Message Passing TX and RX reset in C6455 EVM

Started by rena...@gmail.com March 12, 2009
Hi there:
I am doing a test using SRIO message passing between DSP 1 and DSP 2 in the C6455EVM. Looks to me, the TX in the DSP 1 is successful. The ownership of the buffer descriptor in the TX is reset to 0 after the message is sent out. cc value is 000 (good completion). However, on the RX side in the DSP2, the receiving buffer desciptor is never reset. That caused the program never ending normally. I have to reset the EVM board for another successful test.

Does any one can give me some hint on what prevents the RX to reset the receiving buffer desciptor?

Thank you very much
