9.2i EDK - OPB_SDRAM_v1_00_e issues incorrect read or write transaction after row-crossing burst

Description

After performing a burst transaction to OPB_SDRAM, the next transaction is incorrect. The next transaction is either a read instead of a write, or a write instead of a read.  

 

How do I resolve this?

Solution

This issue is not planned to be fixed. Upgrading the entire system to a MPMC-based design will also avoid this issue.
