I do NOT need to reprogram any bootloader - all I need to do is get my own code onto the nRF52832 Breakout, via the nRF52-DK.
The reason I am trying to use the nRF52-DK is because programming ONE sketch to the breakout via Arduino the first time I used it, caused the bootloader to die.
I've also tried using Beef圓 FTDI to power the target, eliminating the nRFVDD connection. I've re-checked all connections and voltages. However, though several people claim this is the "correct" configuration, and simply telling Segger Studio to download code to target will Automatically detect the external target via the P20 connections (as above, plus SWDIO -> D, SWDCLK -> C, RESET -> RESET, on the breakout), the only thing that appears to be "programmed" is the DK board, NOT the breakout board. This appears to be an ADVANTAGE in that the voltages on DK and Target will be identical (a given requirement). It appears to me that the following connections serve to POWER THE TARGET from the DK board, so that you don't need to power the target separately. One of the conflicting comments I've seen concerns the use of "nRF VDD" being tied to "VTG" some say it's needed, some say it's not. I've found conflicting information, and reached some conclusions, but still cannot program the Sparkfun nRF52832 breakout, using the Nordic '52 DK board. I've read all the posts I can find on Nordic forum, here, and everywhere re: nRF52832 programming.
