Wherein, startup program, that is, above-mentioned is used to control the program of upgrading, and interrupt vector table be also need to be upgraded it is interiorHold.But scatter-loading file technology is merely capable of dividing startup program content and user program content, startup programIn content, the division of startup program and interrupt vector table really be cannot achieve.Therefore single-chip microcontroller operational process is utilized in this programmeIt realizes interrupt vector table and startup program division of teaching contents, in single-chip microcontroller starting, by the interrupt vector in startup program contentTable duplication is a to arrive interrupt vector table address, at this point, just having two parts interrupt vector table in single-chip microcontroller, portion is to be located at startingInterrupt vector table in contents of program, portion is the interrupt vector table positioned at interrupt vector table address, when being upgradedUpgraded using the disconnected vector table of interrupt vector table address centering.
Carrying out upgrading to the interrupt vector table of interrupt vector table address will cause another question, that is, deposit in single-chip microcontrollerIn new version and two interrupt vector tables of legacy version, if still starting legacy version interrupt vector table when operation, upgrading is invalid, isThis, in a specific embodiment, the starting single-chip microcontroller, so that the single-chip microcontroller answers the interrupt vector tableAfter system to default interrupt vector table address, further includes:
The start bit that interrupt vector table is arranged is set to the default interrupt vector table address.In the present solution, modification is interruptedThe starting address of vector table starts interrupt vector table from startup program content for original, is revised as from interrupt vector tableLocation starts interrupt vector table, thereby may be ensured that the interrupt vector table of starting is the interrupt vector table of latest edition, ensure thatThe validity of upgrading.
S103, is burned onto first address for the startup program content, and the user program content is burned onto pre-set userProgram address.
It, can will be different specifically, after the startup program content in target program is separated with user program contentContent is burned onto the different address space of single-chip microcontroller.
Upgraded version contents of program is transmitted to default updated contents memory space by S104.
When needing to upgrade the user program of existing operation, it is necessary first to by the user program of upgraded version, i.e. meshMark user program is burned onto single-chip microcontroller.
In a specific embodiment, described that upgraded version contents of program is transmitted to default updated contents storage skyBetween, comprising:
By first updated contents memory block of the user program content transmission of the upgraded version into the single-chip microcontroller；
The interrupt vector table of the upgraded version is transmitted to the second updated contents memory block in the single-chip microcontroller.
It should be noted that upgraded version program can both be stored in external memory space, single-chip microcontroller can also be stored inIt is internal.In the present solution, in order to which two memory blocks will be marked off inside single-chip microcontroller, that is, the first updated contents memory block and secondUpdated contents memory block, by the user program content transmission of upgraded version to the first updated contents memory block, by upgraded versionInterrupt vector table is transmitted to the second updated contents memory block in single-chip microcontroller to be made to upgrade without additionally increasing storage equipmentProcess is easier.
S105, using the startup program content in the single-chip microcontroller with the upgraded version contents of program to the useFamily contents of program is upgraded with the part to be upgraded in the startup program content.
Current user program content and startup program content to be upgraded are covered using single-chip microcontroller control upgraded version programPart to be upgraded, i.e. interrupt vector table are interrupted, the upgrading of user program can be completed.
In a specific embodiment, the startup program content using in the single-chip microcontroller and the literGrade version program content upgrades the user program content and the part to be upgraded in the startup program content, wrapsIt includes:
Upgrading mark is sent to the preset configuration conservation zone of the single-chip microcontroller, so that the single-chip microcontroller detects described presetAfter configuring the upgrading mark in conservation zone, by the user program content update to target user's contents of program.
It is identified in the present solution, configuring conservation zone for storing upgrading, when needing single-chip microcontroller update user program content,Upgrading mark, which is sent, after single-chip microcontroller detects the upgrading mark of configuration conservation zone to configuration conservation zone executes the operation of upgrading.In above-mentioned specific embodiment, i.e., the user program content of the upgraded version of the first updated contents memory block is copied into applicationThe interrupt vector table content of the upgraded version of second updated contents memory block is copied to interrupt vector table area by program area.
It can be seen that a kind of burning program method provided by the embodiments of the present application, both may include in a target programStartup program content includes user program content again, before carrying out burning, utilizes presetting based on scatter-loading file technologyCompilation tool by target program startup program content and user program content be compiled into different operation time domains respectively, thusTwo kinds of contents in one target program can be separated, it is empty that different contents can be burned onto different addresses in burningBetween.Realizing one target program of maintenance also can be realized the remote upgrade of single-chip microcontroller.
