Hi Carsten,
Unfortunately, my target will be STM32. I used the lpc to follow the
wiki. Once I get that working I hope the STM32 will be working also. And
I would like to use fpc 2.7.1 because I know that this version has
enhanced interrupt-handling. I mean, it's easy to use interrupts, at
least, I think, reading the sources of the cross-compiler. I once had a
working STM32 cross-compiler but there you had to be very carefull when
you defined interrupt-routines.
Thanks anyway.
Hi Koenraad
I always write interrupt handling in assembler and then (if necessary) call an
normal pascal
procedure. This way I can controle how stack and memory issues are handled.
I find i hard to believe that the compiler 2.71 can fulfil all your needs in
that area.

Carsten
It can. And quite elegantly if I should say so :)
It now uses weak linking. Try to take a look at some of the Cortex-M*
targets. The ARM RTL's haven't been converted yet, but I see no reason
why they shouldn't be upgraded either. The new solution saves space and
basically can't get any more efficient.
