Ulrich, 

I am getting lost...

What I did:

Compile various gcc for arm-eabi, e.g. from crosstool-NG. 
Link ~/bin/arm-gcc tp the resulting gcc-xxx-eabi-yyy binary
nut/tools/nutconf/nutconfigure -bcomstick -cnut/conf/stm32-comStick.conf \
                               -lcomstick -marm-gcc create-buildtree
cd comstick
make
make -C arch

Any hints what I do wrong? 
A also have  a Win machine. How do I start STM32 development there?

Thanks
