BOOT_SWAP_USING_MOVE set more than once.

simonhwm

I have just upgraded my project to NCS 3.1.0 and I'm now getting this error

BOOT_SWAP_USING_MOVE (defined at C:/ncs/v3.1.0/bootloader/mcuboot/boot/zephyr/Kconfig:575) set more than once.

If I look at that file in the build directory I do indeed see conflicting settings

# sysbuild controlled configuration settings
...
CONFIG_SINGLE_APPLICATION_SLOT=n
CONFIG_BOOT_SWAP_USING_MOVE=n
CONFIG_BOOT_SWAP_USING_SCRATCH=n
CONFIG_BOOT_UPGRADE_ONLY=n
...
CONFIG_SINGLE_APPLICATION_SLOT=n
CONFIG_BOOT_SWAP_USING_OFFSET=n
CONFIG_BOOT_SWAP_USING_SCRATCH=n
CONFIG_BOOT_UPGRADE_ONLY=n
CONFIG_BOOT_SWAP_USING_MOVE=y
...
I don't set these values in my own config file as far as I can tell, so looks like this conflict comes from NCS 3.1.0 itself
Am I doing something wrong?

    Hello Simon!

    Based on the Kconfig you list and since you have MCUboot my guess is that you have one config that sets CONFIG_BOOT_SWAP_USING_MOVE=n and one that sets CONFIG_BOOT_SWAP_USING_MOVE=y. It could be something in the project configuration that implies (which is stronger than selecting or declaring) a Kconfig. An example of such a config isthe CONFIG_NCS_SAMPLE_ configurations, such as https://docs.nordicsemi.com/bundle/ncs-latest/page/kconfig/index.html#CONFIG_NCS_SAMPLE_MCUMGR_BT_OTA_DFU.

    Could you either share your prj.conf, sysbuild.conf as well as sysbuild<companion component>/prf.conf? 

    Do you get these warnings for a custom board, or is it from a custom board that pulls in certain configurations from a Kconfig file (for instance through an "Ifdefine <this board> use these kconfigs for configurations")?

    Kind regards,
    Andreas

    Hi,

    No unfortunately not. I spent a bit last week and again today attempting to recreate what you see and I can't find a configuration that triggers this behavior.

    You mention that you see the behavior when doing a pristine build. Do you also see the same when deleting the existing build folders before rebuilding? If yes, do you have a minimal sample that reproduces on a 52840DK?

    Kind regards,
    Andreas

    Just to add, I'm also seeing this while upgrading our project.

    It persists across pristine build/deleting build folder/etc.

    Looking in `build/mcuboot/zephyr/.config.sysbuild`, there are indeed two entries for `CONFIG_BOOT_SWAP_USING_MOVE`

    I suspect this is `zephyr/share/sysbuild/image_configurations/BOOTLOADER_image_default.cmake` and `nrf/sysbuild/CMakeLists.txt` fighting.

    This patch fixed the issue for me:

    Adding, though, that it is still defined twice.

    Just that both are set to the same value now.
