# arm-hello
This is an Hello-World-OS in Rust running on the `aarch64` architecture.
This project is written purely in Rust using inline assembly for startup.
## Build and run
This project depends on
- [Rust](https://www.rust-lang.org)
- [Xargo](https://github.com/japaric/xargo)
- [QEMU](https://www.qemu.org/)
- [Aarch64-Toolchain](https://packages.ubuntu.com/de/trusty/gcc-aarch64-linux-gnu)
If you have installed these, just run
```
> make run
```
## Resources
Because there is no such thing as a VGA-Buffer for this architecture, output is printed to the serial console through the port UART0, which QEMU supports through the `-nographic` or `-serial stdio` options.
This [post][1] for ARM bare metal coding in `C` was really helpful for getting a grasp of it.
This [bootloader][2] project from Philipp Oppermann helped finding out how to embed assembly in rust. For more OS-stuff there is his awesome series [Writing an OS in Rust][2].
