In one embodiment, step 103 comprises: after the operating system finishes starting on the hardware simulation platform, executing a copy instruction; and copying the file to be updated to a target folder under the operating system through a copy instruction.
Wherein the copy instruction is an instruction to run on the linux system, and the copy instruction may be a dd command. The dd command of the linux system is used to read, convert, and output data. dd commands may read data from a standard input or file, convert the data according to a specified format, and output to a file, device, or standard output. And copying the file to be updated to a target folder under the linux system through a copy instruction.

The target file format supported by the hardware simulation platform is in a current configuration relationship with the EMU platform. Specifically, the configuration of the EMU platform is obtained so as to obtain the target file format supported by the hardware simulation platform. If the target file format supported by the current configuration of the EMU platform is binary, converting the file to be updated into a file in the binary format; and if the target file format supported by the current configuration of the EMU platform asks for the hex format, converting the file to be updated into the file with the hex format.

Assume that the target folder described in the above embodiment is a dev/mem/myko folder under a linux operating system, the format of the target file is a hex format, the file to be updated is a file, and the file to be updated after the format conversion is a file _ hex file.
When the addresses of the storage space for storing the files to be updated are determined to be 0x60000000 to 0x90000000, the file _ hex files are stored into the storage space corresponding to the addresses of the storage space, and then the file _ hex in the storage space corresponding to the addresses of the storage space is loaded into the dev/mem/myko folder through a dd command or through a preset application service.
The method comprises the steps of firstly determining a storage space address used for storing a file to be updated in a memory of a chip to be tested, and then loading the file to be updated into a storage space corresponding to the storage space address through a back door interface provided by a hardware simulation platform, so that the file to be updated is loaded into the storage space address preset by the chip to be tested through the back door interface provided under the condition that the hardware simulation platform does not have a peripheral drive and a network environment, and thus, after an operating system is started on the hardware simulation platform, the file to be updated in the storage space is copied into a target folder under the operating system. Namely, in the embodiment of the application, the application program to be updated is copied to the operating system running on the hardware simulation platform under the condition that the hardware simulation platform does not have a peripheral driver and a network environment.
In an embodiment, the step of determining the address of the storage space for storing the file to be updated includes: acquiring the number of memory blocks of a memory; utilizing the script file to segment the file to be updated so as to obtain the segmented files with the same number as the storage blocks; and determining the address of a storage space for storing the corresponding divided file in the corresponding number of storage blocks of the memory. The number of the storage blocks refers to the number of blocks of the memory, and the files to be updated are divided into the divided files with the number equal to the number of the blocks of the memory, so that the files to be updated can be read from each block simultaneously when being read, the address is convenient to fetch, and the reading speed is high.
In an embodiment, the step of determining the address of the storage space for storing the file to be updated includes: acquiring the number of memory blocks of a memory and a reading mode of the memory configured by a hardware simulation platform; determining whether the file to be updated needs to be divided or not according to the number of the storage blocks and the reading mode, and determining the number of targets needing to be divided when the file needs to be divided; the method comprises the steps that a script file is used for dividing a file to be updated to obtain divided files with a target number, wherein the target number is smaller than or equal to the number of storage blocks; and determining the storage space address for storing the corresponding divided file in the storage blocks of the corresponding target number of the storage. In this embodiment, whether the file to be updated needs to be divided is determined according to the reading mode and the number of the storage blocks, so that the file to be updated is divided during the division.
In one embodiment, after the split file is obtained, an object file format supported by a hardware simulation platform is obtained, and the split file is converted by using a script file, so that the file format of the split file is the object file format. Therefore, the hardware simulation platform can accurately load the partitioned files.
In an embodiment, when the file to be updated is divided into a target number of divided files, before the step of executing the copy instruction, the method further includes: merging the divided files in the storage blocks of the storage corresponding to the target number to obtain a file to be updated; the step of executing the copy instruction is then performed.
Fig. 3 is another schematic flow chart of the file processing method according to the embodiment of the present application. The file processing method is also applied to the electronic equipment, and comprises the following steps.
201, obtaining the number of memory blocks of the memory of the chip to be tested and the reading mode of the memory configured by the hardware simulation platform.
The number of the memory blocks of the memory may be two, four, or the like, that is, the number of the memory blocks may be two or four. The reading mode of the memory configured by the hardware simulation platform can be a first reading mode, a second reading mode, a third reading mode and the like. The first reading mode may be parallel reading, and in the reading mode, the file content of each memory block in the memory may be read in parallel. The second reading mode is similar to that of a flash memory. The third reading mode can be other reading modes and the like.
And 202, determining whether the file to be updated needs to be divided or not according to the number of the memory blocks and the reading mode, and determining the target number which needs to be divided when the file to be updated needs to be divided, wherein the file to be updated comprises an updated file corresponding to an application program to be updated which runs in an operating system, and the target number is less than or equal to the number of the memory blocks.
And determining whether the file to be updated needs to be divided according to the reading mode of the memory. For example, if the reading mode is the first reading mode, determining that the file to be updated needs to be divided; and if the reading mode is the second reading mode, determining that the file to be updated does not need to be divided, and the like.
When the division is needed, the target number needed to be divided is determined according to the number of the memory blocks. For example, when the number of memory blocks is four, it is determined that the number of objects to be divided is four. In some embodiments, the number of targets to be divided may also be set to be smaller than the number of memory blocks, which may be done by changing the reading mode. For example, the number of memory blocks is four, and the target setting is determined to be three, two, and so on.
And 203, determining the address of the storage space for storing the corresponding divided file in the storage blocks corresponding to the target number of the storage.
And planning corresponding storage space addresses in the storage for the target number of storage blocks, wherein the storage space addresses are used for storing the corresponding split files.
And 204, segmenting the file to be updated by utilizing the script file to obtain a target number of segmented files.
The script file is used for segmenting the file to be updated to obtain a target number of segmented files. For example, if the target number is four, the divided files may be divided into divided file 1, divided file 2, divided file 3, and divided file 4, respectively.
205, obtaining a target file format supported by the hardware simulation platform, and converting the split file by using the script file, so that the file format of the split file is the target file format.
The target file format may be a hex format, a binary format, and the like. For example, the target file format is a hex format, and each split file is format-converted by using a script file to obtain split files in the hex format, such as file _ hex1, file _ hex2, file _ hex3, and file _ hex4, respectively.
The execution sequence of step 203 and steps 204 to 205 is not particularly limited. Step 203 and steps 204 to 205 may be performed in parallel or may be performed in series. When executing serially, steps 204 to 205 may be executed first, and then step 203 may be executed.
And 206, loading a preset script file of the hardware simulation platform, and loading the split file into a storage space corresponding to the corresponding storage space address through a back door interface provided by the hardware simulation platform in the preset script file.
In this step, the step is consistent with the step of loading the file to be updated into the storage space corresponding to the corresponding storage space address through the backdoor interface provided by the hardware simulation platform. Please refer to the corresponding description above. What is different, in this step, each different partition file needs to be loaded into the storage space corresponding to the storage space address of the corresponding storage block through the back door interface. For example, memory address 1, which is planned in memory block1, is used to store file _ hex1, memory address 2, which is planned in memory block2, is used to store file _ hex2, memory address 3, which is planned in memory block3, is used to store file _ hex3, and memory address 4, which is planned in memory block4, is used to store file _ hex 4.
In addition, it should be noted that the preset script file and the script file mentioned above are not the same file.
207, after the kernel of the operating system is started, a preset application is started and run, and the preset application is created and compiled in the operating system before the operating system is started.
And 208, detecting whether the storage space has file contents or not through a preset application.
Since the storage space corresponding to the storage space address is specially used for storing the file to be updated, when the storage space is detected to have the file content, the file content is the file to be updated loaded in a backdoor manner.
Whether the storage space has the storage content is detected by the preset application, if so, step 209 is executed, and if not, step 208 is executed next.
And 209, executing a copy instruction through a preset application, and copying the file to be updated to a target folder under the operating system through the copy instruction.
Wherein the copy instruction comprises a dd command of the linux system. Please refer to the corresponding description above, which is not repeated herein. In one embodiment, before the step of executing the copy instruction, the method further comprises: and merging the split files in the storage space of the storage block corresponding to the memory to obtain the file to be updated.
The embodiment determines whether the file to be updated needs to be divided according to the number of the memory blocks of the memory and the reading mode of the memory configured by the hardware simulation platform, and determines the target number to be divided when the file needs to be divided so as to divide the file to be updated according to the target number, so that the addressing speed and the reading speed are improved when the divided file is read. And after the content of the operating system is started, the preset application is operated, so that the file to be updated is automatically copied to the target folder under the operating system through the preset application, and the file processing speed is improved by automatically executing the operation. In addition, files to be updated are stored in a memory of the chip to be updated through a back door interface of the hardware simulation platform, after the operating system is started, the corresponding test to be updated is read from the memory, and the application program to be updated is copied to the operating system running on the hardware simulation platform under the condition that the hardware simulation platform does not have a peripheral drive and a network environment.

The number of the storage blocks in the memory is 4, and the storage blocks are respectively block1, block2, block3 and block4, the determined dividing number of the files to be updated is a target number, and the target number is 4. Memory space addresses 1, 2, 3 and 4 are respectively planned in blocks 1, 2, 3 and 4 of the memory. Dividing the file to be updated into four parts, and performing format conversion to convert the file into four divided files with the hex format, namely file _ hex1, file _ hex2, file _ hex3 and file _ hex 4.
