Hi,
If you use DSP56800E(MC56F83xx, MC56F801x, MC56F803x, MC56F8006, MC56F82xx) or DSP56800EX(MC56F81xxx, MC56F82xxx, MC56F83xxx, MC56F84xxx), I suggest you use the CodeWarrior for MCU ver11.x.
This is the link:

As far as I know that the CodeWarrior for MCU ver11.x. tools for DSC is free of charge.
You can download a free trial license.
Hope it can help you
