Is there no way to register both a down producer and converter in a single
…so file? I have no problem registering my down producer but not the
converter. I had do a printf and it always report " cannot register
convertor." The following is part of my code snippet. Someone help please
… thank you…

Yes it’s possible. Whats the errno when the reg fails?

It’s probably EINVAL: a converter needs both
rx_up() and rx_down() specified.

Yes you are correct. The convertor can be registered when I specify a dummy
rx_down() function for the convertor. For your information, the error
message I got was : invalid argument
The network ddk never mention about this.
Thanks sean, you are great.
