I don't think it's been solved. I would suggest to use it as external DUT.
But anyway when you run the DK in debug mode, the current consumption will be high as the CPU and debugger interface is on all the time, regardless the code.

Hi,

Is this fixed? Just got a PPK yesterday. It stops running as soon as I launch the nRF DK debug session.

Configuration: PPK plugged into PCA10040. Segger J-Link connected to PPK P21 Development firmware on PCA10040 uses RTT, but is a separate serial number from Segger J-Link, so should not be a problem.

Thank you.

Hi,

I tried here and confirm that there is an issue connecting to the PPK after setting the DK into debug mode. I have reported the issue to the developer. I would suggest to use the external DUT port for measuring power consumption on the DK separately instead.
