STM32 under the fatfs of the transplant, to achieve the write-off balance, bad block management, hardware ECC,ECC error correction

Recently, as a result of the project needs, do a data acquisition of single-chip computer platform. Need to transplant FatFs. Now put the final results on the surface.

On the STM32 single-chip microcomputer, successfully transplanted FatFs 0.12b, using the Nand Flash chip for k9f2g08.

Features: System with FatFs to achieve the erase and write equalization, bad block management, hardware ECC, software ECC error correction

File composition:

FatFs Directory

+----FFCONF.H files configured for FatFs

+----Ff.h

+----FF.C is a FatFs implementation file, and the erase-write equalization is implemented in the F_getfree function.

+----CCSBCS.C file name support in English

+----CC936.C file name support Chinese

+----DISKIO.C is an interface function between FatFs and a custom drive layer

+----NANDDISK.C for its own implementation of the Nandflash matching function, bad block management is implemented here. BSP Directory

+----Fsmc_nand.h definition of various parameters of K9F2G08

+----FSMC_NAND.C Implements hardware-level read-write drivers, STM32 's hardware ECC is used here. ECC Automatic error correction is also implemented.

Note: In order to obtain a 64*2k erase buffer, the system also uses a SRAM chip to support malloc memory allocation functions. This file is provided by your own system.
