 I cannot load the Radio Test code onto the Nordic NRF52 devkit. I&amp;#39;m using SDK15.3 and the project located at C:\nRF5_SDK_15.3.0\examples\peripheral\radio_test. 
 The program compiles but I receive the error &amp;quot;Error: Flash Download Failed. - Cortex</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Mon, 12 Aug 2019 18:10:05 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/50814/radio-test" /><item><title>RE: Radio Test</title><link>https://devzone.nordicsemi.com/thread/203680?ContentTypeID=1</link><pubDate>Mon, 12 Aug 2019 18:10:05 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:d028fca7-ce68-4aa1-ab0a-f1a99d855dff</guid><dc:creator>Gerber</dc:creator><description>&lt;p&gt;Got it working.&amp;nbsp; Thanks.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Radio Test</title><link>https://devzone.nordicsemi.com/thread/203660?ContentTypeID=1</link><pubDate>Mon, 12 Aug 2019 15:28:27 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:0e53dc62-9ff1-4070-b71f-c33e5c2dca26</guid><dc:creator>Hung Bui</dc:creator><description>&lt;p&gt;Hi,&lt;/p&gt;
&lt;p&gt;It should be quite straight forward. For example to do a modulated carrier at frequency 2440MHz you do this:&amp;nbsp;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;&lt;strong&gt;start_channel 40&lt;/strong&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;&lt;strong&gt;start_tx_modulated_carrier&amp;nbsp;&lt;/strong&gt;&lt;/span&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Radio Test</title><link>https://devzone.nordicsemi.com/thread/203648?ContentTypeID=1</link><pubDate>Mon, 12 Aug 2019 14:43:48 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:9629e39b-6005-4157-a75b-1d7b0944bea4</guid><dc:creator>Gerber</dc:creator><description>&lt;p&gt;Hell Hung Bui&lt;/p&gt;
&lt;p&gt;I programmed my boards using Segger.&amp;nbsp; Originally, I was using Keil.&amp;nbsp; I&amp;#39;m not sure why this is the case. &amp;nbsp;&lt;/p&gt;
&lt;p&gt;Now that the boards are working with the radio test example, if I try to initialize a start channel and then begin transmission, I cannot detect anything on the receiving board.&amp;nbsp; Is there a step by step procedure for transmitting a pattern and then receiving it?&lt;/p&gt;
&lt;p&gt;thanks&lt;/p&gt;

&lt;p&gt;Maybe you need to do an eraseall on the chip (nrfjprog --eraseall) . If the softdevice already on the chip you wouldn&amp;#39;t be able to flash the radio_test example.&amp;nbsp;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
