Matter lamp example fails build with CONFIG_MCUBOOT_BOOTLOADER_MODE_DIRECT_XIP

[Sergey A.]

I'm trying to test direct XIP in DFU over BT in Matter lamp example on nRF52840 DK using SDK v 2.5.1 

In order to test direct XIP I created a project using the sample and added using the same added CONFIG_CHIP_DFU_OVER_BT_SMP=y and CONFIG_NCS_SAMPLE_MCUMGR_BT_OTA_DFU=y to prj.conf in order to enable DFU over BT. That worked quite well.

Then I tried to test direct XIP and, following Build configuration additions for MCUboot in the direct-xip mode documentation, I added 

CONFIG_BOOT_DIRECT_XIP=y to child_image\mcuboot\prj.conf and CONFIG_MCUBOOT_BOOTLOADER_MODE_DIRECT_XIP=y to prj.conf. When I tried to build the project I got this error

-- Found partition manager static configuration: C:/nordic/myapps/light_bulb_1/configuration/nrf52840dk_nrf52840/pm_static_dfu.yml -- Configuring done CMake Error at C:/nrf_sdk/v2.5.1/modules/lib/matter/config/nrfconnect/chip-module/generate_factory_data.cmake:163 (add_custom_command): Error evaluating generator expression: $<TARGET_PROPERTY:partition_manager,PM_FACTORY_DATA_ADDRESS>

Does this example support Direct XIP at all?

Hi Menon ,

Thank you for the example. I've already configured OTA BLE in the matter lamp example, it works as expected.

Looking forward to hearing from you about direct XIP with OTA BLE. 

Kind regards,

Sergey

Hello,

Sorry for the delay. I am working on the sample. I will update it here, probably by tomorrow.

Hello,

I am attaching a Peripheral_lbs sample with MCUboot direct_XIP and BLE FOTA configured. Can you test this and let me know if this works for you?

Hi Menon ,

Thank you very much for the sample! It seems like it is working as expected.

I still wonder why the original example doesn't work, what is so special about Matter Lamp example? Is it because it uses external flash and your example doesn't because both slots of firmware fit into internal flash?

Kind regards,

Sergey
