Saving build configuration in a sysbuild project

[droberson]

Hello,

Sorry for the many tickets the past few days, but I am ramping up to start a nRF Connect SDK project on a nRF91 modem and have encountered some initial growing pains (And other bugs). Hopefully this will be my last one for a while since this is my remaining hurdle for starting a new project. I am new to Zephyr and the NRF Connect SDK.

• OS: Windows 11
• SDK/Toolchain: 2.9.0

From my understanding, it is not possible to save a build configuration in the nRF Connect VS Code extension per this guide: https://docs.nordicsemi.com/bundle/nrf-connect-vscode/page/guides/build_config.html#how-to-save-a-build-configuration-as-a-preset

From the guide "Sysbuild configurations cannot be saved as presets".

There are a bunch of configuration options in the build configuration wizard. If there is no way to save this when sharing a project via version control, it is prone to user error of selecting the wrong configuration items, resulting in the application building differently for different developers, which obviously is not good.

I am looking for a workaround for this.

Question:  Since the nRF Connect extension cannot save the build configuration for sysbuild projects, what CLI commands can I use to generate the build configuration automatically with my predefined board that the nRF Connect VS Code extension will then "see" when I edit the build configuration?

As a test, I captured the output when creating a build configuration using the nRF Connect extension. The only selection I made was to set the board to 'nrf9161dk/nrf9161/ns':

Building application
C:\Windows\system32\cmd.e x e /d /s /c "west build --build-dir c:/ncs_workspace/test_app/application/build c:/ncs_workspace/test_app/application --pristine --board nrf9161dk/nrf9161/ns --cmake-only -- -DNCS_TOOLCHAIN_VERSION=NONE"

-- west build: generating a build system ...

Please note that I had to space out the text cmd."e x e" in the above command because otherwise the Devzone would return the error "Could not create ticket" when trying to post it.

From the above, I created the following batch script and added the command above:

@echo off
set BOARD_NAME=nrf9161dk/nrf9161/ns
set BUILD_DIR=application/build
set APP_DIR=application

REM Clean existing build directory
if exist %BUILD_DIR% (
    echo Cleaning existing build directory...
    rmdir /s /q %BUILD_DIR%
)

REM Generate build configuration
echo Creating build configuration for board: %BOARD_NAME%
west build --build-dir %BUILD_DIR% %APP_DIR% --pristine --board %BOARD_NAME% --cmake-only -- -DNCS_TOOLCHAIN_VERSION=NONE

REM Check if build succeeded
if %ERRORLEVEL%==0 (
    echo Build configuration succeeded!
) else (
    echo Build configuration failed.
    exit /b 1
)

I run this in the nRF Connect terminal within VS Code. The build configuration succeeds with the following output:

PS C:\ncs_workspace\test_app>

I can see the build configuration in VS Code, yay!:

However, when I attempt to edit the build configuration with VS Code, I see the following (The board is incorrect):

Any idea why the configurator doesn't display the correct board and shows the yellow text warning? Any suggestions on how I can achieve my goal?

Thanks,

Derek

Hi,

Are you able to find your board from drop-down list or by typing your board name in the board target field?

Best regards,
Dejan

Hey Dejan,

Yes, I can build projects fine using the build configuration wizard built into the nRF Connect extension. I am building for a nRF9161DK. I am trying to figure out how I can save this build configuration such that it can be committed to version control and reused by other developers.

Thanks,

Derek

I have reported this issue internally. We will look into it further. I will get back to you during next week.

Hey dejans 

Any update on this?

Thanks,

Hi Derek,

I am sorry for a delayed reply. Unfortunately, there are no updates yet, but I have reached out to relevant team again. I will get back to you with status update by the end of the week.

Best regards,
Dejan
