I haven&#39;t found this stated anywhere explicitly. If not, is thereen-USTelligent Community 13Thu, 27 Apr 2017 06:45:20 GMThttps://devzone.nordicsemi.com/thread/85155?ContentTypeID=1Thu, 27 Apr 2017 06:45:20 GMT137ad170-7792-4731-bb38-c0d22fbe4515:93770b6c-b00a-4839-8c56-564b20906eb9RK<p>No it&#39;s not possible to do anything on a fresh chip until it has had some software put on it via SWD. It&#39;s asked quite often here in relation to production programming.</p> <p>You can do any old steps in any old order you like. As long as you have the thing connected to a Segger or similar you just put on it what you put on it for development. The Segger basically blows the whole chip away with an erase so it&#39;s the same thing.</p><div style="clear:both;"></div>
