AM3359 UART Baudrate

I'm configuring the /dev/ttyO1 of the AM3359 with the function below. Irrespective the value put in cfsetospeed and cfsetispeed the baud rate is always 9600. Has someone seen this issue?

bool InitPortSettings(int pValidDescriptor)
{
    if (m_currentSerialState != SERIAL_READY)
    {
        printf ("Error: Cannot initialize port settings. Invalid state.");
        return false;
    }
    
    tcgetattr(pValidDescriptor,&m_oldPortSettings);
    bzero(&m_newPortSettings, sizeof(m_newPortSettings));
    
    /* Initial baudrate is 9600... If needed, change it through SetSerialSpeed() function */
    if (cfsetispeed(&m_oldPortSettings, B115200) == 0)
    {
        __android_log_print(ANDROID_LOG_INFO,LOG_TAG,"Velocidade de entrada configurada!");
    }
    if (cfsetospeed(&m_oldPortSettings, B115200) == 0)
    {
        __android_log_print(ANDROID_LOG_INFO,LOG_TAG,"Velocidade de saída configurada!");
    }
    
    // Consultar aqui para detalhes http://www.easysw.com/~mike/serial/serial.html

    m_oldPortSettings.c_cflag         = CS8 | PARENB | CREAD | CLOCAL ;
    m_oldPortSettings.c_lflag         &= ~(ICANON | ECHO | ECHOE | ISIG);
    m_oldPortSettings.c_cc[VTIME]     = 2; //inter-char timer
    m_oldPortSettings.c_cc[VMIN]    = 0; //block until 8 chars received
    m_oldPortSettings.c_oflag         &= ~OPOST;
    m_oldPortSettings.c_iflag         |= (INPCK | ISTRIP);
        
    if (tcflush(pValidDescriptor, TCIOFLUSH) != 0)
    {
        printf("Warning: Problem when flushing serial port");
    }
    
    tcsetattr(pValidDescriptor, TCSANOW, &m_oldPortSettings);
    m_currentSerialState = SERIAL_INITIALIZED;

    __android_log_print(ANDROID_LOG_INFO,LOG_TAG,"Porta serial configurada");

    return true;
