 I have nRF52833 and nRF9160 on my custom board. Due to limited space available, trying to use a common SWD interface between the two SoCs. As follows: 1) SWDIO and SWDCK from each SoC connected together and out to debug/ programming header; 2) Reset</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Wed, 11 Nov 2020 08:28:36 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/68220/sharing-swd-lines-between-nrf52-and-nrf91" /><item><title>RE: Sharing SWD lines between nRF52 and nRF91</title><link>https://devzone.nordicsemi.com/thread/279417?ContentTypeID=1</link><pubDate>Wed, 11 Nov 2020 08:28:36 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:b38da074-01f3-4e3e-bc09-9f447b10b4b9</guid><dc:creator>ketiljo</dc:creator><description>&lt;p&gt;This is not recommended and all sorts of problem may happen. Given that you can share VDD and GND, you need 6 pins for the two devices with separate SWD lines, and 6 pins with shared SWD and a reset line for each. So you don&amp;#39;t save any pins this way.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;Reset is not needed for the debugger/programmer.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
