External programming Using nRF52-DK

Hello

I have a nRF52-DK and I am trying to programme an external designed by myself but this one contains the nRF51422 chip. I am using nRFGO Studio to upload the .HEX file.

Do you know if it is possible even with different chips?

I am following these connections between my board and nRF52-DK.

My Board(nRF51422) -> nRF52-DK

SWDIO -> SH_SWDIO (pin #4) on P20

SWDCLK -> SH_SWDCLK (pin #5) on P20

VDD -> SH_VTG (pin #3) on P20 and VDD (pin #1)

GND -> SH_GND_DETECT (pin #8) on P20 and GND

  • It is possible. I am using P19 on nRF52-DK, and i just connect 4 lines from it: VCC(pin1), SWDIO(pin2), GND(pin3), SWDCLK(pin4 and wire them to corresponding pins on nRF51 chip. I am programming/debugging without problems that way.

    External (nRF51) chip has to be powered to be detected by programmer that way (if not, nRF52-DK onboard nrf52832 will be detected only).
