ST25TAGS_TVC_OpenSecuritySession Fails when trying to open a CONFIGURATION_SECURITY_SESSION

[AC_E]

Hello ST Community,

I am using a STEVAL-25R200A to do tests with the ST25TV02KC.

I am trying to rfalST25xVPollerPresentPassword, with a pwdNumber of 0x00 to enter Configuration Session (As described in the nfc tag datasheet), But keep getting error 5, even though I am passing the default 32-bit password.
I am using this function:

ReturnCode ST25TAGS_TVC_OpenSecuritySession(const uint8_t * uid, ST25TAG_TVC_SecuritySession_t sessionType,
        const uint8_t * pPassword)
{
    uint8_t     pwdNumber;
    uint8_t     pwdLengthInBytes = 4;
    ReturnCode  errCode;
    uint8_t     rxBuf[ 1 + 2 + 2 ];    /* Flags + Random Number Data + CRC */;
    uint16_t    rcvLen;
    uint8_t     updatedPassword[8];

    switch (sessionType)
    {
        case CONFIGURATION_SECURITY_SESSION:
            pwdNumber = 0;
            break;
        case USER_AREA1_SECURITY_SESSION:
            pwdNumber = 1;
            break;
        case USER_AREA2_SECURITY_SESSION:
            pwdNumber = 2;
            break;
        case SINGLE_USER_AREA_SECURITY_SESSION:
            pwdLengthInBytes = 8;
            pwdNumber = 1;
            break;
        case UNTRACEABLE_SECURITY_SESSION:
            pwdNumber = 3;
            break;
        default:
            return RFAL_ERR_PARAM;
    }

    // Encrypt password
    // 1. Get Random Number
    errCode = rfalST25xVPollerGetRandomNumber( ST25TAGS_TVC_REQ_FLAG, uid, rxBuf, sizeof(rxBuf), &rcvLen );

    if ( errCode == RFAL_ERR_NONE )
    {
        // 2. XOR random number with given password located in rxBuf[1] and rxBuf[2]
        for (uint8_t i = 0; i < (pwdLengthInBytes * 2); i++)
        {
            updatedPassword[i] = pPassword[i] ^ rxBuf[2 - (i + 1) % 2];
        }

        // Present password
        errCode = rfalST25xVPollerPresentPassword( ST25TAGS_TVC_REQ_FLAG, uid,
                pwdNumber, updatedPassword, pwdLengthInBytes);
    }

    // Same ReturnCode definitions used in st_errno.h of RFAL
    return errCode;
}

And calling it like this:

uint8_t plainPwd[4] = {0x0, 0x0, 0x0 ,0x0}; 
err = ST25TAGS_TVC_OpenSecuritySession(uid, CONFIGURATION_SECURITY_SESSION, plainPwd);
platformLog(" Present password: %s Error Code: %d \r\n", (err != RFAL_ERR_NONE) ? "Fail" : "OK", (err != RFAL_ERR_NONE) ? err : 0);

But i get this error code:
Present password: Fail Error Code: 5

I would appreciate your help,

Thank you
