Dear Mike,
I'm experiencing the same problem as you. I'm not able to communicate
with the PC using the embedded DBUG command "dn". The strange thing is
that no frames are sent from the board when the command is launched
(I'm sure because I have checked with a network analyzer). For my
case, it seems to be a transceiver problem. Connected to my PC directly,
the CML board is not able to establish a reliable link with it because
sometimes the link goes down.
If you find something about this issue please let me know (alessandro.

Best regards
