Hello Franz,
That's true that all it's not very straight forward.
Because TBDML is a new thing, it is not included in CodeWarrior natively.
However the CodeWarrior team is taking this into account as I think they already included the OSBDM08 (for (R)S08) as standard target in CW for S08 v.5.
Hopefully it means that the next revision or Service Pack of CW S12 v4.5 will include the TBDML as native as well.
May be our Dear CrazyCat has an insider input on this
Anyway, DO FEEL free to ask your questions, there are a lot of people here eager to help !!!
Cheers,
Alban.
