nRF5340 Audio DK with the audio application nrf5340_audio - Testing Problem

PROBLEM:

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 on the Audio Example Page.

  • Now I'm trying to test the boards using the example in the Testing Section HERE.
  • The RGB2 and LED3 are not blinking as described. 
  • Can anyone help me to determine why?
  • Is the version of the SDK supported using the python script?
  • Did I build or program correctly?
  • I'm stuck. HAs anyone verified this SDK version with the Audio example ?
  • Do I need to use an earlier version of the SDK?

Development platform used:

  • Windows10
  • nRFConnect SDK version v2.4.0
  • Audio example from the directory C:\ncs\v2.4.0\nrf\applications\nrf5340_audio
  • Audio Example page nRF5340 Audio
  • Toolchain Manger v1.2.5

What I have done to this point:

  1. o To Build I use the command:
    1.  python buildprog.py -c both -b debug -d both -m external
    2. Results: the report showing a successful build
    3. Note: I'm using "-m external" because '-m internal" did not work because the debug firmware was too big, I mentioned this above.
  2. To Progra, I Use the command:
    1. python buildprog.py -c both -b debug -d both -p --recover_on_fail
    2. Results: the report showing that both the App and the net have been programmed to the boards.

    3. Still get the use recover arg error in the output, even though I ran the command with “--recover_on_fail” ?
      Received some other errors refer to “s4_program_sucess_with_recover.txt”
    4. NOTE: The App doc page is incorrect the program command has an incorrect argument “--recover-on-fail”! It should be defined with underscores not dashes.
      THIS NEEDS TO BE FIXED ON THE DOC PAGE TO STOP CONFUSION WHEN USING THE AUDIO EXAMPLE TO BUILD & PROGRAM the KIT

Here's a snapshot of the section on the Page where I'm referring to in my problem statement from above. Testing Section

  • Hi,

    Thank you very much for sharing your observations with us.

    • Now I'm trying to test the boards using the example in the Testing Section HERE.
    • The RGB2 and LED3 are not blinking as described. 
    • Can anyone help me to determine why?
    • Is the version of the SDK supported using the python script?
    • Did I build or program correctly?
    • I'm stuck. HAs anyone verified this SDK version with the Audio example ?
    • Do I need to use an earlier version of the SDK?

    Could you please specify how RGB2 and LED3 blink in your case compared to what is described in the documentation?

    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.  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.

    Still get the use recover arg error in the output, even though I ran the command with “--recover_on_fail” ?
    Received some other errors refer to “s4_program_sucess_with_recover.txt”

    Could you show the errors in the output that you refer to?

    NOTE: The App doc page is incorrect the program command has an incorrect argument “--recover-on-fail”! It should be defined with underscores not dashes.

    Yes, you are right. As you mentioned, a correct parameter would be --recover_on_fail. I have reported this internally and hope for a quick fix.

  • Hello  

    Thank you so much for responding so quickly. I will answer you questions about my problem.

    Could you please specify how RGB2 and LED3 blink in your case compared to what is described in the documentation?

    the 2 devices are plugged into the same USB connections on my PC running Windows 10. When I turn on the devices the LED's on both the gateway and the headset do not illuminate at all. There is no way for me to continue the test since it appears that "blinking green on every device to indicate the ongoing CPU activity"

    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.  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.

    The only reason to question the SDK is that I copied the audio example from the applications directory under the 2.4.0 release "C:\ncs\v2.4.0\nrf\applications\nrf5340_audio" to a new shorter named directory. I then ran the python script from there.I'd rather focus on this version of the SDK, to find out why the LEDS specified are not illuminated. 

    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.

    Yes, you are right. As you mentioned, a correct parameter would be --recover_on_fail. I have reported this internally and hope for a quick fix.

    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 "There is an ongoing process of restructuring the nRF5340 Audio application project.",.

    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.

    If anyone is interested you can follow my review blog on Element14 here Roadtest: Nordic Bluetooth LE Audio Development Kit nRF5340 DK. In this review myself and two other members have reviewed the Kit. I'm using this doc to try to get the 2 boards working with the Audio example. 

    Other Observations

    SOME KNOWN issues with different SDK versions and the Audio Application.

    i noticed in the TESTING section of the doc, there is a NOTE to check known issues related to serial connections. at nRF5340 Audio application known issues 

    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 Section report a issue with 2.4.0? 

    Also, here are the 6 com ports assigned when the devices are connected to the PC

    Shown here in my windows device manager. 

    Let me know your thoughts on this

  • Hi,

    Could you please show an error which you get when using "python buildprog.py -c both -b debug -d both -m internal" command for building the application?

    Best regards,
    Dejan

  • Hi,

    I used the -M in the command  "python buildprog.py -c both -b debug -d both -m internal -M" 

    I tried the build and program again and received no Error but the same results "NO LEDs are illuminated. I'll post the out at the end of this comment after I reply to your question.

    Could you please show an error which you get when using "python buildprog.py -c both -b debug -d both -m internal" command for building the application?

    I don't have a complete output but here are the notes I took. I hope you can see the error message on the screenshot.

    -----------------------------------------------------------------

    Now you're ready to run the script.

    1. Copy the sample example from the SDK version directory to C:\A\s1. I used v2.4.0, so here is the directory where the code is: C:\ncs\v2.4.0\nrf\applications\nrf5340_audio
    2. After this is copied, EDIT the Jason config file nrf5340_audio_dk_devices.json  as described 
    3. To build the script go to the directory    cd C:/A/s1/tools/buildprog
      1. python buildprog.py -c both -b debug -d both -m internal –M
      1. TURN on BOTH BOARDS
      2. Enter in the following command:
    4. it starts to build with the following output.

      But I ran into a fatal error with building zephyr FLASH OVERFLOW

      -------------------------------------------------------------------------------------------

       

      I tried the build and program again and received no Error but the same results "NO LEDs are illuminated.  here is the results

      BUilD and PROGRAM the Audio example
      $  python buildprog.py -c both -b debug -d both -m internal -M
      $ python buildprog.py -c both -b debug -d both -p --recover_on_fail

    1. hi again,

      I tried it again with a fresh directory and this time the build failed with the overflow error I mentioned.

      This is the output results from the long build. It shows where the overflow happens. it looks like the  problems with the flash using -internal -M

      skrug@DESKTOP-KJBLMH9 MINGW64 /c/A/s5/tools/buildprog
      $ python buildprog.py -c both -b debug -d both -m internal -M

    2. hi 

      I ended up getting things to working but the LEDs illumination does not coincide with the doc page?

      The LEDS are working an the boards and change colors to indicate the Gateway GREEN and Headset BLUE as shown.

      the doc page states:

      1. After programming, RGB2 starts blinking green on every device to indicate the ongoing CPU activity on the network core. LED3 starts blinking green on every device to indicate the ongoing CPU activity on the application core.

      2. Wait for the LED1 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.

      There are different for me

      • the RGB2 never blinks and is not Illuminated on both devices.?
      • LED3 is blinking YELLOW not green?
      • the LED1 is blinking BLUE on the gateway OK
      • But LED1 is ALSO blinking BLUE? IS THIS OK?

      QUESTIONS

      WHY is the RGB2 not illuminated?

      why is the LED3 blinking YELLOW not green? what is this indicating?

      ----------------------------------------------------------------------------------------------------------------------------------

      the following steps are what I did to get to this point:

      The bottom line is that since I only have 2 kits, the -m internal and the -M args should not be used. 

      To get it working I did the following:

      I rebooted my PC and started with a fresh directory

      changed the devices in the file nrf5340_audio_dk_devices.json 

      Build and Program using no -m internal -M on the build

      BUILD: python buildprog.py -c both -b debug -d both
      PROGRAM: python buildprog.py -c both -b debug -d both -p --recover_on_fail

      here is the full output

      sucessfull build
