defunct: playing around with bootloaders

- Corrected device tree overlays to prevent MCUboot and app overlap
- MCUboot now at 0x8000000 (32KB), app at 0x8008000 (96KB)
- Successfully boots MCUboot which chains to application
- Shell and reset command working properly
- Black Magic Probe flashing confirmed working for both domains

 * **Mikrocontroller:** Ein `STM32G431PB`. Dieser ist zwar leistungsstark, bietet aber alle nötigen Peripherien (mehrere UARTs, ADCs, CAN) und ermöglicht ein einheitliches Hardware- und Software-Design.

-    * **Zwei High-Side Ausgänge (+12V):** Realisiert über einen `VND7050AJ`. Perfekt zur Ansteuerung der 12V-Motorventile (`Öffnen`/`Schliessen`). Die `Sense`-Leitung des Treibers wird über einen AD-Wandler ausgelesen, um durch Messung des Motorstroms eine Endlagen-Erkennung ohne physische Endschalter zu realisieren (Motorstrom im Stillstand ≈ 0). Zusätzlich können die Temperatur und die Versorgungsspannung des Treibers ausgelesen werden.

     * **Zwei Low-Side Ausgänge (0V):** Über N-Kanal-MOSFETs geschaltete Ausgänge. Nutzbar zur Ansteuerung von 12V-LEDs in Tastern oder zum Schalten des Halbleiter-Relais für die Pumpe.

+.. zephyr:code-sample:: adc_dt
+   :name: Analog-to-Digital Converter (ADC) with devicetree
+   :relevant-api: adc_interface
+
+   Read analog inputs from ADC channels.
+
+Overview
+********
+
+This sample demonstrates how to use the :ref:`ADC driver API <adc_api>`.
+
+Depending on the target board, it reads ADC samples from one or more channels
+and prints the readings on the console. If voltage of the used reference can
+be obtained, the raw readings are converted to millivolts.
+
+The pins of the ADC channels are board-specific. Please refer to the board
+or MCU datasheet for further details.
+
+Building and Running
+********************
+
+The ADC peripheral and pinmux is configured in the board's ``.dts`` file. Make
+sure that the ADC is enabled (``status = "okay";``).
+
+In addition to that, this sample requires an ADC channel specified in the
+``io-channels`` property of the ``zephyr,user`` node. This is usually done with
+a devicetree overlay. The example overlay in the ``boards`` subdirectory for
+the ``nucleo_l073rz`` board can be easily adjusted for other boards.
+
+Configuration of channels (settings like gain, reference, or acquisition time)
+also needs to be specified in devicetree, in ADC controller child nodes. Also
+the ADC resolution and oversampling setting (if used) need to be specified
+there. See :zephyr_file:`boards/nrf52840dk_nrf52840.overlay
+<samples/drivers/adc/adc_dt/boards/nrf52840dk_nrf52840.overlay>` for an example of
+such setup.
+
+Building and Running for ST Nucleo L073RZ
+=========================================
+
+The sample can be built and executed for the
+:zephyr:board:`nucleo_l073rz` as follows:
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/drivers/adc/adc_dt
+   :board: nucleo_l073rz
+   :goals: build flash
+   :compact:
+
+To build for another board, change "nucleo_l073rz" above to that board's name
+and provide a corresponding devicetree overlay.
+
+Sample output
+=============
+
+You should get a similar output as below, repeated every second:
+
+.. code-block:: console
+
+   ADC reading:
+   - ADC_0, channel 7: 36 = 65mV
+
+.. note:: If the ADC is not supported, the output will be an error message.

+# Firmware Node Application
+
+This Zephyr application provides firmware management capabilities for the irrigation system.
+
+**Tested on Zephyr 4.1.99**
+
+## Features
+
+### Step 1: Shell with Reset Command
+- Shell interface with custom "reset" command
+- Warm reboot functionality
+
+### Planned Features
+- MCUboot support with partition manager
+- Firmware version display
+- MCUmgr support for OTA updates
+
+## Building
+
+```bash
+west build -p auto -b weact_stm32g431_core apps/firmware_node -- -DBOARD_FLASH_RUNNER=blackmagicprobe
+```
+
+## Flashing
+
+```bash
+west flash
+```
+
+## Usage
+
+Connect to the device via serial console and use the shell:
+- `reset` - Reboot the system
+- `help` - Show available commands

-# README for the Hello World Zephyr Application
-
-## Overview
-
-This is a minimal Hello World application built using the Zephyr RTOS. The application demonstrates basic logging functionality by printing a message every 5 seconds, including the version number of the application.
-
-## Project Structure
-
-The project consists of the following files:
-
-- `src/main.c`: The entry point of the application that initializes logging and sets up a timer.
-- `include/app_version.h`: Header file that defines the application version.
-- `VERSION`: A text file containing the version number of the application.
-- `prj.conf`: Configuration file for the Zephyr project, specifying necessary options.
-- `CMakeLists.txt`: Build configuration file for CMake.
-- `README.md`: Documentation for the project.
-
-## Building the Application
-
-To build the application, follow these steps:
-
-1. Ensure you have the Zephyr development environment set up.
-2. Navigate to the `apps/gateway` directory.
-3. Run the following command to build the application:
-
-   ```
-   west build -b <your_board> .
-   ```
-
-   Replace `<your_board>` with the appropriate board name.
-
-## Running the Application
-
-After building the application, you can flash it to your board using:
-
-```
-west flash
-```
-
-Once the application is running, you will see log messages printed every 5 seconds, including the version number.
-
-## Version
-
-The version of this application can be found in the `VERSION` file and is also included in the log messages.

+# Firmware Node Application
+
+This Zephyr application provides firmware management capabilities for the irrigation system.
+
+**Tested on Zephyr 4.1.99**
+
+## Features
+
+### Step 1: Shell with Reset Command
+- Shell interface with custom "reset" command
+- Warm reboot functionality
+
+### Planned Features
+- MCUboot support with partition manager
+- Firmware version display
+- MCUmgr support for OTA updates
+
+## Building
+
+```bash
+west build -p auto -b weact_stm32g431_core apps/firmware_node -- -DBOARD_FLASH_RUNNER=blackmagicprobe
+```
+
+## Flashing
+
+```bash
+west flash
+```
+
+## Usage
+
+Connect to the device via serial console and use the shell:
+- `reset` - Reboot the system
+- `help` - Show available commands
