OpenThread on nRF5340 Audio DK

I'm running into a similar issue with trying to build the nRF Thread coprocessor project for the nRF5340. I'm able to compile the coprocessor project just fine for the nRF52840 and I can compile the CLI project for both the 52840 and 5340. But I keep getting errors when trying to build the coprocessor project for the 5340.

I created a new ticket for my issue- CASE ID: 312120

Glad to hear! It took me a while to figure it out. Learning by doing 🙂 Have a nice weekend!

Best regards,

Hello Håkon,

I understand. I suggest that you try with a stable version of NCS. v2.3.0 (non rc / release candidate) is released now, so I suggest you go over to that version.

However, I tested in v2.3.0, and I saw the same behavior as you did. The reason it doesn't build is because the device tree files for the audio DK doesn't claim that the chip has support for 802.15.4.

The way you can see what is already enabled is by looking at the nrf5340_audio_dk_nrf5340_cpuapp.dts and nrf5340_audio_dk_nrf5340_cpunet.dts, and compare it to the equivalent files for nrf5340dk_nrf5340_cpuapp/net.dts.

The best way to change this, without modifying the files themselves is to add an overlay file with the same name as the board you are using in your application folder. So in the same folder where you will find the CMakeLists.txt, add this file, called nrf5340_audio_dk_nrf5340_cpuapp.overlay

devzone.nordicsemi.com/.../2860.nrf5340_5F00_audio_5F00_dk_5F00_nrf5340_5F00_cpuapp.overlay

As you can see, I only added the parts missing about 802154. These will overwrite the default settings from the .dts file when you compile.

And since this is a dual core chip, we need to tell it that the network core also supports 802.15.4, which the nrf5340_audio_dk_nrf5340_cpunet board file doesn't claim that it has.

So create a file that has this path (where the "cli" folder still is the folder that contains your sample's CMakelists.txt file):

cli\child_image\802154_rpmsg\boards\nrf5340_audio_dk_nrf5340_cpunet.overlay. It should have this content:

devzone.nordicsemi.com/.../nrf5340_5F00_audio_5F00_dk_5F00_nrf5340_5F00_cpunet.overlay

Then, try to do a pristine build (or delete your build folder and rebuild from scratch).

Best regards,

Edvin

Hi Edvin,

I understand, currently I will just evaluate OpenThread without the concurrent (BLE + Thread) mode.

I open VScode and from the nRF Connect extension i created a new sample project "nrf/samples/openthread/cli"
in the build configuration i selected Nordic boards and then selected nrf5340_audio_dk_nRF5340_cpuapp, this was not listed under "Compatible boards" then i pressed build within the nRF Connect extension

I got this compile error:

C:\ncs\v2.3.0-rc1\zephyr\drivers\ieee802154\ieee802154_nrf5.c:47:10: fatal error: nrf_802154.h: No such file or directory
   47 | #include "nrf_802154.h"

Best regards,
Håkon

Hello,

I would assume. But it will not be possible to use the Audio over LE stack together with Thread, unfortunately.

[quote user=""]I got a compile error missing nrf_802154.h files.[/quote]

I don't know what/how you tried to compile. Would I be able to reproduce what you are seeing? If so, how?

Best regards,

Edvin
