Abstract
The invention discloses the methods of BOOT in upgrading single-chip microcontroller memory a kind of, it realizes and is not necessarily to the tedious steps such as emulator, unpacking also scalable bottom BOOT, and upgrade corrupt data or upgrading interruption can also recall original state, keep bottom BOOT upgrading more convenient, it is more quick, reduce cost.
Description
Technical field
The invention belongs to electronic fields, and in particular to a method of BOOT in upgrading single-chip microcontroller memory.
Background technique
Under normal circumstances, be stored in the BOOT inside single-chip microcontroller before factory will burning complete, and fix one piece and deposit
Storage area domain, but if need to modify BOOT in the case where product has dispatched from the factory BOOT existing defects or demand changes
Just become abnormal cumbersome, common practices is that unpacking is needed to pass through emulator burning BOOT again, but this to the artificial mouth of single-chip microcontroller
Belt transect comes troublesome unpacking, the dedicated emulated device of purchase, the dedicated exploitation software of installation, is not easy to realize.
Summary of the invention
Goal of the invention: the technical problem to be solved in the present invention, the logic upgraded first are write by BOOT, upgrading
The response of instruction, the erasing of flash, the burning of flash content, completeness check are realized by code in BOOT, to be upgraded
BOOT must run this part logic in BOOT as a big difficulty, and guarantee that success rate for upgrading also becomes a big difficulty, lead to
It crosses and solves the above problems, to realize without the tedious steps such as emulator, unpacking also scalable bottom BOOT, upgrade bottom BOOT
It is more convenient, more fast, reduce cost.
Technical solution: a kind of method upgrading BOOT in single-chip microcontroller memory of the present invention, the upgrading single-chip microcontroller
The method and step of BOOT is as follows in memory:
A, host computer and single-chip microcontroller are established into data connection；
B, host computer sends flash erasing instruction, in single-chip microcontroller application program first by the content in the region BOOT copy to the area RAM with
The area FLASHA, the entrance function for then jumping to ram region BOOT execute logic in BOOT, and BOOT directly will be in the region BOOT
Hold erasing；
C, host computer sends flash content, and BOOT is by the content burning of corresponding position into flash；
D, host computer sends upgrading halt instruction, and BOOT carries out completeness check to institute's burning region, will be former if not passing through
The BOOT in the area FLASHA is restored to the area BOOT, resets if passing through, runs new BOOT.
Further, in the execution upgrading single-chip microcontroller memory when method of BOOT, it is necessary to assure MCU is at any time
There is the complete code of a BOOT in section.
Further, after the loss of data, recovery routine is carried out by unpacking.
Further, if occurring data entanglement in the bus of the host computer and single-chip microcontroller, there is imperfect situation in BOOT
A BOOT can be traced back to.
Further, if described power off in escalation process, restart the rear first step and check BOOT integrality, if not
It is complete to execute back tracking operation recovery BOOT.
The utility model has the advantages that present invention discloses it is a kind of upgrading single-chip microcontroller memory in BOOT method, realize without emulator,
The tedious steps such as unpacking also scalable bottom BOOT, and upgrade corrupt data or upgrading is interrupted can also recall original state, make
Bottom BOOT upgrading is more convenient, more fast, reduces cost.
Specific embodiment
A method of BOOT in upgrading single-chip microcontroller memory, the method and step for upgrading BOOT in single-chip microcontroller memory
It is as follows:
A, host computer and single-chip microcontroller are established into data connection；
B, host computer sends flash erasing instruction, in single-chip microcontroller application program first by the content in the region BOOT copy to the area RAM with
The area FLASHA, the entrance function for then jumping to ram region BOOT execute logic in BOOT, and BOOT directly will be in the region BOOT
Hold erasing；
C, host computer sends flash content, and BOOT is by the content burning of corresponding position into flash；
D, host computer sends upgrading halt instruction, and BOOT carries out completeness check to institute's burning region, will be former if not passing through
The BOOT in the area FLASHA is restored to the area BOOT, resets if passing through, runs new BOOT.
It is additionally provided with function in the method:
In this example, in the execution upgrading single-chip microcontroller memory when method of BOOT, it is necessary to assure MCU is at any time in section
There is the complete code of a BOOT.
In this example, after the loss of data, recovery routine is carried out by unpacking, unpacking operation refers to for monolithic machine burning
The not exposed product of record mouth must operate in this way.
In this example, if occurring data entanglement in the bus, imperfect situation, which occurs, in BOOT can trace back to one
BOOT。
In this example, if described power off in escalation process, restarts the rear first step and check BOOT integrality, if not
It is complete to execute back tracking operation recovery BOOT.
Advantages of the present invention: it realizes without tedious steps also scalable bottom BOOT, and ascending series such as emulator, unpackings
Original state can also be recalled by interrupting according to error or upgrading, kept bottom BOOT upgrading more convenient, more fast, reduced cost.
The above described is only a preferred embodiment of the present invention, be not intended to limit the present invention in any form, though
So the present invention has been disclosed as a preferred embodiment, and however, it is not intended to limit the invention, any technology people for being familiar with this profession
Member, without departing from the scope of the present invention, when the technology contents using the disclosure above make a little change or modification
For the equivalent embodiment of equivalent variations, but anything that does not depart from the technical scheme of the invention content, according to the technical essence of the invention
Any simple modification, equivalent change and modification to the above embodiments, all of which are still within the scope of the technical scheme of the invention.
