MicroBlaze v3.00a and 4.00a - Cache corruption when utilizing the CacheLink (XCL) interface

描述

Keywords: EDK, WIC, WDC, instruction

Urgency: Standard

General Description:
In EDK 6.3 and 7.1, when the MicroBlaze v3.00a and v4.00a have been configured to use the CacheLink (XCL) cache interfaces, corruption of cache data occurs while performing a partial invalidation of CacheLink caches (i.e., writing part of the cache with WIC or WDC instructions).

解决方案

Always perform full invalidation of the cache (e.g., using macros microblaze_init_dcache_range and microblaze_init_icache_range where the range is set to the size of the respective cache).
