Embodiment
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, clear, complete description is carried out to the specific embodiment of the present invention, obviously, described embodiment is a part of embodiment of the present invention, instead of whole embodiment, neither limitation of the present invention.Based on embodiments of the invention, those of ordinary skill in the art, not paying the every other embodiment obtained under creative work prerequisite, belong to protection scope of the present invention.
The process flow diagram of the generation method of the NAND Flash programmable device burning image file that Fig. 1 provides for the embodiment of the present invention one.As shown in Figure 1, the method comprising the steps of S1, to step S3, is described in detail to step S3 to step S1 below respectively.
The present embodiment is used for generating NAND Flash programmable device burning image file to three software modules (the first software module, the second software module and the 3rd software module), wherein the storage organization of NAND Flash programmable device is: block capacity is 128KB, page capacity is 2KB, sector capacity is 512B, and its CPU mode of operation is small end alignment pattern.
Step S1: additional Spare area data obtain the Bin_spare_area file of each software module on the original binary data basis of each software module respectively.
Be described for the first software module particularly:
Be one group according to every 512 bytes to divide into groups to the original binary data of the first software module;
Generate the ECC check code often organizing data respectively, wherein ECC check code is the data of 16 bytes;
The ECC check code combination often organizing data is obtained Spare area data;
Original binary data and Spare area data assemblies are obtained the Bin_spare_area file of the first software module.
Adopt identical method can obtain the Bin_spare_area file of the second software module and the Bin_spare_area file of the 3rd software module.
Step S2: carry out internal memory registration process to the original binary data in the Bin_spare_area file of each software module respectively, obtains the Bin_swapping file of each software module.
Large end pattern and little endian mode is had in data storage method, large end pattern, refer to that the high byte of data is kept in the low address of internal memory, and the low byte of data is kept in the high address of internal memory, such memory module is a bit similar to is used as data as character string sequential processes: address is by little to large increase, and data are put from high-order toward low level; Little endian mode, refer to that the high byte of data is kept in the high address of internal memory, and the low byte of data is kept in the low address of internal memory, the height of address and data bit power combine by this memory module effectively, high address part weights are high, low address part weights are low, consistent with our logical method.Because in the present embodiment, the structure of NAND programming cd-rom recorder is little endian mode, therefore need to carry out small end registration process to original binary data.The Bin_spare_area file of the first software module is that example is described particularly: first the original binary data in the Bin_spare_area file of the first software module is one group according to every 4 bytes and divides into groups; Carry out small end registration process by often organizing data, the high byte by data is kept in the high address of internal memory, the low byte of data is kept at the low address of internal memory, obtains the align data that original binary data is corresponding; The align data of original binary data in Bin_spare_area file by its correspondence is replaced, obtains the Bin_swapping file of the first software module.Adopt identical method can obtain the Bin_swapping file of the second software module and the Bin_swapping file of the 3rd software module respectively.Because the embodiment of the present invention is the Bin_swapping file generating each software module respectively, therefore regenerating and changing of each software module burning image file conveniently can be realized.
Step S3: the Bin_swapping Piece file mergence of each software module is obtained burning image file.
Particularly, Bin_swapping file corresponding to each software module is obtained respectively through step S2, adopt the Piece file mergence instrument that NAND programmable device provides, according to the allocation table of system external space, the Bin_swapping file of the Bin_swapping file of the Bin_swapping file of the first software module, the second software module, the 3rd software module is carried out merging and can obtain NAND burning image file
