This project provides a minimal kernel, ABI, and user-space applications to experiment with OS development on constrained hardware. This project provides a minimal kernel, ABI, and user-space applications to experiment with OS development on constrained hardware.
## Status
Basic synchronous applications are working great.
Current focus is on **expanding the ABI syscalls** and **fixing the MSC/USB-SCSI driver** to make application development easier and smoother.
