Cross-compiling Rust for the Q7S
======

# Build with `cargo`

Build debug image: 

```sh
cargo build --target armv7-unknown-linux-gnueabihf
```

You can then transfer the application with `scp`. It is recommended to use
the `q7s-cp.py` utility which is part of the
[EIVE OBSW script folder](https://egit.irs.uni-stuttgart.de/eive/eive-obsw).

If you use this script, you can use the `deploy-q7s.sh` script to deploy the
binary conveniently.

# Prerequisites

1. Install rust on your development machine using `rustup`

   ```sh
   curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
   ```

2. Install standard library for target architecture

	```sh
	rustup target add armv7-unknown-linux-gnueabihf
   ```

3. Install a cross-compile toolchain for the Cortex-A9 target and add it to your path.
   It is recommended to take the same toolchain used to compile the Q7S primary OBSW.
   See the [dedicated README](https://egit.irs.uni-stuttgart.de/eive/eive-obsw)
   for more details and download links.

4. Install `sshpass`

   ```sh
   sudo apt-get install sshpass
   ```
