SDcard and LCD ?

Guys,

I have a question about SDcard and LCD initialization , Everytime I intialize LCD after SDcard, SDcard stopped working, is it because of port clock ? Thanks SDcard initialization :

void
SD_LowLevel_Init(
void
)

{

GPIO_InitTypeDef GPIO_InitStructure;


/*!< GPIOC and GPIOD Periph clock enable */

RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOC | RCC_APB2Periph_GPIOD | SD_DETECT_GPIO_CLK, ENABLE);


/*!< Configure PC.08, PC.09, PC.10, PC.11, PC.12 pin: D0, D1, D2, D3, CLK pin */

GPIO_InitStructure.GPIO_Pin = GPIO_Pin_8 | GPIO_Pin_9 | GPIO_Pin_10 | GPIO_Pin_11 | GPIO_Pin_12;

GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;

//GPIO_InitStructure.GPIO_Speed = GPIO_Speed_10MHz;

GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;

GPIO_Init(GPIOC, &GPIO_InitStructure);


/*!< Configure PD.02 CMD line */

GPIO_InitStructure.GPIO_Pin = GPIO_Pin_2;

GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;

GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;

GPIO_Init(GPIOD, &GPIO_InitStructure);


/*!< Configure SD_CD pin: SD Card detect pin */

GPIO_InitStructure.GPIO_Pin = SD_DETECT_PIN;

GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IPU;

GPIO_Init(SD_DETECT_GPIO_PORT, &GPIO_InitStructure);


/*!< Enable the SDIO AHB Clock */

RCC_AHBPeriphClockCmd(RCC_AHBPeriph_SDIO, ENABLE);


/*!< Enable the DMA2 Clock */

RCC_AHBPeriphClockCmd(RCC_AHBPeriph_DMA2, ENABLE);

}

LCD initialization :

static
void
LCD_CtrlLinesConfig(
void
)

{

GPIO_InitTypeDef GPIO_InitStructure;


/* Enable FSMC, GPIOD, GPIOE and AFIO clocks */

RCC_AHBPeriphClockCmd(RCC_AHBPeriph_FSMC, ENABLE);


RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOD | RCC_APB2Periph_GPIOE | RCC_APB2Periph_AFIO, ENABLE);


/* PE.07(D4), PE.08(D5), PE.09(D6), PE.10(D7), PE.11(D8), PE.12(D9),

PE.13(D10), PE.14(D11), PE.15(D12) */

GPIO_InitStructure.GPIO_Pin = GPIO_Pin_7 | GPIO_Pin_8 | GPIO_Pin_9 | GPIO_Pin_10 |

GPIO_Pin_11 | GPIO_Pin_12 | GPIO_Pin_13 | GPIO_Pin_14 | 

GPIO_Pin_15;

GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;

GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;

GPIO_Init(GPIOE, &GPIO_InitStructure);


/* PD.00(D2), PD.01(D3), PD.04(RD), PD.5(WR), PD.7(CS), PD.8(D13), PD.9(D14),

PD.10(D15), PD.11(RS) PD.14(D0) PD.15(D1) */

GPIO_InitStructure.GPIO_Pin = GPIO_Pin_0 | GPIO_Pin_1 | GPIO_Pin_4 | GPIO_Pin_5 | GPIO_Pin_7 | 

GPIO_Pin_8 | GPIO_Pin_9 | GPIO_Pin_10 | GPIO_Pin_11 | 

GPIO_Pin_14 | GPIO_Pin_15;

GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;

//GPIO_InitStructure.GPIO_Speed = GPIO_Speed_10MHz;

GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;

GPIO_Init(GPIOD, &GPIO_InitStructure);

}

Is it possible for DMA conflict between SDIO and FSMC, since SDIO is using DMA channel4 ?...

 

I don't know, what do you think the conflict would be? Is there some documentation that suggests there is? Are you DMA'ing from the SDIO to the FSMC external memory. Debugging should have to be about random guessing.

Your FSMC configuration is broken, if your read/write parameters are actually different you need to create TWO descriptors, calling FSMC_Init() twice doesn't work that way.

any better suggestions for it ? thanks

For now, I fixed it by using only one configuration for read and write for FSMC, now I can initialize LCD before SDcard and it's working allright.....thanks
