关于LMH6401 spi读取id失败的问题

关键程序如下:

//初始化
void SPI_FLASH_Init(void)
{
  SPI_InitTypeDef  SPI_InitStructure;
  GPIO_InitTypeDef GPIO_InitStructure;
	
  
  /* Enable SPI1 and GPIO clocks */
  /*!< SPI_FLASH_SPI_CS_GPIO, SPI_FLASH_SPI_MOSI_GPIO,

       and SPI_FLASH_SPI_SCK_GPIO Periph clock enable */
  /*!< SPI_FLASH_SPI Periph clock enable */
	macSPI_APBxClock_FUN ( macSPI_CLK, ENABLE );
 
  /*!< Configure SPI_FLASH_SPI_CS_PIN pin: SPI_FLASH Card CS pin */
	macSPI_CS_APBxClock_FUN ( macSPI_CS_CLK, ENABLE );
  GPIO_InitStructure.GPIO_Pin = macSPI_CS_PIN;
	GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
  GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP;
  GPIO_Init(macSPI_CS_PORT, &GPIO_InitStructure);
	
  /*!< Configure SPI_FLASH_SPI pins: SCK */
	macSPI_SCK_APBxClock_FUN ( macSPI_SCK_CLK, ENABLE );
  GPIO_InitStructure.GPIO_Pin = macSPI_SCK_PIN;
  GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
  GPIO_Init(macSPI_SCK_PORT, &GPIO_InitStructure);

  /*!< Configure SPI_FLASH_SPI pins: MISO */
	macSPI_MISO_APBxClock_FUN ( macSPI_MISO_CLK, ENABLE );
  GPIO_InitStructure.GPIO_Pin = macSPI_MISO_PIN;
  GPIO_Init(macSPI_MISO_PORT, &GPIO_InitStructure);

  /*!< Configure SPI_FLASH_SPI pins: MOSI */
	macSPI_MOSI_APBxClock_FUN ( macSPI_MOSI_CLK, ENABLE );
  GPIO_InitStructure.GPIO_Pin = macSPI_MOSI_PIN;
  GPIO_Init(macSPI_MOSI_PORT, &GPIO_InitStructure);

  /* Deselect the FLASH: Chip Select high */
  macSPI_FLASH_CS_DISABLE();


  SPI_InitStructure.SPI_Direction = SPI_Direction_2Lines_FullDuplex;
  SPI_InitStructure.SPI_Mode = SPI_Mode_Master;
  SPI_InitStructure.SPI_DataSize = SPI_DataSize_16b;
  SPI_InitStructure.SPI_CPOL = SPI_CPOL_Low;
  SPI_InitStructure.SPI_CPHA = SPI_CPHA_1Edge;
  SPI_InitStructure.SPI_NSS = SPI_NSS_Soft;

  SPI_InitStructure.SPI_CRCPolynomial = 7;//7
  SPI_Init(macSPIx , &SPI_InitStructure);

  /* Enable SPI1  */
  SPI_Cmd(macSPIx , ENABLE);
	
}

//主函数循环读取id

	while(1)
	{
	
	macSPI_FLASH_CS_ENABLE();
	Delay( 1 );
	while (SPI_I2S_GetFlagStatus(macSPIx , SPI_I2S_FLAG_TXE) == RESET);
	SPI_I2S_SendData(macSPIx , 0x0);
	while (SPI_I2S_GetFlagStatus(macSPIx , SPI_I2S_FLAG_RXNE) == RESET);

实测波形图:

sdi发送0x00,返回的典型值应为0x03

请技术大佬分析下为什么没有sdo返回值.

整一个毫无反应的样子. 我看先查硬件吧, 从焊接情况, 供电检查, 还有信号连接和复位等是否都正常.

供电  焊接都测了  并没有什么问题

供电  焊接都测试了  没发现什么问题

你好，问题解决了吗？最近也在调lmh6401，很多地方不懂，可以请教一下吗？
