This is our short hand for saying use the development version of RTEMS,
specifically the next release called RTEMS 5. It requires cloning a couple of
git repos and using them rather than the releases. The work flow should be the
same. This code is stable at the moment and should work.

I have done this myself on a NIOS a few years ago. It is a lot of work.

When you say "changing the makefiles" who's makefiles are these?

I think I may be missing something here. Did you merge your code into the RTEMS
source tree?

This is understandable.

Do you have a JTAG debugger that can set breakpoints and step at the instruction
level?
