Hi,

The link you sent is for a commit that, I believe, was merged in the NCS v3.1.0. So to see if it fixes your issue you can either try to patch your current SDK or try to migrate to a later version.

Also, you can check the "known Issues" page. It looks like NCSDK-31528 or NCSDK-30959 can be relevant. Did you already try the proposed workarounds ?

If the workarounds don't work, can you please share a bit more (code snippet, debug logs, ...)

Best regards,

Simon D-M

I put a breakpoint in the WDT Kick area. Though it could be that most of the device is 'sleeping' / WFI as such a 5s WDT timeout might take 100's of seconds before it times out.

Some of the deadlocks won't keep any thread in running state, i.e. all threads are in one of the waiting functions similar to k_sem_take().

Thus its highly likely that your WDT thread was still able to run even if its at lowest priority. How do you know it did not refresh WDT?
