LastOS

(note: i didn't decide to project name, if you have any suggestions, open a pull request)

A unix-like os is about to being yours, light and open for risc-v64.

Motivation

Myos is designed for risc-v cardboard and embedded systems. And it's focuces to simplicity, and running on low-spec hardware. Linux is too heavy and unneceserry for riscv embedded systems,such as car, elevator, or even a strech machine gui control panel.

Supported systems

• Qemu
• Vision Five 2 (Future planned)

Contribitions

Fork it, hack it, test it, pull it.
