CW7 56800/E - External cristal does not work

I've got a problem with the setting of the external cristal in a CodeWarrior-project (7.0) for 56800/E Hybrid Controllers. I'm using the Freescale development board MC56F8323EVM with processor expert. I programmed a application with a timer interrupt (1ms). A counter counts until 250 and then it changes a GPIO-Pin -> blinking LED. Anyway, if I set the Clock source to On-chip relaxations oscillator and afterwards try to debug the project, it behaves normaly. When I set the Clock source to External crystal and try to debug the project, it does'nt stop on entry point and the LED does'nt blink anymore!?
