We have a number of fixtures using nRF52 DK boards to both flash a custom board and to do a DFU operation to that board. We use a SPST switch in the P19 pin 1 lead in the Tag-connect cable to switch. These working fixtures use a DK version 2.1.0. New builds have a version 3.0.3 DK board which seems not to listen to the state of P19 pin 1. What is the problem.
