//升级说明
|
|
//V1.1 20160124
|
|
//修改FTL_CopyAndWriteToBlock和FTL_WriteSectors函数,提高非0XFF时的写入速度.
|
|
//V1.2 20160520
|
|
//1,修改FTL_ReadSectors,增加ECC出错判断,检测坏块处理,并增加多块连读,提高速度
|
|
//2,新增FTL_BlockCompare和FTL_SearchBadBlock函数,用于搜寻坏块
|
|
//3,修改FTL_Format坏块检测方式,增加FTL_USE_BAD_BLOCK_SEARCH宏
|
|
//V1.3 20160530
|
|
//修改当1bit ECC错误出现时，读取2次，来确认1bit 错误，以防错误的修改数据
|
