    This error means that you have something (IRAM) allocated in your memory section manager of BIOS that is allocated over the space now being used by cache. To fix this you need to go into the memory section manager and adjust the properties of IRAM such that it is of a size and starting location that it is not allocated into the space that you just turned to cache.

    Moving your code/data segments to DDR2 may be a step you need to take if you need to free up space in IRAM so it can be adjusted to fit along side the cache space, however just moving the code/data alone is not enough, the build system is not smart enough to realize there is empty space in IRAM to the point that it would no longer overlap with the cache, you must redefine IRAM yourself.
