# Programming language, compiler, and operating system for bare-metal ARM

## Quickstart

To run the main

[baremetal Raspberry Pi kernel](baremetal/raspberrypi.nothing),

    $ git clone git://github.com/tonyg/pi-nothing.git

    $ make link all

    $ cp baremetal/raspberrypi.img /PATH/TO/YOUR/RASPBERRY/PI/SDCARD/kernel.img

Boot the Raspberry Pi.

There is also a [simpler kernel](baremetal/versatilepb.nothing) for

the QEMU-emulated

[`versatilepb`](https://wiki.qemu.org/Documentation/Platforms/ARM)

machine that can be run in emulation from the host:

    $ cd baremetal

    $ make versatilepb.img

    $ ./run-kernel

A [graphical variant](baremetal/versatilepb-graphics.nothing) also

exists.

When running a `versatilepb` kernel in emulation, you're interacting

with the kernel via the emulated board's serial UART. Type characters

at it, and it will echo them. When you get bored of this, press `C-a

x` to quit `qemu`.

## Third-party software

This package makes use of a number of programs and resources

generously developed and released as free software by other authors:

 - [**disarm**](nothingc/private/disarm), a disassembler for ARM

   instructions, developed by and copyright to Gareth McCaughan.

 - [**udis**](nothingc/private/udis86-1.7.2.tar.gz), a disassembler

   for x86 and x86-64, written by and copyright to Vivek Thampi.

 - [**font0**](baremetal/font0.bin), a very simple monospace bitmapped

   font developed by and copyright to Bitstream, Inc.

 - [**raspbootin**](baremetal/raspbootin), a boot-over-serial

   bootloader for the Raspberry Pi, developed by and copyright to

   Goswin von Brederlow.

and, of course, [QEMU](https://www.qemu.org/) and

[Racket](https://racket-lang.org/) themselves.
