Cloth is used as production, so as to improve the efficiency and reliability of making.
To achieve these goals, the invention provides a kind of NOR FLASH recordable paper preparation methods, the making side
Method includes：When software is issued, NOR FLASH recordable papers are automatically generated based on software program data and initialization data, including
Following steps：
Step 1：Initial NOR FLASH recordable papers are created, the initial NOR FLASH recordable papers are an empty file；
Step 2：Judge that partition profile whether there is untreated row, if it does not exist, then step 7 is jumped to, if
In the presence of using the untreated row of front position as current untreated row, jumping to step 3；
Step 3：Whether the current untreated row for judging partition profile is explanatory notes row or blank line, if it is,
Step 2 is jumped to, if it is not, jumping to step 4；
Step 4：The current untreated row of parsing jumps to step 5 to obtain partition size and subregion source file path；
Step 5：Subregion source file is added to recordable paper afterbody, jumps to step 6；
Step 6：With subregion source file size and the difference of partition size, make size of data and be difference and all filled out with 0xFF
The filling file filled, filling file is added to the afterbody of recordable paper, jumps to step 2；
Step 7：Terminate；
Wherein, partition profile is divided one kind by pre-production, each hand-manipulating of needle of its non-explanatory notes row or blank line
Area, it is made up of per a line partition size and subregion source file path.
Alternatively, in the preparation method：Divisional type includes BOOT boot partitions, environmental variance subregion, operating system
Subregion and root file system subregion.
Alternatively, in the preparation method：In partition profile, with the behavior explanatory notes row of " # " beginning.
Alternatively, in the preparation method：The partition size of BOOT boot partitions is arranged to 1MB, environmental variance subregion
Partition size is arranged to 128KB, and the partition size of operating system partition is arranged to 4MB, the partition size of root file system subregion
It is arranged to 3MB.
Alternatively, in the preparation method：Software program data is by BOOT boot partitions data and operating system partition number
According to composition, initialization data is made up of environmental variance partition data and root file system partition data.
Alternatively, in the preparation method：Partition profile is stored in advance in LINUX equipment.
Alternatively, in the preparation method：Automatically generating for NOR FLASH recordable papers is completed by LINUX equipment.This hair
It is bright by adopting the above-described technical solution, so as to having advantages below：
1) operating procedure is few, avoid data recovery not exclusively (such as leakage recover etc.) the problem of；
2) avoid passing through tftp loading or backup recordable paper, will not because of the tftp softwares or network problem used and
Cause operation failure.
Brief description of the drawings
The present invention is described in further detail with reference to the accompanying drawings and detailed description：
Fig. 1 is the first embodiment schematic diagram of the NOR FLASH recordable paper preparation methods of the present invention.
Embodiment
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
There is the required accompanying drawing used in technology description to be briefly described, it should be apparent that, explanation and accompanying drawing are for the present invention below
It is exemplary, and is understood not to the limitation present invention.Numerous details are following description described to facilitate to this hair
Sensible solution.However, in some instances, well known or conventional details does not specify simultaneously, to meet the succinct requirement of specification.
In the prior art, there is also some NOR FLASH recordable paper preparation methods, but there is certain disadvantage in them
End, is mainly shown as that operating procedure is more, it is easy to error is introduced in certain operations link, is not yet present in the prior art soft
When part is issued, the technical scheme of NOR FLASH recordable papers is directly made.
In order to solve the above problems, the invention provides a kind of NOR FLASH recordable paper preparation methods, deposited using built-in
The LINUX equipment of memory device, under LINUX operating systems, directly the software of issue is entered according to default partition profile
