Similar programs will run on the Stellaris models, but the RAM on those models is severely limited (8KB for LM3S811EVB and 64KB for LM3S6965EVB) and it is hard wired. Having some board that can handle ARMv7-M with more RAM (and can be used with -m) is useful. -- Meador Inge CodeSourcery / Mentor Embedded http://www.mentor.com/embedded-software
