Building RTEMS Cross Compilation System (RCC), has a different directory structure compare to building RTEMS from source (might not be true). This will run RTEMS on leon3 in a renode simulation.

To run the simulator in docker container

renode

If you face GTK protocol error then exit the container, run xhost + local: and restart the conatiner to allow other users (including root) run programs in the current session.

In the renode window, run

start
s @renode-rtems-leon3/leon3_rtems.resc
