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

The BMD-300 has read-back protection enabled from factory. Use this utility to do a full chip erase. After that you'll be able to program it.

Could you upload a picture of your connections? And explain how you have connected them.

Hi Peter,

The connection is as below,

BMD-300 -> nRF52-DK

SWDIO -> SH_SWDIO (pin #4) on P20

SWDCLK -> SH_SWDCLK (pin #5) on P20

VDD -> SH_VTG (pin #3) on P20

GND -> SH_GND_DETECT (pin #8) on P20

The BMD-300 is powered by VDD and GND pin from the nRF52 Development board.

The schematic is attached to the question.
