 I am trying to test the nRF5340 Audio DK with the audio application nrf5340_audio. This application is included with the version of the SDK under the applications folder. I have successfully built and programed two boards following the directions</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Wed, 28 Jun 2023 21:00:42 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/101195/nrf5340-audio-dk-with-the-audio-application-nrf5340_audio---testing-problem" /><item><title>RE: nRF5340 Audio DK with the audio application nrf5340_audio - Testing Problem</title><link>https://devzone.nordicsemi.com/thread/433551?ContentTypeID=1</link><pubDate>Wed, 28 Jun 2023 21:00:42 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:87315cdc-b6eb-42a0-8a9e-eb575ea984f6</guid><dc:creator>SteveKay</dc:creator><description>&lt;p&gt;I have marked this as the solution:&lt;/p&gt;
&lt;p&gt;With the help of&amp;nbsp;&lt;a href="https://devzone.nordicsemi.com/members/dejans"&gt;dejans,&lt;/a&gt;I was able to come to the following Build and Program arguments to the pyton script to get it to a point where the 2 audio kits were programmed properly with the&amp;nbsp;Audio Example.&lt;/p&gt;
&lt;p&gt;Here are the steps I took:&lt;/p&gt;
&lt;ol&gt;
&lt;li&gt;I rebooted my PC and started with a fresh directory&lt;/li&gt;
&lt;li&gt;changed the devices in the file&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;strong&gt;nrf5340_audio_dk_devices.json&amp;nbsp;&lt;/strong&gt;&lt;/li&gt;
&lt;li&gt;Build and Program using no -m internal -M on the build
&lt;ol&gt;
&lt;li&gt;BUILD: python buildprog.py -c both -b debug -d both&lt;/li&gt;
&lt;li&gt;PROGRAM: python buildprog.py -c both -b debug -d both -p --recover_on_fail&lt;/li&gt;
&lt;/ol&gt;
&lt;/li&gt;
&lt;/ol&gt;
&lt;p&gt;Here is the command screen showing the results of the 2 commands.&lt;/p&gt;

The issue happens due to debug version being too large. The solution for this is to use the release version.[/quote]
&lt;p&gt;Thanks for taking the time to reproduce the problem. Just as I had thought debug was too large.&lt;/p&gt;
&lt;p&gt;At one point in trying to Build and Program,&amp;nbsp;&lt;span style="font-family:inherit;"&gt;I did try the -release arg for both&amp;nbsp; commands, but I had errors so I abandoned it. I never was able to get it working.&lt;/span&gt;&lt;/p&gt;
[quote userid="111786" url="~/f/nordic-q-a/101195/nrf5340-audio-dk-with-the-audio-application-nrf5340_audio---testing-problem/433414"]I agree with you that subjectively colors are not quite green, but more on the yellow side. However, the actual color defined by the manufacturer is green. &lt;br /&gt;Regarding RGB2 not blinking, we are aware of this issue, and it does not affect anything[/quote]
&lt;p&gt;The trouble is that YELLOW in the USA indicates CAUTION. GREEN means GO and RED means STOP. &amp;#39;&amp;#39;&amp;#39;LOL...&lt;/p&gt;
&lt;p&gt;So the blinking YELLOW light to me, means that something is wrong. GREEN would make more sense as an indicator. But no need to split hairs here, It&amp;#39;s working now and I can move on to testing the application according to the audio app doc page.&lt;/p&gt;
&lt;p&gt;&lt;span style="text-decoration:underline;"&gt;&lt;strong&gt;ONE more question?? for you..&lt;/strong&gt;&lt;/span&gt;.&lt;/p&gt;
&lt;p&gt;Although now, that I&amp;nbsp; have a successful build &amp;amp; program&amp;nbsp;&lt;/p&gt;
&lt;p&gt;I still get an error in the recover section of the PROGRAM run. I included the segment from the command screen below.&lt;/p&gt;
&lt;p&gt;As you can see it is trying to recover and tells me that I need to use the recover arg, which I did use.? So that&amp;#39;s a bit confusing?&amp;nbsp; And then it tells me that there is an error recovering the left headset?&amp;nbsp; Just interested if you know what this is? ERROR means that something has gone wrong.. I think it should be [INFO]&lt;/p&gt;

The issue happens due to debug version being too large. The solution for this is to use the release version.&lt;br /&gt;&lt;pre class="ui-code" data-mode="text"&gt;python buildprog.py -c both -b release -d both -m internal&lt;/pre&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;I agree with you that subjectively colors are not quite green, but more on the yellow side. However, the actual color defined by the manufacturer is green. &lt;br /&gt;Regarding RGB2 not blinking, we are aware of this issue, and it does not affect anything.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;Best regards,&lt;br /&gt;Dejan&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: nRF5340 Audio DK with the audio application nrf5340_audio - Testing Problem</title><link>https://devzone.nordicsemi.com/thread/433351?ContentTypeID=1</link><pubDate>Wed, 28 Jun 2023 05:17:50 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:ba77b6ed-7375-4ee9-976d-6f7ce7967be7</guid><dc:creator>SteveKay</dc:creator><description>&lt;p&gt;hi&amp;nbsp;&lt;/p&gt;
&lt;p&gt;I ended up getting things to working but the LEDs illumination does not coincide with the doc page?&lt;/p&gt;
&lt;p&gt;The LEDS are working an the boards and change colors to indicate the Gateway GREEN and Headset BLUE as shown.&lt;/p&gt;
&lt;p&gt;&lt;img style="max-height:126px;max-width:126px;" alt=" " height="126" src="https://devzone.nordicsemi.com/resized-image/__size/252x252/__key/communityserver-discussions-components-files/4/pastedimage1687929389285v3.png" width="126" /&gt;&lt;/p&gt;
&lt;p&gt;the doc page states:&lt;/p&gt;
&lt;ol class="arabic"&gt;
&lt;li&gt;
&lt;p&gt;After programming,&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;strong&gt;RGB2&lt;/strong&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;starts blinking green on every device to indicate the ongoing CPU activity on the network core.&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;strong&gt;LED3&lt;/strong&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;starts blinking green on every device to indicate the ongoing CPU activity on the application core.&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;Wait for the&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;strong&gt;LED1&lt;/strong&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;on the gateway to start blinking blue. This happens shortly after programming the development kit and indicates that the gateway device is connected to at least one headset and ready to send data.&lt;/p&gt;
&lt;/li&gt;
&lt;/ol&gt;
&lt;p&gt;&lt;span style="font-size:75%;"&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="font-size:inherit;"&gt;There are different for me &lt;/span&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style="font-size:inherit;"&gt;the RGB2 never blinks and is not Illuminated on both devices.?&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style="font-size:inherit;"&gt;LED3 is blinking YELLOW not green?&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style="font-size:inherit;"&gt;the LED1 is blinking BLUE on the gateway OK&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style="font-size:inherit;"&gt;But LED1 is ALSO blinking BLUE? IS THIS OK?&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;QUESTIONS&lt;/p&gt;
&lt;p&gt;WHY is the RGB2 not illuminated?&lt;/p&gt;
&lt;p&gt;&lt;span style="font-size:inherit;"&gt;why is the LED3 blinking YELLOW not green? what is this indicating?&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="font-size:inherit;"&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;----------------------------------------------------------------------------------------------------------------------------------&lt;/p&gt;
&lt;p&gt;the following steps are what I did to get to this point:&lt;/p&gt;
&lt;p&gt;The bottom line is that since I only have 2 kits, the -m internal and the -M args should not be used.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;To get it working I did the following:&lt;/p&gt;
&lt;p&gt;I rebooted my PC and started with a fresh directory&lt;/p&gt;
&lt;p&gt;changed the devices in the file &lt;strong&gt;nrf5340_audio_dk_devices.json&amp;nbsp;&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;Build and Program using no -m internal -M on the build&lt;/p&gt;
&lt;p&gt;BUILD: python buildprog.py -c both -b debug -d both &lt;br /&gt;PROGRAM: python buildprog.py -c both -b debug -d both -p --recover_on_fail&lt;/p&gt;
&lt;p&gt;here is the full output&lt;/p&gt;

&lt;p&gt;I tried it again with a fresh directory and this time the build failed with the&amp;nbsp;overflow error I mentioned.&lt;/p&gt;
&lt;p&gt;This is the output results from the long build. It shows where the overflow happens. it looks like the&amp;nbsp; problems with the flash using -internal -M&lt;/p&gt;

&lt;p&gt;I don&amp;#39;t have a complete output but here are the notes I took. I hope you can see the error message on the screenshot.&lt;/p&gt;
&lt;p&gt;-----------------------------------------------------------------&lt;/p&gt;
&lt;h4 id="title19"&gt;&lt;b&gt;&lt;i&gt;Now you&amp;#39;re ready to run the script.&lt;/i&gt;&lt;/b&gt;&lt;/h4&gt;
&lt;ol&gt;
&lt;li&gt;&lt;span&gt;Copy the sample example from the SDK version directory to&amp;nbsp;&lt;/span&gt;&lt;span&gt;C:\A\s1&lt;/span&gt;&lt;span&gt;. I used v2.4.0, so here is the directory where the code is: C:\ncs\v2.4.0\nrf\applications\nrf5340_audio&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;After this is copied, EDIT the Jason config file&amp;nbsp;&lt;/span&gt;&lt;span&gt;nrf5340_audio_dk_devices.json&lt;/span&gt;&lt;span&gt;&amp;nbsp; as&amp;nbsp;&lt;/span&gt;&lt;span&gt;described&amp;nbsp;&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;To build the script go to the directory&amp;nbsp; &amp;nbsp; cd C:/A/s1/tools/buildprog&lt;/span&gt;
&lt;ol&gt;
&lt;li&gt;&lt;span&gt;python buildprog.py -c both -b debug -d both -m internal &amp;ndash;M&lt;/span&gt;&lt;/li&gt;
&lt;/ol&gt;
&lt;ol&gt;
&lt;li&gt;&lt;span&gt;TURN on BOTH BOARDS&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span&gt;Enter in the following command:&lt;/span&gt;&lt;/li&gt;
&lt;/ol&gt;
&lt;/li&gt;
&lt;li&gt;&lt;span&gt;it starts to build with the following output.&lt;/span&gt;&lt;/li&gt;

&lt;p&gt;the 2 devices are plugged into the same USB connections on my PC running Windows 10. When I turn on the devices the LED&amp;#39;s on both the gateway and the headset&amp;nbsp;&lt;strong&gt;do not illuminate at all&lt;/strong&gt;. There is no way for me to continue the test since it appears that &amp;quot;&lt;span&gt;blinking green on every device to indicate the ongoing CPU activity&lt;/span&gt;&amp;quot;&lt;/p&gt;

Looking at your provided outputs, I would assume that you programmed the devices correctly and they should work as expected.&amp;nbsp; In addition, there does not seem to be the case that there is something wrong with the SDK. You can always try previous version in case you want to verify programming procedure, compare the outputs or check the colors of RGB2 and LED3.[/quote]
&lt;p&gt;The only reason to question the SDK is that I copied the audio example from the applications directory under the 2.4.0 release &amp;quot;C:\ncs\v2.4.0\nrf\applications\nrf5340_audio&amp;quot; to a new shorter named directory. I then ran the python script from there.I&amp;#39;d rather focus on this version of the SDK, to find out why the LEDS specified are not illuminated.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;I would normally debug the application, but I use VSCode to debug C code and VSCode is not supported. So I seek advice from DevZone.&lt;/p&gt;

As you mentioned,&amp;nbsp;a correct parameter would be --recover_on_fail. I have reported this internally and hope for a quick fix.[/quote]
&lt;p&gt;Thanks for reporting this. Is there a way for uses to be aware of Nordic documentation updates? Other vendors, like Renesas support send email notifications to document updates that the user is interested in.. I realize and the doc page notes specifies right up front, that this is experimental and that &amp;quot;&lt;span&gt;There is an ongoing process of restructuring the nRF5340 Audio application project.&lt;/span&gt;&amp;quot;,.&lt;/p&gt;
&lt;p&gt;It would be nice to know for makers like myself who are experimenting with the example and trying to get the application running before making experimental changes.&lt;/p&gt;
&lt;p&gt;If anyone is interested you can follow my review blog on Element14 here &lt;a href="https://community.element14.com/products/roadtest/rv/roadtest_reviews/1678/roadtest_nordic_bluetooth_le_audio_development_kit_nrf5340_dk_by_steve_k" rel="noopener noreferrer" target="_blank"&gt;Roadtest: Nordic Bluetooth LE Audio Development Kit nRF5340 DK&lt;/a&gt;. In this review myself and two other members have reviewed the Kit. I&amp;#39;m using this doc to try to get the 2 boards working with the Audio example.&amp;nbsp;&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Other Observations&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;SOME KNOWN issues with different SDK versions and the Audio Application.&lt;img class="align-right" style="float:right;max-height:153px;max-width:328px;" alt=" " height="153" src="https://devzone.nordicsemi.com/resized-image/__size/656x306/__key/communityserver-discussions-components-files/4/pastedimage1687798566649v7.png" width="328" /&gt;&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;i noticed in the TESTING section of the doc, there is a NOTE to check known issues related to serial connections. at&amp;nbsp;&lt;a class="reference internal" href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/known_issues.html#known-issues-nrf5340audio"&gt;&lt;span class="std std-ref"&gt;nRF5340 Audio application known issues&lt;/span&gt;&lt;/a&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;As noted there are Detection issues with USB-C to USB-C connections, but my PC does not have USB-C connectors. So, I was wondering if it also affect my USB PC USB connection also? Also the versions affected include SDK version 2.4.0. How can I dig deeper into the release notes if possible? All issues listed in the known issues page under the nRF5340 Audio&amp;nbsp;Section report a issue with 2.4.0?&amp;nbsp;&lt;/p&gt;
&lt;h3 id="mcetoc_1h3sblv430"&gt;Also, here are the 6 com ports assigned when the devices are connected to the PC&lt;/h3&gt;
&lt;p&gt;Shown here in my windows device manager.&amp;nbsp;&lt;/p&gt;

&lt;p&gt;Let me know your thoughts on this&lt;/p&gt;
&lt;p&gt;Regards&lt;/p&gt;

[quote user=""]&lt;ul&gt;&lt;li&gt;&lt;span&gt;Now I&amp;#39;m trying to test the boards&amp;nbsp;using&amp;nbsp;the example in the &lt;/span&gt;&lt;a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/applications/nrf5340_audio/README.html#testing"&gt;Testing Section HERE&lt;/a&gt;.&lt;/li&gt;
&lt;li&gt;The RGB2 and LED3 are not blinking as described.&amp;nbsp;&lt;/li&gt;
&lt;li&gt;Can anyone help me to determine why?&lt;/li&gt;
&lt;li&gt;Is the version of the SDK supported using the python script?&lt;/li&gt;
&lt;li&gt;Did I build or program correctly?&lt;/li&gt;
&lt;li&gt;I&amp;#39;m stuck. HAs anyone verified this SDK version with the Audio example ?&lt;/li&gt;
&lt;li&gt;Do I need to use an earlier version of the SDK?&lt;/li&gt;&lt;/ul&gt;[/quote]
&lt;p&gt;Could you please specify how RGB2 and LED3 blink in your case compared to what is described in the documentation?&lt;br /&gt;&lt;br /&gt;Even if you see different colors than expected, there might still be no problem with how the sample is built or programmed. Looking at your provided outputs, I would assume that you programmed the devices correctly and they should work as expected.&amp;nbsp; In addition, there does not seem to be the case that there is something wrong with the SDK. You can always try previous version in case you want to verify programming procedure, compare the outputs or check the colors of RGB2 and LED3.&lt;br /&gt;&lt;br /&gt;&lt;/p&gt;
[quote user=""]Still get the use recover arg error in the output, even though I ran the command with “--recover_on_fail” ?&lt;br /&gt;Received some other errors refer to “s4_program_sucess_with_recover.txt”[/quote]
&lt;p&gt;Could you show the errors in the output that you refer to?&lt;/p&gt;
[quote user=""]NOTE:&amp;nbsp;The App doc page is incorrect the program command has an incorrect argument “--recover-on-fail”! It should be defined with underscores not dashes.&lt;br /&gt;THIS NEEDS TO BE FIXED ON THE DOC PAGE TO STOP CONFUSION WHEN USING THE AUDIO EXAMPLE TO BUILD &amp;amp; PROGRAM the KIT[/quote]
&lt;p&gt;Yes, you are right. As you mentioned,&amp;nbsp;a correct parameter would be --recover_on_fail. I have reported this internally and hope for a quick fix.&lt;br /&gt;&lt;br /&gt;Best regards,&lt;br /&gt;Dejan&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
