Hi,
CW 5.6 is not a CodeWarrior for DSC version but the version of the IDE.
I think you want to move DSP 7.x to DSC 8.x.
The upgrade is not free.
However this depens of the license used (special, ...).
By default the CodeWarrior installation has a special edition license (free).
No if you need another version, you must contact your local Freescale distributor for details.
See info to download the DSC 8.x
