I have a nice project which I used for demonstrations all over last year.

When I opened it with Codewarrior v6.3, it got automatically converted.

First I have to note, that I had a hard time, getting it built. I had to
undef severals 'inlines' to circumvent
compiler errors, and myriads of

implicite type conversion errors (s.th. like "from * __regabi to *") forced me to undef the MAPI and _MAPI macros.

However now it builts without error. It is a little bit unhappy, since I had to change sources which I were not supposed to do.

This is my persisting problem:
If I download and run the project it stops very early within system initialization, much before getting to main, with a "Bus Error". It is somewhere near copying ROM data. (However it is a RAM project: everything is loaded into the on-chip and on-board RAMs. )

I had similar problems in the past with a MCF54xx project. Some __S_romp arithmetics in the Linker cfg file (stupid non-reproducible trial and error) helped me that time. This time I am not that happy.

Do you have any advice?
