+
+## Building
+
+### For Cortex-M7 devices (CYT4BF, CYT4DN)
+```bash
+cargo build --target thumbv7em-none-eabi --features traveo-cyt4bf
+```
+
+### For Cortex-M0+ devices (CYT2B7, CYT2B9)
+```bash
+cargo build --target thumbv6m-none-eabi --features traveo-cyt2b7
+```
+
+### Release builds
+```bash
+cargo build --release --target thumbv7em-none-eabi --features traveo-cyt4bf
+```
+
+## Debugging
+
+1. Connect your Traveo II development board
+2. Start OpenOCD:
+   ```bash
+   openocd -f openocd.cfg -f traveo-cyt4bf.cfg
+   ```
+3. In VSCode, use `F5` or go to Run and Debug panel
+4. Select the appropriate debug configuration:
+   - "Debug Traveo (Cortex-M7)" for CYT4BF/CYT4DN
+   - "Debug Traveo (Cortex-M0+)" for CYT2B7/CYT2B9
+
+## Memory Configuration
+
+- **Cortex-M7**: 6MB Flash, 512KB RAM, 64KB TCM
+- **Cortex-M0+**: 2MB Flash, 256KB RAM
+
+## Troubleshooting
+
+1. **OpenOCD not found**: Ensure OpenOCD is installed and in your PATH
+2. **Target not found**: Check that your development board is connected and powered
+3. **Build errors**: Make sure you have the correct target and features selected
+
+## Development Tips
+
+1. Use `panic-halt` for production code (default)
+2. Use `semihosting` feature for debugging output during development
+3. Memory regions can be customized in `memory.x` and `memory-m0.x` files
+4. Add device-specific configurations in the respective `.cfg` files
+
+## Next Steps
+
+1. Update the memory configurations for your specific device
+2. Add device-specific HAL code in `src/main.rs`
+3. Configure OpenOCD for your specific development board
+4. Add any additional dependencies needed for your application

+# RustRover Setup for Infineon Traveo II Debugging
+
+This document provides instructions for setting up RustRover to replicate the VSCode debugging experience for Infineon Traveo II microcontrollers.
+
+## Prerequisites
+
+1. **RustRover IDE** installed
+2. **GNU Arm Embedded Toolchain** installed at `C:/Program Files (x86)/GNU Arm Embedded Toolchain/10 2021.10/bin`
+3. **OpenOCD** installed and available in PATH
+4. **ST-Link debugger** connected to your target hardware
+
+## Project Structure
+
+The converted configurations support two target architectures:
+- **Cortex-M7**: `thumbv7em-none-eabi` with `traveo-cyt4bf` feature
+- **Cortex-M0+**: `thumbv6m-none-eabi` with `traveo-cyt2b7` feature
+
+## Run/Debug Configurations
+
+The following configurations have been created in `.idea/runConfigurations/`:
+
+### Debug Configurations
+
+1. **Debug Traveo (Cortex-M7)**
+   - OpenOCD configuration: `interface/stlink.cfg;target/stm32f7x.cfg`
+   - GDB port: 3333
+   - Builds with: `thumbv7em-none-eabi` target and `traveo-cyt4bf` feature
+
+2. **Debug Traveo (Cortex-M0+)**
+   - OpenOCD configuration: `interface/stlink.cfg;target/stm32f0x.cfg`
+   - GDB port: 3333
+   - Builds with: `thumbv6m-none-eabi` target and `traveo-cyt2b7` feature
+
+3. **Attach to OpenOCD**
+   - For connecting to an already running OpenOCD instance
+   - GDB port: 3333
+
+### Build Configurations
+
+1. **Build Traveo (Cortex-M7)**
+   - Command: `cargo build --target thumbv7em-none-eabi --features traveo-cyt4bf`
+
+2. **Build Traveo (Cortex-M0+)**
+   - Command: `cargo build --target thumbv6m-none-eabi --features traveo-cyt2b7`
+
+## Setup Instructions
+
+### 1. Open Project in RustRover
+1. Launch RustRover
+2. Open the project directory
+3. Ensure Cargo.toml is detected as a Rust project
+
+### 2. Configure Toolchains
+1. Go to **File > Settings > Languages & Frameworks > Rust**
+2. Ensure the correct toolchain is selected for embedded development
+3. Add the GNU Arm Embedded Toolchain to your system PATH if not already present
+
+### 3. Import Run Configurations
+The run configurations are already created in `.idea/runConfigurations/`. They should be automatically detected by RustRover.
+
+### 4. Verify OpenOCD Installation
+1. Open a terminal in RustRover
+2. Run `openocd --version` to verify installation
+3. Ensure ST-Link drivers are installed
+
+### 5. Hardware Setup
+1. Connect your ST-Link debugger to the target board
+2. Ensure proper power supply and connections
+3. Verify the target board is recognized by OpenOCD
+
+## Usage
+
+### Building
+1. Select the appropriate build configuration from the run configurations dropdown
+2. Click the run button or press Shift+F10
+3. The project will build for the selected target architecture
+
+### Debugging
+1. Select the appropriate debug configuration (Cortex-M7 or Cortex-M0+)
+2. Click the debug button or press Shift+F9
+3. RustRover will:
+   - Build the project with the appropriate features
+   - Start OpenOCD with the correct configuration
+   - Launch the debugger and connect to the target
+
+### Attaching to Running OpenOCD
+1. Start OpenOCD manually in a terminal:
+   ```bash
+   openocd -f interface/stlink.cfg -f target/stm32f7x.cfg -c "adapter speed 1000" -c "init" -c "reset init" -c "cortex_m reset_config sysresetreq"
+   ```
+2. Select "Attach to OpenOCD" configuration in RustRover
+3. Click debug to connect to the running OpenOCD instance
+
+## Troubleshooting
+
+### Common Issues
+
+1. **OpenOCD not found**
+   - Ensure OpenOCD is installed and in your system PATH
+   - Restart RustRover after installing OpenOCD
+
+2. **ST-Link not recognized**
+   - Check ST-Link drivers installation
+   - Verify USB connections
+   - Try different USB port
+
+3. **Target not found**
+   - Check target board power and connections
+   - Verify OpenOCD configuration matches your hardware
+   - Check console output for error messages
+
+4. **Build errors**
+   - Ensure all required features are available in Cargo.toml
+   - Check that the correct toolchain is being used
+   - Verify target architecture matches your hardware
+
+### Debug Console
+Open the Debug console in RustRover to see detailed output from OpenOCD and GDB. This can help diagnose connection and configuration issues.
+
+## Advanced Configuration
+
+### Customizing OpenOCD Arguments
+To modify OpenOCD behavior, edit the run configuration and adjust the `OPENOCD_SERVER_ARGS` field:
+
+- Current: `--command "adapter speed 1000" --command "init" --command "reset init" --command "cortex_m reset_config sysresetreq"`
+- Modify adapter speed, initialization commands, or reset configuration as needed
+
+### Adding New Targets
+To add support for additional Traveo II devices:
+
+1. Add the feature to Cargo.toml
+2. Create a new build configuration with the appropriate target and features
+3. Create a corresponding debug configuration with the matching OpenOCD config files
+4. Update this documentation
+
+## Comparison with VSCode
+
+| Feature | VSCode (cortex-debug) | RustRover |
+|---------|----------------------|-----------|
+| Extension/Plugin | cortex-debug extension | Built-in Embedded Development |
+| Configuration | launch.json + tasks.json | XML run configurations |
+| OpenOCD Integration | Through cortex-debug | Native OpenOCD support |
+| Build Integration | Tasks system | Cargo command configurations |
+| Debugging Features | GDB integration | Full GDB debugging support |
+
+The RustRover configurations provide equivalent functionality to the VSCode setup while leveraging RustRover's native embedded development capabilities.
