Burst同步模式配置正确了么？
BURSTEN@FSMC_BCRx = 1
谢谢香版，附上我的配置，麻烦帮忙看看
void FSMCConfig(void)
{
/*----------------------- SRAM Bank 1 ----------------------------------------*/
memset((unsigned char *)&p, 0, sizeof(FSMC_NORSRAMTimingInitTypeDef));
memset((unsigned char *)&FSMC_NORSRAMInitStructure, 0, sizeof(FSMC_NORSRAMInitTypeDef));
p.FSMC_BusTurnAroundDuration = 1; //总线恢复时间
p.FSMC_CLKDivision = 1; //时钟分频因子
p.FSMC_DataLatency = 0; //数据产生时间
FSMC_NORSRAMInitStructure.FSMC_Bank = FSMC_Bank1_NORSRAM1; //BANK1 NORSRAM1
FSMC_NORSRAMInitStructure.FSMC_DataAddressMux = FSMC_DataAddressMux_Enable; //地址数据总线复用
FSMC_NORSRAMInitStructure.FSMC_MemoryType = FSMC_MemoryType_PSRAM;//FSMC_MemoryType_NOR;
FSMC_NORSRAMInitStructure.FSMC_MemoryDataWidth = FSMC_MemoryDataWidth_16b;
FSMC_NORSRAMInitStructure.FSMC_BurstAccessMode = FSMC_BurstAccessMode_Enable;
FSMC_NORSRAMInitStructure.FSMC_WaitSignalPolarity = FSMC_WaitSignalPolarity_Low;
FSMC_NORSRAMInitStructure.FSMC_WrapMode = FSMC_WrapMode_Disable;
FSMC_NORSRAMInitStructure.FSMC_WaitSignalActive = FSMC_WaitSignalActive_BeforeWaitState;
FSMC_NORSRAMInitStructure.FSMC_WriteOperation = FSMC_WriteOperation_Enable;
FSMC_NORSRAMInitStructure.FSMC_WaitSignal = FSMC_WaitSignal_Disable;
FSMC_NORSRAMInitStructure.FSMC_ExtendedMode = FSMC_ExtendedMode_Disable;
FSMC_NORSRAMInitStructure.FSMC_WriteBurst = FSMC_WriteBurst_Enable;
FSMC_NORSRAMInitStructure.FSMC_ReadWriteTimingStruct = &p;
FSMC_NORSRAMInitStructure.FSMC_WriteTimingStruct = &p;
FSMC_NORSRAMInit(&FSMC_NORSRAMInitStructure);
/* BANK 1 (of NOR/SRAM Bank 1~4) is enabled */
FSMC_NORSRAMCmd(FSMC_Bank1_NORSRAM1, ENABLE);
