Hello
CodeWarrior for HC12 V4.1 has been generated sometime in 2005. So if your install is dated 2001, it is not V4.1. It is probably a CodeWarrior MOT V1.2 or something like that.
This software package will not support S12XD or any HCS12X CPU.
To support HCS12X CPU family you need to get CodeWarrior for HCS12 V4.5 or V4.6.
