Sysbuild forced options

Sysbuild controls some Kconfig options in images that are part of a project. This means that these Kconfig options can only be changed from within sysbuild itself and cannot be changed directly in an image. Trying to change them directly in an image will result in the new value being overwritten with the sysbuild value.

Note

The Partition Manager is a component in the nRF Connect SDK and is responsible for handling the memory partitioning at build time.

This functionality is in the process of being deprecated and replaced by Zephyr’s default devicetree-based memory partitioning. It is recommended that all new designs using Nordic devices, excluding the nRF91 Series devices, are to be built with DTS instead of Partition Manager. Partition Manager will be removed from the nRF Connect SDK by the end of 2026 from the main branch.

For more information on how to configure partitions using DTS and how to migrate your existing configuration to DTS, see the following pages:
