In the early days of Neutrino 1.0 and 2.0 I believe there was NON MMU versions. I can only speculate as to why it was
abandoned. Maintaining a MMU and NON MMU version while maintaining compatibility would required lots of work. Not to
mention the enormous number of micro controller model out there to support.
Micro controler have a very different set of requirement, I don't think libc.so at 665k would be a great fit ;-)
