我在国民技术的开发板上移植GH3026模块的库，主控是国民的N32G452，选择的通讯方式是SPI，在调用汇顶提供的SDK v4300里面提供的demo，Gh3x2xDemoInit()函数-》GH3X2X_Init()函数里面尝试唤醒芯片时总是失败，读取寄存器0x0036里面的内容是0xf100，却不是0xaa55，请问这个是什么原因呢？？

国民的sip初始化如下：

GPIO_InitType GPIO_InitStructure;

/*!< GPIO Periph clock enable */

/*!< SPI1 Periph clock enable */

RCC_EnableAPB2PeriphClk(RCC_APB2_PERIPH_SPI1, ENABLE);

/**SPI1 GPIO Configuration

GPIO_InitPeripheral(GPIOB, &GPIO_InitStructure);

/* Configure the SPI1 pin: SPI_INT */

GPIO_InitStructure.Pin = GPIO_PIN_2;

GPIO_InitPeripheral(GPIOB, &GPIO_InitStructure);

/*!< SPI configuration */

SPI_InitStructure.NSS = SPI_NSS_SOFT;

SPI_InitStructure.BaudRatePres = SPI_BR_PRESCALER_16;

SPI_InitStructure.FirstBit = SPI_FB_MSB;

SPI_InitStructure.CRCPoly = 10;

SPI_Init(SPI1, &SPI_InitStructure);

/*!< Enable the SPI1 */

SPI_Enable(SPI1, ENABLE);

}

GU8 hal_gh3x2x_spi_write(GU8 write_buffer[], GU16 length)

{

ret = SPI1_ReadWriteByte(write_buffer[0]);

return ret;

}

{

return SPI_I2S_ReceiveData(SPI1);

}

// SPI1 读写一个字节

// TxData:要写入的字节

//返回值:读取到的字节

GU8 SPI1_ReadWriteByte(GU8 TxData)

{
