A6 — operating system for embedded M68k systems
(work in progress, most of these are lies until those things are actually built)
A6 (originally a shortening of AVL68KOS / AVL's 68K OS) is an operating system for use in embedded M68k computers. Some characteristics:
-
Supported CPUs currently include: 68010 (There is preliminary 68000 support but it is untested. In the future, newer ones will also probably work.)
-
Preemptive multitasking
-
IO using device files, a la *n?x
-
Memory protection support
(No support is planned for full MMUs — this is a deliberate design choice. However, future ports to more modern 68ks may understand how to turn their MMUs into MPUs).
-
Loadable kernel modules
-
Applications load from ELF files, with dynamic linking/relocation
Compiling
There is more documentation on compiling here. The tl;dr
is: you need a m68k gcc toolchain called m68k-elf-*
on your path, then build
using meson. A helper script to run all the meson commands is at ./build.sh
.
Documentation
The documentation takes the form of Markdown files located in this source tree; it can be viewed here.
Issues are managed in Gitea now, but the old issue tracker has issues that were closed prior to this migration.
License/copyright
Intellectual property is bullshit. This is everyone's code. Because it includes picolibc, you'll have to dump the big pile of IP crap from here into documentation you bundle with a binary build.
