RE: Update mcuboot (DFU) in SDK v2.7.0

Good to hear! The SB_CONFIG_SECURE_BOOT_MCUBOOT_VERSION string is used to sign the image for MCUboot, allowing MCUboot to copy the image to the s1/s0 slot, while CONFIG_FW_INFO_FIRMWARE_VERSION sets the version embedded in the MCUboot image that b0 uses.

It works, thank you !

What is the difference between SB_CONFIG_SECURE_BOOT_MCUBOOT_VERSION and CONFIG_FW_INFO_FIRMWARE_VERSION ?

Hello,

I'm experiencing the same issue when trying this with SDK v2.7.0. I will investigate further and keep you updated on the progress.

Best regards,

Vidar

Update: Please add SB_CONFIG_MCUBOOT_UPDATEABLE_IMAGES=2 and
SB_CONFIG_MCUBOOT_APP_SYNC_UPDATEABLE_IMAGES=n to your sysbuild configuration. The image number must be set to '2' for MCUBoot to be able to activate the MCUBoot image.

For example:

# https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/releases_and_maturity/migration/migration_sysbuild.html 
SB_CONFIG_BOOTLOADER_MCUBOOT=y
SB_CONFIG_SECURE_BOOT_APPCORE=y
SB_CONFIG_DFU_MULTI_IMAGE_PACKAGE_BUILD=y
SB_CONFIG_DFU_MULTI_IMAGE_PACKAGE_APP=y
SB_CONFIG_DFU_MULTI_IMAGE_PACKAGE_MCUBOOT=y

SB_CONFIG_SECURE_BOOT_MCUBOOT_VERSION="3.0.0+0"

SB_CONFIG_SECURE_BOOT_SIGNING_KEY_FILE="keys/nrf_bootloader.pem"
SB_CONFIG_BOOT_SIGNATURE_KEY_FILE="${APPLICATION_CONFIG_DIR}/keys/mcuboot_priv.pem"

# Settings required for external flash to be used for DFU
SB_CONFIG_PM_EXTERNAL_FLASH_MCUBOOT_SECONDARY=y
SB_CONFIG_PM_OVERRIDE_EXTERNAL_DRIVER_CHECK=y

SB_CONFIG_MCUBOOT_UPDATEABLE_IMAGES=2
SB_CONFIG_MCUBOOT_APP_SYNC_UPDATEABLE_IMAGES=n
