Yes,the fact that it worked at all - but for a while was a bit perplexing.

I'm still not sure how this could cause the program to suddenly stop operating after several minutes. Anyway. Thank you for the update, I'm glad to hear that it works now.

This solved the issue.... I thought the LF clock had something to do with it, but couldn't find what to look for... Thanks....

Using RC or synth as LF clock source worked like a charm.

Correction: You probably won't find the CLOCK_CONFIG_LF_CAL_ENABLED setting in your project as it seems to have been introduced in a later SDK version (I was looking at the example in SDK 17.0.2)

Currently I have not changed anything from the PCA10056 (building from the same directory) setup. Will have a look at those two configs.

If problem persists I will have a look at the registers

Hello,

I can't think of any obvious reasons for this. I assume you changed the CLOCK_CONFIG_LF_SRC and CLOCK_CONFIG_LF_CAL_ENABLED to use the internal RC oscillator?

When the device stops blinking, could you attach the debugger and read the CPU registers to try determine what state the device is in (if it's stuck in a fault handler, etc)?

Reading CPU registers from running target using nrfjprog:

nrfjprog --readregs

Forgot to mention. Our code base currently is using SDK 15.
