Programming custom board

[SentinelLighting]

Having problems with nrfjprog and a custom board.  I connected my custom board to the NDK via P20 and flashed a program to it.  The program was a variant of the pwm_library.  The initial flash reported ok but program did not seem to work correctly so made some changes I flashed it again.  The second (and any subsequent) attempts all return an error.  Here is my erase sequence and the responses:
nrfjprog -f NRF52 -e. 
Response: ERROR: JLinkARM DLL reported an error.  Try again.  If error condition persists, run the same command with argument --log. 
I did here is the log:

This appears to be a problem with my cabling that connects between the SDK and my board.  I shortened the wires and did a direct connect (as shown in other Devzone articles) and I can talk to my board.  The difference is I was originally trying to be a) "self" powered, I connected my onboard VCC to VTG and did not use the VDD on the SDK. b)  I went from the SDK to an "test" PCB then went from the test PCB using the Tag Connect cable harness to go to my target PCB.  The wires ohm out as correct, but the SDK doesn't seem to be able to talk thru all the wires/intermediate board to program my  target. 
Questions:

1) Do you have to be powered by the SDK

2) Are there wiring/distance limitations

Any help would be great!

If your board is powered with ~2.8V-3.3V, it should work.  Other voltage might not.  I don't think the DK has level shifter to allow you to flash custom board with different voltage.  As a low cost alternative, you can use the IDAP-Link CMSIS-DAP debug JTag.  Fully support nRF5x serie including flashing Softdevice & DFU without having to use mergerhex.

Hi Brian, 

when using a nRF52 DK to program an external board, you need to connect the VTG pin on the P20 Header to a pin that is ~2.8V-3.3V. Otherwise, the J-Link OB will program the nRF52 chip on the DK. In orther words, the VTG pin is only a voltage sensing pin that decides which nRF52 that should be flashed, the onboard one or the external one.  If you want to power you external board, then connect VDD on the P20 header to VCC on your external board. 

Have not run into any issues with regular Dupont/jumper wires.
