RE: NRF9160 freezes after 2 days, watchdog not kicking in

Hi,

[quote user=""]Worth to mention that the NRF reset pin was pulled high to 3.3V by a 10kOhm, which was a schematic fault, and I removed the pull-ups. I have read other threads on devzone that clearly indicate that this is problematic but not sure if this mistake could really cause some damage leading to the observed behavior.[/quote]

No, this should not cause a problem after the pull up has been removed.

[quote user="Sebastiaan Merckx"]Maybe the ticket of https://devzone.nordicsemi.com/f/nordic-q-a/82388/nrf-connect-sdk-program-halt-after-a-few-days is related, I'll include that fix in the weekend runs.[/quote]

That was a good find.

In case it doesn't work, you can try to attach a debugger to see where the execution stops. Knowing what was the last thing to happen before it stopped is usually quite helpful.

Best regards,

Didrik
