Thanks for the help, I ended up finding that the momentary ON button was not being depressed during programming; I was under the impression originally that the unit provided power on its own but found differently. Thanks for the responses and attention on this!

You should be able to use the Segger tools to report what voltage it is seeing from the Target.

Segger have a page on diagnosing J-Link problems:

Hi,

Exactly what error are you getting?
Are you using a custom board? If so, could you provide the schematics and layout?
Could see if your device is listed if you enter this nrfjprog command:

nrfjprog --ids
