 It seems that I only need 4 pins for the Segger J-Link Base (VTREF/SWDIO/SWDCLK/GND), correct?

&lt;li&gt;yes , the &lt;a href="http://embeddedsoftdev.blogspot.ca/p/idap-link.html"&gt;IDAP-Link&lt;/a&gt; has full support for parallel programming of nRF5x series include capability of flashing softdevice and DFU without mergehex.&lt;/li&gt;

&lt;ol&gt;
&lt;li&gt;
&lt;p&gt;Yes, correct.&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;No, you don&amp;#39;t need RESET pin to program/debug. You can do softreset if you don&amp;#39;t have access to the RESET pin. RESET pin is optional on nRF52, you can actually disable RESET and use the pin as normal GPIO pin.&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;I think it&amp;#39;s fine, as long as it connects the correct pins.&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;I actually don&amp;#39;t know. Maybe someone here knows. Have you checked on Segger website ?&lt;/p&gt;
&lt;/li&gt;
