You want to install TinyOS on *only* an FPGA? TinyOS is designed to run on a microcontroller platform, usually as part of a wireless sensor network, like the Telos or Mica platforms. It's not meant to be installed directly to an FPGA.
If you're still set on this crazy idea, there's apparently a research paper on the topic. You'll need a subscription to IEEE Xplore to use the link I have.
