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

   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)

cargo build --target thumbv7em-none-eabi --features traveo-cyt4bf

For Cortex-M0+ devices (CYT2B7, CYT2B9)

cargo build --target thumbv6m-none-eabi --features traveo-cyt2b7

Release builds

cargo build --release --target thumbv7em-none-eabi --features traveo-cyt4bf

Debugging

1. Connect your Traveo II development board
2. Start OpenOCD:

   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
