OK, but in general, soft-float emulation should be used on systems
without FPU and this is even more important for real-time. This is a
tool chain issue. Niklaus, what tool chain are you using?
You seem to need that because your compiler generates code with hard FP
instructions. You could check this with:
$ ppc-linux-objdump -d prog|egrep ":\s*[e-f]"
The toolchain is gcc-3.4.4-glibc-2.3.5/powerpc-405-linux-gnu built using Dan
Kegel crosstool (Version 0.42 if I remember exactly).
Shall I switch to another one?
The ELDK from DENX uses FP soft-emulation for 4xx (http://www.denx.de).
Choose v3.1.1 for Linux 2.4 and v4 for Linux 2.6.
