If your uC has a JTAG interface, just use the $100 wiggler JTAG - parallel
port interface and you're done.
For non-JTAG processors, I don't know, but in a sense a RTOS is nothing
more than any other program and could probably be debugged with whatever
mechanism is available with MULTI.

Yes, I don't really know why theses guys like VxWorks charge so much for
a 20-year old technology. Their tools are great, but their licensing scheme is
insane. Long-life to open-source projects in this area...
