+Multicore idle test with firmware relocated to radio core TCM
+#############################################################
+
+.. contents::
+   :local:
+   :depth: 2
+
+The test benchmarks the idle behavior of an application that runs on multiple cores.
+It demonstrates a radio loader pattern where the radio core firmware is loaded from MRAM into TCM (Tightly Coupled Memory) at runtime.
+
+Requirements
+************
+
+The test supports the following development kit:
+
+.. table-from-rows:: /includes/sample_board_rows.txt
+   :header: heading
+   :rows: nrf54h20dk_nrf54h20_cpuapp
+
+Overview
+********
+
+This test demonstrates how to build a multicore idle application with :ref:`configuration_system_overview_sysbuild` using a two-stage boot process for the radio core:
+
+* Radio Loader - A small bootloader that runs on the radio core, copies firmware from MRAM to TCM, and jumps to it.
+* Remote Firmware - The actual application that runs from TCM after being loaded.
+
+The test automatically relocates the remote firmware binary to the correct MRAM address during build time, ensuring it can be loaded by the radio loader.
+
+Architecture
+============
+
+The system uses the following memory layout:
+
+* **MRAM (Non-volatile):**
+
+  * ``cpurad_loader_partition`` @ 0x92000 - Contains the radio loader (8 KB)
+  * ``cpurad_loaded_fw`` @ 0x94000 - Contains the remote firmware binary (128 KB)
+
+* **TCM (Volatile, fast execution):**
+
+  * ``cpurad_ram0`` @ 0x23000000 - Code execution region (128 KB)
+  * ``cpurad_data_ram`` @ 0x23020000 - Data region (64 KB)
+
+Additional files
+================
+
+The test comes with the following additional files:
+
+* :file:`sysbuild.conf` - Enables the radio loader by setting ``CONFIG_NRF_RADIO_LOADER=y``.
+* :file:`boards/memory_map.overlay` - Shared memory map configuration for both loader and remote firmware.
+* :file:`sysbuild/radio_loader/` - Radio loader configuration overrides (:file:`prj.conf`, overlay).
+* :file:`sysbuild/remote_rad/` - Radio core firmware configuration overrides (:file:`prj.conf`, overlay).
+
+Enabling the Radio Loader
+*************************
+
+The radio loader is automatically added to the build when you enable it in sysbuild configuration.
+
+In :file:`sysbuild.conf`:
+
+.. code-block:: kconfig
+
+   SB_CONFIG_NRF_RADIO_LOADER=y
+
+This single configuration option:
+
+#. Automatically adds the ``radio_loader`` application located in the :file:`nrf/samples/nrf54h20/radio_loader` folder.
+#. Builds it for the CPURAD core.
+#. No manual ``ExternalZephyrProject_Add()`` needed in sysbuild.
+
+Memory map configuration
+========================
+
+The memory map is defined in :file:`boards/memory_map.overlay` and is shared between the radio loader and remote firmware to ensure consistency.
+
+The overlay defines:
+
+#. TCM regions:
+
+   .. code-block:: devicetree
+
+      cpurad_ram0: sram@23000000 {
+          compatible = "mmio-sram";
+          reg = <0x23000000 0x20000>;  /* 128 KB for code */
+      };
+      cpurad_data_ram: sram@23020000 {
+          compatible = "mmio-sram";
+          reg = <0x23020000 0x10000>;  /* 64 KB for data */
+      };
+
+#. MRAM partitions:
+
+   .. code-block:: devicetree
+
+      &mram1x {
+          /delete-node/ partitions;
+
+          partitions {
+              compatible = "fixed-partitions";
+              #address-cells = <1>;
+              #size-cells = <1>;
+
+              cpurad_loader_partition: partition@92000 {
+                  label = "cpurad_loader_partition";
+                  reg = <0x92000 DT_SIZE_K(8)>;  /* 8 KB allocated (~4 KB actual) */
+              };
+
+              cpurad_loaded_fw: partition@94000 {
+                  label = "cpurad_loaded_fw";
+                  reg = <0x94000 DT_SIZE_K(128)>;  /* 128 KB fixed */
+              };
+          };
+      };
+
+Automatic firmware relocation
+*****************************
+
+The remote firmware must be relocated to match the MRAM partition address where it will be stored.
+This is automatically done by Zephyr's ``CONFIG_BUILD_OUTPUT_ADJUST_LMA`` feature when the devicetree chosen nodes are configured correctly.
+
+How it works
+============
+
+Firmware relocation is handled automatically by Zephyr's build system using the ``CONFIG_BUILD_OUTPUT_ADJUST_LMA`` configuration option, which is configured in ``zephyr/soc/nordic/nrf54h/Kconfig.defconfig.nrf54h20_cpurad`` for all nRF54H20 CPURAD projects.
+
+The configuration automatically detects the ``fw-to-relocate`` chosen node in your devicetree.
+When present, it calculates the LMA adjustment to relocate firmware from MRAM to TCM.
+Without this chosen node, firmware runs directly from the ``zephyr,code-partition`` location (standard XIP behavior).
+
+Simply configure the devicetree chosen nodes correctly in your firmware's overlay:
+
+.. code-block:: devicetree
+
+   /{
+       chosen {
+           /* VMA: where code runs (TCM) */
+           zephyr,code-partition = &cpurad_ram0;
+           zephyr,sram = &cpurad_data_ram;
+
+           /* LMA: where to load from (MRAM partition) - enables relocation */
+           fw-to-relocate = &cpurad_loaded_fw;
+       };
+   };
+
+Zephyr automatically calculates the Load Memory Address (LMA) adjustment based on your chosen nodes:
+
+**With fw-to-relocate chosen node** (for radio loader pattern):
+
+.. code-block:: text
+
+   LMA_adjustment = fw-to-relocate address - zephyr,code-partition address
+                  = cpurad_loaded_fw - cpurad_ram0
+                  = 0x94000 - 0x23000000
+
+**Without fw-to-relocate** (standard behavior):
+
+.. code-block:: text
+
+   LMA_adjustment = zephyr,code-partition address - zephyr,sram address
+
+The build system then adjusts the hex file so that the firmware is loaded from MRAM (``0x94000``), but runs from TCM (``0x23000000``).
+
+Building and running

+.. |test path| replace:: :file:`samples/nrf54h20/idle_relocated_tcm`

+
+Testing
+=======
+
+After programming the test to your development kit, complete the following steps to test it:
+
+1. |connect_terminal|
+#. Reset the kit.
+#. Observe the console output for both cores:
+
+   * For the application core, the output should be as follows:
+
+     .. code-block:: console
+
+       *** Booting nRF Connect SDK zephyr-v3.5.0-3517-g9458a1aaf744 ***
+       build time: Nov 22 2025 17:00:59
+       Multicore idle test on nrf54h20dk@0.9.0/nrf54h20/cpuapp
+       Multicore idle test iteration 0
+       Multicore idle test iteration 1
+       ...
+
+   * For the radio core, the output should be as follows:
+
+     .. code-block:: console
+
+       *** Booting nRF Connect SDK zephyr-v3.5.0-3517-g9458a1aaf744 ***
+       build time: Nov 22 2025 17:00:29

+       Current PC (program counter) address: 0x23000ae0
+       Multicore idle test iteration 0
+       Multicore idle test iteration 1
+       ...
+
+   The radio loader first loads the firmware from MRAM (``0x0e094000``) to TCM (``0x23000000``) and then jumps to the loaded firmware.
+   This process is transparent and happens during the early boot stage.
+
+#. Verify the DFU process:
+
+   #. Build the firmware for the secondary app slot, increase the version number in the :file:`prj.conf` file (uncomment the line):
+
+      .. code-block:: kconfig
+
+         CONFIG_MCUBOOT_IMGTOOL_SIGN_VERSION="0.0.1+0"
+
+   #. Build the firmware:
+
+      .. code-block:: console
+
+         west build -p -b nrf54h20dk/nrf54h20/cpuapp
+
+   #. Program the firmware to the secondary application slot:
+
+      .. code-block:: console
+
+         nrfutil device program --firmware build/zephyr_secondary_app.merged.hex  --options chip_erase_mode=ERASE_NONE
+
+   Reset the development kit.
+   The firmware must boot from the secondary application slot.
+   Observe the change in build time in the console output.

+	  (Tightly Coupled Memory) at boot time.
+
+	  The loader runs from MRAM and:
+	  - Copies firmware from MRAM partition to TCM
+	  - Jumps to the loaded firmware in TCM for optimal performance
+
+	  Requires devicetree memory map configuration with partitions
+	  and chosen nodes defined in the project's overlay files.
