The following description is made with reference to examples.
Fig. 4 is a schematic diagram of a scenario of program update according to an embodiment of the present invention. In this example, the first bootstrap program is bootstrap program 1, and the first application program is application program 1. As shown in fig. 4, after the embedded device is powered on, the boot program 1 is started from the address a of the memory. After that, it jumps to the running address B of the application 1. If the program does not need to be upgraded, application 1 will be run.

Optionally, the second boot program may be preceded by a second application trailer.
It should be noted that the first boot program and the second boot program may be different or the same. The first application and the second application may or may not be the same.
The following description will be given by taking fig. 4 as an example. The second bootstrap program is bootstrap program 2, and the second application program is application program 2. As shown in fig. 4, the boot program 1 is addressed to the running address B of the application program 1. If the firmware upgrade package is received, the application 1 is deleted. And, storing the firmware upgrade package. In this example, the initial memory address of the application 2 is address C.

and receiving a firmware upgrading packet from the controller, wherein the firmware upgrading packet is received by the controller from the server through the network adapter.
Specifically, refer to fig. 1 and fig. 2, which are not described herein again.
Alternatively, the firmware upgrade package may include a plurality of data packages. In S302, receiving the firmware upgrade package may include:
a plurality of data packets are received on a packet-by-packet basis.
Optionally, in one implementation, the embedded device may receive a plurality of data packets from the server on a packet-by-packet basis.
Alternatively, in another implementation, the controller may receive a firmware upgrade package from a server. The controller may split the firmware upgrade package into a plurality of data packets, which are sent to the embedded device on a packet-by-packet basis. Accordingly, the embedded device may receive multiple data packets from the controller on a packet-by-packet basis.
Optionally, in another implementation, the controller may receive a plurality of data packets from the server packet by packet, and send the data packets to the embedded device packet by packet. Accordingly, the embedded device may receive multiple data packets from the controller on a packet-by-packet basis.
It should be noted that, in the present embodiment, the number of packets and the size of each packet are not limited.
Accordingly, in S302, storing the firmware upgrade package may include:

And the second jump address is the running address of the second application program.
And S304, operating the second application program according to the second jump address so as to replace the first bootstrap program with the second bootstrap program.
Specifically, after the firmware upgrade package is stored, the first boot program is restarted. The first boot program may be automatically addressed to the running address of the second application program. At this time, the jump address of the first boot program is referred to as a second jump address, and the second jump address is a running address of the second application program. And then, by running the second application program, the first boot program can be replaced by the second boot program, and the upgrading of the old firmware into the new firmware is completed. And then the embedded device can be powered on again, and the second bootstrap program can automatically address the running address of the second application program and run the second application program.
Optionally, in S304, running the second application according to the second jump address to replace the first bootstrap with the second bootstrap may include:
the first boot program is deleted.
And storing the second bootstrap program according to the initial storage address of the first bootstrap program.
And deleting the second boot program in the stored firmware upgrade package.
The following description will be given by taking fig. 4 as an example.
After the embedded device stores the application 2 and the bootstrap program 2, the bootstrap program 1 is restarted. The boot program 1 is automatically addressed to the running address C of the application program 2. Then, the operation address C of the application 2 is jumped to, and the application 2 is operated. At the beginning of the operation, the boot program 1 is deleted, the boot program 2 is stored in the address A, and the boot program 2 behind the application program 2 is deleted, so that the firmware upgrade is completed.
Therefore, the program upgrading method provided by the embodiment can realize the program upgrading of the embedded device by automatically addressing the running address of the application program through the bootstrap program. In particular, the old application may be deleted upon receipt of the new firmware by the old boot program automatically addressing the running address of the old application. The old bootstrap program automatically addresses the running address of the new application program and skips to execute the new application program, so that the old bootstrap program can be replaced by the new bootstrap program to finish program upgrading. Because the expensive burner is not adopted for program upgrading, and the product is not required to be disassembled, the efficiency of program upgrading of the embedded device is improved, and the operation complexity and the cost are reduced. Moreover, the bootstrap program can automatically address the running address of the application program and jump to execute the application program, so that the sizes of the application program and the bootstrap program in the new firmware can be changed at will according to requirements. When the program is upgraded, the running address of the application program can be randomly modified, and the situation that a new application program covers a new bootstrap program or the new bootstrap program covers the new application program is avoided. Coupling degree between the bootstrap program and the application program is reduced, flexibility of storage space change during upgrading of the bootstrap program and the application program is improved, and program upgrading effect is improved.
Optionally, in an implementation manner, in S303, acquiring the second jump address of the first bootstrap program may include:
and determining whether the storage area is the first storage area of the second application program one by one according to the arrangement sequence of the storage areas from the terminal address of the first bootstrap program.
And if the storage area is determined to be the first storage area of the second application program, determining the running address of the second application program stored in the first storage area as a second jump address.
Specifically, the storage space in the memory may be divided into a plurality of storage areas in advance. In this embodiment, the dividing manner of the storage areas, the number of the storage areas, and the size of each storage area are not limited. The storage area may be different according to the embedded device and the memory.
And determining whether the storage area is the first storage area of the second application program one by one according to the arrangement sequence of the storage areas from the terminal address of the first bootstrap program. And if the current storage area is not the first storage area of the second application program, continuously determining whether the next storage area of the current storage area is the first storage area of the second application program according to the arrangement sequence of the storage areas until the first storage area of the second application program is found. If the current storage area is the first storage area of the second application, the running address of the second application stored in the first storage area of the second application may be obtained and determined as the second jump address of the first boot program.
Typically, the boot program is in close proximity or very small separation from the application program. At the current stage of program upgrade, the bootstrap program is an old bootstrap program, and the application program is a new application program. Whether the storage areas are the first storage area of the new application program is determined one by one according to the sequence of the storage areas from the end address of the old bootstrap program, and the accuracy and the efficiency of finding the first storage area of the new application program are improved.
Optionally, determining whether the storage area is the first storage area of the second application program may include:
and verifying the data stored in the storage area by adopting a verification algorithm.
And if the verification is passed, determining that the storage area is the first storage area of the second application program.
Specifically, the verification algorithm is a verification operation performed to ensure the integrity of data. There are various ways to implement the checking algorithm. For example, a check value may be calculated from the data stored in the storage area and compared to the check value stored in the storage area. If the two check values are the same, the check passes. The embodiment does not limit the specific implementation manner of the verification algorithm. For example, the Check Algorithm may be a Message Digest Algorithm (MD 5), a Cyclic Redundancy Check (CRC), or the like.
The first storage area of the second application program is determined through the verification algorithm, and the accuracy of finding the first storage area of the new application program is improved.
Optionally, before determining the running address of the second application program stored in the first storage area as the second jump address, the method may further include:
and verifying the data stored in each storage area by adopting a verification algorithm from the second storage area of the second application program to the last storage area of the second application program.
And if all the storage areas of the second application program pass the verification, determining the running address of the second application program stored in the first storage area as a second jump address.
And checking all storage areas of the second application program through a checking algorithm. And only when all the storage areas of the second application program pass the verification, determining the running address of the second application program stored in the first storage area of the second application program as the second jump address of the first bootstrap program, thereby further improving the accuracy of the first bootstrap program for automatically addressing the running address of the second application program.
Optionally, before verifying the data stored in each storage area by using a verification algorithm, the method may further include:
a memory space value of the second application stored in the first memory area is obtained.
And determining a second storage area to a last storage area of the second application program according to the storage space value of the second application program.
Specifically, the first storage area of the second application program stores the running address of the second application program, and also stores the storage space value of the second application program. The storage space value is the size of the second application. According to the running address and the storage space value of the second application program, all the storage areas of the second application program can be obtained.
It should be noted that the above-mentioned embodiments related to obtaining the second jump address are also applicable to obtaining the first jump address.
Optionally, in S302, before storing the firmware upgrade package, the method may further include:
and analyzing the second application program to obtain the running address of the second application program.
Accordingly, obtaining the second jump address of the first boot program may include:
and determining the running address of the second application program as a second jump address.
In this implementation, by parsing the second application, the running address of the second application may be obtained and determined as the second jump address of the first boot program. The efficiency of obtaining the second jump address is improved.
Optionally, analyzing the second application program to obtain the operation address of the second application program may include:
and temporarily storing the first data packet of the second application program in the memory.
And analyzing the first data packet to obtain the running address of the second application program.
Specifically, the second application may be received on a packet-by-packet basis. The running address and/or the memory space value of the second application is typically stored in the front end of the second application. Therefore, the first data packet of the second application program can be temporarily stored in the memory and analyzed. So that the running address and/or the memory space value of the second application can be retrieved.
The second application program does not need to be completely stored and then analyzed, and the operation address and/or the storage space value of the second application program can be obtained only by analyzing the first data packet, so that the processing efficiency is prompted.
Optionally, in the method for upgrading a program provided in this embodiment, in S302, storing the firmware upgrade package may include:
a memory space value of the second boot program is obtained.
And determining the initial storage address for storing the firmware upgrade package according to the storage space value of the second boot program and the initial storage address of the first boot program.
And storing the firmware upgrading packet according to the initial storage address of the firmware upgrading packet.
Specifically, after the program upgrade, the first boot program is replaced with the second boot program. The starting memory addresses of the first boot program and the second boot program are the same. Therefore, the initial storage address of the firmware upgrade package can be determined according to the size of the second boot program and the initial storage address of the first boot program in the firmware upgrade package, and it is ensured that the second boot program does not cover the second application program or the second application program does not cover the second boot program after the program of the embedded device is upgraded. Therefore, the sizes of the application program and the bootstrap program in the new firmware can be changed at will according to needs, the flexibility of storage space change when the bootstrap program and the application program are upgraded is improved, and the effect of program upgrading is improved.
Optionally, a difference between the start storage address of the firmware upgrade package and the start storage address of the first boot program is greater than or equal to a preset value.
It should be noted that, the specific value of the preset value is not limited in this embodiment. Optionally, the preset value may be a memory space value of the second boot program.
This is illustrated by way of example.
In one example, as shown in FIG. 4, the starting memory address of application 2 is address C. The boot program 1 has a starting memory address of address a. The difference between address C and address a is equal to the memory space value of the boot-loader 2. When the program is upgraded, the bootstrap program 1 is replaced by the bootstrap program 2. There is no gap between the bootstrap 2 and the application 2. The storage space is saved.
In another example, fig. 5 is a schematic diagram of another scenario of program update provided in the first embodiment of the present invention. As shown in fig. 5, the initial storage address of the application 2 is address D. The boot program 1 has a starting memory address of address a. The difference between address D and address a is greater than the memory space value of bootstrap 2. When the program is upgraded, the bootstrap program 1 is replaced by the bootstrap program 2. There is a gap between the bootstrap 2 and the application 2.
The embodiment provides a program upgrading method, which includes: starting a first bootstrap program, obtaining a first jump address of the first bootstrap program, wherein the first jump address is a running address of a first application program, if a firmware upgrade package is received, deleting the first application program according to the first jump address, and storing the firmware upgrade package, wherein the firmware upgrade package comprises a second application program and a second bootstrap program, restarting the first bootstrap program, obtaining a second jump address of the first bootstrap program, wherein the second jump address is a running address of the second application program, and running the second application program according to the second jump address so as to replace the first bootstrap program with the second bootstrap program. According to the program upgrading method provided by the embodiment, the operating address of the application program is automatically addressed through the bootstrap program, the application program is operated, the old application program can be deleted, the old bootstrap program is replaced by the new bootstrap program, and the program upgrading is completed. The efficiency of embedded equipment program upgrading is promoted, and the operation complexity and cost are reduced. Moreover, the flexibility of storage space change during upgrading of the bootstrap program and the application program is improved, and the effect of program upgrading is improved.
Fig. 6 is a schematic diagram of a scenario of program update according to a second embodiment of the present invention. The program upgrading method provided in this embodiment is similar to the program upgrading method provided in the embodiments shown in fig. 3 to 5, and the technical principle and the technical effect are similar to each other, and are not described again here.
The scenario shown in the present embodiment differs from the scenario shown in fig. 4 in that: in fig. 4, the firmware upgrade package includes an application program 2 and a boot program 2. In the present embodiment, the firmware upgrade package includes an application program 3 and a boot program 2. The boot program 1 can be upgraded to the boot program 2 by adding the same boot program to different application programs.
Specifically, in fig. 6, the first bootstrap program is bootstrap program 1, and the first application program is application program 1. The second bootstrap program is bootstrap program 3, and the second application program is application program 2.
After the embedded device is powered on, the bootstrap program 1 is started from the address a of the memory. After that, it jumps to the running address B of the application 1. Since the firmware upgrade package is received, the upgrade is performed according to the firmware upgrade package. The firmware upgrade package includes an application program 3 and a boot program 2. And deleting the application program 1 according to the running address B of the application program 1. And, the firmware upgrade package is stored at address C.
The boot program 1 is restarted. The boot program 1 is automatically addressed to the running address C of the application program 3. After that, the execution application 3 is jumped. At the beginning of the operation, the boot program 1 is deleted, the boot program 2 is stored in the address A, and the boot program 2 behind the application program 3 is deleted, so that the firmware upgrade is completed.
Fig. 7 is a schematic diagram of a scenario of program update according to a third embodiment of the present invention. The present embodiment provides another implementation manner of the program upgrading method based on the embodiments shown in fig. 3 to fig. 6.
Specifically, in S304, before executing the second application according to the second jump address to replace the first boot program with the second boot program, the method may further include:
and judging whether the first bootstrap program is the same as the second bootstrap program.
And if the first bootstrap program is different from the second bootstrap program, executing a second application program operated according to the second jump address so as to replace the first bootstrap program with the second bootstrap program.
And if the first boot program is the same as the second boot program, deleting the second boot program in the stored firmware upgrade package, and running the second application program.
This will be explained with reference to fig. 7.
In fig. 7, the first bootstrap program is bootstrap program 2, and the first application program is application program 2. The second bootstrap program is bootstrap program 3, and the second application program is application program 2.
After the embedded device is powered on, the bootstrap program 2 is started from the address a of the memory. After that, it jumps to the running address C of the application 2. Since the firmware upgrade package is received, the upgrade is performed according to the firmware upgrade package. The firmware upgrade package includes an application program 3 and a boot program 2. Because the current boot program of the embedded device is the same as the boot program in the firmware upgrade package and is boot program 2, the boot program of the embedded device does not need to be replaced, and only the application program needs to be replaced. At this time, the boot program 2 following the application program 3 is deleted, and the application program 3 is run.
The first boot program and the second boot program have different scenarios, and can be seen in fig. 4 to 6. And will not be described in detail herein.
