Hi,

I think you are running into a issue that is fixed in the latest release.

See this commit:

https://github.com/nrfconnect/sdk-zephyr/commit/df1125a58c8a313b6518ef44054d6c25f37e15a4

There are also some other bugs in task_wdt that is fixed in the latest release.

test-devzone.nordicsemi.com/.../78206.main.c

test-devzone.nordicsemi.com/.../4338.prj.conf

So here are the two files - In my main, I initialize WDT at bootup and start it and then there is the connect() do_while loop, which takes roughly 10 seconds to complete so I want my wdt to fire and reboot just for testing, but instead it just hangs indefinitely.

And yes, the example worked for me. Not sure what I'm missing here.

Hi,

[quote user=""]Based on the example, I initialize the WDT and add a sleep > watchdog time after a count of 50, but instead of calling a wdt callback or system reset, my code just gets stuck into an undefined state. [/quote]

I tried reproducing this, but it's working fine here. Could you post your whole main.c and prj.conf?

Does the unmodified sample work as expected? What board target did you build for?
