Getting internal clocks to run on NRF54l15

[jgarv743]

Been trying to set up a project to run some basic openthread as a proof of concept project. I based much of it off the CLI example and SDK. I have gotten stuck where my code doesnt seem to be loading the internal clock correctly. I tried following this post as it seems very similar:

nrf54L15 LFRC 32KHz clock configuration issue - Nordic Q&A - Nordic DevZone - Nordic DevZone

but alas no. My program is currently hung up before entering main, somewhere in the clock setup. Heres the current trace:

Program received signal SIGTRAP, Trace/breakpoint trap.

Im fairly conviced the clock isnt connecting through as the syscounter doesnt seem to change (assuming i tracked it correctly)

ive been messing around with the prj.conf settings and am currently sitting at:

    status = "okay";

};

The code all built and ran before i added the clock stuff. I'm sure I'm missing something obvious her, software isn't my usual world. Let me know if theres more info i can add

This is the first time you mentioned using an Ublox NORA-B2 module. We cannot read your mind.

And yes, these modules should have the HFXO crystal included. Might want to check ublox documentation how to to configure the NCS SDK.

Oh shoot my bad! Didnt realize the NRF# wasnt the full info. I am using 

https://www.digikey.com/en/products/detail/u-blox/NORA-B206-00B/26163316?gclsrc=aw.ds&gad_source=1&gad_campaignid=120565755&gclid=CjwKCAiAssfLBhBDEiwAcLpwfqWPn3x-8agXqVeLRB9OhYzMLBUKvMwrghcGcHqGrwjzeeiikK6CWxoCMBgQAvD_BwE

which is the Ublox, i will check their docs!

It is working! There actually appear to be two issues which is what was slowing me down so much. The initial set up of the clocks was a problem, But also logging before something was ready was causing it to hang. This thread can be closed
