Hello,
I have a stm42f411 with SDIO 4B configured and working properly.
the SDIO conf is the following:
hsd.Instance = SDIO;
hsd.Init.ClockEdge = SDIO_CLOCK_EDGE_RISING;
hsd.Init.ClockBypass = SDIO_CLOCK_BYPASS_DISABLE;
hsd.Init.ClockPowerSave = SDIO_CLOCK_POWER_SAVE_DISABLE;
hsd.Init.BusWide = SDIO_BUS_WIDE_4B;
hsd.Init.HardwareFlowControl = SDIO_HARDWARE_FLOW_CONTROL_DISABLE;
hsd.Init.ClockDiv = 8;
/* USER CODE BEGIN SDIO_Init 2 */
hsd.Init.BusWide = SDIO_BUS_WIDE_1B;
if (HAL_SD_Init(&hsd) != HAL_OK){
log_error("MX_SDIO_SD_Init: error HAL_SD_Init");
}
if (HAL_SD_ConfigWideBusOperation(&hsd, SDIO_BUS_WIDE_4B) != HAL_OK){
log_error("MX_SDIO_SD_Init: HAL_SD_ConfigWideBusOperation error");
}
Over 10 SDCard, same brand, all working on linux, windows, only 4 are passing without error the Hal_SD_init and ConfigWideBusOperation
in Hal_SD_Init
static uint32_t SD_PowerON(SD_HandleTypeDef *hsd)
{
__IO uint32_t count = 0U;
uint32_t response = 0U, validvoltage = 0U;
uint32_t errorstate;
/* CMD0: GO_IDLE_STATE */
errorstate = SDMMC_CmdGoIdleState(hsd->Instance);
if(errorstate != HAL_SD_ERROR_NONE)
{
return errorstate;
}
/* CMD8: SEND_IF_COND: Command available only on V2.0 cards */
errorstate = SDMMC_CmdOperCond(hsd->Instance);
if(errorstate != HAL_SD_ERROR_NONE)
{
hsd->SdCard.CardVersion = CARD_V1_X;
/* CMD0: GO_IDLE_STATE */
errorstate = SDMMC_CmdGoIdleState(hsd->Instance);
if(errorstate != HAL_SD_ERROR_NONE)
{
return errorstate;
}
I received an errorState==4
It is coming from :
uint32_t SDMMC_CmdOperCond(SDIO_TypeDef *SDIOx)
{
SDIO_CmdInitTypeDef sdmmc_cmdinit;
uint32_t errorstate;
/* Send CMD8 to verify SD card interface operating condition */
/* Argument: - [31:12]: Reserved (shall be set to '0')
- [11:8]: Supply Voltage (VHS) 0x1 (Range: 2.7-3.6 V)
- [7:0]: Check Pattern (recommended 0xAA) */
/* CMD Response: R7 */
sdmmc_cmdinit.Argument = SDMMC_CHECK_PATTERN;
sdmmc_cmdinit.CmdIndex = SDMMC_CMD_HS_SEND_EXT_CSD;
sdmmc_cmdinit.Response = SDIO_RESPONSE_SHORT;
sdmmc_cmdinit.WaitForInterrupt = SDIO_WAIT_NO;
sdmmc_cmdinit.CPSM = SDIO_CPSM_ENABLE;
(void)SDIO_SendCommand(SDIOx, &sdmmc_cmdinit);
/* Check for error conditions */
errorstate = SDMMC_GetCmdResp7(SDIOx);
return errorstate;
}
and inside
uint32_t SDMMC_GetCmdResp7(SDIO_TypeDef *SDIOx)
{
uint32_t sta_reg;
/* 8 is the number of required instructions cycles for the below loop statement.
The SDIO_CMDTIMEOUT is expressed in ms */
uint32_t count = SDIO_CMDTIMEOUT * (SystemCoreClock / 8U /1000U);
do
{
if (count-- == 0U)
{
return SDMMC_ERROR_TIMEOUT;
}
sta_reg = SDIOx->STA;
}while(((sta_reg & (SDIO_FLAG_CCRCFAIL | SDIO_FLAG_CMDREND | SDIO_FLAG_CTIMEOUT)) == 0U) ||
((sta_reg & SDIO_FLAG_CMDACT) != 0U ));
if(__SDIO_GET_FLAG(SDIOx, SDIO_FLAG_CTIMEOUT))
{
/* Card is SD V2.0 compliant */
__SDIO_CLEAR_FLAG(SDIOx, SDIO_FLAG_CTIMEOUT);
return SDMMC_ERROR_CMD_RSP_TIMEOUT;
}
else if(__SDIO_GET_FLAG(SDIOx, SDIO_FLAG_CCRCFAIL))
{
/* Card is SD V2.0 compliant */
__SDIO_CLEAR_FLAG(SDIOx, SDIO_FLAG_CCRCFAIL);
return SDMMC_ERROR_CMD_CRC_FAIL;
}
Do you have any clue of what is happening ?
Thanks
Vincent
