SDMMC调试

1. SDMMC配置，SDMMC hardware flow control使能 GPIO都拉高

 

 

 2.获取状态和SD卡信息

char GetStatus()
{
    int sdcard_status = 0;

    sdcard_status = HAL_SD_GetCardState(&hsd1);

    if(sdcard_status != HAL_SD_CARD_TRANSFER)
    {
        return 1;
    }
    return 0;
}

char GetInfo()
{
    int sdcard_status = 0;

    sdcard_status = HAL_SD_GetCardState(&hsd1);

    if(sdcard_status == HAL_SD_CARD_TRANSFER)
    {
        uint64_t CardCap;

        HAL_SD_CardCIDTypeDef SDCard_CID;
        HAL_SD_CardInfoTypeDef SDCardInfo;


        HAL_SD_GetCardInfo(&hsd1,&SDCardInfo);

        CardCap=(uint64_t)(SDCardInfo.LogBlockNbr)*(uint64_t)(SDCardInfo.LogBlockSize);

        switch(SDCardInfo.CardType)
        {

            case CARD_SDSC:

                {

                    if(SDCardInfo.CardVersion == CARD_V1_X)

                        printf("Card Type:SDSC V1\r\n");

                    else if(SDCardInfo.CardVersion == CARD_V2_X)

                        printf("Card Type:SDSC V2\r\n");

                }

                break;

                case CARD_SDHC_SDXC:printf("Card Type:SDHC\r\n");break;

                default:break;

        }

            printf("CardVersion: %d \r\n",(uint32_t)(SDCardInfo.CardVersion)); //SD鍗＄増鏈�??�??

            printf("Class: %d \r\n",(uint32_t)(SDCardInfo.Class)); //SD鍗＄被锟�????????

            printf("Card RCA(RelCardAdd):%d \r\n",SDCardInfo.RelCardAdd); //鍗＄浉�?�瑰湴锟�????????

            printf("Card BlockNbr: %d \r\n",SDCardInfo.BlockNbr); //鍧楁暟锟�????????

            printf("Card BlockSize: %d \r\n",SDCardInfo.BlockSize); //鍧楀ぇ锟�????????

            printf("LogBlockNbr: %d \r\n",(uint32_t)(SDCardInfo.LogBlockNbr)); //閫昏緫鍧楁暟锟�??????

            printf("LogBlockSize: %d \r\n",(uint32_t)(SDCardInfo.LogBlockSize)); //閫昏緫鍧�??ぇ锟�????????

            printf("Card Capacity: %d MB\r\n",(uint32_t)(CardCap>>20)); //SD鍗�?�锟�??????

            HAL_SD_GetCardCID(&hsd1,&SDCard_CID); //鑾峰彇CID
            printf("Card ManufacturerID: %d \r\n",SDCard_CID.ManufacturerID); //鍒讹�???锟藉晢ID
        return 0;
    }
    else
    {
        printf("SD card init fail! \r\n" );
        return 1;
    }
}
