Not able to program BMD-350-A-R by using SWD Pins of Nrf52Dk

[Ali_Malik]

Hi!

I have BMD-350 -A-R and I want to program this by using SWD pins (SWCLK, SWDIO, GND Detect, and VTG) of Nrf52Dk. I make all the connections properly but for some reason, I am not able to program the external chip and no error appears. Whenever I compile, the onboard chip Nrf52832 programs by using J-link and worked fine. Please let me know what is the possible solution for this problem and how I can load my program within BMD-350-A-R step by step?

Hi,

Have you remembered to either add the necessary low frequency external clock source or switched the LFCLK clock source in your project to the RC oscillator or the synthesized one?
