+# Infineon Traveo II Rust Project
+
+This project is configured for developing applications on Infineon Traveo II microcontrollers using Rust.
+
+## Prerequisites
+
+### Required Tools
+
+1. **Rust Toolchain**
+   ```bash
+   rustup target add thumbv6m-none-eabi thumbv7em-none-eabi
+   rustup component add rust-src
+   ```
+
+2. **GNU Arm Embedded Toolchain**
+   - Download from: https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm
+   - Install to: `C:\Program Files (x86)\GNU Arm Embedded Toolchain\10 2021.10\`
+   - Add to PATH environment variable
+
+3. **OpenOCD**
+   - Download from: http://openocd.org/
+   - Ensure `openocd.exe` is in your PATH
+
+4. **VSCode Extensions**
+   - Cortex-Debug (marus25.cortex-debug)
+   - Rust Analyzer (rust-lang.rust-analyzer)
+
+## Supported Devices
+
+- **Cortex-M7 devices**: CYT4BF, CYT4DN series
+- **Cortex-M0+ devices**: CYT2B7, CYT2B9 series
+

+
+## 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
