I have an old hardware based on MC9S12A512... but have lost old CW suite to develop with it.
Downloading/installing CW for HCS12(X) v5.2, have found this family not supported.
What possibility i have to write/compile new code for it?
you can still download and use CW v5.1.
We also do not use 5.2.
Look at this How to find CodeWarrior v5.1 for S12(X) MCUs (Classic IDE) download
I think it will solve all your issues.
