Mutually combination.
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings, but not as limiting to the invention.
Technical scheme includes the method for a upgrade-system kernel image.
As shown in figure 1, a kind of method of upgrade-system kernel image, applied to embedded device, comprises the following steps：
Step S1, a random memory unit is provided, to load a source file；
Step S2, one converting unit is provided, to by a system partition holding in being mapped as a mesh in random memory unit
Mark file；
Step S3, instructed using system copies and source file is copied to file destination；
Step S4, file destination is converted to matching system partition holding form, and writing system storage point by converting unit
Area.
In above-mentioned technical proposal, source file is loaded by random memory unit, and system is stored by converting unit
Subregion is mapped as file destination in random memory unit, and it is laggard that source file is copied into file destination by system copies order
File destination is converted into matching system partition holding form by one step by converting unit, and file destination writing system is deposited
Subregion is stored up, it is achieved thereby that need not program, the operation of upgrade-system kernel image, operation are completed using only system copies order
It is simple and convenient.
In a kind of preferably embodiment, in step S1, there is provided a host computer, for source file to be transmitted to depositing at random
Storage unit.In further preferred embodiment, host computer can be computer.
