nRF5340 sysbuild network core port question

[adunk]

I am porting nRF SDK 2.6.1 to SDK 2.7.0 on the nRF5340. For the network core, where exactly should the kconfig (prj.conf) file be located and named? On the sysbuild migration guide I see it listed under the project->sysbuild->net_app.conf but that doesn't seem to get implemented into the project. I have also seen examples with the folder structure project->sysbuild->net_app->prj.conf where there is a folder for each project that is not the application project. This includes an mcuboot folder (which I'll also need). The only way I have got the kconfig settings to work are to put the prj.conf file within the network core application folder itself in the workspace->nrf->applications which doesn't make sense because this is a West based workspace, so this would get overwritten on a west update.

I am using the nrf Connect Extension on VSCode to build. Thanks!

Hello,

The name of the "net_app" folder in project->sysbuild->net_app->prj.conf must correspond with the name of network application. Bluetooth applications, for instance, will typically include the IPC radio firmware which is named ipc_radio and here is an example of how we can overrides the default configurations for this FW: https://github.com/nrfconnect/sdk-nrf/blob/v2.7.0/samples/bluetooth/throughput/sysbuild/ipc_radio/prj.conf 

We also have a section on sysbuild in your devacademy course here which may be helpful:  https://academy.nordicsemi.com/courses/nrf-connect-sdk-intermediate/lessons/lesson-8-sysbuild/ 

Best regards,
