OpenOCD to RustRover

OpenOCD to RustRover

While RustRover doesn't have built-in embedded Rust support like some other IDEs, you can still set up debugging through several approaches:

## Method 1: Using GDB Integration

1. **Start OpenOCD separately**:
   ```bash
   openocd -f interface.cfg -f target.cfg
   ```

2. **In RustRover**:
   - Go to `Run > Edit Configurations`
   - Add a new `GDB Remote Debug` configuration
   - Set the target to your ELF file
   - Configure GDB to connect to OpenOCD (usually port 3333)

## Method 2: Custom External Tool

1. **Set up OpenOCD as an external tool**:
   - Go to `File > Settings > Tools > External Tools`
   - Add OpenOCD with the appropriate command
   - You can run this before debugging sessions

## Method 3: Using Cargo Tools

If you're using `cargo-embed` or `probe-rs`:
- These tools can often handle both flashing and debugging
- You can set up custom run configurations that call these tools

## Recommended Setup

For the best experience, I'd suggest:

1. **Use probe-rs** (modern alternative to OpenOCD for ARM Cortex-M):
   ```bash
   cargo install probe-rs --features cli
   ```

2. **Create a custom run configuration** that runs:
   ```bash
   probe-rs run --chip <your-chip> target/thumbv7m-none-eabi/debug/your-app
   ```

## Current Limitations

- RustRover doesn't have built-in embedded target configuration like CLion
- You'll need to manually set up GDB and OpenOCD integration
- Peripheral view and other embedded-specific features aren't available

## Alternative Consideration

If you need robust embedded debugging, you might also consider:
- **CLion** with Rust plugin (better embedded support)
- **VS Code** with rust-analyzer and cortex-debug extensions

Would you like me to walk you through setting up any of these specific approaches?
