Sonata is a system for evaluating the usage of CHERIoT Ibex core as a microcontroller for embedded, IoT and Operational Technology applications. The system contain a number of peripherals (I2C, SPI, GPIO, PWM, UART, and DMA) and a CHERIoT enabled debug module along with the CHERIoT Ibex core itself. It is designed for use on FPGA and specifically targets the Sonata FPGA board.
It is under active development and the first full RTL release is not yet complete. In the meantime, please read the architecture specfication.
We plan to release an updated image, together with instructions for uploading it to the board over USB, before the May 29th 2024 Hackathon event. This image will allow running CHERIoT-RTOS and will allow for general purpose software development.
Sonata is part of the Sunburst Project funded by UKRI / DSbD under grant number 107540.
