ADSP-BF706 - SPI1 DMA

I'm trying to make SPI1 via DMA work, but I don't see the signals on the oscilloscope, it doesn't work, it could help me. Here is the code:

boot:
void Init_SPI1(void)
{
/*
*pREG_SPI1_CLK = ( ( 9 << BITP_SPI_CLK_BAUD) & BITM_SPI_CLK_BAUD);

*pREG_SPI1_DLY = ( ((1 << BITP_SPI_DLY_STOP) & BITM_SPI_DLY_STOP) |
((1 << BITP_SPI_DLY_LEADX)& BITM_SPI_DLY_LEADX) |
((1 << BITP_SPI_DLY_LAGX) & BITM_SPI_DLY_LAGX) );

*pREG_SPI1_CTL = ( ((SPI1_MSTR << BITP_SPI_CTL_MSTR) & BITM_SPI_CTL_MSTR) |
((CPHA << BITP_SPI_CTL_CPHA) & BITM_SPI_CTL_CPHA ) |
((CPOL << BITP_SPI_CTL_CPOL) & BITM_SPI_CTL_CPOL ) |
((SPI_SIZE << BITP_SPI_CTL_SIZE) & BITM_SPI_CTL_SIZE ) |
((LSBF << BITP_SPI_CTL_LSBF) & BITM_SPI_CTL_LSBF ) |
BITM_SPI_CTL_ASSEL | BITM_SPI_CTL_SELST );


*pREG_SPI1_TXCTL = (ENUM_SPI_TXCTL_TWC_EN | ENUM_SPI_TXCTL_ZERO | ENUM_SPI_TXCTL_TDR_50 );

*pREG_SPI1_TWC = BUFF_SIZE;

*pREG_SPI1_TWCR = 0x00;

*pREG_SPI1_SLVSEL = (ENUM_SPI_SLVSEL_SSEL1_EN);
*/
*pREG_SPI1_CLK = 24;
*pREG_SPI1_DLY = 0; //((1 << BITP_SPI_DLY_STOP) & BITM_SPI_DLY_STOP) ;
*pREG_SPI1_SLVSEL= ENUM_SPI_SLVSEL_SSEL1_HI | ENUM_SPI_SLVSEL_SSEL1_EN;

*pREG_SPI1_CTL = ENUM_SPI_CTL_MASTER ;
*pREG_SPI1_TXCTL = ENUM_SPI_TXCTL_TTI_EN | ENUM_SPI_TXCTL_TWC_EN | ENUM_SPI_TXCTL_ZERO ;
*pREG_SPI1_RXCTL = ENUM_SPI_RXCTL_OVERWRITE ;

*pREG_SPI1_TXCTL |= ENUM_SPI_TXCTL_TX_EN; // enable Tx SPI
*pREG_SPI1_RXCTL |= ENUM_SPI_RXCTL_RX_EN; // enable Rx SPI
*pREG_SPI1_CTL |= ENUM_SPI_CTL_EN;
}

return 0;
}

Transmitter:
*pREG_SPI1_SLVSEL &= ~ENUM_SPI_SLVSEL_SSEL1_HI ; // select device

while(!(*pREG_SPI1_STAT & BITM_SPI_STAT_RFE)) *pREG_SPI1_RFIFO;

*pREG_SPI1_TWC = 1; // single byte instruction, no addr/data
*pREG_SPI1_TFIFO = 0xAA; // command ID
while(!(*pREG_SPI1_STAT & BITM_SPI_STAT_TF)); // wait till completion
*pREG_SPI1_STAT = BITM_SPI_STAT_TF; // clear latch
while(*pREG_SPI1_STAT & BITM_SPI_STAT_RFE);

*pREG_SPI1_SLVSEL |= ENUM_SPI_SLVSEL_SSEL1_HI ; // select device

But SPI1 does not work, can help or
opinion?

Thanks!
