Hi PabloL,

Both options will give you what you want at the moment. What they lay out are a little different.

Having a sysbuild\ipc_radio\boards\nrf5340dk_nrf5340_cpunet.conf means that you can have different overlay files with different configurations for different boards.

Having all configs in sysbuild\ipc_radio\prj.conf means that you will have the same configurations for all boards.

You would want to consider which approach would match your needs.

Hi Hieu,

Thank you for the info.
I created a new application in VS Code and select the peripheral_uart sample.

The project dir tree is:

peripheral_uart
├── CMakeLists.txt
├── prj.conf
├── sysbuild.conf
├── nrf5340dk_app_sr_net.conf
├── boards
|   └── ...
├── src
|   └── main.c
├── build
|   └── ...
└── sysbuild
    └── ipc_radio
        ├── prj.conf
        └── prj_bt_rpc.conf

Should I create a new directory <prjdir>\sysbuild\hci_ipc\boards\ and add the file nrf5340dk_nrf5340_cpunet.conf?

Should I use one of the default directories and conf files?

Thanks!

Hi PabloL,

With sysbuild, the closest equivalent of child image Kconfig overlay file is: <prjdir>\sysbuild\hci_ipc\boards\nrf5340dk_nrf5340_cpunet.conf.

There is also <prj_dir>\sysbuild\hci_ipc\prj.conf. However, this replace the entire remote image's prj.conf file.
(In parent-child multi-image, this behavior is similar to <prj_dir>\child_image\hci_ipc\prj.conf).

For more information, please see Sysbuild (System build).
