You need to change two files,

Thanks Florian van Michael,
You can find the files I changed on
http://fwn06.housing.rug.nl/fpc-stm32f4
There you find the above files, the Makefile.fpc from rtl/embedded and
the new files in rtl/embedded/arm.
The diff from cpuinfo.pas with current trunk is:
*** tmp/fpc/compiler/arm/cpuinfo.pas 2014-11-30 11:59:12.008103356 +0100

Looks alright to me.

Also ok?
I think the error has to come from one of these files, not the contents of the
rtl itself.
The rtl code is still rather rough, but it compiles.
I have already done that work, I can send you a patchfile for trunk that adds
the following devices:
That would be nice,
Thanks,
