Abstract
The present invention relates to a kind of Aerial Electronic Equipment application program curing method, the Aerial Electronic Equipment has FLASH；The FLASH's is divided into：Starting guidance memory block, the application program storage area A and application program store the area B；Starting memory block is used to be resident the minimum Bootloader of Aerial Electronic Equipment computer module, and the application program storage area A and the application program storage area B are used to storage application program.Present invention seek to address that in upgrading solidification process, when encountering the accidents such as burst power-off, the problem of causing Module Fail to need depot repair；It is dedicated to that the computer module of Aerial Electronic Equipment is greatly protected not lead to computer module disabler because of corrupted data in upgrading solidification process, influences the normal work of Aerial Electronic Equipment.
Description
Technical field
The present invention relates to avionics system domain design technology, in particular to Aerial Electronic Equipment application system upgrading is cured
Design method.
Background technique
Avionics system field at home, the computer module of Aerial Electronic Equipment are commonly provided with unique starting memory module
(FLASH), in the module, equipment starting also starts from the unique address of the module for the application software solidification of computer module,
System upgrade solidify when, equipment wipes the file data on unique memory module (FLASH) first, then re-write to
The data file of upgrading.When encountering the burst loss of power accident, if in the erasable data procedures upgraded, the computer module
Since the data of memory module are destroyed, starting ability is lost, which cannot normally start work, module damage,
Extreme influence mission requirements.
The present invention is by being designed as multiple storages for unique starting memory module (FLASH) of Aerial Electronic Equipment computer module
Module (FLASH) guarantees that appliance applications escalation process does not destroy current Operational Zone (FLASH) data；Again by solidifying
Setting starting mark after the completion, after guaranteeing that upgrading solidifies successfully, equipment can carry out starting operation from newest data field, protect simultaneously
It when card upgrading solidification failure, can be started from legacy data area, solve to damage because of burst power-off or device upgrade failure
The problem of bad equipment.
Summary of the invention
Goal of the invention
Present invention seek to address that when encountering the accidents such as burst power-off, Module Fail is caused to need in upgrading solidification process
The problem of depot repair；It is dedicated to greatly protecting the computer module of Aerial Electronic Equipment in upgrading solidification process not due to corrupted data
Lead to computer module disabler, influences the normal work of Aerial Electronic Equipment.
Technical solution：
A kind of Aerial Electronic Equipment application program curing method is provided, the Aerial Electronic Equipment has FLASH；The FLASH's
It is divided into：Starting guidance memory block, the application program storage area A and application program store the area B；Starting memory block is for being resident avionics
The minimum Bootloader of equipment computer module, the application program storage area A and the application program storage area B are used to store
Application program；
End byte address, the application program storage area A initial address and application program in starting guidance memory block store B
Area's initial address setting starting mark, computer module of the mark for indicating avionics system is stored from application program
The starting of the area A, or start from the application program storage area B；When avionics system starts from the application program storage area A, application program
The area A is stored as starting memory block, application program stores the area B and is used as to programming memory block, when avionics system is deposited from application program
When storing up the starting of the area B, application program stores the area B as starting memory block, and application program stores the area A and is used as to programming memory block；
When executing the solidification of Aerial Electronic Equipment application program, is identified according to starting determine Aerial Electronic Equipment from application program first
It stores the area A or the application program storage area B and starts application program, complete application program solidification in programming memory block later, solidifying
After success, modification starting mark is so that starting memory block and programming memory block exchange；If starting mark is not modified in solidification failure
Know.
This curing method realizes the replacement of startup file dystopy, and programming process does not destroy the data for being currently up position, even if
Solidification failure, nor affects on equipment and starts from original position, establish safe curing environment.
Beneficial effect
During the present invention solves Aerial Electronic Equipment function upgrading, lead to module because unpredictable situation upgrades failure
The problem of failure needs depot repair；On the basis of the application above method, more security upgrading methods can be derived, change is worked as
Preceding single upgrade mode enriches the maintenance service of airborne Aerial Electronic Equipment, reduces maintenance cost.
Specific embodiment
For a better understanding of the present invention, below by embodiment, invention is further described in detail.
A kind of Aerial Electronic Equipment application program curing method is provided, the Aerial Electronic Equipment has FLASH；The FLASH's
It is divided into：Starting guidance memory block, the application program storage area A and application program store the area B；Starting memory block is for being resident avionics
The minimum Bootloader of equipment computer module, the application program storage area A and the application program storage area B are used to store
Application program；
End byte address, the application program storage area A initial address and application program in starting guidance memory block store B
Area's initial address setting starting mark, computer module of the mark for indicating avionics system is stored from application program
The starting of the area A, or start from the application program storage area B；When avionics system starts from the application program storage area A, application program
The area A is stored as starting memory block, application program stores the area B and is used as to programming memory block, when avionics system is deposited from application program
When storing up the starting of the area B, application program stores the area B as starting memory block, and application program stores the area A and is used as to programming memory block；
When executing the solidification of Aerial Electronic Equipment application program, is identified according to starting determine Aerial Electronic Equipment from application program first
It stores the area A or the application program storage area B and starts application program, complete application program solidification in programming memory block later, solidifying
After success, modification starting mark is so that starting memory block and programming memory block exchange；If starting mark is not modified in solidification failure
Know.
