# Sonata software

This repository contains software, build flows and examples for the [Sonata System][] running on the [Sonata PCB][].
For a guide on how to get up and running on building software for the sonata board see the [getting started guide][].
After you are all set up, take a look at the [exercises][].

## Orientation

You are in the [`sonata-software`][] repository.
This repository wraps the [`lowrisc/cheriot-rtos`][], adding some Sonata specific demonstration code on top of the CHERIoT stack.
The [`lowrisc/cheriot-rtos`][], included in this repository as a submodule, is a fork of the upstream [`CHERIoT-Platform/cheriot-rtos`][].
[`CHERIoT-Platform/cheriot-rtos`][] contains the CHERIoT software stack; it is well documented by the [CHERIoT Programmer's Guide][].
*The [`lowrisc/cheriot-rtos`][] fork only exists to hold fresh patches that aren't quite ready to be upstreamed to [`CHERIoT-Platform/cheriot-rtos`][] but will be.*

Other repositories of note:
- [`sonata-system`][]: holds the Sonata system RTL and bootloader which come together to generate the bitstream.
- [`sonata-rp2040`][]: The firmware that is running on the Sonata's RP2040 microcontroller and emulates the 'SONATA' drive when you plug it into your computer.
- [`CHERIoT-Platform/llvm-project`][]: The CHERIoT LLVM compiler toolchain.
- [`cheriot-audit`][]: A tool to explore and verify the relationships between CHERIoT RTOS components.
- [`CHERIoT-Platform/book`][]: The source of the [CHERIoT Programmer's Guide][].

For hardware documentation, see the [Sonata system book][].
