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.

Hi Wojtek,

Are you sure the external device is programmed without connecting VDD_REF with VDD and GND pins(not GNDDetect)?

Because When I follow the connection you mentioned only the internal MCU is being programmed!! When I connect VDD and sending the recover command,I am getting the same error!

thanks
