Thanks for your help! (Nearly) everything works fine now. One of the left
problems deals with breakpoints inside gdb. We can set breakpoints but the
program doesn't stop. If we stop the program with the "stop" button inside
Insight the program stops but hangs if we step through the code after that.
Maybe this problem is related with the (probably missing) v850.hex code
inside the internal flash? What is the function of this code? Because we're
still waiting for a flasher tool for the v850 we couldn't program it yet.

Another question: Are there any other ports for the v850 architecture? There
is another V850 eval board called "startWARE Starterkit" from NEC which we're
interested in. Are there any ongoing (or completed) porting efforts towards
this board?
