How to configure NRF51-DK to flash firmware to a different nrf51 module

[Denver]

Hi all, I have here NRF51-DK, I am a bit familiar with the kit for a while. Now I want to make a system using NRF518422 chip. I manage to find a module - "Taiyo Yuden EYAGJNZXX".

My question is, Is there a way to make use of my NRF51-DK to flash application and softdevice to EYAGJNZXX?

Thank you very much.

If you search this forum there are literally dozens of similar questions which were answered. You need to connect it through P19 or P20 headers (JTAG/SWD OUT ports), see Dev Kit's user guide how to locate them. The magic is in wiring correctly also Voltage and Ground detect PINs so J-Link OB FW on the Dev Kit will detect external target on one of these ports and don't try to flash internal nRF5x chip on the Dev Kit.

Hi thank you for that. Actually I already manage to locate the pins. I was kind of worried that there might be some setup that I am missing. :)

I usually use P20 with some speed wires, providing 3V3 from nRF5x DK and then properly grounding whole system + the final trick of connecting VTG detect with 3V3 (shorting PINs 2 and 3 on P20) makes the job for me basically always...
