Abstract
The present invention proposes a method for automatically loading single board versions. The method comprises the following steps: (1) before powered on, a single board is normally connected with a version machine, and the connection is always kept normal when the single board runs; (2) the single board is powered on, and after a bootstrap program finishes running, version files at the flash point of a flash memory are validly checked before the version files directly jumping to the flash point of the flash memory run; (3) if the validity check is not passed, the course of loading versions from the version machine is executed; if the versions are successfully loaded or the validity check is passed, the version files jump to a version file point to continuously run. The present invention directly copies versions to a version machine; if version files on a single board is detected not to accord with version files on the version machine after the single board is powered on, the version files on the version machine are automatically loaded to run without the need of manual intervention.
Description
Technical field
The present invention relates to computing machine and communication field, specifically, is a kind of method of loading version when realizing single board starting automatically.
Background technology
The version of veneer is meant the executable file of finishing the veneer predetermined function, also claims the version file of veneer.The version machine is meant the main frame of the version that stores veneer.
Generally do not have hard disk on the veneer, the version file of veneer resides on the flash memory Flash of veneer usually, and the version file on the Flash gets on by the manual loading of manual intervention.Suppose to be mounted with version file on the Flash of veneer, Board Power up starts according to following steps: (1) veneer at first moves guiding (the being boot) program that is stored on the ROM, boot program run success; (2) memory address that directly jumps to version file begins the place and continues operation, and so far the start-up course of veneer finishes, and veneer formally begins to finish a series of predetermined function.There is following shortcoming in the traditional single-board starting process of above-mentioned this:
Each version loads and must manual intervention finish by hand, and each in other words version is changed or edition upgrading all needs manual finishing, and can not carry out automatically;
If exist the polylith veneer of same type to need load application version, need carry out manual loading one by one, can not disposablely finish automatically;
If the version file on the Flash is destroyed, its corresponding measures can not be checked out and be made to above-mentioned start-up course, still jump to the version file place by normal flow and bring into operation, cause veneer normally not start up, thereby influenced the stability of total system.
At present, do not retrieve the open source literature of discussing and addressing the above problem as yet.
Summary of the invention
The technical problem to be solved in the present invention is that version loads during at single board starting, and a kind of method of single board edition automatic loading is provided.Above-mentioned shortcoming when the present invention can effectively solve traditional single board starting makes that the single board edition loading process is oversimplified, robotization, and improves the stability and the robustness of total system greatly.
Of the present invention being achieved in that
(1) before the Board Power up, be connected one group of veneer normal with the version machine and to remain this connection in the veneer operational process normal;
(2) Board Power up behind the boot end of run, before the version file that directly jumps to flash memory Flash place brings into operation, carries out validity check to the version file at flash memory Flash place;
(3) if validity check is not passed through, then carry out the process of loading version from the version machine; If version loads success or validity check is passed through, then jump to the version file place and continue operation, the version start-up course is finished smoothly.
Compare with traditional single-board starting process, the present invention has following advantage:
Each version loads (as version updating or edition upgrading), directly version is copied on this machine of plate, if the version file and the version file on the version machine that detect behind the Board Power up on the veneer are inconsistent, the version file operation on the load application version machine must not finished automatically in manual intervention automatically.
Give the polylith single-board replacement version of same type if desired, directly the version file with such veneer is stored on the version machine, and the polylith veneer can load same version simultaneously automatically and start operation, must manual intervention not load one by one.
If the version file on the Flash is destroyed, above-mentioned algorithm can detect this mistake automatically, and the operation of the version on the load application version machine again, has avoided because this mistake causes the serious consequence that veneer can not normally start.
Characteristics of the present invention are succinctly feasible, are easy to realize.

Fig. 3 is the single board edition automatic loading algorithm flow chart.
Embodiment
Below in conjunction with accompanying drawing, the embodiment of single board edition automatic loading method of the present invention is described in detail.
Fig. 1 is the memory address space distribution diagram of veneer, it has provided the internal storage structure (comprising ROM, RAM, FLASH) of general veneer, mainly be in order to illustrate that boot program and version file are stored in the different address spaces in the internal memory of single board respectively, as: the boot procedure stores is in ROM, version file is stored among the FLASH, behind the Board Power up, boot program on the veneer ROM is at first moved, if move successfully, the version file place that directly jumps on the FLASH brings into operation, and traditional single-board starting process finishes.
Fig. 2 is the single board edition automatic loading layout of equipment, in order to realize single board edition automatic loading, veneer must be linked to each other with the version machine, and the connected mode of veneer and version machine can be supported TCP/IP, HDLC as the case may be.If polytype polylith veneer is articulated on the same version machine, should store the version file of each type veneer correspondence on the version machine.Veneer 1_1, veneer 1_2, veneer 1_n represent the polylith veneer of same type among Fig. 2, and the version machine can be simultaneously loads automatically to one group polylith veneer wherein.Certainly, the minimum number of one group of veneer can be one.
Fig. 3 is single board edition automatic loading realization flow figure, specifically describes as follows:
Step1: beginning links to each other veneer with the version machine;
Step 2: Board Power up, boot program run;
Step 3:boot program must check before the version file place that jumps on the Flash that is: (1) checks whether version file exists to the version file on the Flash, if there is no, carried out Step4; (2) check whether version file is correct,, carry out Step4 if incorrect; (3) check whether the version file on the veneer is consistent with the version file on the version machine,, carry out step4 if inconsistent; Otherwise change step5;
Step4: carry out the process that veneer loads version file from the version machine,, change step6 if load successfully;
Step5; If version loads failure, keep a diary or alarm, prompting version error information, the version start-up course is returned;
Step6: the version file place that veneer boot program jumps to Flash brings into operation, and the version start-up course is finished.
The above-mentioned automatic loading version method according to the present invention can make that the version file of polylith veneer operation of same type is in full accord.
