Hello JONATHAN LL,

We have update the SDK to 2.4.0 and added the Watchdog as the firmware must be ready for production now.

You can close this ticket as we do not observe any problem with current implementation.

Best regards,

Simon

Sorry for the slow response time here, but lets try and dig a little deeper.

I cant determine anything from the information provided yet, but I do have some extra questions that might get us further.

So,

- In the image that you share the environment NCS v2.2.0 is shown, does that match the project or are you on a newer version.

- Can you show the register values when you are in the error handler. The IPSR (xPSR) register will show if the program is in an interrupt context or not.

Regards,
Jonathan

Hello Jonathan,

Yes that' my problem: it is hard to reproduce. When I have 20 boards alive, one has the problem after few days/hours, maybe another 2 days later, etc. That's quite random (at least at first look).

I will provide the error when trying to debug.

I have a GPIO that changed the LED state through an interruption and this works. I have other GPIO's or LED's that can be used. What should I look at?

Any idea of how to spot the problem is welcome!

Regards,

Simon

Not much to work on with just the description, can you provide the output error when trying to debug? or do you have some other GPIO's or LED's that could be used for debugging?

Can you reproduce the issue on a development kit?

Jonathan
