[SCM] cheap_flash_fs_32bits DL : 0: Cheap_Flash_FS 嵌入式NandFlash文件系统源码下载 Cheap_Flash_FS 代码已经由我们开发完成，并经过了严格的测试。坏块管理功能包括基于坏块表的管理程序，可以提供单/多扇区的操作。多扇区为nandflash专门设计，可以降低NANDFLASH物理擦除数，具有直接预分配功能(降低内存占用量)。其上面可以运行（Cheap_Flash_FS（支持多扇区操作））文件系统。文件系统可支持实时坏块替换，包括擦除块，块移动，写入页产生坏块。文件系统基于NAND_FLASH坏块管理层驱动运行。 NAND_FLASH坏块管理支持ECC纠错，对每个扇区执行二次ECC纠错，保证数据正确的读出。 NAND_FLASH坏块管理层如果发现Unrecoverable_error扇区，可把扇区读出置为0，等于目录已结束，避免了文件系统运行出错。本代码是32BIT的坏块表文件系统，可支持大于4G的nandflash，包括小页,中页，大页，用于用户代码测试！可以用于U盘和SD卡的设计上。以及其它大容量存储项目上。 qq:292942278 e-mail:tony_yang123@sina.com-Cheap_Flash_FS (STM32F103ZET6)- embedded NandFlash file system C free download code The Cheap_Flash_FS code has been developed by us to complete, and through rigorous testing. Bad block management functions include bad block table management based procedures, can provide single/multi sector operation. The multi sector designed specifically for nandflash, can reduce the NANDFLASH physical wiping the divisor. The above can be run (Cheap_Flash_FS (multi sector operations)) file system. The file system can support real-time bad block replacement, including the erase block, block movement, write page generated bad block. The file system based on NAND_FLASH bad block management drive operation. NAND_FLASH bad block management support ECC correction, for each sector performed two times ECC correction, ensure that read data correctly. NAND_FLASH bad block management if it is found that the Unrecoverable_error sector, the sector can be read out is set to 0, equal to the direct
