Driving the lfclk with clkout signal from a peripheral

Hi All, 

I am trying to drive the low freq clock necessary for the softdevice on an nrf52832 (sd s132 ver 6.1.1) with the clkout signal from an i2c real-time-clock peripheral thats on a custom board I have. The rtc has the 32kHz crystal attached to it and the clkout signal from that ship is set to output the same 32kHz signal by default over the clkout pin. This pin is hooked up to P0/XL1 on the nrf52832 chip. When I run my application the cpu enters the sd_softdevice_enable() function and then never seems to come back, I set break points right after that function gets called but they are never reached. Is there something I need to do in particular to configure the chip to use the clkout signal coming from another chip? Is it getting confused because the "crystal" it assumes is there is not being driven yet by the XL2 pin but output is still being received?

As usual, any and all insight is appreciated!

Best,

Patrick
