Pictures
It paints the screen bright red and then displays some information. You can write. That's it:
Setup
You need a few things to run rustboot:
- Rust's
masterbranch - qemu
- On x86
- clang
- nasm
- On ARM
- binutils for arm-none-eabi
- gcc cross-compiler
- Optionally for debugging
- gdb
- tmux
Clone this repository.
$ git clone https://github.com/pczarn/rustboot.git
$ cd rustboot
To get edge Rust going, grab it from git:
$ git clone https://github.com/mozilla/rust
$ cd rust
$ ./configure --target=i686-unknown-linux-gnu
$ make && make install
You can considerably minimize build time:
$ ./configure --target=i686-unknown-linux-gnu --llvm-root=/usr
$ make rustc-stage1
Then use the rust/*/stage1/bin/rustc binary to compile rustboot:
$ echo "RUST_ROOT:=$(pwd)/x86_64-unknown-linux-gnu/stage1/bin" > rustboot/config.mk
Arch Linux
Simply install all dependencies:
# pacman -S qemu nasm rust clang gdb tmux
# yaourt -S gcc-arm-none-eabi
OSX
To set things up on OSX, do this:
Install nasm and qemu from homebrew:
$ brew install nasm
$ brew install qemu
Install latest binutils from source.
$ wget 'ftp://sourceware.org/pub/binutils/snapshots/binutils.tar.bz2'
$ ./configure --target=i386-elf
$ make && make install
Running it
To compile, simply execute make command.
To run, use:
$ make run # emulate default platform (x86)
$ make arch=arm run # run on ARM
$ make arch=arm debug # debug on ARM
