STM32 DMA transfer error - c

Question

I use STM32F407VTG6 controller and try to receive data from SPI using DMA. Then I want to process data on DMA Complete Transfer Interrupt. But when Complete Transfer Interrupt is occurred I see that TEIF (transfer error interrupt flag) is set. After this DMA can't be started. This is part of my code:
static void DmaInit()
{
DMA_InitTypeDef dma;
RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_DMA2, ENABLE);
// DMA for Rx
dma.DMA_Channel = DMA_Channel_3;
dma.DMA_PeripheralBaseAddr = (uint32_t)&SPI1->DR;
dma.DMA_Memory0BaseAddr = 0; // will be set later
dma.DMA_DIR = DMA_DIR_PeripheralToMemory;
dma.DMA_BufferSize = 1; // will be set later
dma.DMA_PeripheralInc = DMA_PeripheralInc_Disable;
dma.DMA_MemoryInc = DMA_MemoryInc_Enable;
dma.DMA_PeripheralDataSize = DMA_PeripheralDataSize_HalfWord;
dma.DMA_MemoryDataSize = DMA_MemoryDataSize_Byte;
dma.DMA_Mode = DMA_Mode_Normal;
dma.DMA_Priority = DMA_Priority_High;
dma.DMA_FIFOMode = DMA_FIFOMode_Disable;
dma.DMA_FIFOThreshold = DMA_FIFOThreshold_HalfFull;
dma.DMA_MemoryBurst = DMA_MemoryBurst_Single;
dma.DMA_PeripheralBurst = DMA_PeripheralBurst_Single;
DMA_DeInit(DMA2_Stream2);
DMA_Init(DMA2_Stream2, &dma);
// Enable DMA Interrupt on complete transfer
NVIC_EnableIRQ(DMA2_Stream2_IRQn);
DMA_ITConfig(DMA2_Stream2, DMA_IT_TC, ENABLE);
}
// It run on external interrupt
static void DmaStart(uint32_t bufferSize, uint32_t* rxBuffer)
{
// Start DMA for reading
DMA2_Stream2->NDTR = bufferSize;
DMA2_Stream2->M0AR = (uint32_t)rxBuffer;
DMA_Cmd(DMA2_Stream2, ENABLE);
}
static void SpiInit()
{
SPI_InitTypeDef spi;
// Enable clock for SPI
RCC_APB2PeriphClockCmd(RCC_APB2Periph_SPI1, ENABLE);
// SPI settings
SPI_StructInit(&spi);
spi.SPI_Direction = SPI_Direction_2Lines_FullDuplex;
spi.SPI_Mode = SPI_Mode_Master;
spi.SPI_DataSize = SPI_DataSize_8b;
spi.SPI_CPOL = SPI_CPOL_Low;
spi.SPI_CPHA = SPI_CPHA_2Edge;
spi.SPI_NSS = SPI_NSS_Soft;
spi.SPI_BaudRatePrescaler = SPI_BaudRatePrescaler_16;
spi.SPI_FirstBit = SPI_FirstBit_MSB;
SPI_Init(SPI1, &spi);
SPI_Cmd(SPI1, ENABLE);
SPI_I2S_DMACmd(SPI1, SPI_I2S_DMAReq_Rx, ENABLE);
}

I just finished my SDIO+DMA this days, some notes maybe useful for you:
Clear Flags before enabling the stream
DMA_ClearFlag(DMA2_Stream2, DMA_FLAG_FEIF2|DMA_FLAG_DMEIF2|DMA_FLAG_TEIF2|DMA_FLAG_HTIF2|DMA_FLAG_TCIF2);
Clear EN bit in the DMA_SxCR Register, Wait Until the EN bit is read as 0 before DMA_Init()
DMA_Cmd(DMA2_Stream2, DISABLE);
while (DMA2_Stream2->CR & DMA_SxCR_EN);
When use DMA_FIFOMode_Disable (Direct Mode), data width is determined by DMA_PeripheralDataSize (PSIZE), DMA_MemoryDataSize (MSIZE) is ignored
Memory address must be aligned to your selected data width (HalfWord)
