I’ve decided on the name for my Propeller OS: Largos

Sunday, May 24th, 2009

I’ve been working my rear off getting ready for the Unofficial Propeller Expo 2009 (UPEW). I intend to demonstrate Largos (“Large model operating system” for Propeller’s) at the show.

Largos is currently composed of mostly Spin code, which will be replaced by LMM code over time. At this point, Largos gets me to a shell prompt, and the shell has about two dozen built-in commands for manipulating the file system and files stored in it.

Feature set currently being debugged:

  • memory management
  • loadable device drivers
  • flash file system (with nested directories!)
  • LMM kernel
  • shell

I’m really enjoying writing a tiny OS from the ground up.
