Hi
Thanks for your help.. but i did get it to work.. but I still dont 
know what i was doing wrong.. but this is how i solved it...

for all C-files im using i added "-mthumb-interwork" command to the 
gcc-compiler. Then the code that is generated can handel calls 
between ARM och THUMB code.

Now i can go home from work today and feel happy  =)...

Until next time... bye
