I dig into the problem step by step:
error happens in:
DSTATUS SD_initialize(BYTE lun)
{
Stat = STA_NOINIT;
/* Configure the uSD device */
if(BSP_SD_Init() == MSD_OK)
{
Stat &= ~STA_NOINIT;
}
return Stat;
}�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?
Error happens in BSP_SD_Init(). With further dig, it bump into :
HAL_SD_ErrorTypedef HAL_SD_Init(SD_HandleTypeDef *hsd, HAL_SD_CardInfoTypedef *SDCardInfo)
{
__IO HAL_SD_ErrorTypedef errorstate = SD_OK;
SD_InitTypeDef tmpinit;
/* Allocate lock resource and initialize it */
hsd->Lock = HAL_UNLOCKED;
/* Initialize the low level hardware (MSP) */
HAL_SD_MspInit(hsd);
/* Default SDIO peripheral configuration for SD card initialization */
tmpinit.ClockEdge = SDIO_CLOCK_EDGE_RISING;
tmpinit.ClockBypass = SDIO_CLOCK_BYPASS_DISABLE;
tmpinit.ClockPowerSave = SDIO_CLOCK_POWER_SAVE_DISABLE;
tmpinit.BusWide = SDIO_BUS_WIDE_1B;
tmpinit.HardwareFlowControl = SDIO_HARDWARE_FLOW_CONTROL_DISABLE;
tmpinit.ClockDiv = SDIO_INIT_CLK_DIV;
/* Initialize SDIO peripheral interface with default configuration */
SDIO_Init(hsd->Instance, tmpinit);
/* Identify card operating voltage */
errorstate = SD_PowerON(hsd);
if(errorstate != SD_OK)
{
return errorstate;
}
/* Initialize the present SDIO card(s) and put them in idle state */
errorstate = SD_Initialize_Cards(hsd);
if (errorstate != SD_OK)
{
return errorstate;
}
/* Read CSD/CID MSD registers */
errorstate = HAL_SD_Get_CardInfo(hsd, SDCardInfo);
if (errorstate == SD_OK)
{
/* Select the Card */
errorstate = SD_Select_Deselect(hsd, (uint32_t)(((uint32_t)SDCardInfo->RCA) << 16));
}
/* Configure SDIO peripheral interface */
SDIO_Init(hsd->Instance, hsd->Init);
return errorstate;
}�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?
The problem happens in /* Identify card operating voltage */
errorstate =
SD_PowerON(hsd); ; returns
SD_COM_CRC_FAILED.
Any idea?
