rigado BMD-300 with nRF52 DK

[Vishnu Pradeep]

HI, Can anybody give me the connections to a BMD-300 with nRF52DK and the steps to program a BMD-300 from scratch? Which document provides the information, if there is any?

thanks, Vishnu

I am really sorry, but i have mislead you!

I am using 4 wires! Pin 1,2,4 and 5 on this picture. i forgot about Vtref

I have been using SWDap recently, and it did not need VTref pin, only SWDIO, SWCLK and GND. But Jlink does also need vtref
