Embodiment
Below in conjunction with accompanying drawing, the embodiment of method, device and the embedded device of the program upgrade that the embodiment of the invention is provided is at length explained.
The programme upgrade method that the embodiment of the invention provides can be applied to the to upgrade embedded OS of a plurality of embedded devices can also be applied to the multiple application program of upgrading hardware platform, does not do qualification at this.
Particularly, the method for a kind of program upgrade that the embodiment of the invention provides, as shown in Figure 1, may further comprise the steps:
S101, operation boot;
S102, the master on needing the hardware platform of ROMPaq in the loading procedure reflection bag use program image;
Whether S103, definite master who loads are applicable to hardware platform with program image; If, execution in step S104; If not, execution in step S105;
S104, on hardware platform this main program of using of operation;
S105, confirm whether there is alternative program image in the program image bag; If there is execution in step S106; If there is not execution in step S108;
S106, on hardware platform, load each alternative program image successively, be applicable to hardware platform until the alternative program image of confirming current loading;
The alternative program of S107, the current loading of operation on hardware platform;
S108, process ends.
Particularly; The program image bag that uses in the said method that the embodiment of the invention provides; Can obtain in the following manner: before embedded product is upgraded, when the program image that need upgrade when a plurality of hardware platforms is incomplete same, in the program image that a plurality of hardware platforms need be upgraded, chooses a program image and use program image as main; The alternative program image of other conduct; To lead with program image and at least one alternative program image packing generator program reflection bag, the program image bag for packing after generating shown in Figure 2 comprises that a master is with program image and a plurality of alternative program image; Perhaps; When the program image that need upgrade when a plurality of hardware platforms is identical; Can the program image that a plurality of hardware platforms need be upgraded be used program image as the master; And will lead with program image packing generator program reflection bag, so just can use this program image bag is a plurality of hardware platform ROMPaqs.
In the method that the embodiment of the invention provides, a plurality of program images of a plurality of hardware platforms are merged into a program image bag, can reduce the software publishing number of times of manufacturer; Make things convenient for manufacturer and user software version management to equipment; And, use same program image bag a plurality of hardware platforms of upgrading, can reduce the complexity of upgrading; And the probability of the use mistake of upgrade software in the time of also can reducing a plurality of equipment and need upgrade improves upgrading efficient.
In the specific implementation; Preferably, the master in the program image bag is with program image and the equal processed compressed of alternative program image, and a plurality of alternative program image can be attached to main with after the program image with the mode of additional compression data successively; Like this, also be convenient to existing hardware platform compatible.
The concrete implementation of each step of the said method that provides in the face of the embodiment of the invention is down carried out detailed explanation, wherein, is attached to the main program image structure afterwards of using with the alternative program image in the program image bag with the mode of additional compression data and is the example explanation.
Particularly, confirm among the step S103 of said method whether the master who loads is applicable to hardware platform with program image, can realize through following manner:
At first, boot reads the sign of hardware platform, for example the model of product or numbering;
Then, boot is judged the sign that whether has this hardware platform in the main product mark tabulation with program image, if confirm that this master is applicable to this hardware platform with program image.
Whether the master of above-mentioned definite loading is applicable to that with program image the detailed process of current hardware platform just illustrates, and when practical operation, can also realize through other modes, does not limit at this.
