I could not really find a difference in what you are doing to what I am
doing so perhaps I give you my commandlines for the build, perhaps the
difference is in the way you build:
Build&Install the compiler (in Cortex-M3 Mode)
make clean buildbase CROSSINSTALL=1 OS_TARGET=embedded CPU_TARGET=arm
*SUBARCH=armv7m* CROSSOPT="-O- -gw2" BINUTILSPREFIX=arm-none-eabi- || exit 1
sudo make installbase CROSSINSTALL=1 OS_TARGET=embedded CPU_TARGET=arm
SUBARCH=armv7m CROSSOPT="-O-" BINUTILSPREFIX=arm-none-eabi- || exit 1
Build&Install the compiler (in Cortex-M4 Mode)
make clean buildbase CROSSINSTALL=1 OS_TARGET=embedded CPU_TARGET=arm
*SUBARCH=armv7em* CROSSOPT="-O- -gw2" BINUTILSPREFIX=arm-none-eabi- ||
exit 1
sudo make installbase CROSSINSTALL=1 OS_TARGET=embedded CPU_TARGET=arm
SUBARCH=armv7em CROSSOPT="-O-" BINUTILSPREFIX=arm-none-eabi- || exit 1
This gives me a compiler that works for compiling:
/usr/local/lib/fpc/2.7.1/ppcrossarm -MObjFPC -Scghi -al -Ch1024 -Cs1024
-Tembedded -Parm -gw2 -godwarfsets -godwarfmethodclassprefix -vewnhixv
-l -Cparmv7m *-WpSTM32F407VG* -XParm-none-eabi- -FD/usr/local/bin -a
peephole.pas
I usually compile for Cortex-M4 in Cortex-M3 Mode, this makes life a
little easier when you do not need the features of armv7em.
The reason for this is that currently fpc cannot distinguish between
different subarchs and I do not want to have several installations of
ppcrossarm on my machine as long as I do not need the special armv7em
features.
Please have a look at the rtl-files I provide (and tell me if you like
the way I created them) , they are automagically created out of the
CMSIS sources provided by ARM&ST.

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:

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,
Sietse
