Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
The following describes a method and an apparatus for operating a single chip microcomputer according to an embodiment of the present invention with reference to the drawings.
Fig. 1 is a schematic flow chart of a method for programming a single chip microcomputer according to an embodiment of the present invention.
Before the program code is burnt into the single chip microcomputer, a compiler of an upper computer needs to generate a file recorded with the program code and suffixed with 'Hex' or 'S19'. The Hex file and the S19 are both in a format of a file that can be burned into the single chip microcomputer, and are generally called a Hex file and an S19 file.
On one hand, since the binary code address in the Hex file or the S19 file often needs to be converted to be able to be written, for example: converting the logical address into a physical address, converting the address with the cache into the address without the cache, and the like; on the other hand, a storage (Flash) driver of the lower computer generally needs to write data which conforms to a certain data volume once, and if the data in the Hex file or the S19 file has discontinuous addresses or after the Flash driver writes data for many times, the last remaining data cannot reach the data volume which is written once, the data needs to be filled.
In the prior art, an upper computer executes two steps of address conversion and code filling, and in this case, because a certain difference exists between the address conversion mode and the filling mode by adopting single-chip microcomputers with different chip types, the upper computer matched with the single-chip microcomputers needs to be used for programming, so that the universality of the upper computer is poor.
To solve this problem, an embodiment of the present invention provides a monolithic computer programming method, as shown in fig. 1, the monolithic computer programming method includes the following steps:
The file comprises a first address and data corresponding to the first address. The file format is a Hex file and/or an S19 file. The data mentioned here may be specifically program code to be programmed.
And 102, performing address conversion on the first address related in the file according to an address conversion strategy corresponding to the single chip microcomputer to obtain a second address of the single chip microcomputer.
Specifically, according to an address conversion strategy corresponding to the single chip microcomputer, conversion between a logic address of the file and a physical address of the single chip microcomputer is performed on a first address related to the file, and a second address of the single chip microcomputer is obtained.
And/or according to an address conversion strategy corresponding to the single chip microcomputer, converting the first address related to the file between the address without the cache of the file and the address with the cache of the single chip microcomputer to obtain a second address of the single chip microcomputer.
And 103, according to the data volume of single programming of the single-chip microcomputer, programming data corresponding to the first address in the file at a second address position obtained by converting the first address.
Wherein the data amount includes a byte number of the code.
Specifically, according to the data volume of single-time programming of the single-chip microcomputer, data corresponding to the first address in the file are read in a multiple-time mode.
As a possible situation, when the data volume of the read data is smaller than the data volume of the single-time programming of the single-chip microcomputer, the read data is filled, so that the data volume of the filled data is equal to the data volume of the single-time programming of the single-chip microcomputer; and programming the filled data from the second address position.
As another possible situation, when the data volume of the read data is equal to the data volume of the single programming of the single-chip microcomputer, the read data is programmed from the second address position.
It can be seen that in the prior art, the upper computer is required to be operated manually, the operation steps are complicated, and the Hex file and the S19 file are required to be known to a certain extent by an operator to be filled correctly. In addition, based on single-chip microcomputers of different chip types, the address conversion mode is different, the number of code words which can be written once by Flash drive of different chips is also different, and the upper computer is required to adopt different address conversion modes and code filling modes according to different chips. In the embodiment of the invention, the singlechip executes the two steps of address conversion and code filling, and the upper computer only needs to analyze the Hex file or the S19 file, so that the operation steps of the upper computer are reduced, and the universality of the upper computer is improved.
In this embodiment, a file compiled by an upper computer is obtained, address conversion is performed on a first address related in the file according to an address conversion policy corresponding to a single chip microcomputer to obtain a second address of the single chip microcomputer, and data corresponding to the first address in the file is programmed at a position of the second address obtained by the first address conversion according to a single programming data volume of the single chip microcomputer. Compared with the mode of performing address conversion by the upper computer in the prior art, the method and the device have the advantages that the upper computer has higher universality because the single chip microcomputer performs address conversion according to the corresponding address conversion strategy in the embodiment of the invention, can be suitable for the single chip microcomputers with different chip types, and solve the technical problem of poor universality of the upper computer in the prior art.
For clearly explaining the previous embodiment, this embodiment provides another method for programming a single chip microcomputer, and fig. 2 is a schematic flow chart of the another method for programming a single chip microcomputer according to the embodiment of the present invention.
As shown in fig. 2, the method for programming the single chip microcomputer may include the following steps:
The file comprises a first address and data corresponding to the first address.
In a possible application scenario, the first address in the file may be multiple, and data needs to be written from different multiple first address locations.
Specifically, the preset address conversion policies of the singlechips of different chip types may be different, and each of the singlechips performs conversion between a logical address of the file and a physical address of the singlechip for the first address related to the file according to the respective preset address conversion policies.
For example: in the Hex file, the first address position is 0xC000, and 30 bytes of code in the file need to be written. In the singlechip, the first address is converted into a second address 0x8000 according to a preset address conversion strategy, so that the Flash drive of the singlechip starts from the second address 0x8000 and burns the 30-byte code.
Specifically, the Flash of the single-chip microcomputer drives the data volume written once to be limited, so that the data corresponding to the first address in the file needs to be written many times, and correspondingly, before each writing, the single-chip microcomputer reads a certain amount of data, specifically, the data volume read each time by the single-chip microcomputer is the data volume written once driven by the Flash, so as to meet the writing requirement.
Of course, when the remaining data is insufficient, if the read data amount is smaller than the data amount written by the Flash drive in a single time, the read data needs to be filled so as to be equal to the data amount written by the Flash drive in a single time.
And 204, when the data volume of the data read this time is equal to the data volume of the single-time programming of the single chip microcomputer, programming the data read this time from the second address position.
Specifically, when the data volume of the read data is equal to the data volume of the single-chip microcomputer in one burning, the data does not need to be filled, and the burning step can be directly executed. When the current programming is performed, the read data needs to be sequentially written from the second address position, and the programming pointer is shifted from the second address position to the end position of the current programming.
In a possible application scenario, when the single chip microcomputer is programmed, the whole programming process involves a plurality of second addresses of the single chip microcomputer, and the programming can be performed for many times.
In another possible application scenario, starting from a certain second address position, more data needs to be programmed, and the programming may be performed multiple times.
Based on the above two cases, after each programming, it is necessary to determine whether the entire programming process is finished.
Specifically, if the whole programming process is not finished, there are two cases:
in one case, the first address location of the file is programmed, the next first address location in the file needs to be programmed, and the current second address is updated correspondingly, so that the next programming is performed from the next second address location.
In another case, the first address location of the file is not programmed completely, and programming needs to be continued for the current first address, without programming the next first address location in the file.
When the former case occurs, it is necessary to perform address conversion first and then perform the writing step. In the latter case, the programming step can be performed directly.
Specifically, when the data volume of the read data is smaller than the data volume of the single-time programming of the single-chip microcomputer, two situations exist, one situation is that the file compiled by the upper computer is sent, and after multiple times of programming, the data volume needing to be programmed is insufficient; in another case, the file compiled by the upper computer is not sent completely, so that the data volume required to be programmed is insufficient.
For the first case, padding is needed, while for the second case, only waiting is needed.
Specifically, when the data volume of the read data is smaller than the data volume of the single-time programming of the single-chip microcomputer, the read data is filled, so that the data volume of the filled data is equal to the data volume of the single-time programming of the single-chip microcomputer.
For example: the code with 30 bytes needs to be programmed, the data volume of single programming of the single chip microcomputer is 8 bytes, that is, as the single chip microcomputer of the lower computer, the Flash driver needs to write the code with 8 bytes once, 30% 8 is known to be 6 by calculation, 6 bytes need to be programmed when the programming is performed for the last time, in this case, 2 bytes need to be filled, and the 6 bytes are added to complete 8 bytes for the last programming.
Step 209 waits for the data in the file to be received, and then step 204 is performed.
In this embodiment, a file compiled by an upper computer is obtained, address conversion is performed on a first address related in the file according to an address conversion policy corresponding to a single chip microcomputer to obtain a second address of the single chip microcomputer, and data corresponding to the first address in the file is programmed at a position of the second address obtained by the first address conversion according to a single programming data volume of the single chip microcomputer. Compared with the mode of performing address conversion by the upper computer in the prior art, the method and the device have the advantages that the upper computer has higher universality because the single chip microcomputer performs address conversion according to the corresponding address conversion strategy in the embodiment of the invention, can be suitable for the single chip microcomputers with different chip types, and solve the technical problem of poor universality of the upper computer in the prior art.
As a possible application scenario, the single chip microcomputer related to the single chip microcomputer programming method in the foregoing embodiment may be applied to a vehicle controller of a vehicle and/or an electronic control unit of the vehicle. The vehicle comprises an electric automobile, a fuel automobile and/or a hybrid automobile.
For example: when applied to an electronic control unit of an electric vehicle, the single chip microcomputer can be particularly applied to a motor control electronic control unit, a battery control electronic control unit and the like.
