CRC-32 for STM32L4 calculate from HAL_CRC_Calculate(); function

Question

As CRC Configuration below

      hcrc.Instance = CRC;
      hcrc.Init.DefaultPolynomialUse = DEFAULT_POLYNOMIAL_ENABLE;
      hcrc.Init.DefaultInitValueUse = DEFAULT_INIT_VALUE_ENABLE;
      hcrc.Init.InputDataInversionMode = CRC_INPUTDATA_INVERSION_NONE;
      hcrc.Init.OutputDataInversionMode = CRC_OUTPUTDATA_INVERSION_DISABLE;<br>
      hcrc.InputDataFormat = CRC_INPUTDATA_FORMAT_BYTES;
      if (HAL_CRC_Init(&hcrc) != HAL_OK)
      {
        Error_Handler();
      }

Polynomial state : default (MPEG-2 : 0x04C11DB7)
Value stage : default (MPEG-2 : 0xFFFFFFFF)
The result data calculate from HAL_CRC_Calculate(...); is 0xD2AEA5A1

      uint32_t data[2]={0x01, 0x01};
      uint32_t crc_cal;
      crc_cal = HAL_CRC_Calculate(&hcrc, data, 2);
      sprintf(VariableDebug,"CRC Value (HAL_CRC Cal.) %08X, ",crc_cal);
      PRINT_MSG_CYAN(VariableDebug);

It's not the same as data from CRC online is 0xD66FB816 as Link below

Could you please help me solve this problem?

Change this:

uint32_t data[2]={0x01, 0x01};
uint32_t crc_cal;
crc_cal = HAL_CRC_Calculate(&hcrc, data, 2);

To this:

uint8_t data[]={0x01, 0x01};
uint32_t crc_cal;
crc_cal = HAL_CRC_Calculate(&hcrc, (uint32_t*)data, 2);

For good practice, you can also use sizeof(data) instead of 2.
