Hello
I have checked with product management and indicated we are missing Kinetis specific information for the various editions.
Basically, special edition comes with a size limitation of 128 K. Meaning you can build ANSI C application with up to 128 K of code and data.
Standard edition allows to develop ANSI C application without any limitation in size ANSI C source code.
Professional edition allows you to develop ANSI C & C++ application without any size limitation.
Note that if you are using MQX OS, only the professional edition comes with support for MQX kernel awareness in the debugger.
I hope this helps.
