12.2 EDK, MicroBlaze - WIC fails to invalidate instruction cache

Description

MicroBlaze processor may fail to invalidate instruction cache with a WIC instruction when the victim cache is enabled. How do I resolve this issue?

Solution

This issue only affects MicroBlaze processor versions v7.30.a and v7.30.b when C_ICACHE_VICTIMS is greater than 0. Setting C_ICACHE_VICTIMS to 0 will work around it.

This issue is fixed in MicroBlaze processor v8.00.a, released in EDK 12.3.
