Hi all I followed the instructions on how to setup newt tool and then blinky on the nrf52 DK.

This isn't reflected in the docs (and I don't think it should be). Is there something amiss with the newt tool ? I was able to build and load by following the other instructions to the T. PS: new to the project, looks cool ! Looking forward to contribute ! Cheers, Anuj
