Freescale M9S12
Freescale M68HCS12
MC9S12NE64. Support for the MC9S12NE64 MCU and two boards are included:
The Freescale DEMO9S12NE64 Evaluation Board, and
The Future Electronics Group NE64 /PoE Badge board.
Both use a GNU arm-nuttx-elf toolchain* under Linux or Cygwin. The NuttX buildroot provides a properly patched GCC 3.4.4 toolchain that is highly optimized for the m9s12x family.
