Writing to DDR on BF548

Hi,

I am using the BF 548 Ez kit board.

 

I want to write to a buffer on the DDR at Real time.

My RT samples come from the UART that is configed to work at 4Mbps ( and it is working - checked it).

My sclk is 120Mhz

 

I know that i will not find the problem at UART configurations or the RT SW, because my system can receive samples to a buffer on the DSP.

the problem begins when i set that buffer on the DDR memory.

 

my DDR configurations:

 

*pEBIU_RSTCTL |= 0x0001;
  ssync();

*pEBIU_AMGCTL = 0x0009;
*pEBIU_DDRCTL0 = 0x218A8411;
*pEBIU_DDRCTL1 = 0x20022222;
*pEBIU_DDRCTL2 = 0x00000021;

ssync();

 

 

in all the examples, i couldn't find my problem.

 

What am i doing wrong?
