# 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
