Connecting FPGA to STM32F407 over FMC in Muxed mode

[kazem_baadpie]

HI,

I want to connect a FPGA to stm32F407 in 8 bits multiplexed FSMC. I have tried many configurations but in none of them ALE(PD12) or NADV(PB7) generate latch pulse. Here is my code :

static void CPLD_GPIO_Config(void)
{
GPIO_InitTypeDef GPIO_InitStructure;

GPIO_InitStructure.GPIO_Pin = dfPortRstCPLD;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_OUT;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_2MHz;
GPIO_InitStructure.GPIO_OType = GPIO_OType_PP;
GPIO_InitStructure.GPIO_PuPd = GPIO_PuPd_NOPULL;
GPIO_Init(GPIOA, &GPIO_InitStructure);
GPIO_SetBits(GPIOA, dfPortRstCPLD);
Delay(2);
GPIO_ResetBits(GPIOA, dfPortRstCPLD);
Delay(2);
GPIO_SetBits(GPIOA, dfPortRstCPLD);
Delay(2);

// GPIOD : FSMC D0~D3, NWE(WR), NE1(CS) , ALE?
GPIO_PinAFConfig(GPIOD, GPIO_PinSource0, GPIO_AF_FSMC); // D2
GPIO_PinAFConfig(GPIOD, GPIO_PinSource1, GPIO_AF_FSMC); // D3
GPIO_PinAFConfig(GPIOD, GPIO_PinSource5, GPIO_AF_FSMC); // NWE
GPIO_PinAFConfig(GPIOD, GPIO_PinSource7, GPIO_AF_FSMC); // NE1
GPIO_PinAFConfig(GPIOD, GPIO_PinSource12, GPIO_AF_FSMC); // ALE
GPIO_PinAFConfig(GPIOD, GPIO_PinSource14, GPIO_AF_FSMC); // D0
GPIO_PinAFConfig(GPIOD, GPIO_PinSource15, GPIO_AF_FSMC); // D1

GPIO_InitStructure.GPIO_Pin = GPIO_Pin_0 | GPIO_Pin_1 | GPIO_Pin_5 | GPIO_Pin_7 | GPIO_Pin_12 | GPIO_Pin_14 | GPIO_Pin_15;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_100MHz;
GPIO_Init(GPIOD, &GPIO_InitStructure);

// GPIOB : FSMC NADV(ALE)
GPIO_PinAFConfig(GPIOB, GPIO_PinSource7, GPIO_AF_FSMC);
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_7;
GPIO_Init(GPIOB, &GPIO_InitStructure);

// GPIOE : FSMC D4~D7
GPIO_PinAFConfig(GPIOE, GPIO_PinSource7, GPIO_AF_FSMC);
GPIO_PinAFConfig(GPIOE, GPIO_PinSource8, GPIO_AF_FSMC);
GPIO_PinAFConfig(GPIOE, GPIO_PinSource9, GPIO_AF_FSMC);
GPIO_PinAFConfig(GPIOE, GPIO_PinSource10, GPIO_AF_FSMC);
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_7 | GPIO_Pin_8 |GPIO_Pin_9 |GPIO_Pin_10;
GPIO_Init(GPIOE, &GPIO_InitStructure);
}
//--------------------------------------------

static void FSMC_Init(void)
{
FSMC_NORSRAMTimingInitTypeDef Timing;
FSMC_NORSRAMInitTypeDef FSMC_Init;

RCC_AHB3PeriphClockCmd(RCC_AHB3Periph_FSMC, ENABLE);

Timing.FSMC_AddressSetupTime = 2;
Timing.FSMC_AddressHoldTime = 2;
Timing.FSMC_DataSetupTime = 2;
Timing.FSMC_BusTurnAroundDuration = 0;
Timing.FSMC_CLKDivision = 0;
Timing.FSMC_DataLatency = 0;
Timing.FSMC_AccessMode = FSMC_AccessMode_A;

FSMC_Init.FSMC_Bank = FSMC_Bank1_NORSRAM1;
FSMC_Init.FSMC_DataAddressMux = FSMC_DataAddressMux_Enable;
FSMC_Init.FSMC_MemoryType = FSMC_MemoryType_SRAM;
FSMC_Init.FSMC_MemoryDataWidth = FSMC_MemoryDataWidth_8b;
FSMC_Init.FSMC_BurstAccessMode = FSMC_BurstAccessMode_Disable;
FSMC_Init.FSMC_AsynchronousWait = FSMC_AsynchronousWait_Disable;
FSMC_Init.FSMC_WaitSignalPolarity = FSMC_WaitSignalPolarity_Low;
FSMC_Init.FSMC_WrapMode = FSMC_WrapMode_Disable;
FSMC_Init.FSMC_WaitSignalActive = FSMC_WaitSignalActive_BeforeWaitState;
FSMC_Init.FSMC_WriteOperation = FSMC_WriteOperation_Enable;
FSMC_Init.FSMC_WaitSignal = FSMC_WaitSignal_Disable;
FSMC_Init.FSMC_ExtendedMode = FSMC_ExtendedMode_Disable;
FSMC_Init.FSMC_WriteBurst = FSMC_WriteBurst_Disable;
FSMC_Init.FSMC_ReadWriteTimingStruct = &Timing;
FSMC_Init.FSMC_WriteTimingStruct = &Timing;

FSMC_NORSRAMInit(&FSMC_Init);
FSMC_NORSRAMCmd(FSMC_Bank1_NORSRAM1, ENABLE);
}
//--------------------------------------------

Is it possible to connect FPGA to STNM32F407 in 8 bits multiplexed FSMC ? Is my code correct ?
