9.2i EDK, MPMC v3.00a - PLB read burst returns data from incorrect value

Description

When performing a PLB read burst, the last word in the burst returns an earlier address value. How can this burst be corrected?

Solution

This issue has currently been seen only in Virtex-5 designs using 32-word bursts. The last data beat returns the data from two data beats earlier. 

 

There is currently no method by which to work around this issue besides switching to a static-based PHY.  

 

This issue is planned to be fixed in EDK 10.1i. The first MPMC version containing this fix is MPMC v4.00.a.
