We are trying to use the MM9Z1_638 in a new battery management system design. Our battery models are currently designed in Simulink, and we would like to develop the rest of the system in Simulink as well. I know that in the Hardware Implementation menus in Simulink I can choose Freescale (NXP) S12X, but that essentially only adjusts data type sizes. I'm looking for something slightly more integrated, and specifically for the S12Z (the MCU core on the MM9Z1). Is there a toolchain available to do this? NXP/Freescale or 3rd party?
