Hi,
I am have a custom breakout board that uses the NRF52832 chip and I was able to program it using the J-link programmer and seperating ribbon cable to expose the Vtarg, GND, SWDIO and SWDCLK lines.
Now I want to use the NRF52 Development kit for programming it using the p20 lines. I tried using NRFgo studio but the studio would not recognize an external device for programming.
I hooked it up so
Vtarg->3.3V output on voltage regulator on board
SWDIO->SWDIO on board
SWCLK->SWCLK on board
GNDdet->GND on board
I am powering it using an external battery connected to a voltage regulator.
Thank you
