It seems that the issue was with the power supply I was using to feed the host device. I changed my power supply to the PPKII and now the sample works. So this ticket can be closed

Thank you very much for you testing the sample.

This is a log from my side:

As you can see on my log the device resets after the second scan.

Currently I have not made any changes to the shutdown sample.

The only thing that I have done on my board is following the instructions for the dual PPK current measurement setup is to cut SB 16 and connect SB 17.

Could you perhaps share with me the hex file you have produced so that I can put it on my device and see what happens?

Can you please share a log of the issue that you are observing, and if any changes to the sample; post those as well?

Kind regards,
