STM32F4 I2S slave Receive with DMA

Hello!
I try to receive data by I2S3 in slave mode.
First of all I tried to program I2S controller and received data by program polling:
 while(1){
    while( (SPI3->SR & SPI_I2S_FLAG_RXNE) == 0 );
    SPDiffRxBuffer[TimeRXPointer][0] = (long)SPI3->DR;
    if( ++TimeRXPointer >= SPDIFF_BUF_LEN ) TimeRXPointer = 0;
  }
Second, I add function to use DMA
static void I2S_DMA_Init( void )
{
  DMA_InitTypeDef DMA_InitStruct;
  NVIC_InitTypeDef   NVIC_InitStructure;
 
  DMA_DeInit( DMA1_Stream2 );

  RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_DMA1, ENABLE);

  DMA_InitStruct.DMA_Channel = DMA_Channel_2;
  DMA_InitStruct.DMA_PeripheralBaseAddr = (uint32_t)&(SPI3->DR);
  DMA_InitStruct.DMA_Memory0BaseAddr = (uint32_t)SPDiffRxBuffer;
  DMA_InitStruct.DMA_DIR = DMA_DIR_PeripheralToMemory;            
  DMA_InitStruct.DMA_BufferSize = SPDIFF_BUF_LEN * 4;          
  DMA_InitStruct.DMA_PeripheralInc = DMA_PeripheralInc_Disable;
  DMA_InitStruct.DMA_MemoryInc = DMA_MemoryInc_Enable;          
  DMA_InitStruct.DMA_PeripheralDataSize = DMA_PeripheralDataSize_HalfWord;
  DMA_InitStruct.DMA_MemoryDataSize = DMA_MemoryDataSize_HalfWord;     
  DMA_InitStruct.DMA_Mode = DMA_Mode_Circular;                 
  DMA_InitStruct.DMA_Priority = DMA_Priority_High;            
  DMA_InitStruct.DMA_FIFOMode = DMA_FIFOMode_Enable;          
  DMA_InitStruct.DMA_FIFOThreshold = DMA_FIFOThreshold_HalfFull;
  DMA_InitStruct.DMA_MemoryBurst = DMA_MemoryBurst_INC4;          
  DMA_InitStruct.DMA_PeripheralBurst = DMA_PeripheralBurst_Single;
  while( DMA_GetCmdStatus( DMA1_Stream2 ) == ENABLE );
  DMA_Init( DMA1_Stream2, &DMA_InitStruct );

  DMA_ITConfig( DMA1_Stream2, DMA_IT_TC, ENABLE );

  DMA_Cmd( DMA1_Stream2, ENABLE );
 
  SPI_I2S_DMACmd( SPI3, SPI_I2S_DMAReq_Rx, ENABLE);

  NVIC_InitStructure.NVIC_IRQChannel = DMA1_Stream2_IRQn;
  NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0x01;
  NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0x01;
  NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
  NVIC_Init(&NVIC_InitStructure);
}
and interrupt funtion
void DMA1_Stream2_IRQHandler( void )
{
  LEDOn( LED1 );
  LEDOff( LED1 );
}
But IRQ not executed and data not filled array SPDiffRxBuffer. Bit RXNE is set and I can read data in polling. But not by DMA. What I write wrong?

Addition: error in RM0090.

27.4.6 I2S slave mode
Point:
Reception sequence
Error text:
The operating mode is the same as for the transmission mode except for the point 1 (refer to
the procedure described in Section 27.4.6: I2S slave mode), where the configuration should
set the master reception mode using the I2SCFG[1:0] bits in the SPI_I2SCFGR register.
