KW21Z Memory Map Inconsistency

In the reference manual, it indicates that the KW41Z/31Z/21Z all have their RAM region start at 0x1FFF8000. The linker scripts generated for the KW21Z 256/64 when using MCUXpresso uses 0x1FFFC000 instead. Linker scripts generated for the KW41Z have RAM at the expected 0x1FFF8000. My application hits a hard fault immediately if I change this to 0x1FFF8000 as mentioned in the reference manual.


Why is this different for the KW21Z 256/64? Does this mean the amount of available RAM is less than 64KB?


Thanks for any insight you can give.
