32 MHz External Crystal not working

[Austinag]

We have developed a custom board with an external 32 MHz Crystal but I am having trouble initializing everything correctly.  With the Zephyr "Hello World" example code I can only get it to run on the custom board if I set 

CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC=y

in my prj.conf file.  My understanding for all I need to do in order to use the external oscillator is set the following:

CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC=n
CONFIG_CLOCK_CONTROL_NRF_K32SRC_XTAL=y

When I do this not even the "Hello World" executes although everything builds and flashed with no warnings/errors.  Are there other steps I need to follow?  The schematic for this board is extremely simple seen here:

The data sheet for the Crystal can be read here:

IDE: NRF CONNECT for VS Code

In case you need a quick (unofficial) reply, note that you do not have a 32kHz crystal fitted and K32SRC_XTAL refers to that missing 32kHz crystal. The 32MHz crystal which is fitted is not handled by that config, and so using K32SRC_RC=y is the correct option.

The 32kHz crystal would be a separate crystal fitted to P0.00 and P0.01

Thank you for the quick response I am just now realizing K2 is MHz not kHz and everything is making sense now.  I was hoping to reduce idle power by using an external 32 kHz crystal but it appears that would need a redesign.

Again, thank you for pointing out my silly mistake!  I would have been scratching my head on this for a while.
