There is no network interface to work with!

[3Nigma]

Hey there!

I'm trying to run the 'wifi/shell' sample on v3.0.1 on a nrf7002dk (targeting the nrf7002dk/nrf5340/cpuapp) with sysbuild enabled, of course and I'm getting the following logs:

[00:00:00.256,011] <err> net_if: There is no network interface to work with!
*** Booting nRF Connect SDK v3.0.1-9eb5615da66b ***
*** Using Zephyr OS v4.0.99-77f865b8f8d0 ***

Following this, any wifi sub-commands that I ran leads to a bus fault being logged.

I've also noticed that disabling sysbuild fixes this, although the memory footprint goes 3x the sysbuild values. Unfortunately, I can't disable sysbuild for my project if I were to go with 3.0.1 because I use the partition manager subsys and that looks like it's only working with sysbuild now.

Any workaround to this?

Thank you,

Vic

Hi Vic,

Have you made any changes to the SDK code or the sample?

What version of the DK do you have? You can find this on the white sticker on the DK.

Please do a pristine build and share the complete build log.

Best regards,
Marte

Hey Marte,

No no. Everything should be vanilla on my end: SDK v3.0.1 and toolchain on v3.0.1.

The DK of PCA10143 is versioned at 0.7.2 .

Here is the console build log (please tell me if you need any other build logs):

Hi,

Your .config is missing some configs, and sysbuild.conf is not included in the build.

In the build log, _sysbuild/empty.conf should be merged with sysbuild.conf, like this:

Loaded configuration '/home/mamy/ncs/nrf/samples/wifi/shell/build/_sysbuild/empty.conf'
Merged configuration '/home/mamy/ncs/nrf/samples/wifi/shell/sysbuild.conf'

But in your case, it is merged with _sysbuild/empty.conf instead:

Loaded configuration '/home/vic/ncs/v3.0.1/zephyr/samples/net/wifi/shell/build/_sysbuild/empty.conf'
Merged configuration '/home/vic/ncs/v3.0.1/zephyr/samples/net/wifi/shell/build/_sysbuild/empty.conf'

Can you verify that you have a sysbuild.conf file in the sample directory with the following Kconfig?

SB_CONFIG_WIFI_NRF70=y

Best regards,
Marte

Thank you, Marte!

Will give it a go and come back with the results.

Best wishes,

Thank you, Marte! That was it!

I thought that just enabling sysbuild would be enough to be able to run zephyr samples. I saw know somewhere in the docs that it isn't. Only the nrf samples can be run this way.

Anyway, thank you very much for assisting.

Have a nice day,

Vic
