The 0.2 version should be a more stable kernel, which can work at least on fx9860G/fx9860GII sh3-based platforms (including the several hardware design designed by the same commercial name). It should be possible to run it with the bootloader, and to use USB CDC/ACM to provide an emulated serial console through a computer.

The kernel is not expected to be fully functionnal, but should be usable by simple userland processes, without known major issue.
