FreeFlyOS

A simple OS for learing! Here we go! Ale, ale, ale!Go, go, go! Ale, ale, ale!Let's do it together!

You can do memory management、multi-progress、file system and so on.

Environment

Why choose x86_64-elf-toolchain?

Because FreeFlyOS compiled and linked by this toolchain has nothing to do with the system. In fact, you can also use gcc under linux to compile the operating system, but there will be more system-related program sections, resulting in MBR exceeding 512B, so use x86_64-elf-toolchain to Minimize the OS.

I only test in my Mac OS(x86-64) and Ubuntu(x86-64).It takes a long time to set up the environment, please be patient.
