Hello,

It looks like you have not updated the application to use sysbuild, which was introduced in 2.7.0.

Sysbuild is a new building system, where we went away from the traditional child image configuration, to using sysbuild.

One option, is to add this to disable sysbuild. If you are using command line, just add --no-sysbuild, as an argument, and if you use VS Code, there is a choise in the botttom of the "add build configuration" tab, where you can choose between "Use sysbuild" and "No sysbuild".

For debugging purposes, you can see if this alone lets you build the application, and if it runs as expected.

However, if you plan to port to NCS v3.0.0 when that is released, you need to use sysbuild, becaue the "no sysbuild" option, and the old child image build configuration will be deprecated.

In that case, I suggest that you read the migration guides for all the major releases between 2.6.0 and 2.9.0 (and eventually 3.0.0).

You can find them here:

https://docs.nordicsemi.com/bundle/ncs-2.9.0/page/nrf/releases_and_maturity/migration_guides.html

And let me know if you have any follow-up questions.

Best regards,

Edvin
