The Sunburst Project was created to get CHERIoT Hardware into the hands of embedded engineers. CHERI and CHERIoT extends conventional hardware ISAs with new architectural features for enabling fine-grained memory protection and highly scalable software compartmentalisation. Sonata is an open source hardware board (PCB), bitstream and all the constituent parts to allow engineers to experiment with CHERIoT. The Sonata design is fully open sourced under an Apache 2.0 licence. The board design has also been ported to KiCad. CHERI has been developed by University of Cambridge and SRI International. CHERIoT was created by Microsoft. Ibex is managed by lowRISC. Sonata has been prepared by lowRISC CIC and NewAE.
