Detailed Description
The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.
At present, the upgrade data receiving of the program to be upgraded generally has two schemes, namely, firstly, receiving the upgrade data through a backup area, and after the upgrade data is received, if the upgrade data is complete, copying the upgrade data of the backup area to the program area to be upgraded to realize the program upgrade, and secondly, firstly, erasing the program area to be upgraded and then directly storing the upgrade data into the program area to be upgraded. The first scheme has the advantages that when the upgrade data is received incompletely, the system can continue to operate based on the original program, the disadvantage is that the device must have enough memory space to store the upgrade data, the second scheme has the advantage that no additional backup area is needed to store the upgrade data, and the disadvantage is that if the upgrade data is received incompletely, the system cannot continue to operate. For electronic devices, there may be differences in memory space occupied by software at different stages. For example, during early debugging, the function is simpler, the memory occupied by the software is smaller, the storage space of the backup area is enough for storing the upgrade data, and along with the perfection of the program function, the memory occupied by the software is larger, and the storage space of the backup area is difficult to store the upgrade data. As described in the background art, in the prior art, only one upgrading mode is generally adopted to upgrade the program in the MCU, so that the upgrading mode cannot be flexibly switched, and the method is difficult to adapt to the upgrading data storage requirements of different stages, so that the reliability of program upgrading is lower.
Aiming at the problems, the embodiment of the invention provides an upgrading method of electronic equipment. Fig. 1 is a flow chart of an upgrade method of an electronic device according to an embodiment of the present invention. The method may be performed by an upgrade apparatus of an electronic device, which may be implemented in software and/or hardware, where the apparatus may be configured in an electronic device, for example, a power electronic device, a server, or a terminal device, where typical terminal devices include a mobile terminal, and specifically include a mobile phone, a computer, or a tablet computer. The electronic device in this embodiment is configured with a micro control unit, and this embodiment is applicable to a case of upgrading a program to be upgraded in an MCU of the micro control unit, where a memory area of the micro control unit includes a first memory area, a second memory area, and a memory area to be upgraded, and accordingly, referring to fig. 1, an upgrading method of the electronic device includes the following steps:
S110, judging whether the first storage area has a space for storing upgrade data.
Specifically, the electronic device in the embodiment of the present invention includes a power electronic device, which may be an electric energy conversion device in a photovoltaic system, such as an inverter or the like. The first storage area, the second storage area and the storage area to be upgraded are all independent storage areas. The program to be upgraded in the micro control unit MCU can be an application program or a bootstrap program. Optionally, when the program to be upgraded is an application program, the storage area to be upgraded is used for storing application program data, the second storage area is a guide area, and when the program to be upgraded is a guide program, the storage area to be upgraded is used for storing guide program data, and the second storage area is an application area. The Boot area (i.e., boot area) stores a system Boot file for booting. The application area is the APP area. The first storage area may be used to store upgrade data of the program to be upgraded, for example, the memory area of the micro control unit further includes a remaining memory area, and the first storage area may be one of the remaining memory areas, where an area other than the first storage area in the remaining memory area may be either empty or used to store other data, for example, operation state data of the photovoltaic system, and the like. The size of the first memory area may vary with the use of areas other than the first memory area in the remaining memory areas.
Before upgrading the program to be upgraded, whether the first storage area has a space for storing upgrade data is judged. When the current available memory space of the first memory area is insufficient to store the upgrade data, it may be determined that the first memory area has a space to store the upgrade data, and when the current available memory space of the first memory area is insufficient to store the upgrade data, it may be determined that the first memory area does not have a space to store the upgrade data.
S120, when the first storage area is provided with a space for storing upgrade data, receiving an upgrade instruction through the storage area to be upgraded or the second storage area to store the upgrade data in the upgrade instruction into the first storage area, and when the first storage area is not provided with a space for storing the upgrade data, receiving the upgrade instruction through the second storage area to store the upgrade data in the upgrade instruction into the storage area to be upgraded.
In one embodiment, the to-be-upgraded memory area is used for storing application program data, that is, the to-be-upgraded memory area is an APP area, and the second memory area is a boot area. When the application program is upgraded, if the first storage area has a space for storing upgrade data, an upgrade instruction is received through the storage area to be upgraded or the second storage area, so that the upgrade data corresponding to the upgrade instruction is stored in the first storage area in response to the upgrade instruction in the storage area to be upgraded or the second storage area. After the first storage area receives all the upgrade data completely, the upgrade data in the first storage area can be used for replacing the application program data currently stored in the storage area to be upgraded, and the data stored in the storage area to be upgraded is the upgraded application program data at the moment, so that the upgrade of the application program is realized. The advantage of this is that during the upgrade process, the storage area to be upgraded still stores the application data before the upgrade, and even if the upgrade data received by the first storage area is incomplete, the device can continue to operate based on the application data before the upgrade stored in the storage area to be upgraded.
When the application program is upgraded, if the first storage area does not have a space for storing upgrade data, the second storage area, namely the guide area, can respond to an upgrade instruction during the upgrade, firstly erase the current application program data stored in the storage area to be upgraded, and then store the upgrade data into the storage area to be upgraded, and at the moment, the data stored in the storage area to be upgraded is already the upgraded application program data, thereby realizing the upgrade of the application program. The advantage of this is that an upgrade of the application program is still enabled in case the memory of the first storage area is insufficient to store upgrade data.
In another embodiment, the to-be-upgraded program is a boot program, the to-be-upgraded storage area is used for storing boot program data, and the second storage area is an application area (APP area). When the boot program is upgraded, if the first storage area has a space for storing upgrade data, an upgrade instruction is received through the storage area to be upgraded or the second storage area, so that the upgrade data corresponding to the upgrade instruction is stored in the first storage area in response to the upgrade instruction in the storage area to be upgraded or the second storage area. After the first storage area receives all the upgrade data completely, the upgrade data in the first storage area can be used for replacing the currently stored bootstrap data of the storage area to be upgraded, and the data stored in the storage area to be upgraded is already the upgraded bootstrap data at the moment, so that the upgrade of the bootstrap is realized. If the first storage area does not have a space for storing upgrade data, the second storage area, namely the application area, can respond to the upgrade instruction, firstly erase the currently stored bootstrap program data of the storage area to be upgraded, and then store the upgrade data into the storage area to be upgraded, and at the moment, the data stored in the storage area to be upgraded is already the upgraded bootstrap program data, thereby realizing the upgrade of the bootstrap program.
The technical scheme of the embodiment of the invention is suitable for upgrading the program to be upgraded in the MCU of the electronic equipment, and the program to be upgraded can be an application program or a guide program. When the first storage area has a space for storing upgrade data, an upgrade instruction is received through the storage area to be upgraded or the second storage area, so that the upgrade data in the upgrade instruction is stored in the first storage area, and the upgrade program to be upgraded is upgraded, when the first storage area does not have the space for storing the upgrade data, the upgrade instruction is received through the second storage area, so that the upgrade data in the upgrade instruction is stored in the storage area to be upgraded, and the self-adaptive adjustment of the receiving mode of the upgrade data according to the memory space required by the upgrade data is realized. For the electronic equipment, the memory space occupied by the programs to be upgraded at different stages is different, the scheme is beneficial to meeting the upgrade data receiving requirements of the programs to be upgraded at different stages in the electronic equipment, the memory cost of the system is not required to be increased, the reliability of the programs to be upgraded is improved, and the influence of the upgrading process on the normal operation of the equipment is reduced.
Fig. 2 is a flowchart of another method for upgrading electronic equipment according to an embodiment of the present invention. On the basis of the above embodiment, the present embodiment optimizes an upgrade method of an electronic device. Optionally, in this embodiment and the following embodiments, when the program to be upgraded is an application program, the storage area to be upgraded is used to store application program data, the second storage area is a boot area, and when the program to be upgraded is a boot program, the storage area to be upgraded is used to store boot program data, and the second storage area is an application area for illustration. Correspondingly, referring to fig. 2, the method of the present embodiment specifically includes the following steps:
S210, receiving an instruction for entering an upgrade mode.
The instruction of entering the upgrade mode is different from the upgrade instruction in that the upgrade instruction includes upgrade data required for upgrading a program to be upgraded, and the instruction of entering the upgrade mode includes attribute information of the upgrade data, for example, the instruction of entering the upgrade mode includes length information of the upgrade data, and the like. The instruction for entering the upgrade mode is an instruction converted by a communication protocol according to the upgrade file, and the length information of the upgrade data may be directly extracted from the instruction for entering the upgrade mode, or the length information of the upgrade data may be extracted from the upgrade file.
S220, acquiring length information of the upgrade data, total memory of the first storage area and currently used memory.
S230, calculating the current residual available memory of the first storage area according to the difference between the total memory and the current used memory.
S240, judging whether the first storage area has a space for storing upgrade data according to the relation between the current residual available memory of the first storage area and the length of the upgrade data.
If the current remaining available memory of the first storage area is greater than or equal to the length of the upgrade data, it is determined that the first storage area has a space for storing the upgrade data, and step S250 is performed, and if the current remaining available memory of the first storage area is less than the length of the upgrade data, it is determined that the first storage area does not have a space for storing the upgrade data, and step S260 is performed.
For example, the length information of the upgrade data may represent the amount of memory that the upgrade data needs to occupy. The current residual available memory of the first storage area is equal to the difference between the total memory of the first storage area and the current used memory, if the residual available memory is larger than or equal to the length of the upgrade data, the current residual memory of the first storage area can store the upgrade data, and if the residual available memory is smaller than the length of the upgrade data, the current residual memory of the first storage area cannot store the upgrade data. When the first storage area is one storage area in the remaining memory areas, the size of the first storage area changes along with the use condition of the areas except the first storage area in the remaining memory areas, so that the total memory of the first storage area can be determined according to the total memory of the remaining memory areas and the use condition of the areas except the first storage area in the remaining memory areas, and then the current remaining available memory of the first storage area is calculated.
When the program to be upgraded in the MCU is upgraded, communication can be established between the MCU and the upper computer, and an instruction for entering an upgrade mode and an upgrade instruction are issued to the MCU through the upper computer, or the MCU can also be established between the MCU and the upper computer through the upper communication unit, namely, the upper computer issues the instruction for entering the upgrade mode and the upgrade instruction to the MCU through the upper communication unit. The step of determining whether the first storage area can store the upgrade data may be performed by an upper computer or by the MCU. The step of the MCU subsequently receiving the upgrade data in response to the upgrade instruction to upgrade the program to be upgraded can be executed under the dispatching of the upper computer or the upper communication unit or can be executed autonomously by the MCU.
S250, receiving an upgrade instruction through the storage area to be upgraded or the second storage area so as to store upgrade data in the upgrade instruction into the first storage area.
S260, receiving the upgrade instruction through the second storage area so as to store the upgrade data in the upgrade instruction into the storage area to be upgraded.
Fig. 3 is a flowchart of another method for upgrading electronic equipment according to an embodiment of the present invention. The embodiment optimizes the upgrading method of the electronic equipment. Referring to fig. 3, the method of this embodiment specifically includes the following steps:
S301, receiving an instruction for entering an upgrade mode.
S302, judging whether the first storage area has a space for storing upgrade data.
If the first storage area has a space for storing upgrade data, step S303 is performed, and if the first storage area does not have a space for storing upgrade data, step S308 is performed.
S303, receiving an upgrade instruction through the storage area to be upgraded or the second storage area so as to store upgrade data in the upgrade instruction into the first storage area.
S304, judging whether the upgrade data stored in the first storage area is correct and complete.
Specifically, after the upgrade data is stored in the first storage area, whether the upgrade data stored in the first storage area is correct and complete is judged. If the upgrade data stored in the first storage area is correct and complete, S305 is performed, and if the upgrade data stored in the first storage area is incorrect and/or incomplete, S307 is performed.
When the first storage area is provided with a space for storing upgrade data, the upgrade instruction is received through the storage area to be upgraded or the second storage area, so that the upgrade data in the upgrade instruction is stored in the first storage area, and the program to be upgraded is upgraded. If the upgrade data received by the first storage area is correct and complete, the subsequent upgrade steps can be normally performed.
S305, replacing the program data to be upgraded in the storage area to be upgraded with the upgrade data stored in the first storage area through the second storage area.
When the first storage area has a space for storing upgrade data, if the upgrade instruction is received through the storage area to be upgraded, the storage area to be upgraded needs to jump to the second storage area to execute step S305, and if the upgrade instruction is received through the second storage area, the jump is not needed, and step S305 can be directly executed.
S306, finishing the upgrading of the program to be upgraded.
Specifically, the upgrade data stored in the first storage area is copied to the to-be-upgraded storage area through the second storage area, so that the upgrade data stored in the first storage area is used for replacing the to-be-upgraded program data in the to-be-upgraded storage area, after the data in the to-be-upgraded storage area is replaced with the upgrade data, the second storage area jumps back to the to-be-upgraded storage area, and at the moment, the data in the to-be-upgraded storage area is updated to the upgraded data, so that the upgrade of the to-be-upgraded program is completed. Optionally, after step S306, the upgrade data temporarily stored in the first storage area may be cleared.
S307, the upgrade data in the first storage area is emptied.
Optionally, in an embodiment, if the upgrade data received by the first storage area is incorrect and/or incomplete, the second storage area or the to-be-upgraded storage area may be selected to empty the upgrade data currently stored in the first storage area, so that the system can be prevented from replacing the to-be-upgraded program data based on the incorrect and/or incomplete upgrade data, so that the system can still operate normally based on the to-be-upgraded program data in the to-be-upgraded storage area.
Alternatively, in another embodiment, if the upgrade data received by the first storage area is incorrect and/or incomplete, no other operation may be performed.
S308, jumping to the second storage area.
S309, receiving the upgrade instruction through the second storage area, so as to store the upgrade data in the upgrade instruction into the storage area to be upgraded.
Specifically, when the first storage area does not have a space for storing the upgrade data, the second storage area may be skipped to receive the upgrade instruction through the second storage area, thereby storing the upgrade data in the storage area to be upgraded in response to the upgrade instruction. Optionally, the second storage area responds to the upgrade instruction, original program data to be upgraded in the storage area to be upgraded is firstly erased, and then the upgrade data is stored in the storage area to be upgraded.
S310, judging whether the upgrade data stored in the storage area to be upgraded is correct and complete.
If the upgrade data stored in the storage area to be upgraded is correct and complete, step S311 is executed, and if the upgrade data stored in the storage area to be upgraded is incorrect and/or incomplete, step S312 is executed.
S311, finishing the upgrading of the program to be upgraded.
Specifically, after the storage area to be upgraded completely and correctly receives the upgrade data, the second storage area jumps back to the storage area to be upgraded, and at this time, the data in the storage area to be upgraded is updated into the upgraded data, thereby completing the upgrade of the program to be upgraded.
S312, waiting for upgrading again.
On the basis of the above embodiment, optionally, the memory area of the MCU further includes an upgrade flag storage area, where the upgrade flag storage area is used to store an upgrade flag, and the upgrade flag includes an upgrade completion flag, where the upgrade completion flag is used to characterize that the first storage area has stored correct and complete upgrade data. For example, the memory area of the micro control unit MCU may be divided into a boot area, an APP area, an upgrade flag storage area, and a remaining memory area. The first storage area is a storage area in the residual memory area, one of the second storage area and the storage area to be upgraded is a guide area, the other is an APP area, and the upgrading mark storage area is used for storing upgrading marks representing different upgrading states. Accordingly, after step S304, the method for upgrading an electronic device further includes:
If the upgrade data stored in the first storage area is correct and complete, the upgrade completion flag is written into the upgrade flag storage area, and if the upgrade data stored in the first storage area is incorrect and/or incomplete, the upgrade completion flag is not written into the upgrade flag storage area.
If the upgrade completion flag is written into the upgrade flag storage area, replacing the program data to be upgraded in the storage area to be upgraded with the upgrade data stored in the first storage area through the second storage area, and after the program data to be upgraded in the storage area to be upgraded is replaced with the upgrade data of the first storage area, clearing the upgrade completion flag to complete the upgrade of the program to be upgraded.
Specifically, when the first storage area has a space for storing upgrade data, the upgrade instruction is received through the storage area to be upgraded or the second storage area, so that the upgrade data in the upgrade instruction is stored in the first storage area, and the program to be upgraded is upgraded. After the upgrade data is stored by the first storage area, whether the upgrade data stored by the first storage area is correct and complete is judged. If the upgrade data received by the first storage area is correct and complete, an upgrade completion flag may be written into the upgrade flag storage area to indicate that the upgrade data has been received correctly and completely. If the upgrade data received by the first storage area is incorrect and/or incomplete, the upgrade completion flag is not written into the upgrade flag storage area.
If the upgrade completion flag is written into the upgrade flag storage area, the upgrade completion flag is indicated to be valid currently, and if the upgrade completion flag is not written into the upgrade flag storage area, the upgrade completion flag is indicated to be invalid currently. After determining whether to write the "upgrade completion flag" into the upgrade flag storage area, and before performing step S305, the upgrade flag in the upgrade flag storage area is read to determine the upgrade status. If the "upgrade completion flag" is valid, step S305 is performed to replace the program data to be upgraded in the storage area to be upgraded with the upgrade data stored in the first storage area through the second storage area. After the data in the storage area to be upgraded is replaced by the upgrade data, the upgrade completion flag is cleared, and at the moment, the data in the storage area to be upgraded is updated into the upgraded data, so that the upgrade of the program to be upgraded is completed.
On the basis of the above embodiment, optionally, the upgrade flag further comprises an upgrade flag, the upgrade flag being used for characterizing that the first storage area has no space for storing upgrade data, and the upgrade instruction needs to be received through the second storage area, and accordingly, after determining that the first storage area has no space for storing upgrade data, and before executing step S308, the upgrade method of the electronic device further comprises writing the upgrade flag into the upgrade flag storage area.
The method comprises the steps of writing an upgrading mark into an upgrading mark storage area, receiving an upgrading instruction through a second storage area if the upgrading mark is written into the upgrading mark storage area, storing upgrading data in the upgrading instruction into a storage area to be upgraded, clearing the upgrading mark after the upgrading data is correctly and completely stored into the storage area to be upgraded, and finishing upgrading of a program, wherein if the upgrading data is incorrectly and/or incompletely stored into the storage area to be upgraded, the upgrading mark is not cleared.
If the upgrading flag is written into the upgrading flag storage area, the upgrading flag is valid, and if the upgrading flag is not written into the upgrading flag storage area, the upgrading flag is invalid. After it is determined that the first storage area does not have a space to store the upgrade data, the upgrade flag being updated is written into the upgrade flag storage area, and then step S308 is performed to jump to the second storage area and read the upgrade flag in the upgrade flag storage area to determine the upgrade status. If the "upgrading flag" is valid, step S309 is executed, in which the upgrade instruction is received through the second storage area, so as to store the upgrade data in the upgrade instruction into the storage area to be upgraded. After the fact that the upgrade data stored in the storage area to be upgraded is correct and complete is judged, the 'upgrading sign' in the upgrade sign storage area is cleared, and at the moment, the data in the storage area to be upgraded is updated into upgraded data, so that the upgrade of the program to be upgraded is completed. If the upgrade data is not correctly and/or incompletely stored in the memory area to be upgraded, the "being upgraded flag" is not cleared, and step S312 is performed to wait for the upgrade again.
On the basis of the above embodiment, optionally, before step S301, the method for upgrading an electronic device further includes:
Receiving an upgrade scheduling instruction, wherein the upgrade scheduling instruction at least comprises an instruction for entering an upgrade mode;
after receiving the upgrade scheduling instruction, upgrade preparation is completed.
The upgrade preparation may include switching from the normal operation mode to the upgrade mode, switching to the upgrade protocol, sending length information of upgrade data, total memory of the first storage area, currently used memory, and the like after receiving the upgrade scheduling instruction. It should be noted that, the upgrade preparation work is not limited to the above steps, and the upgrade preparation work may also include other steps, or at least some of the above steps, and the specific content of the upgrade preparation work is not limited in this embodiment.
The upgrade scheduling instruction is issued to the micro control unit MCU of the electronic device through the upper computer, or issued to the upper communication unit of the electronic device through the upper computer, and issued to the micro control unit MCU through the upper communication unit. .
After the micro control unit MCU receives the upgrade scheduling instruction and finishes upgrade preparation, upgrade ready information can be generated, so that the upper computer can inquire (or inquire through the upper communication unit) the upgrade ready information of the micro control unit MCU, and then the upgrade instruction is issued to the micro control unit MCU according to the inquired upgrade ready information. For example, when other control units are further connected to the communication bus between the upper computer and the MCU, the MCU and the other control units may complete the upgrade preparation after receiving the upgrade scheduling instruction, generate upgrade ready information, and after the MCU and the other control units can be queried by the upper computer, the upper computer may issue an upgrade instruction to the MCU and the other control units, so that the MCU and the other control units execute steps S302 to S312 in the above embodiment, to implement the upgrade of the program to be upgraded.
In an exemplary embodiment, when the instruction for entering the upgrade mode is received and it is determined that the first storage area does not have a space for storing upgrade data according to the length information of the upgrade data in the instruction for entering the upgrade mode and the current remaining available memory of the first storage area, the upgrade instruction needs to be received through the second storage area, that is, step S308 in the above embodiment needs to be executed, and the operation jumps to the second storage area. If the interruption or failure of the upgrade process of the program to be upgraded occurs after the jump to the second storage area, for example, in the process of executing step S309, the interruption or failure of the upgrade process of the program to be upgraded occurs, and the electronic device is powered down and restarted to be upgraded again, the upgrade scheduling instruction can be received again through the second storage area to complete the upgrade preparation, so that the upgrade data can be stored in the to-be-upgraded storage area through the second storage area in response to the upgrade instruction again, thereby completing the upgrade of the program to be upgraded.
According to the technical scheme, when the electronic equipment is upgraded again after the upgrade failure, the upgrade scheduling instruction can be received again, and upgrade preparation is completed, so that the program to be upgraded is upgraded. The scheme is applicable to a system for communicating with a plurality of electronic devices, if a plurality of electronic devices are upgraded at the same time, and the upgrade of one electronic device is interrupted or failed, the electronic device can receive the upgrade scheduling instruction again, upgrade preparation is completed, upgrade ready information is generated and sent to an upper computer or an upper communication unit, and accordingly the upgrade process is continued.
On the basis of the embodiment, the upgrading mark optionally further comprises a storage area jump mark, wherein the storage area jump mark is used for representing that the electronic device has received an upgrading scheduling instruction and completes upgrading preparation, and correspondingly, after the upgrading mark is written into the upgrading mark storage area and before jumping to the second storage area, the upgrading method of the electronic device further comprises the step of writing the storage area jump mark into the upgrading mark storage area.
Illustratively, a "memory region jump flag" may be used to inform the second memory region whether it is necessary to cooperate with the system to receive upgrade scheduling instructions to complete the upgrade preparation. After it is determined that the first memory area does not have a space to store the upgrade data, the "being-upgraded flag" is written to the upgrade flag memory area, and the "memory area jump flag" is written to the upgrade flag memory area (the "being-upgraded flag" may be written before the "memory area jump flag" or both may be written at the same time), step S308 is executed again after the "being-upgraded flag" and the "memory area jump flag" are both written to the upgrade flag memory area, and the jump to the second memory area is performed. Since it has been determined that the first memory area does not have a space to store the upgrade data at this time, it is necessary to receive an upgrade instruction through the second memory area, thereby storing the upgrade data in the memory area to be upgraded in response to the upgrade instruction, and the electronic device has received the upgrade scheduling instruction and completed the upgrade preparation, the "memory area jump flag" may be written into the upgrade flag memory area before step S308 is performed.
On the basis of the above embodiment, optionally, after step S308, the method for upgrading an electronic device further includes:
if the upgrading mark and the storage area skip mark are written into the upgrading mark storage area, the storage area skip mark is cleared;
if the upgrading mark is written into the upgrading mark storage area, but the storage area jump mark is cleared, the upgrading scheduling instruction is received again, and the upgrading preparation is completed.
Illustratively, if the "memory area skip flag" has been written to the upgrade flag memory area, it indicates that the "memory area skip flag" is valid, and if the "memory area skip flag" has not been written to the upgrade flag memory area, it indicates that the "memory area skip flag" is not valid. After determining that the first storage area does not have a space to store the upgrade data, step S308 in the above embodiment is performed, jumping to the second storage area, and reading the upgrade flag in the upgrade flag storage area to determine the upgrade status. If the "update flag" is valid, if the "storage area skip flag" is valid, it indicates that the electronic device has received the update scheduling instruction and completed the update preparation, and the "storage area skip flag" in the update flag storage area may be cleared, and steps S309 to S311 are continuously performed, so as to complete the update of the program to be updated.
In the case of interruption or failure of the upgrade process of the program to be upgraded, for example, after the electronic device is powered down and restarted after the last upgrade failure, whether various upgrade marks in the upgrade mark storage area are valid is detected, if the upgrade mark is valid and the storage area skip mark is invalid, the storage area skip mark is cleared, the interruption or failure of the last upgrade occurs after the first storage area is judged to have no space for storing upgrade data, an upgrade instruction is required to be received through the second storage area, and the second storage area is skipped. Therefore, the upgrade scheduling instruction can be received again through the second storage area and upgrade preparation is completed, so that upgrade data can be stored into the storage area to be upgraded through the second storage area in response to the upgrade instruction again, and upgrade of the program to be upgraded is completed.
On the basis of the above embodiments, optionally, the upgrade flag storage area includes a first sub-storage area, a second sub-storage area, and a third sub-storage area, where the first sub-storage area is used for storing an upgrade completion flag, the second sub-storage area is used for storing an upgrade-in flag, and the third sub-storage area is used for storing a storage area jump flag. The present solution stores different types of upgrade flags by setting different sub-storage areas, so that the value interval that can be stored in each sub-storage area is larger, and thus the probability of erroneous judgment of the upgrade status can be reduced, for example, if one upgrade flag is represented by a value of 0, and another upgrade flag is represented by a value of 1, then the corresponding space in the memory is changed from one upgrade flag to another upgrade flag whenever one bit is changed, and if one upgrade flag is represented by a value of 0xAA, and another upgrade flag is represented by a value of 0x55, then the probability of erroneous judgment of the upgrade status will be reduced. Alternatively, in other embodiments of the present invention, different values may be used in the upgrade flag storage area to characterize different upgrade flags. For example, different upgrade flags such as "upgrade complete flag", "in-upgrade flag", and "memory area jump flag" are characterized by different four-bit binary values, and by reading the values stored in the upgrade flag memory area, it can be determined whether each upgrade flag is valid, thereby determining the current upgrade status of the program to be upgraded.
On the basis of the above embodiments, optionally, the upgrade flag storage area may further include a fourth sub-storage area, and before jumping to the second storage area, other upgrade data attribute information related to the upgrade of the program to be upgraded, such as length information, check information, and data packet information of the upgrade data, may be stored in the fourth sub-storage area, so that the second storage area is facilitated to acquire more upgrade data attribute information.
On the basis of the above embodiments, optionally, when each upgrade flag in the upgrade flag storage area is invalid, or when any upgrade flag is not stored in the upgrade flag storage area, the storage area to be upgraded is skipped, so as to realize a secondary boot function, so that the program to be upgraded cannot normally run.
On the basis of the above embodiments, optionally, the boot area (when the program to be upgraded is an application program, the second storage area is the boot area, and when the program to be upgraded is the boot program, the storage area to be upgraded is the boot area) may also support more control functions, for example, the APP area has a function of controlling a corresponding electronic device, and the boot area may be set to have the same function as the APP area, that is, the corresponding electronic device may be controlled by the boot area. The advantage of setting like this is that under the condition such as upgrade failure, can directly control electronic equipment through the guide area to avoid waiting to upgrade program data in the APP district to be cleared up the unable operation of system that causes, thereby reduce the influence of upgrade failure to system normal operating, when electronic equipment is the electric energy conversion equipment in the photovoltaic system, this scheme helps reducing photovoltaic system's generated energy loss.
Fig. 4 is a flowchart of another method for upgrading electronic equipment according to an embodiment of the present invention. Based on the above embodiments, the present embodiment optimizes an upgrade method of an electronic device. Referring to fig. 4, the method of this embodiment specifically includes the following steps:
S401, receiving an upgrade scheduling instruction.
The upgrade scheduling instruction at least comprises an instruction for entering an upgrade mode.
S402, after receiving the upgrade scheduling instruction, completing upgrade preparation.
S403, judging whether the first storage area has a space for storing the upgrade data according to the length information of the upgrade data and the residual available memory of the first storage area.
When the program to be upgraded is an application program, the storage area to be upgraded is used for storing application program data, the second storage area is a guide area, and when the program to be upgraded is a guide program, the storage area to be upgraded is used for storing guide program data, and the second storage area is an application area.
If the first storage area has a space for storing upgrade data, step S404 is performed, and if the first storage area does not have a space for storing upgrade data, step S411 is performed.
S404, receiving an upgrade instruction through the storage area to be upgraded or the second storage area so as to store upgrade data in the upgrade instruction into the first storage area.
S405, judging whether the upgrade data received by the first storage area is correct and complete.
Specifically, after the first storage area finishes receiving the upgrade data, whether the upgrade data received by the first storage area is correct and complete is judged. If the upgrade data received by the first storage area is incorrect and/or incomplete, step S406 is performed, and if the upgrade data received by the first storage area is correct and complete, step S407 is performed.
S406, the upgrade completion flag is not written into the upgrade flag storage area, and upgrade data in the first storage area is emptied.
S407, writing the upgrade completion flag into the upgrade flag storage area.
S408, judging whether the upgrading completion flag is valid.
If the upgrade completion flag is valid, step S409 is executed, and if the upgrade completion flag is invalid, step S413 or step S415 is executed (only the case of executing step S413 is shown in the figure). If the upgrade completion flag is written into the upgrade completion flag storage area, the upgrade completion flag is valid, and if the upgrade completion flag is not written into the upgrade completion flag storage area, or the upgrade completion flag is cleared, the upgrade completion flag is invalid.
S409, replacing the program data to be upgraded in the storage area to be upgraded by the upgrade data stored in the first storage area through the second storage area, and clearing the upgrade completion mark after the data in the storage area to be upgraded has been replaced with the upgrade data stored in the first storage area.
S410, jumping back to the storage area to be upgraded from the second storage area to finish upgrading of the program to be upgraded.
S411, writing the upgrading mark and the memory area jump mark into the upgrading mark memory area.
S412, jumping to the second storage area.
S413, judging whether the upgrading mark is valid.
If the upgrade flag is valid, step S414 is performed, and if the upgrade flag is invalid, step S415 is performed. Wherein, if the upgrade flag storage area is written with the upgrade flag, the upgrade flag is valid, and if the upgrade flag storage area is not written with the upgrade flag, or the upgrade flag is cleared, the upgrade flag is invalid.
S414, responding to the upgrade instruction through the second storage area, firstly erasing the data in the storage area to be upgraded, then storing the upgrade data into the storage area to be upgraded, and after the storage area to be upgraded stores the upgrade data, clearing the upgrading mark.
S415, jumping to the storage area to be upgraded.
The method for upgrading the electronic equipment when the upgrading mark is valid further comprises the following steps:
s416, judging whether the storage area jump mark is valid.
If the memory area jump flag is valid, step S417 is performed, and if the memory area jump flag is invalid, step S418 is performed. If the upgrade mark storage area is written with the storage area skip mark, the storage area skip mark is valid, and if the upgrade mark storage area is not written with the storage area skip mark or the storage area skip mark is cleared, the storage area skip mark is invalid.
S417, clearing the storage area jump mark.
S418, re-receiving the upgrade scheduling instruction through the second storage area to finish upgrade preparation.
For example, in the case where the "upgrade flag" is valid, if the "memory area skip flag" is valid, it indicates that the electronic device has received the upgrade scheduling instruction and completed the upgrade preparation, the "memory area skip flag" in the upgrade flag memory area may be cleared, that is, after the completion of step S417 is performed, step S414 and step S410 are continuously performed, thereby completing the upgrade of the program to be upgraded.
Under the conditions of interruption or failure of the upgrading process of the program to be upgraded, for example, after the electronic equipment is powered down and restarted after the last upgrading failure, whether various upgrading marks in the upgrading mark storage area are valid or not is detected, if the upgrading mark is valid and the storage area skip mark is invalid, the storage area skip mark is cleared, the interruption or failure of the last upgrading occurs after the first storage area is judged to have no space for storing upgrading data, an upgrading instruction is needed to be received through the second storage area, and the program to be upgraded is jumped to the second storage area. Therefore, the upgrade scheduling instruction can be received again through the second storage area to complete upgrade preparation, so that the upgrade of the program to be upgraded is completed. For example, after the execution of the completion step S418, the execution of step S414 and step S410 is continued, thereby completing the upgrade of the program to be upgraded.
The technical scheme of the embodiment of the invention is suitable for upgrading the program to be upgraded in the MCU of the electronic equipment, and the program to be upgraded can be an application program or a guide program. When the first storage area has a space for storing upgrade data, an upgrade instruction is received through the storage area to be upgraded or the second storage area, so that the upgrade data in the upgrade instruction is stored in the first storage area, and the upgrade program to be upgraded is upgraded, when the first storage area does not have the space for storing the upgrade data, the upgrade instruction is received through the second storage area, so that the upgrade data in the upgrade instruction is stored in the storage area to be upgraded, and the self-adaptive adjustment of the receiving mode of the upgrade data according to the memory space required by the upgrade data is realized. For the electronic equipment, the memory space occupied by the programs to be upgraded at different stages is different, the scheme is beneficial to meeting the upgrade data receiving requirements of the programs to be upgraded at different stages in the electronic equipment, the memory cost of the system is not required to be increased, the reliability of the programs to be upgraded is improved, and the influence of the upgrading process on the normal operation of the equipment is reduced.
