8.1i EDK, OPB DDR - An OPB_DDR test routine fails when the PowerPC cache is enabled

Description

My system hangs when a Burst Read is triggered by a Cache Line Read over the PLB2OPB bridge requested by the PowerPC; the system also hangs when the Burst Read is triggered using the OPB Central DMA. 

 

In the MHS, the PARAMETER C_INCLUDE_BURST_SUPPORT = 1 is set.

Solution

This problem has been fixed in core included in the latest EDK 8.1i Service Pack, available at:

The first service pack containing the fix is EDK 8.1i Service Pack 1.
