Detailed Description
The embodiment of the invention provides a method, a device and a storage medium for burning a product serial number, which are used for solving the technical problems of low efficiency and low accuracy of burning the product serial number in the prior art.
In order to better understand the technical solutions of the present invention, the following detailed descriptions of the technical solutions of the present invention are provided with the accompanying drawings and the specific embodiments, and it should be understood that the specific features in the embodiments and the examples of the present invention are the detailed descriptions of the technical solutions of the present invention, and are not limitations of the technical solutions of the present invention, and the technical features in the embodiments and the examples of the present invention may be combined with each other without conflict.
Referring to fig. 1, an embodiment of the invention provides a method for burning a product serial number, and the method includes the following steps.
Step 101: when a serial number burning command of an electronic product is received, a first product serial number with a character type of data acquired from a database is converted into a second product serial number with the same data type as that in a second file containing firmware, and a first file containing the second product serial number and a first burning address is generated.
In order to burn electronic products in batch, a first product serial number corresponding to each electronic device and a first burning address to be burned into the electronic device by the first product serial number can be stored in a database of the burning device, the first product serial number is usually stored in a character type data type in the database, but can also be stored in other data types, and the first burning address is stored in a hexadecimal data type without limitation.
When the burning device receives a serial number burning command of the electronic product, the first product serial number is obtained from the database and is converted into a second product serial number which is the same as the data type in a second file containing the firmware.
For example, the first product serial number of the electronic device 1 in the database is BA120001 (character type), and the data type of the data in the second file containing the firmware is hexadecimal data, and at this time, the first product serial number (BA120001) needs to be converted into the second product serial number (hexadecimal data): 0x 420 x 410 x 310 x 320 x 300 x 300 x 300 x31(0x represents hexadecimal) for the second product serial number to have the same data type as the data in the second file.
If the data type of the first product serial number is the same as that of the data in the second file, conversion is not needed, and the first product serial number is directly used for replacing the second product serial number in a subsequent scheme.
Then, a first file containing the second product serial number and the first burning address can be generated, and the following method can be adopted:
starting from the second product serial number and ending to the high address data of the first burning address, constructing each line of data according to a preset data format to obtain a first file, wherein the method can be realized by adopting the following modes:
sequentially acquiring sub-address data with a first preset number of bytes from the lowest byte to the highest byte, and constructing the first sub-address data and the second product serial number into a row of data before the row of the ending command in the first file according to a preset data format; sequentially constructing a line of data in a first file from the second sub-address data according to a preset data format, and directly obtaining the last sub-address data to obtain the first file; the row containing the sub-address data of the high byte is positioned before the row containing the sub-address data of the low byte.
And when the byte data contained in the last sub-address data is smaller than the first preset value, filling the upper bits of the sub-address data with 0.
For example, with the second product serial number as: 0x 420 x 410 x 310 x 320 x 300 x 300 x 300 x31, the first burnt address is: for example, 0x07a120, the first preset value is 2, and the second preset value is 1.
Starting from the lowest byte (0x20) of the first burned address (0x07a120), sub-address data having 2 bytes is acquired in the direction of the highest byte, with the result that: the first sub-address data is 0xA120, and since 0xA1 has only 1 byte and less than 2 bytes, the upper bits of the last sub-address data are filled with 0, that is, the last sub-address data is 0x 0007.
Since the first burned address (0x07a120) actually includes only 2 sub-address data, the first is 0xA120, and the second is 0x 0007.
Therefore, the first sub-address data 0xA120 and the second product serial number are constructed into a row of data before the row of the ending command in the first file according to a preset data format; and constructing the second sub-address data into a line of data in the first file according to a preset data format to obtain the first file.
The constructed first file content is as follows:
:020000040007F3
:09A120004241313230303030315F
:00000001FF
fig. 2 is a schematic structural diagram of a preset data format according to an embodiment of the present invention.
Presetting a data format, including: the length of the data of the line, the initial address of the line, the type of the data of the line, the data of the line and the checksum of the data of the line.
The line data may be sub-address data other than the first sub-address data, or may be a second product serial number.
When the data type of the line is other sub-address data, the data type of the line is an extended linear address.
And when the data of the line is the second product serial number, the initial address of the line is the second sub-address data, and the data type of the line is the data record.
For example, taking the above-mentioned interior of the first file as an example, in the first file, the first line: the first byte (0x02) represents the data length of the current line; the second, three bytes (0x000 x00) represent the start address of the line data; the fourth word byte (0X04) represents the data type of the line, since the data of the line in the first line is the sub Address data (0X0007), the corresponding data type is identified by '04' and represents the Extended Linear Address Record:); since the sub-address data of the present row includes all the fifth and sixth bytes of the present row data (0X0007) of 2 bytes, it represents an extended linear address; the last byte (i.e. the seventh byte) is the checksum (0xF3) of the data of this line, wherein the algorithm of the checksum is: the checksum is 0x 100-cumulative sum, and the cumulative sum (not counting carry) is the value of all 16-system data before the checksum (0xF3) after byte accumulation without counting carry.
Second line in the first file: the first byte (0x09) represents the data length of the current line; the second, three bytes (0xA 10 x20) represent the present line start address; the fourth byte 0x00 represents the data type of the current row, and since the second product serial number in the second row is the data of the current row, '00' is used to represent the data type of the current row; the fifth to thirteenth bytes represent the present line data (i.e., the second product serial number). Through the sub-address data in the first row and the second row, the address to be written in the second product serial number is 0x 07000000 plus 0xA120, namely the actual address is 0x07a 120; the last byte (i.e., the fourteenth byte) is the checksum of the data in the row, and the checksum is calculated in the same manner as the checksum in the first row.
The last line (00000001FF) of the first file is the line where the end command is located, that is, the data length of the line of the third line is 00, the address is 0000, the data type is 01, and the checksum is the line where the FF end command is located and is used for identifying the end of the second file. The data format used by the line where the end command is located may also be understood as a preset data format, and since the data length of the line in the line where the end command is located is 00, the data of the line is not included in the last line, that is, the data format used by the line where the end command is located includes the following: the length of the data of the line, the address of the data of the line, the type of the data of the line and the checksum of the line.
As another example, the second product serial number is: 0x 420 x 410 x 310 x 320 x 300 x 300 x 300 x31, the first burnt address is: for example, 0x020507a120, the first preset value is 2, and the second preset value is 1.
The sub-address data corresponding to the first burning address (in order from the first one) is: 0xA120, 0x0507, 0x 0002.

After the first file is obtained in the above manner, step 102 may be performed.
Step 102: and merging the first file and a second file containing the firmware to obtain a third file.
Merging the first file with the second file containing the firmware may be accomplished in the following manner:
removing the data of the line where the ending command is located in the third file to obtain intermediate data; and inserting the intermediate data into any line in the second file before the line where the ending command is located to obtain a third file.
For example, the content of the first file is:
:020000040007F3
:09A120004241313230303030315F
:00000001FF
assume that the firmware to be written to the electronic device is the content of the second file, which is (in the following file content, the omitted file content is represented by X for economy):
:020000040000FA
:1000000020EB00208D04000095040000AD020000EC

:00000001FF
the intermediate data (the following data with a line being slid down) after the line of the ending command in the first file is inserted into the second file before the line of the ending command (i.e. the last line), and then the third file is obtained:
:020000040000FA

:00000001FF
it should be noted that the above-mentioned intermediate data may be inserted into any row before the row of the ending command of the second file, and is not illustrated herein for saving space.
Step 103: and burning the third file into a specified storage position of a Micro Control Unit (MCU) of the electronic product.
The designated storage location may be Flash inside the MCU, or other storage space, and is not limited specifically.
