}

There is a function in - SDMMC_GetCmdResp1(SD MMC x, SD MMC_CMD_UP_CMD, SD MMC_CMD TIMEOUT);

When the Sdmmc->STA register is checked in the body of this function, the check takes a very long time, since the CMDACT bit is in one. After 20-30 seconds, the bit is reset and the card works perfectly. Tellingly, the initialization time may be shorter, sometimes everything passes at once.

4-bit mode, 48 MHz frequency.

How to fix?

P.s. I tested with a debugger that where fail the program. Inside of the SD_PowerON function exist a while loop. When the cards don't recognize this while loop run infinitelly and never go out from there.

/* Send ACMD41 SD_APP_OP_COND with Argument 0x80100000 */
 
while(validvoltage == 0)
 
{
 
  if(count++ == SDMMC_MAX_VOLT_TRIAL)
 
  {
 
    return HAL_SD_ERROR_INVALID_VOLTRANGE;
 
  }
 
 
 
  /* SEND CMD55 APP_CMD with RCA as 0 */
 
  errorstate = SDMMC_CmdAppCommand(hsd->Instance, 0);
 
  if(errorstate != HAL_SD_ERROR_NONE)
 
  {
 
    return HAL_SD_ERROR_UNSUPPORTED_FEATURE;
 
  }
 
 
 
  /* Send CMD41 */
 
  errorstate = SDMMC_CmdAppOperCommand(hsd->Instance, SDMMC_STD_CAPACITY);
 
  if(errorstate != HAL_SD_ERROR_NONE)
 
  {
 
    return HAL_SD_ERROR_UNSUPPORTED_FEATURE;
 
  }
 
 
 
  /* Get command response */
 
  response = SDMMC_GetResponse(hsd->Instance, SDMMC_RESP1);
 
 
 
  /* Get operating voltage*/
 
  validvoltage = (((response >> 31) == 1) ? 1 : 0);
 
}
