Problems regarding Xtal function on MC908AP

I have been programming MC908APCFAE microcontroller, using the CodeWarrior dev. tools and FSICEBASE platform.

 

The hardware is functioning correctly when connected to the development tool through the MON08 cable and the development tool is generating the clock signal. 

 

As soon as I try to run the target by it´s own Xtal the oscillating circuit does not oscillate. 

 

Note should be taken that when the external clock signal  from the development tool is applied to the OSC1 pin, no inverted signal is detected at the OSC2 output.

 

Hope someone can help

 

Regards
