Hi, Dear All:
 
Is anyone can tell me how to start to read/write a Ethernet port for DM355? 
What is the documentation I should refer to?
 
I post before but did not insert right subject. sorry for that.
 
Thanks,
Elbert

You dont need to call Memory_unregisterContigBuf, just alloc and
free the buffers via CE and CE will know that you are calling it with a
smaller buffer inside a larger one that it knows the translation to...

Thank you Vladimir,
But we are not able to allocate and free via CodecEngine due to the
structure of our application and the need to call the alloc not before
calling CERuntimeInit().
