求教 MSP430FR5739+CC3000

你好，我在用TI提供的CC3000的例程在调试Wi-Fi的时候发现程序总是死在SPI.c 中 while (sSpiInformation.ulSpiState != eSPI_STATE_INITIALIZED) 这里，大概是哪里的原因，谢谢！ 

long SpiWrite(unsigned char *pUserBuffer, unsigned short usLength)
{
    unsigned char ucPad = 0;

	//
	// Figure out the total length of the packet in order to figure out if there is padding or not
	//
    if(!(usLength & 0x0001))
    {
        ucPad++;
    }


    pUserBuffer[0] = WRITE;
    pUserBuffer[1] = HI(usLength + ucPad);
    pUserBuffer[2] = LO(usLength + ucPad);
    pUserBuffer[3] = 0;
    pUserBuffer[4] = 0;

    usLength += (sizeof(btspi_hdr) + ucPad);

	if (sSpiInformation.ulSpiState == eSPI_STATE_POWERUP)
	{
		while (sSpiInformation.ulSpiState != eSPI_STATE_INITIALIZED)
			;
	}
