imx6ul - is there any SW side change needed to enable the biasing circuit for using crystal instead of oscillators [24 Mhz]?

I'm using imx6ul processor. I have changed the hardware to use crystal with internal biasing circuit to work as oscillator.

as per imx6ul RM, when the crystal is identified on the solder bumps, the biasing circuit should be auto enabled. but it is not running it seems. I'm still not seeing desired 24 Mhz in the solder bump when probed with a scope. 

 

Am i missing any SW settings to see the oscillator [with internal biasing circuit enabled] running?

 

any suggestions / guidance is most welcome. Thanks.
