power profiler, MAC pro, nrf51822 DK, Error while setting up device 000000123456: No firmware defined for selected device

I am using power profiler from my MAC pro, to test my 51822 DK. And I got following errors: 

Error while setting up device 000000123456: No firmware defined for selected device

The NRF Connect version is 3.3

You need an nRF52DK as the debugger on the nRF51DK can't interface with the nRF52 on the PPK. You can power and measure the nRF51DK via the PPK's EXT output.
