I don't think C6711 silicon supports HSRTDX. Also, with the DSK 6711, RTDX will be
slow.

As far as project file compatibility goes, a 6713 file could work with 6711 but first
you must carefully verify several things, including silicon capabilities (as
mentioned), memory config, and I/O config (such as serial port allocation and type,
for example McBSP vs. McASP).

For example RTDX code and CCS projects, there should be lots of examples on the web.
A quick search found this tutorial for the DSK 6711:

Or maybe someone in the group can send you something. I don't have anything; back in
the day with 6711 we used HPI because it was way faster.

Actually the 6711 does support HSRTDX and it is fairly fast [some
number of Mbits] - the catch is that it requires the 'magic IO
hardware' on an XDS560.

oops - I didn't get this far into the original message. If you have
an XDS560, you need to define the symbol 'HSRTDX' in your project.
