PetaLinux 2014.2 - MicroBlaze D-Cache in Writeback Mode Causes No Output in FS-BOOT Application

描述

My MicroBlaze-based system configured the D-cache to use writeback mode. 

In this configuration, I see no output from the FS-BOOT application.

解决方案

Using writeback with the D-cache prevents the API call XCACHE_DISABLE_CACHE() from working.

This API call is commonly used in standalone applications. 

To allow FS-BOOT to output to the console, disable writeback mode for the D-cache.
