TMS320c6424 McBSP 16bit data transfer at high frequencies

Prodigy 170 points

Hi,

I am trying to send data by using McBSP in standart operation but when I configured the McBSP of c6424(500MHz) to 16 bit word length and higher than a 30MHz frequency I encounter data repeats on the receive side. for lower frequencies there is no such problem. I used L1D ram for servicing McBSP but it didnt solved the problem. In erreta of the c6424 it tells about the problem about 8 bit word length. Am I missing something ? (I am using edma to service McBSP)

here is my configurations ,

RCR     = 0x00041440;
XCR     = 0x00041440;
MCR     = 0x00000000;
PCR     = 0x00000A00;
SRGR     = 0x34000F01;
SPCR     = 0x00F08030;

Thnx.
