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 cheriot-rtos, which is included in this repository as a submodule. cheriot-rtos contains the CHERIoT software stack as well as drivers for using the Sonata board; it is well documented by the CHERIoT Programmer's Guide.

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.
