Serial Comm between LattePanda CPU and Arduino not Working

I am concluding there is something wrong with the LattePanda Hardware or firmware that is not allowing a simple serial message sent from the LattePanda's CPU to the Arduino. Comm from the Arduino to the LattePanda CPU works fine.
the other way around works fine.

Please see this thread for all the work i have done trying to get this working but to now avail.
viewtopic.php?f=6&t=1429. Note that the same simple C# and Arduino code works on an external Arduino (Mega 2560).

Any help on how to fix this would be greatly appreciated.
