I need an os that would:

  • fit on wyse terminal 1200LE device (amd geode cpu, 512KB of flash, 32MB of ram)
  • run ssh server, support usb and serial connections

Is there anything out there that could be used or adapted to this purpose at relatively little effort?

I looked at FreeRTOS but that's a bit low level for my purposes, if there was some sort of tiny linux distro that I could cut down to this purpose that would be ideal. But 512KB is probably too little storage space available for this?

It would be wise to specify what you mean by "operating system". If you mean only Linux, that could change the answers significantly. MS-DOS fits in less than 512K of flash... – Mark Nov 1 '12 at 17:30
probably freedos.org too – kenny Nov 1 '12 at 17:32

The real question is: what are the high level use cases for this device? What applications are going to use the OS? – Kaz Nov 1 '12 at 18:30
The most tiny operating system is no operating system. – Al Kepp Nov 1 '12 at 18:51
That device is a thin client... it's really not meant to stand on its own. I think you're going to be hard-pressed to run any typical desktop/server operating system in 512KB of flash. – Toby Lawrence Nov 1 '12 at 19:41
