Abstract
The invention relates to the field of embedded software, in particular to a method for processing software automatically compatible with various types of FLASH. The invention discloses a method for processing the software automatically compatible with various types of FLASH. The key points of the technical proposal are as follows: the method for processing the software automatically compatible with various types of FLASH comprises the following steps: a. when the system is initialized, the characteristic IDs of the FLASH are read so as to identify the category and the type of the FLASH; b. the corresponding initialization program is called to initialize the corresponding FLASH according to the identified category and type of the FLASH; and c. the corresponding read-write drive program is called to execute the read-write operation according to the identified category and type of the FLASH. The invention has the following beneficial effects: the adoption of one edition of software can realize the compatibility to various types of FLASH; the maintenance is simple; and the error occurrence is not easy; and the invention is applicable to the development of embedded software.
Description
Technical field
The present invention relates to field of embedded software, relate in particular to a kind of software processing method of automatic compatible with multiple model FLASH.
Background technology
Embedded product in the market is ubiquitous, and the memory device of embedded product all is to adopt FLASH (flash memory) basically, is used to store corresponding program and data.And the FLASH of appearance in the market is of a great variety, and the driver that different production firms provides is also different.In the prior art, when embedded product uses the FLASH of fixed type, may be owing to its corresponding driver is changed in the update of FLASH, the software that regenerates a version is safeguarded, will cause same embedded product to need a plurality of different software versions to safeguard that maintenance is also made mistakes greatly easily like this.
Summary of the invention
Technical matters to be solved by this invention is: at deficiency of the prior art, propose the software processing method of the multiple model FLASH of a kind of automatic compatible processing.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of software processing method of automatic compatible with multiple model FLASH may further comprise the steps:
A. during system initialization, read the characteristic ID of FLASH, type and the model of identification FLASH;
B. according to type and the model of the FLASH that discerns, call the FLASH of corresponding initialize routine initialization correspondence;
C. according to type and the model of the FLASH that discerns, call corresponding read-write driver and carry out read-write motion.
The invention has the beneficial effects as follows: only adopt a software version to get final product the FLASH of compatible multiple model, safeguard simply, be difficult for makeing mistakes.
Description of drawings
Fig. 1 is a method flow diagram of the present invention;
Fig. 2 is the initialization flow process to multiple model FLASH compatibility;
Fig. 3 is the read-write flow process to multiple model FLASH compatibility.
Embodiment
The invention will be further described below in conjunction with drawings and Examples.
As shown in Figure 1, the software processing method among the present invention adopts following steps to implement: during a. system initialization, read the characteristic ID of FLASH, type and the model of identification FLASH; B. according to type and the model of the FLASH that discerns, call the FLASH of corresponding initialize routine initialization correspondence; C. according to type and the model of the FLASH that discerns, call corresponding read-write driver and carry out read-write motion.
Embodiment:
At first when system initialization, read the characteristic ID of FLASH, type and the model of identification FLASH as shown in Figure 2, judge whether to be FLASH1 according to its type and model, if, then call the FLASH1 initialize routine it is carried out initialization, if not, then judge whether to be FLASH2, if then call the initialize routine of FLASH2 it is carried out initialization, if not then continuing to judge whether to be other models FLASH.When application program need be read and write FLASH, as shown in Figure 3, FLASH type and model according to identification judge whether to be FLASH1, if, the read-write driver that then calls FLASH1 carries out read-write operation, if not then judging whether to be FLASH2, carry out read-write operation if then call the read-write driving of FLASH2, if not then continuing to judge whether to be other types FLASH.
Claims (1)
- The software processing method of [claim 1] a kind of automatic compatible with multiple model FLASH is characterized in that: may further comprise the steps:A. during system initialization, read the characteristic ID of FLASH, type and the model of identification FLASH;B. according to type and the model of the FLASH that discerns, call the FLASH of corresponding initialize routine initialization correspondence;C. according to type and the model of the FLASH that discerns, call corresponding read-write driver and carry out read-write motion.
