sysbuild_kconfig

Sysbuild’s own Kconfig configuration.

Sysbuild has a Kconfig tree of its own, rooted at the application’s Kconfig.sysbuild file and namespaced under SB_CONFIG_ so that it cannot collide with an image’s own CONFIG_ options. See Kconfig namespacing.

This module locates the sysbuild configuration files and runs Kconfig over them. It also defines the sysbuild_menuconfig and sysbuild_guiconfig build targets, which edit sysbuild’s own configuration rather than that of any image.

Configuration input files are looked up in SB_APPLICATION_CONFIG_DIR, falling back to APPLICATION_CONFIG_DIR, and are controlled by:

• SB_CONF_FILE

• SB_EXTRA_CONF_FILE
