I mean when I try to enable external xtal by 

NRF_CLOCK->TASKS_HFCLKSTART=1;

but  

while (NRF_CLOCK->EVENTS_HFCLKSTARTED == 0);   //

cannot run out of this.

the datasheet is:

yxc_3225_4p.pdf

thanks for your help..

the xtal signal is like:

the voltage range from 0.3v to 0.7v

would it be ok?
would you please show the signal in DK?  I cannot get the xtal signal from DK.

thanks.
