Abstract
The invention discloses a method for optimizing a VxWorks system startup process by using an ARJ compressed file. A redundant backup of a VxWorks system image is provided by using the ARJ compressed file; a decompression function is implanted into a guidance code; if the condition that a VxWorks image file cannot be normally loaded is found out when a system startup guide program runs, the decompression function is called to generate an available VxWorks image file again and then the system is restarted, so that the system image can be normally loaded. The method has the beneficial technical effects that the method for optimizing the VxWorks system startup process by using the ARJ compressed file is provided, the VxWorks image file can be automatically restored without human intervention when damaged, the phenomenon that equipment cannot be started due to the damage to the VxWorks image file can be avoided and the reliability of the equipment is improved. According to the method, the redundant backup is provided by using the ARJ compressed file and occupation of a storage space of a FLASH is small.
Description
Technical field
The invention belongs to the VxWorks system map file of military communication technical field, more particularly, to vxworks operating system
Booting sequence.
Background technology
In military communication technical field, vxworks operating system is used widely.When system starts, VxWorks
The normal startup of system image is particularly important.VxWorks image file typically leaves in the FLASH of EM equipment module, due to army
The reasons such as the residing harsh and unforgiving environments of thing communication, it may occur that the phenomenon of VxWorks image file damage, lead to EM equipment module cannot open
Dynamic.Additionally, the memory space very little of FLASH is it is impossible to by the way of direct Backup Images file.
In general, vxworks operating system includes guidance code and system image.Wherein guidance code is VxWorks
The BOOTROM that under operating system, compilation of source code generates, Main Function is the minimum hardware cell of initialization, can to load
The system image of vxworks operating system.In the initial designs of vxworks operating system, there is provided start configuration parameter
(bootline), after system electrification startup, that is, execute the guidance code of vxworks operating system, read and parse this startup
After configuration parameter, carry out startup configuration according to starting configuration parameter, then according to start configuration loading vxworks operating system be
System image, thus start vxworks operating system.
ARJ is one of the most widely used compressed software nineties.It is low to system performance requirements, and compression ratio is higher, pressure
Contracting decompression speed is fast.Additionally, free source code is provided on internet, can easily embed it in various systems
Go.
Content of the invention
The invention discloses a kind of method that utilization ARJ compressed file optimizes VxWorks system Booting sequence, using ARJ
Compressed file provides the redundancy backup of VxWorks system image, implants ARJ decompressing function in guidance code.When system opens
When dynamic bootstrap is run, if find VxWorks image file cannot normal load, call ARJ decompressing function again to give birth to
Become available VxWorks image file, then restart system, you can normal load system image.The technical side that the present invention adopts
Case is as follows：
1) ARJ decompressing function is transplanted in VxWorks development environment；
2) improve the boot flow of guidance code, guidance code adds ARJ compressed file verifying function；
3) improve guidance code boot flow, when VxWorks image file cannot normal load when, call ARJ decompression work(
Available VxWorks image file can be regenerated；
4) improve the boot flow of guidance code, after decompression generates VxWorks image file success, automatically restart system；
5) by the BOOTROM programming after improving in the EPROM of EM equipment module；
6) in EM equipment module normal work, the ARJ compressed file of VxWorks system image is uploaded to EM equipment module
In FLASH.
The method have the benefit that：Provide a kind of utilization ARJ compressed file and optimize VxWorks system Booting sequence
Method, can automatically recover without human intervention when VxWorks image file damages, be avoided that due to VxWorks image file
Destroy the phenomenon leading to equipment cannot start, improve the reliability of equipment.Method adopts ARJ compressed file as backup, right
The memory space of FLASH takies little.
Brief description
Fig. 1, the BOOTROM boot flow of initial designs；
Fig. 2, the BOOTROM boot flow of Curve guide impeller.
Specific embodiment
This utilizes the method that ARJ compressed file optimizes VxWorks system Booting sequence as depicted in figs. 1 and 2, and its feature exists
In comprising the steps of：
1) ARJ decompressing function is transplanted in VxWorks development environment；
2) improve the boot flow of guidance code, guidance code adds ARJ compressed file verifying function；
3) improve guidance code boot flow, when VxWorks image file cannot normal load when, call ARJ decompression work(
Can, regenerate available VxWorks image file；
4) improve the boot flow of guidance code, after the VxWorks image file that decompression generates can use, automatically restart system；
5) by the BOOTROM programming after improving in the EPROM of EM equipment module；
6) in EM equipment module normal work, the ARJ compressed file of VxWorks system image is uploaded to EM equipment module
In FLASH.
Step 2) in also include：Need verification ARJ compressed file whether there is, and whether there is in verification compressed file
VxWorks image file.
Step 3) in also include：Should decompress again after the VxWorks image file of first deletion error, or adopt in decompression
Take from the mode of dynamic covering, file path should keep constant.
The above, the only present invention preferably specific embodiment, but protection scope of the present invention is not limited thereto,
Any those familiar with the art the invention discloses technical scope in, technology according to the present invention scheme and its
Inventive concept equivalent or change in addition, all should be included within the scope of the present invention.
