    KIT-059 Crystal issue: no XTAL output


      I must be doing something wrong, but I just cannot see it.


      I am trying to add an external crystal of 20Mhz (I had these laying around). I configure the XTAL block in the design wide resources but the best I can do is ending up in the halt-on-clock-error: while(1) code. I have tried to measure the XTAL_OUT with a scope - with and without the external crystal but it is always low as is the XTAL_IN pin. I have no other external components as the kit board already has two 22pf caps on these pins.


      I have also played with the XTAL configuration settings, timeout etc. Nothing seems to help.


      Is there a trick to this?
