OMAP-L138 SATA: not transmiting data from DMA to system memory .(Code Composer Studio )

Hi,  I am using SATA test code from LogicPD ( BSL code package) and user cases from reference manual. After function :

submitCmd (NON_QUEUED_CMD, cmdSlot2Use);

I am first receiving data, they are copying into memory (prdTableDataBuff [512] ).

Next, i am changing address in Fis and try reading again:

           CmdSlotNum->cfis.DW1.B0LbaLow=myCmdFis.cfisDw1SecNumLbaLow;  //correct address
           CmdSlotNum->cfis.DW1.B1LbaMid=myCmdFis.cfisDw1CylLowLbaMid;
           CmdSlotNum->cfis.DW1.B2LbaHigh=myCmdFis.cfisDw1CylHighLbahigh;
           CmdSlotNum->cfis.DW1.B3Device=myCmdFis.cfisDw1Dev;

           submitCmd (NON_QUEUED_CMD, cmdSlot2Use);

I am getting the correct data block in L1D cache, but not in system memory.

Also, i can change RXABL and TXABL bits in Port DMA Control Register (P0DMACR) , but i can't change RXTS and TXTS (0x4 always!).
