Dear Vijay,
thank you very much for your effort to bring some order here ;-)
I am currently trying to get EPICS to work on RTEMS6 as well.
I already failed with the legacy stack because configuration variables
like
RTEMS_HAS_NETWORK are not set with the waf-builder.
That's why I quite happily jumped on your legacy-net-extra
(For the beatnik CPU on which I can test directly on the hardware).
Unfortunately, it doesn't quite work yet:
