我是在安富莱开发板上用的FSMC for NAND Flash程序,后来移植到103VE芯片上了,可是光NAND_ReadID(&NAND_ID);都没读回来:
FSMC配置:
-
- /*-- FSMC Configuration ------------------------------------------------------*/
- p.FSMC_SetupTime = 0x1;
- p.FSMC_WaitSetupTime = 0x3;
- p.FSMC_HoldSetupTime = 0x2;
- p.FSMC_HiZSetupTime = 0x1;
- FSMC_NANDInitStructure.FSMC_Bank = FSMC_Bank2_NAND;
- FSMC_NANDInitStructure.FSMC_Waitfeature = FSMC_Waitfeature_Enable;
- FSMC_NANDInitStructure.FSMC_MemoryDataWidth = FSMC_MemoryDataWidth_8b;
- FSMC_NANDInitStructure.FSMC_ECC = FSMC_ECC_Enable;
- FSMC_NANDInitStructure.FSMC_ECCPageSize = FSMC_ECCPageSize_2048Bytes;
-
- FSMC_NANDInitStructure.FSMC_AddressLowMapping = FSMC_AddressLowMapping_Direct;
- FSMC_NANDInitStructure.FSMC_TCLRSetupTime = 0x00;
- FSMC_NANDInitStructure.FSMC_TARSetupTime = 0x00;
- FSMC_NANDInitStructure.FSMC_CommonSpaceTimingStruct = &p;
- FSMC_NANDInitStructure.FSMC_AttributeSpaceTimingStruct = &p;
- FSMC_NANDInit(&FSMC_NANDInitStructure);
- /* FSMC NAND Bank Cmd Test */
- FSMC_NANDCmd(FSMC_Bank2_NAND, ENABLE);
