AR# 33324 11.2 EDK, XPS_MCH_EMC - MicroBlaze hangs when C_DCACHE_ALWAYS_USED=1

Description

Keywords: freeze, corrupt, EMC, XCL2

When using an XPS_MCH_EMC through an XCL2 port, a byte transaction followed by a burst with the same address will cause the XCL2 interface to signal incorrectly. In a MicroBlaze system, this can cause a processor hang. How do I resolve this issue?

Solution

This issue is fixed in xps_mch_emc_v3_01_a, to be released in EDK 11.3.
