Embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched
The specific embodiment stated is used only for explaining the present invention, rather than limitation of the invention.It also should be noted that in order to just
It illustrate only part related to the present invention rather than entire infrastructure in description, attached drawing.
Fig. 1 is the flow chart of the profile acquisition method of SPI-NAND provided in an embodiment of the present invention, and the present embodiment can
Suitable for the situation of the initial burning of firmware to SPI-NAND, this method can carry out setting for burning by the firmware of SPI-NAND
It is standby, such as computer performs, and specifically comprises the following steps：
Step 101, receive firmware burning instruction, and firmware burning instruction, which is used to trigger, carries out just the firmware of SPI-NAND
Beginning burning；
Whatsoever the SPI-NAND of brand, model is required for carrying out initial burning before dispatching from the factory, in order to set SPI-
Relevant parameters and storage rule of the NAND during follow-up use, therefore to carry out user before initial burning on computers
Operation produces firmware burning instruction, which starts to carry out initial burning to the firmware of SPI-NAND.This implementation
It can be by installing application program on computers come real that example Computer, which carries out the firmware of SPI-NAND initial burning,
It is existing
Step 102, the configuration file previously generated according to firmware burning instruction calls, the configuration file are used to provide first
The value for the configuration parameter being related to during beginning burning；
Computer calls configuration file, which is to be pre-designed simultaneously by running simulator and autoexec
Generation, Fig. 2 is the structure diagram of configuration file provided in an embodiment of the present invention, as shown in Fig. 2, at least being wrapped in configuration file
Include following information：Bad block block scan, block percentage (including user blocks and the respective percentage of idle block), two-region block letter
Breath, randomizer setting, NAND type detection, metadata and the ECC of user data and extension are reserved.These information are
During initial burning, the configuration parameter that operation needs to index, verify and use is powered on.
Step 103, by configuration file be stored in SPI-NAND in reserved area, so as to from reserved area extract configuration parameter
Value.
Computer runs programs carry configuration file, the reserved area being deposited into SPI-NAND, the reserved area are
The most stable of region of storage performance in SPI-NAND, is the exclusive region of configuration file, and the use usually not to SPI-NAND is used
Family opens.Fig. 3 is the block diagram of reserved area provided in an embodiment of the present invention, as shown in figure 3, reserved area includes first
