Detailed Description
In order to make the technical solutions and advantages of the embodiments of the present invention clearer, 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 some embodiments of the present invention, but not all embodiments.
In the field of optical communication, an embedded controller mainly uses an MCU. The MCU is still one of the most important controllers at present due to its low cost and high reliability. Programs in the MCU generally comprise application programs and bootstrap programs; the application program is used for realizing the corresponding functional task of the optical module, and the functions of the product in the field of optical communication are continuously perfected and enriched in the life cycle, so that the application program needs to be upgraded and updated for many times; the bootstrap program is used to boot and load the application program to realize online upgrade. In the related art, the MCU provides a set of boot-based programs to load the application programs, and update the upgrade package according to a specified protocol (e.g., 1K-xmodem, IIC, etc.), thereby completing the upgrade of the application programs. The upgrading process of the application program specifically comprises the following steps: when online upgrade operation occurs, the method jumps to a bootstrap program, the bootstrap program completes transmission, verification and storage of an upgrade package, and guides and loads a new application program. Meanwhile, in the whole process of upgrading the application program, the service function of the optical module is not affected.
The application program can realize online upgrade through the guiding and loading functions of the guiding program; the boot program generally runs in a code storage area of the embedded controller, when the boot program runs, the running code of the boot program cannot be erased, when the boot program is forcibly erased, the whole program in the MCU is abnormal and crashes, and when the whole program in the MCU is abnormal and crashes, the service function of the optical module is influenced, and service interruption occurs.
Therefore, in the related art, when upgrading the boot program, the boot program cannot be directly realized through online upgrade, and the embedded chip must be returned to the factory and realized by using a special tool. The limitation of the upgrading mode of the bootstrap program causes inconvenience for users and increases the maintenance cost of the chip.
The embodiment of the invention provides a method for upgrading a bootstrap program on line based on the background, and the method can be compatible with the original conventional bootstrap application program on-line upgrading system. The updating and upgrading of the bootstrap program are realized by adding partial functions to the application program. Meanwhile, the whole upgrading process is completely compatible with the original upgrading system, and the whole upgrading process can not cause interruption and exit of any optical service.
In each embodiment of the invention, the upgrading file of the bootstrap program and the upgrading file of the application program are imported into different partitions of the chip memory, and the function of reading and writing the chip memory is added in the application program. After the application program is upgraded by using the original bootstrap program, the upgraded application program can execute a corresponding bootstrap program upgrade command, namely, the upgrade file of the bootstrap program read from the third partition is written into the first partition for storing the bootstrap program operation file, and then, the bootstrap program operated by the chip is the upgrade file of the bootstrap program read from the first partition.
The embodiment of the invention provides a method for upgrading a bootstrap program, and fig. 1 is a schematic flow chart illustrating the implementation of the method for upgrading the bootstrap program according to the embodiment of the invention. As shown in fig. 1, the method comprises the steps of:
step 101: acquiring a first upgrade package, wherein the first upgrade package comprises an upgrade file of an application program and an upgrade file of a bootstrap program;
step 102: respectively storing the upgrade files of the application program and the boot program to a second partition and a third partition of a memory on a chip; the memory includes a first partition, a second partition, and a third partition; the first partition is used for storing an operation file of a bootstrap program; the second partition is used for storing an upgrade file of the application program; the third partition is used for storing an upgrade file of the bootstrap program;
step 103: upgrading the application program based on the upgrading file of the application program by using the original file of the bootstrap program stored in the first partition;
step 104: running the upgraded application program; and reading the upgrade file of the bootstrap program from the third partition by the upgraded application program, and replacing the original file of the bootstrap program in the first partition by using the read upgrade file of the bootstrap program.
The bootstrap program upgrading method provided by the embodiment of the invention can be applied to embedded chips, such as MCU (microprogrammed control Unit).
In step 101, here, the upgrade file of the application program may be a compiled binary (english may be expressed as BIN) file corresponding to the application program to be upgraded (or the upgraded application program); the upgrade file of the boot program may be a compiled binary file corresponding to the boot program to be upgraded (or the upgraded boot program).
In practical application, the manner of acquiring the first data packet may be to receive the first data packet sent by the electronic device that has established a connection relationship with the embedded chip. Here, the electronic device may be an upper computer, and the description will be given by taking the upper computer as an example.
In practical application, before step 101, the upper computer needs to combine the upgrade file of the application program and the upgrade file of the boot program according to a specific requirement to form a first upgrade package. A special requirement here may be that the structure of the upgrade file of the application matches the structure of the second partition in the subsequent chip memory, and the structure of the upgrade file of the boot program matches the structure of the third partition in the subsequent chip memory.
Before step 102, a partition operation needs to be performed on the memory on the chip, so that the upgrade file of the application program and the upgrade file of the boot program can be stored in different partitions in the memory of the chip.
Based on this, in an embodiment, the method further comprises:
acquiring first configuration information; the first configuration information is used to modify a partition of the on-chip memory;
and performing partition operation on the memory according to the first configuration information.
In practical application, the chip memory may be an erasable memory such as Flash on an embedded chip.
In practical application, the manner of acquiring the first configuration information may be to receive the first configuration information sent by the upper computer. In practice, the memory may be divided into a plurality of partitions, but the total capacity of the plurality of partitions cannot exceed the total capacity of the memory.
In one embodiment, as shown in fig. 2, the memory is divided into three partitions, i.e., a first partition, a second partition and a third partition, according to the first configuration information. And the first partition is used for storing the running file of the bootstrap program; the second partition is used for storing an upgrade file of an application program; the third partition is used to store an upgrade file of the boot program.
In actual application, after the partitioning operation is performed, the original file of the boot program is stored in the first partition for subsequent use, where the original file of the boot program may be a compiled binary file corresponding to the original application program.
In step 102, during actual application, the original boot program writes the upgrade file of the application program into the second partition, and writes the upgrade file of the boot program into the third partition. Here, the original boot program may be understood as a boot program before upgrading, and a compiled binary file corresponding to the original boot program, that is, an original file of the boot program, is stored in the first partition. This process can be illustrated with reference to the "1 program download" process in fig. 3.
Before step 103, a reboot operation needs to be performed on the chip, so that the chip is already the latest written data when reading the data of the second partition and the third partition.
Based on this, in an embodiment, before upgrading an application program based on an upgrade file of the application program by using an original file of a boot program stored in the first partition, the method further includes:
and carrying out a first restart operation on the chip by an original bootstrap program.
In step 103, the main objectives are: and upgrading the application program by using the original boot lead sequence. Here, the upgraded application program is mainly added with a boot program upgrade processing command compared with the application program before upgrading, and the command performs an operation of reading the upgrade file of the boot program from the third partition and writing the read upgrade file of the boot program into the first partition to replace the original file of the boot program in the first partition. In practical applications, the command is specifically realized by calling functions in the application program for reading and writing the on-chip memory.
In an embodiment, the upgrading the application program based on the upgrade file of the application program by using the original boot program file stored in the first partition includes:
and operating the original bootstrap program, and booting and loading the upgrade file of the application program by the original bootstrap program.
In practice, the process can refer to the process schematic of "2 boot, load" in fig. 3.
In step 104, in the actual application, after the application program is upgraded, the upgraded application program is run, and when the upgraded application program is run, the above-mentioned boot program upgrade processing command is executed, so as to replace the original file of the boot program in the first partition with the upgrade file of the boot program. At this point, the boot program has already implemented the upgrade. This process can be illustrated with reference to the process "replacement of 3 boot program" in fig. 3.
After step 104, the chip needs to be restarted again, so that the chip reads the upgrade file of the boot program currently stored in the first area, and runs the upgraded boot program.
Based on this, in an embodiment, after the upgraded application program is executed, the method further includes:
performing a second reboot operation on the chip by the original boot program; and after the second restart operation is finished, the chip runs the upgraded bootstrap program.
According to the bootstrap program upgrading method provided by the embodiment of the invention, a first upgrading package is obtained, wherein the first upgrading package comprises an upgrading file of an application program and an upgrading file of a bootstrap program; respectively storing the upgrade files of the application programs and the upgrade files of the bootstrap programs into a second partition and a third partition of a chip memory; the memory includes a first partition, a second partition, and a third partition; the first partition is used for storing an operation file of a bootstrap program; the second partition is used for storing an upgrade file of the application program; the third partition is used for storing an upgrade file of the bootstrap program; upgrading the application program based on the upgrading file of the application program by using the original file of the bootstrap program stored in the first partition; running the upgraded application program; and reading the upgrade file of the bootstrap program from the third partition by the upgraded application program, and replacing the original file of the bootstrap program in the first partition by using the read upgrade file of the bootstrap program. In the embodiment of the invention, the upgrading file of the bootstrap program and the upgrading file of the application program are imported into different partitions of a chip memory, and the function of reading and writing the chip memory is added in the application program; in the embodiment of the invention, after the original bootstrap program is used for upgrading the application program, the application program after running the upgrade can execute the corresponding bootstrap program upgrade command, namely the upgrade file of the bootstrap program read from the third partition is written into the first partition for storing the bootstrap program operation file, and then the bootstrap program run by the chip is the upgrade file of the bootstrap program read from the first partition.
The present invention will be described in further detail with reference to the following application examples.
In an application embodiment of the present invention, a chip is an MCU in an optical module, a memory is Flash, and fig. 4 is a schematic diagram illustrating an implementation flow of upgrading a boot program according to an application embodiment of the present invention. As shown in fig. 4, the method comprises the steps of:
step 401: acquiring a first upgrade package;
in practical application, the upper computer firstly packages the binary file of the application program to be upgraded and the binary file of the bootstrap program to be upgraded into a first upgrade package according to the positions of a second partition and a third partition in a Flash partition on the MCU chip. The MCU acquires a first upgrade package sent by the upper computer. After step 401 is completed, the process proceeds to step 402.
It should be noted that: before step 401, the upper computer needs to combine the binary file of the application program to be upgraded and the binary file of the bootstrap program to be upgraded into a first upgrade package according to special requirements. The special requirements here may be: (1) the capacity of the original bootstrap program, the application program to be upgraded and the bootstrap program to be upgraded must be smaller than the capacity of the Flash on the MCU chip; (2) when a binary file is formed, a file check code is added; and when an upgrade package is formed, adding an upgrade package check code.
Step 402: downloading the first upgrade package;
in practical application, the first upgrade package is downloaded to a specified position according to an upgrade process in the related technology. After step 402 is completed, the process proceeds to step 403.
Step 403: verifying the first upgrade package;
in practical applications, the verification here may be to verify the integrity of the first upgrade package, specifically: data loss is easy to generate in the transmission process of the upgrade package, so that the upgrade package cannot be normally used.
When the verification result is passed, the step 404 is carried out; when the verification result is not passed, the procedure proceeds to step 411.
Step 404: writing the first upgrade package into a memory of an MCU;
in practical application, the original bootstrap program can write the data in the first upgrade package into Flash on the MCU chip. At the moment, the second partition is replaced by the upgrade file of the application program in the first upgrade package; the third partition is replaced with an upgrade file of the boot program in the first upgrade package. At this point, it is the original file of the boot program that is stored in the first partition. After step 404 is completed, the process proceeds to step 405.
Step 405: restarting the MCU;
in practical applications, the original boot program can restart the chip. After step 405 is completed, the process proceeds to step 406.
Step 406: guiding and loading the upgrade file of the application program by using the original file of the guide program;
in practical application, the application program to be upgraded in the second partition can be booted and loaded by the original bootstrap program. After step 406 is completed, the process proceeds to step 407.
Step 407: verifying the binary file of the bootstrap program to be upgraded;
in practical applications, the verification here may be to verify the integrity of the binary file of the boot program to be upgraded, specifically: the integrity of the binary file of the bootstrap program to be upgraded can be detected in a mode of checking the check code so as to predict whether the binary file of the bootstrap program to be upgraded is available in advance.
When the verification result is passed, the step 408 is carried out; when the verification result is not passed, the procedure proceeds to step 411.
Step 408: executing the bootstrap program in the replacement partition I by the upgraded application program (namely the application program to be upgraded);
in actual application, the boot program to be upgraded in the third partition is written into the first partition through the Flash read-write interface on the MCU chip so as to replace the original boot program in the first partition.
Step 409: restarting the MCU;
in practical applications, the original boot program can restart the chip. After step 409 is completed, the process proceeds to step 410.
Step 410: the boot program is upgraded successfully;
in practical application, after the restart operation in step 409 is performed, the MCU reads the upgrade file of the currently stored boot program in the first area, that is, runs the upgraded boot program, and at this time, the boot program is upgraded successfully.
Step 411: the boot program upgrade fails.
The application embodiment of the invention adds a function method for upgrading the bootstrap program under the condition of being compatible with the original online upgrading process of the application program. Specifically, a binary file of a bootstrap program to be upgraded is packaged in an application program upgrade package, the application program to be upgraded and the bootstrap program to be upgraded are written into a second partition and a third partition corresponding to a Flash of an MCU through an original application program online upgrade flow, and after the application program to be upgraded is booted and loaded, a new bootstrap program to be upgraded is introduced into a first partition on the Flash of the MCU by using the application program to be upgraded (i.e. the upgraded application program), and the original bootstrap program is replaced. The whole upgrading process is completely compatible with the original upgrading system, and the whole upgrading process can not cause the interruption and exit of any optical service. Therefore, the boot program and the application program of the optical module can be upgraded and updated on line.
