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
