preset sub-operation data table pre-stored in the solidified start code is also invalid, and at this time, the computer device cannot be normally used for hitting 1 operation parameter of 1 model of flash memory chip, so that a prompt message of this start failure is output.

In this embodiment, the computer device sequentially performs traversal operation on m operation parameters corresponding to the k sub-operation data tables to determine whether an effective operation parameter exists, and the computer device can determine that traversal is successful if only one effective operation parameter exists in the m operation parameters, and output a prompt message of this start failure when all the m operation parameters are invalid, so that flexibility and intelligence of the computer device are improved.

Fig. 7 is a flowchart illustrating a starting method based on a solidified boot code according to another embodiment, where this embodiment relates to a specific process of how a computer device determines whether a next-level application start instruction in the 1 model flash memory chip can be acquired based on the operating parameter. On the basis of the foregoing embodiment, optionally, as shown in fig. 7, as to determine whether the operation parameter is valid and includes a start instruction based on whether the operation parameter can acquire the start code corresponding to the 1 model flash memory chip in step S321, the following sub-steps may be implemented:

step S3211, the starting data of the next-level application is correspondingly obtained according to the operation parameters.

Specifically, the starting process of the computer device may include a BOOTROM, a boot loader (Bootloader), a real-time operating system program (Kernel), an application program (App), and the like, where — represents a next-level starting object, a firmware package composed of the Bootloader, the Kernel, the App, and the like is written in each flash memory chip, and header files of the Bootloader, the Kernel, and the App respectively include preset check parameters, and the preset check parameters may include preset check bits and preset check values.

Therefore, when the computer device traverses one preset sub-operation in the k preset sub-operation data tables, it may be further determined whether an operation parameter of the flash memory chip corresponding to the preset sub-operation is valid, that is, the computer may correspondingly obtain the boot data of the next stage in the 1 model flash memory chips according to the operation parameter, for example, when the next stage is a Bootloader, the boot data that the computer device correspondingly obtains according to the operation parameter is a Bootloader code.

Step S3212, the startup data is checked according to a preset check parameter, and it is determined whether the checked startup data is consistent with the startup data corresponding to the next-level application startup instruction.

Specifically, the preset check parameter may be a preset check digit and a preset check value carried by the boot data corresponding to the next-stage application boot instruction, for example, when the next-stage application boot instruction is a boot instruction of a Bootloader code, the computer device may check the boot data obtained corresponding to the operation parameter according to the preset check parameter in the Bootloader code, and then further determine whether the checked boot data is the same as the boot data corresponding to the boot instruction of the Bootloader code, where the check result indicates that the checked boot data is correct when the check result is the same, and the check result indicates that the checked boot data is incorrect when the check result is different.

In the actual processing process, the preset check value in the Bootloader code may be a magic check value, a crc check value, and the like, and when the checked boot data is the same as the boot data corresponding to the boot instruction of the Bootloader code, it indicates that the checked boot data passes through the magic and crc check, and at this time, it indicates that the operation parameter is valid; otherwise, when the verified boot data is different from the boot data corresponding to the boot instruction of the Bootloader code, it indicates that the verified boot data does not pass at least one of the verifications such as magic and crc, and at this time, it indicates that the operation parameter is invalid.

Step S3213, if the operation parameters are consistent, determining that a next-level application starting instruction in the 1 model flash memory chip can be acquired based on the operation parameters.

Specifically, the computer device determines that the verified boot data is the same as the boot data corresponding to the boot instruction of the Bootloader code, and may determine that the verified boot data passes verification such as magic and crc of the Bootloader code, thereby indicating that the operation parameter is valid, and the computer device may obtain the boot instruction of the Bootloader code according to the operation parameter.

Step S3214, if not, determining that the next-level application start instruction in the 1 model flash memory chip cannot be acquired based on the operation parameters.

Specifically, when the computer device determines that the verified boot data is different from the boot data corresponding to the boot instruction of the Bootloader code, it may be determined that the verified boot data does not pass at least one of the verifications such as the magic and the crc of the Bootloader code, thereby indicating that the operation parameter is invalid, and the computer device may not obtain the boot instruction of the Bootloader code according to the operation parameter.

In this embodiment, when the computer device obtains the start data of the next-level application according to the operation parameter, the computer device checks the preset check parameter, and further determines whether the checked start parameter is the same as the start data corresponding to the start instruction of the next-level application, so as to determine whether the start instruction of the next-level application in the 1 model flash memory chips can be obtained according to the operation parameter, thereby improving the reliability and flexibility of obtaining the start instruction of the next-level application of the 1 model flash memory chips by the computer device, and also improving the functional diversity of the electronic device.
