Hello.
I am currently migrating a project from NCS v3.2.4 to v3.3.1 and transitioning from Partition Manager to devicetree-based partitioning, following the official migration guide:
https://nrfconnectdocs.nordicsemi.com/ncs/latest/nrf/releases_and_maturity/migration/migration_partitions.html
While the build process succeeds using the generated .overlay files, the application fails to boot after MCUboot.
It enters a continuous reboot loop.
Serial Terminal Log:
*** Booting MCUboot v2.3.0-dev-3de5b4df5f9f *** *** Using nRF Connect SDK v3.3.1-1d7a0b0e49b8 *** *** Using Zephyr OS v4.3.99-37e6c28576ee *** I: Starting bootloader I: Image index: 0, Swap type: none I: Bootloader chainload address offset: 0x14000 I: Image version: v0.3.0 I: Jumping to the first image slot *** Booting MCUboot v2.3.0-dev-3de5b4df5f9f *** ... (loop repeats)
Configuration Details:
- Device: nRF54L15
- Setup: MCUboot + TF-M
- Context: I have been unable to find specific examples for an nRF54L15 setup with both MCUboot and TF-M using the new devicetree partitioning method.
Attached Files:
- pm_static.yml: Original working partition configuration.
- generate.overlay: Generated via pm_to_dts.py.
- app.overlay: Modified version of the generated file
(removed redundant nodes, and manually adjusted cpuapp_sram to reflect previous Kconfig settings:
CONFIG_PM_PARTITION_SIZE_TFM=0x1F800 and CONFIG_PM_PARTITION_SIZE_TFM_SRAM=0x10000). - mcuboot.overlay: File used for MCUboot.

Could you please review my configuration and advise on the correct approach for setting up devicetree partitions in an nRF54L15 MCUboot/TF-M environment?
