RTEMS vs. changing hardware: Building app against RTEMS build tree?

this should work, although I did not yet try it out.

The big thing to change should be that the environment variable pointing
to the installed system should be changed from something like




what you are missing then are "Makefile.inc", "make/bsp.cfg" and
"make/target.cfg". But there should be a way to come over this.

If you have a working solution, this would be nice to see in the RTEMS wiki
