Description
Technical field
The present invention relates to field of non-volatile memory, be specifically related to a kind of Nor flash update method and device.
Background technology
In embedded systems, generally adopt Nor flash as nonvolatile memory, for storing each several part program of embedded system.Typical Nor flash can comprise several subregions as shown in Figure 1, i.e. Bootloader subregion, Kernel subregion, Ramdisk subregion, user partition and extended partition.Wherein, Bootloader subregion is mainly used in storing boot, as redboot, uboot etc.; Kernel subregion is mainly used in storing operation system image, as linux; Ramdisk subregion is mainly used in storing the system and application program that infrequently upgrade; User partition is mainly used in the user application storing frequent updating; Extended partition is mainly used in the backup subregion as security of system pattern or significant data.
In order to run the application program of redaction, reaching the object of expanded function, generally connecting embedded system by certain mode, and by upgrade file bag, the Nor flash content in embedded system is upgraded.Wherein, upgrade file comprises the upgrade file of each subregion of needs upgrading.In existing Nor flash update method, the following scheme of general employing: 1) overall burning mode, upgrade file by each subregion is made into a size, shared address, upgrade file bag duplicate with Nor flash, then carries out man-to-manly copying programming to Nor flash by burning program; 2) part burning mode, namely uses subregion sign to be organized by upgrade file, by identifying subregion sign, by upgrade file programming in correct subregion.When Nor flash comprises multiple hardware platform, can according to 1) or 2) burning mode, upgrade separately the upgrade file of each hardware platform, or upgrade the upgrade file of all hardware platform.
But, at least there is following problem in such scheme: 1) overall burning mode, upgrade file bag must be the same with the size of Nor flash, if comprise the upgrade file of all hardware platform in upgrade file bag, then greatly can reduce Nor flash and upgrade efficiency; 2) part burning mode, the size that the capacity of upgrade file can not specify more than Nor flash subarea, otherwise will the content of a rear subregion be covered, and the subregion of each hardware platform is generally differentiated, virtually can reduce the dirigibility that Nor flash upgrades.
Summary of the invention
For above-mentioned defect, embodiments provide a kind of Nor flash update method and device, Nor flash can be improved and upgrade efficiency and dirigibility.
A kind of Nor flash update method, comprising:
Read the upgrade file in the upgrade file bag made in advance;
Judge whether include hardware platform mark in described upgrade file, if comprise hardware platform mark, then judge whether described hardware platform mark is the hardware platform mark mated further, if the hardware platform mark of coupling, then judge the Nor flash subarea mark whether including described hardware platform in described upgrade file further, if include the Nor flash subarea mark of described hardware platform, the Nor flash subarea start address of the described hardware platform then comprised by described upgrade file and Nor flash subarea size are as the burning program parameter of described Nor flash, and the respective regions wiped in described Nor flash corresponding to described Nor flash subarea mark,
The data that shared by the data reading out byte number and the described hardware platform that described upgrade file comprises from the upgrade data that described upgrade file comprises, byte number is equal are as more new data;
By burning program by the programming of described more new data in the respective regions in described Nor flash corresponding to the described Nor flash subarea mark wiped.
A kind of Nor flash updating device, comprising:
Read module, for reading the upgrade file in the upgrade file bag that makes in advance;
First judge module, for judging whether include hardware platform mark in the upgrade file that described read module reads;
Second judge module, for when the judged result of described first judge module is for being, judges whether described hardware platform mark is the hardware platform mark mated;
3rd judge module, for when the judged result of described second judge module is for being, judges the Nor flash subarea mark whether including described hardware platform in described upgrade file;
Erasing module, for when the judged result of described 3rd judge module is for being, the Nor flash subarea start address of the described hardware platform comprised by described upgrade file and Nor flash subarea size as the burning program parameter of described Nor flash, and wipe the respective regions in described Nor flash corresponding to described Nor flash subarea mark;
Described read module, also for read out byte number and the described hardware platform that described upgrade file comprises in the upgrade data that comprises from described upgrade file data shared by the equal data of byte number as more new data;
Burning program module, for by burning program by the programming of described more new data in the respective regions in described Nor flash corresponding to the described Nor flash subarea mark wiped.
In the embodiment of the present invention, if include hardware platform mark in the upgrade file read, and this hardware platform mark is the hardware platform mark of coupling, then judge whether include Nor flash subarea mark in the upgrade file read further, the Nor flash subarea start address of this hardware platform if it is comprised by upgrade file and Nor flash subarea size are as the burning program parameter of Nor flash, and the respective regions wiped in Nor flash corresponding to Norflash subregion sign, and the data that shared by the data reading out byte number and this hardware platform that upgrade file comprises from the upgrade data that upgrade file comprises, byte number is equal are as more new data, and programming is in the respective regions in Nor flash corresponding to the Nor flash subarea mark wiped, thus realize upgrading Nor flash.Pass through such scheme, when Nor flash is upgraded, no longer only be confined to the Nor flash (i.e. part burning mode) upgrading whole Nor flash (i.e. overall burning mode) or fixed partition, but the hardware platform mark by being comprised by upgrade file, Nor flash subarea mark, the Nor flash update area that Nor flash subarea start address and Nor flash subarea size are determined, and the more new data that shared by the data of the upgrade data to be comprised by upgrade file and hardware platform, byte number is determined realizes the renewal to Nor flash, thus Nor flash renewal efficiency and dirigibility can be improved.
