Description
Technical field
The present invention relates to embedded chip software upgrading technical field, especially a kind of multiple single chip microcomputer program upgrade system and its
Method.
Background technique
OTA technology refers to be programmed during user program operation.OTA technology is will be in single-chip microcontroller from structure
The memory space of storage user program is divided into two memory blocks in flash storage, stores when running in a storage region
User program when, the user program stored in another storage region can be reprogramed, then, be reruned again
The user program on memory bank after programming.
Existing most of OTA upgrading scheme is designed both for individual node (a node i.e. single-chip microcontroller),
For distributed system, there are multiple single-chip microcontroller nodes, if the scheme upgraded one by one using individual node, multiple nodes
It is equal to the summation of each node update time the time required to program upgrading, therefore it is very low to upgrade efficiency.
The features such as single-chip microcontroller is high, small in size with its integrated level, function is strong, low in energy consumption, high reliablity, is widely applied to
In industrial equipment or even inside a equipment, multiple single-chip microcontrollers may be used, and for executing different functions.
In the prior art, to the online upgrading of single-chip microcontroller, mainly pass through the online upgrading function in boot loader
Code completes, reset single-chip microcontroller from application program and runs after line upgrade function, will be received by the function code
Program file data cover to be updated is written to for storing the region of application data in the area program Flash, to reach
Update the purpose of SCM program.
With the rapid development of super large-scale integration, the processing speed and processing capacity of chip are continuously improved.Monolithic
The machine advantage high by its small in size, light weight, cost performance, is got in fields such as Industry Control, network communication, aerospaces
To be more widely applied.Due to single-chip microcontroller it is generally necessary to which the user program for executing specific function is written according to practical application, and this
A little user programs can be updated with the difference of actual conditions or the continuous popularization needs of application, and therefore, it is necessary to often right
User program in single-chip microcontroller is upgraded, and updated user program is reloaded, and is enabled the system to according to newest journey
Sequence is handled.
When single-chip microcontroller upgrades, loading procedure is run, the new user program after upgrading is written in the OTA of single-chip microcontroller, is replaced
Change original subscriber's program.Then, single-chip microcontroller is restarted, and runs the new user program in OTA.To guarantee that single-chip microcontroller normally upgrades load journey
Sequence is stored in the OTA of single-chip microcontroller, and when use calls in memory operation from OTA.Since loading procedure only upgrades in single-chip microcontroller
When use, but since it is remained stored in OTA, occupy OTA memory space, for this single-chip microcontroller extremely limited for OTA,
Cause the serious waste of resource.
Nowadays technology innovation is regenerated rapidly, and industry and consumer electronics generally use single-chip microcontroller as master controller, and singly
The program of piece machine generally requires compounding technique and updates and carry out software upgrading.Traditional scm software upgrades to chip programming
Mode, which is inconvenient, and especially product reaches user by sale and on hand, then by programming mode upgraded,
Bring huge cost of labor.
As technology develops, some single-chip microcontrollers carry out software liter in such a way that network carries out OTA (Over the Air)
Grade, which greatly reduces the cost that software upgrading is carried out for single-chip microcontroller, easy to operate.But OTA is often just for single
Single-chip microcontroller carries out software upgrading, and the system for coping with multiple single chip microcomputer can then have certain problems.
The shortcomings that for above-mentioned background, proposes and designs a kind of multiple single chip microcomputer program upgrade system, taken into account software upgrading
Convenient degree and software upgrading cost, while there is certain software privacy, using scalability.
