nRF5340 Audio DK with the audio application nrf5340_audio - Testing Problem

[SteveKay]

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. 
   4. 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

[SteveKay]

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

Hi,

I have reproduced your reported problem with flash overflow. The issue happens due to debug version being too large. The solution for this is to use the release version.

python buildprog.py -c both -b release -d both -m internal

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.
Regarding RGB2 not blinking, we are aware of this issue, and it does not affect anything. 

Best regards,
Dejan

Thanks for taking the time to reproduce the problem. Just as I had thought debug was too large.

At one point in trying to Build and Program, I did try the -release arg for both  commands, but I had errors so I abandoned it. I never was able to get it working.

The trouble is that YELLOW in the USA indicates CAUTION. GREEN means GO and RED means STOP. '''LOL...

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's working now and I can move on to testing the application according to the audio app doc page.

ONE more question?? for you...

Although now, that I  have a successful build & program 

I still get an error in the recover section of the PROGRAM run. I included the segment from the command screen below.

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's a bit confusing?  And then it tells me that there is an error recovering the left headset?  Just interested if you know what this is? ERROR means that something has gone wrong.. I think it should be [INFO]

I have marked this as the solution:

With the help of dejans,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 Audio Example.

Here are the steps I took:

1. I rebooted my PC and started with a fresh directory
2. changed the devices in the file nrf5340_audio_dk_devices.json 
3. Build and Program using no -m internal -M on the build
   1. BUILD: python buildprog.py -c both -b debug -d both
   2. PROGRAM: python buildprog.py -c both -b debug -d both -p --recover_on_fail

Here is the command screen showing the results of the 2 commands.

I am evaluating two nRF5340 audio DK's. I am using one as a Gateway and the other as a Left Headset. I was only supplied with 2 kits to evaluate. The Example Audio Application can support a Right Headset If you have an extra 3rd Kit.

Now on to testing the audio example.

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.
