Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
An embodiment of the present invention provides a method for upgrading system software, as shown in fig. 1, including:
and S10, starting a bootstrap program.
And S20, judging whether the system software is upgraded or not.
The system software includes a software development kit and an application program. The software development kit is generated by compiling software development kit code in a corresponding software development kit file (stack. The application program is compiled from application program code in a corresponding application program file (app.
It is understood that the code of the system software is divided into software development kit code and application program code; the software development kit code generates a software development kit file, and the application program code generates an application program file; the software development kit file and the application file are both binary files.
It should be noted that the Software Development Kit (SDK) includes a Protocol stack (Protocol stack) and a Software management unit (Soft Device Manager). The Application programs include an Application Soft Device (APP) and an Application Peripheral driver (APP-peripherals).
A software tool development kit is a collection of development tools used in building application software. Typically, a software vendor encapsulates some basic program functions and provides API (application programming Interface) functions to the outside through a software tool development kit.
And the API function is a preset function of the software tool development kit and is used for providing an interface for accessing the program function of the software tool development kit for the host program based on the software tool development kit.
And S30, if not, upgrading is not carried out.
And S40, if yes, judging to upgrade the software development kit and/or upgrade the application program.
Thus, three situations may occur, the first one only upgrades the software development kit, and the application program is not upgraded; the second type only upgrades the application program, and the software development kit does not upgrade; the third requires upgrading both the software development kit and the application.
And S50, if the software development kit is upgraded, the bootstrap program writes the upgraded software development kit file into the first address space in the memory.
The memory can be Flash.
And S60, generating an API function address list according to the physical addresses distributed by the API functions in the upgraded software development kit file. That is, the API function address list stores the physical address information of each API function in the first address space.
And S70, if the application program is upgraded, the bootstrap program writes the upgraded application program file into the second address space in the memory.
The application program calls the API function in the software development kit file using the API function address list.
It can be understood that, for the first case where only the software development kit is upgraded and the application program is not upgraded, the application program file originally written in the second address space in the memory is not changed, and the bootstrap program only writes the upgraded software development kit file in the first address space in the memory, and then deletes the originally written software development kit file.
Aiming at the situation that the software development kit is not upgraded for the second type of application program only, the software development kit file originally written into the first address space in the memory is not changed, and the bootstrap program only writes the upgraded application program file into the second address space in the memory and deletes the originally written application program file.
For the third situation of upgrading both the software development kit and the application software, the software development kit file originally written into the first address space in the memory and the application program file written into the second address space are both deleted, the bootstrap program writes the upgraded software development kit file into the first address space in the memory again, and writes the upgraded application program file into the second address space.
For example, the address space occupied by the boot program in the memory is 0x 00000000-0 x00003 fff; if the software development kit and the application software need to be upgraded, the bootstrap program writes the upgraded software development kit file into a first address space (0x00004000 to 0x00022AB0) in the memory, and writes the upgraded application program file into a second address space (0x00028000 to 0x0002A000) in the memory.
The software development kit is large in size, but is rarely upgraded, and the software development kit file can be solidified in the memory at one time, so that the system reliability is enhanced; the file of the application program is smaller, and the space of a second address in the required memory is relatively small, so that a Micro Control Unit (MCU) with low memory can be selected to reduce the cost; based on the method, the software development kit file can be solidified in the memory, and only a small application program file is frequently transmitted, so that the program guide process time is shortened, the power consumption is reduced, and the user experience can be effectively improved.
The embodiment of the invention provides a method for upgrading system software, wherein codes of the system software are divided into software development kit codes and application program codes, the software development kit codes are compiled to generate a software kit, and the application program codes are compiled to generate an application program. Therefore, when the system software is upgraded, the bootstrap program can independently upgrade the software development kit or independently upgrade the application program or simultaneously upgrade the software development kit and the application software by judging the upgrade software development kit and/or upgrading the application program; if the software development kit is upgraded, the bootstrap program writes the upgraded software development kit file into a first address space in the memory, and if the application program is upgraded, the bootstrap program writes the upgraded application program file into a second address space in the memory. By flexibly selecting the files to be upgraded, the cost can be reduced, the power consumption and the writing time can be reduced, the efficient upgrade of system software can be realized, and the user experience can be improved.
Optionally, in the above S50, the method for writing the upgraded software development kit file into the first address space in the memory by the bootstrap program includes:
the boot program allocates the API functions in the upgraded software development kit file to different physical addresses of the first address space in the memory using a scatter load technique.
It should be noted that the scatter loading technique refers to putting each compiled function at a specific physical address in the memory.
For example, the boot program uses scatter-load techniques to allocate each API function in the upgraded software development kit file to a different physical address in the first address space (0x 00004000-0 x00022AB0) in memory.
Optionally, as shown in fig. 2, before the step S10, the method for upgrading system software further includes:
and S1, dividing the upgraded system software code into upgraded software development kit code and upgraded application program code.
And S2, generating an upgraded software development kit file from the upgraded software development kit code.
And S3, generating an upgraded application program code file from the upgraded application program code.
And S4, encrypting the upgraded software development kit file to generate an upgraded software development kit encrypted file.
It can be understood that the upgraded software development kit file is encrypted, so that the risk of stealing the software development kit code can be avoided, and the software development kit code can be protected.
Optionally, the S4 includes:
and encrypting the upgraded software development kit file by using an advanced encryption standard algorithm to generate an upgraded software development kit encrypted file.
The Advanced Encryption Standard (AES) is to encrypt a plaintext P (i.e., an upgraded software development kit file) by using an AES Encryption function E and a key K, and obtain a ciphertext C (i.e., an upgraded software development kit encrypted file) according to C ═ E (K, P).
Optionally, as shown in fig. 3, after the step S4, the method for upgrading system software further includes:
and S5, encrypting the upgraded application program code file to generate an upgraded application program code encrypted file.
It should be noted that, compared to the software development kit, the application program needs to be frequently upgraded, and therefore, when the upgraded application program code file is encrypted, on the basis of implementing the protection of the application program code, an algorithm with a lower level than the software development kit code encryption algorithm may be selected, for example, only simple verification is required, so as to improve the efficiency of loading and writing the application program file.
Optionally, as shown in fig. 4, after the above S40 and before S50, the method for upgrading system software further includes:
and S41, the bootstrap program decrypts the upgraded software development kit encrypted file to obtain an upgraded software development kit file.
It can be understood that the software development kit is encrypted by using the advanced encryption standard algorithm, and the encrypted text C (i.e., the upgraded software development kit encrypted file) is decrypted by using the AES decryption function D and the key K, and the plaintext P (i.e., the upgraded software development kit file) is obtained according to P ═ D (K, C).
Optionally, as shown in fig. 5, after the above S40 and before S70, the method for upgrading system software further includes:
and S61, the bootstrap program decrypts the upgraded application program code encrypted file to obtain an upgraded application program code file.
It should be noted that, for encrypting and decrypting The file corresponding to The whole system software, encrypting The software development kit file and The application program file at different levels respectively, and upgrading The software development kit code file or upgrading The application program code file separately according to The upgrading requirement, so that only The software development kit code encrypted file needs to be decrypted or only The application program code encrypted file needs to be decrypted, thereby improving The security, shortening The OTA (Over The Air) delay and improving The user experience.
